The sewage pump was not long used in the sewage pool and was blocked by debris, causing the motor to burn out, causing many users to be very puzzled. So what is the principle of a non clogged sewage pump?
Common debris caused by blocked sewage pumps:
1. Convenience bags in hotels, guesthouses, and kitchens;
2. Hair and convenience bags in the shower center;
3. Woven bags, woven ropes, and plastic bags in puddles;
4. Fibers such as sanitary pads in septic tanks;
From the above situations, it can be seen that the blockage of the sewage pump is caused by some soft fibers. A typical sewage pump can only discharge a mixture of mud and water containing sediment or particles, so only sewage pumps that can crush the aforementioned soft fibers can be called non clogging sewage pumps. At present, the general structure of sewage pumps on the market is an S-shaped flow channel flat impeller and a closed flow channel impeller, which have good sewage discharge effects.
The following points should still be noted in the selection of sewage pumps:
1. The diameter of the sewage pump should be selected as DN65 or DN80 or above as much as possible.
2. The impeller should be made of materials with higher strength.
3. The AS submersible sewage pump bottom solves the problem of sewage pump blockage, and all AS pumps are equipped with adjusted tearing mechanisms that can tear apart long fibers, bags, belts, grass, cloth strips, etc. in the sewage and discharge them. Therefore, working in sewage without clogging is extremely reliable. Nowadays, many property management companies have been troubled by the problem of sewage pumps being blocked and burning out motors. After adopting the AS type submersible sewage pump, the original problem has been easily solved. The AS type submersible sewage pump can solve the problems of toilet renovation and clubhouse sewage discharge blockage.
The key issue for sewage pumps is reliability, as the medium to be transported is a mixture of liquid containing solid materials. This problem makes the requirements for sealing, motor bearing capacity, bearing arrangement, and selection of sewage pumps higher than general pumps. Therefore, when selecting a type, it is important to understand the sealing reliability and bearing capacity of sewage pumps.
In order to improve the service life of sewage pumps, most manufacturers both domestically and internationally have come up with solutions for pump protection systems, which can automatically alarm and shut down for repair in case of pump leakage, overload, overtemperature, and other faults.
However, we believe that it is necessary to install a protection system in the sewage pump, as it can effectively protect the safe operation of the electric pump. But this is not the key to the problem, the protection system is just a remedy after a pump failure, and it is a relatively passive approach.
The key to the problem should be to start from the root and thoroughly solve the problems of pump sealing, overload, etc. This is a more proactive approach. For this reason, we have applied the hydrodynamic sealing technology of the auxiliary impeller and the non overload design technology of the pump to the submersible sewage pump, greatly improving the sealing reliability and bearing capacity of the pump, and extending the service life of the pump.
Sewage pumps can transport media containing hard solids, as well as particularly dirty, sticky, and slippery media. Therefore, sewage pumps are widely used in various fields such as mining, papermaking, petroleum, chemical, food, fertilizer, mud, and sewage ponds. Sewage pumps are different from submersible pumps, where the motor and pump are integrated and directly put into the sewage to work, while sewage pumps are installed directly on the ground to work. There are many models of sewage pumps, let's analyze the sewage pump models below.
The QW submersible sewage pump, like the submersible pump, is a potential source of sewage. QW means non clogging, and ordinary carbon steel materials are generally not resistant to some acidic and alkaline substances in sewage. They are prone to corrosion, while stainless steel can be corrosion-resistant.
JYWQ is equipped with an automatic mixing and suction system for sewage, which is less prone to blockage.
The WL type sewage pump is installed vertically. YW is a submerged sewage pump with the characteristics of a submerged pump, and the same applies to AS. However, AS generally requires the use of rubber hoses.
ZW type self priming sewage pump achieves self priming function. It is designed to exhaust air and absorb medium containing air through idle operation, and the medium fills the pump body to complete self priming．
