With the development of the times, air compressor as a popular use has become more and more common.
The function and use of the air compressor is that the air compressor can provide power by encrypting the air. After compression, air cannot be used as power, machinery and pneumatic tools, as well as control instruments and automation devices, instrument control and automation devices, such as tool replacement in production centers. Air compressors are also used for liquid pipeline transportation and bottling, such as remote gas and natural gas transportation, chlorine and carbon dioxide bottling.
The principle of air compressor
suction process: The screw-type exhaust side suction port must be designed so that the compression chamber can fully inhale. The liquid ring air compressor does not have an intake and exhaust valve group. The intake is only adjusted by the opening and closing of a regulating valve. When the rotor rotates, the tooth groove space of the main and auxiliary rotors is turned to the intake end wall opening., Its space is the smallest. At this time, the tooth groove space of the rotor is the same as the free air in the air inlet, so the air in the tooth groove is all excluded during exhaust.
When the exhaust is finished, the tooth groove is in a high temperature state. When it is turned to the air inlet, the external air is sucked in and flows into the tooth groove of the main and auxiliary rotors along the axial direction. When the water fills the entire tooth groove, the air inlet side of the rotor turns away from the air inlet of the casing, and the air between the tooth grooves is closed.
Compression process: In the process of gas transportation, the meshing surface gradually moves to the exhaust end, that is, the tooth groove gap between the meshing surface and the exhaust port slowly decreases, and the gas in the tooth groove is gradually compressed and the pressure is strengthened. This is the compression process.
Exhaust process: When the meshing end surface of the air compressor rotor turns to communicate with the casing exhaust, the treated gas starts to be discharged until the meshing surface of the tooth peak and the tooth groove moves to the exhaust end surface. At this time, the area of the tooth groove between the meshing surface of the two rotors and the ventilation port of the casing is zero, thus completing the exhaust method.
As the main gas source of mechanical manufacturing, screw air compressor has been widely used in all walks of life. The "water-lubricated air compressor" produced by Shanghai Granklin Group is an oil-free screw air compressor.
Shanghai Granklin Group produces and sells water-lubricated air compressors. The whole machine is made of stainless steel without lubricating oil and uses water as a lubricant. Introduction to the dry oil-free air compressor: The crankcase of the fully oil-free compressor is of a dry structure. The large connecting rod, small holes, and the front and rear main bearings of the crankshaft generally use double-port sealed grease ball bearings.
According to China Electric Power News Network on September 23, the first centralized compressed air supply project in Shaoxing Binhai Industrial Zone, Zhejiang Province, has officially landed and is about to start construction. After the completion of the project for the surrounding 56 printing and dyeing enterprises to provide nearly 3000 standard cubic meters per minute compression
Human beings basically need food, clothing, housing and travel, of which clothing ranks first. Mention clothing we naturally think of the textile and garment industry. In China's textile and garment industry is very developed. The development of the textile industry is inseparable from the air compressor. It can be said that the screw air compressor is now
View detailsFrom the oil content point of view, the oil and no oil in the air compressor generally refers to the amount of oil in the exhaust port of the air compressor. There is also a completely oil-free air compressor, which is not lubricated by oil, but by water, so the final discharged gas does not contain oil.
There are many types of air compressors, which can be divided into two categories according to their working principles: positive displacement compressors and speed compressors. In the volumetric press machine, the increase of gas pressure is caused by the volume of gas in the sub-press machine being reduced to make the density of air molecules per unit volume.
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.
The wiring is as follows: 1. The three live wires of the air switch are respectively connected to the three inlet ends of the AC contactor of the air compressor, and the three outlet ends are respectively connected to the motor. 2. Any live wire is connected to the coil of a 380V AC contactor, and the other end of the coil is connected to the normally closed contact of the thermal relay.
The water-lubricated air compressor produced by Shanghai Granklin Group is oil-free, environmentally friendly and energy-saving. The whole air compressor is made of stainless steel, so the gas compressed by the air compressor is free of oil. Should the gas storage tank keep up with it?
View detailsAir compressor is the abbreviation of "air compressor. As early as 1640 AD, the first (mechanical) vacuum pump made in Germany, now, with the improvement of technology, air compressors have been busy in all walks of life, such as food, tobacco and other metallurgy, petrochemical, chemical fiber, pharmaceutical and so on.
In order not to affect the production progress of enterprises, most enterprises will be equipped with two screw air compressors, one open and one standby. The standby machine is mainly for emergency use. Only when the gas consumption is not enough or the common machine fails will it be used. Usually it is in a shutdown state, and the number of times it is used is not much. So what should be paid attention to when using the standby machine that is in a state of shutdown for a long time?
