450WN/500WN model massive stream sound sand dredge pump
one.Item description
ZD Dredge Pumps are solitary-stage solitary suction cantilever horizontal centrifugal pumps with benefits of light-weight bodyweight, great put on-resistant,
tremendous dredging performance, ZD dredging pumps impeller passage is very extensive, It can constantly transport gravels or high plastic clay and not
takes place jam, especially for dredging sands and damming of the river and seas.
ZD Sequence Dredge Pumps can be also integrated with the gearbox, that mean the pump and gear box share 1 widespread shaft.
So It isn’t going to need to have the pump bearing assembly and body, In this way, not only conserve space, but also minimize cost and breakdown ratio,
let the dredge pump give enjoy to optimum usefulness.
It is a new variety of River Dredging sand Pump investigated and manufactured by our business aiming at the dredging and damming of the river or lakes.
2.Product attributes and performance parameters
(1)Structure suited for dredging ship:
The structure of 200ZD-500ZD type pumps are single-casing, single-phase, one-suction, cantilever
and horizontal. According to the relationship with the equipment box, two constructions can be offered: self-carrying
bracket and pump-box assembly. The lubrication for the bracket isgrease or slim oil.
The framework of 600ZD-1000ZD type pumps are double-casing, solitary-stage, one suction, cantilever and
horizontal. It has self-carrying bracket. Lubrication is pressured slender oil lubricating. The double-casing design
can guarantee the liner can work till it is worn out, and if the liner crack, drinking water can not enter into the pump.
(2)Effortless to Disassembly and Installation, Convenient Routine maintenance:
ZN kind pump adopts front-disassembly structure in favor of easy disassembly and servicing. Also it is
outfitted with special disassembly resources for each and every distinct element according to each part’s features.
The standard trapezoidal quadruple thread is adopted to join the impeller and shaft, which not only
transmits strong torque but also is effortless to disassembly.
(three)Very good Overall performance on NPSH:
The very good NPSH performance of ZN type pump assures the strong suction potential as properly as deeper
dredging depth and denser dredging concentration.
(4)Very good Wear-resistant Efficiency, Extended Services Time of Soaked Elements:
Damp parts of this kind of dredging pump-impeller, liner and entrance & again liner plate are adapted anti-dress in
cast iron alloy whose hardness is far more than 58HRC, who has equally strong anti-assault attribute and greater
resistance dress in and resistance abrasion features. The hardness of A31 material that is investigated and tested successfully by us can investigation 70HRC.
(five)Dependable Shaft Sealing Without Leakage:
The shaft of 200-500ZN 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 (condition) rubber sealing device that consists of a few L sealing ring and 1 unique thread shaft sleeve.
