COMMOM PROBLEMS OF SCREW AIR COMPRESSOR-PART 1

	CAUSES	REMEDIES
Failed starter (The light-emitting often turns on)	1. Contactor is burnt 2. Incorrect or lacking phase 3. Loose connection of cable or small contact surface. 4. The supply voltage is too lo 5. Motor does not work 6. The main structure does not work	1. Check electrical lines for maintenance or replacement 2. Check electrical lines for maintenance or replacement 3. Check electrical lines for maintenance or replacement 4. Check electrical lines for maintenance or replacement 5.Check power lines for maintenance or replacement 6. Turn the main device on, if it does not spin , contact the company or the seller.
The inlet pressure is lower than the outlet pressure	1. The user’s consumption is greater than the amount of supplied air< 2. Clogged air filter 3. Intake valve cannot completely open 4. Pressure function is wrong or parameters are set too high 5. The minimum pressure valve does not work 6. Oil and air separator is clogged	1. a, Air consumption reduce b, Check if the air is leaking on the pipe 2. Clean or replace air filters 3. Check the operation of the intake valve 4. Repair or replace pressure pipe unless reset 5. Check or repair the minimum pressure valve 6. Check and replace oil and air separation equipment
The intaken air pressure is higher than the unload pressure setting	1. The transport pipe pressure is not working properly or the parameter is highly set 2. The unload part does not work 3. Air leaked on the pipe	1. Repair or replace pressure lines, or start and reset the parameters 2. Check the part that does not load normally 3. Check and clean leaked pipes</span
Pressure system is too high (higher than the pressure in the tank)	1. The transport pipe pressure is not working properly or the parameter is too high 2. The unload part does not work 3. Air leaked on the pipe. 4. Too old and damaged gaskets 5. Oil pipe system is leaked 6. Poor quality and bubbily oil	1. Check if the unload part is working properly 2. Check pressure pipe 3. Check if the control pipe is leaking 4. Replace oil-gas separator 5. Check / repair theminimum pressure valve
High discharge temperature	1. Lack of lubricating oil 2. The ambient temperature is too high 3. The cooler on the side is blocked 4. Clogged oil filter 5. Temperature control valve work 6. The type of lubricant is not correct 7. Cooling fan does not work 8. Broken temperature sensor	1. Check the oil level in oil case 2.Improve the ventilation system and reduce room temperature. 3. Clean the cooler 4. Replace oil filter 5. Check whether oi is cooled or not, it not repair and replacement the temperature control valve. 6. Check oil style and replace 7. Repair or replace cooling fan or motor 8. Replace temperature sensor
The outlet air temperature is lower than parameter .	1. The ambient temperature is too low 2. The temperature control valve doen not working 3. Incorrect thermometer	1.Reduce the temperature around cooler 2. Repair or repair temperature control valve 3.Check and replace the temperature gauge or sensor
the over heated oil, Short oil transporting cycle	1.Excessive oil, the oil level in the oil case is too high 2. Oil returns filtering or controling line makingit clogged 3. Gasket of separator is broken 4. Gasket is too old and broken 5. Leakage in oil system 6. Oil is poor quality	1.Check oil level, take excessive oil out 2. Clean components and oil pipes, replace if nescessary. 3. Check separator parts and repace if nescessary. 4. Replace gasket 5.Check the pipes and clean the leaking position. 6. Replace new oil with recommended requirement
Oil flows from upper air filter and coagated.	1. Unload orload in very short time 2.Minimun pressure valve is leaked 3.Air in contactor is insufficient	1.a, Repair intake valve b, Check the closing time of relay and other power lines 2.Repair minimum valveand replace if nesscessary 3. Check shutdown valve
Frequently switches between load and unload	1.The pipes are leaked 2.The pressure parameter is lowly set 3. Unbalanced air consumption.	1. Check the possibly leaking position 2. Reset new parameter 3.Improve storage capacity of tank, add pressure valve if nescessary.
