7. Every 20,000 hours or 4 years:

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

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

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.

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. According to the crew's reflection on the recent operation of the machine and the corresponding questions, answer and deal with them;

2. Check whether the air compressor system has water leakage, air leakage and oil leakage, and stop the machine for maintenance if necessary;

3. Check whether the automatic drain of the air compressor, air storage barrel, drying machine and filter is drained normally, and visually see whether the discharged water is in a normal state.

In addition, according to the situation at the time of inspection, the necessary maintenance and repair work will be carried out, and the work sheet will be filled in after each work is completed and the person in charge of the site will sign the order and make the corresponding answers. The above is an introduction to the relevant content of air compressor maintenance.

Correct maintenance and maintenance plays a vital role in the service life and operational reliability of the screw air compressor

Maintenance of air filter: 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 3 m to be filtered out.

If the air filter element is blocked and damaged, a large number of particles greater than 3 m enter the screw machine for circulation, which not only greatly shortens the service life of the oil filter element and the oil-gas separation core, but also causes a large number of particles to directly enter the bearing cavity, which accelerates the bearing wear and increases the rotor clearance, reduces the compression efficiency, and even the rotor is boring and bites, so the air filter element must be replaced every 1500 hours of full load operation of the unit;

Maintenance of oil filter: every 2000 hours of operation of the unit, the oil filter element must be replaced, and it is strictly forbidden to use the oil filter element beyond the time limit, otherwise due to the serious blockage of the filter element, the pressure difference exceeds the bearing limit of the bypass valve, and the bypass valve will be automatically opened, and a large number of stolen goods and particles will directly enter the screw host with the lubricating oil, resulting in the wear of the host.

Maintenance of the oil-gas separation filter element: the oil-oil separator is a component that separates the screw lubricating oil from the compressed air, under normal operation, the service life of the oil-gas separator is about 4000 hours, so the separation core must be replaced every other year or when the pressure difference value of the monitor is alarmed, and if the oil-gas separator is not replaced after the expiration or the pressure difference between the front and rear exceeds it, it will cause the main motor to be overloaded, and the oil-gas separator will be damaged and run oil.

Maintenance of lubricating oil: the quality of lubricating oil has a decisive impact on the performance of the oil-injected screw machine, the service life of Bolaite special coolant is about 3500 hours under normal operation, but the operating exhaust temperature is higher than 95 degrees, the lubricating oil life will be greatly attenuated to 2000 hours, please be sure to use genuine original accessories to ensure the stability of the unit and maximize the operating life; When the oil temperature is above 60, the viscosity will be reduced and will not be hot, and the residual oil of the unit will be drained at the same time. Therefore, if it is cold oil when changing the oil, start the machine and run for 2-3 minutes to heat the oil before replacing it.

Check and adjust each valve, tighten the joints in the electronic control system, and check and set the operation protection parameters of the unit.

Cooling system maintenance: the on-site environment is too dusty, the cooler of the air-cooled unit is easy to block, and the temperature is too high during the current operation, which also leads to the accelerated aging of rubber parts, and the cooler needs to be fully cleaned.

The air compressor needs to check from time to time whether the air compressor has oil leakage, whether there is high temperature, and whether the refrigeration dryer is draining. Whether the filter sponge has a lot of impurities.

The best way to understand: "Screw air compressor operation and maintenance technology Q&A" book published by the Electric Power Press, in the form of technical Q&A, the basic knot, operation and maintenance, working principle and common faults and treatment of screw air compressor are answered in detail, and the size of the air compressor equipment repair steps and technical standards are introduced in detail and supplemented by a variety of typical accidents in practical work, from shallow to deep, properly arranged.

Kaishan Air Compressor Northwest (Xi'an) Service Center 1389289073

The air compressor will have such a problem: the air compressor alarms, and the panel shows that the pressure is too high and stops.

The inspection and maintenance method is as follows: first check whether the minimum pressure valve is normal. When unloading, the minimum pressure valve cannot be opened, resulting in too high internal pressure of the air compressor, and the pressure protection module gets a signal that causes the air compressor to stop.

Check whether the bit is normal, whether the pressure is set too high, whether the pressure sensor is damaged, and whether the oil is blocked.

Replace the three filters, lubricating oil. Clean inside and outside the machine. Check whether the circuit, oil circuit, gas circuit is normal, etc.

Regularly replace the air filter, oil filter, oil content, and oil. And check the circuit, oil circuit, and gas circuit.

Clean the surface dust frequently, replace the lubricating oil regularly, and remove the dust frequently from the air filter, and replace it if necessary.

Piston machine or screw machine?

If you have a piston machine, you can maintain it yourself.

After using the style for a while, blow it clean or replace it.

Remember to put water every day.

Wear and tear use of the belt between the injections.

Screw machine, it is better to find a professional.

The new machine changes the screw oil and oil filter (oil grid) for 500 hours, and then the screw oil, air filter (style), oil filter (oil grid), and oil-oil separator every 3000 hours.

Regularly inspect the use of wearing parts of the machine.

These consumables must be used, otherwise it is easy to malfunction, the host is stuck, high temperature, etc.
