SK Liquid Ring Vacuum Pump Hydraulic System

For SK liquid ring vacuum pump knowledge I believe you have a detailed understanding, but for its hydraulic system may be very strange, the following is to reveal the hydraulic system of SK vacuum pump:


SK liquid ring vacuum pump hydraulic system pressure adjustment is inappropriate, resulting in system heating, hydraulic system is generally high pressure and large flow system. The programmable controller introduces Roots SK liquid ring vacuum pump, which greatly improves the reliability of electrical system. At the same time, we should observe the pressure and the working conditions of each system, and pump at normal speed after the normal operation of each system. The vacuum pumping of SK liquid ring should be carried out as continuously as possible. The piston of concrete cylinder should keep running at the maximum stroke so as to give full play to the maximum efficiency of Roots SK liquid ring vacuum pump, and make the wear of concrete cylinder uniform in the long direction, if the pressure is too high and not. Stable and oil temperature increased. When the open crown vibration of the conveyor pipe and the difficulty of pumping are encountered, the forced pumping shall not be allowed, and the causes shall be immediately ascertained and eliminated. It was found from the investigation of the use of fine stone concrete pump.


For many types of SK liquid ring vacuum pumps, the temperature of the hydraulic system can be as high as 60E after 40 minutes of use. After about 2 hours of use, the thermal equilibrium temperature of the hydraulic system can be as high as 70e, while the normal thermal equilibrium temperature of the hydraulic system should be about 50e. Therefore, the problem of excessive oil temperature in hydraulic system, i.e. heating, has arisen. In hydraulic system, due to performance requirements, safety valve, relief valve and sequential valve are often installed in the system. If the pressure of the safety valve is too low, the safety valve will be opened frequently, resulting in overflow loss and system heating; if the pressure is too high, it will increase the leakage in the system and make the system heating. Therefore, according to the load requirements of the hydraulic system, the safety valve and pressure value should be calculated and adjusted correctly to ensure that the system works within the prescribed pressure range. You can first hit the conveyor pipe with a mallet to get the elbow.
