The core of the rice vacuum packaging machine maintenance is the maintenance of the vacuum pump.
The vacuum pump maintenance is divided into the following 6 points:
1. Replace the exhaust filter If the pump temperature rises significantly, the motor current reaches or exceeds the rated current, and there is soot on the pump exhaust port, check whether the exhaust filter is clogged. If it is blocked, it should be replaced in time. An exhaust pressure gauge can be installed at the pump filler hole to check if the filter is clogged. The exhaust filter can be replaced when the pressure exceeds 0.6 bar (gauge pressure).
2. Replace the vacuum pump oil and oil filter. If the oil is blackened, emulsified or thickened, it should be changed in time. At the same time as the oil change, the oil filter should be replaced. And clean the pump before adding new oil. Cleaning and oil change steps: stop the pump to release the hot oil; screw on the oil drain plug, run for 5-10 seconds, drain the oil; inject cleaning oil (32 ordinary mechanical oil) to the height of the oil window 3/4 Run the vacuum pump for 5-10 minutes; stop the pump and let the oil drain. If the oil is still turbid, it will not meet the requirements. Repeat steps 3 and 4 until the oil is released. Open the oil plug for 5-10 seconds; drain the oil; inject the prescribed new oil. can.
3, vacuum pump oil XD, XQ series vacuum pump should use the vacuum pump oil specified in the composite SH0528-92 standard. The ambient temperature is 0 ° C ~ 10 colloid molding - filling - sealing machine grinding ° C using ISO-VG32 viscosity grade vacuum pump oil. The ISO-VG100 viscosity grade vacuum pump oil (for the original 1# vacuum pump oil) is used at an ambient temperature of 10 °C to 40 °C. When the vacuum pump is running, the oil level must be kept at 1/2 to 3/4 of the height of the oil window. Oil level and oil contamination should be checked frequently (recommended once a week).
4. Clean the suction filter The suction filter should be kept clean to avoid the pumping speed.
5. Storage If the pump is left unused for a long time, the oil should be drained and the pump cleaned, and then the prescribed new oil should be injected in a dry place.
6. If other users need to order repair spare parts, please inform the pump model and machine number can be found on the pump nameplate. For some maintenance and repair work, you need certain expertise, equipment and special tools. Please contact the manufacturer for details. Make sure that there is no oil in the handling of the pump. Do not hit oil pipes, oil filters, etc.
The vacuum packaging machine puts the food into the packaging bag, and extracts the air in the packaging bag to reach a predetermined vacuum degree, and then completes the sealing process. The vacuum forming-filling-sealing machine packaging machine can be installed with a shrink-wrapped filling machine. The function of the machine is: 1. The bag-sealing vacuum packaging machine is equipped with a shrink-wrapped packaging machine. + Sealing; 2, vacuum packaging machine shrink packaging machine directly seals the bag mouth.
