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 startup... Read More

Selection principle of industrial pump
1、 The type and performance of the selected pump meet the requirements of process parameters such as unit flow, head, pressure, temperature, medium viscosity, NPSH, suction head, etc.2、 It must meet the requirements of medium characteristics.1. For pumps conveying inflammable, explosive, toxic or valuable media, the shaft seal shall be reliable or leakage free pumps shall be used, such as magnetic drive pump, diaphragm pump and shield pump.2. For pumps conveying corrosive media, it is required t... 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 profileGear pump engagement classificationThe 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. ...

What is double hydraulic pump
Double hydraulic pump, the same transmission shaft drives the rotors of two pumps to rotate, which are connected and driven by a motor. The suction port of the pump is public, and the pressure ports are separated. The two flows output by the pump can be used separately or in parallel. Hydraulic transmission is a kind of hydraulic component that provides pressurized liquid and a kind of pump. Its function is to convert the mechanical energy of power machine (such as motor and internal combustion ... Read More

How to avoid power loss of hydraulic system
On the one hand, the power of the hydraulic system will cause the loss of energy and reduce the overall efficiency of the system. On the other hand, the lost energy will be converted into heat energy, which will increase the temperature of the hydraulic oil and deteriorate the oil, resulting in the failure of the hydraulic equipment. Therefore, in the design of the hydraulic system, on the premise of meeting the use requirements, we should also fully consider reducing the power loss of the syste... Read More

Brief introduction and classification of hydraulic pump and hydraulic components
A brief introduction of hydraulic pumpIt is a kind of hydraulic component that supplies pressurized liquid for hydraulic transmission and a kind of pump. Its effect is to convert the machine energy of power machine (such as electric motor and internal combustion engine) into the pressure energy of liquid. The output flow can be adjusted if necessary, which is called variable pump. If the flow of wiggs accessories cannot be adjusted, it is called quantitative pump. There are three kinds of pumps ...
