What is PM Variable Speed Screw Compressors

PM Variable Speed Screw Compressors are available in both fixed speed and variable speed. A variable speed screw compressor incorporates variable speed drive technology. A special drive in this type of compressor controls the speed (RPM) of the compressor. PM Variable Speed Screw Compressors work to maintain a constant air pressure, while the motor speed adjusts to meet the production air demand. Indeed, variable speed machines reduce engine speed aligning it with the actual air demand, saving energy.

Advantages of PM Variable Speed Screw Compressor

Energy Savings

The biggest advantage of a PM Variable Speed Screw Compressoris energy savings. A fixed speed compressor always draws the amount of power needed to meet the maximum compressed air demand. VSD will ramp down RPM, and therefore power consumption, when demand for compressed air is lower. Depending on the total volume of compressed air used in your facility and the amount of variability in your processes, this can add up to hundreds, thousands or even tens of thousands of dollars in energy savings each year

Wide Range Of Business Applications

It turns out most air compressor applications can benefit from variable rates. Whether you are in manufacturing, the food and beverage industry, or health care, there are times when you may need varying levels of compressed air. A fixed speed compressor would run at the same standard level of output for all of these services, no matter your needs.

How Does a PM Variable Speed Screw Compressors Work?

Rotary screw compressors operate via positive displacement-meaning they draw air into a chamber, reducing the volume. Air is drawn into one or more of its compression chambers, which are then closed from the inlet. As the volume of each chamber decreases, the air is compressed internally until the pressure reaches the designed built-in pressure ratio. The valve then opens and the air is discharged into the outlet system.
A rotary screw compressor's defining characteristic is the presence of screws (usually there are two, but the compressor may have more or less). These are also called the male and female rotor elements, and they are driven either by the male rotor or by a timing gear. In oil-injected screw compressor technology, the male rotor drives the female rotor. In oil-free compressor technology, a timing gear drives both rotors for harmonic running, with minimum calculated clearance between both elements.
The twin elements rotate and spin in opposite directions. Air fills the space between the rotors and, as they rotate, the volume between them and the surrounding housing decreases, squeezing or compressing the air into a smaller space. The compressed air is then displaced to the outlet. Beyond that, there are no valves, or other mechanical forces that can cause unbalance, which allows a screw compressor to operate at high speeds while combining a large flow rate with small exterior dimensions.
One note: although they belong to the same class, rotary screw compressors are more complex than piston compressors. As such, the speed of the screw rotors is optimized at a certain level. This is to minimize mechanical losses (due to heat at very high speed) and volumetric losses (air losses due to very low speed) during compression.

What is the Difference Between VFD and VDS?

Variable speed drive (VSD) is any technology that drives the load and can adjust its speed. The solutions are based on electrical, mechanical or hydraulic principle.
Steam turbine is a mechanical driver. In conventional thermal power plants the turbine runs at constant speed as the frequency of the generator shall match the frequency of the power grid. However, steam turbine can be used for variable speed control as well. Certain industrial processes (e.g. refineries) produce steam as a by-product. Therefore, it might make sense to use such steam in a turbine to drive e.g. compressors.
Gas turbine is a mechanical driver, too. In fact, gas turbine is the main competitor of VFD in Oil & Gas industry to drive fix speed and variable speed compressors.
Hydrodynamic coupling, also called fluid coupling, is a hydraulic drive. It is used in combination with electric motor to adjust its speed in a limited range. Hydrodynamic coupling can only reduce the speed of the motor.
DC motor drive is also a variable speed drive when used with a controllable DC voltage source. In fact, DC drive was a benchmark for variable speed technologies due to its high performance and straight forward control implementation (at constant excitation speed is proportional to the induced voltage and torque to the armature current) .
Variable frequency drive (VFD) is another solution for variable speed control. The term VFD is used specifically for power electronic based frequency converters that supply AC electric motors. VFD can be realized as current-source inverter (CSI) or voltage-source inverter (VSI).

Frequently Asked Questions

Q: What is a variable speed compressor?

A: A variable-speed drive (VSD) air compressor is an air compressor that takes advantage of variable-speed drive technology. This type of compressor uses a special drive to control the speed (RPM) of the unit, which in turn saves energy compared to a fixed speed equivalent.

Q: Is variable speed compressor better?

A: While variable speed compressors are more energy-efficient for most applications, there are some exceptions to the rule. If your compressed air needs are constant, or even mostly constant with only occasional slight variations, a variable speed compressor may not be necessary.

Q: Why use VFD in compressor?

A: With a VFD installed, you will optimize the performance of your motor and the entire air compressor system which reduces stress on the other components of the system. Reduced stress improves the working life of these parts by almost eliminating the unnecessary wear and tear, prolonging maintenance and repairs.

Q: What is the difference between a variable speed compressor and a fixed speed compressor?

A: A VSD compressor is a smart choice when demand for air varies by process, time of day, shift or time of the year. When demand fluctuates, a VSD compressor that varies its speed is much more energy efficient than a fixed-speed compressor that can only run flat out.

Q: Do I need a variable speed compressor?

A: Variable speed compressors are much more energy-efficient than single stage systems. If your home only needs to be cooled down by a couple of degrees, a variable speed unit won't waste energy running at full capacity. It also doesn't turn on and off as frequently as a single stage unit, which reduces energy usage.

Q: Do variable-speed compressors last longer?

A: When sized appropriately, a variable speed compressor can theoretically last longer than a single-stage PSC compressor because the motor isn't loaded like a PSC motor. Instead of simply being on and off, a variable speed compressor gradually ramps up.J

Q: How do you select a VFD for a compressor?

A: VFDs for reciprocating compressors should have at least 160% overload capacity, whereas VFDs for screw compressors should have at least 110% overload capacity. These VFDs should be of constant torque type.

Q: Is inverter compressor same as VFD compressor?

A: With Variable Frequency Drive (VFD) technology, chillers are able to match the varying load requirements, regardless of requirement. The Inverter technology modulates the speed of the compressor's motor continuously.

Q: How does VFD convert DC to AC?

A: How a VFD Works. VFDs employ an AC to DC converter, a DC bus, and a DC to AC inverter to produce a variable voltage and frequency AC output. AC input voltage is passed through a diode bridge which produces a rectified DC voltage on the DC bus.

Q: How does VFD vary compressor capacity?

A: A VFD works by converting the input current to direct current, and, from this, generating a simulated AC signal at varying frequencies. Varying the frequency will vary the motor speed, thus varying the compressor capacity.

Q: Is a variable speed compressor the same as a single speed?

A: A single-stage has shorter, more frequent on and off cycles. A variable-speed AC (and, to a lesser extent, a 2-stage air conditioner) runs at a lower setting (using less energy) for longer periods of time and has fewer on/off cycles.

Q: Can a compressor last 20 years?

A: Generally speaking, the average air compressor can last anywhere from five to twenty years with proper maintenance. Factors such as compressed air temperature, humidity, and usage affect how long an industrial air compressor lasts.

Q: Which compressor lasts the longest?

A: Rotary screw air compressors last longer than reciprocating air compressors. Like an engine, reciprocating compressors have piston rings and other components that contact each other and wear over time. With that wear comes a decrease in performance, oil carryover, and more heat generation.

Q: Is a screw compressor more efficient than a piston compressor?

A: Pistons have a lower initial cost than screws, but screws cost much less to operate over time. Energy Efficiency. If both a piston and a screw were running the same amount of hours, the screw compressor will be much more efficient and have lower operating costs than the piston over the lifetime of the compressor.

Q: What is the efficiency of a variable speed drive generally?

A: VSDs are typically 92–95% efficient with 5–8% losses being due to additional heat dissipation caused by the high–frequency electrical switching and the additional power required by the electronic components.
