1、 The composition is different Gear pump: gear pump is composed of pump body, driving gear, passive gear, bearing, oil seal and gear shaft. Hydraulic gear motor: the hydraulic gear motor is composed of shell, crankshaft, port shaft, connecting rod, plunger and eccentric wheel. 2、 The working principle is different Gear pump: the working principle of gear pump is to transfer liquid or pressurize it by changing and moving the working volume formed between pump cylinder and meshing gear. Hydraulic... Read More
If the hydraulic oil pump fails, it will affect the work of the whole system. Today, we will introduce 10 causes of hydraulic pump failure. Coupling installation error Because the fit clearance between coupling and shaft is too small or no clearance, the bearing will be injured when it is knocked hard, which will lead to early damage of the bearing and affect the life of the whole pump core. Coaxiality out of tolerance If the concentricity exceeds the specified value during installation, the bea... Read More
Strengthening the maintenance of the equipment is very important to ensure the normal operation of the equipment. At present, there are four problems in hydraulic equipment 1. The hydraulic system works well and sometimes fails, and the actuator sometimes does not work; 2. Serious system leakage; 3. The actuator has jumping, vibration or crawling when it moves; 4. The temperature rise of working oil in hydraulic system is too high. If the above four problems are analyzed and diagnosed to find ou... Read More
1、 Brief introduction: Dump truck is a vehicle that unloads goods by hydraulic or mechanical lifting. Also known as dumper. It is composed of automobile chassis, hydraulic lifting mechanism, cargo box and power take-off device. 2、 Application scope of dump truck In civil engineering, dump truck often works with excavators, loaders, belt conveyors and other construction machinery to form a loading, transporting and unloading production line for loading, unloading and transportation of earthwork, ...

Almost all the causes of the failure of "vane pump can not produce oil" may be the reason that the pressure can not go up or there is no pressure at all 1. There is poor contact between the oil distribution plate and the end face (fixed surface) of the housing, and there is a large dirt between them, so that part of the pressure oil in the pressure oil chamber flows into the low-pressure area through the gap between them, and the output flow is reduced. Therefore, it should be disassembled and c... Read More
