screw air compressor operating procedures:
1. operators must be familiar with the structure, performance, working principle, operating procedures and precautions of the air compressor.
2. operators must undergo technical training and safety training, and after passing the examination, they shall take up their posts with certificates and shall not operate without certificates.
Check before 3. startup:
1. Check the capacity of the lubricating oil in the oil-gas separator. After normal operation, the oil level in the oil level gauge is best above the upper limit and the lower limit.
2. Check whether the air supply pipeline is dredged, and whether all bolts and joints are fastened.
3. Check whether the various instrument instructions on the low-voltage power distribution cabinet are correct, whether the electrical wiring is intact, and whether the grounding wire meets the standard.
4. During the test run, about 0.5 liters of lubricating oil should be added from the air inlet, and turned several times or jog by hand to prevent oil loss and burning in the compressor during startup. Special attention should be paid not to let foreign matters fall into the body to avoid damage to the compressor.
5. Before starting, the compressor exhaust valve should be opened, the manual drain valve should be closed, and the operator should be in a safe position.
4. operating procedures:
1. Preparation before starting: check the oil level in the oil and gas separator, slightly open the drain valve below the oil and gas separator to eliminate the possible condensed water in it, tighten the valve after confirming that there is no condensed water, and open the valve at the air supply port of the compressor.
2. Turn on: Turn on the power switch, turn on the power supply, and observe whether there is abnormal display on the operation panel and whether the phase sequence is correct. If there is abnormal display, the power should be cut off immediately. The machine can be put into use only after fault treatment. The machine has reverse phase protection and the motor is strictly prohibited from reversing.
3. Start: press the "start" (ON) key on the control panel, and the compressor starts to run according to the set mode. At this time, observe whether the various parameters on the display panel are normal (the pressure does not exceed 0.85MPa, and the exhaust temperature does not exceed 105 ℃), whether there is abnormal sound, and whether there is oil leakage. If so, stop the machine immediately for inspection. When starting up, turn on the host first, and then turn on the slave machine after about 1 minute.
4, stop: press the "stop" (OFF) key on the control panel, the compressor will stop after a period of time, and it is normal not to stop immediately. When the machine is stopped, the slave machine should be stopped and the main machine should be stopped.
5, if the air compressor has a special abnormal situation, you can press the emergency stop button, if you need to restart after 2 minutes.
6. It is strictly forbidden to start the air compressor with load, otherwise the electrical components will be damaged due to excessive starting current.
7. When the air compressor is not in use, the power supply should be cut off and the air supply valve of the compressor should be closed. Discharge the accumulated water in the cooler, oil-water separator, exhaust pipe and air bag 8. When shutting down for maintenance, the knife switch of the power cabinet must be opened, listed and grounded.
Inspection and precautions during 5. operation:
1. Check whether the indications of various electrical instruments are normal.
2. Listen to whether there is any change in the working sound of each part of the machine.
3. Check that the temperature of each part does not exceed the specified value.
4. Check whether the lubricating oil level is normal, and it is forbidden to wipe the rotating parts during operation.
5. When replacing the oil and gas separator, pay attention to the discharge of static electricity, and connect the inner metal net with the shell of the oil drum to prevent the explosion caused by the accumulation of static electricity. At the same time, it is necessary to prevent unclean items from falling into the oil drum to avoid affecting the operation of the compressor.
6. When the compressor exceeds the set time due to no-load operation, it will automatically stop. At this time, inspection or maintenance work is absolutely not allowed, because the compressor will resume operation at any time. For the unit with a separate fan, the operation stop of the fan is automatically controlled, and the fan must not be contacted to avoid personal injury. The mechanical inspection must first cut off the power supply.
In the past, oil-free air compressors could only be produced abroad. The price is a permanent pain in the hearts of the Chinese people. It often costs a lot to purchase a good screw air compressor. Granklin Air Compressor Production Plant, after its establishment in Shanghai, China, mainly produces water-lubricated oil-free screw air compressors, allowing people to have their own oil-free air compressor heads.
Oil-free and water-lubricated screw air compressor is a common model in the oil-free machine family. It uses pure water for lubrication, so the compressed air has high oil-free and water-free purity. Oil-free water lubrication screw air compressor in recent years in the market sales are very hot, price
1. Check whether the fuse is burned and blown, causing the circuit to fail and cannot be powered on. 2. Motor failure. The insulation layer is aged or the temperature is too high, the insulation layer is melted, so that the insulation effect is insufficient and leakage occurs. 3. The motor is locked and overcurrent. Not enough lubricant,
For oil-free "oil-free air compressors", you can consult "Shanghai Granklin Group". We are an enterprise specializing in the production of "water-lubricated air compressors". Years of deep cultivation in the field of "oil-free air compressors" have enabled us to accumulate a lot of experience. The main product "water-lubricated oil-free air compressors" is sold overseas and abroad, from food, chemicals, electronics, medicine, etc, all industries have our products at work, a steady stream of compressed gas for enterprise production.
The air compressor keeps working, but the air supply is still insufficient. The air compressor works to stop the gas tank when there is a little pressure. Listen to the external pipes of the air compressor, the air supply pipe of the air compressor on the air tank, and the one-way valve. Safety valve, pressure switch and other joints are leaking sound. Such as row
There must be internal wear and aging during the long-term operation of the screw air compressor. Therefore, it is very important to regularly maintain and replace consumables in time. Most users are not very clear about consumables. The following is a detailed introduction of the consumables of the screw air compressor. What are the screw air compressor consumables we often say?
View detailsGenerally, there are relevant installation manuals for the installation of mechanical equipment. The same is true for silent oil-free air compressors. Whether the environmental quality is good or not, the silent oil-free air compressors need to pay attention to the installation environment and whether it affects the installation effect. need in sufficient light
Intake valve loading principle steps: 1, start, the motor is turned on, the host starts to run, the intake valve hole suction, the check valve is opened, the compressed oil and gas enter the oil and gas tank, and the lubricating oil in the oil and gas tank is sprayed into the host head (After the temperature control valve). The pressure rises and part of the pressure passes
The reputation of "oil-free air compressor" depends on the users who have used it. When a brand reaches a certain user base, most people say that it is easy to use and the gas supply is stable, then this "oil-free air compressor manufacturer" must be a "oil-free air compressor enterprise" with good reputation and excellent product quality ".
Of course, it is good to be oil-free. It is clearly arranged for you from the price. Oil-free is several times the price of oil (not the kind of small piston air compressor). The compressed air produced by the oil air compressor is with a small amount of oil, and it must be filtered, and it is still endless.
