Routine maintenance procedures for screw air compressors that you should equip yourself to ensure the best operation of the air compressor.
Do you have experience in maintaining screw air compressors? If you haven't already, don't skip this article. We will introduce you in detail to the maintenance methods of screw air compressors to have a standard screw air compressor maintenance process.
1.Consumables to prepare before maintenance and repair of screw air compressors:
Before proceeding to repair screw air compressors, it is necessary to carefully and fully prepare labor protection equipment and necessary equipment for maintenance and repair. Avoiding the lack of preparation will affect the work progress, especially for customers in remote locations. Basic tools and equipment include:
– Metric Cle of all sizes small->large, quantity 02 sets of good quality
– Cle system of all sizes small -> large, quantity of 02 sets of good type
– Small and large wrenches of each type 02 sets
– Large aperture water pliers up to 2 inches ( 50) for opening large screws
– Small hammers, hammers that have just been firmly rolled, 01 each
- Rubber hammer
– A good set of metric guns 01 set, add a hard handle
– Set of 1 set of good quality guns
– T-shaped set of sizes.
– Pneumatic screw gun 02 pieces (with some accessories for situations to get compressed air)
– Soft plastic pipe to guide when draining oil.
– Plastic and steel tray to store screws and tools when removing screws
– Trolley to push tools and replacement supplies (if any)
– Tool box
– A little diesel oil to clean the machine, or aromatic gasoline.
- Rubber gloves
– Protective clothing, masks, helmets, safety shoes
– Electric meter, current clamp ampere
– Vibration meter for air compressor compressor assembly, and motor.
– Specialized tools for deeper purposes when repairing screw air compressors.
2. Check the machine before servicing and repairing the screw air compressor
It is necessary to check the machine before maintenance, run the machine and record the parameters based on the list of parameters: main engine current, compressor head temperature, oil line temperature before and after the cooler, temperature of the gas leaving the machine. Check the oil level, check for oil leakage in the pipes inside the screw air compressor.
3. The process of repairing screw air compressors
Stop the air compressor and disconnect the power supply. Lock system air valve with air compressor. Press the emergency stop button.
– Pay attention to all the air in the air compressor to escape to avoid the danger of gas dismantling the joints.
– Remove the compressor oil from the oil separator. Rotate the compressor head to drain the oil out of the compressor.
- Clean the inside of the oil separator. Clean the oil return line well to avoid oil loss.
– Change the oil separator filter, change the oil filter, change the air filter, pour oil into the air compressor
- Check hygiene of thermostatic valve
– Cleaning check and overhaul of the intake valve
– Check and clean the cooling rig
– Check the electrical cabinet, check the magnetic starter contacts.
4.Test run after servicing the air compressor.
– Turn on the power to the screw air compressor.
– Open the supply valve to the general compressed air system
– Retry the no-load air compressor, wait for about 2-5 minutes to stabilize
– Running with load monitoring stability
– Load in / out of the air compressor several times
– Monitor the compressor head temperature,
– Monitor current
– Check the overall machine to detect errors, if any
