When the lifting gun is refueled, the motor rotates slowly and heats up
1. Caused by motor damage, the internal coil of the three-phase motor is broken all the way and the starting capacitor of the single-phase motor is damaged, which will cause the load capacity of the motor to be reduced, and the motor rotates slowly and heats up when the fuel dispenser is turned on; 2. The damage to the circuit board that controls the motor will also cause difficulty in starting the motor, such as a three-phase thyristor board breaking all the way or the photosensitive thyristor conduction ability is low;
3. The problem of external distribution line will also cause the motor to rotate slowly and have heating phenomenon (such as three-phase power supply phase loss, distribution line is too far, wire diameter is too thin, voltage is too low, etc.).
In addition, we have other accessories such as Circular machine oiler, Control Panel, Adjustable Yarn Bobbin Cover, Synchronous Belt, Needle Cylinder and so on.
The exhaust pipe of the fuel dispenser spits out oil
1. The small float of the oil and gas separator cracks into the oil or falls off, the sealing performance of the valve seat of the outlet valve is not good, resulting in the failure of the outlet valve, a large amount of oil enters the atmospheric pressure cavity, the cone valve (oil return valve) does not return oil, and the oil can only be discharged from the exhaust pipe;
2. The large float cracks the oil inlet and the impurities at the lower end of the parallel valve are too much, resulting in the non-opening of the conical valve (oil return valve), and the oil in the atmospheric pressure chamber cannot return to the low-pressure cavity, resulting in the discharge of oil from the exhaust pipe;
3. The cover pad of the oil and gas separator is damaged, and a large amount of oil in the high-pressure cavity enters the atmospheric pressure cavity when refueling, resulting in oil spit out from the exhaust pipe;
4. The pump cover of the combined pump is damaged, the pump cover gasket is damaged, the oil and gas separation pipe is not tightly sealed, and the exhaust pipe will spit oil when refueling;
5. If you turn on the machine for many times without refueling, there will also be an oil spit phenomenon from the exhaust pipe, as long as you add oil, the oil spit phenomenon will disappear.
