The welcome visits Shandong Hairui Zhonglian Pump Industry Co. , ltd. Website, the blowdown pump that my company is a major produces manufacturer. When you need blowdown pump type selecting, we will provide the before-sales service such as price of pump of blowdown pump model, blowdown, in order to offer your referenced alternative. This product information is about blowdown pump machinery sealed divulge reason and the knowledge that transform a method:
Pump of phreatic water blowdown basically uses common contact machinery of double end panel is sealed, but in actual project application, often as a result of occurrence breakdown of a lot of reason cannot prevent effectively by the leak of sealed medium, contain solid grain to leave medium, often to carrying especially stop reach easy the technological process pump that manage to find time, sealed dependability is far be inferior to person meaning.
2, the machinery of pump of blowdown of dive of Hairui Zhonglian Pump is transformed sealedly
Because cone machine is sealed and special,agree with the pump that contains solid to hang chaotic content sends equipment, so cone of sealing surface instead sealed. Static annulus material is fill 4 fluorine ethylene, the material that move link is stainless steel, tungsten of cone spray carbonization. Its are main the characteristic is as follows.
1) cone machinery moves annulus sealedly to be one awl annulus, as static annulus wear away, osculatory generatrix length grows, the external diameter of static annulus also increases subsequently.
2) length of sealed interface generatrix is very short (steady movement initial stage is 0.3-0.5mm) , difference in temperature of inside and outside of osculatory end panel is accordingly small, temperature rise is small, lowered rate of stick together tatty. Static annulus is had bigger fight pressure sectional, pressure is out of shape small.
3) gland and the float sex with move annulus to be had certain, can make sealing surface holds good osculatory position from beginning to end, the suspension grain in medium enters sealing surface not easily. Medium is divulged direction becomes proper point of view from mental efforts direction with its, advantageous to reducing leak.
4) buffer fluid pressure is less than by sealed medium pressure, to assure the sealed function of double end panel, the pressure of theoretic requirement buffer fluid must prep above by the pressure 0.1-0.15mpa of sealed medium, contain the medium leak of certain noxiousness in order to prevent. But in actual project, the pressure of buffer fluid is not more than 0.3mpa, be less than by the pressure 0.55mpa of sealed medium, sealed use effect is not accordingly ideal.
5) many solid grain is contained in carrying medium, as a result ofBlowdown pumpIt is an all sorts of craft in storage tank is being discharged in technology unit fluid (include many cooling water) time carry sewage disposal station to undertake depurative handling, contain certain proportional impurity among them kind solid grain, enter extremely easily sealed between generation grinds bead acutenessly to wear away, make sealed early failure. If buffer fluid support system cannot work normally, the pressure of occurrence buffer fluid is less than by the pressure of sealed medium when, solid grain can enter inside between sealed end panel, the probability of its invalidation increases greatly.
6) be in leave often park position, when sewage storage tank medium liquid is smoked send after ending, blowdown pump stops automatically to move, and build up to provide juice when the liquid in storage tank hind, pump automatic switch comes moving condition, because pump is in,leave often park position, make machinery sealed appear periodic do not work firmly surely rub condition, this also is one of main reasons of sealed and frequent invalidation.
7) pump is easy appear manage to find time, because pump is in,leave often park position, when the fluid in storage tank drop when certain level, make blowdown pump appears very easily manage to find time phenomenon, produce acuteness vibration and noise, the generation of this phenomenon is brought about necessarily sealed the working status that appears to be not stabilized, the possibility of sealed invalidation increases greatly.
Integrated above analysis can is informed, machine of average contact of double end panel is sealed because oneself is sealed the characteristic of the limitation of the principle and operating mode condition, make sure below this ambient conditions sealed long periodic safety moves hard. And, below condition of steady working condition, although use double end panel sealed or series connection is sealed basically can eliminate by the leak of sealed medium, but sealed support system is complex, moving expenses soars, and the dependability of support system affects sealed use result directly.
Thank you to be mixed to the visit of above content very much read! This information is about blowdown pump machinery sealed divulge reason and the introduction that transform a method, if you still want to have farther knowledge to this problem, or want to buy this relevant product, contact personnel of my company customer service directly please, my company returns production to suck pump oneself, welcome you at any time seek advice.
