Water ring vacuum pump selection and trapped oil, damping problem _

Water ring vacuum pump how to choose

corrosion of water ring vacuum water pump, corrosion resistant materials, such as high vacuum technology in a body, the product has strong corrosion resistance, high ultimate vacuum and large displacement.

for water ring vacuum pump, to ensure its stable running, is for the sake of efficiency and stability, if running near near the ultimate vacuum and exhaust pressure, vacuum pump efficiency is extremely low, and the work is not very stable, easy to produce vibration and noise. And water ring vacuum pump is prone to cavitation phenomenon, cause the damage of the pump body, impeller, etc, can't even work.

after the basic parameters, chosen in the process of the pump:

if the vacuum degree necessary for the pump or the pressure is not high, can choose single pump priority;

if the vacuum degree or high exhaust pressure, single pump often can not meet, or demand under the condition of high vacuum pump still has large swept volume, extraction of stable performance, can choose the double pump;

if the vacuum degree requirements - More than 710 MMHG, can choose gas injector + water ring pump unit as a vacuum device, in order to improve the pumping speed of the equipment under low pressure, avoid water ring vacuum pump cavitation phenomenon at the same time.

in addition if only for vacuum pump, the selection of single pump is better, simple structure, easy maintenance, and under the condition of high vacuum cavitation resistance;

if may also be used as a compressor, choose the double-acting pump is more appropriate. Double-acting pump capacity is big, small volume, can automatically balanced radial force and shaft is not easy to produce fatigue fracture, a longer service life of the pump is.

water ring vacuum pump trapped oil?

water ring vacuum water pump has many excellent characteristics, not oil work, non-polluting characteristics of the environment makes it have extremely extensive application in all walks of life.

water ring vacuum pump in use process, can appear sometimes trapped oil, met how should we solve this problem?

water ring vacuum pump to continuously fuel supply, requires that the overlap coefficient of gear mesh e is greater than 1, which is when a pair of gears mesh has not release, the other a pair of gears mesh has entered into, in this way, will appear at the same time there are two moments of gear meshing, between the two pairs of gear tooth meshing line forms a closed volume, part of the oil is trapped in a closed volume, gear rotates in a row, the closed volume decreases, the two symmetrical on both sides of the mesh point in the node position, closed volume to a minimum, gear and then continue to roll, the closed volume increases gradually, until the volume into the biggest again.

in a closed volume reduced, trapped oil squeeze, pressure rise sharply, the suddenly by a large impact load bearing, lead to pump vibration, the high pressure oil out from all possible leakage cracks, thereby causing loss to the power, oil heating when closed, such as volume increases, because there is no oil, so the formation of partial vacuum, make originally dissolved in the air separation of oil, formed bubbles, after the oil bubble, will cause noise, cavitation and a series of consequences.

the above phenomenon is the trapped oil vacuum pump. This kind of phenomenon of trapped oil very seriously affects the vacuum pump work stability and service life.

in order to solve this kind of phenomenon of trapped oil, the water ring vacuum pump on the pump cover of two trapped oil unloading groove milling. Unloading slot position should make the trapped oil cavity by large hours and can pass the unloading groove and pressure oil cavity are interlinked, and when trapped oil cavity changed from small to big, can pass through another unloading groove and oil absorption cavity are interlinked. The distance between the two unloading groove, need to guarantee at any time can make the oil pressure and oil absorption cavity.

how water ring vacuum pump suspension

there are mainly two damping method:

1, to modify the transmission system

in order to reduce the vibration of motor, drive shaft to the water ring vacuum pump, it is connected to the drive shaft instead of the rigid connection between the elastic. Use elastic sleeve pin coupling, adjust the maximum displacement and Angle compensation, so that the vibration of the motor, transmission shaft can be obtained by elastic coupling compensation, not directly to the water ring vacuum pump

2, strengthening pipeline stiffness

considering the reinforcement of water ring vacuum pump with more difficult, to take in export steel pipe welding 'reinforcement' way. Along the direction of in and out of the water, the water ring vacuum pump export divergent tube and the water valve flange on both ends of the connection between the steel tube, can consult the seller in a few specified thickness, the width of steel plate welding. Increase the stiffness of the steel tube, reduce the deformation and displacement of resistance.
