How to maintain the vacuum packaging machine for riceThe core of maintenance of rice vacuum packaging machine is vacuum pump maintenance.Vacuum pump maintenance specifically points to the following 6 points:1, replace the exhaust filter If the pump temperature is significantly increased, the motor current reaches or exceeds the rated current, the pump exhaust fumes have occurred, you should check the exhaust filter is blocked, such as clogging, should be replaced. An exhaust pressure gauge can be installed at the pump fill 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 contaminated and black, emulsified or thickened, change the oil in time. When changing oil, replace the oil filter. Clean the pump before adding new oil. Washing and oil changing steps: Stop the pump to release the hot oil; screw on the drain plug and run for 5-10 seconds to drain off the oil; inject the cleaning oil (32th general mechanical oil) to the height of the oil window 3/4 Department; run the vacuum pump for 5-10 minutes; stop the pump and let the oil out. If the oil is released, it is still turbid and cannot meet the requirements. Repeat steps 3 and 4 until the released oil is transparent. Rotate the oil drain plug for 5-10 seconds. Exhaust the oil. Inject the specified new oil. can.3, vacuum pump oil XD, XQ series vacuum pump should use composite vacuum oil specified SH0528-92 standard. Ambient temperature is from 0°C to 10° colloidal-filler-sealer mill °C using ISO-VG32 viscosity vacuum pump oil. Use ISO-VG100 viscosity grade vacuum pump oil (the original 1# vacuum pump oil) when the ambient temperature is between 10°C and 40°C. When the vacuum pump is running, the oil level must be maintained at 1/2 to 3/4 of the height of the oil window. Oil level and oil contamination should be checked regularly (suggested once a week).4, cleaning suction filter suction filter should be kept clean, so as not to reduce the pumping speed.5. Storage If the pump is left unused for a long period of time, the oil should be drained and the pump cleaned. Then the new oil is injected and placed in a dry place.6. If other users need to order maintenance spare parts, please inform the pump's model and machine number can be found on the pump's nameplate. Because some maintenance and repair work requires certain expertise, equipment and special tools, please contact the manufacturer for details. Ensure that there is no oil in the pump. Can not hit the tubing, oil filters and other things.The vacuum packaging machine fills the air inside the packaging bag with the food in the packaging bag and reaches the predetermined vacuum level to complete the sealing process.
