The right lower quadrant of pump main body be provided with sewage draining exit, the lower wall of the inside of described pump main body is towards sewage draining exit direction into downward inclination
Shape, the bottom of described sewage draining exit is provided with blowoff valve.
Described cleaning case is split-type structural with pump main body.
The diameter with diameter greater than water inlet of described delivery port.
Described blowoff valve is connected by screw thread with sewage draining exit.
The beneficial effects of the utility model：Cleaning case is provided with by the upper right corner of the outside of pump main body, by cleaning case
Interior water purification is introduced directly into pump main body, and salting liquid and the salinity of precipitation that can be in time to being remained in pump main body be cleaned, pump
The salinity that the heavy caliber sewage draining exit of lower body part can be separated out with short-term storage, the lower wall of the inside of pump main body towards sewage draining exit direction into
Downward is skewed, is easy to the salinity for separating out to slide to sewage draining exit, when the salinity accumulated in sewage draining exit is excessive, can open blowdown
The salinity that valve will be separated out takes out, when needing to carry out great purge to sewage draining exit, blowoff valve can be taken off from sewage draining exit into
Row cleaning；Total the utility model have it is good to washed with saline solution effect, avoid salt residues in the pump housing, can effectively reduce plunger
The advantage of bar and ring wear.
