Oil-free air compressor manufacturer contact:
at present, the main brands of domestic oil-free air compressors are: Granklin and so on.
the principle of oil free air compressor:
when the motor runs, the air enters the compressor through the air filter. The compressor compresses the air. The compressed gas opens the one-way valve through the air flow pipe and enters the air storage tank. The pointer of the pressure gauge rises to 8 Bar.
When it is greater than 8 Bar, the pressure switch will automatically close after sensing the channel pressure, and the motor will stop working. At the same time, the solenoid valve will discharge the air pressure in the compressor head to 0.
At this time, the air switch pressure indicates that the gas pressure in the gas tank is still 8 Bar, and the gas is driven by the ball valve exhaust to work.
When the air pressure in the air tank drops to 5 Bar, the pressure switch is automatically turned on by induction, and the compressor starts to work again.
Air compressor will strive to develop into a new type of machinery manufacturing enterprise with equipment, technology, management, excellent products and customers. shanghai granklin group air compressor involved in business sales of water lubricated air compressor, water lubricated single screw air compressor, water lubricated screw compressor, oil free air compressor for sale, screw compressor, screw air compressor and so on.
In fields such as biology, medicine, electronics, food, medical, automotive, chemical, etc., the water, oil, dust, bacteria, etc. in the compressed air are required to reach a high quality level. However, the water, dust, and bacteria in the compressed air can be passed through a series of filters and dryers.
For ordinary production industries, the requirements for air compressors are not very strict. At this time, you can choose an air compressor with oil or micro-oil. After all, the cost of an air compressor with oil or micro-oil is different. And for some of the air compressor requirements are more stringent enterprises, such as laser cutting, medical and other industries, will be more stringent requirements on the air compressor, the need for air compressor can reach the standard of oil-free. This time to choose an oil-free air compressor.
The primary maintenance of screw air compressor mainly includes the following contents and steps: 1. Check the joint contact and insulation resistance of the electrical part of the air compressor. First, use an ammeter to detect the current value of each item or use an infrared temperature measuring gun to detect the incoming terminal temperature. Do
First of all, the material of the machine itself does not contain oily substances, and there is no need to add any lubricating oil when working, so the quality of the discharged air is greatly improved, and the safety of the equipment required by the user is also guaranteed. Unlike an oil air compressor, the discharged gas contains a large amount of oil molecules.
Note: 1, the use of oil-free air compressor must absolutely comply with safety matters, in case of fire, electric shock, personal injury and other accidents. 2, keep the workplace clean; chaos can easily lead to accidents. 3, pay attention to work
If you determine the size and type of compressor, but there is a problem is the choice of oil lubrication or oil-free air compressor. In order not to make the answer too complicated, your choice should be based on the application of compressed air. Do I need an oil-free compressor?
Screw air compressor pumping slow how to deal with, screw air compressor pumping slow power generally have the following reasons: screw air compressor pumping slow how to deal with? 1, the host problem. Check the air supply power of the equipment host, and close the valve behind the air tank
There are too many brands of oil-free air compressors. It depends on your specific needs, such as power/exhaust volume/exhaust pressure, which are all related to the price of oil-free air compressors. When buying a full oil-free air compressor, you can understand the advantages and disadvantages of different air compressor products. It is very important to choose a suitable air compressor brand. As a domestic brand, the water lubricated air compressor produced by Shanghai Granklin Group has a much lower market price than the imported brand, which is a better choice.
