Description
Technical field
The utility model belongs to electric pump technical field, refers in particular to a kind of pump environment-friendly type self-circulating machine sealing chamber.
Background technique
It is usually realized and is sealed by mechanical seal between the pump housing and motor of existing electric pump, but armature spindle meeting and mechanical seal
It rubs and generates amount of heat, it is therefore desirable to which cooling medium is cooling, but there is problems, intracavitary cooling Jie of conventional seals
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.
Utility model content
The purpose of the utility model is to provide a kind of achievable cooling cycle and convenient for the pump environment-friendly type self-loopa of observation
Mechanical seal chamber.
Purpose of the utility model is realized as follows: a kind of pump environment-friendly type self-circulating machine sealing chamber, including pump cover
It is covered with the machine for being placed in pump cover side, is equipped 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 sebific duct is transparent.
The utility model is further arranged to: is equipped on the end of the sebific duct for connecting with inlet opening or fluid hole
Quick coupling.
The utility model is further arranged to: the pump cover includes being placed in pump cover side and the cover board with machine capping connection,
Machine capping includes the fastening part that is placed in the indoor positioning region of chamber, connect with cover board, fastening part and positioning region integrally connected, cover board and
It is bolted between fastening part, and is additionally provided with sealing ring between cover board and fastening part.
The utility model is further arranged to: the cooling medium is water.
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；When cooling requirement recycles in the higher medium of electric pump delivery temperature, chamber, chamber can be intracorporal cold with the case of external connection
But liquid forms 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, quickly
Connector；9, cover board；10, positioning region；11, fastening part；12, bolt；13, sealing 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 self-circulating machine sealing chamber covers 2 including pump cover 1 and the machine for being placed in 1 side of pump cover, pump cover
Mechanical seal 3 is equipped between 1 and 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 sebific duct 5 is transparent.
By the setting of two high and low position difference liquid injection holes, it can be replaced in the case where not disassembling electric pump, fill cooling
Liquid, and medium situation in chamber 4 is directly observed by transparent hose 5, so that 3 operating status of mechanical seal is judged, when electric pump is defeated
When sending temperature is higher to cross flow medium, lower part cooling medium first heats up in chamber 4, and lower part cooling medium can be certainly since temperature raises
Row is flowed upwardly into cabinet 6, and the lower cooling medium of temperature can sink to flowing into chamber 4 in cabinet 6, therefore by cooling
The temperature difference of medium itself forms self-loopa, has better cooling effect.
The quick coupling 8 for connecting with inlet opening or fluid hole, quick coupling 8 are equipped on the end of the sebific duct 5
It is more convenient and practical convenient for the fast quick-detach of sebific duct 5 and inlet opening or fluid hole.
The pump cover 1 includes the cover board 9 for being placed in 1 side of pump cover and connecting with machine capping 2, and machine capping 2 includes being placed in chamber 4
Interior positioning region 10, the fastening part 11 being connect with cover board 9, fastening part 11 and 10 integrally connected of positioning region, cover board 9 and fastening part 11
Between it is fixed by bolt 12, and sealing ring 13 is additionally provided between cover board 9 and fastening part 11.
The cooling medium is water, and cooling medium selects the cleaning of water or similar water, environmentally friendly medium, prevents from being situated between to overcurrent
Matter pollutes.
Above-described embodiment is only the preferred embodiment of the utility model, not limits the protection model of the utility model according to this
It encloses, therefore: the equivalence changes that all structures, shape, principle according to the utility model are done should all be covered by the protection of the utility model
Within the scope of.
