What are the advantages and disadvantages of sliding vane air compressor and screw compressor?

Sliding vane air compressor, also known as Matai air compressor, is more stable, energy-saving and has a long service life than the screw machine.

<> Shenyang Weiner General Equipment **** is a professional sliding vane air compressor manufacturer, and is the pioneer and pioneer of sliding vane air compressor in China.

Now it is not recommended to use sliding machines, but screw machines, especially frequency converters, to save energy.

The design life of the main engine of the sliding vane machine is as long as 30w hours, which is unmatched by any other type of compressor, and the sliding machine does not have the link of overhaul of the main engine, so a large part of the cost can be saved in the use cost of the end user, and the speed of the sliding vane compressor is 1000-1500 rpm, so the key components of the sound have a long service life.

Sliding vane compressors.

1. The structure is simple, the parts are few, the processing and assembly are easy to achieve, and the maintenance is convenient.

2. Smooth operation, low noise, low vibration and low starting impact.

3. Compact structure, small size, light weight, easy to install in narrow space.

4. Large gas transmission capacity, uniform flow, small pulsation, no need to install a large gas reservoir.

Screw compressors.

1. High reliability: the screw air compressor has few parts and wearing parts, so it operates reliably and has a long life.

2. Convenient operation and maintenance: the operator does not have to go through a long time of professional training, and can realize unattended operation, the operation is relatively simple, and the exhaust gas supply can be supplied according to the need.

3. Good power balance: the screw air compressor has no unbalanced inertia force, the machine can work smoothly at high speed, can achieve foundation-free operation, especially suitable for use as a mobile compressor, small size, light weight, and small footprint.

4. Strong adaptability: the screw air compressor has the characteristics of forced gas transmission, the exhaust volume is almost not affected by the exhaust pressure, the operation is stable, the vibration is small, the exhaust is stable, and the high efficiency can be maintained in a wide range.

5. Multi-phase mixed transportation: there is actually a gap between the rotor tooth surfaces of the screw air compressor, so it can resist liquid impact, and can pressurize liquid-containing gases, dust-containing gases, and easily polymerized gases.

6. The unit exhaust volume is small, saving floor space.

Although the screw compressor has the above advantages, it is necessary to develop a detailed maintenance plan to keep the screw compressor unit running normally, safe and reliable, and have a long working life. It is best to carry out fixed-person operation, regular maintenance, and regular inspection and maintenance to keep the compressor clean, oil-free, and dirt-free. Only by fully mastering the common sense of maintenance and being familiar with the solution of faults can the smooth operation of the compressor be ensured.

The sliding vane air compressor is so troublesome when loading and unloading, it is oblong, the center of gravity is unstable, and I personally experience. Hehe!

Sliding vane air compressor is a positive displacement compressor, compared with the piston air compressor, it does not have a suction and exhaust valve and crankshaft connecting rod structure, therefore, the speed can be higher (<=300rpm) can be directly connected to the original motor, simple structure, easy to manufacture, easy to operate and maintain, the price is also cheap, at the same time, because the sliding vane air compressor mainly belongs to the rotary volumetric compressor, so, it works relatively calmly, the vibration is small, there is no complicated program. And because the rotation speed is high, the air supply is continuous, so the air flow pulse is small. Therefore, before the maturity and popularization of oil-injected screw air compressor technology, the piston air compressor was almost replaced by a sliding vane air compressor on the mobile air compressor used for power.
