Description
Technical field
This utility model is related to pump housing resist technology field, specifically be a kind of pump housing protection device.
Background technology
Due to the different pump housing type differences used using scene, the stronger liquid of some corrosivity needs special material
The pump housing made by material.At present, as the pump housing made by special material is expensive, for small business's heavy load, typically all
Using the pump housing made by common material, as the pump housing cannot be excluded using the liquid in rear pipeline and the pump housing, in the pump housing, meeting Jing is normal
A certain amount of liquid is remained, pump housing seriously corroded is made, causes pump housing service life to shorten.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of pump housing protection dress for extending pump housing service life
Put.
For solving the above problems, pump housing protection device described in the utility model, including the pump housing, motor and shaft coupling, institute
State motor and the pump housing is connected by the shaft coupling, the pump housing import is provided with feed pipe, and its outlet is provided with discharge nozzle；It is described enter
Expects pipe is provided with low level discharging tube；The discharge nozzle is provided with high-order discharging tube；The low level discharging tube and the high-order discharge opeing
Valve is respectively equipped with pipe；The low level discharging tube and the high-order discharge opeing pipe end are provided with residual liquid tank.
Further, the low level discharging tube and the high-order discharging tube are respectively provided at the feed pipe and the discharge nozzle
Extreme lower position.
Further, the low level discharging tube and the high-order discharging tube are obliquely installed.
This utility model has advantages below compared with prior art：
This utility model, can be respectively due to being respectively equipped with low level discharging tube and high-order discharging tube on feed pipe and discharge nozzle
Discharge remains in the corrosive liquids in the pump housing and pipeline, shortens the corrosion rate of the pump housing, extends the service life of the pump housing.
Description of the drawings
Fig. 1 is this utility model structural representation.
In figure：1st, discharge nozzle, 2, the pump housing, 3, motor, 4, shaft coupling, 5, feed pipe, 6, valve, 7, low level discharging tube, 8,
Residual liquid tank, 9, high-order discharging tube.
Specific embodiment
Pump housing protection device described in the utility model, including the pump housing 2, motor 3 and shaft coupling 4, motor 3 passes through axle device 4
The connection pump housing 2,2 import of the pump housing are provided with feed pipe 5, and its outlet is provided with discharge nozzle 1；Feed pipe 5 and the punishment of 1 extreme lower position of discharge nozzle
Low level discharging tube 7 and high-order discharging tube 9 are not provided with；Valve 6 is respectively equipped with low level discharging tube 7 and high-order discharging tube 9；Low level is arranged
Liquid pipe 7 and high-order discharging tube 9 are obliquely installed and end connection residual liquid tank 8.
Utility model works process is as follows：The valve 6 closed on low level discharging tube 7 and high-order discharging tube 9, starts motor
3 power supply, motor 3 drive the pump housing 2 to work by shaft coupling 4, and liquid is transported to discharge nozzle 1 from feed pipe 5 by the pump housing 2,
After 2 end-of-job of the pump housing, the valve on low level discharging tube 7 and high-order discharging tube 9 is opened respectively, by pipeline and in the pump housing 2
Residual liquid drain in residual liquid tank 8, in the pump housing 2 will not Jing often remain corrosive liquids, extend the service life of the pump housing 2.
