The welcome visits Shandong Hairui Zhonglian Pump Industry Co. , ltd. Website, the centrifugal pump that my company is a major produces manufacturer. When you need centrifugal pump type selecting, we will provide the before-sales service such as price of centrifugal pump model, centrifugal pump, in order to offer your referenced alternative. This product information is the knowledge that during working about centrifugal pump, safeguards:
1. is lubricant
Centrifugal pump is in moving process, as a result of the medium that is carried, water and other material change enters the likelihood inside gasoline tank, those who affect pump is normal move, accordingly, want to often check the quality of centrifugal pump lubricant and oil level. Check the quality of lubricant, observation of usable naked eye and fixed sampling are analysed. The oil of lube is measured, can see from oil level mark.
Oil change answers after new pump runs a week, the pump of bearing was changed to also answer when overhaul oil change. Because new bearing and axis move,run when closing the eyewinker enters oil inside, must oil change. Every quarter changes oil after. Uses grease adds up to lube, want to accord with quality requirement.
2. vibration
Pump is moving in, because spare parts quality and overhaul quality are bad, operate undeserved or conduit is oscillatory the reason such as the influence, often can produce vibration. If vibration allows a value more than, should jockey the overhaul, lest make,the machine is killed by damage.
3. bearing temperature rise
Pump is in moving process, if bearing temperature rise is very sharp, temperature of the bearing after temperature rise is steady is exorbitant, explain bearing is being made or installation quality respect has a problem; Or bearing lube quality, amount or lubricant means do not accord with a requirement. If be handled not in time, bearing has burned-out risk. Centrifugal pumpBearing temperature allows a value to be: ℃ of sliding bearing <65; ℃ of scroll bearing <70. Should allowing a value is the limit that points to temperature of the bearing after running period of time. Change the bearing on newly, moving initial stage, what bearing temperature can rise is taller, after moving period of time, temperature can drop a few, stable in some numerical value.
The moving function of 4. centrifugal pump
Pump is in moving process, if liquid origin is invariant, of the valve on cop of imports and exports degree did not change, and discharge or pressure of imports and exports changed, inside demonstrative pump or there is trouble inside conduit. Want to prove a cause quickly, eliminate in time. Otherwise, will cause undesirable consequence.
When ① conduit centrifugal pump is being started, to avoid electromotor overload, answer to close exit valve, open slowly again after pump is started. Such, when can avoiding electric machinery to start, the high-power photograph overlay of the load that start and need of place of the pump when exporting valve a standard-sized sheet, and cause electric machinery overload.
② is full of a liquid in pump antrum only (avoid seal ring, axis to seal with) of mechanical and sealed dry attrition, when centrifugal pump is exporting valve to shut, those who allow short time move, unless the finite liquid inside pump antrum, rotating below the action of impeller, temperature rise is very sharp and outside bringing a few bad influences to pump, without what undesirable to electric machinery action, at this moment the negative charge of electric machinery is smaller.
③ moves in, can export valve to leave to spend and get the random inside limits of centrifugal pump function through adjusting a group of discharge and lift, nevertheless, when pump is designing operating mode dot to move, its efficiency is taller; Leave a design operating mode speck is more remote, efficiency is lower.
Thank you to be mixed to the visit of above content very much read! This information is the introduction that during working about centrifugal pump, safeguards, 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 still produces fire pump, welcome you at any time seek advice.
