Description
Technical field
This utility model belongs to technical field of hydraulic pressure, particularly relates to a kind of Ultra-high Pressure Radial Piston Pump containing composite self-lubricating bearing.
Background technology
At present, what the spring bearing of the rotating shaft of Ultra-high Pressure Radial Piston Pump generally assembled is rolling bearing, and the shortcoming of prior art is that rolling bearing bearing capacity is little, the life-span compared with short, noise is big, cost is high.
Summary of the invention
In order to overcome rolling bearing bearing capacity little, the life-span, compared with shortcoming short, that noise is big, cost is high, we have proposed a kind of Ultra-high Pressure Radial Piston Pump containing composite self-lubricating bearing.It is good that the present invention employs anti-wear performance on Ultra-high Pressure Radial Piston Pump, and coefficient of friction is little, service life length and compact conformation, mechanical strength is high, the composite self-lubricating bearing that noise is low.
nullThis utility model solves its technical problem and be the technical scheme is that a kind of Ultra-high Pressure Radial Piston Pump containing composite self-lubricating bearing，Including pump housing upper plate、Upper composite self-lubricating bearing、Mandrel、Eccentric block、Pin、Oil outlet one-way valve、In line check valve、Assembly for plunger、Pump housing lower plate、Set、Lower composite self-lubricating bearing、Flat key、Eccentric bushing、Rolling bearing、Soket head cap screw，Pump housing upper plate machined the oil circuit connecting each plunger，It is connected with the oil-out of assembly for plunger，Upper composite self-lubricating bearing shares the thrust of assembly for plunger together with lower composite self-lubricating bearing，Mandrel is the core of plunger displacement pump rotary motion，By the rotation of mandrel，Assembly for plunger is promoted to complete suction oil action，Eccentric block plays pump housing balanced action，Reduce vibration，Bias is cased with certain offset，Decide the suction oil ability of assembly for plunger，And then determine the flow of plunger displacement pump，Rolling bearing can reduce the normal direction resistance when mandrel equipped with eccentric bushing rotates suffered by plunger.
The beneficial effects of the utility model are: this Ultra-high Pressure Radial Piston Pump design compact conformation containing composite self-lubricating bearing is reasonable, and composite self-lubricating bearing anti-wear performance is good, and coefficient of friction is little, and service life is long.Plunger displacement pump can bear bigger steady load and dynamic loading.Alleviate the vibration of plunger displacement pump, reduce noise.
