Description
Technical field
The utility model is related to canned motor pump auxiliary device, more particularly to a kind of canned motor pump fills safely pump exhaust apparatus.
Background technology
Canned motor pump is a kind of stationary seal pump, and pump and driving motor are all sealed in the pressure that a pumped medium is full of
In container, this pressure vessel only has static seal, and is provided rotating excitation field by an electric wire group and driven rotor.This structure takes
The sealing device for rotary shaft that the conventional centrifugal pump that disappeared has, therefore can accomplish complete No leakage.Canned motor pump is lubricated using pumped (conveying) medium
Sliding bearing, by pumping or the material medium of pump outer circulation to sliding bearing lubricating and cools down, but some pumped (conveying) mediums
Low boiling point, easily vaporization or pump will not pump in vivo gas before pump is opened and be completely exhausted out, during pump operation, to sliding axle
The medium for holding lubrication cooling is just replaced by gas phase media, greatly reduces lubrication, the effect of cooling, bearing temperature is caused to raise,
Serious wear or even bearing breakage cause the damage of pump.
In polysilicon industry, the conveying of chlorosilane material uses canned motor pump substantially, comes into operation after new pump comes into operation, overhauls
When, it is required for gas phase in pump being completely exhausted out, once gas phase will cause pump bearing to damage without all discharging.Some screens at present
It is to fill pump exhaust manually from pump tail to cover pump, but fills pump valve using small-sized needle valve, and filling pump valve is arranged to air,
Very big danger and the destruction to environment are caused after noxious material discharge, and needle valve is used for multiple times rear sealing performance and declines,
Chlorosilane medium is caused to leak outside, the medium leaked out is more serious to valve, pump housing corrosion, and there are safety collars for poisonous medium leakage
Hidden danger is protected, this mode has been not suitable with production requirement and safety and environmental protection requirement at this stage.
The content of the invention
It fills pump exhaust apparatus safely the technical problem to be solved by the utility model is to provide a kind of canned motor pump, realizes and fill pump
Medium does not leak outside in exhaust process, and dielectric film filter is utilized, and both reduces material waste, also reduces safety and environmental protection risk.
In order to solve the above technical problems, technical solution is used by the utility model：A kind of canned motor pump fills safely pump row
Device of air, including canned motor pump, the canned motor pump tail end connects regulating valve, and the regulating valve connects discharge duct, the exhaust pipe
Road connects tracheae and materail tube by threeway, and tracheae one end leads to purge gas, and tracheae is equipped with ball valve, and materail tube passes through fast quick access
Head is connected with medium discharge duct line.
In preferred scheme, the discharge duct includes first pipe and second pipe, one end of first pipe and adjusting
Valve connects, and the other end is connected by articulation with second pipe, and second pipe connects tracheae and materail tube, the first pipe by threeway
After road and articulation disconnect, one end installation silk plug of the first pipe away from regulating valve.
In preferred scheme, the materail tube is transparent hose.
In preferred scheme, the tracheae is equipped with pressure gauge.
In preferred scheme, the purge gas that described tracheae one end leads to is nitrogen.
A kind of canned motor pump provided by the utility model fills safely pump exhaust apparatus, is conveyed medium by the materail tube of setting
To medium discharge duct line, medium is delivered to by designated position by medium discharge duct line, avoids medium in filling pump exhaust process
Leakage, while also dielectric film filter is utilized, has both reduced medium waste, also reduced safety and environmental protection risk；The tracheae of setting,
By leading to purge gas the medium in each pipeline is made to purge totally, ensure dismounting safety.The silk plug of setting, avoids in canned motor pump
Medium leaked outside by regulating valve.Whether the transparent hose of setting flows out convenient for observation medium.The pressure gauge of setting passes through pressure
Power table can determine that the pressure of purge gas is more than the pressure in priming device pipeline, and poisonous medium is avoided to move back to purge gas
In system.
Description of the drawings
The utility model is described in further detail with reference to the accompanying drawings and examples：
Fig. 1 is the overall structure diagram of the utility model.
In figure：Canned motor pump 1, regulating valve 2, discharge duct 3, tracheae 4, materail tube 5, ball valve 6, quick coupling 7, articulation 8,
Silk plug 9, pressure gauge 10, first pipe 301, second pipe 302.
Specific embodiment
In Fig. 1, a kind of canned motor pump fills safely pump exhaust apparatus, and including canned motor pump 1,1 tail end of canned motor pump passes through pipe
Road is welded to connect regulating valve 2, and the regulating valve 2 connects discharge duct 3, and the discharge duct 3 connects tracheae 4 and object by threeway
Expects pipe 5,4 one end of tracheae lead to purge gas, and tracheae 4 is equipped with ball valve 6, and materail tube 5 passes through quick coupling 7 and medium discharge duct line
Connection.The purge gas that described 4 one end of tracheae leads to is nitrogen.Tracheae 4 can pass through quick coupling and purge gas system pipeline
Connection, is easy for installation and removal.
Expects pipe 5 is connected by quick coupling 7 with medium discharge duct line, and medium is delivered to reception dress by medium discharge duct line
It puts, it is ensured that the pressure in reception device is less than the pressure filled in pump exhaust apparatus, to ensure that medium can be successfully from canned motor pump
Interior discharge.
The discharge duct 3 includes first pipe 301 and second pipe 302, one end and the regulating valve 2 of first pipe 301
Connection, the other end are connected by articulation 8 with second pipe 302, and second pipe 302 connects tracheae 4 and materail tube by threeway
