In the normal operation of construction machinery, the hydraulic system is usually used for motion control, and the hydraulic system needs a certain power system to transfer liquid. In actual production, this power system usually uses a plunger pump and a gear pump.

The choice of gear pump and plunger pump needs to be selected according to the actual situation of the project (such as: the function of the equipment, the requirements of the hydraulic system, the control of manufacturing costs, the working environment of the equipment, etc.), not only the equipment The needs of the environment must also take into account the needs of the environment and maintenance costs. Gear pumps and plunger pumps have different advantages and disadvantages, and can even be interchanged under specific conditions. Therefore, designers are designing engineering machinery. When choosing a pump, if the gear pump can meet the requirements after certain improvements, the gear pump should be selected first. Try not to use the plunger pump with high requirements on the environment, liquid filtration and maintenance.
