Advantages and Disadvantages of Vacuum Pump System



Compared with other types of mechanical vacuum pumps, the vacuum system water ring pump has the following advantages:
The structure is simple, the manufacturing accuracy is not high, and it is easy to process.
Compact structure, high pump speed, generally can be directly connected with the motor, without deceleration device. Therefore, with a small structure size, we can get a large amount of exhaust gas and occupy a small area.
Compressed gas is basically isothermal, that is, the temperature change of the compressed gas process is very small.
Because there is no metal friction surface in the pump chamber, there is no need to lubricate the pump, and the wear is very small. The sealing between the rotating part and the fixing part can be accomplished directly by the water seal.
Inhalation uniformity, stable and reliable work, simple operation, easy maintenance.
Water ring vacuum pump also has its shortcomings: low efficiency and low vacuum.
In short, because the gas compression in the water ring vacuum pump is isothermal, it can extract flammable and explosive gases. Due to the absence of exhaust valves and friction surfaces, dust-laden gases, condensable gases and gas-water mixtures can be removed. With these outstanding characteristics, it has been widely used in spite of its low efficiency.

Reasons for Axis Breakage of Water Ring Vacuum Pump and Corresponding Measures

Axis Breakage of Water Ring Vacuum Pump: After 2 years of use, water ring vacuum pump will present the phenomenon of excessive noise, excessive starting current, remarkable decrease in pumping capacity and vacuum degree. It is found that the scale inside the pump body is severe after the technical staff of our company disassembled and inspected. The reason for scaling is that the water contains calcium, magnesium and other carbonate substances. When the pump is heated and heated, its solubility decreases, and molecule-bound deposits form scales. What measures should be adopted to avoid axle breakage? Water ring vacuum pump Through the analysis of the causes of shaft breakage of water ring pump, the following corresponding measures are adopted. 1. Revamping the original process equipment to reduce the content of impurities in acetylene gas trap: At the same time, the large well water of water ring vacuum pump is changed into circulating water to reduce the hardness of wat
