1, check the liquid ring vacuum pump pipe lines and connections have loose situation. Turn the liquid ring pump by hand to see if the vacuum pump is still flexible. Search Keyword: More Pump Technical Articles The main features of molybdenum rods include high melting point, good thermal conductivity, low thermal expansion performance, good high temperature oxidation resistance, and high temperature strength. Molybdenum can increase steel`s corrosion resistance in the acid-based solutions and liquid metals, thus improve its wear resistance, hardenability, weldability, and heat resistance. As an element which easy to form carbides, molybdenum can effectively avoid oxidation during steel making process, and it can be used alone or mix with other alloy element to achieve the best performance.

2, facing the bearing body with some bearing lubrication oil, observe the oil level is in the oil center line there, according to the situation to make timely replacement or replacement of lubricants.
3, Unscrew the liquid ring vacuum pump head diversion plugs, water diversion or cited pulp.
4, close the outlet valve, outlet pressure gauge and imported vacuum gauge.
5, start the motor, see the motor steering is correct.
6, when the vacuum pump is running, then open the outlet pressure gauge and import vacuum pump, depending on the pressure showed its appropriate, and gradually open the gate valve, while checking the motor load conditions.
7, try to control the liquid ring pump flow and head on the signs indicate the use of the range, to ensure that the vacuum pump in the highest efficiency on the operation, so as to get the maximum energy-saving effect.
8, in the operation of the vacuum pump, the bearing temperature can not exceed the ambient temperature above 35 ℃, the maximum temperature of not more than 80 ℃.
9, if you find the vacuum pump abnormal sound, should immediately stop running check the reason.
10, to stop using the vacuum pump, first close the gate valve, pressure gauge, and then stop the motor.
11, vacuum pump in the first month of work, every 100 hours will have to change the oil, a month later every 500 hours oil change time.
12, often adjust the packing gland, to ensure that the drip filling room normally drip out into the room as appropriate.
13, Check the wear and tear of the shaft sleeve regularly, should replace the new one in time when the wear is bigger.
14, liquid ring vacuum pump in the winter season to use, stop, you need to unscrew the lower part of the pump drain plugs put the media net. Prevent cracking.
15, liquid ring pump long-term need, we should all open the pump, dry the water, the rotating parts and joints coated with grease installed, safekeeping.
