Blood pressure air pump horse motor, air pump common failure is mainly caused by the following aspects: 1, natural wear natural wear is mainly due to a longer service period, some vulnerable parts of the original function can not play its role normally, the use of performance gradually decreased.The main faults caused by this are as follows :1. The wind force of the air pump gradually decreases.2. The air pump is leaking oil.3. The air pump is noisy.4. Air pump rotation is not flexible.There is a card or frequent card phenomenon, and accompanied by strong friction issued by the "哜哜" sound, at the same time the motor temperature rise significantly higher.5. In the case of no debris collision of the cooling air page, the cooling air page is easy to damage.1. The reason why the wind force of the air pump gradually decreases is that :① the steel blade on the air pump rotor is seriously worn.Its formation process is: because the air pump in the work of the rotor for high-speed movement, so that the steel blade on it under the action of centrifugal force close to the outer wall for circular movement.Because the outer wall of the blade through the suction, blowing hole and the rotor at both ends of the slip ring, the air pump in normal operation at both ends of the blade is not subject to friction (that is, the slip ring part), suction, blowing hole by a certain amount of impact, the blade gradually lose edges and corners.Because the blade has wear parts and non-wear parts, and wear conditions are different, so the blade from the original straight surface gradually into a curved surface, when the blade is removed, with the hand to touch the working surface there is a feeling of hanging hand, more serious can be observed on the gap.
