Matter is not easy to replace, and if in seal chamber cooling medium leak, it is also not noticeable；When conveying high temperature crosses flow medium, cooling medium pole
Easily heating, cooling effect substantially reduce；Fastener on seal chamber is located in the pump housing, is easy to impact and grind by flow medium
Damage, corrosion, service life substantially reduce.
Utility model content
The purpose of the utility model is to provide the recyclable pump environment-friendly type mechanical seals cooling and with long service life of one kind
Cavity configuration.
Purpose of the utility model is realized as follows: it is a kind of pump use environment-friendly type mechanical seal cavity configuration, including pump cover and
It is placed in the machine capping of pump cover side, is additionally provided with mechanical seal between pump cover and machine capping, it is characterised in that: be equipped in the pump cover
For filling the chamber of cooling medium, the inlet opening being connected to respectively with chamber upper and lower ends and out liquid are additionally provided on pump cover side wall
It is respectively connected with sebific duct on hole, inlet opening and fluid hole, two sebific ducts are commonly connected on a cabinet, and pump cover includes being placed in pump cover
Side and the cover board connected with machine capping, cover board are equipped with threaded hole, and machine capping is equipped with the counterbore being connected to threaded hole, counterbore
The interior bolt being equipped with for being connected to threaded hole, and spring washer is arranged on bolt.
The utility model is further arranged to: the end of the sebific duct is equipped with for connecting with inlet opening or fluid hole
Quick coupling.
The utility model is further arranged to: the cover board is equipped with annular groove, be equipped in annular groove for machine lidstock
Rubber ring.
The utility model is further arranged to: the sebific duct is transparent.
The utility model is further arranged to: the cooling medium is water.
The utility model is further arranged to: the material that the pump cover and machine cover is stainless steel material.
Electric pump can not disassembled by the setting of two high and low position difference liquid injection holes by using above-mentioned technical proposal
In the case where replacement, filling coolant liquid, and medium situation in chamber is directly observed by transparent hose, to judge mechanical seal
Operating status；Cooling and lubricating medium selects the similar cleaning with water, environmentally friendly medium in seal chamber, prevents from causing dirt to flow medium excessively
Dye；Bolt is hidden in the design structure in deep hole, prevents overcurrent Mediawear bolt from causing connection loosing and difficult in maintenance；Work as electricity
The higher medium of delivery temperature is pumped, in chamber when cooling requirement circulation, chamber can be with the intracorporal coolant liquid shape of case of external connection
At self-loopa.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Appended drawing reference in figure are as follows: 1, pump cover；2, machine covers；3, mechanical seal；4, chamber；5, sebific duct；6, cabinet；8, it covers
Plate；9, counterbore；10, bolt；11, quick coupling；12, rubber ring.
Specific embodiment
The utility model is further described with specific embodiment with reference to the accompanying drawing, referring to Fig. 1:
A kind of pump environment-friendly type mechanical seal cavity configuration covers 2 including pump cover 1 and the machine for being placed in 1 side of pump cover, pump cover 1
Mechanical seal 3 is additionally provided between machine capping 2, it is characterised in that: the chamber for filling cooling medium is equipped in the pump cover 1
4, it is additionally provided with the inlet opening and fluid hole being connected to respectively with 4 upper and lower ends of chamber on 1 side wall of pump cover, on inlet opening and fluid hole
It is connected with sebific duct 5, two sebific ducts 5 are commonly connected on a cabinet 6, and pump cover 1 includes being placed in 1 side of pump cover and covering 2 with machine
The cover board 8 of connection, cover board 8 are equipped with threaded hole, and machine capping 2 is equipped with the counterbore 9 being connected to threaded hole, is equipped with and uses in counterbore 9
Spring washer is arranged in the bolt 10 being connected to threaded hole, and on bolt 10.
By the setting of inlet opening and fluid hole, it can be replaced in the case where not disassembling electric pump, fill coolant liquid, cabinet 6
It is interior that for storing cooling medium, when electric pump delivery temperature is higher crosses flow medium, lower part cooling medium first heats up in chamber 4,
Lower part cooling medium can voluntarily be flowed upwardly into cabinet 6 since temperature raises, in cabinet 6 the lower cooling medium of temperature can under
It is heavy to flow into chamber 4, therefore self-loopa is formed by the temperature difference of cooling medium itself, improve the cooling to mechanical seal 3
Interior six point cylindrical head bolt 10 can be selected in speed, bolt 10, is designed by the structure of counterbore 9, the socket cap of bolt 10 can be hidden
In in counterbore 9, preventing overcurrent Mediawear bolt 10, its connection loosing and difficult in maintenance is caused, by the setting of spring washer,
The possibility that bolt 10 loosens can be reduced by the elasticity of spring washer.
The end of the sebific duct 5 is equipped with the quick coupling 11 for connecting with inlet opening or fluid hole, quick coupling 11
It is more convenient and practical convenient for the fast quick-detach of sebific duct 5 and inlet opening or fluid hole.
