The improper pressure adjustment of the hydraulic system of the liquid ring vacuum pump results in the heating of the system. The hydraulic system is generally a high pressure and large flow system. The programmable controller introduces Roots 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 the concrete cylinder at normal speed after the normal operation of each system. The piston of the concrete cylinder should keep running at the maximum stroke so as to give full play to the maximum efficiency of Roots vacuum pump and make the wear of the concrete cylinder even in the long direction. If the pressure is too high and unstable, the oil temperature rises. 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. From the investigation of the use of fine stone concrete pumps,
For many types of 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 high 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, so as to ensure the system regulation. Work under pressure. You can first hit the conveyor pipe with a mallet to get the elbow.
For the hydraulic system of the liquid ring vacuum pump, I believe that after you know about it, it will be more beneficial to us in the future. I hope that the above knowledge will help you.
