generally, the lubricating oil needs to be replaced after 2000 hours of operation, especially for the first 2000 hours of operation. Specifically, the replacement time can also be shortened and extended according to environmental conditions. But neither should be delayed for too long.
An air compressor is a device used to compress gas. Air compressors are similar in construction to water pumps. Most air compressors are reciprocating piston type, rotating blade or rotating screw. Centrifugal compressors are very large applications.
The compressor is directly driven by the electric motor to make the crankshaft produce rotary motion, and drive the connecting rod to make the piston produce reciprocating motion, causing the cylinder volume to change. Due to the change of pressure in the cylinder, the air enters the cylinder through the air filter (muffler) through the intake valve, during the compression stroke.
Due to the reduction of the cylinder volume, the compressed air passes through the exhaust valve and enters the air storage tank through the exhaust pipe and the one-way valve (check valve). When the exhaust pressure reaches the rated pressure of 0.7MPa, it is controlled by the pressure switch and automatically stops. When the pressure of the gas tank drops to 0.5-0.6MPa, the pressure switch is automatically connected and started.
The air compressor is to provide air source power. It is the core equipment of the pneumatic system. The main body of the electromechanical bleed air source device. It is a device that converts the mechanical energy of the driving force (usually an electric motor or diesel engine) into gas pressure energy. It is a compressed air pressure generator
Screw air compressors are also sold out of stock. Many air compressor manufacturers are even more difficult to find. Spot direct supply of oil-free screw air compressors helps enterprises produce disposable medical masks, N95, N90 and other mask products. Masks used by Chinese people are the responsibility of this year's enterprise. When the production capacity is fully opened, the mask air compressor needs to stock more to prevent birth.
For medicine, food, semiconductor, chemical industry, fermentation and other industries, oil-free and clean compressed air must be the first choice. Oil-free oil-free screw air compressor, water-lubricated oil-free screw air compressor, oil-free scroll air compressor and oil-free centrifugal air compressor are common oil-free. Today, compare two types of oil-free screw air compressors-dry oil-free air compressors and water lubricated air compressors.
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?
View detailsOil-free compressor test machine parameters, screw air compressor test contains what are the main parameters? Especially in the sale of air compressor manufacturers will test the parameters.
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 detailsThe first guarantee is usually 500 hours, that is, the first maintenance of the machine running-in. The first guarantee is relatively simple. It is good to replace the oil and filter. After the maintenance is generally about 2500-3000 hours, but also related to the air compressor site environment, if the site environment
Shanghai granklin group co., ltd. specializes in air compressors. Air compressor accessories of various brands; Cold dryer, suction dryer (compressed air adsorption dryer achieves drying effect through "pressure change" (pressure swing adsorption principle). Since the ability of air to hold water vapor is inversely proportional to the pressure, a part of the dried air (called regeneration gas) is decompressed and expanded to atmospheric pressure. This pressure change makes the expanded air drier, and then allows it to flow through the desiccant layer to be regenerated without air flow (I. e. the drying tower that has absorbed enough water vapor). The dried regeneration gas absorbs the water in the desiccant, take it out of the dryer to achieve the purpose of dehumidification.
Buy products preferred big brand, good service quality manufacturers. From foreign to domestic, there are only a few enterprises that can make water-lubricated air compressors in the screw air compressor industry. "Shanghai granklin Group" is one of them. granklin Do not forget your initiative mind strove forward on the road of water-lubricated air compressors.
Screw air compressor varieties commonly used vocabulary has several "water lubricated air compressor, oil-free air compressor, permanent magnet variable frequency air compressor, power frequency air compressor, air-cooled air compressor, water-cooled air compressor", air compressor specifications
Matters needing attention in the cold winter, if you do not pay attention to maintenance, it will lead to the failure of the air compressor. Therefore, in winter, due to long-term shutdown and no antifreeze protection, the cooler freezes and the body fails when starting
