Oil-free water lubrication screw air compressor generally adopts single screw design. The main feature of this design is the use of pure water as the sealing and lubrication medium, thus ensuring that the output of compressed air is pure and oil-free. Due to the role of water lubrication and sealing, the temperature of this type of air compressor is usually only 40-50°C, achieving constant temperature compression, thereby improving the volumetric efficiency. Compared with the dry oil-free screw air compressor, its efficiency can be increased by 10% to 15%. However, the single screw design also has certain disadvantages, such as a relatively high failure rate. This is mainly due to the speed difference between the screw and the star wheel when the equipment is running, which makes the one-way compression of air easier, but also puts forward higher requirements for the durability of the equipment.
In general, the oil-free water lubrication screw air compressor usually adopts a single screw design. This design has its unique advantages, such as pure oil-free compressed air and high volumetric efficiency, which has significant advantages in some specific application fields. But with the continuous advancement of technology, there may be more innovative designs in the future to meet the needs of different industries.

There is a difference in price between permanent magnet motors and power frequency motors. Generally speaking, the price of permanent magnet motors is higher than that of power frequency motors. The following is a detailed analysis: 1. the reason for the high price of permanent magnet motor Material cost: permanent magnet motor uses silicon copper sheet, copper wire and rotor inlay
When referring to Shanghai domestic oil-free air compressor, it is necessary to mention the water-lubricated air compressor of Shanghai Granklin Group. As a modern enterprise specializing in the design and manufacture of air compressors, Granklin Group is known for its high-quality and high-performance air compressor production.
The export oil content standard of the micro-oil air compressor is the value measured under standard working conditions. Usually, the oil content of the air outlet marked by each brand will not exceed 5ppm (parts per million), and some manufacturers implement the standard below 30ppm. There are also national standards.
The working pressure of compressed air mainly depends on its application and the required power. Generally speaking, the compressed air pressure of the factory air compression station is about 0.6~1.6 Mpa (gauge pressure), which is a relatively suitable range. However, there are also some special cases, for example, when using
The standard of water-free and oil-free compressed air mainly relates to the moisture and oil content in the compressed air. The following are specific standard descriptions of these two aspects: 1. moisture standard: The humidity of compressed air is usually required to be lower than 50%. High humidity may cause
In pharmaceutical enterprises, the microbiological detection of compressed air is the key link to ensure the cleanliness of the pharmaceutical production environment and prevent cross-contamination, and its detection methods, standards, frequency and operation points are as follows: 1. microbiological detection methods Sampling methods Floating bacteria sampling methods: making
What is the role of the screw air compressor cooling (cooling) device in operation? The screw air compressor cooling (cooling) device (cooler) cools, cools and separates the gas discharged from the screw air compressor cylinder (compressed air) Moisture in. Screw
