Air compressor can not hit the gas may be caused by a variety of reasons, the following are some common reasons and their brief description:
Pipeline leakage: If there are cracks, loose joints or poor sealing in the air intake pipeline of the air compressor, it will cause gas leakage, which will affect the air intake of the air compressor.
Air filter clogging: When the air filter is filtering impurities in the air, if it is not cleaned or replaced for a long time, it will easily be blocked, resulting in poor air entry, which will affect the air intake efficiency of the air compressor.
Intake valve failure: The intake valve is responsible for controlling the inflow of gas. If the intake valve cannot be opened or closed normally, it will affect the intake of the air compressor.
Head failure: The head is the core component of the air compressor and is responsible for compressing the gas. If the head is worn, damaged or malfunctioning, the gas compression efficiency will be reduced, which will affect the air output of the air compressor.
Piston or cylinder damage: For piston air compressors, if the piston ring is severely worn or the cylinder is not tightly sealed, it will cause gas leakage, which will affect the compression efficiency of the air compressor.
Yin and Yang rotor wear: for the screw air compressor, the wear between the Yin and Yang rotor will lead to an increase in internal leakage, thus affecting the air output of the air compressor.
Pressure switch failure: The pressure switch is responsible for controlling the start and stop of the air compressor. If the pressure switch fails or is set incorrectly, the air compressor will not be able to correctly sense the current air pressure, thus affecting its working state.
PLC output point failure :PLC is the control center of the air compressor. If its output point fails, it may cause the air compressor to fail to perform loading and unloading operations correctly, thereby affecting the air output.
Minimum pressure check valve failure: This valve is used to prevent gas backflow. If the minimum pressure check valve fails, the gas may not be discharged smoothly or return to the inside of the air compressor, thus affecting the gas output.
Power failure: power supply problems such as abnormal power supply lines, blown fuses, and circuit breaker trips may cause the air compressor to fail to start or operate normally.
Motor failure: The motor is the power source of the air compressor. If the motor fails (such as phase loss, burning, etc.), it will affect the normal operation and air output of the air compressor.
Condensate discharge is not smooth: Condensate water deposited in the air compressor may affect the flow of gas and compression efficiency.
Gas consumption increases. With the increase of production demand, the gas consumption may gradually exceed the rated output capacity of the air compressor, resulting in the air compressor not being able to breathe.
in summary, the reasons why the air compressor cannot be inflated may involve the intake system, compression system, control system, and other common problems. In actual operation, investigation and solution should be carried out one by one according to the specific situation. If you cannot solve the problem by yourself, it is recommended to contact professional maintenance personnel for inspection and repair.
A variable frequency air compressor and a fixed frequency air compressor are configured in a compressed air system at the same time, mainly to balance operating efficiency, stability, cost and flexibility, and to achieve complementary advantages through the cooperative work of the two to meet different Gas demand under working conditions. The following
Compressed air is widely used in the semiconductor industry, mainly in the following aspects: Cleaning and cooling equipment: Since the tiny particles and moisture in compressed air have been removed, it is very suitable for cleaning the surface and internal of semiconductor equipment
Mobile air compressors are not considered special equipment in most cases. Special equipment refers to those related to life safety, dangerous equipment, such as boilers, pressure vessels (including gas cylinders, the same below), pressure pipes, elevators, lifting machinery, passenger transport
The inspection cycle of the air compressor needs to be considered according to various factors such as equipment type, frequency of use, working environment and manufacturer's recommendations. The following is some detailed information about the air compressor inspection cycle: 1. comprehensive inspection cycle according to industry standards
If the screw air compressor does not open and run for a long time, it may produce a series of adverse consequences, including the following: internal dust and pollution: dust, oil and other impurities may accumulate inside the screw air compressor for a long time. These pollutants will not only
There is no direct difference between oil-free air compressors and oil-free air compressors in terms of durability. They have different characteristics and application scenarios, so which is more durable depends on the specific use environment and maintenance conditions. The advantage of oil air compressor is
Semiconductor test plant compressed air dryness In a semiconductor test plant, the dryness of compressed air is a crucial parameter. Because semiconductor devices are extremely sensitive to moisture and other contaminants in the environment, highly dry pressure must be used.
In the field of oil-free air compressors, the oil content of the gas is a crucial indicator, which is directly related to the purity of the compressed air and the applicability of the application field. The water-lubricated screw air compressor produced by Shanghai Granklin Group has demonstrated excellent performance in this regard.
The role of compressed air in the operating room: In the operating room, compressed air plays a vital role. It is mainly used to drive various medical equipment and tools, such as scalpels, drills, saws, staples, etc. It also provides clean and dry space for the operating room.
The main reasons why it is not recommended to use compressed air blowing equipment in the production line are as follows: 1. compressed air quality problems Compressed air may contain moisture, oil, dust and other impurities in the manufacturing process. If you use unfiltered and dried compressed air directly
