Blood Pressure Air Pump Motor suppliers Circuit failure is mainly caused by unstable voltage, lack of phase, unbalanced voltage, large circuit resistance, and poor contact of contactor contacts. The resulting failures are mainly manifested as: 1. The air pump has low wind power. 2. The wind of the air pump is sometimes large and sometimes small. 3. The motor is easily damaged or cannot be started. 4. The motor is noisy and vibrates. The reasons and troubleshooting methods are: 1. The low wind power of the air pump is mainly due to the decrease of the motor speed caused by the large power consumption, the oxidation of the joint or the poor insulation of the motor, thereby reducing the wind power of the air pump. The troubleshooting method is: the line should have a certain load and not be overloaded, and the wire should be checked for heat generation. If the heat is more serious, use thicker wires or wires with a high energization rate under permitted conditions, or reduce the circuit load. If the resistance of the thread is large, the oxidation head should be cut off and re-wired. If the wire itself has insulating paint, it should be thoroughly cleaned and then the thread should be connected tightly. If the motor is damp, you can use a light bulb or oven to dry it and use it after reaching normal requirements. 2. The wind of the air pump is sometimes large and sometimes small. Mainly due to unstable voltage, insufficient joints or serious oxidation of the wire leads to the unstable operation of the motor and the uneven wind force. The troubleshooting method is: if the power supply voltage is unstable, check whether the power consumption is stable. If this occurs, the line should be changed or other corresponding measures should be taken, and the work should be stopped if the treatment is not appropriate. If the power switch is in poor contact or the transformer is faulty, it should be repaired in time, and work should be performed after reaching normal.
