Sewage pump selection (diving knife cutter) and precautions
Currently on the market all the sewage pumps are known as non-clogging sewage pump, then they are all in the true sense of the non-clogging it? Not necessarily! Often users of the sewage pump in the sewage pond in useless how long it was debris blocked the motor burned, so that many users are very headache, then no plug sewage pump is what kind of principle?
First of all, we analyze the sewage pump blocked several cases:
(1) sanitary napkins in septic tanks and other fibers;
(2) Convenient bags in hotels, guesthouses and kitchens;
(3) bath hair and convenience bags;
(4) puddles in the woven bags, braided rope, plastic bags.
It can be seen from the above situations that the plugging of the sewage pump is caused by some soft fibers. The general sewage pump can only discharge some muddy water mixture with sediment or granule, so only the sewage pump that can crush the soft fiber can be called non-clogged sewage pump.
At present, the general structure of the sewage pump on the market is S-type flow channel flat impeller and closed flow type impeller, and the pollutant discharge effect is relatively good. In the selection still pay attention to the following points:
(1) the diameter of the sewage pump as far as possible choose DN65 or DN80 above.
(2) The best choice of impeller strength of the material.
However, the real non-clogging submersible sewage pump is a submersible reamer pump, provided by Shanghai Jiu Pump Co., Ltd. MPE series of submerged cutter water pump completely solve the problem of clogging the sewage pump, it has a group of carbide knife, all through the runner Was shattered. Now many property companies have been blocked by the sewage pump burned motor problems plagued by the use of submerged cutter knife, the original problems solved, only the submersible cutter knife can solve the bathroom renovation and the best choice for sewage discharge.
