The main function of the gear pump valve is to prevent the gear pump motor from burning or damaging the pipeline equipment caused by the gear pump outlet pipe blockage or the gear pump outlet pressure being too high. The choice of gear pump is to calculate the required gear pump outlet pressure, that is, we often say the head of gear pump. According to the actual working pressure of gear pump, medium viscosity and medium specific weight, the actual working pressure of gear pump is measured. In t... Read More
In the use process of magnetic gear pump, if the power supply is suddenly blocked or suddenly cut off, if there is no correct operation, the equipment itself will form great harm. Pumps and prime movers generally require very small moments of inertia. As a result, the pump will stop quickly and steeply. At the moment, unless the pipeline is very short, the inertia of the liquid will still make the liquid stop move forward forcefully, while the deceleration stainless steel magnetic gear pump has ...

During the installation of the hydraulic gear pump, the safety valve and remote device must be set, and the oil tank must be dustproof to prevent mud, sand and other debris from entering the oil and cleaning regularly. The oil suction pipe should be as short as possible, generally no more than 500mm, and should be as far as possible. Use fewer elbows, and the oil pipe shall not leak. 1. The working oil shall be kept clean. It is recommended to install an oil filter with a filtering accuracy of 8... Read More
The big advantage of self-priming centrifugal pump is that it can self-priming, which is different from the operation of other pumps. In the secondary use, just fill the water in the self-priming centrifugal pump, and then start up. In the future, there is no need to inject water every time. The principle is very simple, the impeller in the pump rotates, the vacuum is formed in the pump shell, and the water pressure is put into the pump by atmospheric pressure to form a circulation. After unders... Read More
The assembly method of mechanical seal of screw pump and three screw pump is very important. The correct assembly method can ensure that the seal of screw pump and three screw pump will not leak. The specific installation and use methods are as follows: 1. Check whether the model and specification of the mechanical seal for screw pump and three screw pump are correct. 2. Check whether the dimensional accuracy, geometric accuracy and interrelation of the parts related to the installation of screw... Read More
