The replacement cycle of air compressor oil mainly depends on the type and quality of the oil, as well as the working environment and running time. Generally speaking, the replacement cycle of air compressor oil can be divided into the following situations:
1. classified by oil type
- mineral oil: Because of its low viscosity, it is easily affected by high temperature, so it needs to be replaced more frequently. It is usually recommended to replace it every 3 to 4 months, or every 2000-3000 hours depending on the operating time.
- semi-synthetic oil: The viscosity is higher than that of mineral oil, which can provide better protection for the air compressor under high pressure and high temperature. It is recommended to replace it every 6 to 8 months, or every 4000-6000 hours depending on the operating time.
- Fully synthetic engine oil: More additives, in the face of high pressure, high temperature and high speed and other complex working environment, can better protect the air compressor parts. It is recommended to replace it every 10 to 11 months, or every 6000-8000 hours depending on the operating time.
2. replacement cycle in special cases
- initial operation of new machine: The newly purchased air compressor must be replaced with new oil after 500 hours of operation, and then replaced according to the normal oil change cycle.
- harsh environment: If the air where the air compressor is located has many impurities, the air contains corrosive substances, the ambient temperature of the compressor room is high, and the air contains a lot of dust, etc., it may be necessary to replace the oil in advance to ensure the normal operation of the air compressor and extend its service life.
Other maintenance suggestions for 3. air compressor
- oil filter: The oil filter also needs to be replaced regularly. It is usually replaced 300-500 hours after the first start, and then every 2000 hours.
- Drive belt: Check the tension of the transmission belt every 2000 hours of operation. If the transmission belt is soft, it needs to be adjusted.
- Air inlet filter: Maintain the air intake filter once a week to clean the dirt in the inner cavity of the air filter housing.
- Filter element: Replace the new filter element every 1500-2000 hours to prevent the harm caused by serious filter blockage.
In summary, the replacement cycle of air compressor oil is the result of a comprehensive consideration of factors such as oil type, quality, working environment and operating time. In actual operation, the appropriate oil should be selected according to the specific situation and replaced in accordance with the specified cycle to ensure the normal operation of the air compressor and extend the service life.
