UV flatbed printer negative pressure meter troubleshooting solution

        The common fault types of uv flatbed printer negative pressure meters are the lack of negative pressure, ± 20 fluctuations in negative pressure meters, negative pressure being too high to adjust, and negative pressure meters being bad. If the machine encounters this problem, it needs to be resolved according to the form of the fault performance to avoid secondary damage.

UV flatbed printer negative pressure meter troubleshooting solution

       1.Vacuum printer negative pressure is missing

       A. The trachea leaks, the solution is to replace the new trachea;

       B. The power supply of the negative pressure pump is abnormal, and the solution is to check whether the circuit is shorted. If this situation exists, it can be repaired in time;

       C. The diaphragm of the negative pressure pump is damaged, the solution is to replace the new negative pressure arm pump;

       D. The solenoid valve is abnormally closed, and the solution is to replace the new solenoid valve;

       E. The ink pressure switch is always on, the solution is to replace the new ink pressure switch;

       F. The ink pressure switch is short-circuited, and the solution should be replaced with a new ink pressure switch;

       The price of the above accessories is between 10-50 yuan. Generally, the faults are broken, and they are directly replaced with new ones.

       2.UV flat printer negative pressure meter fluctuates ± 20

       A. The corresponding power supply box is short-circuited, and the solution is to check the circuit and solve the short-circuited part of the line;

       B. The voltage of the corresponding power supply box is abnormal, check the circuit and solve the short circuit part;

       C. Negative pressure gauge is damaged. Replace the new negative pressure gauge.

       3.The negative pressure of the UV flat printer negative pressure meter is too high to be adjusted

       A. The outlet of the regulating valve is blocked, and the solution can be cleaned;

       B. The speed of the air pump is too high, the solution is to lower the speed of the lower air pump;

       C. The trachea is blocked, the solution can be replaced again.

       4.Vacuum printer negative pressure meter

       A. The circuit has poor contact. The solution is to check the circuit for short circuit, and repair it.

       B. Negative pressure gauge is damaged, the solution is to replace the new negative pressure gauge;

       C. The voltage is too low, the solution is to increase the value of the negative pressure.
