The water-lubricated air compressor produced by Shanghai Granklin Group is suitable for compressing nitrogen, argon, natural gas and other gases in safety and explosion-proof treatment. Safety explosion-proof air compressor Granklin Group has rich experience and can work stably for a long time in various scenarios.
Screw air compressor is a kind of air compressor, there are two kinds of double screw air compressor and single screw air compressor. The invention of the twin screw air compressor is more than ten years later than the single screw air compressor, and the design of the double screw air compressor is more reasonable and advanced.
single screw air compressor is also called worm air compressor. The meshing pair of single screw air compressor consists of a 6-head screw and 2 11-tooth star wheels. Screw compressor is a working volume for rotary motion of the volumetric gas compression machinery.
The compression of gas depends on the change of volume, and the change of volume is achieved by the rotary motion of a pair of rotors of the compressor in the casing.
The vulnerable parts of the main engine of the screw air compressor mainly include: gaskets, sealing rings, shaft oil seals, etc., especially the shaft oil seal, which is exposed to high temperature, high pressure, and high-speed working environment for a long time, and its service life ratio is shortened.
The screw air compressor has a rated power. If there is a container for storing compressed air, and the pressure in the container is less than the rated pressure of the air compressor, the air compressor will work. When air is not used, when the air compressor reaches the rated power, the air compressor will stop.
the direct result of its damage is the formation of compressor oil leakage, if not found in time, it will form a yin and yang rotor and bearing due to the lack of smooth and burned. Deformation of components.
When there is an air storage tank, even if the air compressor is stopped, the compressed air can be used as usual, because the compressed air is stored in the air storage tank. The screw air compressor starts frequently, and the motor starting current is very large. Generally, the starting current is higher than the normal working current, and then the energy consumption is relatively large.
Screw air compressor in the start and stop process, the air compressor is in no-load state. If this process is long, it will waste a lot of energy. With an air system equipped with an air storage tank, the air compressor can be stopped under a stable pressure, which not only ensures the continuity of work, but also prevents the machine from wasting energy due to unnecessary idling.
Assuming that the screw air compressor displacement is 2 cubic meters, if the company's gas consumption is relatively large, it is recommended to buy 2 cubic meters of air storage tanks, so that the air storage tank can be filled in a short time and reach the rated pressure. Generally, according to the different production needs and gas consumption of each enterprise, you can decide how many gas tanks to use.
Contemporary screw air compressor not only uses the traditional screw, its structure, technology, but also uses a variety of materials, design and manufacture of a wide range of equipment models, the use of advanced technology developed products, so that a certain amount of screw and other materials can meet the user labor, production
What brand of water-lubricated oil-free air compressor is good? Purchase oil-free air compressor to choose Shanghai Grankering Group, odorless, colorless and tasteless products. Can also be used in the cosmetics and manufacturing industry, in line with the European registration requirements.
View detailsSmall air compressor common piston air compressor, screw air compressor, screw air compressor miniaturization integration in today is also very common. The 5.5KW screw air compressor is a small product. The small water-lubricated air compressor produced by Shanghai Grank Group has stable gas supply and no oil. Many small businesses, as well as laboratories and other users are very fond of purchasing small air compressors.
View detailsSingle screw air compressor is now the air compressor industry leader, its working principle is better than the twin screw air compressor. Shanghai granklin group (water lubricated oil-free single screw air compressor) production plant. Those who need to see the goods and visit can visit our company at any time.
View details"7.5kw air compressor" in the industrial "industrial screw air compressor" is not big, because as "Shanghai granklin group" production of a larger "air compressor", it has the characteristics of simple maintenance, stable gas supply. Small "air compressor" models are more popular in small and medium-sized enterprises, especially "7.5kw air compressor".
Screw air compressor: There is a pair of rotors inside the screw air compressor, and they are toothed with each other. The working cycle can be divided into three processes, namely suction, compression and exhaust. As the rotor continues to rotate, the intermeshing teeth complete the same duty cycle. vortex air pressure
Several advantages of oil-free air compressor, as well as the difference between oil-free air compressor and oil-free air compressor. Specifically, look at their differences: oil and no oil in the air compressor generally refer to the amount of oil content in the gas discharged from the exhaust port of the air compressor. Generally, the oil content of the oil machine is relatively large, and the oil content of the oil-free oil machine is 0.01ppm, so this oil content is used to distinguish the oil and no oil in the air compressor. There is also a full oil-free air compressor, it is not the use of oil lubrication, but the use of water lubrication, so the final discharge of the gas does not contain oil called full oil-free air compressor.
Now it has entered the summer that people love and hate, and the temperature in many places has risen to above 30°C. In the face of the hot summer, screw air compressor temperature is too high by what reason? Summer, screw air compressor is more common fault is scattered
The first reason for the failure of the shutdown of the air compressor is: the exhaust temperature of the unit is high 1, and the lubricating oil level of the machine is low; Solution: Add oil to the 1/2~2/3 position of the sight glass. 2. The cooling fan is not working properly; Solution: Troubleshoot the fan
What are the common shortcomings of the screw air compressor?(1) When the screw air compressor is shut down, the air inlet is sprayed outward. When the air compressor suddenly stops and does not open the exhaust valve in time to discharge exhaust gas, the air inlet sprays cooling oil outward. At this time, first check whether the intake valve has defects and cannot be closed normally. Second, check whether the oil cut-off solenoid valve has defects. Assuming it is normal, further check whether the check valve on the main exhaust pipe can be closed in time or completely. If there are defects, it should be removed.
