Abstract
The utility model provides a kind of exhaust apparatus for vertical pipeline mounted pump, including：Hollow connecting rod, vent valve, fixed block, bolt, it is characterized in that：Described hollow connecting rod one end is fixedly connected with vent valve, other end edge from electric machine support lower flange disk is through to machine sealing chamber, and it is tightly connected with machine sealing chamber, in electric machine support lower flange disk outer rim curved surface, fixed block is set, the fixed block is bolted to connection with electric machine support, and the fixed block is fixedly connected with hollow connecting rod.During exhaust, vent valve is opened, the air in machine sealing chamber is extruded by intracavitary water, is discharged by connecting rod, after exhaust, closes vent valve；The utility model can discharge whirlpool gas in riser pump housing, the cavitation that cavity and blade is greatly reduced, the service life for extending vertical pipeline mounted pump, the service behaviour for improving vertical pipeline mounted pump.
Description
Technical field
It the utility model is related to a kind of exhaust apparatus of water pump.
Background technology
The operation principle of traditional vertical pipeline pump is：Rotated, the water that water inlet enters is accelerated, due to centrifugation by blade
The effect of power, water turn to delivery port along the inwall of pump case, simultaneously because the sealed environment of pump case, can by water from water inlet not
Disconnected suction；Exhaust process before riser pump work, exactly in order to create the sealed environment of pump case, traditional exhaust process
It is：The terminal valve of pump to be opened, makes to be full of water in pump, while turns on outlet pipe plug with spanner and is vented, pipe plug to be exported sprays water,
Outlet pipe plug is screwed on spanner, exhaust is completed；At present, the switch of conventional outlet pipe plug will use spanner, it is impossible to which operation is arrived in time
Position, causing spray splash everywhere after the completion of exhaust, influence the working environment of pump house, the exhaust apparatus of improvement also has a lot, but by
In the machine sealing chamber horizontal level of some vertical pipeline mounted pumps higher than importing and exporting, it is incomplete that these exhaust apparatus can not still solve exhaust
Phenomenon, cause cavity and blade serious cavitation occur, influence the physical life and service behaviour of pump.
Utility model content
The defects of in order to overcome the exhaust mode of existing vertical pipeline mounted pump to exist, the utility model provide a kind of operation side
Just, simple and practical, safe and reliable, the exhaust apparatus for vertical pipeline mounted pump.
What the technical solution of the utility model was realized in：
A kind of exhaust apparatus for vertical pipeline mounted pump, including：Hollow connecting rod, vent valve, fixed block, bolt, it is special
Sign is：Described hollow connecting rod one end is fixedly connected with vent valve, and other end edge from electric machine support lower flange disk is through to
Pump mechanical seal water chamber, and be tightly connected with machine sealing chamber, in electric machine support lower flange disk outer rim curved surface, fixed block, the fixation are set
Block is bolted to connection with electric machine support, and the fixed block is bolted to connection with hollow connecting rod, described hollow
Connecting rod connects one end of vent valve, connection flexible pipe.
It is fixedly connected with electric machine support below the motor of vertical pipeline mounted pump, is fixedly connected below electric machine support with pump case, electricity
Arbor one end connects motor, and one end passes through electric machine support, and blade stretched into pump case chamber, during exhaust, opens the terminal valve of pump, makes
It is hydraulically full in pump, while the vent valve in connecting rod is opened, liquid constantly enters cavity, and gas is close by machine sealing chamber top
The hollow connecting rod of envelope connection extrudes, until flexible pipe has liquid discharge, completes exhaust, and then realize discharge riser pump housing
Whirlpool gas, the cavitation that cavity and blade is greatly reduced, the service life for extending vertical pipeline mounted pump, improve vertical pipeline mounted pump
Service behaviour.
Relative to prior art, the utility model has the advantage that：
1st, the utility model is improved the horizontal level of steam vent, discharged by the hollow connecting rod being connected on machine sealing chamber
Whirlpool gas in cavity, the cavitation of cavity and blade is greatly reduced, service behaviour, the extension for improving vertical pipeline mounted pump are vertical
The physical life of pipeline pump.
2nd, the utility model realizes the simple control to exhaust work by the vent valve being connected in hollow connecting rod.
3rd, the utility model is led by being connected to the flexible pipe of hollow connecting rod outer end to the water discharged in exhaust process
Stream, avoids in conventional exhaust mode that The water splash in all directions, ensure that the working environment of pump chamber is clean and tidy.
Brief description of the drawings
Fig. 1 is profile of the utility model on vertical pipeline mounted pump；
Fig. 2 is profile of the utility model on vertical pipeline mounted pump；
Fig. 3 is sectional perspective explosive view of the utility model on vertical pipeline mounted pump.
Embodiment
Below with reference to the accompanying drawings and implementation is combined to describe the utility model in detail.
A kind of exhaust apparatus for vertical pipeline mounted pump, including：Hollow connecting rod 1, vent valve 2, fixed block 3, bolt 4,
It is characterized in that：Described one end of hollow connecting rod 1 is fixedly connected with vent valve 3, and the other end is from edge on the lower flange disk of electric machine support 5
Machine sealing chamber 7 is through to, and is tightly connected with machine sealing chamber 7, fixed block 2, institute are set in the lower flange disk outer rim curved surface of electric machine support 5
State fixed block 2 to be fixedly connected by bolt 4 with electric machine support 5, the fixed block 3 is fixed with hollow connecting rod 1 by bolt 4 to be connected
Connect, the hollow connecting rod 1 connects one end of vent valve 2, connection flexible pipe 11.
Operation principle of the present utility model is：The lower section of motor 8 of vertical pipeline mounted pump is fixedly connected with electric machine support 5, motor
The lower section of support 5 is fixedly connected with pump case 6, and the one end of motor shaft 9 connection motor 8, one end passes through electric machine support 5, will consolidated with motor shaft 9
Surely the blade connected stretches into pump case chamber 10, during exhaust, opens the terminal valve of pump, makes hydraulically full in pump, while opens connection
Vent valve 2 on bar 1, liquid constantly enter cavity, and the hollow connecting rod 1 that gas is connected by the end sealing of machine sealing chamber 7 is pressed
Go out, until flexible pipe 11 has liquid discharge, complete exhaust, and then realize the whirlpool gas of discharge riser pump housing, chamber is greatly reduced
The cavitation of body and blade, the service life for extending vertical pipeline mounted pump, the service behaviour for improving vertical pipeline mounted pump.
