Abstract

The invention discloses an axial force automatic balancing device, a water pump and an air conditioner. The axial force automatic balancing device comprises a pump body, an impeller arranged in the pump body and a pump cover arranged on the pump body; the impeller comprises a rear cover plate and a rear opening ring arranged on the rear cover plate, an annular groove in clearance fit with the rearopening ring is formed in the pump cover, and a balance cavity is formed among the rear cover plate of the impeller, the pump cover and the rear opening ring; and a balance hole communicating with the balance cavity is formed in the rear cover plate of the impeller, an annular boss is arranged on the inner surface of the pump cover, and part of the balance hole is covered with the annular boss. According to the axial force automatic balancing device, the impeller can reach a balance point during motion through the structure, so that automatic balancing of axial force is achieved, the influence of axial force on the reliability of the water pump can be reduced, and normal opening of the water pump is ensured.

Description

technical field [0001] The invention relates to the technical field of air conditioning, and more specifically relates to an axial force automatic balancing device, a water pump and an air conditioner. Background technique [0002] During the operation of the water pump, an axial force acts on the rotor along the axial direction of the rotor, and this force will pull the rotor to move along its axial direction. When the axial force is too large, the bearing of the rotor will be damaged quickly, causing the impeller to collide with the pump casing, vibration and friction occur, and the axial clearance becomes larger, which affects the reliability of the water pump and causes the water pump to fail to operate normally. Contents of the invention [0003] In order to solve the problem in the prior art that the reliability of the water pump is affected by excessive axial force and the pump cannot operate normally, the present invention provides an automatic balance device for a...
