Abstract

The invention belongs to a motor pump, and particularly discloses a motor pump for a hydraulic system. The motor pump comprises a plunger pump assembly, a motor assembly and a rotary transformer assembly, and the two ends of the motor assembly are fixedly connected with the plunger pump assembly and the rotary transformed assembly respectively. The design that high integration of a brushless motor and a plunger pump is adopted in the motor pump, the structure space is effectively reduced, and the motor pump is small in size, low in weight, compact in structure and high in sealing reliability.

Description

technical field [0001] The invention belongs to a motor pump, in particular to a highly integrated motor pump used in a hydraulic system. Background technique [0002] The power components in the current hydraulic system often use a single motor and a plunger pump, and the motor drives the plunger pump to output hydraulic energy. Both the motor and the plunger pump are separate products and can be tested individually. The plunger pump contains a mechanical seal mechanism, which is difficult to achieve zero leakage during operation and standing still, and cannot meet the requirements of long-term storage. Contents of the invention [0003] The purpose of the present invention is to provide an integrated motor pump for hydraulic system, which adopts the integrated design of brushless motor and plunger pump, which effectively reduces the structural space, is small in size, light in weight and compact in structure. High sealing reliability. [0004] Technical solution to ac...
