Abstract

The invention discloses a liquid pump, which comprises a case, a stator component, a rotor component and a pump cover. The case comprises a motor casing and a sealing separator with an upper opening, wherein the opening of the sealing separator is tightly sealed by a sealing cover to form a middle first containing chamber, the sealing separator is mounted in the motor casing to form a second containing chamber enclosing the first containing chamber, the stator component is mounted in the second containing chamber, the rotor component is rotatably inserted on the first containing chamber, the sealing cover is provided with an annular groove, and an annular stopper synchronously rotating with an impeller is correspondingly arranged in the groove in a matched manner and extends into the annular groove. Further, a sealing spacer is arranged at the position of a mandrel between the impeller and the sealing cover. By the aid of the scheme, multiple separation effects for metal chips in water flow can be achieved, so that the metal chips can be prevented from entering a rotor and blocking the rotor.

Description

technical field

[0001] The invention relates to the technology in the field of pumping equipment, in particular to a liquid pump with convenient assembly and good stability. Background technique

[0002] When machining metal parts with mechanical processing equipment (such as lathes, milling machines, drilling machines, planers, etc.), it is necessary to use coolant (cooling water) to cool the processing position, and at the same time wash away many metal fines that are processed. Next, the waste water with metal fines will be concentrated into a liquid storage pool or tank, and then the waste water will be pumped away and filtered by a liquid pump for recycling. Because this waste water contains a lot of metal shavings or other fine shavings, when using a common pump for suction, these metal shavings will be attracted by the magnet rotor in the motor and stick to the rotor, which will easily block the rotor and prevent the rotor from rotating. Therefore need to use a kind ...
