The utility model has been taked six kinds of anti-cavitation measures simultaneously from removing two sides of gas and inhibition vaporization, thereby has eradicated cavitation up hill and dale, the impassable mythology of the cavitation that is through with pump cancer.
1, the CO in the removing condensate water
2, non-condensable gas such as oxygen.
Condensate water enters in the water tank through the water inlet of water tank, because flow velocity is very high, just directly collides on the nexine partition wall, it is low to add jar interior pressure, the unexpected flash distillation pressure release of condensate water is broken condensate water into pieces mist formation, the oxygen, the CO that for the first time condensate water are carried or claim dissolving
2Discharge Deng non-condensable gas, enter the air chamber 2 at the top that is positioned at water tank, outside the air bleeding valve drain tank.Entered between tank body and the nexine partition wall by the condensate water broken into pieces, the screen pack that is positioned under the nexine partition wall (5) through the bottom enters outer partition wall, and rigid impurity is left on the screen pack, treat that sewage draining exit is opened after, the discharge water tank.Along with increasing of the condensate water that flows to (6) between tank body and the nexine partition wall, the horizontal plane of condensate water increases gradually, because the upper edge of nexine partition wall is lower than the upper edge of outer partition wall, water just as waterfall by fall in the air to water tank the jar end, form a very thin cascade, hang in the air, discharge the CO that is dissolved in wherein once more
2, non-condensable gas such as oxygen enters air chamber, at last by outside the air bleeding valve drain tank, eliminated the first hidden danger that produces cavitation erosion, also play deoxygenation and purification water quality simultaneously, get rid of CO
2, reduce acid effect.
2, prevent the generation of whirlpool.
When the water level of water tank reach a certain height, the water-delivery pump starting, under the force action of the gravity F2 of the draft F1 of pump and condensate water, often the axis along water tank produces whirlpool, forces that condensate water is gas-entrained to enter in the pump, formed the necessary condition that produces cavitation erosion, for this reason, we install the whirlpool arrester of a dried mushroom head along the axis of water tank in the bottom of jar, prevent vortex arising, the condensate water of avoiding entering pump is carried gas.
3, adopt multistage vertical pump, eliminate the contribution of the draft of pump the vortex generation.MODEL VERTICAL MULTISTAGE PUMP is stood on the both sides of water tank (1), the water inlet axis normal that makes pump is in the axis of water tank (1), the draft F1 of vertical pump this moment (9) and the gravity F2 quadrature in the water tank, the draft F1 of pump is zero to the contribution that produces whirlpool, the gravity that has only condensate water is the contribution that produces whirlpool, and its value is F2, the water inlet pipe that is far smaller than pump with water tank when coaxial to the eddy effect contribution maximum with joint efforts, F1+F2=F1+F2, this has just reduced the possibility that produces whirlpool widely.
4, the bore of the outlet pipe (8) of water tank (1) is designed to bore, eliminates the negative pressure in the pump inlet water pipe greater than the water inlet pipe (8) of pump (9).The head that is about to water tank really has been added on the water inlet (10) of pump (9), thereby offsets or negative pressure that the partial offset pump is produced when rotating at a high speed, makes that unsettled saturation water is unlikely vaporizes because of suction function, melts thereby suppressed vapour.
5, strengthen the pressure of the water inlet pipe mouth of pipe of pump
Another big contribution of the present utility model is that creationary outlet pipe from vertical pump (10) (12) end is fetched on the water inlet (21) of the water inlet pipe (10) that the part water under high pressure is added to pump (9), the gross pressure of the inlet (21) of pump this moment (9) is P pump discharge pressure+P jar, be far longer than the negative pressure of being produced when pump (9) rotates at a high speed, and certain malleation is added on the unsettled saturation water, becoming shakiness is decided to be stable, suppressed gasification, so back pressure device (19) has been eliminated the cavitation erosion of pump.
6, on the back pressure device, gas eliminator is housed, does not contain any gas, destroy the condition that produces cavitation thereby guarantee to enter in the water of pump near the arrival end of pump.
