Submersible sewage pump with the anti clogging performance is why more and more attention?
This is mainly due to two reasons:
First, the increase in the cost of sewage disposal. Industrial enterprises are trying to reduce the amount of water consumed in the production of a unit of production, which makes the content of solid matter and fiber in waste water more and more high.
Two: sewage pump is more and more use of the means of energy saving, is the speed regulation of the drive, and speed regulation can not guarantee that the sewage pump will not be blocked.
Aiming at the frequent plugging machine impurity pump impeller, the initial operation of the equipment used by each block will clear, not overnight cleaning method. Although this avoids the work stoppage, but often remove the pump body, causing the machine pump mouth ring and other parts of the wear and tear at the same time every time consuming a lot of manpower. In order to change this situation, the water inlet pipe of the machine is equipped with carbon steel resistance box, and a 45 dip angle. The filter screen is used to filter the impurities in order to avoid clogging. The team to carry out the pollution for 1 to 3 times per month. After the implementation of this program has received a certain effect, the human consumption has been alleviated. At the bottom of the dirt blocking box has a vent valve, but there are still dead. Part of the sewage and impurities in the accumulation of dead ends, in the clean up of personnel caused by minor gas poisoning damage, is not conducive to safe operation.
The shape of the rotor blade of submersible sewage pump is divided into two types, which are swirl vane and cutting blade, the most widely used of these two forms. Swirl impeller is not in the medium to be transported in the movement, according to the principle of fluid dynamics, the need to pump the medium into the pump chamber, the medium is pumped from the impeller flow. In this way, the liquid medium is pumped by a long fiber or solid material is also pumped out together. And cutting blades, the larger solid material can be chopped, and thus no longer blocked.
