Optional combination parts maintenance In the process of manufacturing hydraulic valves, in order to make the assembly accuracy effective, most of the selection methods are selected, that is, for a batch of finished parts, such as the valve core and...

Hydraulic valves are an important part of hydraulic equipment and have an irreplaceable role in the use of hydraulic equipment. In the actual use of hydraulic equipment, once the hydraulic valve fails, it will directly lead to the equipment being...

The fuel injection pump is mainly used in diesel engines and some chemical equipment. At present, China's diesel engines can not meet the emission requirements stably. There are two main reasons: First, the diesel engine itself has low technical content,...

4Fracture analysis method of centrifugal oil pump Firstly, the centrifugal oil pump failure analysis should first read the relevant knowledge books, understand the structure and principle of the oil pump, increase the understanding of the equipment,...

The oil pump is a vital equipment for the production of each enterprise, especially related to the production safety of the enterprise and whether the economy can operate normally. Therefore, the relevant staff and management personnel must pay...

This paper optimizes the blade wear problem of a vane pump. The vane pump uses the blade and the slider, the positioning ring and the inner rotor core to realize the pumping and draining function of the vane. Because the vane and the slider are in direct...

In order to fully alleviate the impact hazard of gear pump oil trapping from the design, the new trapped oil flow multiplied by the trapped oil area is minimized as the design goal, and an optimization model based on the trapped oil performance is...

As an important control element in the hydraulic system , the hydraulic valve is responsible for the control function of the entire system. With the development of sensor technology and electronic technology, digital valves have received...

application High-pressure and low-energy consumption is a major feature of modern industrial products--the wide application of hydraulic transmission and control technology; high-speed, high-pressure, low-noise hydraulic pumps are necessary for the...

Through the research on the gear curve and the structure of the helical gear pump, the tooth profile curve and the helix angle of the gear pump gear are designed based on the original gear pump structure. The smooth transmission of the gear can be...
