Without jam blowdown pump impeller wears away case study

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 jam about notting have blowdown pump impeller wears away the knowledge of case study:

The influence is not had jam the design parameter that the main factor of service life of blowdown pump impeller is impeller and material. Reducing impeller material to be able to bear or endure below the premise of corrode sex, improve performance of its wear-resisting caustic, optimize the design parameter of impeller, it is to extend the way with impeller more efficient service life.
Without jam tatty of blowdown pump generation is main the reason is opposite of current of grain of high speed solid those who shed a part wear away destroy, it is cavitation and tatty combination are destroyed next. Accordingly, prevention and cure is not had jamBlowdown pumpTatty is essential measure is to try to had been reduced shed current of grain of component surface solid relative speed. Again complementary wear away with be being fought necessarily material is reached character defend coating, criterion the effect is more apparent. Destroy to cavitation, can treat through optimizing hydraulic design to be able to prevent.
So specific how to want to do? Can from the following 4 respects begin:
The appearance that 1. improves impeller is bright and clean degree, in order to reduce vacuole the formation of amiable acupuncture point.
2. is to use the data with fight wear and tear to corrode function good, because the wear and tear of metallic stuff is corroded,be mechanical power cause wear away and the corrodes joint action result of medium. Because this is used,be able to bear or endure already the precautionary measures that the material that corrode fights wear and tear again will be effective, according to integration analysis hind, choose 2Cr13 of martensite stainless steel, classics after quenching, hardness is taller, corrosion resistance is good.
3. is designing a respect, because solid grain has been been opposite,the wear process that sheds the surface is compound wear away, cutting wears away and be out of shape namely wear away to exist at the same time, corrode gross so the conference is bigger. Rate is older, plasticity of material be wearinged away is smaller, total wear extent is bigger, in designing a process consequently, below the circumstance that makes sure discharge, lift is changeless, increased impeller to import a diameter, reduce flow relative speed, improve condition of going from place to place, decrease onflow and add appropriately thick the geometrical dimension of impeller around cover board.
4. defends in facing of corundum of oxygen of annulus of the spray on impeller, wait by agent of epoxy resin, solidify, flexibilizer, thinner and filling mix make mortar, daub is mixed in impeller spiral case apparently. Ground floor and intensity of knot of mother capable person 400 ～ 450kg/cm, 130kg/cm2 of middle-level tensile strength, compressive strength 500kg/cm2, shear strength 300kg/cm. It is complementary agent with corundum, epoxy resin gives priority to the felt material that the agent distributes, and the wearability of corundum is better, so both couple appears piece stick relay strong, be able to bear or endure ability in swimming and it is good to fight silt abrasiveness, and have stronger anti-impact properties.
Thank you to be mixed to the visit of above content very much read! This information is jam about notting haveBlowdown pumpImpeller wears away the introduction of case study, 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.
