Excavator hydraulic pump structure and main functions

　　We need to master some theoretical knowledge of excavators when using excavators. In addition to understanding excavator equipment, we can eliminate the causes of failures such as shutdowns in daily use as soon as possible. Some users with strong hands-on ability can even solve the problem by themselves. The price of excavator hydraulic pumps is high, and not all problems are replaced. Checking the cause of the failure and replacing it with spare parts can save users a lot of expenses. Of course, for Mini excavators, 1-2 people can completely repair and replace the hydraulic pump by themselves, but in medium and large excavators, professional technicians and professional tools must be used to avoid personal injury.First, let me introduce the key structures of hydraulic pumps

　　1. Drive shaft appetite hydraulic pump approved power transmission components, mainly used to connect excavator engines or pure electric excavator motors. The structure is simple and the failure rate is low.

　　2. In addition to protecting the internal structural components, the outer shell of the excavator pump body forms a hydraulic oil channel with a simple structure and a low failure rate.

　　3. The oil distribution plate mainly controls the flow of hydraulic oil by changing the direction of hydraulic oil in and out.

　　4. Plunger, gear, blades These are also the internal metal components that are most prone to failure in the hydraulic pump. The quality, temperature, dust and foreign matter of the hydraulic oil will cause wear of the internal structural parts. The failure rate varies from person to person. Paying attention to maintenance and a good working environment can avoid or reduce the failure rate.

　　5. The distribution plate is mainly used to control the inlet and outlet and flow direction of the hydraulic oil, and the oil can flow smoothly between the high and low pressure areas.

　　6. Suction port/discharge port: The hydraulic oil can enter the pump body through the suction port and then flow out through the discharge port after pressurization.

　　7. Hydraulic regulator This can be adjusted through manual intervention during use, but for individual users, it is not necessary to operate under the guidance of professionals. Improper flow control will shorten the life of the hydraulic pump or cause the excavator to be powerless. Control the output pressure of the pump to ensure the stability and safety of the hydraulic system.

　　The hydraulic pump is one of the core components of the more precise engine. At present, there are many well-known hydraulic pump manufacturers in the world. Excavator manufacturers adjust the hydraulic pump and engine when manufacturing excavators. If a fault occurs later, they should be replaced as much as possible. The same model should be selected for replacement.

　　Tiedou provides hydraulic pump assemblies for excavators of various brands and models. In addition to original hydraulic pumps, users can freely choose new hydraulic pumps and second-hand hydraulic pumps. It also provides hydraulic pump parts. The equipment failure and shutdown of the excavator and the design of hydraulic system problems are not entirely caused by the hydraulic system. The hydraulic pipelines, distribution valves, and control systems all need to be checked in detail before the hydraulic pump can be disassembled. The internal structure of the hydraulic system is tight and the installation requirements of metal parts are extremely high. Once dismantled and repaired, the service life and performance cannot be guaranteed. In daily use, observe the hydraulic oil, hydraulic oil filtration, hydraulic cylinder seals, hydraulic pipelines, and connection sealing during use to reduce dust and foreign matter from penetrating into the hydraulic oil.
