Tianshui Jufeng's LGCY-23 27 fixed screw air compressor adopts the design idea of "large rotor, large bearing, low speed", and the speed is 30 50% lower than that of other brands, which can reduce noise and vibration, reduce exhaust temperature, improve rotor rigidity, prolong service life, and reduce susceptibility to impurities and oil carbide. The output of the compressor is connected to the gas tank, and there is a preliminary condensation in the gas tank, so it is often necessary to open the drain valve at the bottom of the gas tank frequently to drain water, or install a timed automatic drain valve to drain water regularly. A refrigerated refrigeration dryer is installed when the air tank comes out, so that the compressed air from the air tank quickly cools and removes most of the water molecules in the compressed air.

What does it mean to be undercharged? My understanding is that the air compressor of 8 kg is less than 8 kg of air pressure from the pressure gauge. 1.

First close all the air compressor outlet valves, see if the air compressor can hit 8 kg, if it can reach 8 kg, there will be no problem with the air compressor, that is, your air consumption is too much. If you can't get it, it means that there is a problem with your air compressor and needs to be repaired.

Hello dear, how to solve the problem that the air pressure of the air compressor is not enough? How to maintain it? 1. If the air pressure of the air compressor is not enough, you can adjust the air pressure, there is a screw in the switch that can be adjusted up or low, the normal compressor factory setting is 8 pressures, if you feel that the air pressure is not enough, you can adjust it to 9 kg or 10 kg.

2. Under normal circumstances, 8 kg for all pneumatic tools is enough, individual instruments and equipment may need to be adjusted to 9 kg, or your pipeline is too long to affect its pressure, you can make some corresponding adjustments. 3. If it is screw air compressor maintenance, it is generally 3000 hours or 5000 hours, if there is an electrician or their own understanding of machine maintenance, you can maintain it yourself, or call a professional person to come to maintain, the maintenance is relatively simple, change some air filters, oil filters to change the oil. 4. If it is a connecting rod air compressor, the maintenance cycle is generally 3 to 5 months, change the oil, replace the air filter, and discharge the water from the air tank regularly, I hope it can help you.

If my answer is helpful to you, please give a thumbs up (in the lower left corner), I look forward to your like, your efforts are very important to me, and your support is also the motivation for my progress. Finally, I wish you good health and a good mood!

Cause.

1. The intake filter is faulty.

When the intake filter is clogged with accumulated dirt, the exhaust volume is reduced; If the length of the suction tube is too long, or the diameter of the tube is too small, it will also increase the inspiratory resistance and affect the exhaust volume.

Cause. Second, the speed of the compressor is reduced.

The exhaust volume of the compressor is generally designed according to the suction temperature and humidity and altitude, when the discharging volume is set below the standard requirements of the altitude, the suction pressure will be reduced, and the exhaust volume will be reduced accordingly.

Cause. 3. Wear and tear of parts and increase of clearance.

The cylinder, piston ring, and piston are seriously worn, and the increase in the distance between them will increase the leakage, which will affect the exhaust volume. If it is a regular wear and tear, the device can be replaced in time; If it is caused by incorrect installation, it can be corrected according to the drawing.

Cause. Fourth, the stuffing letter is not strict.

This will cause air leakage and reduce the air volume, the first reason may be that there is a problem in the design and production of the stuffing box itself, and the second reason may be that there is a problem in the piston rod and stuffing box during installation, which is easy to produce strain and wear, and then air leakage. The solution can be to add lubricating oil to the stuffing box to lubricate or seal.

Cause. 5. Failure of exhaust valve and compressor.

Debris such as metal fragments may fall between the valve plate and the seat of the valve, which can cause air leakage. The reason for this problem is the quality of the valve plate, and the second is the air leakage due to the wear of the valve seat and valve plate.

Cause. Sixth, the spring force of the gas valve is not well matched with the gas force.

Excessive elasticity will cause the valve to open slowly, which will affect the exhaust volume; If it is too weak, it will affect the air volume due to the valve plate not closing in time.

Cause. 7. Improper compression of the air valve.

Too little compression force will cause air leakage, and too tight will cause distortion and damage to the valve cover.

Therefore, when the exhaust volume of the air compressor is abnormal, we must investigate it one by one, and solve the problem after clarification.

Insufficient air pressure Failure Cause:

1. The barometer malfunctioned.

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.

3. The oil-water separator, pipeline or air filter is clogged due to excessive sediment.

4. The air compressor exhaust valve is not tightly sealed, the spring is too soft or broken, the cylinder head bolts of the air compressor are loose, and the sand hole and cylinder head gasket are damaged and leak.

5. The cylinder liner of the air compressor is worn out with the piston and piston ring and even leaks.

It may be a malfunction, it is recommended to find a professional to check it.

1. The air compressor pressure release valve is stuck. The valve disc is deformed or broken.

2. Excessive carbon accumulation at the inlet and exhaust ports of the air compressor. Judgment and elimination method of air compressor failure: 1. Check the pressure loosening valve assembly, clean and replace the failed parts. 2. Disassemble and inspect the cylinder head, check the valve plate, and replace the deformed and broken valve plate.

3. Disassemble and inspect the cylinder head, clean the valve seat plate and valve plate.

There is a leak in the air. Park your car in a quiet place with full gas and listen to the ** leaking. If you can't hear it, try to see if there's any wind blowing out from under the dryer's muffler.

Automatically ran out of gas in four hours? There is a leak in the air. Park your car in a quiet place with full gas and listen to the ** leaking. If you can't hear it, try to see if there's any wind blowing out from under the dryer's muffler.

The main reasons for the insufficient air supply of the air compressor are as follows:

1. The air filter is blocked, and the air intake is reduced.

2. Where there is air leakage at the air end, check the pipeline.

3. If the gas equipment becomes more and cannot be satisfied, it is necessary to add an air compressor.

4. The filter behind the air compressor is blocked, and the pressure difference is large and affects the pressure of the air end.

5. The loading and unloading solenoid valve is broken, and the air compressor is not loaded.

When the air compressor is running, the outlet pressure will be too low, which cannot meet the production demand, resulting in the following factors that the outlet pressure of the air compressor is too low

1. The on-site gas consumption of the air compressor is too large. Generally, it is recommended that customers check the pipeline for air leakage;

2. The failure of the air intake valve of the air compressor leads to insufficient valve opening. Remove the intake valve for maintenance, or replace the repair kit;

3. The air intake valve of the air compressor controls the air source leakage, resulting in insufficient valve opening or unable to open. The air leakage part needs to be removed;

4. The pressure switch of the air compressor sets the working pressure too low. The upper pressure limit should be raised upward;

5. The pressure switch of the air compressor is faulty, resulting in the working pressure error. We need to overhaul the pressure switch, and if it can't be repaired, replace it with a new one;

6. The computer pressure setting value of the air compressor is too low or the pressure transmitter is faulty. First adjust the computer setting value, and do the pressure transmitter, calibration, if the transmitter fails, replace the new product;

7. The load solenoid valve of the air compressor is faulty, and the air leakage causes insufficient control air source. First remove the load solenoid valve for maintenance, and replace it with a new one if it cannot be repaired;

8. The air filter of the air compressor is blocked. Remove the air filter for maintenance first, and replace it with a new one if the filter is blocked;

9. The oil-gas separator of the air compressor is blocked. First, check whether the pressure difference of the oil-gas separator has been reached, and replace it with a new product;

10. The belt of the air compressor transmission is too loose, resulting in a decrease in transmission efficiency. The transmission belt needs to be adjusted, and if it has been damaged, it will be replaced with a new one;

11. The air intake valve coupling of the air compressor is worn and the opening is insufficient. The intake coupling needs to be replaced;

12. The synchronous motor efficiency of the air compressor is reduced, resulting in insufficient opening. The synchronous motor needs to be replaced with a new one).

It shows that the seal between the piston and the cylinder is not tight. It's time to replace the seal.

1. The intake valve is not opened.

When the air compressor is turned on, the internal pressure will be slowly established, when the pressure reaches 5bar (the vast majority of air compressors are like this, except for special), the air intake valve is opened through the solenoid valve control air stopper, and the air compressor sucks in air into the loading state, and the air compressor does not take in air There may be three reasons, the solenoid valve is simple cover friend (circuit, valve body, pipeline), cylinder (valve or diaphragm, seal, pipeline), and intake valve (valve or diaphragm, seal, pipeline) is faulty.

2. False loading of air compressor.

The false loading of the air compressor is mainly due to the failure of the output point of the PLC, the PLC is the loading state of boring operation, due to the failure of the output point, there is no signal to the solenoid valve, resulting in the intake machine not operating. The maintenance of PLC requires professional air compressor maintenance engineers, and non-professionals are not recommended to disassemble at will.

Hello dear! 1. This situation may occur due to the failure of the barometer. At this time, you need to observe the barometer, if it indicates that the pressure is insufficient, you can let the engine run at medium speed for a few minutes, if the pressure still does not rise or rises slowly, if you step on the brake pedal and the deflation sound is very strong, it means that the barometer has been damaged, and the barometer should be repaired.

2. The transmission belt between the air compressor and the engine is too loose or slipped, or the pipeline between the air compressor and the air storage tank is broken or the joint is leaking. At this time, you should check whether the belt of the air compressor is too loose, from the air compressor to the air storage tank when the air compressor is late to the air storage tank, to the control valve inlet pipe, and whether the joint is loose, cracked or leaking. 3. The oil-water separator is resistant to dissipation, and the sediment of the pipeline or air filter is blocked due to too much.

At this time, you should check whether the oil-water separator and the air filter and the dirt in the pipeline are blocked because there is too much, and if it is blocked, the dirt should be cleaned. 4. The exhaust valve of the air compressor is not tightly sealed, the spring is too soft or broken, the cylinder head bolt of the air compressor is loose, and the sand hole and the cover gasket of the cylinder are damaged, resulting in air leakage. At this time, check whether the exhaust valve of the air compressor is leaking, whether the spring is too soft or broken, etc., and replace or repair the damaged parts according to the faults found.

5. The cylinder liner and piston ring of the air compressor are worn out too much and even leak. At this time, check whether the cylinder liner and piston ring of the air compressor are overworn.
