1. Check whether the fuse is burned and blown, causing the circuit to fail and cannot be powered on.
2. Motor failure. The insulation layer is aged or the temperature is too high, the insulation layer is melted, so that the insulation effect is insufficient and leakage occurs.
3. The motor is locked and overcurrent. Insufficient lubricant, or foreign matter stuck in the nose, so that the current is too large to start.
4. PLC control failure. The program may have wrong code, garbled code; or electrostatic failure, so that the element circuit failure.
5. The contactor or frequency converter is burned. Internal components contact, poor work, electric shock melting, "arc".
6. Sensor failure. The pressure sensor or temperature sensor may be in poor contact, the wiring is reversed or even damaged, which will cause it to fail to start. At this time should contact with professional after-sales personnel maintenance matters.
7. Check whether the power supply voltage is normal. The supply voltage of the screw air compressor is too low, and the undervoltage of the power supply will cause it to fail to start.
8. Check all wiring ports to see if they are loose and tightened.
Air compressor is an air compressor, which is a device that provides compressed air for the production and manufacturing of enterprises. It compresses the atmospheric air sucked from the outside to make it have a certain pressure and is widely used in all walks of life. The importance of compressed air is self-evident, equipment start-up, mechanical operation, production work, etc. are inseparable from the compressed air. If the air compressor can not start, the user will be very upset, will affect the smooth progress of the production work. The main reasons why the air compressor cannot be started are as follows:
electrical aspects: first check whether the power supply wiring of the air compressor is correct, whether the power switch is correctly closed, whether the power fuse is blown, and whether the power supply voltage reaches 90% or more of the rated voltage. Check whether the components of the pressure relay of the air compressor are damaged and whether the given value of the pressure relay is appropriate.
Operation fault: when starting, the outlet switch is not opened, the pressure of the outlet is set too high, the switch is not restored after the electrical circuit, and the setting of voltage and current is unreasonable.
The general screw air compressor has an automatic protection device, so when some parts of it fail, it cannot be started normally. Start, stop control loop, due to more electrical components, more control points, the failure rate is relatively more. Start button, stop button or switch, etc., due to improper operation, may cause the host can not start or fault shutdown. Common mechanical faults that cause the air compressor to fail to start normally include: start button, stop button, emergency stop button, control panel failure, etc. If you do not pay attention to the operation, the button will be stuck on the edge of the button shell and cannot be reset.
Granklin Group is a domestic manufacturer of self-produced water-lubricated air compressors. We can achieve a pressure of 0.15-4Mpa. Water-lubricated air compressors can provide pure oil-free compressed air for enterprises. Energy saving inverter control of the air compressor and the traditional control of the air compressor, the energy saving version is the most important and the most important, according to the demand for compressed air to adjust the supply of air compressor running state.
View detailsAir compressor is one of the main mechanical power equipment of many enterprises, and it is very necessary to maintain the safe operation of air compressor. Strict implementation of the air compressor operating procedures will not only help extend the service life of the air compressor, but also ensure the safety of the air compressor operator.
Water lubricated oil-free air compressor is generally a single screw air compressor, single screw water lubricated oil-free air compressor is used for compressor lubrication medium is water, using water as a seal, completely oil-free, pure oil-free compressed air, completely changed the production environment of some industries.
View detailsThe specific application of screw air compressor in food and pharmaceutical fields, the application of air compressor in various industries is very extensive, but the requirements of different industries for screw air compressor are also different. The application and light of screw air compressor in food and pharmaceutical fields are introduced in detail below.
There is a complete set of procedures for the installation of screw air compressors. Although the standards of various manufacturers are different, the general steps are similar. On the basis of summarizing the installation and debugging experience of many air compressors, the author now writes down the general steps and matters needing attention in an article to provide reference for peers to smoothly carry out the installation and debugging of air compressors.
A large amount of condensed water will be produced during the working process of the air compressor, which must be discharged in time in order not to affect the normal operation of the unit. There are two main ways of condensate discharge, manual discharge and automatic discharge. Manual discharge has a disadvantage. If the staff forgets to discharge, it will lead
If the permanent magnet air compressor condensate is not discharged for a long time, it will cause rust inside the unit, reduce the effect of lubricating oil, and affect the operation of the air compressor. In summer, it will even cause the air compressor to start and stop constantly. So what is the basic principle of this air compressor?
The screw air compressor is an oil-injected single-stage twin-screw compressor. It adopts high-efficiency pulley transmission to drive the main engine to rotate for air compression. The compressed air in the main engine is cooled by oil injection. The air and oil mixed gas discharged from the main engine are coarse and fine. Two separate
When we choose an oil-free water-lubricated air compressor, in addition to conventional parameters such as displacement and power, we generally pay attention to its cooling method. Generally, there are two main cooling methods for an oil-free water-lubricated air compressor: water-cooled and Air-cooled, then these two cooling methods
Why choose granklin oil-free permanent magnet air compressor? Permanent magnet air compressor, as the name suggests air compressor using permanent magnet motor drive, from the largest energy consumption of the motor to reduce the power consumption of air compressor. What are the advantages of using a permanent magnet motor air compressor? In terms of energy consumption, we all know that permanent magnet motors combined with variable frequency controllers, air compressors can supply
