The PU global two: hard wood foaming machine troubleshooting

The automatic cleaning part and the power cut operation part of the ejection part
Normal operation
MC solenoid valve and ball valve is closed on the right, normal operation, press the MC button. MC solenoid valve open, set the time stop, MC automatically shut down, automatically converted to blow.
Such as MC solenoid valve is closed, there is a leak MC, then check the MC solenoid valve is a residue, so that the closure is not strict, clear.
Power outage
Open the MC solenoid valve on the right side of the plug valve, with hand pressing a cleaning body cylinder solenoid valve and the manual button, light press repeatedly, the MC will automatically spray finished using to restore the original normal operation.
Two. A, B pressure gauge operation instructions in the lower part of the main engine
Pump pressure gauge: different feedstock viscosity and flow velocity and pressure along transform, normal, if pressure 5kg, in operation or radio material, if pressure is less than 5kg is the filtration cylinder plug. At that time, remove the filter net, clean, shoot material. If the pressure is greater than 5kg is adjusting hole plug, at this time should be split down the entire hole cleaning or replacement of new products.
Adjustment hole section:
When shooting material, the stability of the pressure gauge, by adjusting the hole to control, such as the A pressure gauge when the injection hole is small, it is to change the larger point of adjustment hole, and the pressure gauge is large, it is to replace a small hole, normal injection, the pressure rise or fall in 0.5KG.
Three. Pressure adjustment
1 air compressor pressure should be maintained at more than 7KG/C square meters.
2 foaming machine total air pressure regulator to 7KG/C square meters.
3 A material, B material barrel pressure control valve, generally as long as less than 2KG/C square meters.
4 material, B barrel of the pipeline pressure is best able to close.
5 cleaning barrel pressure, general control in 2.5KG/C square meters, can not be too large.
Four. Filter tank cleaning and assembly
Barrel switch off below the 1 barrels of raw materials, will let the barrel in the air.
2 raw materials for the pre cleaned filter tank.
3 open the filter lid.
4 remove filter tank cleaning. (a filter cylinder, with cleaning agent and soaked for about 24 hours, to air dry and then into the filtering barrel, B material cylinder MC to clean, to air dry reload filtering barrel).
5.O ring is placed, into the filter tank, then lock the lid.
6 to open the material barrel below the barrel of the total switch.
7 re adding gas.
Five.MC solvent filling
1 to close the air inlet valve into the solvent tank.
2 to open the valve, the pressure to be reduced to zero.
3 open the lid to solvent solvent feeding.
4 O type ring, locking lid feeding.
5 off pressure relief valve.
6 open the intake valve (note MC solvent is not too full).
Six. Maintenance of mixer and mixing head
1 before or after the electrical repair, please confirm whether the steering is normal.
2 each time the disassembly and stirring leaves, all need to be on the axis of the silk thread on the butter, in order to prevent tooth damage.
3 after each infusion, please wash as soon as possible in order to avoid the raw material to solidify on the agitator.
4 when the mixer has difficulty or abnormal sound, it is said that there is a cure phenomenon, should be replaced immediately and remove the raw material in the blender.
5 the method of removing the agitator is following two kinds: the air is blown out of the ashes, and the air is blown away by the air, and the agitator is soaked in the cleaning agent and then washed.
The cause of failure is and the exclusion method:
A: press the button to start the motor pump raw material pump does not move
Main reason
Heat 1, electromagnetic switch, switch off
2, electromagnetic switch coil damage
3, pressure gauge control
Exclusion method
1, press the button to switch back to the heat accumulation
2, replacement.
3, the raw material of the top temperature is required to improve the safety factor
Two: pump rotation but not cycle
Main reason
1, the filter barrel (barrel switch) did not open
2, filter screen block
3, pump internal blockage
Exclusion method
1, open the main switch
2, remove the plug
Three: the pressure gauge without pressure pump does not move.
Main reason
1, sprue feed valve or return valve closed
2, the temperature of the raw material pipe
3, raw material pipe plug
Exclusion method
1, open the ball valve
2, heating or improve the pressure control has the coefficient
3, removal or replacement
Four: raw material temperature can not rise
Main reason
1, temperature control fault
2, the temperature regulator set too low
Exclusion method
1, replacement or repair
2, re setting temperature
Five: unable to perfusion
Main reason
1, the action of the solenoid valve
A air pressure
B cylinder bad, damage
2, filling nozzle blockage
3, look at the B, A pump is open
Exclusion method
1, check the air to make it normal, check the air inlet of the ball valve is open
2, repair or replacement
3, clear
4, open B, A pump
Six: perfusion can not stop
Main reason
1, the conversion of the electromagnetic valve
2, perfusion into the switch side
Exclusion method
1, the action of the solenoid valve
2, check the timer button switch circuit that bad to be replaced
Seven: mixing head mixer can not rotate
Main reason
1, mixed with the head of the accessory installation
2, mixed horse
