Trouble appearance

Possible reason

countermeasure

Unable startup of compressor

1.Burn out fuse
2.Trouble of startup electrical equipment
3.Badness touch of startup handle
4.Badness touch of circuit
5.Excessively low of voltage
6.Trouble of main electrical machinery
7.Trouble of main engine(strange voice
Or part heat)
8.Lack of phase of power
9.Over loading of fan`s motor

Invite electrician to examine and repair

Compressor automatism stop for high current
(alarm for main motor excessively heat)

1.Excessively low of voltage
2.Excessively high of exhaust pressure
3.Jam of oil ans air separator
4.Trouble of main engine
5.Trouble of circuit

1.Invite electrician
check
2.Check and adjust pressure parameter
3.Change new one
4.Open the engine then check

Exhaust air temperature lower than regular demand

1．Failure of thermostatic valve
2．No-load too long
3．No work of sensor
4. No work of exhaust value

1.Check, wash or change
2. use more compress air or stop machine
3. Check or change
4.Wash or change

Compressor automatism stop for high temperature
(alarm for exhaust temperature excessively heat)

1.Lack of lubricating oil
2.Wrong standard or type of lubricating oil
3.Jam of oil filter
4.Jam of oil cooler or dirty surface
5.Troubleof temperature sensor
6.Get out of control of temperature value
7.Too dust of fan and cooler
8.No working of fan`s motor

1.Add oil
2.Change new oil
3.Change new part
4.Wash
5.Change new one
6.Check ,wash ,change
7.Take apart then wash
8．Check circuit and fan motor

Contain more oil of exhaust air

1.Damage in separator of oil and air
2.Jam in one-way return oil valve
3.Too much lubricating oil

Change new one
Wash one-way valve
Emit partly cooling oil

Exhaust air lower the normal need

1.Jam in air filter
2.Jam in oil and air separator
3.Leakage gas in electromagnetism valve
4.Leak in air-pipe
5.Too light or slipe in belt

1.Clean dust or change new one
2.Change new one
3.Wash or change new one
4.Repair
5.Change new one or tight belt
e

exhaust oil from air filter after close the machine

Damage in spring or of one-way value
or pressurize ring

Change new one

Exhaust air from safety

1.Damage in safety valve
2.Damage in pressure cortrol

1.Change new one or refix
2. refix
