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 the knowledge that picks pump item about blowdown pumping station:
1. should be satisfied above all taller when the discharge of water supply operating mode and lift requirement, assureBlowdown pumpIn efficient paragraph move. The extraction with big luffing of fountainhead water level water pump stands, appropriate chooses characteristic curve abrupt model water pump; Discharge luffing gives water pump greatly to stand, appropriate chooses the pump with characteristic gently curve.
2. chooses pump to answer as far as possible size is tie-in, allocate agile, choose to be the same as model water pump as far as possible at the same time, each other is reserve.
3. should reduce number of water pump stage as far as possible commonly, choose the big pump with taller efficiency.
4. considers long-dated development, far and near is united in wedlock, because cost of construction of one class pumping station is high, should consider far near future to be united in wedlock more. Common method has:
① obligate position, when water quantity increases, increase new pump;
② near future works with small pump, long-dated change big pump works;
③ changes impeller, the near future installs little vane wheel, long-dated installation large vane wheel works.
Better pump still can be used when amount of long-dated water supply is small.
5. is opposite according to water supply object the diverse demand of water supply dependability, choose reserve a certain quantity ofly pump. Reserve the amount of pump, should pledge according to the sex using water of the user and the user is affirmatory to the requirement of water supply dependability, for instance, industrial water asks with water dependability than the dweller tall, cut off the water supply harm and loss rate are old (like national defence, generate electricity, steely enterprise) , not allow to make commonly cut off the water supply.
Will tell commonly, reserve the setting of pump should satisfy the following.
① does not allow to reduce water supply quantity and the pumping station that do not allow discontinuous water supply, due two reserve aircrew, be like large industrial and mining enterprises.
② allows to reduce water supply amount, assure the pumping station that accident water measures only, or when allowing discontinuous water supply, can set to reserve aircrew.
The pumping station in ③ city water supply and pump of high-level building water supply set to reserve only commonly aircrew.
④ reserves normally pump and bigger pump type are same.
If ⑤ has the water tower of quite large volume in water supply system, also can not set reserve aircrew.
⑥ reserves pump should be in condition of in good condition preparation, can start the work at any time, reserve pump and working barrel are each other to reserve, the relation that works by turns.
6. is chosen as far as possible allow suction vacuum height to be worth surplus of big or indispensible cavitation to be worth small pump, in order to raise the installation height of water pump, reduce pump room to bury deep, reduce cost. The permission of a variety of water pump Hs of suction vacuum height wants roughly identical, if allow Hs of suction vacuum height to differ, when water pump installation differs highly, should take care of a foundation to make the same score neat, low not tall.
Type of 7. water pump must smoke litre of liquid property photograph to suit with place, if give water pumping station to should choose water pump, sewage pumping station should choose ZW as far as possible efficient without jam suck blowdown pump, JYWQ, JPWQ oneself pump of blowdown of dive of automatic agitate divide evenly.
Interior of the size to pump room, configuration, pump room decorates the tectonic type that 8. wants to consider water pump, the cost of pumping station the influence that wait. For example, very low to fountainhead water level, when must building very deep pumping station, choose vertical pump to be able to make pump room area small, reduce cost.
Area condition should be united in wedlock as far as possible when 9. chooses pump, first choice place makes produce into series, finalize the design quite with the product with good performance.
Thank you to be mixed to the visit of above content very much read! This information is aboutBlowdown pumpThe station chooses the introduction of pump item, 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 the pump below fluid, welcome you at any time seek advice.
