Q: Do oil-free air compressors need to be lubricated?
Answer: Oil-free air compressors do not need to be filled with lubricating oil. Oil-free air compressors are commonly used in two series, water-lubricated oil-free air compressors and dry oil-free air compressors.
For example, the water-lubricated oil-free air compressor produced by Shanghai Granklin Group uses water instead of oil for lubrication inside the head of the air compressor. The gas compressed after the head works without oil is naturally oil-free.
The requirements of the fermentation industry for sterile air mainly include the following: Continuously provide a certain flow of compressed air: This is the basic condition to ensure the continuous fermentation process. The flow of compressed air needs to be stable and continuous to ensure the microorganisms in the fermentation tank
The slow gas charging speed of the oil-free air compressor may be caused by the following factors. It is necessary to ensure the efficient operation of the equipment through system investigation and maintenance: 1. The air intake system is blocked The air filter is used as the first barrier for air to enter the compressor. If it is not cleaned or replaced for a long time, it will be
The main function of the screw air compressor cooler is to dissipate the heat generated during the compression process and keep the temperature in the air compressor stable. In the process of air compression, a large amount of heat will be generated. If the heat cannot be dissipated in time, it will cause the air compressor to overheat, thereby reducing
The quality of the air entering the fermenter is critical to the success of the fermentation process. Granklin Group, as a well-known air compressor manufacturer, provides water-lubricated air compressors and oil-free air compressors to meet the demand for high-quality air in the fermentation industry.
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
The power frequency screw air compressor is widely used in the industrial field because of its simple structure, low price, stable operation and convenient maintenance. The following are some common application scenarios of power frequency screw air compressors: 1. manufacturing machinery manufacturing: in machinery
The main difference between air compressor cold dryer and suction dryer is reflected in their use and working principle. First of all, the air compressor cold dryer, the full name of the freeze dryer, the main purpose is to reduce the temperature of the compressed air. Its working principle is to use the principle of refrigeration
There is a certain relationship between the flow and pressure of compressed air, but this relationship is not a simple linear relationship, but is affected by many factors. Definition of the basic relationship between 1. flow and pressure: flow: the volume of the output rate of the compressor system
Compressed air plays a key role in many industries, and its specific application fields and functions are as follows: 1. industrial manufacturing power source and driving tools pneumatic tools: such as pneumatic wrenches, pneumatic screwdrivers, pneumatic grinding machines, etc., driven by compressed air to achieve high
Biopharmaceutical enterprises have strict air quality requirements and need to meet core standards such as cleanliness, temperature and humidity, pressure difference, microbial control, air flow direction, etc. The specific requirements are as follows: 1. cleanliness level requires biopharmaceutical workshops to be divided into different types according to production process and product characteristics.
