Fault shutdowns caused by external components of the controller can be eliminated by checking THIS FAULT or HISTORY FAULT as follows:

Common electrical faults and their causes

It is normal for the screw air compressor to enter the water. Knowing the function and working principle of the water tank and the operation of the machine can provide a buffer space for our screw air compressor, reduce the pulse and stabilize the voltage. , the machine also does not have to restart because of its buffering, reducing power consumption. The following is to answer the water treatment method of the screw air compressor water tank.

A part of the compressed air of the screw air compressor is stored in the air storage tank, and the air contains a large amount of water molecules. When these fast-moving water molecules touch the tank walls, they condense into water. Over time, a lot of water will accumulate at the bottom. Through the working principle, we can know that the water tank is a normal phenomenon. The next step is how to deal with the water. We need to discharge the formed water in time, because it not only affects the air quality, but also rusts the container. Here are three ways to treat this water:

1. A gas-water separator can be installed in the gas storage tank to separate the air in the compressed air.
2. Install an automatic drainage device at the sewage outlet. The selection of an automatic drainage device is also necessary. Poor drainage is easy to block.
3. The pipeline design is reasonable. The compressed air pipeline generally needs to be inclined at about 1 degree. From the system pipeline to the best pipeline, enter the pipeline to the top of the channel, and make a 180-degree elbow down to the gas tank to be imported.

The disconnection of the air compressor is a common fault, and the air compressor has certain hazards and should be paid attention to. While doing daily inspections, regular maintenance and maintenance should also be done, and at the same time, the cooler core should be cleaned, and spare parts should be used as spare parts to ensure the normal operation of the screw air compressor.

Air compressor dripping reasons:

The dripping phenomenon of the air compressor is not easy to be found in time. The dripping phenomenon is generally caused by the unconnected parts or the pressure rise.

Air compressor drip solution:

When the air compressor leaks, the treatment method is basically the same as that of oil leakage. You can refer to the treatment method of oil leakage. However, if there are deep-seated reasons, it is necessary to eliminate hidden dangers and then deal with them according to the deep-seated reasons.

1. It is difficult to judge the noise index, and everyone has different sensitivity to noise:

1). The compressor itself will produce obvious noise due to improper assembly, springs, etc.;

2). In the compressor system, due to the pulsation of the refrigerant flow and the vibration of the pipeline transmission compressor, local resonance may also be caused, resulting in noise. At this time, the resonance point of view can be avoided by adjusting the pipeline, attaching heavy objects (damping blocks) to the pipeline and other measures;

3). To judge whether the compressor noise is high, you can remove the comparison between the compressor and the normal compressor (including no-load and suppressed operation). If there is no obvious difference, you can preliminarily judge the normal noise;

2. The noise of the air compressor is high, and the noise of the compressor can be improved to a certain extent by extending the vacuuming time (40 minutes) and increasing the vacuuming degree.

3. Consultation on the caliber of compressor noise: the size of the sound has its correlation. In a noisy environment and in a quiet environment, we feel the same sound differently. In a quiet environment, it is easy to feel the sound. size. The outside world, so we think the sound of the refrigerator is more obvious at night. In fact, the sound has not changed, but it feels louder.

To avoid noise:

1. The uneven bottom corner indicates that the ground is uneven, and guide the user to adjust the angle of the bottom corner wrench so that the box is in a horizontal position.

2. The box is in contact with other objects or against the wall to guide the user to keep a certain distance from the removed objects or the wall of the box.

3. Then guide the user to tighten the condenser or the water receiving tray when the water receiving tray or condenser is loose, and consult the user in place. 4. When the air compressor starts or stops, the speed of the compressor changes, or from slow to fast or from fast to slow. When the sound change is always greater than the stable time, it is not difficult for us to understand, so you reflect that this phenomenon is a normal phenomenon. affect the normal performance of the machine.

If any abnormal phenomenon occurs during the operation of the compressor, please do not ignore the cause of the phenomenon, but find out and deal with it appropriately.

In order to eliminate possible failures, please read and understand the instruction manual carefully.

A full understanding of the structure and function of the machine is the key to early detection of failures.

This chapter mainly records common faults, causes and solutions. No omissions, but not all failures and how to deal with them are not documented. In addition to the recorded faults and treatment methods, please pay attention to the operators and maintenance personnel to ensure the normal operation of the machine.

TROUBLE SHOOTING LIST

Air compressors have been used in industry for over 100 years because air is a resource that is safe, flexible, clean and convenient. These machines have evolved into highly reliable* devices that are virtually essential in the many applications they serve. Compressors can come in many different types and sizes.

The most common types of compressors in use today are:

Screw compressors

Rotary Sliding Vance Compressor

Reciprocating or piston compressor

centrifugal compressor

Although other types of compressors are also available

Screw compressors work by air filling the gap between two helical mating screws and their casings. As the two helical screws turn, the volume decreases resulting in an increase in air pressure. Most screw compressors inject oil into the bearings and compression areas. The reasons are cooling, lubrication, and creating a seal between the screw and the housing wall to reduce internal leakage. After the compression cycle, the oil and air must be separated before the air can be used by the air system.

Rotary vane compressors such as reciprocating and screw compressors are positive displacement compressors. The compressor pump is mainly composed of rotor, stator and 8 vanes. The slotted rotor is arranged eccentrically within the stator, providing a crescent-shaped swept area between the intake and exhaust ports. Compression is achieved as the volume goes from a maximum at the intake to a minimum at the exhaust as the rotor makes one revolution. The vanes are forced out of the rotor slots and are held against the stator walls by rotational acceleration. Oil is injected into the air intake and along the stator walls to cool the air, lubricate the bearings and vanes, and provide a seal between the vanes and the stator wall. After the compression cycle, the oil and air must be separated before the air can be delivered to the air system.

Reciprocating or piston compressors are the most common machines on the market. They are positive displacement compressors and can be found in the range from small to very high horsepower. Positive displacement air compressors work by filling a chamber with air and then reducing the volume of the chamber (reciprocating, rotary screw, and rotary vane are all positive displacement compressors). A reciprocating compressor works very similarly to an internal combustion engine, but is basically the opposite process. They have cylinders, pistons, crankshafts, valves and housing blocks.

Centrifugal compressors are not positive displacement compressors like reciprocating, screw or vane compressors. They use very high-speed rotating impellers (up to 60,000 rpm) to accelerate the air and then use a diffuser to slow it down. This process is called dynamic compression, and it uses velocity to cause an increase in pressure. In most centrifugal compressors, there are several such impeller/diffuser combinations. Typically, these machines have intercoolers between each stage to cool the air and remove 100% of the condensate to avoid damage to the impeller due to erosion.

Therefore, you need to choose a compressor that suits you, you need to know the gas consumption of your factory, and you need to consult the local AIRERA partners.
