The air compressor is 37 kilowatts, and the motor is overloaded and shut down when loaded to 5 kg

Air compressor overload shutdown:

First, there are many problems that lead to overload of air compressor motors

1. The ambient temperature is high.

2. The motor coil temperature is high.

3. Poor pressure setting.

4. There is a problem with the power supply of the factory.

5. Unstable gas consumption.

6. Oil distraction and blockage.

7. The pressure controller fails.

8. Air leakage from the joint of the pressure controller.

9. The venting valve cannot be opened.

10. The unloading valve is not closed.

11. The air compressor oil is wrong.

12. Host failure.

13. The current is too high.

Second, the fault phenomenon:

1. The pressure of the unit is low. The actual gas consumption is greater than the output gas volume of the unit; The air release valve is faulty and cannot be closed when loading; Failure of the intake valve; Failure of hydraulic cylinders; Load solenoid valve failure; The minimum pressure valve is stuck; There is a leak in the user's pipe network; The pressure setting is too low; Pressure sensors; Failure of the pressure gauge; The pressure switch is faulty, and the pressure sensor or gauge input hose is leaking.

2. The exhaust temperature of the unit is more than 100 degrees. The coolant level of the unit is too low, which should be visible from the oil speculum, but not more than half; The oil cooler is dirty; The oil filter core is clogged; Failure of the thermostat valve (broken element); The oil shut-off solenoid valve is not energized or the coil is damaged; Fracture or aging of the diaphragm of the oil cut-off solenoid valve; Fan motor failure; Damage to the cooling fan; The exhaust duct is not smooth or the exhaust resistance (back pressure) is large; The ambient temperature exceeds the specified range (38 or 46); The temperature sensor is faulty.

3. The fuel consumption of the unit is large or the oil content of the compressed air is large. The cooling dose is too much, and the correct position should be observed when the unit is loaded, and the oil level should not be higher than half at this time; clogged return line; The installation of the return pipe (the distance from the bottom of the oil separator core) does not meet the requirements; The exhaust pressure is too low when the unit is running; rupture of the oil separator core; The internal partition of the separating cylinder is damaged; There is oil leakage in the unit; Coolant deterioration or overdue use.

4. The exhaust pressure of the unit is too high. Failure of the intake valve; Failure of hydraulic cylinders; Load solenoid valve failure; The pressure setting is too high; Faulty pressure sensor; Failure of the pressure gauge; The pressure switch is faulty.

5. The current of the unit is large. The voltage is too low; Loose wiring; The pressure of the unit exceeds the rated pressure; The exhaust pressure is too low when the unit is running; Oil separator core blockage; Contactor failure; host failure; The main motor is faulty.

6. The fan motor is overloaded. fan deformation; Fan motor failure; Fan motor thermal relay failure (aging); Loose wiring; Cooler blockage; High exhaust resistance.

The air compressor is 37 kilowatts, and the motor is overloaded and shut down when it is loaded to 5 kg: first check what is the current of the motor overload shutdown, and then reset the start and use the clamp meter to actually detect the input current. Compare it to see if it is caused by the problem with the controller or if the motor is actually overcurrent and overloaded;

A: There is a problem with the controller system:

1: Caused by the failure of the current transformer.

2: The controller is faulty.

B: The actual overcurrent overload shutdown of the motor: there are two problems that need to be checked:

1 Motor problems: motor continues to fail or electrical failure.

2. The main engine is faulty, resulting in overload operation of the motor, overcurrent and overload shutdown.

If you have any questions, find the manufacturer for after-sales.

Electrical and mechanical failures.

1. The voltage is too low, the contactor is faulty, the phase is missing, and the overload is caused.

2. Overload caused by the failure of the compression host.

Solution. 1. In order to ensure the input voltage frequency, Yunchun should add a voltage regulator, which can ensure that the input voltage frequency does not belong to the corresponding voltage range of the air compressor.

2. Sometimes the check valve can not play a one-way role, and there is still a phenomenon of gas backflow in the gas tank, if you want to solve the problem at this time, you need to clean the iron filings on the surface of the valve core in the check valve in time.

3. When we check that the solenoid valve cannot be unloaded or the unloading time is too long, then the solenoid valve should be replaced in time, which is the only solution.

4. If there is an overload phenomenon when the main engine is running, it is necessary to disassemble the main engine and check whether the valve plate inside the main engine is deformed. If deformation is confirmed, the valve disc or manifold should be replaced.

5. If there is an overload phenomenon immediately after the main engine is powered on, at this time, it is necessary to disassemble the metal hose and the fan cover of the main engine to manually rotate the fan blades. Generally, if the fan blade does not move, there is a problem with the main engine bearing, which can replace the main engine.

6. The air compressor of some manufacturers has too high fuselage temperature and high indoor temperature, which is usually caused by the air compressor being in a state of continuous operation for a long time. The easiest way to solve the problem is to take cooling measures in time, and the easiest way is to increase the fan to dissipate heat from the air compressor.

7. If the internal spring of the boat-type switch or overload protector corresponding to the host falls off, the spring should be re-fixed with the pressure switch. <>

Summary. There may be several reasons for the overload shutdown of the air compressor host:1

Air pressure is too high: When the air pressure exceeds the rated pressure of the main engine of the air compressor, the main machine will automatically shut down to avoid damaging the equipment. 2.

Overheating protection: When the main engine of the air compressor runs for too long or the ambient temperature is too high, the main machine will automatically shut down to avoid overheating damage. 3.

Power failure: When the power supply voltage is unstable or the power line is faulty, the air compressor host may be overloaded and shut down. 4.

Overload protection: When the main load of the air compressor is too large or the load increases suddenly, the main machine will automatically stop to avoid overload damage. 5.

Mechanical failure: When the main engine of the air compressor has mechanical failure, such as bearing damage, gear wear, etc., the main engine may be overloaded and shut down.

I'm sorry I don't understand, but can you elaborate on that?

Summary. Hello, the answer to your question: one of the reasons why the air compressor current is too high may be that the connection part of the air compressor is stuck, and the equipment cannot be transmitted or operated; The second reason may be that the pump head is stuck; The third reason may be that the vacuum oil is too viscous and the equipment cannot be operated.

50 kilowatt generator with 22 kilowatt air compressor, air compressor shows what is going on with excessive current.

Hello, the answer to your question: one of the reasons why the air compressor current is too high may be that the connection part of the air compressor is stuck, and the equipment cannot be transmitted or operated; The second reason may be that the pump head is stuck; The third reason for the original book of the front servant may be that the vacuum oil is too viscous and noisy, and the equipment cannot be operated.

The power supply is out of phase and the voltage is abnormal, the voltage is abnormal and the lack of cracks can easily destroy any motor, and the power cord of the motor must be able to carry the rated current of the motor, which causes the current of the air compressor motor to be too high.
