The oil-free screw air compressor in the factory usually needs to run all day and consume a lot of electricity. Advanced frequency conversion technology not only helps to save energy, but also makes the operation of the air compressor simple and stable. So in the choice of oil-free screw air compressor inverter should pay attention to what?
Operating frequency
the high power range of the air compressor inverter is 60Hz to 400Hz. A low frequency converter means that the motor runs at a low speed. When the motor works at low speed, the current increases, which is not conducive to heat dissipation. Similarly, high frequency operation will also cause damage to the motor, and in severe cases, it will burn the motor.
Motor Nameplate
look at the nameplate of the motor, you can clearly see the power, current, voltage, speed, and frequency of the motor.
Torque constraints
the torque constraints include a driving torque constraint and a braking torque constraint. The drive torque constraint ensures that the air compressor inverter will not trip when the load torque increases. Braking torque constraints ensure that the motor can decelerate to rest without tripping when decelerating without braking resistance.
with the continuous progress of science and technology, the frequency conversion technology of oil-free screw air compressor is gradually popularized and improved. When choosing a frequency conversion oil-free screw air compressor, pay attention to the parameters of the frequency converter.
Oil-free air compressors are widely used in textile, energy, transportation, food, petrochemical and machinery manufacturing industries. With the development of the current industry, less and less oil compressors are used. As people's requirements for the environment and noise are getting higher and higher, the traditional oil noise is loud, and the compressed air is air with different oil content, but the manufacturing cost is low and the pressure is high, compared with the oil-free air compressor, the manufacturing cost is relatively high, so it is more expensive.
However, granklin oil-free air compressor adopts self-produced water-lubricated air compressor main machine, all copper wire winding, small starting current, strong power, continuous constant pressure work adopts imported SKF double row automatic self-aligning bearing, which can bear high radial load, optimized contact profile of roller and raceway, and optimized contact design of large end face of roller and large gear and side guide face, effectively eliminating edge stress, and can more effectively reduce bearing temperature rise, it is better than ordinary oil-free air compressor, and the price difference is not very big.
Good or bad depends on the occasion of use and the actual working conditions. In some cases, such as food, medicine, precision instruments and other industries, it is necessary to use a full oil-free air compressor. But the whole oil-free air compressor is much more expensive and the maintenance cost is higher. If it is used to blow
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.
The "air compressor head" produced by "Shanghai granklin group" is used in the "water lubricated air compressor" produced and sold by itself. for the "air compressor head", an enterprise specializing in the production and manufacture of "granklin air compressor", we strictly control the quality of the "air compressor head" under the condition of completely using the self-produced "air compressor head.
What is the price of oil-free and water-free air compressor? Oil-free air compressor does not contain a drop of oil during compression. The air compressor head needs cooling and lubrication, and water is used as the lubricating medium. This effect can be achieved very well. Industrial production often needs to be matched with post-treatment such as cold dryer, suction dryer, precision filter, air storage tank, etc.
Medical air compressor, the requirements are very strict, of course, is to choose stable quality, reliable equipment. At present, domestic oil-free air compressor can consider Granklin air compressor, and it is certainly not wrong to choose a big brand. Granklin air compressor has a great scope of application, meeting different industries
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 the compressed air can not be used as power, mechanical and pneumatic tools, and control
Can the compressed air of the water-lubricated air compressor be used directly without treatment? The exact answer is no. The air compressed by the air compressor is cooled by the rear cooler. After the air-water separator is separated and the buffer tank is stabilized, it is generally in a saturated state. Its relative humidity is 100, and there will be impurities such as solid particles. This compressed air cannot be used directly and needs to be dried and purified.
The water-lubricated air compressor uses water to lubricate the head of the air compressor. The whole machine is made of stainless steel, and the compressed gas does not contain oil. Shanghai Granklin Group, the production of [water lubricated air compressor] in the summer is as low as possible to run [oil-free air compressor]];
"Air compressor" is mainly used to pressurize gas and some transportation and other operations of the machine. The general structure of the "air compressor" is similar to the water pump we are familiar with. It is widely used in many production and manufacturing industries. The "air compressor" also has many unique functions and uses.
The water lubricated air compressor produced by granklin group has a pressure range of 0.15-4Mpa. the exhaust flow rate is determined by the amount of air used to purchase the most appropriate number of machines. When installing the water-lubricated air compressor, the best configuration is to use stainless steel gas storage tanks, pipes, filters, etc.
