The reasons for the overload of the air compressor can be summarized as follows:
air filter clogging:
when the air filter is clogged, it will hinder the air flow and cause the compressor to overload.
compressor inlet valve failure:
intake valve failure will affect the compressor intake, increase the overload pressure.
oil filter clogging:
the clogging of the oil filter will cause poor lubrication of the compressor, which will cause overload.
Overload protector failure:
when the overload protector fails, the compressor cannot stop automatically, and continuous operation causes overload.
Excessive compressor load:
in the event that the overload protector is not activated, excessive loading may result in an overload.
Input voltage frequency problem:
if the input voltage frequency is not within the corresponding voltage range of the air compressor system, it may also cause overload.
Check valve fault:
when the one-way valve can not play a one-way role, and there is a phenomenon of gas backflow in the gas tank, it will cause the air compressor to overload.
Solenoid valve problem:
if the solenoid valve cannot be unloaded or unloaded for too long after the power is off, it may also cause the air compressor to overload.
Host internal problem:
the deformation of the valve block valve plate inside the main engine or the problem of the main engine bearing, such as the fan blade does not move, may cause the air compressor to overload.
Temperature too high:
the air compressor system or indoor temperature is in a high temperature state for a long time, usually due to long-term continuous operation, which will increase the risk of overload.
Control panel parameters set improperly:
if the parameters of the control panel are not set correctly, it may affect the normal operation of the unit and cause overload.
Running voltage problem:
if the operating voltage of the unit is lower than the rated voltage and exceeds the floating range, it will cause the load to increase, the current will increase, and then cause overload.
Lubricating oil problem:
the amount of lubricating oil is too small or the oil is too poor, will lead to poor lubrication and sealing of the host, increase the screw and bearing wear, resulting in overload.
Oil and gas separator clogging:
the blockage of the oil and gas separator will cause the internal pressure of the machine to increase, increase the load, and cause the machine to overload.
Compressor or motor body fault:
when the machine reaches a certain age or other factors, the bearing is worn and the motor coil is aging, which will also cause the current to increase and cause overload.
In order to avoid the overload of the air compressor, the above components should be maintained and inspected regularly to ensure their normal operation, and the relevant components should be repaired or replaced in time when problems occur.
The working process of the air compressor can be summarized into the following main steps: Start-up phase: The air compressor usually uses the motor start-up method, that is, the motor is started by the motor starter, and then the compressor is driven to work. Air suction and filtration: when the air compressor starts
The replacement cycle of the air filter is not fixed, but is affected by many factors, including the quality of the air filter, the use environment of the air compressor and the air quality. The following is a detailed analysis of the air compressor air filter replacement cycle: the impact of 1. replacement cycle
The gas consumption standard of a food production plant is not a fixed value, but will be affected by a variety of factors, including the production scale of the food plant, the number and type of production line equipment, and the specific production process. Therefore, it is not possible to give a uniform use
The oil content of natural gas compressor is mainly related to the allowable oil content in compressed air, which is very important to ensure the purity of compressed air and the normal operation of subsequent equipment. The following is a detailed analysis of the oil-bearing index requirements for natural gas compressors: 1
The moisture content in the air is not a fixed value, but is affected by many factors such as temperature, humidity, geographical location and climatic conditions. Therefore, it is not possible to give a definite ppm(parts per million, parts per million) value to represent the air.
To determine whether an air compressor is variable frequency or fixed frequency, you can use the following methods: View the control panel or display: The variable frequency air compressor is usually equipped with an advanced control panel or display, which can display the current operating frequency, Pressure and other parameters. and fixed
The air compressor driven by permanent magnet variable frequency has a series of remarkable characteristics, as follows: stable air pressure: due to the stepless speed regulation characteristics of the frequency converter, the permanent magnet variable frequency air compressor can start slowly, and can quickly adjust and respond to large gas fluctuations
Q: How long can the air compressor open? A: Air compressor can be long-term boot operation. Supplement: When the air compressor works together with the air storage tank, the air compressor will stop itself after reaching the set pressure, and the permanent magnet variable frequency air compressor will also run at low frequency to ensure air
The water-lubricated compressor is a special compressor that uses water as the lubricating medium instead of the traditional oil lubrication. When this compressor is running, water will play a role in cooling, sealing and lubrication. Regarding the air moisture content of the water-lubricated compressor, this is a
Oil-free variable frequency screw air compressor has a series of advantages, making it widely welcomed in industrial applications. First of all, due to the oil-free design, this air compressor can eliminate the risk of oil pollution in the compressed air, which is necessary to clean the oil-free air.
