Description

Durable water pump for sewage treatment

Technical Field

The utility model relates to a water pump technical field, especially a durable type water pump for sewage treatment.

Background

Sewage treatment is a process of purifying sewage to meet the water quality requirement of discharging the sewage into a certain water body or reusing the sewage. Sewage treatment is widely applied to various fields such as buildings, agriculture, traffic, energy, petrifaction, environmental protection, urban landscape, medical treatment, catering and the like, and is increasingly used in daily life of common people. The sewage treatment station is used for treating production and domestic sewage, reaches the specified discharge standard and is an important facility for protecting the environment. The industrial developed countries have common sewage treatment stations, but the villages and the towns in China have few sewage treatment stations, but the stations are gradually increased in the future. In order to make these sewage treatment stations really function, it is necessary to ensure the sewage treatment stations by strict discharge system, organization and management system. The sewage pump belongs to one of centrifugal impurity pumps, and has various forms: such as a submersible type and a dry type, the most common submersible type is a QW type submersible sewage pump, and the most common dry type is a W type horizontal sewage pump and a WL type vertical sewage pump. The device is mainly used for conveying urban sewage, excrement or liquid containing fibers. The temperature of the medium, which is a solid particle such as paper dust, is usually not higher than 80 ℃. The conveyed medium contains fiber matter easy to twine or bunch. Therefore, the flow passage of the pump is easy to block, once the pump is blocked, the pump cannot work normally, and even the motor is burnt, so that the sewage discharge is not smooth. Bringing serious influence to city life and environmental protection. Therefore, the anti-blocking performance and reliability are important factors of the quality of the sewage pump, however, the sewage pump is only named as an application, and in fact, the application of the rubber-lined slurry pump as a horizontal sewage pump is good. When industrial sewage is treated, the rubber-lined pumps are widely used because the sewage contains acidic or alkaline substances. According to some application cases of pump industry, the rubber sheath and the metal impeller are used in the rubber-lined pump, so that the high pressure and high efficiency of the metal pump can be achieved, and the corrosion resistance of the rubber material can be fully exerted. When urban sewage is treated, a filter screen is added in front of a sewage treatment tank generally, and fiber winding and the like are blocked in front of a suction inlet of a pump, so that the fiber winding and the like cannot enter a pump cavity, the pump can work better, and the service life is longer.

The prior durable water pump for sewage treatment has the following defects:

1. solid waste in the sewage is more, the pump body is easy to block during sewage treatment, and the anti-blocking effect of the existing pump body is poor;

2. the anti-blocking of the existing equipment is mainly completed by a filter screen, but the filter screen is easy to block to influence the water pumping efficiency.
