Description

[Correction 20.06.2016 by Rule 26] 자동 Automatic cleaning device for filtration filter of motor pump

The present invention relates to an automatic filtration filter cleaning device for a motor pump for cleaning filtration elements of a motor pump for pumping water, and more particularly, for a filtration element for filtering a foreign substance contained in a fluid drawn into the motor pump. The present invention relates to an automatic filtration filter cleaning device for a motor pump that can automatically clean the branched driving force to increase pumping efficiency and convenience of maintenance.

In general, a submersible motor pump is a device installed in the water to force the fluid such as sewage or drainage flows, such a motor pump is directly connected to the electric motor providing a driving force to one side of the pump performing the pumping action and integrated The pump has a structure such as a centrifugal pump, a multi-stage turbine pump, an axial flow pump, a sewage pump, a bladeless pump, and the like, and since the rotating part is in the water, there is no noise and vibration, and the structure is simple. Easily handled, it is widely used for water, sewage, water supply and drainage, and home wells.

In addition, the electric motor has a structure such as a water repellent type, a watertight type, etc., for internal water, and the water pump of the pump does not need to be lubricated because the water is lubricated. That is, the submersible motor pump is manufactured to be resistant to corrosion and good airtight due to the characteristics installed in the water, and the motor is installed on one side in the longitudinal direction to provide a rotational force as a general rotational force, and work water while rotating by the rotational force of the motor. It consists of an impeller which is a pumping element pumping in the direction, and a suction flow path for sucking water is formed between the motor and the impeller. In addition, a pipe or the like for supplying water to a nozzle or the like of a fountain device is connected to an impeller side end of the submersible motor pump.

Here, the water motor pump is sucked with a strong suction force for high lift, when the water flows through the suction flow can be introduced into the foreign substances such as sand, fallen leaves and vinyl, and in the wastewater treatment facility various solids and sludge Etc. may be introduced. If the foreign matter enters through the suction channel, the foreign matter may be caught in the impeller and the operation of the submersible pump may be stopped, or the water discharged from the discharge port of the submersible pump may become turbid so that the entire interior of the tank may be turbid. In order to solve this problem, a strainer, which is a filtering element, is installed on the suction channel side to prevent foreign substances from entering the suction channel, and thus only water from which the foreign substances have been removed can be introduced through the suction channel.

Was to be separated.

However, when the protective filter or strainer is installed on the suction channel side of the motor pump, foreign substances flowing into the pump can be reduced to maintain the pump's operating efficiency stably and reduce the occurrence of trouble caused by foreign substances. When the foreign matter is adsorbed or adhered to the outer surface of the protective filter or strainer, the pumping efficiency decreases as the water flow rate decreases rapidly, and there is a problem of causing the fixing of the motor pump when the state is left for a long time. In order to solve this problem, the filter or strainer should be replaced or cleaned periodically. To this end, since the pump must be dismantled and assembled while the pump is stopped, the operation efficiency of the pump is not reduced and it depends on manual operation.
