Description   

QSZ submersible slurry pump is our factory technical personnel absorbing foreign advanced technology and combined with the actual situation of the majority of users, the design research and development, motor and pump coaxial integrated directly into the medium to work hydraulic machinery. The product is excellent selection, advanced structure, wide flow channel through ability, metallurgy, chemical, mining, power plants and other enterprise for conveying containing sand, cinder, tailings and other natural particles or liquids, it is the ideal alternative of traditional slurry pump . The products add a mixing impeller in the bottom by another except main impeller and can precipitate in the slag jet hit the water and solid particles into the mixing liquid, the pump in the case where no auxiliary means to achieve a transport of high concentration. Unique sealing

device can effectively balance the pressure inside and outside of oil chamber, making mechanical seal both ends of the pressure to maintain a balance, the maximum guarantee reliable operation of the mechanical seal, greatly prolonging its life, the motor according to user requirements increase water testing, overheating and other protection devices that make products for harsh working conditions for long-term safe operation.


Application 

1. Pumping tailing slurry for industrial and mining organizations;

2. Sucking silt in sedimentation basin;

3. Pumping silty sand or fine sand for seashore or port;

4. Pumping powdery iron ore for foreign countries, etc;

5. Deliver a solid particles of mud, larger pulp, coal slurry, sandstone, and other media;

6. Sucking from all kinds of fly ash power plant, coal slime 


Structure and operating principle   

QSZ type submersible slurry pump for the pump and motor coaxial , through the motor shaft driven pump impeller rotation when operation, the energy transfer to the slurry medium, thus producing a certain velocity, led solids flow to achieve slurry delivery.

Main features are as follows:

1. Machine is dry type motor pump structure. Motor adopt mechanical seal protection and can be

effectively prevent high-pressure water and contaminants into the motor cavity.

2. In addition to the main impeller, also equipped with mixing impeller and can be extracted residue

stirred into a turbulent precipitate at the bottom of the post . 

3. Impeller, mixing impeller and other major wet parts using high wear-resistant material

manufacturing, wear-resistant , corrosion resistance, non-clogging blowdown ability , can be

through larger solid particles effectively . 

4. No limitation by suction head , high efficiency suction slag , more thoroughly cleaning .

5. Without auxiliary vacuum pumps, investment cheaper.

6. No equipped with auxiliary mixing or spraying devices , operation more convenient . 

7. Motor submerged, without building complex ground protection and fixtures, management more

convenient and easy.

8. Mixing impeller direct contact deposition surface, control concentration through dive depth ,

therefore concentration control more comfortable. 

9. Device directly submerged to work, no noise and vibration, scene cleaner.


 

(1). Electrical wiring

(a) Pump power cables for the four cores, three power lines, a ground wire; pump equipped with a

protective device with corresponding control cables; pump cable cores have different functions

signage signs, see below table : In strict accordance with the identification card

cores indicated the same identity with the control cabinet wiring terminals. With a multimeter check

the ground wire core wire with the respective resistance values should be consistent with the

requirements of the table. Ground wire must be grounded.

(b) It should be always test insulation resistance during installation, detecting the motor insulation

resistance shall not be less than 5MΩ after descend the well ; Connect the electrical equipment will be

enabled.

(c) power-on , such as the pump less water , the pump may be connected in reverse, stop swap any

two connector of three-phase power cable .

(2). Install Way:

Installation for the mobile installation, the pump upright vertical suspended into the water, place

should be smooth; then fasten the cable, connect the pump outlet pipe; this method easy to install,

easy to move.

 

Operation condition   

1. Power supply 50Hz , 380V , 3-phase , ACpower .

2. The highest temperature of medium shall not exceed 40 ºC, the medium does not contain

flammable gases. 

3. The maximum volume of concentration solid particles is 30% in medium and the maximum

medium density is 1.2kg / L.

4. The unit maximum diving depth does not exceed the 20 meters, the minimum diving depth

to drown motor prevail.

5. Unit in the medium with vertical to work for good , operating mode for continuous operation.

Note: When site conditions does not comply with above provisions, please note when ordering, can

be customized according to requirements .
