Embodiment Construction

[0014] The invention as Figure 1-2 As shown, it includes a water pump housing 1, a motor installed in the housing, a terminal block part and an impeller 2 installed on the top of the motor, and an agitating blade 3 is provided on the shaft of the motor near the suction port; The blade 3 is placed outside the impeller 2 and rotates coaxially with the impeller 2 . When impurities enter the position of the mixing blade 3 and the impeller 2 through the net cover 4, the impurities first contact the mixing blade 3, and under the joint action of the impact of the high-speed rotating mixing blade 3 and the vortex brought by the mixing blade 3, the impurities It is decomposed into fine particles, which can be smoothly discharged by the water pump.

[0015] The water pump motor is provided with a speed sensor, the water pump casing is also provided with a central processing unit, and the motor is also provided with an electromagnetic switch; the speed sensor and the electromagnetic sw...

Abstract

An anti-blocking water pump. It relates to a water pump. It can not only prevent rust blockage but also prevent impurities from entering and causing blockage problems. It includes a water pump housing, a motor installed in the housing, a wiring board part and an impeller installed on the upper part of the motor, and a stirring blade is arranged on the end of the shaft of the motor close to the water suction port; the stirring blade is placed on the impeller The outer side rotates coaxially with the impeller. The utility model has the advantages of simple structure and good anti-blocking effect.

Description

technical field [0001] The invention relates to a water pump, in particular to an anti-blocking water pump. Background technique [0002] At present, mechanically sealed water pumps are widely used in many fields such as fire protection, drainage, water boosting, agricultural irrigation, etc. Some are often used, and some are long-term standby. After a certain period of time, water leakage at the mechanical seal, rusty bearings, and If the rotor is blocked, it will not only cause water accumulation on the ground, but also may burn the motor if it is started accidentally. Although there are regular inspections and passive protection devices in many occasions, there are still many water pumps that cannot be started when they are urgently needed to start the water pump. This kind of report is also often seen in newspapers, especially serious is that the fire pumps have the above phenomenon. [0003] An invention patent published by the State Intellectual Property Office on Nov...
