A Review on Helical Rotor Pumps and How They Contribute to Manufacturing IndustriesNovember 9, 2018
As a key concept, a helical rotor pump's ability to convey many types of fluids does benefit the manufacturing industry. Speaking of different fluid types, we're not limiting this post to semi-solids and thick, gooey pastes. In this sector, this pump category is also expected to gently convey the abrasive loads that float suspended within those fluid mediums. Built as all-around industry contributors, such talents deserve highlighting.
Use of Pump Rotors in Poultry and Meat Processing IndustryOctober 23, 2018
In a progressive cavity pump, a mechanism that's using a helical rotor, food industry mediums are being processed by the chrome-plated component. The near-solid mix contains soft tissue, which means there's raw meat moving in discrete pockets around and through the screw pump rotor.
What are the Limitations of Helical Rotor Pumps?October 16, 2018
Helical rotor pumps are efficient. They feature an all-important discrete pocket pumping capability, transport semi-solid fluids that would defeat other pumps, and they're clearly packed with superior flowrate-managing characteristics. However, even though the above features are desirable, essential even, the technology does have its limitations, just like any other equipment type. Anyway, having talked so often about benefits, here's a brief look at those limitations.
Pump Reconditioning Process and How It Can Save You MoneySeptember 25, 2018
Pumps are reliable devices. Even when they're in service, day-after-day, for weeks and months on end, they function reliably. By design, it's a set of stringently enforced engineering values and production standards that make sure they're equipped with this long lifespan. Even when those features wane, there's a pump reconditioning service to provide a lifespan reclaiming support service.
Effects of Worn Rotors in Sewage and Sludge PumpsSeptember 12, 2018
It is easy to look at your sewage or sludge pumps as a fixture of your plumbing system without the need of ever taking a closer inspection. However, without a closer inspection, we would not be able to identify the many problems that can crop up with your pumps during the lifespan of their operation. With sewage and sludge pumps, one of the most common issues that you will run into is that of worn rotors. Rotors are incredibly important not just for the operation of your pump but for the operation of your entire system.
Life Expectancy of Pump RotorsAugust 27, 2018
On paper, pump rotors are uncomplicated components. They rest on bearings, rotate within stators, and there's very little that can go wrong. In the real world, however, there's so much that can and often does go astray. Accumulating over time, these faults impact the shaft's performance. Essentially, the life expectancy of pump rotors is influenced by many factors.
What is Pump Cavitation and Its Common Causes?August 13, 2018
There's a drive-hampering phenomenon that we've mentioned several times in past articles. Referred to by engineers as "Pump Cavitation," the issue attenuates flow performance. Again, that fact has been covered several times, but what is cavitation? Pump repairers must understand this fluid effect, must know all about its causes and the conditions that produce the flow-hampering issue. For starters, is cavitation really just a verbose way of talking about bubbles?
The Role of Coupling Rods for Progressive Cavity PumpsJuly 25, 2018
There's a prime mover on the floor, bolted to a concrete plinth. Further down the line, a progressive cavity pump is ready for its first day of work. Moving between those two key drive sections, there's the coupling rod. This is the bridging or connecting component that hooks the prime mover to the pump mechanism. Starting at the drive shaft, let's see where the powertrain takes the rotating energy.
Pump Reconditioning Services in Melbourne: Cost-Efficiency BenefitsJuly 10, 2018
This time around, the accounting department gets an opportunity to promote pump reconditioning services. Clearly, having a well-equipped rotor reconditioning workshop in the Melbourne area is an engineer's dream. Parts exit the system rapidly, then a locally dispatched tech rapidly dismantles the helical pump. Meanwhile, those localized repair efforts are making the entire process more cost-efficient than ever before.
What Makes Progressive Cavity Pumps Versatile for Industrial Uses?June 25, 2018
Progressive cavity pumps work well in tough pumping applications. Streaming high or low viscosity fluids, the extended positive displacement units maintain a fixed output. Even when the NPSHR (Net Positive Suction Head Required) is pitifully inadequate, the screw mechanism and its surrounding stator keep right on operating. Taking these performance-based attributes into account, helical pumps are clearly built to satisfy the most challenging industrial applications.
Rotor Re-welding Services in Melbourne: How Is This Done?June 12, 2018
Progressive cavity pumps, machines that resemble long and smooth mechanical assemblies, function smoothly as their drive systems hum with power. Inside their cylindrical housings, advanced synthetic rubbers form stator sleeves while strong metal rotors turn inside that flexible glove. But wait, the rotor is marked with nasty material-subtractive gouges.
Rotor Pump Recutting Services in Melbourne: How Does Recutting Work?May 21, 2018
Helical rotor pumps are reliable. However, there are antagonistic forces in play within the machinery. Suspended solids and sharp-edged grains are abrading the rotor metal. In the meantime, high stream temperatures and caustic chemicals are causing stator expansion. Again, it's the rotor that feels the brunt of the compressive assault, and the damage to the metal is taking its toll.
Benefits of Using Progressive Cavity Pumps for Viscous Chemicals in Manufacturing IndustriesMay 10, 2018
In the manufacturing world, there will occasionally be times when machines are needed in order to transfer viscous liquid from one area to the next. During these scenarios, a special type of pump is brought into play. There is a vast array of different types of liquid required in the manufacturing industry but we will be focusing our discussion on viscous chemicals. Viscous chemicals require a special transportation pump called a progressive cavity pump.
Signs of Problematic Drive Shafts in PumpsApril 26, 2018
A drive shaft, or drive shaft, is one of the most important central mechanical components within your pump. The drive shaft is used as a bridge for kinetic energy to be transferred in order for the entire pump to properly operate. As such, your drive shaft will have to be able to endure constant rigours and stress despite being in the relative comfort of the pump's housing. In order to keep your impeller rotating, you need a healthy drive shaft.
Significance of Pumps in the Agricultural IndustryApril 10, 2018
A daily rain shower, a scheduled cloudburst, sure would come in handy when the crops in a field were thirsty. Topped off by an evening drizzle, crop yield would swell. The on-tap resource, just falling from the heavens, wouldn't ever stop. In lieu of this fanciful notion, pumps nurture those crops and keep the agricultural sector hale and hearty. When gravity and nature fail, pumps take up the slack.
Rotors and Stators for Progressive Cavity Pumps: How They WorkMarch 29, 2018
Some confusion surrounds rotor and stator talk. First of all, standard synchronous motors employ these two essential prime mover components, but they're both constructed from electrical windings. On the other hand, progressive cavity pumps utilize mechanically interlocking components.
Rusty Pump Rotors: Should you Replace or Resurface?March 16, 2018
Pump reconditioning specialists are used to asking tough questions. This newest one, the decision to recommend a replacement rotor or a resurfacing operation, is harder to answer than most. Fundamentally, the solution can't be issued with any insurance until the rotor has been properly checked.
Accuracy of Universal Rotor Cutting Machines for PumpsFebruary 28, 2018
A look at a universal rotor cutting machine takes us neatly into familiar territory. As mentioned previously, the machined helical geometry assigned to this rotating shaft isn't cut arbitrarily. Quite the opposite, the rotor cannot form a fluid-conveying relationship with its stator unless it's machined accurately. This interference fit facilitates the formation of discrete fluid packets. Cut poorly, those isolated fluid packets will leak. Let's talk about rotor-cutting accuracy.
Tips to Help Prevent Pump Stator FailureFebruary 14, 2018
Progressive cavity pumps are remarkable devices. The elongated pumps split fluid loads into discrete packages. They accomplish this feat without mixing the fluid, so they're employed in many fluid-based beverage and food applications. Built to handle messy effluent streams, this screw-like rotor can pump abrasive solids.
Causes of Drive Shaft Failure in PumpsJanuary 29, 2018
Power flows through a drive shaft. The kinetic energy rotates a universal joint, it arrives at a pump housing, and an impeller rotates. It's a simple enough sequence, one that relies on this vital bridging rod. Unfortunately, drive shaft failures do occur. Subsequently, when that coupling breaks, the pumping mechanism is isolated from the power source.
Causes of Abrasion Problems in Helical Rotor Pumps?January 12, 2018
While its armour-plated rotor smoothly delivers a turgid load, a nominated helical rotor pump functions flawlessly. The long screw-like mechanism operates well within its design parameters, it creates packets of viscous fluid, and the flow is regulated. There is, however, an adverse condition accompanying that smoothly regulated stream.
