A hydraulic motor is an element of a hydraulic machine that converts the hydraulic pressure of a hydraulic system into rotating power. When the motor of the melamine tableware molding machine does not work properly, it will reverse or appear to be unable to rotate. How can troubleshoot and deal with the problem? Case 1, Melamine Tableware Forming machine Not yet Running: The reverse rotation occurs when the motor is started, which is caused by the lack of phase of the power supply. It is necessary to find where the phase loss of the internal and external lines of the machine is. For example, a certain line of the total power supply is poorly connected, resulting in a phase loss of the total power supply. The power supply of the melamine tableware forming machine will also have a phase loss problem, which causes the motor to not work properly. Case 2, Melamine Tableware Molding Running: The reason for the motor reversal is probably due to the lack of phase. The contact on the AC contactor needs to be checked for abnormal contact. If any of the three lines have abnormal contact or poor contact, it can cause the motor phase loss problem. Specific troubleshooting methods: A. First, remove the 3 lines connecting the motor above the contactor (in the figure below of picture) B. Start the motor, the AC contactor will automatically suck in C. Prepare a multimeter and adjust the meter to V-file D. Measure whether the voltages of the three connecting lines are the same: 12, 23, 31. Under normal circumstances, the voltage display of the three lines is the same. If any of these lines show inconsistent voltages, it is a problem of phase loss. As shown in the figure above, there are 3 rows of lines that need to be checked, and there is a corresponding troubleshooting sequence, which can help you troubleshoot and solve specific problems faster: A. The Red area lacks phase, you need to check the main power supply and the external power supply of the machine B. The Yellow area lacks phase, the contact area is damaged, and the contactor needs to be replaced C. The Green area lacks phase, and the overload protector is missing. A new overload protector needs to be replaced The correct inspection sequence should be: A-B-C Tips: SHUNHAO machine using the well-known brand of contactors, qualified parts and easily get the spare parts locally.

Trouble: When the melamine crockery compression machine is pressuring, the mold can not close or the pressure oil gauge is over 200. Why and how to solve this problem? Troubleshooting method 1: Check whether the module is loose Step 1: Turn off the power of the machine and pull out the module Step 2: Re-insert the module and lock the two black lock blocks up and down Step 3: Gently shake the module, to check if it is lock tightly and not moved. Under normal circumstances, if the module is locked, it cannot be moved. Step 4: Restart the power supply, press button of Curing (or any other buttons) to check whether the mold can be properly closed. If the mold can be closed normally, the problem is solved. Troubleshooting method 2: If the module is not loose, then start to check the sensor on the machine stroking board. For example, if starts the button of Curing, the machine pressurizes and the mold closes normally. But Press the button of Finishing agent (means Glazing), the machine pressurizes, and the mold can be closed, but the pressure exceeds 200 abnormally. Then correspondingly find the sensor of Finished agent slow-up on the stroking board, and check whether the corresponding sensor light is on when the machine is pressurized. If it is light-off, it means that the sensor needs to be adjusted upwards. When the machine is pressurized, the corresponding sensor light should be on for the pressure to work properly. After adjusting up, the light is on when machine is pressuring, then the problem is solved.

The oil tank of the melamine tableware moulding machine is on the right side of the machine. There is a meter (dual-meter) on the right side of the oil tank, which can display the amount of oil. Before operating the new machine, it is necessary to inject hydraulic oil to a certain height, and then start up. The oil tank meter in the picture is a dual-meter, the hydraulic oil temperature is displayed on the left, and the scale of the oil quantity is displayed on the right 1. The amount of oil feeding into the new melamine tableware molding machine requires a scale close to 170. Do not exceed this scale. If feeding extra oil, when the machine descends, excess hydraulic oil will be sprayed out through the oil filter, causing unnecessary waste and also contaminating the valve block accessories, etc. 2. After the machine starts normal operation, the oil will drop to 120. 3. Another function of the oil tank meter is to check the temperature of the hydraulic oil. Normally, the temperature of the hydraulic oil is below 50 degrees.
