  • What is the main function of gear pump valve

    What is the main function of gear pump valve

    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

  • How to deal with sudden power failure of magnetic gear pump in operation?

    How to deal with sudden power failure of magnetic gear pump in operation?

    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 t...

  • What are the precautions for construction of hydraulic gear pump?

    What are the precautions for construction of hydraulic gear pump?

    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 reason why the self-priming centrifugal pump can't suck oil and the solution

    The reason why the self-priming centrifugal pump can't suck oil and the solution

    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 underst...

    What pump is used to deliver high viscosity liquid?

    Screw pumps or high viscosity pumps shall be used. Screw pump: the screw pump is a positive displacement rotor pump, which sucks and discharges the liquid by the volume change of the sealing cavity formed by the screw and the bush. The screw pump is characterized by stable flow, small pressure fluctuation, self-priming capacity, low noise, high efficiency, long life and reliable operation. Its outstanding advantages are that it does not form eddy current when conveying medium, is not sensitive t... Read More

    Performance analysis of gear pump

    Stainless steel gear pump is a kind of pump product which is connected with motor and works under the liquid at the same time. Compared with ordinary gear pump or asphalt pump, stainless steel gear pump has the following advantages:1. The structure is compact and the air volume is small. The stainless steel pump can be directly installed in the sewage tank because it works under the liquid. There is no need to build a special pump house to install pumps and machines, which can save a lot of land... Read More
