Cutter Suction Dredger River Sand Dredging Machine

Product Description

>> Overview for Cutter Suction Dredger River Sand Dredging Machine

AMG Series dredge pump is designed to handle very large particles for gravel and dredging operations.

Dredge pump is designed for the continuous handling of the most difficult higher abrasive slurry, containing solids too large to be pumped by a standard slurry pump.

These dredge pumps are constructed of a single casing connected by means of clamps and a widened suction port.

>> Features about Cutter Suction Dredger River Sand Dredging Machine

Wet parts	IMPELLERS – Dredge pump out vanes on rear and front (on closed impellers) reduce recirculation within pump, and in preventing seal contamination – optional castings of straight or semi-Francis vanes (from 3 to 8 vanes on certain sizes) offer wider hydraulic options in single sizes
NPSH	- exceptional NPSHr conditions due to large impeller eyes
Particles	- large eye openings and vane passages allow for the largest particle flows of any dredge pump
Seals	We offers a wide variety of seal options to suit any process requirements EXPELLER (CENTRIFUGAL SEAL) –available with low flow water flush or zero flow (grease lubricated) options to provide exceptional sealing where water introduction to the seal is intolerable or limited STUFFING BOX –gland sealing with packing and lantern ring LOW-FLOW SEAL –We offers a variety of low-flow seals, which can significantly reduce water usage in the stuffing box – the low-flow seal systems can be applied in a variety of applications using several material and component options
Bearing Assembly	- all bearings assembled with highest quality tapered roller bearings in controlled environments to prevent lubricant and housing contamination – oversized shaft diameters and reduced overhang in the wet end contribute to long life and reliability in the field
Base	– a single piece base with integrated adjustment mechanism for impeller clearance within pump – bearing assembly locks into base using four heavy-duty bolts – three custom designed mounting modes available: overhead using integrated single pedestal system, side-by-side with adjustable motor mount, and direct-coupled with precision in-house alignment (optional VFD packages available)

FAQ

>> Centrifugal dredge pump power loss

There only a part of the mechanical power of the centrifugal pump getting from the driver equipment, convert to the centrifugal power and then delivered to the liquid power. The another part was loss. The reasons are below:

1. Hydraulic loss: Created for the liquid impact, vortex and friction in the pump. The impact and vortex hydraulic loss is because of the the liquid change the flow direction. Besides, when the liquid flow, it will have friction when meet the pump passageway.This kind of loss depend on the length, volume, shape, and surface roughness of the passageway and the liquid flow speed and other character.

2. Volume loss: It resulted for the powered liquid will channeling are leakage. The general pump volume efficiency is 0.93~0.98%. Improve the seal ring and shaft seal construction, can reduce the volume loss and increase the volume efficiency.

3. Mechanical loss: It is caused by the friction of liquid and impeller plate surface, also named dick friction loss of impeller, and the pump shaft friction when rotated in the packing, bearing, balancing parts and other mechanical parts.
