    Specific starting steps of gear pump

    The specific starting steps of gear pump are as follows: 1. Rotate the gear pump coupling by hand, it should feel light and evenly stressed. 2. Check whether the rotation direction of the pump is correct, which should be consistent with the direction indicated by the label on the pump body. If there is no special requirement, the general gear pump station is left in and right out when viewed from the motor end. 3. Check whether the hydraulic system has unloading circuit to prevent full load star... Read More

    Selection guide of gear oil pump

    Gear oil pump is also called positive displacement device in terminology, that is, like a piston in a cylinder, when one tooth enters the fluid space of another tooth, the liquid will be mechanically squeezed out. Because the liquid is incompressible, the liquid and the tooth cannot occupy the same space at the same time, so the liquid will be excluded. Because the teeth are continuously meshed, this phenomenon will happen continuously, Therefore, a continuous discharge quantity is provided at t... Read More

    Specific calculation method of flow and displacement of gear pump

    The gear pump can be divided into two types: external engagement and internal engagement. The external engagement gear pump has several kinds of gears, such as straight teeth, helical teeth and human teeth. Generally, the involute profile is adopted, while the internal engagement gear pump adopts arc cycloid profile or involute profile Gear pump engagement classification The number of gears in the external gear pump is two gears in common use, and there is only one gear in the internal gear pump...
