Description

High efficiency and long life submersible pump

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a mouth-and-mouth pump for moving water in the water to the ground, and more particularly, to a drain pump that tilts at an angle of 45 ° to reduce resistance due to water discharge, , And a vibration damping means is formed between the motor and the concrete installed on the ground, thereby reducing the failure rate of the pump and increasing the life of the pump.

Generally, it is a device for discharging the fluid stored in the water tank to the outside, which is located in the water of the nozzle pump water tank. The conventional chopper pump includes a casing formed with a suction port and a discharge port, an impeller disposed at a lower portion of the casing for sucking and discharging the fluid, and a drive motor coupled to the impeller and having a drive shaft for rotating the impeller, And a bearing for smoothly rotating the drive shaft is installed in the support portion.

Such a chilling pump sucks and discharges fluid by rotating the driving shaft of the driving motor while the suction port is submerged in the water. In the case where a chilling pump is installed in a water collecting tank including a foreign substance, There has been a problem that foreign matter is caught by the impeller and the efficiency of the pump is lowered.

In addition, since the conventional inlet / outlet pump is formed such that the discharge port is inclined by 90 degrees, the flow direction of the fluid is suddenly changed to slow the flow rate, and the fluid discharge amount is reduced, and vibration and noise are additionally generated. As a result, not only the resistance of the impeller is generated but also the life of the motor is shortened due to the overload of the motor, the residual current is generated, and the power consumption is increased.

In addition, the motor bed, the pump bed, and the discharge port for fixing the motor are exposed to the ground, thereby deteriorating the aesthetics, and increasing maintenance and initial pump manufacture and installation costs.

Therefore, it is necessary to develop a poppet pump which can increase the discharge amount of the fluid, prolong the service life of the motor, reduce the power consumption, reduce vibration and noise, and reduce the maintenance and installation cost.
