Abstract
The utility model belongs to the technical field of pump appliances and particularly relates to a front abrasion-resistant lining plate for an underwater pump. The front abrasion-resistant lining plate for the underwater pump comprises a disk body and is characterized in that a through hole is arranged at the position in the middle of the disk body and is gradually shrunk from bottom to top, two annular grooves are arranged on the disk body with the through hole serving as the center, and a plurality of fixing holes are arranged at the positions in the middle of the two annular grooves. The front abrasion-resistant lining plate for the underwater pump is simple in structure and convenient to use, the underwater pump can be protected extremely well, and service life of the underwater pump is prolonged.
Description
Technical field
The utility model belongs to pump apparatus technical field, relates in particular to the preceding abrasion-proof backing block of a kind of submersible pump.
Background technique
Submersible pump generally all carries out river dredging under water and uses.So in the process of using, usually can be because the cause of dredging has things such as some mud, sandstone to be inhaled into the inside.By suction some foreign matters of bottom, river are cleaned out.But, because some is that edge is sharper or granularity is bigger in these foreign matters under water.So when suction was big, the front end of the submersible pump that is easy to wear and tear caused damage.
Summary of the invention
The purpose of this utility model is to solve above-described technical problem, provides a kind of submersible pump preceding abrasion-proof backing block, and its technological scheme is as follows:
Abrasion-proof backing block before a kind of submersible pump comprises disk body, it is characterized in that, the place offers through hole in the middle of the described disk body, described through hole shrinks from the bottom to top gradually, offers two annular grooves on the described disk body centered by through hole, and the place is provided with some fixed holes in the middle of described two annular grooves.
Optimal way is, the upper end diameter of described through hole is 800-850mm, and the lower end diameter of described through hole is 900-950mm.
Abrasion-proof backing block before the submersible pump that the utility model provides when in use, can be placed on preceding abrasion-proof backing block the front end of submersible pump, fixes by fixed hole then.And the middle place of disk body offers through hole, and described through hole shrinks from the bottom to top gradually.The foreign matter that make to suck can not result in blockage in the time of can be fast by through hole.Centered by through hole, offer two annular grooves on the described disk body, can be so that other parts tabling of preceding abrasion-proof backing block and submersible pump by annular groove, make between the two fixing more stable.
The upper end diameter of through hole described in the utility model is 800-850mm, and the lower end diameter of described through hole is 900-950mm.By continuous experiment and actual the use, under above-mentioned clear size of opening, it is best that the effect of aspirated foreign body water conservancy diversion can reach.
The utility model is simple in structure, and is easy to use, can be good at protecting submersible pump, makes obtain prolonging the service time of submersible pump.
