intake valve loading principle steps:
1. Start, the motor is turned on, the main engine starts to run, the small hole of the intake valve inhale, the check valve is opened, the compressed oil and gas enter the oil and gas tank, and the lubricating oil in the oil and gas tank is sprayed into the main engine head (through the temperature control valve). The pressure rises, part of the pressure is released to the upper part of the intake valve through the vent valve, and the remaining pressure is maintained.
2. Loading, motor star-delta conversion, solenoid valve opening, the pressure in the oil and gas tank reaches the pressure reducing valve through the line, pushing the control cylinder to open the butterfly valve, and the intake valve is fully opened for suction; the vent valve is closed at the same time through the pressure of the solenoid valve, The machine is no longer emptied, and the pressure in the tank continues to rise to the outside air supply.
3. Unload. When the pressure rises to the upper limit of the differential pressure gauge, the differential pressure gauge sends an electrical signal to the solenoid valve. The solenoid valve is closed. If the control cylinder is not under pressure, the butterfly valve is closed to maintain the small hole air intake. At the same time, the vent valve is opened to release the pressure in the oil and gas tank to the basic oil pressure.
4. Stop, the motor stops, the main engine stops and no longer inhales, the lower check valve of the intake valve closes quickly, isolating the inside and outside of the machine, and the vent valve continues to vent to the external atmospheric pressure
Screw air compressors are increasingly used in all walks of life. Enterprises have been looking for better air compressors, hoping to purchase air compressor products with higher efficiency, fewer failures and lower maintenance rates. The oil-free air compressor produced by Shanghai Granklin Group is modular, streamlined in structure and stable in gas supply. It is a product that has won unanimous praise from users.
View detailsPrecautions for dry oil-free air compressor: 1. Safety matters must be observed during use to prevent fire, electric shock, personal injury and other accidents. 2, keep the workplace clean; chaos can easily lead to accidents. 3, pay attention to the workplace environment: air compressor can not let the wind and rain, do not work in damp and dark places, do not work in the storage of flammable and explosive liquid gas and dusty places.
In recent years, the voice of energy saving and emission reduction in China is getting higher and higher, and the demand for energy-saving equipment is also increasing. Increasing energy conservation has also become a realistic task facing the air compressor industry. Frequency conversion air compressor is an energy-saving air compressor, its advantages are as follows: advantages: set the pressure at will, and maintain a constant pressure. Oil-free air compressor is suitable for: municipal, mining, tunnel, exploration, petroleum, wharf, shipbuilding, power plant, drilling, steel plant, subway, highway, railway, airport, factory, hospital, ship, building, communication, mining, pipeline cleaning, construction machinery and other fields.
shanghai oil free screw air compressor quotation? procurement of oil free air compressor quotation consulting! water lubricated air compressor quotation, air cooled air compressor quotation, frequency conversion air compressor how much money? screw air compressor is one of the air compressor. The single screw air compressor is composed of a cylindrical screw and two symmetrical arrangement of the plane star wheel meshing
The trend of the air compressor market is also filtered to the permanent magnet frequency conversion and two-stage compression. Permanent magnet frequency conversion, the biggest feature is energy saving. As long as the user's gas consumption and gas consumption status is not always in a full load state, permanent magnet frequency conversion products can achieve the actual energy saving effect.
The traditional "oil-injected screw air compressor" in the development of "water-lubricated oil-free air compressor", the impact is not small, users due to the upgrading of enterprise product lines, more inclined to use "water-lubricated air compressor", or similar "oil-free air compressor". The construction of a civilized city proposed by the state has higher and higher environmental protection requirements, and the products invested in "water-lubricated air compressors" have also been highly recognized by the market.
Shanghai granklin group is a professional design, research and development, production, sales and service of screw compressors, and has a global procurement, sales and technical support network. Because it is committed to providing customers with new energy-saving products with excellent cost performance, it has a professional and detailed compressor air source system solutions.
The reasons why the air compressor does not pump air are as follows: it has good environmental adaptability, and the operating cost is economical and the energy-saving effect is excellent. 1. The loose pressure valve of the air compressor is stuck, and the valve plate is deformed or broken. 2. Excessive carbon deposits at the inlet and exhaust ports. 3. No intake valve
Screw air compressor procurement how to choose a good manufacturer? General equipment air compressor industry manufacturers, agents face the danger of being eliminated at any time. In this case, air compressor enterprises strive for perfection on the road of R & D and production, and constantly improve product quality. Water lubricated air compressor manufacturers, Shanghai granklin (group) co., ltd. is doing better and better in the production of oil-free screw air compressors, focusing on product quality and after-sales companies, allowing users to purchase with confidence.
View detailsWater-lubricated oil-free air compressor company direct sales of the whole machine: the water-lubricated compressor is produced for oil-free, and the whole machine uses stainless steel components and water as lubricant, so as to eliminate gas oil and mechanical work impurities from the source. To better products, better service dedicated to the user is granklin do oil-free air compressor core values.
