Abstract

The invention discloses a non-clogging sewage pump. The non-clogging sewage pump comprises a pump body, a motor and an impeller, wherein a water suction opening and a water draining opening are formed in the pump body. The non-clogging sewage pump further comprises a sealing seat and an oil chamber, wherein the sealing seat is arranged between the pump body and the motor, the oil chamber is arranged on the sealing seat in a sleeving manner in the circumferential direction, an annular oil storage chamber is formed between the oil chamber and the sealing seat, a containing hole for the rotary shaft of the motor to penetrate through is formed in the middle of the sealing seat, the lower bearing of the motor is installed above the containing hole, and a mechanical seal is arranged below the lower bearing and between the rotary shaft and the containing hole. According to the non-clogging sewage pump, the impeller is driven by the motor to rotate at a high speed so that eddy currents can be generated to achieve medium conveying, and furthermore, because of the open type impeller and an ample pass way designed in a volute casing, various solid particles, even fiber sundries prone to intertwining, in mediums all can be sent out without obstruction as long as the particles or sundries can enter the water suction opening of the volute casing, and the effect of no clogging is really achieved.

Description

technical field [0001] The sewage pump related to the invention particularly relates to a non-clogging sewage pump.
