The piston air compressor with many loose parts and poor reliability of the screw air compressor is the trend of the air compressor market today. In the screw air compressor, there are two types of twin screw and single screw. Nowadays, the twin-screw air compressor is commonly used in the market, and the twin-screw is more reasonable and stable in design.
With the screw air compressor, there are four aspects that need to be considered by the user:
Consider screw air compressor speed
The speed is an important parameter of the screw air compressor. The speed is too high, and it is not good. If the speed of the air compressor is too high, the rotor can not withstand, the service life of the air compressor will be greatly reduced; the speed is too low, the displacement and exhaust pressure can not meet the working conditions, and the "running oil" will be serious. .
Consider the operating temperature of the screw air compressor
The working temperature refers to the ambient temperature at which the air compressor is working. If the temperature of the environment is relatively high, the corresponding cooling and cooling measures should be taken. At the same time, the lubricating oil with high viscosity and high flash point should be selected; the ambient temperature is low and will not What is the bad influence. When the air compressor is started at a very low temperature (below 0 °C), it is necessary to pay attention to it. Be careful that the lubricant is condensed inside.
Consider the screw air compressor lubrication method
The lubrication method of screw air compressor can be divided into oil lubrication and oil-free lubrication. The oil-lubricated screw air compressor is commonly used in the market, and the post-treatment equipment can meet almost all kinds of gas demand; The oil-lubricated screw machine is relatively expensive and is suitable for industries with high requirements for compressed air quality, such as medicine and food.
Consider the environment of the screw air compressor
The use environment of the air compressor mainly refers to the site selection of the air compressor station. The air compressor should be placed in a well-ventilated place to avoid direct sunlight and rain; built on hard soil, between the walls, There is a certain distance between the top ends; the relative humidity of the air should be low, and there is less dust and impurities.
