Recently, the air compressor starts frequently, and it is automatically started once every 1~2 minutes, and each operation is about 10s. This is more than ten minutes between the starting time and the normal working time. The difference of each operation is about 15s. Checking the gas situation, it is found that there is no big difference between the gas volume and the gas pressure, and there is no obvious leakage in the gas supply pipeline; whether the gas storage tank of the air compressor has accumulated water, and the water storage volume is not found to be small; The motor is basically normal except for the heat generated by the starter is too frequent, and the mechanical part of the air compressor has no obvious part failure. The problem is concentrated on the pneumatic automatic switch of the air compressor electrical system.
The structural principle of the GYD20 pneumatic automatic switch, the opening and closing of the fixed contact 8 and the movable contact 9 determine the working state of the air compressor. The moving contact is fixed on the top of the bakelite block. When the bakelite block is driven by the springboard venting valve, it jumps to the lower end point, and the movable contact is disengaged from the fixed contact, and the motor on the air compressor is powered off. The right end of the springboard can be rotated about the left end of the rotating shaft, one end of the spring is fixed on the springboard, and the other end is fixed on the pressure plate. When the springboard quickly jumps clockwise, the bakelite block is driven to disconnect the main contact, and the motor is de-energized to stop running. At this time, the air pressure of the air tank is at the highest value set.
The pressure of the gas storage tank passes through the air inlet to lift the piston column. As long as the height of the pressure plate 2 exceeds the equilibrium point above the springboard rotation axis, the springboard quickly jumps clockwise to the lower right and remains stable under the action of the spring. When the air pressure is insufficient, the main spring 3 presses the pressure plate, and as long as it is lower than the balance point below the springboard rotation axis, the springboard quickly jumps counterclockwise to the position shown. Rotating the screw moves the nut up and down to adjust the pressure of the main spring to determine how close and close the contact is under the pressure of the air reservoir.
