Q: What are the oil-free screw air compressors?
Answer: There are two kinds of oil-free screw air compressors that can be seen on the market at present.
1, water lubrication oil-free screw air compressor, Shanghai granklin group production is this type of air compressor.
2. Dry oil-free screw air compressor.
Because we are the production of such products, so better understanding. There is no lubricating oil in the air compressor head, and water is used to provide lubrication and cooling measures for the air compressor head.
In the industrial production of medicine, electronics, chemical industry, microbial fermentation, blow molding, pressure detection and other industrial production and power stations, 0.3-4.0 MPa compressed air is needed. At present, the screw air compressor is being upgraded and replaced at home and even internationally. The screw air compressor has high working efficiency, low noise, low vibration, convenient maintenance, low operating cost and good air quality. At the same time, the series of machines adopt microcomputer control system, the machine is equipped with pressure, temperature, overload and other multiple protection performance.
Technical Analysis and Selection Suggestions for Permanent Magnet Variable Frequency Air Compressor and Power Frequency Air Compressor In the field of air compression equipment, permanent magnet variable frequency air compressor and power frequency air compressor are like the difference between "smart car" and "traditional fuel car", and their technical characteristics are straight.
In coal mine, air compressor (air compressor) is an indispensable power equipment, mainly responsible for pneumatic machinery to provide power, to ensure the underground air quality, support ventilation and safety system operation and other key tasks, the specific role is as follows: 1. Provide power for pneumatic machinery coal mine
Hospital air compressors play a vital role in the medical field. It is one of the main components of the medical air system and is specifically designed to meet the various needs of the hospital's specific environment. The following is a rigorous description of the hospital air compressor: 1. definition and type of hospital air pressure
The screw rotation speed of screw air compressor is one of the key parameters affecting the performance of the equipment, and its design should consider the factors such as air supply efficiency, energy consumption control and equipment life. Granklin water-lubricated single screw air compressors have been technologically innovative in screw rotation.
Oil-free compressors are widely used in industrial production, and their lubrication methods have attracted much attention. The water-lubricated screw air compressor produced by Shanghai Granklin Group has won wide recognition in the market for its unique lubrication method. Water lubrication is oil-free compression
The principle of permanent magnet variable frequency air compressor is to replace the excitation winding with permanent magnet for excitation. When the three-phase stator windings of the permanent magnet motor (each with a difference of 120 ° electrical angle) are connected to the three-phase alternating current with a frequency of f, a rotation at a synchronous speed will be generated
The difference between power frequency and variable frequency screw air compressor is mainly reflected in the following aspects: power frequency screw air compressor variable frequency screw air compressor working principle The motor speed is constant, and the exhaust volume is controlled by adjusting the opening of the intake valve. When used
In the new energy industry, especially in the fields of battery manufacturing, solar photovoltaic, wind power generation, etc., the oil content of compressed air is very strict. Because the production processes and products in these areas have high requirements for purity, compressed air
Air compressor to prove the cleanliness of the air, can be achieved through a variety of methods and steps. The following are some commonly used methods: 1. use a filter system for multi-stage filtration: oil-free screw air compressors are usually equipped with high-precision filters, which are generally divided
In the air compressor market, the durability of different types of air compressors varies due to multiple factors such as brand, design, manufacturing quality, use environment, and maintenance. As far as Shanghai Granklin Group's air compressor products are concerned, its water-lubricated air compressor, oil-free air compressor,
