In the previous article Xiaobian to introduce to youWhat are the maintenance contents of air compressor？》Today, Xiaobian will introduce you to the steps of air compressor maintenance content?

Air compressor maintenance步骤一：Check the joint contact and insulation resistance of the air compressor。

Use the ammeter to detect the current value of each item or the infrared temperature gun to detect the temperature of the incoming wire terminal for preliminary prediction to help judge whether the cable head is loose。

After the power inspection, swing the wire one by one by hand, feel the tightness of the wire end, and tighten the loose wire end;In addition, it is necessary to test the insulation between the motor, equipment and the ground with a pendulum, and the insulation resistance should be controlled above 500 megohm;Otherwise it should be dried or repaired。

Air compressor maintenance步骤二：Maintenance of motor

Only proper lubrication can ensure the life of the bearing。The front and back ends of the motor are equipped with bearings。Work properly, should be regularly injected grease。The type of grease should be selected according to the parameters provided by each manufacturer。

Air compressor maintenance步骤三：Clean inlet pressure reducing valve and filter element。

Remove the pressure reducing valve: remove the hose connecting the pressure reducing valve and the air filter (be careful not to let foreign matter into the air intake);

Remove the gas pipes of all other components connected to the pressure reducing valve;

Remove solenoid coil;

Remove the nut of the unloading valve and the main engine assembly;

Move the relief valve to a surface covered with clean paper or associated clean paving。

The cleaning method of the intake filter element is: remove the filter element, gently tap its upper and lower end faces, or gently blow with compressed air to clean the dust and dirt on the filter element。Avoid brushing with oil or water。If the filter paper is found to be damaged or clogged with dust and dirt and cannot be cleaned, it must be replaced with a new one。

Air compressor maintenance步骤四：Clean minimum pressure valve (also known as pressure holding valve)。

Cleaning the minimum pressure valve: The method of cleaning the minimum pressure valve is the same as cleaning the pressure reducing valve。

Minimum pressure valve assembly: The structure of the minimum pressure valve is very simple。All internal components can be removed by removing the valve body cover。

Assembly of minimum pressure valves: Assemble components in the opposite steps of disassembly。The assembly process is not a description, but it is important to note that if there is a U-ring inside, pay attention to the direction of the U-ring。

Air compressor保养步骤五：Clean the oil return check valve。

Single return oil valve assembly: the valve body has a connector。Remove the spring, ball and ball holder。There is also a filter in the local check valve。

Clean the return oil check valve: clean the valve body, spring, steel ball and steel ball seat with cleaning agent。If so, wash them together。

Assembly of oil return check valve: Install check valve in the opposite steps of disassembly。

Air compressor maintenance steps六：Clean the temperature control valve。

Clean the temperature control valve: clean all components of the temperature control valve in the same way as cleaning the load reduction valve。

Assembly of the temperature control valve: The surface of the temperature control valve has a cover。Find a suitable nut, screw the cap in, then use the circlip pliers to remove the spring holding the cap in place, then use the pliers to pull the nut you just screwed in, remove the cap and all the internal parts。

Air compressor maintenance steps七：Clean cooler。

When the scale of the oil cooler is serious, you can disassemble the oil cooler, open the end covers on both ends, and remove the scale with a special cleaning steel brush or other tools。When cleaning the medium side of the cooler cannot effectively reduce the temperature, it is necessary to clean the oil side as follows:

Disassemble inlet and outlet pipes;

Inject cleaning solution to soak or circulate with pump (backwash effect is better)；

Rinse with water；

Dry with dry air or remove water with dehydrated oil；

Install inlet pipe and outlet pipe。

Air compressor maintenance steps八：Clean the water vapor separator。

The structure of the water-gas separator is similar to that of an oil tank, with the air inlet designed against the wall and solidified into centrifugal force。Due to the weight of the water, it can effectively separate water from compressed air。

Cleaning of the water and gas separator: remove the cover of the water and gas separator, and then soak it with cleaning agent。

Air compressor maintenance steps九：Confirm all parameters。

After all the above components are cleaned and dried, they will be installed in the air compressor。After installing all components into the air compressor, double check for any omissions and clean up tools and other items used during installation。
