Analysis and elimination of common fault in nitrogen making machine

Analysis and elimination of common fault in nitrogen making machine

One: fault phenomenon: one of the pagoda is not thoroughly exhaust

Reason: 1. one-way valve leakage 2. back blow valve opening too large

Treatment: 1. replace the check valve or inner sealing ring 2., adjust the opening quantity of the blowback valve two: failure phenomenon: purity decrease.

Reasons: 1. high adsorption pressure (>0.8Mpa) 2. adsorption pressure is too low (<0.6Mpa) 3. adsorption pressure instability 4. gas source oil content 5. intake volume 5. inlet pressure rise too fast 6. outgassing part of gas leakage 7. molecular sieve poisoning

Treatment: 1. reduce intake pressure 2. increase intake pressure 3. intake pressure 3. air intake plus a tank 4. inlet before adding an oil-water separator 5. regulating inlet regulating valve, reducing the intake volume. 6. re insert 7. to replace molecular sieve

Three: failure phenomenon: nitrogen gas machine does not work

Reason: 1. power indicator light is not bright. 2. power plug or socket without electricity. Processing: 1. check whether the fuse is normal (the location of the insurance is at the lower end of the power line and nitrogen receptacle). Use a screwdriver to gently remove one side and pick up the insurance. There are two insurances, one is being replaced by one, and the other is necessary. 2. check whether there is electricity in the plug or socket.

Four: failure phenomenon: the pressure rises slowly.

Reason: 1. inadequacy of intake. The air leakage of the 2. interface is serious. 3. one way valve is leaking or clogging. Processing: 1. increase the intake flow. 2. take off and re insert. 3. check out the one-way valve. Five: fault phenomenon: the pressure of one tower is always zero.

Reason: 1. the computer controller is not working. 2. the valve does not work, the electromagnetic coil may burn out or the valve core will die. 3. may be the stress meter.

Processing: 1. check and debug. 2. touch lightly with iron, check whether the fastening screws of the solenoid valve have magnetic attraction. If the coil is broken, it may be the spool of the spool. Turn off the power supply, open the valve group, remove the valve group, wipe the dust of the spool and the center of the valve with clean soft cloth, and then re install it. If the coil is burned, the coil is replaced. 3. check the replacement pressure gauge.

Common fault and treatment of nitrogen making machine

One: failure phenomenon: one tower exhaust is not complete reason: 1. one-way valve leakage 2. blow valve opens too much treatment:

1. replace the check valve or inner sealing ring 2. to adjust the opening quantity of the blowback valve two: failure phenomenon: the reason for the decrease of Purity:

1. high adsorption pressure is too high (>0.8Mpa), adsorption pressure is too high, 2. adsorption pressure is too low, adsorption pressure is too low (<0.6Mpa), adsorption pressure is too low, 3. adsorption pressure is too low, 4. gas source is over 5. intake of oil, excess of ambassador pressure rises too fast 6. out gas part of gas leakage 7. sub screen poisoning treatment:

1. reduce intake pressure 2. increase intake pressure 3. air inlet plus storage tank 4. inlet before adding oil water separator.
