WN450 dredging sludge pump for transportation river sand
ZD Dredge Pumps are solitary-stage single suction cantilever horizontal centrifugal pumps with positive aspects of light weight, good wear-resistant,
super dredging performance, ZD dredging pumps impeller passage is extremely vast, It can repeatedly transportation gravels or high plastic clay and not
occurs jam, particularly for dredging sands and damming of the river and seas.
ZD Series Dredge Pumps can be also built-in with the gearbox, that indicate the pump and equipment box share one frequent shaft.
So It doesn’t need to have the pump bearing assembly and frame, In this way, not only conserve space, but also lessen cost and breakdown ratio,
allow the dredge pump give enjoy to optimum performance.
It is a new sort of River Dredging sand Pump researched and manufactured by our organization aiming at the dredging and damming of the river or lakes.
2.Solution functions and overall performance parameters
(1)Composition suitable for dredging ship:
The structure of 200ZD-500ZD type pumps are single-casing, single-stage, one-suction, cantilever
and horizontal. According to the link with the gear box, two buildings can be provided: self-carrying
bracket and pump-box assembly. The lubrication for the bracket isgrease or slender oil.
The structure of 600ZD-1000ZD type pumps are double-casing, one-stage, single suction, cantilever and
horizontal. It has self-carrying bracket. Lubrication is forced slim oil lubricating. The double-casing design
can make certain the liner can function till it is worn out, and if the liner crack, h2o can not enter into the pump.
(two)Simple to Disassembly and Installation, Convenient Routine maintenance:
ZN variety pump adopts front-disassembly structure in favor of effortless disassembly and servicing. Also it is
geared up with special disassembly equipment for every various component according to every part’s characteristics.
The common trapezoidal quadruple thread is adopted to hook up the impeller and shaft, which not only
transmits strong torque but also is easy to disassembly.
(three)Great Functionality on NPSH:
The excellent NPSH efficiency of ZN variety pump guarantees the powerful suction ability as properly as deeper
dredging depth and denser dredging focus.
(4)Very good Put on-resistant Functionality, Long Services Time of Damp Areas:
Soaked elements of this sort of dredging pump-impeller, liner and front & back liner plate are adapted anti-dress in
cast iron alloy whose hardness is far more than 58HRC, who has both robust anti-attack feature and increased
resistance put on and resistance abrasion characteristics. The hardness of A31 materials that is researched and tested effectively by us can research 70HRC.
(5)Dependable Shaft Sealing With no Leakage:
The shaft of two hundred-500ZN dredging pump utilizes the mechanical sealing or stuffing sealing or mechanical-stuffing compound sealing. The shaft of 600-a thousand
ZN dredging pump adopts spiral sleeve L (shape) rubber sealing device that consists of three L sealing ring and a single specific thread shaft sleeve.
