intake valve loading principle steps:
1. Start, the motor is turned on, the main engine starts to run, the small hole of the intake valve inhale, 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 main engine head (through the temperature control valve). The pressure rises, part of the pressure is released to the upper part of the intake valve through the vent valve, and the remaining pressure is maintained.
2. Loading, motor star-delta conversion, solenoid valve opening, the pressure in the oil and gas tank reaches the pressure reducing valve through the line, pushing the control cylinder to open the butterfly valve, and the intake valve is fully opened for suction; the vent valve is closed at the same time through the pressure of the solenoid valve, The machine is no longer emptied, and the pressure in the tank continues to rise to the outside air supply.
3. Unload. When the pressure rises to the upper limit of the differential pressure gauge, the differential pressure gauge sends an electrical signal to the solenoid valve. The solenoid valve is closed. If the control cylinder is not under pressure, the butterfly valve is closed to maintain the small hole air intake. At the same time, the vent valve is opened to release the pressure in the oil and gas tank to the basic oil pressure.
4. Stop, the motor stops, the main engine stops and no longer inhales, the lower check valve of the intake valve closes quickly, isolating the inside and outside of the machine, and the vent valve continues to vent to the external atmospheric pressure
We all know that compared with ordinary air compressors, oil-free air compressors have stronger air cleaning capabilities. With the needs of industry production, many factories are now using oil-free air compressors to replace traditional air compressor equipment. Oil-free air compressor brand manufacturers on the market are also
When purchasing water-lubricated variable frequency air compressors, it is also necessary to understand the maintenance of traditional oil-filled air compressors. When you know the maintenance cost of the traditional air compressor and combine the "water lubricated variable frequency air compressor" produced by Shanghai granklin group, you can know how much difference there is in maintenance and whether it is more economical.
View detailsCompletely oil-free gas exists, and the "water-lubricated air compressor" produced by Shanghai Granklin Group is currently popular in the domestic market ". It is fully in line with the conditions of "oil-free lubrication air compressor". The air compressor head is made of stainless steel. When working, the air compressor head is filled with lubricating water. What is it like after the atmosphere is sucked in, and it is compressed and discharged. What kind.
Factory air compressor air pressure setting standards and industry application specifications In the field of industrial production, air compressor as the core power equipment, its air pressure setting should strictly follow the process requirements and safety specifications. Industry practice has proven that the air pressure configuration of the factory air compressor system should follow the following techniques.
Granklin Group is a manufacturer specializing in the production of water-lubricated air compressors. The water-lubricated air compressors we sell are very suitable for medical equipment and hospital oxygen supply. Water lubricated oil-free air compressors are often used in hospitals, laboratories and other industries where the environment is quiet and the quality of the gas source is high.
View detailsGranklin water lubricated oil-free air compressor, through water lubrication, air compressor head operation process, do not need lubricating oil. Compressed air does not contain oil, in order to meet the modern, large-scale safety production.
As we all know, the screw air compressor adopts a pre-set configuration, only a single power connection and compressed air connection, and built-in cooling system, which can greatly simplify the installation work. Its advantage lies in the use of high-capacity compression components, its rotor outer circle speed is low, to achieve a high
[Structure diagram of single screw compressor] [Figure [Analysis Single screw air compressor belongs to positive displacement compressor. By compressing the gas in a variable volume, the volume of this part is reduced and the pressure is increased. The core structure of the compressor is finished by a special machine tool and consists of a screw with six spiral grooves, with one on both sides.
Oil-free air compressor is divided according to whether the compressed air contains oil, which corresponds to oil air compressor or micro-oil air compressor. Oil-free air compressors are distinguished according to different compression forms or different host structures, and manufacturers often choose suitable models according to actual needs. Several common oil-free air compressors are: oil-free piston air compressor, no
Therefore, the suction pressure of the compressor can be appropriately increased, and a high-efficiency cyclone inlet separator can be added in one stage of suction to further eliminate the resistance of the air inlet pipe network, and a higher suction pressure can be obtained while ensuring sufficient processing air. The pressure drop between the 1.2 compressor sections is reduced. The pressure drop between the compressor stages is also an important reason for the power consumption of the compressor.
