Vacuum sealing machine (vacuum packaging machine) maintenance core is the maintenance of vacuum pump, so we call vacuum pump maintenance. 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 oil smoke is generated at the pump exhaust port, the exhaust filter should be checked for blockage. If it is blocked, it should be replaced in time. Available at the pump filler hole
Install exhaust pressure gauge and check if the filter is blocked. 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 blackened, emulsified or thickened, the oil 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 let off the hot oil; screw on the drain plug and run for 5-10 seconds to drain the oil; inject the cleaning oil (No. 32 general mechanical oil) to 3/4 of the height of the oil window; run the vacuum pump 5- 10 minutes; stop pump and drain oil
Off. If the drained oil is still relatively turbid and fails to meet the requirements, repeat steps 3 and 4 until the drained oil is transparent; turn on the drain plug and run for 5-10 seconds; drain the oil; fill in the specified new oil. can.
3.Vacuum pump oil
XD, XQ series vacuum pumps should use the vacuum pump oil specified in the composite SH0528-92 standard. Use ISO- at ambient temperature between 0 ℃ ～ 10 ℃
Vacuum pump oil of VG32 viscosity grade. When the ambient temperature is between 10 ℃ ～ 40 ℃, use ISO-VG100 viscosity grade vacuum pump oil (for original 1 #
Vacuum pump oil).
When the vacuum pump is running, the oil level must be kept at 1/2 ~ 3/4 of the height of the oil window. The oil level and oil contamination should be checked frequently (recommended every
Once a week).
4.Clean the suction filter
The suction filter should be kept clean to prevent the pumping speed from falling.
If the pump is left unused for a long period of time, drain the oil and clean the pump, then fill the specified new oil and place in a dry place.
If you need to order maintenance spare parts, please inform the pump model and machine number can be found on the pump nameplate.
Because some maintenance and repair work requires certain expertise, equipment and special tools, please contact the manufacturer for details.
Ensure that the pump is free of oil during transportation. Do not hit oil pipes, oil filters, etc.
