Liquid ring compressor for sugar industry
Liquid ring compressor used in sugar industry is widely used in petrochemical industry, pharmaceutical industry, food industry, sugar industry and other fields. Because the compression process of gas in the working process is isothermal, so it is not easy to be dangerous when compression and suction flammable and explosive gas, its application is more extensive.
Liquid ring compressor for sugar industry of working principle
When the impeller turns against the market direction, the water is thrown around the impeller, because of the centrifugal force, the water formed a decision on the shape of the pump chamber is approximately equal thickness of the closed ring. The lower part of the inner surface of the liquid ring is exactly tangent to the impeller wheel box, and the upper part of the inner surface of the liquid ring is just in contact with the top of the blade (actually, the blade has a certain depth of insertion in the liquid ring). At this time, a crescent space is formed between the impeller shell and the inner interface of the liquid ring. If starting point is the bottom of the impeller 0 ℃, so in front of the rotating impeller 180 ℃ when the small cavity volume changes from small to big, and with suction mouth on the face, the gas is inhaled, when the suction at the end of the small cavity is isolated from the rest of inspiratory mouth, when the impeller to rotate, small cavity from large to small, make the gas is compressed, when small cavity with vent gas is expelled outside pump.
Liquid ring compressor for sugar industry of main advantages
1) compressed gas is basically isothermal, that is, the compressed gas has little temperature change.
2) simple mechanism, low manufacturing accuracy requirement, easy to process.
3) since there is no metal friction surface in the vacuum pump cavity, there is no need to lubricate the pump, and the wear is very small, the sealing between rotating parts and fixed parts can be completed directly by water seal.
4) uniform suction, stable and reliable work, simple operation and convenient maintenance.
5) compact structure, high rotation of vacuum pump, generally can be directly connected with the motor, no reduction device is needed, so the small size of the structure can achieve large exhaust volume, small area.
6) machine pump coaxial direct connection design, easy to install, save space;
7) unified corrosion resistance design, bronze impeller improves the corrosion resistance of the pump, stainless steel material is more suitable for more demanding working environment;
8) unique flexible exhaust port design, does not produce over-compression, ensuring that 2BV has a good zui efficiency within its performance range.
9) mechanical seal is adopted as standard configuration, eliminating leakage and easy maintenance;
10) smooth operation, noise can be as low as 62 db.
