Advantages of oil-free water lubrication air compressor

Oil and no oil in the air compressor generally refers to the amount of oil content in the gas discharged from the exhaust port of the air compressor. Generally, the oil content of the oil machine is relatively large, and the oil content of the oil-free oil machine is 0.01ppm. Therefore, the oil content is used to distinguish the oil and no oil in the air compressor.

There is also a full oil-free air compressor, it is not the use of oil lubrication, but the use of water lubrication, so the final discharge of the gas does not contain oil called full oil-free air compressor.

oil-free water lubrication air compressor advantages:

1. the current water removal equipment such as refrigerated dryers, non-heat regenerative dryers, and micro-heat regenerative dryers, the water removal function is lost due to the oil in the compressed air. However, the clean oil-free gas compressed by the all-oil-water lubricating air compressor fully protects the water removal equipment and reduces the additional funds brought by the maintenance of the water removal equipment.

2. use of oil air compressor not only need to change lubricating oil but also need to change oil filter regularly. Take a 7.5KW high-quality oil air compressor as an example, it consumes a minimum of 5kg of lubricating oil per month, which will cost 60kg more in one year. At the same time, in order to remove oil from compressed gas, it is necessary to use high-efficiency oil filter and replace the filter core many times, which is also a big expense.

3. because of the high viscosity of the lubricating oil, the current oil removal equipment cannot be completely removed, so that the oil-free air compressor compressed gas does not contain oil.

4. oil-free air compressor is used to provide compressed gas to the outside, the motor load will not be greatly reduced due to the pressure loss caused by oil removal equipment, thus achieving energy saving effect. At present, the high-quality three-stage oil remover will produce a pressure loss of 1 to 1.2kg during use. A 7.5KW air compressor will pay an extra 600W of power loss for every 1kg of pressure increase, and 6 degrees of electricity for every working day (10 hours, for example), this is another long-term intangible expense.

The water lubricated air compressor produced by granklin group does not contain oil. it only needs to replace the air filter element and water filter element regularly according to the manufacturer's requirements and maintain the head of the water lubricated air compressor.
