The engine, hydraulic pump, and distribution valve are the three major parts of excavators that people often say. For Xiaobai who first came into contact with excavators, they must be wondering why the excavator is not powered by an engine like a car. The drive shaft drives the vehicle forward but drives the hydraulic pump…
How to analyze the failure of the vane pump control valve? The fuel is supplied by the main fuel pump, and the fuel bypass valve of the main fuel pump adjusts the fuel quantity of the unit, thereby controlling the change of the load. So how to analyze the failure of the vane pump control…
Removal steps and installation instructions of hydraulic motor: How to Remove and Install a Hydraulic Motor? Under normal circumstances, do not disassemble the motor at will, and only when it has a serious failure can it be disassembled for inspection. Preparations for dismantling the hydraulic motor Remove the oil drain plug and drain the oil…
9 precautions for hydraulic pump cooling, we’ve sorted out the following 9 points to pay attention to when it comes to hydraulic pump cooling: Using oil to cool hydraulic pumps and motors To cool the hydraulic pump and motor, it is occasionally essential to fill the hydraulic pump and motor with oil. However, keep in…
What are the functions of hydraulic pumps? It includes hydraulic pump oil suction, oil pressure, and hydraulic pump oil volume adjustment. Let me tell you about these aspects: Hydraulic pump suction and pressure oil The reciprocating action of the plunger in the plunger sleeve completes the oil suction and oil pressure of the jet hydraulic…
Analysis and Solution of Serious Wear Problem of Plunger Pump of Wheel Loader
The tip of the Rexroth vane pump is near the inner surface of the stator when the rotor of the Rexroth vane pump spins under the influence of centrifugal force and pressure oil. The working volume produced by the two blades and the inner surface of the rotor and stator receives oil from small to…
How may hydraulic equipment’s power loss be reduced?
As the energy device of the hydraulic system, the hydraulic pump occupies a very important position in the hydraulic system. If the hydraulic pump fails, it will affect the normal operation of the entire hydraulic system. The oil pump cannot suck up the oil The inlet and outlet ports are connected reversely. Elimination method: select…
The methods for judging the failure of an excavator’s hydraulic pump can be divided into two categories: instrument diagnosis and manual diagnosis. A physical test is used to diagnose an instrument. The hydraulic pump’s technical state and problems are initially diagnosed using the manual diagnosis method, which employs vision, touch, smell, and hearing. The following…
