Air compressor filter introduction

Air Compressor Filters come in a preconfigured configuration that requires only a single power connection and compressed air connections and a built-in cooling system, simplifying installation. Air compressor filters with its high efficiency, high efficiency, maintenance-free, highly reliable, and other advantages consistent for all walks of life to provide high-quality compressed air. Screw compressor components in air compressor filters are manufactured in-house using the latest CNC grinding machines, combined with on-line laser technology to ensure manufacturing tolerances are extremely accurate. Its reliability and performance ensure compressor operating costs have been extremely low over the life of the compressor. Adjustable compressors, integral compressors and desiccant series are all new products in the range of compressors.

Air compressor filter principle

(1) suction process: the motor-driven rotor, the main, from the rotor's trough space is transferred to the intake end wall opening

Compression principle, the space, the outside air is full of which, when the rotor inlet side of the shell turned away from the inlet, the air between the trough is enclosed in the main, from the rotor and the chassis, Complete the inspiratory process.

(2) compression process: At the end of inhalation, the main, from the rotor tooth peak and the enclosure formed by the enclosed volume decreases with the rotor angle changes, and according to the spiral movement, this is the "compression process."

(3) compressed gas and fuel injection process:

In the process of delivery, the volume is continuously reduced, the gas is continuously compressed, the pressure is increased and the temperature is increased. At the same time, the lubrication due to the pressure difference is sprayed into the compression chamber to achieve compression and reduce temperature sealing and lubrication .

(4) exhaust process:

When the closed rotor tooth peak rotation to meet with the exhaust port of the chassis, the compressed air begins to discharge until the tooth peak and tooth groove coincides with the face of the exhaust moved to the exhaust end, when the trough space is zero, that is to complete the row Gas process. At the same time, the main, the other pair of trenches from the rotor have been rotated to the intake end, forming the maximum space, starting the suction process, thereby starting a new compression cycle.


Air compressor filter working pressure

There are many forms of pressure units, mainly introduced here screw compressor air compressor pressure commonly used units;

① work pressure, domestic users often say exhaust pressure. Working pressure refers to the maximum pressure of the air compressor discharge gas;

② common working pressure unit: bar or Mpa, 1 bar = 0.1 Mpa;

③General, the user usually refers to the pressure unit as: Kg (kg), 1 bar = 1 Kg.

Air compressor filter capacity

① volume flow, domestic users often said displacement. Volumetric flow refers to the required discharge pressure, the air compressor discharges the gas volume per unit time, converted to the amount of intake state.

② volume flow unit: m3 / min (cubic / minute) or L / min (liter / min), 1m3 (cubic) = 1000L (liter);

③ general, commonly used flow unit: m3 / min (cubic / minute);

④ volume flow in our country is also known as displacement or nameplate flow.

Air compressor filter air compressor power

① General, air compressor power refers to the matching drive motor or diesel nameplate power;

② power unit: KW (kilowatts) or HP (horse / horsepower), 1KW ≈ 1.333HP.

Air compressor filter use and maintenance of safety precautions

1. Operation, maintenance and service of compressors must be carried out by qualified personnel.

2. The compressor can not be reversed. After the initial start-up or after the electrical system is overhauled, it must first be checked whether the direction of rotation of the motor is consistent with the specified steering before starting the compressor.

3. When removing high-temperature components, the temperature must be cooled to ambient temperature before proceeding.

4. Recommended screw compressor oil. Different grades of lubricating oil are not allowed to mix.

5 without the permission of the manufacturer, do not make any impact on the compressor safety, reliability changes or add any device.

6. Compressor original spare parts are specially designed and manufactured, it is recommended to use genuine spare parts to ensure the reliability and safety of the compressor.

7. It is absolutely not allowed to block the compressor intake during operation.

8. Compressed air must not be used for breathing unless it is indicated for breathing purposes.

9. The compressor can not be operated beyond the specified pressure and temperature.

10. Once the compressor is found to be abnormal, stop the compressor immediately and eliminate the abnormalities promptly.

11. Use the correct tool to service and repair the compressor.

12. After repairs, make sure all safety devices are reinstalled before booting, and the tools have been removed from the compressor.

maintenance 

1. Daily check the oil level, exhaust temperature and exhaust pressure, check for abnormal sound;

2. Turn on the separator blowdown valve to drain condensate before starting every week, check for leaks everywhere, check the safety valve and check the belt wear (visual inspection);

3. Regularly check the intake control valve, the minimum pressure valve, electrical control box cable terminal, safety valve, cooling fan;

4. Regular cleaning, cleaning the cooler, test safety valve reliability;

5. Regular replacement of the oil filter core, oil separator, intake filter element and lubricating oil.

Common troubleshooting

1. The machine does not start: check the main switch and power cord, check the motor;

2 boot machine does not load: adjust the pressure switch setting or replace the pressure switch, check or replace the solenoid valve;

3. The compressor does not unload, relief valve release: adjust the pressure switch setting or replace the pressure switch, check or replace the solenoid valve;

4. Too much fuel consumption: press the recommended oil, reduce the oil level to the normal position, remove the oil return pipe cleaning, replace the oil and gas separator filter;

5. Exhaust pressure is lower than the specified value: reduce gas consumption or increase the compressor, check the system leakage, clean or replace the intake filter core, replace the oil and gas separator filter, check or replace the solenoid valve, check the intake control valve replacement Belt, adjust the pressure switch settings;

6. Compressor high temperature shutdown: to improve the environmental ventilation, cleaning or cleaning the cooler, add oil to the required position, replace the oil filter;

7. Unloading compressor operation, the exhaust pressure is still rising slowly, the relief valve release: check or replace the solenoid valve, intake control valve overhaul, unloading pipe repair;

8. Relief valve relief: repair or replacement of safety valves, overhaul of the minimum pressure valve, replacement of oil and gas separator filter, repair or replace the pressure switch, check the intake control valve or solenoid valve. Intake air filter maintenance Air filter is to filter out the dust of the air components, filtered clean air into the screw rotor compression chamber compression. Screw internal clearance due to only allow within 15u of the particles filtered out. If the air filter plugging damage, a large number of particles larger than 15u into the screw machine cycle, not only greatly shorten the life of the oil filter, oil separator core, but also lead to a large number of particles directly into the bearing cavity, bearing wear and speed up the rotor gap increases, Compression efficiency is reduced, and even the rotor boring dead. Replacement of the oil filter new machine 500 hours after the first run should replace the oil core, with a special wrench anti-rotation oil filter removed, the new filter installed before the best Canadian screw oil, filter seal with both hands screwed back to the oil filter seat, Tighten firmly. It is recommended to replace the new filter every 1500-2000 hours. It is better to change the oil filter at the same time when changing the oil. When the environment is harsh, the replacement period should be shortened. It is forbidden to use the oil filter beyond the expiration date, otherwise the filter will be blocked seriously, the pressure difference will exceed the limit of the bypass valve, the bypass valve will open automatically, a large amount of stolen goods and particles will directly enter the screw host with random oil, causing serious consequences. Diesel screw diesel engine oil filter and diesel filter replacement should follow the diesel engine maintenance requirements, replacement and screw machine oil core similar. Oil fine separator maintenance Replace fine oil separator is screw lubricating oil and compressed air separation of components, under normal operation, fine oil separator life of about 3000 hours, but the quality of oil and air filtration precision Its life expectancy has a huge impact. Visible in harsh environments must shorten the maintenance of air filter replacement cycle, and even consider installing a front air filter. Fine oil separator expiration or before and after the pressure difference over 0.12Mpa must be replaced. Otherwise it will cause motor overload, oil separator broken running oil. Replacement method: remove the oil and gas barrel cover installed on the control connector. Remove the cover of the oil and gas cylinder that is inserted into the oil return pipe in the oil and gas tank and remove the fastening bolt on the cover of the oil and gas tank. Remove the oil and gas barrel cover, remove the oil fine. Remove the asbestos pad and dirt stuck to the top cover. Into the new oil separator, pay attention to the upper and lower asbestos pad must be stapled book, compressed asbestos pad must be neat, otherwise it will cause the pad. Replacing the upper cover, the return pipe and the control tubes as they are and checking for leaks. Maintenance and replacement of screw oil is good or bad on the performance of injection screw machine has a decisive influence, good oil with good oxidation stability, rapid separation, good defoaming, high viscosity, good corrosion resistance, therefore, the user must The pure use of the company dedicated screw oil. After the new machine run-in 500 hours after the first oil replacement, after every 2000 hours of operation to replace the new oil. Oil change the best oil filter at the same time. Use in harsh environment to shorten the replacement cycle. Replacement method: start air compressor operation for 5 minutes, the oil temperature rose to above 50 ℃, oil viscosity decreased. Stop running, when there is 0.1Mpa pressure in the oil and gas barrel, open the bottom of the oil and gas tank release valve, connected to the storage tank. Drain valve should be slowly opened, so as not to bring pressure with temperature lubricants splash wounding dirt. Wait for the lubricant to drop off and close the drain valve. Unscrew the oil filter, the oil in the pipeline at the same time exhausted, put on a new oil filter. Open the fuel filler screw plug, inject new oil, so that the oil level within the oil mark scale, tighten the fuel filler screw plug, check for leakage. Lubricants must be checked frequently in the course of use and found that the oil level line is too low should be timely replenishment of new oil, lubricating oil must also be regularly used in the discharge of condensate, the general situation once a week discharge, in high temperature should be 2-3 days Discharge once. Shut down for more than 4 hours, open the drain valve without pressure in the oil and gas tank, drain the condensate and quickly close the valve when the organic oil flows out. Lubrication oil is strictly prohibited mixed with different brands, avoid prolonged use of lubricants, otherwise the decline in lubricant quality, poor lubricity, lower flash point, easily lead to high temperature shutdown, causing spontaneous combustion of oil.
