Regular maintenance and maintenance of Fusheng air compressor
1. Regular maintenance and maintenance of main components
In order to enable the air compressor to operate normally and reliably and ensure the service life of the unit, a detailed maintenance plan must be formulated, manned operations, regular maintenance, and regular inspection and maintenance are required to keep the air compressor unit clean, oil-free, and dirt-free.
The maintenance of main components is carried out with reference to the following table:
project
Content Inspection or replacement cycle (h) hours Remarks
500 1000 2000 2500 4000 Can be extended or shortened depending on the dust content condition
Air filter element to remove surface dust and impurities √
Replace with new filter element √ √
Inlet valve seal Check or replace the seal ring √
Is compressor lubricating oil sufficient √
Replace with new oil √
Oil filter Replace with new parts √first times 500 hours
Oil and gas separator Replace with new parts √
Minimum pressure valve Check the opening pressure √ Clean
Cooler dust removal Remove dust on heat dissipation surface √ Lengthen or shorten depending on working conditions
Safety valve Check whether the action is sensitive √
Drain valve Drain water and dirt √
Transmission belt Adjust the tightness √ Lengthen or shorten according to the degree of wear
Check wear or replace √
Motor Add grease to the motor √ or maintain the motor manual
note:
A. When repairing and replacing components according to the above table, you must make sure: the pressure in the air compressor system has been released, separated from other pressure sources, the switch on the main circuit has been disconnected, and safety signs indicating that closing is not allowed have been made .
B. The replacement time of the compressor cooling lubricant depends on the use environment, humidity, dust and whether there is acid or alkaline gas in the air. Newly purchased air compressors must be replaced with new oil during the first 500 hours of operation, and then replaced every 4000 hours according to the normal oil change cycle. Machines that operate less than 4000 hours a year should be replaced once a year.
C. The oil filter must be replaced during the first 300-500 hours of operation, the second time after 2000 hours of use, and then every 2000 hours as normal.
D. When repairing and replacing the air filter or intake valve, remember to prevent any debris from falling into the main compressor cavity. Close the entrance of the main unit during operation. After the operation is completed, turn the main unit several times in the direction of rotation by hand to make sure that there is no obstruction.
E. Check the tightness of the belt every 2000 hours of operation. If the belt is loose, adjust it until the belt is tensioned; in order to protect the belt, it is necessary to prevent the belt from being scrapped due to oil contamination during the whole process.
F. Every time the oil is changed, the oil filter must be changed at the same time. G. Please use our company's original accessories, otherwise our company will not be responsible for any machine accidents caused by this.
Two, clean the cooler
When the air compressor runs for about 2000 hours, in order to remove dust on the heat dissipation surface, open the cooler purge hole cover on the fan bracket, and blow the cooler with a dust blowing air gun until the dust on the heat dissipation surface is cleaned. If the heat dissipation surface is very dirty and difficult to clean, you can remove the cooler, pour out the oil in the cooler and seal the four inlets and outlets to prevent dirt from entering, and then use compressed air to blow off the dust on both sides or use water Rinse and finally blow dry the water stains on the surface. Put it back in place.
Remember! Do not use iron brushes and other hard objects to scrape off the dirt, so as not to damage the surface of the radiator.
Three, discharge condensate
Moisture in the air may condense in the oil and gas separation tank, especially in humid weather, when the exhaust temperature is lower than the pressure dew point of the air or when the cooling is stopped, more condensate will be precipitated. Excessive moisture in the oil will cause the emulsification of the lubricating oil and affect the safe operation of the machine, such as:
---Causing poor lubrication of the compressor host;
---The oil-gas separation effect becomes worse, and the pressure difference of the oil-gas separator becomes larger;
---Cause rust of machine parts.
Therefore, a schedule for draining condensate should be established based on humidity.
Condensate discharge method
It should be carried out after the machine is shut down, there is no pressure in the oil and gas separation tank, sufficient cooling, and sufficient precipitation of the condensate, such as before starting the machine in the morning.
① Unscrew the front screw plug of the ball valve at the bottom of the oil and gas separation tank.
②Open the ball valve slowly to drain until the oil flows out, then close the ball valve.
③ Screw on the front plug of the ball valve.
Four, safety valve
The safety valve has been set before the whole machine leaves the factory. We do not encourage users to adjust the safety valve privately. If adjustment is really necessary, it should be carried out under the guidance of the local labor safety department or the maintenance personnel of the company, otherwise the company will not be responsible for all the consequences caused by this.
Five, maintenance work recommendations
For general users, we provide some compressor maintenance suggestions for users to refer to and implement.
①Every week:
a. Check the unit for abnormal noise and leakage;
b Check whether the meter reading is correct;
c. Check whether the temperature display is normal.
②Every month:
a. Check whether there is any rust or looseness in the machine. If there is rust, remove the rust and oil or paint, and tighten the looseness;
b. Drain the condensate.
③Every three months:
a. Remove the dust on the outer surface of the cooler and the fan cover and fan blades;
b. Add lubricating oil to the motor bearing;
c. Check whether the hose is aging or broken;
d. Check the electrical components and clean the electric control box.
Six, compressor oil supplement
In the running state, the oil level of the compressor should be kept between the minimum and maximum oil level. More oil will affect the separation effect, and less oil will affect the lubrication and cooling performance of the machine. During the oil change cycle, if the oil level is below the minimum The oil level should be filled with lubricating oil in time by:
①Shut down and wait for the internal pressure to be released (confirm that there is no pressure in the system), pull down the main power switch.
②Open the oil filling port on the oil and gas separation tank and add a proper amount of cooling lubricant.
③Refer to the regular maintenance table for the oil change time after the machine is running normally.
