Gold mine with flow 246 cubic meters, 750 meters of lift, how to choose the MD pump type?

Gold mine with flow 246 cubic meters, 750 meters of lift, how to choose the MD pump type? To two how to choice?

pump technology personnel when received customer consulting found that belongs to the partial operation, flow 246 cubic meters, 750 meters of lift, 8 pump can not meet the requirements of the traffic, suggest to choose 9 water pump at the beginning, 900 kw can meet the requirements. Through communication and engineers, think two MD pump in the same series: the first use MD280 - 100 x8p self-balancing mining wear-resisting pump to meet the flow 246 cubic meters, 750 meters of lift, power of 900 kw; The second choose 7 stage pump, flow 256 cubic meters, 680 meters of lift.

after the solution to the customer, and then do some correction, MD models determine MD280 - pump 100 x8p self-reported pump to ensure flow 250 cubic meters, 700 meters of lift, motor 800 kw.

MD model MD280 - pump 100 x8p self-balancing mining wear-resisting multi-stage pump, rated flow after 280 m/h, 800 m rated head, rated efficiency of 77%, the performance curve as follows:

MDP type self balancing mining wear-resisting multistage pump used to transport particles content is 1 or less. 5%, the particle size 1 or less. 3 mm, the temperature was minus 20 ℃ ~ 80 ℃ medium mine water and other similar wastewater. Is my factory in the D type coal mine with multistage pump, on the basis of improving design of a multistage centrifugal pump wear-resisting, changed the traditional multistage water pump with the design of the balancing device, and accelerate the technology development of high pressure multistage pump, cancelled the multistage pump axial force balancing mechanism, cancelled the balance disc device, is D, DG model of the multistage water pump updated products. Adopted countries recommended by the hydraulic model of high efficiency and energy saving products, with high efficiency, wide range of performance, wear resistance, safe smooth running, low noise, long service life, easy installation and maintenance, etc.

MDP type self balancing mining wear-resisting multistage pump adopts precision casting, reduced the number of parts, components and maintenance disassembling, prolong the life time of the product, large extent to avoid the problem caused by excessive tear open outfit, reduce the maintenance cost; Product the whole machine adopts three dimensional design and nc machining of rotor, strictly to ensure the machining dimension and precision of the parts; Precision positioning, general technical personnel as long as can be done according to the requirements of assembly diagram of assembly sequence and; Completely avoid the old multistage pump must be professional personnel to adjust the location of axial shot size, bringing great convenience to users.
