water ring vacuum pump is a liquid ring vacuum pump is one of the most common. Liquid ring vacuum pump is installed in the pump housing rotor blades have more eccentric. Thrown when it rotates, the fluid and the pump shell liquid ring pump casing concentric with the stated, formation volume displacement pump and liquid ring of rotor blade rotation cycle. When the working fluid is water, the water ring pump.
water ring vacuum pump, the principle of
water ring vacuum pump impeller, pump body, exhaust disk, water absorption in the form of water ring pump body wall, intake and exhaust, auxiliary exhaust valve, etc. Be eccentric impeller is installed in the pump body, when the impeller rotates, pump body of water into the water ring water pump impeller left around, due to the effect of centrifugal force, the water formed a similar to the pump cavity shape such as the thickness of the closed water ring. Water ring coincided with the impeller wheel tangent area on the surface of the inside surface of the lower water ring coincided with the top blade contact ( In fact, the leaves in the water ring there a certain insertion depth) 。 At this point, the impeller wheel, water ring formed between a crescent-shaped space, this space is divided into impeller and blade is equal to the number of a number of small cavity.
if the upper part of the impeller 0 ° as starting point, and then in front of the rotating impeller, 180 °, the small cavity volume gradually changed from small to big, the pressure drops, and with the suction mouth of the suction or discharge tray is same. When the pressure inside the small cavity space is less than the pressure of the pump container, according to the principle of balance of gas pressure, the gas is pumped continues to be draw in small cavity, is in the process of suction. When inspiratory finished with inspiratory mouth isolation, small cavity volume decreases, the pressure increasing, is in the process of compression. When it comes to an exhaust pressure of compressed gas in advance, forward from the auxiliary exhaust valve exhaust. With vent of small cavity volume decreases, and further the pressure rise further, when the pressure is greater than the exhaust pressure of the gas, the compressed gas discharge from the vent, in the process of the continuous operation of the water pump, continuously carrying on the suction, compression, exhaust process, so as to achieve the purpose of continuous extraction.
water ring vacuum pump cavitation phenomenon for prevention and elimination method of
( 1) Lower the temperature of the water
( 2) Improve the accuracy of model selection, make the vacuum pump running in safety area
( 3) Install cavitation protection tube
( 4) With air ejector
( 5) Using lower saturated vapor liquid as working liquid
( 6) impeller, the disc with strong ability to prevent cavitation materials such as
several common methods of water ring vacuum pump maintenance.
1。 In order to avoid the impeller, pump body or the main impeller wear, into the pump chamber with gas and work flow of dust particles can pass a rinse mouth rinse at the bottom of the pump.
2. If you use hard water working liquid, must first to soften hard water, or use solution cleaning pump in a certain time.
3, machine normal working temperature is higher than ambient temperature of 15 ° ~ 20 ° C, C does not allow more than 55 ° ~ 60 ° C, C come on 1 - bearing normal working 2 times a year, clean at least once a year, bearing and lubricating oil to replace all of them.
4, mechanical seal using leakage phenomenon, should monitor the movement of the mechanical seal, the static ring is damaged, or seal is aging, if appear afore-mentioned case, you need to change the new parts.
well, water ring vacuum pump cavitation of common failures to understand, if you want to understand the problem of the roots vacuum pump can not used alone can view the related articles.
However, with the increased prevalence of water pump, it has become far more affordable.
