WN450 dredging sludge pump for transport river sand
1.Solution description
ZD Dredge Pumps are single-phase solitary suction cantilever horizontal centrifugal pumps with benefits of gentle bodyweight, excellent dress in-resistant,
super dredging functionality, ZD dredging pumps impeller passage is very broad, It can constantly transportation gravels or higher plastic clay and not
takes place jam, specifically for dredging sands and damming of the river and seas.
ZD Series Dredge Pumps can be also integrated with the gearbox, that suggest the pump and gear box share a single frequent shaft.
So It will not need the pump bearing assembly and body, In this way, not only save place, but also lessen value and breakdown ratio,
permit the dredge pump give enjoy to optimum efficiency.
It is a new variety of River Dredging sand Pump researched and manufactured by our business aiming at the dredging and damming of the river or lakes.
2.Solution attributes and overall performance parameters
(1)Structure suited for dredging ship:
The construction of 200ZD-500ZD type pumps are single-casing, single-phase, single-suction, cantilever
and horizontal. In accordance 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 thin oil.
The construction of 600ZD-1000ZD type pumps are double-casing, one-phase, one suction, cantilever and
horizontal. It has self-carrying bracket. CZPT is forced slender oil lubricating. The double-casing design
can make certain the liner can function until it is worn out, and if the liner crack, drinking water can not enter into the pump.
(two)Simple to Disassembly and Installation, Practical Maintenance:
ZN kind pump adopts front-disassembly structure in favor of easy disassembly and routine maintenance. Also it is
geared up with specific disassembly resources for each distinct component according to every part’s attributes.
The CZPT trapezoidal quadruple thread is adopted to connect the impeller and shaft, which not only
transmits strong torque but also is simple to disassembly.
(3)Great Efficiency on NPSH:
The good NPSH overall performance of ZN type pump ensures the powerful suction capability as well as deeper
dredging depth and denser dredging concentration.
(four)Great Dress in-resistant Overall performance, Extended Support Time of Moist Parts:
Soaked elements of this type of dredging pump-impeller, liner and front & again liner plate are adapted anti-wear
cast iron alloy whose hardness is a lot more than 58HRC, who has both robust anti-assault function and greater
resistance wear and resistance abrasion characteristics. The hardness of A31 substance that is investigated and tested effectively by us can research 70HRC.
(five)Dependable Shaft CZPT Without having Leakage:
The shaft of two hundred-500ZN dredging pump makes use of the mechanical sealing or stuffing sealing or mechanical-stuffing compound sealing. The shaft of 600-a thousand
ZN dredging pump adopts spiral sleeve L (form) rubber sealing system that consists of 3 L sealing ring and a single special thread shaft sleeve.
