The air compressor repair and maintenance service team, with more than 20 years of after-sales service experience, provides free monthly and quarterly regular door-to-door inspections, quarterly maintenance and cleaning of the main motor and fan motor, replacement of oil filters, cleaning of coolers, inspection of small pressure valves, safety valves, and inspection of sensors. Bolaite air compressor annual maintenance to replace lubricating oil and oil-air separator filters, replace air filter elements, oil filters, safety valve calibration, check elastic couplings, check cooling fans, clean automatic blowdown valves, supplement or replace motor grease. Daily maintenance of air compressor.

Check the oil level, check the air filter element and coolant level, check whether there is leakage in the hose and all pipe joints, check that the consumables have reached the replacement cycle and must be stopped to be replaced, check the exhaust temperature of the main engine, reach or close to 98, and the oil cooler must be cleaned....

Normal air compressor should add special oil, but add ordinary oil can be, if it is the first time to use (no oil leakage, no more than eight hours a day), about a month to put the oil clean, and then add new oil (the machine has oil level holes, round plexiglass, you can see the oil level, normal oil level to half of the round hole), after ensuring that there is no shortage of oil.

Check it out in my homepage and hope it helps.

First of all, you need to clean the floating soil and oil stains on the equipment, and check whether the oil level is in the normal position. Whether each filter is expired or not, replace it in time, and keep a record. Check whether there is a leakage point before starting, check whether there is noise in the running state, whether the oil level is normal, and whether the pressure is normal.

1. The air filter is a part that filters out air dust and dirt, and the filtered clean air enters the screw rotor compression chamber for compression. Because the internal clearance of the screw machine only allows particles within 15u to be filtered out.

2. If the air filter element is blocked and damaged, a large number of particles greater than 15U will enter the screw machine for circulation, which will not only greatly shorten the service life of the oil filter element and oil fine separation core, but also cause a large number of particles to directly enter the bearing cavity, accelerate the bearing wear, increase the rotor clearance, reduce the compression efficiency, and even the rotor will be boring and bitten.

3. The quality of screw oil has a decisive impact on the performance of the oil-injected screw machine, and a good oil has good oxidation stability, rapid separation, good foaming, high viscosity and good anti-corrosion performance, so users must use pure special screw oil.

Daily maintenance has a great impact on the service life and maintenance cost of the air compressor

1) Replace the body bearings and oil seals, and adjust the clearance.

2) Measure the motor insulation, which should be more than 1m.

Air compressor maintenance generally has the first warranty and routine maintenance, the first warranty is 500 hours to need maintenance, the need to replace the wearing parts are air filters and oil filter cores and lubricating fluid, ** how much depends on the SHEMAR brand machine you buy. The number of barrels of oil for a maintenance should also be determined according to the size of your machine, generally a barrel of lubricating fluid below 45kw is enough. Regular maintenance is 2000 hours, and then 4000 hours, hehe.

The regular maintenance is to replace the oil filter, and the oil is divided into air filter and oil. Hope it helps.

1. The dirt in the gas storage tank should be discharged regularly, and the sewage should be discharged at least once every 10 hours of operation, and the sewage valve at the bottom of the gas storage tank should be opened, so that the air compressor can run under pressure for several minutes with pressure and discharge.

2. The lubricating oil should be checked twice a day, and the oil surface must be kept between the two red lines or red circles of the oil viewing mirror.

3. The air filter must be cleaned once a month.

4. Check the reliability of the safety valve and the tension of the V-belt once a month.

5. The compressor oil in the crankcase should be replaced regularly, every 800 hours of operation; The engine oil is special oil for air compressors, 19 in summer and 13 in winter

6. Clean the inlet and exhaust valves regularly, remove the gas valves once a year to remove carbon deposits, maintain the host once a year, check the matching clearance of the main moving parts, and replace them if they are worn too much.

Maintenance of air compressor needs to pay attention to many aspects, therefore, before maintenance, it is necessary to dissipate the air compressor maintenance precautions, as follows:

1. Maintenance consumables should be original, remember not to be greedy. If you use poor quality consumables, there is a possibility of major failures such as the nose getting stuck.

2. When starting the machine, check the position of oil volume, belt tightness, and whether other accessories are normal.

3. If the machine automatically stops due to no-load operation exceeding the set time, inspection or maintenance work is not allowed at this time.

4. The replacement of maintenance consumables should be operated by a professional Lu's industry, otherwise improper operation may lead to machine failure.

5. Don't be greedy and buy low-quality oil, tens of thousands of yuan of machine head can be much more expensive than engine oil.

6. The machine password is generally kept by the first merchant, the purpose is to prevent others from operating indiscriminately and causing the air compressor to malfunction.

To ensure the normal operation and long service life of the unit, good maintenance is key. So, what preparations do we have to make before the maintenance of the air compressor?

1) Cut off the power of the host and hang a sign at the power switch.

2) Close the shut-off valve leading to the gas supply system to prevent the compressed air from flowing back to the part being repaired, and never rely on the check valve to isolate the air supply system.

3) Open the manual venting valve, drain the pressure in the system, and keep the venting valve open.

4) For water-cooled machines, the water supply system must be shut down and the water pipeline pressure must be released.

5) Make sure the compressor unit has cooled down to prevent scalding and burning.

6) Wipe off the oil and water marks on the ground to prevent slipping.

Note: 1) Don't think that the machine is down, just think that it can be overhauled and maintained, and the automatic control system of the machine will start the compressor at any time;

2) Poor maintenance not only affects the normal operation of the unit, but also may affect the safety of the operator;

4) Do not use solvents, such as gasoline or kerosene, to clean air filters or other parts.

In fact, not only good maintenance can extend the service life of the equipment, but also energy saving can also extend the life of the equipment in daily operation. For example, the eight intelligent power-saving systems developed by Zhongke Yujie adopt advanced energy-saving technology, according to the operation characteristics of the equipment, reasonable technology is used to reduce the loss of energy consumption in operation, to achieve the best energy-saving effect, so as to reduce unnecessary equipment loss and extend the life of the equipment.
