SZB Series Liquid Ring Vacuum Pump for Vacuum Degasser
1, Product overview:
SZB water ring vacuum pump is used to pump or compress air and other non corrosive, water insoluble and solid particle free gases. The maximum vacuum degree of non corrosive gases can reach 85%, so as to form vacuum and pressure in closed containers. However, the inhaled gas can be mixed with a small amount of liquid. It is widely used in machinery, petrochemical, pharmaceutical, food, sugar industry and electronic fields. Because the gas compression is isothermal in the working process, it is not easy to cause danger when compressing and pumping flammable and explosive gases, so it is more widely used.
SZB water ring vacuum pump is a suspended water ring vacuum pump, which can be used to pump air or other non corrosive, water insoluble and solid particle free gases. The minimum suction pressure is -0.086MPa. It is widely used in machinery, petroleum, chemical, pharmaceutical, food and other industries and other fields, especially suitable for large water pumps in temples.
2, Scope of application:
SZB water ring vacuum pump is widely used in machinery, petrochemical, pharmaceutical, food, sugar industry and electronic fields, especially for large water pumps.
3, Working principle:
SZB water ring vacuum pump realizes suction, compression and exhaust by changing the volume of pump chamber, so it belongs to variable volume vacuum pump. The impeller is eccentrically installed in the pump body. When the impeller rotates, the water entering the water ring pump body is thrown around by the impeller. Due to the centrifugal force, the water forms a closed water ring of equal thickness similar to the shape of the pump chamber. Water ring The upper inner surface is just tangent to the impeller hub, and the lower inner surface of the water ring is just in contact with the top of the blade. At this time, a crescent shaped space is formed between the impeller hub and the water ring, and this space is divided into several small cavities equal to the number of blades by the impeller. If the upper 0 ° of the impeller is taken as the starting point, then when the impeller rotates 180 ° before, the volume of the small chamber gradually increases, the pressure continuously decreases, and it is connected with the suction port on the suction and exhaust disks. When the pressure in the small chamber space is lower than the pressure in the pumped container, according to the principle of gas pressure balance, the pumped gas is constantly pumped into the small chamber, which is in the process of inspiration. When the suction is completed, it is isolated from the suction port. From section 1-11 to section 1-1I1, the volume of the small chamber is gradually decreasing, and the pressure is constantly increasing. At this time, it is in the process of compression. When the compressed gas reaches
Bleed the air early from the auxiliary exhaust valve when the exhaust pressure is high. From section 1 to 1-1, the volume of the small cavity connected with the exhaust port further reduces and the pressure further increases. When the pressure of the gas is greater than the exhaust pressure, the compressed gas is discharged from the exhaust port. During the continuous operation of the pump, the suction, compression and exhaust processes are carried out continuously, so as to achieve the purpose of continuous air extraction.
5, Product features:
1. Simple structure, low manufacturing precision requirements, easy processing.
2. Compact structure, high rotation rate of the pump, it can be directly connected with the motor, and no reducer is required. Therefore, with small structure size, large exhaust volume can be obtained and the floor area is small.
3. Compressed gas is basically isothermal, that is, the temperature change of compressed gas is very small.
4. Since there is no metal friction surface in the pump cavity, there is no need to lubricate the pump, and the wear is very small. The sealing between the rotating part and the fixed part can be directly completed by the water seal.
5. The suction is uniform, the work is stable and reliable, the operation is simple, and the maintenance is convenient.
