It has become an inevitable trend to replace a piston type air compressor with many consumable parts and poor reliability with a highly reliable screw type air compressor. According to statistics: Japanese screw compressors accounted for only 27% in 1976 and rose to 85% in 1985. The market share of screw compressors in Western developed countries is 80%, and it maintains its upward momentum. The screw air compressor has the advantages of simple structure, small size, no wearing parts, reliable work, long service life, and simple maintenance.
Screw air compressors have twin screw and single screw. The invention of the single-screw air compressor is more than ten years later than the twin-screw air compressor. The double-screw air compressor is more rational and advanced in design. The twin-screw air compressor overcomes the disadvantages of unbalanced single-screw air compressors and fragile bearings; it has the advantages of long life, low noise, and more energy-saving. After the technology matured in the 1980s, its application range was gradually expanding.
Single-screw air compressor is also called worm air compressor. The meshing pair of single-screw air compressor is composed of a six-head screw and two 11-tooth star wheels. The worm is meshed with two star wheels at the same time. Even if the worm is balanced, the displacement is doubled. The volume of the air compressor is small. Only 9 cubic meters (9m3/min) of air compressor per minute weighs only piston. 1/6. The worm force balance makes the worm air compressor has a series of advantages:
High performance and high efficiency
Air Compressor Equipment - Screw air compressors use high-capacity compression components, which have a low external rotor speed and optimal oil injection, achieving high efficiency and high reliability. Until 2012, the manufacturer's design ensures that the system temperature and compressed air temperature are extremely low. Ensure that all parts have the best cooling effect and maximum service life.
Drive concept
Air Compressor Equipment - Screw Air Compressors Drive compression components with high-efficiency drive systems at the optimum speed for the application. No maintenance is required during normal operation. With the advantages of maintenance-free, highly reliable and high efficiency.
Low maintenance costs
Air Compressor Equipment - Screw Air Compressors The original compressor design saves unnecessary maintenance costs. All components are of long-life design, large inlet filters, oil filters and fine separators ensure optimum compressed air quality. All oil filters and all types of separator components within 22 kW (30 hp) are centrifugal open and close, reducing maintenance time. "Speed ​​up to maintenance points" enables repairs to be completed in minutes, with greatly reduced downtime and maintenance costs.
Built-in intelligent control
To reduce operating costs, precise operational controls are essential. All screw compressors are equipped with intelligent control systems and their control menus are easy to use.
The screw compressor is a volumetric gas compression machine with a working volume for rotary motion. The compression of the gas is achieved by a change in volume, which in turn is achieved by means of a rotary motion of the pair of rotors of the compressor in the housing.
The basic structure of the screw air compressor: in the body of the compressor, a pair of intermeshing spiral rotors are arranged in parallel, and usually the rotor with convex teeth outside the pitch circle is called a male rotor or a male screw. The rotor with concave teeth in the pitch circle is called female rotor or female screw. Generally, the male rotor is connected with the prime mover. The male rotor drives the last pair of bearings on the female rotor to realize axial positioning and withstands the compressor. The axial force. Cylindrical roller bearings at both ends of the rotor enable the rotor to be positioned radially and withstand radial forces in the compressor. At both ends of the compressor body, orifices of a certain shape and size are respectively opened. One is for suction, called air intake; the other is for exhaust, called exhaust.
Intake
Detailed analysis of the working process of the screw air compressor The air intake process: When the rotor rotates, the space between the teeth of the yin and yang rotor turns to the inlet end wall opening, and the space is the largest. At this time, the space between the rotor tooth groove and the air inlet is communicated. When the exhaust gas is completely exhausted when the exhaust gas is exhausted, the tooth groove is in a vacuum state. When it is transferred to the intake port, the outside air is sucked and enters into the tooth groove of the male and female rotors in the axial direction. When the gas fills the entire tooth groove, the inlet side of the rotor turns away from the inlet of the housing and the gas in the tooth groove is closed.
compression
Detailed analysis of the working process of the screw air compressor: the yin and yang rotors are closed at the end of inhalation, and the tip of the yin and yang rotors are closed with the casing. At this time, the gas no longer flows out of the tooth groove. The mating surface gradually moves toward the exhaust end. The space between the meshing surface and the exhaust port is gradually small, and the gas in the tooth groove is increased in compression pressure.
exhaust
A detailed analysis of the working process of the screw air compressor exhaust process: when the meshing end surface of the rotor is turned to communicate with the exhaust port of the housing, the compressed gas starts to discharge until the meshing surface of the tooth tip and the tooth groove moves to the exhaust At the end face, the space between the engaging surface of the yin and yang rotor and the exhaust hole of the housing is 0, which means that the exhausting process is completed. At the same time, the length of the tooth groove between the meshing surface of the rotor and the inlet of the housing reaches the maximum Long, the air intake process again.
