Fuel injection screw air compressor structure principle and common faults

2019-07-27 07:02:26

The oil-injected screw air compressor has become the new mainstream of today's air compressor development, and has unparalleled advantages compared with the piston compressor of the same power. Superior performance and reliability. The vibration is small, the noise is low, the efficiency is high, and there is no wearing parts. The precise cooperation between the main and auxiliary rotors and between the rotor and the outer casing reduces the gas return leakage and improves the efficiency; only the mutual engagement of the rotors and the reciprocating motion of the cylinders The source of vibration and noise are reduced; the unique lubrication method brings many advantages.

Due to the pressure difference generated by itself, the lubricating oil is continuously injected into the compression chamber and the bearing, simplifying the complicated mechanical structure.

The injected lubricating oil can form an oil film between the rotors, and the main rotor can directly drive the auxiliary rotor to rotate without the need for high-precision synchronous gears.

The injected lubricant increases the tightness of the compression.

The lubricating oil absorbs a large amount of heat of compression. Therefore, even if the single-stage compression ratio is as high as 16, the head can be controlled below the carbonation and deterioration temperature of the general lubricating oil, and the rotor and the casing are not generated by the difference in expansion coefficient. friction.

Lubricating oil reduces the noise generated by high frequency compression.

Self-propelled full feed rice combine harvester is applied to rice and wheat which can achieve harvesting, threshing, separating and cleaning all at one time. The compact body design makes it more easily handling and convenient operating, which is especially for small and medium farms.

The cutting platform is equipped at the front of the body, which makes inclining T-shape with the threshing body, is applied to cutting and delivering. Hydraulic controlled lifting of the cutting platform and reel enable the operation more reliable. The threshing and cleaning which includes threshing, separating, cleaning and delivering mechanism etc. is applied to threshing, separating, cleaning and delivering the seeds to the storage box, with the terms in strips and chaffed spread to the ground. The engine is located at under the driver`s seat, which offers the drive forces for the walking, hydraulic system and the working mechanism. Chassis and the walking part are the special self-propelled mechanism, which include front and the rear axle, drive wheels, transmission, and the steering wheels.

The cabin includes the operating mechanism and the instrument system which is for the operating and monitoring the working system.
