When the rocker arm cutting machine is in operation, the stamping head does not move:
Check whether handle button switch wiring head loss, wiring head if no drop, please hands push button switch operation for circuit board whether button indicator lights, if the light switch and circuit board is normal, if not bright lights do not have to rush to judgment circuit board is broken, please continue to check, using the multimeter to check whether there is electricity transformer 30 v or 24 v, if there were no electricity, please continue to check whether there is voltage 380 v transformer, primary electricity, please replace the transformer secondary five.
If there is short circuit in the trimmer positioner, the resistance value of the positioning connector can be checked with the multimeter resistance block to see if it is normal (0-1 value is normal, if it is not within this range, it is abnormal).
If the above points are not abnormal, please continue to check whether the solenoid valve is stuck. If the solenoid valve is stuck, first clean the solenoid valve and then try to install it. After cleaning, it is still useless and the solenoid valve should be replaced.
Pressure instability of rocker arm cutting machine:
First, check whether the fine-tuning positioner is damaged. For example, it is possible to adjust different values of the positioner to cut several times so as to feel whether the pressure is the same each time. If there are different values for many times, the positioner is not sensitive and needs to be replaced. Another problem is that no matter how high the value of the locator is set, the fact that the pressure does not change indicates that the locator is broken and needs to be replaced.
The circuit board contact is not sensitive and the solenoid valve is not sensitive will appear the pressure is not stable situation.
Lower pressure of rocker arm cutting machine:
The trimmer positioner is damaged, no matter how the pressure is adjusted, it needs to be replaced.
The oil pump is damaged, the inside of the oil pump is worn out, it needs to be replaced.
Loosen the oil cylinder or tubing joint and check the oil cylinder for oil leakage. According to the type of rocker arm cutting machine, a rocker arm oil from the lower part of the machine head, the upper side of the casing appeared overflow, this is easy to see. The second type of rocker arm cutting machine needs to open the oil tank cover to check whether the bottom position of the oil cylinder spray. If the leak is confirmed, replace the seal ring in time. It is very rare that the cylinder and cylinder plunger is damaged and leakage occurs, and remember to check whether the tubing connector is loose.
The temperature of hydraulic oil is too high, for example: the power on use for a period of time suddenly becomes smaller, and even there is no pressure. After a few hours of downtime to use the pressure again, followed by a period of time there is no. In this case, it is recommended to replace the hydraulic oil, remember not to buy cheap inferior hydraulic oil.
Rocker arm cutting machine does not start:
Check whether the wire connector of the start button is dropped, whether the start button is damaged, check whether the start button is energized, and measure the resistance value with the multimeter (the pointer of the multimeter is at every turn, indicating normal movement).
If the motor is missing, check whether the three-phase power is normal.
There is a kind of rocker arm cutter is installed thermal relay, check whether the thermal relay protection jump out, if jump out and press down to start again, no use, please replace the thermal relay.
