The screw air comperssor needs to be placed in a flat and upwind position, especially in the mining area or construction site. The screw air comperssor should be placed in a place with less dust as much as possible, and the tire must be fixed to prevent movement.
The screw air comperssor needs to be placed in a flat and upwind position, especially in the mining area or construction site. The screw air comperssor should be placed in a place with less dust as much as possible, and the tire must be fixed to prevent movement. The screw rotates in the barrel, and the lubricating oil and compressed gas rub against the screw and the body, so that the working surface of the screw gradually wears: the diameter of the screw is gradually reduced, and the diameter of the inner hole of the body is gradually increased. In this way, the screw and the body with the diameter of the gap, with the gradual wear of the two and a little bit increased. However, since the resistance of the front head and the splitter plate has not changed, this increases the leakage flow when the squeezed gas advances, that is, the flow of gas and lubricating oil from the diameter gap to the intake direction increases. The twisted screw should be considered according to the actual inner diameter of the body, and the outer diameter deviation of the new screw should be manufactured according to the normal clearance with the body.
As the technical threshold of the screw unit is slightly lower, the brand is various, and the competition is also very fierce. Compared with the competition in technical strength, the tendency of price advantage is more obvious. It should be noted that this part of the screw unit products include water-cooled screw units and air-cooled screw units, but does not include screw water-ground source heat pump units. The water-cooled screw system is a traditional air-conditioning system, which is composed of cooling tower, water-cooled screw unit, indoor terminal device (including fan coil and air handler), air pipe system, water pipe system, circulating water pump group, etc. The chilled water is delivered to the end of the inaccessible area through the circulating pump, and then led to each room requiring air conditioning through the air supply duct. The air duct system can be equipped with flow regulating valves, tuyeres and other accessories. Due to the same principle of refrigeration and heating conversion and operation, water is used as refrigerant to transport cold heat to the room, and the construction and equipment and materials cost is very low. Refrigeration and heating can use the same system without additional independent heating facilities, saving initial investment.
