This article introduces the advantages and disadvantages of the diesel driven portable screw air compressor
In the transmission system of an air compressor, it can be generally divided into direct transmission and belt transmission. For a long time, which of the two transmission methods is better has been one of the focus of debate in the industry. The direct drive of the screw air compressor means that the motor main shaft drives the rotor through the coupling and the gearbox, which is actually not a direct drive in the true sense.
The screw air compressor adopts a pre-packaged screw air compressor with only a single power connection and compressed air connection, and a built-in cooling system, which greatly simplifies the installation work.
Variable Speed electric driven screw air compressor SPM35Y is mainly used in the field of aerodynamics to drive various pneumatic tools.
The screw machine is composed of a feeding system and a locking system. The feeding part is also called a screw arranging machine. The screw feeding machine is a relatively simple way of arranging screws in a row to improve work efficiency. Equipment, widely used in the electronics industry.
The screw machine is a small machine that automatically locks screws. Its action structure can generally be divided into two parts: a feeding part and an electric batch part. The feeding part is responsible for screening and providing screws, and the electric batching part is responsible for taking and locking screws. The generation of the machine not only improves the work efficiency but also reduces the manual work intensity.
Screw air compressor is an oil-injected single-stage twin-screw compressor, divided into single-screw type and twin-screw type. It adopts pulley transmission to drive the main engine to rotate for air compression. The compressed air in the main engine is cooled by oil injection, and the main engine is discharged. The mixed gas of air and oil is separated by two stages of coarse and fine separation, and the oil in the compressed air is separated, and then clean compressed air is obtained.
Compared with the piston compressor, the screw air compressor has a much lower probability of failure, but if it is improperly used and maintained, its advantages are difficult to take advantage of.
The working process of the twin-screw compressor: the motor drives the main rotor through the coupling, speed-increasing gear or belt. Because the two rotors mesh with each other, the main rotor directly drives the auxiliary rotor to rotate together. Under the action of relative negative pressure, air is sucked in. When the tooth crest and the tooth groove work together, the gas is transported and compressed. When the rotor meshing surface turns to communicate with the exhaust port of the casing, the compressed gas begins to be discharged.
The main performance parameters of screw air compressors are power, volumetric flow, suction pressure, outlet temperature, discharge pressure and speed. In the design of screw air compressors, a pair of intermeshing rotors is a very important parameter.
