They need to maintenance.After the demolition of all the components to dry, re-assembly and each parts are back to normal. This shows that the pump can not have water to enter,otherwise the vacuum degree and flow rate will substantially decline.And it will show a very weak suction capacity from the appearance .
Vacuum pump manufacturers showed the vacuum degree decline is caused due to the accumulation of dust, but it can not arbitrarily clean with water and liquid water can also not enter into the vacuum pump,otherwise it will influence the life time of vacuum pump.
