Vacuum plasma cleaning machine fault processing, CRF cleaning machine manufacturers for you to answer:

Vacuum plasma cleaning machine is actually a surface treatment system, specializing in solving product surface problems to deal with residual impurities, its configuration compatibility is very important, to make its work stable, the operation of the components can not have any error. Especially for the factories with high requirements for UPH, once the failure occurs, it cannot be eliminated in time, and the loss will be very huge. CRF is now based on years of research and development, production and maintenance experience, sorting out the vacuum plasma cleaning machine common fault alarm and treatment methods.

Vacuum plasma cleaning machine

Vacuum plasma cleaning machine
1. Thermal overload protection of vacuum pump of vacuum plasma cleaning machine, please check the fault of circuit and vacuum pump:
(1) In this case, please observe whether the system parameter Settings of the vacuum plasma cleaning machine have changed. If the power is suddenly cut off, the system parameters will return to zero, resulting in this alarming phenomenon of the equipment.
(2) If the system parameters do not change, please confirm whether the thermal relay is automatically protected and press the reset button to start the vacuum generation system. If there is no automatic protection, please check whether the circuit is open or short circuit phenomenon.
(3) Check whether the wire is broken or short circuit.
(4) If there is no above anomaly, please check whether the vacuum pump of the vacuum plasma cleaning machine is normal.
2. The phase sequence of the three-phase power supply of the vacuum plasma cleaning machine is abnormal, please replace the phase sequence protection relay of the phase sequence plasma cleaning machine. If this happens, please replace the phase sequence protection relay.
3. The air supply pressure of the vacuum plasma cleaning machine is too low. Please check whether the gas is turned on or exhausted.
4. The pressure of the secondary air supply of the vacuum plasma cleaning machine is too low. Please check whether the gas is opened or exhausted.
The third and fourth points refer to the alarm of the gas path control system. If this alarm occurs, please check whether the gas is turned on or exhausted. If there is no problem with the gas, please check that the equipment pressure relief meter, gas path solenoid valve and flow meter are normal. Check whether the circuit is broken or short circuit.
5, the vacuum plasma cleaning machine in the vent gas pressure is too low, please check whether the gas is open or gas exhaust, if this happens, please check the vacuum at the bottom of the vacuum cavity vacuum circuit solenoid valve is used to work normally, there is no circuit break or short circuit.
6. The vacuum chamber door of the vacuum plasma cleaning machine is not closed, please close the vacuum chamber door:
(1) When the vacuum chamber door of the vacuum plasma cleaning machine is not closed, such an alarm will appear in the starting device. Please close the vacuum door.
(2) If the vacuum chamber door is closed well and such alarm occurs, please check the sensor and circuit.
7. For mechanical failure of vacuum pump of vacuum plasma cleaning machine, please check the vacuum pumping capacity of vacuum pump and press the reset button for troubleshooting:
(1) the processed products have serious air seepage, the vacuum countdown equipment is very short, in the operation time of the equipment can not be taken out of the vacuum bottom.
(2) The vacuum pump is out of order, so it is necessary to overhaul the vacuum pump.
8. The vacuum degree of the vacuum plasma cleaning machine is high, and the system automatically stops running. Please check the fault and press the reset button to troubleshoot the fault.

(1) the inlet flow setting is too large, can not maintain the vacuum degree.
(2) flow meter failure, unable to control the flow. View lines and flow meters.
(3) vacuum cavity or pipeline leakage, check the sealing of each joint and the sealing of the cavity.
(4) Check the parameter Settings of the system.
9. The vacuum degree of the vacuum plasma cleaning machine is low, the system automatically stops running, please check whether the air supply is normal:
(1) the inlet flow setting is small, can not maintain the vacuum degree.
(2) flow meter failure: flow meter is blocked or damaged.
(3) check whether the decompression instrument and the gas path solenoid valve work normally.
(4) Check the parameter Settings of the system.
10, vacuum plasma cleaning machine vacuum gauge failure alarm, vacuum gauge failure or damage, please check and replace the vacuum gauge, check whether the vacuum gauge control circuit is broken or short circuit.
11, vacuum plasma cleaning machine emergency stop is not reset or has been pressed, open the emergency stop switch to check whether the emergency stop switch is pressed, if there is no such situation, check the emergency stop line.
12, vacuum plasma cleaning machine power failure alarm:
(1) Check whether the power supply equipment is normal and whether the feedback signal is feedback (whether the measuring and detecting end of the multimeter is under pressure).
(2) Check whether the connection of the coaxial cable and the joints is normal (measuring with a multimeter and checking whether the joints are loose).
(3) Check whether the initial position of the capacitor of the matcher is offset. If so, reset it.
(4) Check whether the power supply is set correctly and whether the capacitor of the matcher is normal.
