Oil-free screw machine and micro-oil screw machine have their own advantages and disadvantages, which is better depends on the specific application scenarios and needs.
oil free screw machine:
advantages:
pure compressed air: Oil-free screw machine does not use lubricating oil in the compression process, so the compressed air produced is completely oil-free, suitable for industries with extremely high air quality requirements, such as food, medicine and semiconductors.
Low maintenance cost: Because there is no lubricating oil system, the maintenance cost of the oil-free screw machine is relatively low, and the maintenance process is relatively simple.
Environmental protection: The oil-free screw machine will not produce oil mist, oil smoke and other pollutants during operation, and is more environmentally friendly.
Disadvantages:
higher acquisition cost: The manufacturing cost of oil-free screw machines is usually higher, so the purchase price will be relatively high.
High requirements for the working environment: the oil-free screw machine has certain requirements for the temperature, humidity and dust of the working environment, and needs to operate in a more ideal environment.
micro oil screw machine:
advantages:
good lubrication effect: The micro-oil screw machine uses a small amount of lubricating oil for lubrication, which can effectively reduce the wear between components and extend the life of the machine.
Wide applicability: The micro-oil screw machine is suitable for various industrial environments, whether it is high temperature, high humidity or dust environment, it can operate stably.
Lower cost: Compared with oil-free screw machines, the manufacturing cost and maintenance cost of micro-oil screw machines are relatively low.
Disadvantages:
compressed air contains trace oil: Although the amount of lubricating oil used in the micro-oil screw machine is very small, the compressed air produced may still contain trace oil, which is not suitable for scenes with extremely high air quality requirements.
Regular replacement of lubricating oil is required: The micro-oil screw machine needs to be replaced regularly to maintain the normal operation of the machine, which increases the complexity of maintenance work.

The carbon deposition cleaning cycle of the screw air compressor is not static, but is affected by many factors, including the use environment of the air compressor, the operating time, the load condition and the maintenance strategy. Therefore, an exact cleaning time interval cannot be given. General
In a factory environment, conventional air pressure usually refers to atmospheric pressure, that is, the pressure exerted by the air in our surrounding environment on the surface of an object per unit area. Generally speaking, the conventional air pressure of the factory is similar to the standard atmospheric pressure, which is defined as 101325 Pa S.
The unit of oil removal from air compressors is usually "PPM" (parts per million) or "mg/m & sup3;" (milligrams per cubic meter), which is used to measure the residual oil content in compressed air. The following are specific instructions: 1. PPM (parts per million) Definition: PP
Small machines are recommended to work continuously for 4 to 8 hours, and piston-type machines also need frequent rest, while industrial-grade oil-free and water-lubricated air compressors and water-lubricated air compressors can run continuously for 24 hours. However, no matter what kind of machine, heat dissipation should be done well and maintenance should be kept up, so that the motor can run for a long time and run steadily.
Air compressor plays a vital role in the enterprise, it mainly solves the problem of power demand for compressed air in the production process. Specifically, the enterprise problems solved by the air compressor can be summarized into the following aspects: 1. Provide power source air pressure
Air compressor faults and treatment methods The high temperature rise of the outlet temperature or exhaust temperature of the air compressor head is a common fault in the operation of the screw air compressor. The screw air compressor often runs at high temperature, which will seriously affect the displacement and operation of the machine.
There are significant differences between dry oil-free screw machine and oil jet machine in many aspects. The following is a detailed analysis of the main differences between the two: 1. working principle Dry oil-free screw machine: Working principle: Through two rotating screws (Main screw and slave screw) compress the gas.
Water-lubricated oil-free air compressor is a special type of air compressor. Its main features and usage can be summarized as follows: 1. working principle Water-lubricated oil-free air compressor uses water as a lubricant when working, replacing the traditional Oil lubrication method. This
The working pressure range of air compressors varies according to their type, specifications and usage scenarios. The following is the information compiled according to different sources and authoritative data: the working pressure range of 1. low-pressure air compressor is usually between 0.4 MPa and 1.2 MPa, and it is also said that low pressure
The cleaning frequency of the screw air compressor cooler should be determined according to the environmental conditions and use conditions to ensure that the air compressor can work at normal temperature, thereby extending the service life of the equipment. Generally speaking, the cleaning cycle of screw air compressor cooler can refer to the following
