Q: What size of air compressor is needed for 75 cubic meters per hour?
Answer: The gas demand per hour is 75 cubic meters, then 1.25 cubic meters per minute. Granklin water lubricates the 11kw machine of the air compressor, and the gas production per 8kg of conventional pressure can meet the requirement.
The gas production of screw air compressor is generally expressed as m & sup3;/min,L/s,m & sup3;/h, etc.
Oil-free air compressors require lubrication during operation to reduce friction and wear, but they do not use traditional lubricating oils to achieve this. On the contrary, oil-free air compressors use other methods for lubrication, the most common of which is to use water as a lubricant, that is, water
The quality of compressed air, especially its water and oil content, is crucial for many industrial applications. Excessive water and oil content may not only affect the normal operation of the equipment, but also have an adverse effect on product quality. Therefore, choose a model that can produce
The discharge oil content of screw compressors is usually expressed in ppm(parts per million, parts per million). This is a concentration unit used to describe the proportion of oil in the gas discharged from the compressor. The smaller the ppm value, the oil content in the gas
The oil content of compressed air is usually expressed in ppm (parts per million) and milligrams per cubic meter (mg/m & sup3;), both of which are used to measure the degree of oil pollution in the air. ppm is a unit of volume concentration, which refers to the ratio of oil volume to total air volume per million;
The water jet single screw air compressor is an oil-free screw air compressor, which uses water as a lubricant to cool and lubricate the screw and casing. Compared with other types of air compressor, water jet single screw air compressor has the following advantages: high efficiency and energy saving: the use of water jet technology, can
To distinguish whether the air compressor is a variable frequency type, it can be observed and judged from the following aspects: Motor type: The variable frequency air compressor is usually equipped with a variable frequency motor. This motor may be similar in appearance to an ordinary motor, but its internal structure and control methods are
There may be many reasons for the noise of the screw machine, mainly including the following aspects: motor or transmission system failure: motor or transmission system failure, such as bearing damage, gear wear, etc., may cause the screw machine to produce abnormal noise. These faults will affect
The maintenance of air compressor is the key to ensure its efficient, stable and safe operation. Its necessity is reflected in extending the life of equipment, ensuring the continuity of production, reducing operating costs, improving the quality of compressed air, and complying with safety regulations. The following is specific
The air supply pressure used in the machining workshop is usually in the range of 0.5~0.8 MPa(5~8 bar), but the specific pressure value should be determined according to the equipment type, process requirements and safety specifications. The following is a detailed analysis: 1. common equipment air supply pressure demand pneumatic
When purchasing air compressors, companies often face many concerns, such as unstable equipment performance, high energy consumption, high maintenance costs, and substandard environmental standards. In response to these concerns, the water-lubricated screw air compressor produced by Shanghai Granklin Group is characterized by its excellent performance and independence.
