Abstract

The invention discloses a multi-layer radial plunger micro-metering pump. The multi-layer radial plunger micro-metering pump comprises a power system, a pump body and a cam mechanism, the pump body comprises a cylinder body and three layers of plungers arranged on the cylinder body, two adjacent layers of plungers are corresponding, each layer comprises three plungers uniformly distributed along the radial direction of the cylinder body, the cam mechanism comprises a cam fixing plate and inner cams, three inner cams are arranged along the axial direction, and the angle between two adjacent inner cams is 120 degrees. The multi-layer radial plunger micro-metering pump is high in pressure, very low in flow rate, small in dead volume and capable of resisting leakage and realizing bidirectional transmission.

Description

technical field [0001] The invention belongs to the technical field of fluid conveying devices, in particular to a multilayer radial plunger micrometering pump. Background technique [0002] The fluid conveying device is a general-purpose machine for fluid conveying. Its function is to transfer the energy of the motor or other prime movers to the conveyed fluid to increase the energy level of the fluid (that is, the mechanical energy of the unit fluid). Hydraulic pumps It is a widely used fluid conveying device. The hydraulic pump is the energy provider of the hydraulic transmission system and belongs to the hydraulic power component. It mainly includes four categories: vane pump, gear pump, screw pump and plunger pump. The vane pump is affected by the stator curve and material, and the pressure should not be too high; the gear pump has a large oil pulsation, cannot be variable, the pump shaft is unbalanced, the wear is serious, the leakage is large, and it cannot be used in...
