the screw air compressor is not loaded with air, which is one of the common faults of the equipment. In case of this kind of failure, it is necessary to investigate the causes step by step. Generally, the reasons for the screw air compressor not being loaded are nothing more than the following:
1. Intake valve is not open:
after the air compressor is turned on, the internal pressure will be slowly established. When the pressure reaches 5Bar, the solenoid valve controls the cylinder to open the intake valve, and the compressor sucks air into the loading state. There may be three reasons why the air compressor does not enter the air. The solenoid valve (circuit, valve body, pipeline), cylinder (valve plate or diaphragm, seal, pipeline) and intake valve (valve plate or diaphragm, seal, pipeline) are malfunctioning.
2. Failure of pressure check valve:
screw air compressor pressure check valve is easy to judge whether there is a failure, when the pressure inside the machine is too high, but there is no pressure output, you can judge the pressure check valve failure. If the pressure check valve fails, it needs to be replaced with a new one.
3. False loading of air compressor: The main reason for the false loading of air compressor is the failure of the output point of PLC. PLC is in a running loading state. Due to the failure of the output point, no signal is given to the solenoid valve, resulting in the air intake machine not operating. PLC maintenance to professional air compressor maintenance engineers, non-professionals are not recommended to disassemble.
4. Air compressor host failure:
the failure of the main engine of the air compressor is relatively complicated. The wear of the yin and yang rotors or the lubricating oil of the air compressor will cause the failure of the main engine. If the main engine fails to load, you can find professional air compressor maintenance personnel.
Intake valve loading principle steps: 1, start, the motor is turned on, the host starts to run, the intake valve hole suction, the check valve is opened, the compressed oil and gas enter the oil and gas tank, and the lubricating oil in the oil and gas tank is sprayed into the host head (After the temperature control valve). The pressure rises and part of the pressure passes
Oil-free water lubrication screw air compressor has always enjoyed a high reputation in the market. The frequency conversion oil-free system selected by the device can not only reduce the oil content in the compressed air, but also be stable in use. Therefore, the correct use of oil-free air compressor has also become a lesson of concern to users.
The current of the 1. oil-free air compressor is too high: the common reasons for this failure are as follows: 1. The main engine fails 2. The exhaust pressure is too high 3. The voltage is too low: Generally, the power of the oil-free air compressor is Rated, therefore, according to the public
Food, medicine, textile, chemical and other industries with high gas requirements, oil-free air compressors are gradually recognized by enterprises and widely used by more and more companies.
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?
Water lubricated air compressor routine maintenance costs, compared to the oil screw air compressor maintenance costs are much lower, why? As we all know, there is oil screw air compressor lubricating oil, a barrel of oil is very expensive, including labor costs, parts costs, or occupy a large enterprise expenses. The account is not unknown, the water lubricated air compressor only needs
The specific application role of air compressors in various industries? Air compressors are used in electric power, textile, steel, food, pharmaceutical, breathing, diving, fire fighting, electronics, machinery, equipment, automobiles, packaging, printing, toys, chemicals, energy
Speaking of how much is the water-lubricated oil-free air compressor? This problem, granklin's Shen is a professional counterpart. The main product of our Granklin Group is the water-lubricated oil-free air compressor. Under this topic, Granklin Group, as a senior enterprise in the industry, still has a little experience.
In recent years, the biggest black horse in the screw air compressor market (water lubricated screw air compressor) is a new type of air compressor equipment. Whether it is working principle or lubrication method, it is quite different from the traditional screw air compressor. shanghai granklin group for your detailed introduction under the oil and water lubrication screw air compressor working principle and advantages.
View detailsWith the development of science and technology, the requirements for mechanical equipment in industrial production are getting higher and higher. Now many enterprises are using oil-free air compressors to replace traditional air compressor equipment in order to ensure the quality of production. However, oil-free air compressor equipment and ordinary air compressor equipment
