DOES YOUR PROGRESSIVE CAVITY PUMP NOT START?
These positive displacement screw pumps are great for moving thick paste-like fluids at an even speed and pressure but are often problematic with abrasive and aggressive waste-streams.To get more news about Screw pump rotor, you can visit hw-screwpump.com official website.
Whatever your application, if you have an issue with a faulty progressive cavity pump try this checklist for possible solutions.
Here's our trouble-shooter for a variety of progressive cavity pump (screw-pump) issues:
Check the power supply matches the pump motor voltage and amps.
Check that the fuses haven't blown.
Has the pump been idle for some time? The rotor and stator may have ‘bonded', if it doesn't turn then check for dried debris and lubricate with an appropriate oil or glycerin.
Has the cable or its connections been damaged? If so, have the damaged section replaced.
Check that the motor windings haven't burnt out.
Have the pumped fluid's properties changed? Tight tolerances on progressive cavity pumps mean that if the media's viscosity or temperature do not match the pump's specification it can lead to thermal expansion. This could burn the rotor and stator where they rub or even jam it, stopping all movement and putting strain on the motor.
Examine the rotor to make sure it's not blocked or jammed. If it is, then withdraw it from the pump, clean down and if there is no damage evident, reassemble.
Try reducing the pump's rotation speed before switching it on, also check the delta start settings if it is an older 3-phase motor, or invertor settings on a newer 3-phase. Generally, the larger the motor, the longer the time delay between start up and full power is needed. If the pump starts okay on a low speed, wait until it has discharged steadily for a time before increasing speed step-by-step to normal operation.
IS THE PUMP GIVING TOO LITTLE OUTPUT?
Check the feed intake is supplied and that the pump's inlet is fully submerged. Stop the pump and isolate the power while you check for blockages at either end.
Check the motor is rotating in the correct direction. If not, the wiring needs correcting before it is started up again.
Has performance reduced over time? Check the wear parts and replace them if worn out. Progressive cavity pumps rely on tight tolerances and abrasive slurries can soon wear down the stator walling and rotor edges.
Examine the discharge pipework and replace it if leaking or cracked.
Another reason why the pump may be giving too little output is if the final discharge head is too high; where this is the case, you may need to use a larger pump or an alternative type.
Check that the rotation speed is correct. Reduced speed for the same power draw could indicate something jamming inside the pump, or the fluid's viscosity is too high for the pump configuration.
Seven Reasons for Using a Progressing Cavity Pump
Applications where a low NPSH is required, are very challenging for pump manufacturers. It is often necessary to take structural precautions to increase NPSHa values and thus ensure the safe operation of the pumps.To get more news about screw pump stator, you can visit hw-screwpump.com official website.
Especially in the oil and gas industry, liquids close to vapor pressure have to be conveyed regularly. Therefore, applications with low NPSHa are daily business. This requirement makes the design of pumping systems more complex. Often, either plant-side adjustments or NPSH optimized costly design adjustments have to be made to the pump system. By choosing the right pump technology however some complicating factors can be eliminated from the beginning. Often, progressing cavity pumps are only used for highly viscous or solid-laden media. However, they offer numerous advantages especially for applications with low NPSHa.
1 Very low NPSHr
Compared to other pump technologies progressing cavity pumps you can handle a very low NPSHa without expensive constructional adjustments. In the standard design, the values for horizontal pumps are well below 1.5 meters. With NPSHr optimized pump selections, values of well below 0.5m are possible.
2 Cost-effective and space-saving
Some pump types can only cope with a low NPSH in special versions or with special designs, resulting in high acquisition costs for you as a customer. The progressing cavity pump is often a more cost-effective alternative, as it already covers a wide range of NPSH critical applications in standard design. In addition, you can often use the progressing cavity pump in a horizontal design even with low NPSHa values. This saves additional costs for you compared to other pump types that are already designed submerged in these cases. Easy access for repair and maintenance work is guaranteed. Especially for larger installations, you no longer need to use cranes to lift submerged equipment. On-site adjustments to increase the NPSHa, such as installing pumping technology in shafts or the elevated installation of containers, are completely eliminated for you as a customer.
3 Handling changing viscosity and solids
You can handle media containing solids several centimeters in diameter with progressing cavity pumps. This is a decisive advantage for you in applications where solids are expected because other types of pumps often clog. Furthermore, you can cover a wide viscosity range with our progressing cavity pumps without losing efficiency.
An Informational Brief on Polymer Machining
Polytetrafluoroethylene (PTFE) is a fluorocarbon-based polymer, known more commonly as Dupont's brand name Teflon®. The enhanced electrical properties, high-temperature capabilities and chemical resistances of this thermoplastic make it a favorite for backup rings, coatings, distribution valves, electrical insulation applications and more.To get more news about machining teflon, you can visit runsom.com official website.
Our latest machining guide discusses what goes into machining Teflon and how its considerations differ from other manufacturing options such as metal machining, injection molding, and 3D printing.
Read on to learn more about Teflon's machining, applications and properties in AIP's informational polymer brief below, starting with the difference between working with a thermoset and a thermoplastic.
All polymers can more or less be divided into two categories: thermoplastics and thermosets. The main difference between them is how they react to heat. Thermoplastics like Teflon, for example, melt in heat, while thermosets remain "set" once they're formed. Understanding the technical distinction between these types of materials is essential to CNC machining them properly.
What type of thermoplastic is Teflon in particular? PTFE is a fluoropolymer, making it a semi-crystalline thermoplastic. As a fluoropolymer, PTFE possesses an inherent high resistance to solvents, acids and bases.
Properties & Grades of Machined Teflon
Teflon has excellent electric stability in a wide range of conditions and environments, and its coatings are popular in the aerospace sector. Offering excellent chemical resistance and sliding properties, PTFE finds many applications in seals, housings, linings and bearings. Teflon also maintains very good UV resistance, hot water resistance and electrical insulation at higher temperatures.
Unfilled PTFE is chemically inert and has the highest physical and electrical insulation properties of any Teflon grade. Mechanical grade PTFE is often made up of reground PTFE and exists as a cost-effective alternative for industries that don't require high purity materials while providing superior compressive strength and wear resistance to virgin Teflon.
There are several different modified PTFE materials available with unique properties. Many of these modified grades offer greatly reduced deformation percentages under load, as well as a lower coefficient of friction. These include glass-filled, nanotube, synthetic mica and carbon-filled grades. Teflon (PTFE) is more commonly used as an additive to numerous other base polymers in order to provide reduced friction and wear properties.
Benefits Of CNC Machining With Brass
Brass is a special copper alloy. Brass is an object made of an alloy of copper and zinc. It is named for its yellow color. Brass with a copper content of 56% to 68% has a melting point of 934 to 967 degrees. Brass has good mechanical properties and wear resistance. Because of its unique advantages, it has become an important part of the component manufacturing industry. Generally, it is used more in precision copper parts such as auto parts, medical parts, and electrical parts. Brass CNC manufacturing has many advantages over other metal CNC machining processes, which is the reason for the demand. This article discusses several benefits of CNC machining with brass.To get more news about brass cnc machining, you can visit runsom.com official website.
High-Speed Machining
Brass has excellent machinability, sometimes referred to as 100% machinability. The mechanical properties of this alloy are high strength, high tensile strength and shear resistance. These characteristics contribute to the processing speed when using brass. Studies have shown that machine shops can and should process materials at feeds and speeds (usually 5 to 20 times faster) that are much faster than current increases in productivity and profitability.
For example, today's brass rod materials are not only easier and faster to machine, but it also has no negative impact on tool wear, surface finish of parts, or chip formation. With the powerful features and robustness of the latest high-speed machine tools, the shop can increase the removal rate of brass workpiece material in milling, drilling and turning operations. Moreover, according to research, alternative materials such as steel and stainless steel also lack the competitive high-speed processing advantages brought by brass.
Precision Machining And Dimensional Stability
Brass is known for its dimensional stability and is also suitable for manufacturing with strict tolerances. Due to the smaller deformation coefficient and higher impact resistance, the dimensions of the brass components remain stable.
High Workpiece To Tool Compatibility
In brass CNC machining, the formation of chips is negligible, so tool wear is minimal. Generally, brass rod workpieces are the first choice for CNC machining. These workpieces are highly compatible with various CNC machining tools. Tool durability and frictionless machining can improve machining efficiency.
Higher Productivity And Profit
As a fast and precise machining process, brass CNC machining can improve machining efficiency. Brass is a relatively economical and convenient material, so it is conducive to capital investment in processing materials. The durability of the tools in this process is high, so the cost of frequent tool replacement is reduced. In addition, no post-machining processing is required in this process. Together, these factors lead to higher productivity and profits.
Environmental Protection
Brass is a copper alloy that can retain the chemical or physical properties of natural copper. However, some properties of this alloy have been enhanced. Therefore, the materials in this process are environmentally friendly. In addition, brass CNC machining will not inject any harmful gases or chemicals into the environment. Brass can also be 100% recycled. The high scrap value of brass allows manufacturers to cover most of the initial raw material costs through scrap buyback programs. The scrap is then processed in the form of fragments to produce new brass again and again without losing the properties of the material.
How precision machining is impacting the future of medical device fabrication
Industry 4.0 is in full gear, and more and more companies are making the step toward digital manufacturing. CNC machines are chipping away material at blazing speeds with enhanced artificial intelligence and accuracy, ensuring that the product meets the intent of the design engineer.To get more news about 5 axis cnc machining services, you can visit runsom.com official website.
With precision machining, the struggle for geometric dimensioning and tolerancing is over, since parts will be consistent with the 3D model to the micron.
This is a considerable achievement, since deviations are often visible across parts of the same batch, causing high scrap rates and failures to meet performance requirements.
Computer numerical control (CNC) does not hold onto heat-affected zones or other mechanical flaws of 3D printing, which is more suitable for prototypes and preoperative planning models. By milling the material as-is, it retains its homogeneous mechanical properties for meeting higher quality standards.
Precision technology is not just an incremental improvement. It has a radical impact on medical applications.
It's capable of making long-lasting parts that can be carried on or inside the body for a good part of a lifetime. Solutions that were hitherto impossible can now enable new forms of microsurgery, such as on embryonic infants, blood vessels, or the brain.
With precision technology, the product casing, internal architecture, electronics integration, and cabling solutions for your biometric tracker or digital X-ray are optimised. For wearables like heart monitor implants or pacemakers, their minimally invasive form factor with ultra-thin walled micro moulded enclosure is game-changing both in terms of comfort and aesthetic sensibility.
The instruments it makes also enable robot-assisted surgery like heart valve surgeries. And we witness great growth for tiny parts like septums, sensors, microelectronics, microneedles, stents, and micro-machined screws. Needless to say, this requires great specialisation on the part of the supplier.Based on body scans, these complex solutions can be machined to be exactly attuned to the patient's biomechanics. This stands in stark contrast to traditionally hand-made components. With a precision-machined product, there is no more human error, no patient dissatisfaction, no second operation.
Professionals like surgeons and dentists benefit from having access to precision manufacturing. To their preference, they can now develop custom tools such as cutters, biopsy needles, implant holders, forceps, nebulisers, and blade handles, or outfit the robotic assistant with custom grippers.
In the future, medical professionals will use digital customiser apps to create bespoke components to spec, locally, and on demand.
MEA On China's Objection To Amit Shah's Visit
A day after China criticised Home Minister Amit Shah's visit to Arunachal Pradesh, the Ministry of External Affairs on Tuesday said the northeast state was an "integral and inalienable part of India".To get more latest entertainment news, you can visit shine news official website.
Rejecting China's remarks on Shah's visit, MEA spokesperson Arindam Bagchi said such objections do not stand to reason and will not change reality.
"We completely reject the comments made by the Chinese official spokesperson. Indian leaders routinely travel to the state of Arunachal Pradesh as they do to any other state of India," Bagchi said in a tweet.Arunachal Pradesh was, is and will always remain an integral and inalienable part of India. Objecting to such visits does not stand to reason and will not change the above reality," he said.
Bagchi was responding to media queries on the Chinese reaction.
On Monday, Amit Shah visited Arunachal Pradesh and launched the 'Vibrant Villages Programme' from Kibithoo, a village along the India-China border and India's easternmost place. Addressing a gathering, the Home MInister, in a clear message to China, said no one can dare cast an evil eye on India's territorial integrity and encroach even an "inch of our land"."Times when anyone could encroach on Indian land have passed. No one can question India's territorial integrity. Nobody can take even an inch of our land," he had said.
Last week, China "renamed" some places in Arunachal Pradesh that it claims as part of its territory. This is the third time that China has "renamed" places in Arunachal Pradesh, which it calls "Zangnan, the southern part of Tibet".
While talking to reporters, Chinese Foreign Ministry spokesperson Wang Wenbin said, "Zangnan is China's territory".
"The Indian official's visit to Zangnan violates China's territorial sovereignty, and is not conducive to the peace and tranquility of the border situation," he said, as quoted by news agency Reuters.

SCB warns against Forex multi-level marketing scam
The Securities Commission of The Bahamas (SCB) yesterday warned Bahamians against engaging in a risky, multi-level marketing scam which has become popular locally in recent months.To get more news about scb regulated forex brokers, you can visit wikifx.com official website.
In a notice, the SCB stated it is very concerned that members of the public are being solicited to join the foreign exchange market, or Forex.
According to its website, trading on Forex involves “the buying of one currency and simultaneous selling of another” in which “traders attempt to profit by buying and selling currencies by actively speculating on the direction currencies are likely to take in the future”.
“There are various programs and/or schemes which are becoming increasingly popular in The Bahamas, as they are reportedly offering Forex training to the general public so that purportedly persons can ultimately engage in trading for themselves,” the SCB revealed yesterday.
“These entities are not in any way licensed or sanctioned by the commission. Individuals should be aware that Forex trading is a highly speculative activity that carries with it a significantly increased risk of financial loss. Those persons who engage in Forex trading solely for themselves should be aware that losses can go well beyond the amount of their initial investment.”
The SCB also noted that it is an offense for persons to trade in Forex for and on behalf of other persons without being registered by the commission.
“In light of the above mentioned, the commission is very concerned and advises the public to be aware of these unregistered individuals, or entities that are operating in or from within The Bahamas,” the notice states.
“Further, the commission urges the public not to engage, or continue any dealings, with these entities or related persons.”
