When we choose a good water ring vacuum pump according to the selection criteria, everything is ready to start up and run. At this time, we should pay attention to some problems. In order to use the pump smoothly in the future, we will introduce the matters needing attention when using the equipment
If there is no vacuum pump between 1 and 13pa.
2. Check whether the oil level of the pump meets the requirements before starting.
3. If the temperature is too high, the pump oil will be oxidized, so before the oil booster pump is opened to the atmosphere, be sure to check the temperature of the pump oil.
4. When the vacuum system is not working, the other parts of the vacuum system are sealed in vacuum except for the mechanical pump.
5. When the oil booster pump starts or stops working, the valve at the inlet of the oil booster pump should be closed first to prevent the pump oil from flowing back into the vacuum chamber.
6. Before starting the water ring vacuum pump, the pressure of the front stage should be within the allowable pressure range. If it has overload protection device, it can be started earlier.
7. If the system is not connected in the future:
Firstly, check whether the turnover rate of the system where the pump is located exceeds the allowable value, and check whether the electric furnace of the pump works normally and whether the cooling of the pump is normal.
(2) if it has been ruled out that the vacuum vessel seal and valve work normally, it may be the problem itself, and it is necessary to communicate with the manufacturer. There may be problems such as deterioration of pump oil, poor cooling, insufficient pump oil or overheating of pump.
Water ring vacuum pump with high negative pressure and small flow rate is suitable for the mine with small pumping volume and high negative pressure. In order to better use in the future, we should make all preparations before starting the machine, and keep in mind the precautions and problems that are easy to occur.
