The air compressor is not pressurized, and the compressor does not stop

The causes and solutions are as follows:

Check the dashboard to make sure that there are no errors or abnormalities in the settings of each data. After the pressure gauge data, at the same time to detect whether the display is correct, it may be out of control, the current real pressure value is not clearly expressed, many times why the air compressor can not be gasped is caused by this situation.

Air leakage can not be ignored, why the air compressor can not be gasped may also be pipes and other seals, damaged or not tight, resulting in the overall air output is insufficient, and the output of the model should be too large, which is not only a waste, but also the source of failure. Use professional tools to measure important parts and eliminate them one by one.

Air filter, its filter element is more susceptible to damage, especially when the air is bad, when the debris increases, it will lead to blockage, etc., should be cleaned regularly, and can be replaced in serious cases.

Check the compressor head and piston rings.

The exhaust pressure is too low (the gas volume is too low).

A: Check whether the manual valve and pressure gauge are leaking before and after separation, and replace the manual valve or eliminate the leakage fault if there is air leakage.

B: Check whether the regulating solenoid valve is leaking, if it is leaking, troubleshooting: replace the regulating solenoid valve if necessary.

C: Check the pipeline for leakage. If there is. Leaks need to be eliminated.

d: Check whether the butterfly valve is all open, if so, check the butterfly valve mechanism and solenoid valve: check whether the solenoid valve is leaking, if so, find out the reason and replace the solenoid valve.

e: Check whether the regulator is working normally, if there is a problem, you need to replace the solenoid valve or readjust the pressure switch, check whether the upper and lower limits of the pressure switch are normal, if so, you need to readjust the pressure switch, if necessary.

1. It may be that the barometer is out of order.

Observe the barometer, if the indicated pressure is insufficient, you can let the engine run at medium speed for a few minutes, the pressure still does not rise or rises slowly, when the brake pedal is pressed, the deflation sound is very strong, indicating that the barometer has been damaged, then the barometer should be repaired.

2. The transmission belt between the air compressor and the engine is too loose and slippery, or the pipeline between the air compressor and the air storage tank is broken or the joint is leaking.

Check whether the air compressor belt is too loose, from the air compressor to the air storage tank, to the control valve inlet pipe, and whether there is any air leakage.

3. The sediment of the oil-water separator, pipeline or air filter is too much and clogged.

The oil-water separator and air filter and the pipes should be checked for too much dirt that is causing clogging, and if it is blocked, the dirt should be removed.

Cleaning method. The long-term operation of the air compressor will lead to the equipment being clogged by scale, which will reduce efficiency, increase energy consumption and shorten the service life. If limescale is not removed in a timely manner, there is a danger that the equipment will be repaired, shut down or scrapped for replacement. For a long time, traditional cleaning methods such as mechanical methods (scraping, brushing), high-pressure water, chemical cleaning (pickling), etc., have many problems in the cleaning of air compressors

It cannot completely remove deposits such as scale, and causes corrosion to the equipment, and the residual acid produces secondary corrosion or underscale corrosion of the material, which eventually leads to the replacement of the equipment, in addition, the cleaning waste liquid is toxic, and a lot of money is required for wastewater treatment. Enterprises can use high-efficiency environmentally friendly cleaning agents to avoid the above situation, which has the characteristics of high efficiency, environmental protection, safety and no corrosion, not only good cleaning effect and no corrosion to the equipment, can ensure the long-term use of the air compressor.

The air compressor doesn't inhale, only exhale, and the pressure can't come up.

The main reasons why the air compressor does not inhale and only exhale are as follows: pretending to be Hu Yu 1 and the intake valve is not loaded. 2. Do not unload the inlet valve.

3. The solenoid valve is bad. 4. Poor air filter. Here's how to solve it:

1. If the inlet valve is not loaded, it may be that the module that controls the loading and unloading, that is, the regulating valve controls the closure of the inlet valve, resulting in no air intake. It is necessary to replace the module that controls loading and unloading. 2. If the inlet valve is not unloaded, it may be that the inner interception hole of the inlet valve is blocked.

It is necessary to clean the inner shut-off hole of the intake valve and other valve plates. 3. The solenoid valve may not be electrified, or the coil of the solenoid valve is damaged, and a new solenoid valve coil needs to be replaced. 4. The effect of the air filter is not good, and the sealing surface of the inlet valve core adheres to impurities resulting in poor sealing, and it is necessary to remove the impurities and replace a new air filter.

Other air compressor questions can be answered by private message I wish you a happy life :-)

Air compressors are used by manufacturers in various industries, and due to the difference in the quality of the equipment, they often fail during application. Common problems mainly include high-temperature shutdowns, frequent.

Busy loading and unloading causes the voltage to be too high to start. When an air compressor has a common failure, many customers are usually unclear about how to deal with it. The following is a summary of the snails.

A common fault that often occurs in rod air compressors.

One. The voltage is too high to start.

The screw air compressor is equipped with a voltage protection device. Under normal circumstances, the equipment will automatically start at low pressure, and it is normal for the equipment to stop automatically under high pressure. All.

The pressure-related pressure is automatically controlled by a pressure switch or pressure sensor. Therefore, usually the equipment has pressure problems, and generally only needs to adjust the pressure of the air compressor, adjust the operating range of the pressure power switch and the initial pressure set on the sensor. Look for the pressure adjustment option on the air compressor control panel to adjust.

Two. The voltage is too low.

1 Too low voltage is a problem that many customers are prone to, and the damage is generally higher. If the enterprise uses a power frequency air compressor, the power will be changed according to the adjustment of the transformer.

Press. If the main switching power supply voltage is 360V, the transformer must be replaced when 380V becomes 220V. However, the cost of dismantling and replacing the transformer with the motor is generally very high, so it is recommended to do so.

The manufacturer contacts in deciding on a workaround.

to change the output power, but the voltage cannot be higher than the input voltage. If the input voltage is 360V, the device with a rated voltage of 380V can only output 360V; False.

If the voltage is insufficient, the inverter will increase the current. As long as the current is not too large, it can be used normally. If the current is too high, you can also lower the upper limit frequency to ensure it.

Certify that the equipment is operating normally. It is inevitable that the screw machine air compressor will not work during the application process. Only by mastering the basic troubleshooting methods can the normal operation of the air compressor be guaranteed.

The piston machine has a switch that needs to be turned on. The screw machine needs to be turned on, if it can't be turned on, the back line of the controller is not discharged, if not, the controller is broken!

2) Check whether all pressure relay components of the air compressor power supply are damaged, and whether the given value of the pressure relay is appropriate.

3) Check whether there is any leakage of the working fluid in the temperature sensor package of the air compressor temperature controller, whether the components of the controller are damaged, and whether the temperature indication position is properly adjusted.

The air conditioner compressor is operating normally, but there is no pressure, what is the reason?

Dear, I am glad to answer for you: the air conditioning compressor is operating normally, but there is no pressure for the following reasons: if it is not running, it is likely to be caused by cold air prevention.

The reason for cold air prevention may either be the lack of refrigerant in the system, or the four-way reversing valve is not working, and the former is more likely. Situation 1: If the machine is turned on for a long time (generally more than 5min), and the low-pressure side continues to be "no pressure", it is very likely that the system is blocked; Scenario 2:

If the machine is turned on for a short time, there is "no pressure", and then the low pressure has a certain range of rapid liquid rise, and the refrigeration system is normal; (At this time, if the pressure is low, you can consider increasing the amount of refrigerant in the system appropriately) Supplement: It is very simple to determine whether the system is blocked, whether it is dirty or ice; The pressure relief and bypass device that may exist in the short-circuit system will be continuously turned on for 5 10 minutes, and then shut down, if the low-pressure pressure rises very slowly, it can be preliminarily concluded that the system is blocked; If the low-pressure pressure rises rapidly, it may be a crushing blockage, otherwise it is a "dirty blockage" or "welding blockage"; Suggestion: It is recommended that you directly replace the smashed globe valve and capillary, add lubricating oil, and refill the refrigerant; Do not force the machine to start many times, because in this case, the compressor is likely to be short of oil, not to mention the oil carbonization for a long time, and it is possible to burn out the compressor.

Summary. What is the reason why the air compressor cannot be pressed?

1. Increase in gas consumption

The power of the air compressor can not meet the requirements of the existing working environment, which will cause the air compressor to not pressurize, and this phenomenon needs to choose a replacement machine model.

2. There is a situation of gas consumption in the pipeline

Some pipelines may have small cracks due to time or maintenance, resulting in a decrease in gas pressure.

3. Air filter element blockage

The operating environment of the unit is poor, and the air filter is not cleaned or replaced in time, resulting in its blockage. Usually, the air filter will reduce the air production of the air compressor. Faults with blocked filters are also easy to find and deal with, as long as the filter element is replaced.

In fact, for air compressors, there are not many factors that cause pressure to go up, as long as you check them one by one, you can find the root cause.

4. The head is aging or malfunctioning

The machine head is the core of the air compressor, and it is an important part of the unit to suction and create pressure. If there is no problem in other positions, then the problem is usually here, after all, the process does not have problems, and there is a problem in the result, then the problem must be at the source, and the root cause of the problem that the air pressure of the air compressor cannot go up is the head.

5. Pressure switch problem:

This is also a must when the air compressor cannot be pressurized.

There is no reason why the pressure of the air compressor does not go up.

What is the reason why the air compressor cannot be pressurized 1. The increase in air consumption: the power of the air compressor cannot meet the requirements of the existing working environment will cause the air compressor to be unable to press, and this phenomenon needs to be replaced by the machine model. 2. There is a situation of gas consumption in the pipeline

Some pipelines may have small cracks due to time or maintenance, resulting in a decrease in gas pressure. 3. Blockage of the air filter: The operating environment of the unit is poor, and the air filter is not cleaned or replaced in time, resulting in its blockage.

Usually, the air filter will reduce the air production of the air compressor. Faults with blocked filters are also easy to find and deal with, as long as the filter element is replaced. In fact, for air compressors, there are not many factors that cause pressure to go up, as long as you check them one by one, you can find the root cause.

4. Aging or failure of the machine head: The machine head belongs to the core of the air compressor, and it is an important part of the unit to suction and create pressure. If there is no problem in other positions, then the problem is usually here, after all, the process does not have problems, and there is a problem in the result, then the problem must be at the source, and the root cause of the problem that the air pressure of the air compressor cannot go up is the head.

5. Pressure switch problem: This is also a must when the air compressor cannot be pressurized.

Why can't the main engine of the air compressor be pressurized?

The reasons why the air compressor host cannot press are as follows:

1) It is necessary to disassemble the host to confirm whether the leather bowl and cylinder inside the main engine are worn, and the leather bowl and cylinder should be replaced in time;

2) Check out the reasons for the leakage of the solenoid valve are:

When the air compressor is in continuous operation, and the body temperature is too high or the indoor temperature is too high, causing the solenoid valve coil to burn or the wire to be broken, the solenoid valve should be replaced in time, and indoor cooling measures should be taken;

When the solenoid valve is in a frequent start-stop state, the internal pilot head will be damaged, and the pilot head or solenoid valve should be replaced in time.
