The utility model is further arranged to: the fastening part is equipped with counterbore, and cover board is equipped with the spiral shell being connected to counterbore
Pit is bolted between counterbore and threaded hole, and spring washer is arranged on bolt.
The utility model is further arranged to: being additionally provided with annular groove on the cover board, is equipped in annular groove for close with fastening part
The rubber ring of envelope.
The utility model is further arranged to: being additionally provided with reinforcement part on the connecting pin of the pump cover and cover board.
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；Bolt is hidden in the design structure in deep hole, prevents overcurrent Mediawear bolt from causing connection loosing and difficult in maintenance.
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, quick coupling；7,
Cover board；8, positioning region；9, fastening part；10, counterbore；11, bolt；12, rubber ring；13, reinforcement part.
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 chamber, including pump cover 1 and the machine capping 2 for being placed in 1 side of pump cover, pump cover 1 and machine
Mechanical seal 3 is equipped between capping 2, it is characterised in that: the chamber 4 for filling cooling medium, pump cover are equipped in the pump cover 1
It is additionally provided with two liquid injection holes being connected to respectively with 4 upper and lower ends of chamber on 1 side wall, is connected between two liquid injection holes by sebific duct 5,
Sebific duct 5 is transparent.
Cooling effect is played to mechanical seal 3 for filling cooling medium in chamber 4, it is different by two high and low positions
Liquid injection hole setting can be replaced in the case where not disassembling electric pump, fill cooling medium, and be observed in chamber 4 by transparent hose 5
Whether whether the service condition of cooling medium reduce convenient for observation cooling medium, need to fill again, and may determine that mechanical close
Whether envelope 3 has failed.
The quick coupling 6 for being threadedly coupled with liquid injection hole is equipped on 5 both ends of sebific duct, glue is convenient in quick coupling 6
The fast quick-detach of pipe 5 and liquid injection hole, it is more convenient and practical.
