There may be many reasons for the difficulty of starting the screw air compressor. The following are some common reasons and solutions:
electrical fault:
the power supply voltage is unstable or the voltage is low, resulting in insufficient starting current. Check whether the power supply voltage is stable, and ensure that the cable line is not aging or poor contact.
The motor coil is shorted or open. It is necessary to check the wiring and insulation status of the motor winding, and ensure that the motor rotor is running well, and repair or replace the faulty motor if necessary.
Mechanical failure:
valve failure, such as the valve cannot be opened or closed tightly. Check and repair or replace the valve in question.
The head of the screw air compressor is stuck by foreign matter, or the current is too large due to insufficient lubricating oil. Foreign bodies should be cleaned up and sufficient lubricating oil should be ensured.
Other reasons:
the fuse is burned out, causing the circuit to fail to connect, and the fuse needs to be replaced.
Contactor or converter damage, such as poor contact of built-in parts or electric shock melting, should be repaired or replaced.
PLC control failure, may be due to program errors, garbled code or electrostatic failure, the need for professional maintenance.
Sensor failure, such as force sensor or temperature sensor poor contact or damage, should contact professional after-sales personnel for maintenance.
Please note that the reasons listed above are only common faults that may cause difficulty in starting the screw air compressor. Actual conditions may vary depending on factors such as equipment model, use environment and maintenance conditions. When encountering difficulties in starting, it is recommended to check the basic conditions of the power supply and voltage, motors and mechanical parts first. If the problem cannot be solved, you should contact professional after-sales service personnel for further diagnosis and maintenance.
In addition, regular maintenance and maintenance is also very important to prevent the screw air compressor from starting difficulties. By keeping the equipment clean, lubricated and tight, the service life of the equipment can be extended and the possibility of failure can be reduced.
Generally, the air pressure of compressed air will be determined according to the specific application requirements and equipment specifications. The following are the air pressure ranges of compressed air in some common scenarios: routine applications: in routine applications, the pressure of compressed air is usually between 0.4MPa and 1.0MPa
How long can an oil-free air compressor that operates all the year round last? Sometimes, after an air compressor leaves the factory, it is not that the expected service life is not reached, but that the user purchases parts other than the manufacturer to replace, then the machine is out of protection. At this time manufacturers will be depressed, the factory choice of oil-free air compressor parts are carefully selected, users may choose third-party procurement. This is rare for large enterprises, most of which are small factories that purchase parts from outside the manufacturer.
View detailsIn semiconductor manufacturing, the cleanliness of compressed air directly determines the yield and product reliability of chip production. Its core requirements can be summarized as follows, which are explained in combination with the technical characteristics of water-lubricated air compressors: 1. cleanliness core requirements particulate matter control
The displacement on the nameplate of the air compressor refers to the air volume discharged by the air compressor per unit time and converted into the suction state. This is a key indicator to measure the performance of an air compressor, indicating the volume that a piston can discharge from one stroke to another.
The "8 pressures" marked by the air compressor usually refers to the maximum working pressure that the air compressor can produce, and this pressure value is measured on the basis of atmospheric pressure. In general, one atmosphere is equivalent to about 101.32 5千帕(kPa)
Analysis of the relationship between gas purity and dew point in semiconductor manufacturing In the field of semiconductor manufacturing, gas purity and dew point are the core parameters that affect product quality, process stability and equipment life. The two form a direct correlation through the water vapor content, which together constitute a semiconductor.
When choosing whether to equip one air compressor with frequency conversion and the other with no frequency conversion, you need to consider multiple factors, including usage scenarios, cost-effectiveness, equipment performance, and maintenance requirements. Here are some suggestions to help you make an informed choice: 1. make
In the highly sophisticated field of chip packaging, compressed air is an indispensable role! However, the compressed air here is not of any quality, especially for its oil content, which has strict requirements! Imagine that,
Compared with the power frequency air compressor, the variable frequency air compressor has significant advantages in energy saving. Specifically, the frequency conversion air compressor can save about 20% to 40% of the electric energy compared to the power frequency air compressor. This energy saving effect is mainly due to the adaptive adjustment of the variable frequency air compressor when the load changes.
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
