Oil injection screw air compressor maintenance steps

1. Check the joint contact and insulation resistance of the electrical part of the air compressor

you can first use an ammeter to detect the current value of each item or use an infrared temperature measuring gun to detect the temperature of the incoming terminal, and make a preliminary judgment to assist in judging whether the wire head is loose.

2. Maintenance of oil filling motor

bearing in the proper lubrication to ensure life, the front and rear end of the motor is equipped with bearings. Normal operation, so grease should be injected regularly, and the type of grease should be selected according to the parameters provided by each manufacturer.

3. Clean the intake valve and filter element

1) Removal of the relief valve: Remove the hose connecting the relief valve and the air filter (note that debris must not enter the air inlet);

2) Remove all other air pipes connected with the relief valve;

3) Remove the solenoid valve coil;

4) Remove the nut assembled between the relief valve and the host and take it down;

5) Move the relief valve to the ground covered with clean paper or related clean laying.

The cleaning method of the air intake filter element is to take out the filter element and gently tap its upper and lower end surfaces, or gently blow off with compressed air to clean the dust and dirt on the filter element. Do not scrub with oil or water. If the filter paper is found to be damaged or heavily clogged with dust and dirt, it must be replaced with a new one.

4, cleaning small pressure valve (also known as pressure maintenance valve)

1) cleaning small pressure valve: according to the method of cleaning relief valve cleaning small pressure valve.

2) Assembly of small pressure valve: The structure of small pressure valve is very simple. It can take out all the internal components by disassembling the valve body cover.

3) Assembly of small pressure valve: Assemble components according to the reverse steps of disassembly. The assembly process will not be described one by one, but attention should be paid to the direction of the U-ring when there is a U-ring inside.

5. Clean the return check valve

1) assembly of return check valve: the valve body has a connection. Take out the spring, steel ball and steel ball seat. There is also a filter screen inside the local one-way valve.

2) Clean the oil return check valve: clean the valve body, spring, steel ball and steel ball seat with cleaning agent. If any, clean them together.

3) Assembly of return check valve: Install the check valve according to the reverse steps of removal.

6. Clean the temperature control valve

cleaning temperature control valve: according to the method of cleaning relief valve cleaning temperature control valve all parts.

7. Clean the cooler

when the oil cooler fouling is more serious, you can remove the oil cooler alone, open the two end covers, with a special cleaning steel brush or other tools to remove the scale.
