Problems solved by technology

However, due to the poor pollution resistance of the hydraulic pump of the servo valve control system, the cost is high, and the use and maintenance costs are extremely high
At present, most of the hydraulic pumps of the servo valve control system and the hydraulic pump of the proportional valve control system are expensive to use and are monopolized by foreign technology, which has become a bottleneck in batch use. At the same time, the energy saving of hydraulic transmission is greatly hindered.

Abstract

The invention relates to a servo control structure of a hydraulic pump. The servo control structure comprises a servo control module connected with a pump module (1) of the hydraulic pump. The servo control structure is characterized by further comprising a control oil source module (2) connected with the servo control module; and the servo control module is a jet pipe servo control module (3). Compared with the prior art, the servo control structure has the beneficial effects that the jet pipe servo control module is used for controlling the hydraulic pump, the anti-pollution capability and control precision are high, the production cost is reduced, using and maintaining are easy and convenient, and large-scale production and usage are convenient.

Description

technical field [0001] The invention relates to a hydraulic pump servo control structure. Background technique [0002] Hydraulic transmission is widely used in modern machinery due to its advantages such as high power density, flexible and convenient layout, simple structure, wide range of speed regulation, and simple manufacture, use and maintenance. Hydraulic pump is the core power source in hydraulic transmission, and its energy-saving performance directly affects the entire hydraulic system. Therefore, improving the effective power of hydraulic transmission is the focus of major research at home and abroad. [0003] At present, the energy-saving effect of the hydraulic pump of the servo valve control system and the proportional valve control system is the most prominent. However, due to the poor pollution resistance of the hydraulic pump of the servo valve control system, the cost is high, and the use and maintenance costs are extremely high. At present, most of the h...
