Abstract

The utility model belongs to the plunger pump technology field, relates to a plunger oil less high pressure pump. Wherein, a plunger supercharging structure driven by a pump shaft, an eccentric ring, a bearing, a connecting rod, a plunger and a plunger sleeve is mounted in the pump body; the plunger supercharging structure is: at least two connecting rods are disposed on the pump main shaft parallelly coaxially with intervals; the connecting rods are fixed on the bearing; the bearing is disposed on an eccentric sleeve; the eccentric sleeve is fixed on the pump main shaft; the other end of the connecting rod is hinged with the plunger; the plunger is mounted inside the pump body cavity; a self-lubricating plunger sleeve is disposed between the pump body and the plunger; a water sealing ring and a gasket are disposed on the contact position of the plunger end and the pump head; The pump of the utility model achieves the advantages of simple structure, no pollution, high pressure, high efficiency and long service life; and can operate without any lubricating oil or grease.

Description

Plunger does not have the innage press pump

Technical field

The utility model belongs to the plunger pump technique field, refers in particular to a kind of plunger and does not have the innage press pump.

Background technique

Plunger pump has been widely applied every field such as industry, life at present, in each big city, all be applied to equipment such as a large amount of washing machines, atomizer, and the pump on the washing machine, atomizer is the critical component of entire equipment, and the quality of pump directly has influence on the utilization efficiency of entire equipment; The general high-pressure service pump that oil lubrication is arranged that adopts of pump on existing washing machine, the atomizer, a large amount of various lubricant oil or grease all will be used with lubrication in the pump head of this pump and pump housing inside, all to use lubricant oil and grease in the moving up and down of its pump housing inner plunger, this pump exists some deficiencys: 1, need two weeks to change once oil in the maintenance stage, the maintenance stage needed one month to change once oil later, and energy consumption is big; 2, the oil of Geng Huaning can cause to a certain degree pollution to environment; 3, seal request height, the driving mechanism of driven by motor is made of crankshaft-and-connecting-rod, and a plurality of connecting rods are inconvenient to install on bent axle, have improved to become to produce cost; 4, installation is improper causes leakage of oil to cause water pump to damage easily.

Summary of the invention

The purpose of this utility model provides a kind of simple in structure, pollution-free, high pressure, high efficiency, long service life, does not have the plunger that any lubricant oil or grease just can operate and does not have the innage press pump.

The purpose of this utility model is achieved in that

Plunger does not have the innage press pump, pump head is installed on the pump housing, the plunger booster body that is driven by the pump main shaft is installed in the pump housing, described plunger booster body is: have two connecting rods intervals and coaxial in parallel to each other being arranged on the pump main shaft at least, described connecting rod one end is located on the bearing, bearing is installed on the eccentric bushing, eccentric bushing is fixed on the pump main shaft, the other end and the plunger of connecting rod are hinged, plunger is installed in the cavity of the pump housing, between the pump housing and plunger, be provided with the selflubricating plunger bushing, be provided with water shutoff circle and pad in the end of plunger and the contacting point of pump head.

Above-mentioned connecting rod and plunger are hinged for the joint of plunger is provided with slot opening, are provided with bearing in the attachment hole of connecting rod, the connecting rod joint and on bearing stretch in the slot opening of plunger and link to each other by hinge bar.

Above-mentioned connecting rod, the plunger booster body that forms with the supporting plunger of connecting rod, selflubricating plunger bushing, water shutoff circle, pad and pump head have three covers.

Above-mentioned eccentric bushing is positioned on the pump main shaft by axle key.

Above-mentioned selflubricating plunger bushing is engineering plastics.

It is to be arranged with the collar at interval on the eccentric bushing between two adjacent connecting rods that above-mentioned connecting rod is disposed on the pump main shaft.

The outstanding compared to existing technology advantage of the utility model is:

1, the utility model with on the pump main shaft dress locating stud fixedly eccentric bushing replaced the bent axle transmission of multicolumn plug, be easy to the manufacturing, easy disassembly, cost of production is low.

2, the utility model is provided with the selflubricating plunger bushing in the contacting point of the pump housing and plunger, wear-resisting, high temperature resistant coupled columns is filled in the self-lubricated characteristics of row but the selflubricating plunger bushing has, making in the utility model pump housing need not various lubricant oil or grease, can make plunger motion freely, saved the energy, pollution-free again.

3, plunger booster body of the present utility model has three covers, drives with a pump main shaft, has improved the working efficiency of equipment.
