Abstract
The utility model discloses a water proof oil seal, comprising two seal rings ('U'-shaped oil seal) which are usually provided with skirt hems, and a hollow cavity full of viscous oil. By using the liquid incompressible principle, the utility model has the advantages of simple structure, good tightness and convenient installation, able to be used for liquid medium pumps.
Description
The utility model relates to a kind of waterproof axle envelope.
Though the water pump bearing structure is different, all uses oils as oiling agent mostly, enters bearing if any water; regular meeting makes deterioration of oil and damages bearing, and therefore, water pump must be isolated with water and bearing with the axle envelope; when working medium is corrosive liquids, then higher to the requirement of axle envelope.Leak because of water seal and to cause the problem of damage of bearings to happen occasionally.
For addressing this problem, common way is scurf resistance, the degree of finish that increases static and dynamic sealing spare in the axle envelope, but this method requires high material and stronger manufacturability, makes complex structure unavoidably, and price increases.
The purpose of this utility model provides a kind of high leak tightness, durable and simple in structure waterproof axle seals.
It is achieved in that between water pump vane and bearing two in device common shirt rim seal ring (" U " type oil sealing) arranged, between two oil sealings, fill with viscous oil again, exhausting air.When oil sealing 1 was subjected to working medium pressure, because liquid incompressibility between two oil sealings has stoped working medium by entering between axle and oil sealing shirt rim, the existence of viscous oil prevented that working medium from influencing bearing with permeation form.
The utility model is because only need to use 2 to have only shirt rim seal ring (" U " type oil sealing) and increase an oil-overflow cavity, and structure is simple especially, and because the existence of oil has improved seal ring shirt rim and axle friction, so the life-span is very long.Because its structural symmetry properties needn't be distinguished end or afterbody during assembling.
The concrete structure of model utility is provided by following examples and accompanying drawing.
Fig. 1 is according to the water pump seal device sectional drawing that the utility model proposes.
This device comprises an axle 1, on axle, put first shirt rim seal ring 3, in the seal ring outside is shell 2, the bearing of trend of direct-axis has cavity 5, be full of viscous oil (as common lubricating grease) therebetween, gas screw 4 is put in perforate on the cavity shell, and oil injecting screw 6, the cavity the other end are second shirt rim seal rings 7.
The shirt rim seal ring is annotated system by teflon, and the life-span is longer like this.
Claims (4)
1, the utility model is a kind of two-way immersion oil water seal, be used for rotary pump, particularly be the device in space between the sealing pivot of working medium pump and the pump housing with water, this device is made up of oil-overflow cavity 5 between seal ring 3,7 that has the shirt rim and seal ring, it is characterized in that:
A, described seal ring 3 and 7 are positioned at cavity 5 two ends, are housings 2 in its outside,
B, cavity 5 are full of oil.
2, according to the described device of claim 1., it is characterized in that: described seal ring 3 and 7 shirt rim are staggered relatively.
3, according to the described device of claim 1., it is characterized in that: described cavity 5 is placed bleed screw 4, oil injecting screw 6 by housing 2 perforates.
4, according to the described device of claim 1., it is characterized in that: the oil that is full of in the described cavity 5 is lubricating grease.
