Air compressor use:
1, can be used as air power-air after compression can be used as power, mechanical and pneumatic tools, as well as control instruments and automation devices, instrument control and automation devices, such as machining center tool replacement.
2. It can be used for gas transportation-air compressors are also used for gas pipeline transportation and bottling, such as remote gas and natural gas transportation, carbon dioxide bottling, etc.
3, for gas synthesis and polymerization-in the chemical industry, some gases by the compressor to increase the pressure after the beneficial synthesis and polymerization.
Granklin Group produces the main products, water-lubricated air compressors.
main sales products: water lubricated air compressor, oil-free oxygen (nitrogen) compressor, explosion-proof oil-free compressor, special gas oil-free compressor, screw compressor, refrigeration dryer, adsorption dryer, filter, gas storage tank, etc.
Low maintenance costs
air compressor equipment-screw air compressor original compressor design saves unnecessary maintenance costs. All components are designed for long life, and the large size of the inlet filter, oil filter and fine separator ensure the best compressed air quality. All oil filters and all types of separator components within the 22kW (30hp) are centrifugal open and close, further reducing maintenance time. "Speed up the repair point" so that the repair work can be completed in a few minutes, downtime and maintenance costs greatly reduced.
Built-in intelligent control
to reduce operating costs, precise operational control is essential. All screw compressors are equipped with an intelligent control system, and the control menu is easy to use.
Working principle diagram of screw air compressor
1 Inspiratory process
the screw air compressor has no intake and exhaust valve group, and the intake only depends on the opening and closing of an automatic regulating valve. When the tooth groove space of the main and auxiliary rotors is transferred to the opening of the intake end of the casing, the space is the largest. At this time, the tooth groove space under the rotor communicates with the free space of the intake port. Because the air in the tooth groove is completely discharged during exhaust, when the exhaust is finished, the tooth groove is in a vacuum state, and the outside air is sucked in and flows into the tooth groove of the main and auxiliary rotors along the axis, when the air fills the entire tooth groove, the air inlet side end of the rotor is turned away from the air inlet of the casing, and the air between the tooth grooves is closed. The above is the "suction process".
2 Closure and conveying process
at the end of suction, the main and auxiliary rotor teeth are sealed with the casing, and the air in the tooth groove no longer flows out, that is, the "closed process". The two rotors continue to rotate, their tooth peaks and tooth grooves coincide at the suction end, and the coincident surface gradually moves to the exhaust end, thus forming a "gas transmission process".
3 Compression process and fuel injection process
during the transportation process, the anastomosis surface gradually moves to the exhaust end, that is, the tooth groove space between the anastomosis surface and the exhaust port gradually decreases, the air in the tooth groove is gradually compressed, and the pressure gradually increases, that is, the "compression process". At the same time of compression, lubricating oil is also injected into the compression chamber and mixed with air due to the effect of pressure difference.
4 Exhaust process
when the end face of the exhaust port of the rotor communicates with the exhaust port of the casing (the gas pressure is the highest at this time), the compressed gas starts to exhaust until the matching surface of the tooth peak and the tooth groove moves to the end face of the exhaust end of the casing. At this time, the tooth groove space between the matching surface of the two rotors and the exhaust port of the casing is zero. The "exhaust process" is completed ". At the same time, the length of the tooth groove between the rotor and the housing inlet reaches the longest, thus starting a new compression cycle.

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.
For enterprises to choose low energy consumption, environmental protection of the air compressor is a must, now so fierce competition, the need to control every aspect of enterprise production, in order to bring profits. Permanent magnet variable frequency air compressor has the characteristics of environmental protection and energy saving, which is well known, but the price of equipment with good performance and environmental protection must be expensive?

Choosing the right model can not only greatly reduce the purchase cost of the high-air compressor, but also
The advantages of oil-free air compressor: oil-free air compressor has low noise, which solves noise pollution, and oil-free air compressor solves the phenomenon of compressed gas oil and water. The machine itself contains a water outlet, which can discharge the water in the gas tank. Increased service life. At the same time, the oil-free air compressor does not need lubricating oil, which reduces the cost of purchasing lubricating oil.
Features of water-lubricated oil-free screw air compressor: completely oil-free air quality water replaces oil, realizing the four major effects of lubrication, cooling, sealing and noise reduction, providing high-quality 100 oil-free air without pollution, discharging water without special treatment, and meeting environmental protection requirements.
Air compressor maintenance is not in place will appear a variety of faults, want to quickly solve the air compressor fault needs to find the cause of the fault. The air compressor is still working, but the air supply is insufficient. The air compressor works at a certain pressure and stops the gas tank. In general maintenance of air compressors, we encounter a series of faults such as high temperature shutdown, oil injection from the air inlet of the air compressor, low exhaust pressure, excessive oil and gas emissions from the exhaust valve, etc. When we encounter these faults, we must deal with them step by step.
When used as a process source gas, compressed air is in direct contact with materials and food. When used as a power source, although not in direct contact with food and raw materials, but most of them are used in clean areas. Therefore, compressed air for food must use clean compressed air.
The medical air compressor must be controlled within 60 decibels, and the sound of the general household air-conditioning compressor (about 55 decibels), medical staff will not feel uncomfortable working in such an environment. In view of the relatively quiet environment required by the hospital, air compressors with noise higher than 60 decibels cannot be used in hospitals.
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 outlet of the air compressor. There is also a completely oil-free air compressor, which is not Oil lubrication is used, but water lubrication is used, so the final discharge of gas without oil is called water lubricated air compressor.
