In the normal use of melamine tableware machine, the pressure gauge value display is abnormal, for example, the normal value should be 200, but the pressure gauge shows less than 100, we called Press Drop, how to solve it?
In this case, it is judged as a failure caused by insufficient pressure of the master cylinder of the machine.
Exclusion steps:
Check the appearance of the main cylinder of the machine for oil leakage.
Check whether the vent hole on the back of the machine's main cylinder is locked properly and whether there is oil leakage.
Open the oil tank and check the pressure relief valve and pressure gauge for oil leakage.
If there is no oil leakage in the above accessories, you need to disassemble the pressure relief valve (shown as the icon below) to further check the built-in condition of the pressure relief valve. Under normal circumstances, there will be 2 kinds of failures:
The spool O-ring in the pressure relief valve is damaged and needs to be replaced with a new O-RING
The spool in the pressure relief valve is stuck by some stuff and the spool needs to be removed for cleaning.
