Excavator Main Pump

The hydraulic system of the excavator is a combination that organically connects various hydraulic components with pipelines in accordance with the transmission requirements of the working device of the excavator and each mechanism. It mainly includes hydraulic oil tank, main pump, multi-way valve, each pipeline and cylinder, motor and other components that perform each action. Its function is to use oil as the working medium, use the hydraulic pump to convert the mechanical energy of the engine into hydraulic energy and transmit it, and then convert the hydraulic energy into mechanical energy through the hydraulic cylinder and hydraulic motor to realize various actions of the excavator. At present, the main pump of the excavator mainly uses a plunger pump, and its pumping mechanism is exactly the same as that of the syringe to drain liquid.

The quality of the main pump of the excavator determines the efficiency of its working operation. Therefore, it is extremely important to choose a master pump of the highest quality. Xiaobian recommends a cost-effective hydraulic pump for everyone. That is the Elephant Fluid Power's A4VSO355LR2G/30R-PPB13N00 hydraulic piston pump. Its application fields are building materials equipment, iron and steel metallurgy, hydraulic systems and other high-speed and high-reliability applications. Designed for open circuit hydraulic drive, remote control. The flow rate of the pump is directly proportional to the speed and displacement of the pump, and the displacement can be infinitely adjusted by adjusting the inclination of its swash plate. Low noise, long life, modular design. The thru-shaft structure can be combined with a mounting position. Its five-piston structure, eccentric shaft, low excitation frequency, and low noise characteristics; Large starting torque and good stability at low speed; Flat compensation oil distributor, good reliability, no leakage; The piston and plunger sleeve are sealed with sealing rings, which has high volumetric efficiency; There is roller support between the crankshaft and the connecting rod, which has high mechanical efficiency; The direction of rotation is reversible, and the output shaft allows to withstand radial and axial external forces; The power quality ratio is high, the volume weight is small, and the noise is less than 80 decibels.  The reason for the production of such high-quality hydraulic components is inseparable from the excellent capabilities of the company itself. Elephant fluid power occupies a rich product advantage in China. There are professional suppliers in China that provide any metal parts needed in the manufacturing pump process. Therefore, the hydraulic pumps and accessories manufactured by Elephant Fluid Power have high precision and reasonable cost.
