Problems solved by technology

In addition, the motor connected to the vane pump generally contains a cooling fan, so the noise of the entire hydraulic power unit is also very large; at the same time, because the vane pump has an overhanging shaft, there is an external leakage path
General hydraulic pumps have the problem of insufficient oil absorption to varying degrees. Therefore, an auxiliary pump needs to be installed at the oil suction port of the main pump to improve the oil absorption capacity of the main pump. The auxiliary pump is generally an independent hydraulic pump and needs to be driven by a separate motor. The whole hydraulic power unit is relatively complex and bulky

Abstract

The present invention provides a motor embedded lamina pump. The motor rotor (22) is supported in a sliding bearing (5) in a right flow distribution cover (33) and a rolling bearing (5) in a pump cover (7) by a motor rotor sleeve (23), a first spline (3a) and a principle axis (3). A pump rotor (35) connects with the principle axis (3) and distributes equally main laminas (31) and sub-laminas (32), outside of the pump rotor (35) has a pump stator (39) which is mounted in a pump center seat (25) with a left flow distribution cover (37), the right flow distribution cover (33) by orientation pins (38) and a press cover (29), a motor stator (21) is provided pressed in the pump hull (24). The motor embedded lamina pump integrates driving motor, high pressure sub-main type lamina pump, centrifugal auxiliary pump in structure, has merits of mute, compact structure, high efficiency, convenient cooling and no leakage.

Description

Technical field [0001] The invention relates to a vane pump, in particular to a vane pump with a motor built-in. Background technique [0002] The vane pump is a structural form of the hydraulic pump, which has the advantages of good flow uniformity and low noise, so it has been widely used. At present, as an independent hydraulic power component, the vane pump needs to be connected to an independent electric motor or internal combustion engine through its extended pump shaft to form a motor-hydraulic pump unit to form a hydraulic power unit to work. This connection requires a coupling, a pump frame, etc. The device, due to the large volume of the independent electric motor, coupled with the coupling and other accessories, the volume and weight of the entire hydraulic power unit is very large. In addition, the motor connected to the vane pump generally contains a cooling fan, so the entire hydraulic power unit is also very noisy; at the same time, because the vane pump has an ext...
