The basic concept of air compressor:
the air compressor is a pressure generating device that converts mechanical energy into gas pressure energy.
use of air compressor:
air compressor is a kind of gas power source conversion equipment, which is used in all aspects of life. In the construction, iron and steel, mining and chemical industrial plants in many uses, especially the twin-screw air compressor is widely used in machinery, metallurgy, electronic power, medicine, packaging, chemical, food, mining, textile, transportation and many other industrial fields, and become the mainstream of compressed air products.
air compressor classification and working principle
there are many types of air compressor, common screw air compressor and piston air compressor
the piston air compressor uses an electric motor or diesel engine to drive the pulley to directly drive the crankshaft through the coupling, drive the connecting rod and the piston rod, and make the piston reciprocate in the cylinder to complete the suction, compression and discharge process.
When the reciprocating piston in the cylinder moves up and down, the pressure in the left cavity of the piston in the cylinder is lower than the normal atmospheric pressure, the suction valve opens, and the outside air flows into the cylinder. This process is called the compression process. When the pressure in the cylinder is higher than the air pressure in the gas pipeline, the exhaust valve opens and compressed air is delivered into the exhaust pipeline. This process is called the exhaust process.
Single-cylinder piston ▼ Double-cylinder piston ▼ Next, the pressure-free or low-pressure gas is boosted and delivered to the gas tank. When the pressure in the gas tank reaches a certain value, the piston air compressor does not stop running but opens the safety valve. No compression operation. Another way is that when the pressure in the gas tank reaches a certain value, the compressor will automatically stop working.
Screw air compressor
it is composed of a group of two parallel screws that bite each other. When the motor drives the two screws to rotate, because the gap between the two screws and the shell is only about 10 wires, the main screw drives the auxiliary screw to rotate together, and the outside air passes through the screw teeth. It is sucked in. As the volume between the teeth of the spiral rotor rotates, the volume between the teeth decreases continuously with the bite of the rotor teeth, and the compressed pressure of the gas increases, when the rotor turns to the same pressure between the teeth and the exhaust hole, the compressed air starts to be discharged.
Condensed water is a big killer of air compressor. If it is not discharged in time, it will rust the inside of the unit, reduce the performance of lubricating oil and affect the operation of the unit. So how is the condensate produced? How to discharge it? Air compressor condensate water mainly comes from the air. Air compressor suction
An air compressor is a device used to compress gas. Air compressors are similar in construction to water pumps. Most of the air compressors that are often seen in life are reciprocating piston type. In recent years, water lubricated oil-free screw air compressors are also on the rise year by year. As an important form of energy generation, air compressor is widely used in
The lubricating oil used in the air compressor generally cannot be replaced by the oil currently purchased on the market. The air compressor must use special lubricating oil, which should conform to the natural environment of the factory and the air compressor model and specification of the air compressor you are applying. Types of air compressor oil on the market, brands
Granklin 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.
One of the two major faults that often occur during the use of screw air compressors is oil leakage. Oil leakage faults are divided into many kinds of organic head oil leakage and shaft seal oil leakage. The rotor of a carbon dioxide screw press in an enterprise is divided into two parts: yin and yang, with a rotating speed of 2157r/min.
Granklin sales of air compressor use the scene is very much, the most common is a variety of air gun tire repair, but the role of air compressor is not only so there are more application scenarios. The role of air compressor.
Air compressor maintenance can find a professional maintenance screw air compressor team. We continuously improve the work flow in screw air compressor maintenance, and can provide air compressor maintenance tutorials, and the main points that need to be paid attention to during daily maintenance.
View detailsThe use of single-screw water-lubricated air compressor, the full name (water-lubricated oil-free screw air compressor) in medical, pharmaceutical, equipment production, oxygen preparation and other eye-catching performance. What is the difference between medical air compressor and industrial air compressor? The main difference is: the gas quality requirements are not the same after the compressed gas needs to be treated
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
It is inevitable that the air compressor will fail during use. We have summarized several common failures of the air compressor, which will definitely help you to quickly troubleshoot and repair the failure. 1. The exhaust temperature of the unit is high (1) The temperature sensor does not work. Countermeasures: replacement is recommended;
