What is the reason for the frequent tripping of the single screw air compressor

The trip is mainly when the unit starts, at that time the load driven by the motor is very large, and there are only a few places that generally lead to the problem, 1, the voltage of the line connecting the air compressor is not stable or the voltage is not enough. For example, there are other devices connected to this lying line.

2. When the unit starts, the inlet valve is originally closed, but it is not closed, resulting in the air entering the main engine in advance and increasing the load at start-up.

3. The failure of the motor or the host itself, such as the damage of the bearing, can be manually rotated to try.

4. According to the landlord's question in this period, it can be considered that in winter, the decrease in ambient temperature will lead to the increase in the viscosity of the lubricating oil inside the unit, and the tripping phenomenon will occur when the unit is cold.

Possible reasons for the self-tripping of the screw air compressor: the exhaust temperature is high, the air compressor trips by itself, and the exhaust high temperature indicator light is on (more than the set value of 100) may be the cause.

1. The amount of lubricating oil is insufficient.

Insufficient cooling water.

3. High temperature of cooling water.

4. High ambient temperature.

5. Oil cooler betting.

6. The specification of lubricating oil is incorrect.

7. Thermal control valve failure.

8. The air filter is not clean.

The air compressor oil filter is blocked.

10. The cooling fan is faulty.

11. The air duct of the air-cooled cooler is blocked.

12. The oil flow is too small.

13. The temperature switch is faulty.

The screw air compressor trips by itself.

2. Check the temperature difference between the inlet and outlet water pipes.

3. Check the temperature of the inlet water.

4. Increase exhaust air and reduce room temperature.

Check the temperature difference of the inlet and outlet water pipes, the normal temperature difference is 5, if it is greater than 9, the oil cooler may be blocked, remove it and clean it with chemicals.

6. Check the oil number and replace the oil.

Check that the oil has been cooled by the oil compressor cooler, and replace the thermal control valve if not.

8. Clean the air filter with low-pressure air.

Replace the oil filter.

10. Replace the cooling fan.

11. Low-pressure air cleaning cooler.

12. Adjust the oil flow control valve.

Replacement. To sum up, there are many reasons for the tripping of the screw air compressor, so you must not panic when you encounter the tripping problem, check it according to the above methods first, and if you really can't solve the problem, you can consult the air compressor maintenance master.

This is the air compressor protection tripping, there are two situations: one is the air compressor without electric control, this trip indicates that it is overloaded, the reason may be that the air compressor exhaust is blocked, not passing, the other is with electric control, tripping is related to multiple factors, the air compressor has multiple temperature detection points, and pressure detection points, these pressures, abnormal temperature will lead to tripping.

1. Check whether there is a problem with the leakage protection switch, if the protection switch has a small number of amplifications or the switch contact is ablated, the starting motor will trip.

2. Check the wire for leakage.

3. Check whether the motor has leakage.

The voltage of this line connected to the air compressor is unstable or the voltage is insufficient.

It should be a small empty opening, the starting current is very large, and frequent start-up will trip frequently!

The customer's total air opening trips frequently, and the electrician summarizes three reasons, air opening aging, overload, and poor contact.

Hello, dear, what is the cause of the air compressor trip problem? 1.Because the starting current of the air compressor is relatively large, the setting current of the power switch is relatively small, and the starting current of the motor is not avoided; 2.

The motor has faulty grounding or phase-to-phase fault short circuit; 3.If the temperature of the air compressor is too high, it will also cause tripping; 4.The main engine does not run smoothly (caused by poor environment and poor maintenance or bearing problems); 5.

Check the lubricating oil level of the air compressor. Air compressor is the basic product of industrial modernization, and it is often said that electrical and automation has the meaning of full pneumatic; The air compressor is to provide air source power, is the core equipment of the pneumatic system electromechanical air source device in the main body, it is the original mover (usually the motor) of the mechanical energy into gas pressure energy of the device, is the compressed air pressure generation device.

What is the cause of the air compressor trip problem?

Tripping on the way to work.

What is the cause of the air compressor trip problem? Hello dear, there may be reasons as follows:1

Because the starting current of the air compressor is relatively large, the setting current of the power switch is relatively small, and the starting current of the motor is not avoided; 2.The motor has faulty grounding or phase-to-phase fault short circuit; 3.If the temperature of the air compressor is too high, it will also cause tripping; 4.

Oil-free. Hello dear, please follow the above description.

1. It is necessary to determine whether the trip refers to the overload protector bounced or the air switch in the power supply circuit bounced.

2. If it is an empty opening, first determine how big the specifications of this empty opening are, judge whether it can bear the load of the machine, and whether the conversion is overloaded as follows: 20A air opening, the machine power is 6KW, 6000W 220V = 27A, the selected air opening is small, and you need to change to a large air switch.

3. If the specifications of the empty opening are sufficient, it may be a short circuit in the machine, and it is necessary to check the circuit of the machine to determine whether there is a short circuit.

4. It may be that the machine leakage, at present, some air openings on the market are equipped with leakage protection switches, such as the insulation layer of the live parts on the machine is damaged, it will lead to the leakage current becoming larger, once the leakage current to the ground is greater than 30mA air opening will jump open. If this is the case, it is necessary to use professional equipment to check which electrical components are resistant to voltage, or replace them one by one to check and confirm.

1. Because the starting current of the air compressor is relatively large, the setting current of the power switch is relatively small, and the starting current of the motor is not avoided;

2. The motor has faulty grounding or phase-to-phase fault short circuit.

First of all, check the pressure gauge of the air compressor oil and gas barrel, if it shows pressure, it is preliminarily judged that there is pressure in the air compressor system, which causes the air compressor to start under pressure, causing the starting current to be too high, and the air switch trips to protect the unit. This is usually caused by a malfunction of the minimum pressure valve, or a blockage in the pressure relief system.

Or you can, the role of lubricating oil in the screw compressor is very important, its role is mainly manifested in four aspects: cooling, lubrication, sealing, noise reduction, and the quality of the oil, the amount of oil directly affects the normal operation of the air compressor and the service life of the air compressor, especially the most obvious impact on the head part of the air compressor.

Get some lube on it.

It is also possible that the temperature is too high, or there is oil coking in the head.

I thought it was a problem with the oil, and it didn't work even if I saved the oil.

The starting time of the motor on the air switch is slightly extended under the condition of ensuring safety, so as to meet the extension of the starting time of the compressor when the oil viscosity increases, so as to ensure the normal start of the air compressor.

It seems that the current is relatively large is a short circuit or contactor failure, a boot should be the air compressor control system to measure the current is relatively large without protection, only after the conversion of the current can be protected,

It should be that the motor is short-circuited or the live wire is grounded.

What does it mean that the switch of the motor tripped.

1. Because the starting current of the air compressor is relatively large, the setting current of the power switch is relatively small, and the starting current of the motor is not avoided;

Solution: Adjust the startup current.

2. The motor has faulty grounding or phase-to-phase fault short circuit.

Solution: Repair the motor.

Hello dear, 1The voltage is too low, but it is not detected with a voltmeter. 2.

Whether the transformer capacity is large enough, due to the use of air conditioners and electrical appliances in summer, may lead to insufficient transformer capacity 3If the temperature of the air compressor is too high, it will also cause tripping4Check the current of the main engine, generally the air compressor will have the main motor protection function.

5.The main engine is not running smoothly (caused by poor environmental maintenance or bearing collapse problems) 6Check the lubricating oil level of the air compressor.
