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
High pressure hydraulic gear pump and common gear pump have the following differences: (1) The shape of the high pressure hydraulic gear pump is rectangle five piece combined type, which is easy to process, neat and beautiful; (2) The noise of high pressure hydraulic gear pump is low, and the noise value under maximum load can reach a level of product standard (ordinary gear pump is generally at B and C level); (3) The volume efficiency of high-pressure hydraulic gear pump can reach 95%, which b...

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
The difference between internal gear pump and external gear pump is: different composition, different principle and different leakage. 1、 Different composition 1. Internal gear pump: the internal gear pump is composed of a pair of internal gears which mesh with each other, crescent shaped parts and pump shell in the middle. 2. External gear pump: external gear pump is composed of external driving gear, driven gear, pump body, pump cover and safety valve. 2、 Different principles 1. Internal gear ... Read More
