Sand slurry Submersible Pump
The First In TheWorld
——Submersible Sand-Pump
Allowance Diameter Passing Of Particle: 10mm
Allowance Specific Gravity Of Sand : 20%
The TurBulence Submersible Sand-Pump has been gradually adopted by many large or middle scale mines and drainage enterprises in last 25 years. Some previous generations have experienced the application tests for dealing with exploded rock and discharging sand, and greatly shorten the drainage cycle. The pump acts as an important role at the moment when water and sand are bursting out.
The BSQ explosion-free series and SQ general series are all the most brand-new research achievement. They comprise of three items of invention patent, several items of practical and new-type patent and the recent improvement for large-scale, high efficiency and saving energy.
The TurBulence Submersible Sand-Pump can be used for various sand-laden drainage conditions; High head, long service life, dealing with both water and sand, saving the operation duration., your first choice !
A New Theory Indicates a New Way
The Sample of Sand taken from Hukou
The design theory of the TurBulence Submersible Sand-Pump can be stems from a new model of hydromechanics. A brand-new concept of Submersible Sand-Pump after Ordinary Submersible Pump and Sewage Submersible Pump.
The pump is suitable for clear water, sewage, sand-laden water, and so on. This makes a vaster application field for submersible pumps and offers a new direction for future development of submersible pumps.
"The water of the Yellow River falls from the sky". The roaring torrent is laden with a large amount of sand at the Hukou section .
Ordinary submersible pump is not appropriate for dealing with this kind of water. The test sample of water is taken from Hukou section. The influence of sand in water on the generator and pump casing is under full consideration. Therefore the TurBulence Submersible Sand-Pump can be operated easily under this kind of unfavouraite environment.
Main Characteristics
Allowance Run without Water
The generator is set in an air chamber that is of a cup shape, and fixed in the water with the 'cup' bottom up and the mouth below to keep the air in the 'cup'. The stator, rotor and the bearing set are arranged inside the 'cup' in advance. Then the axe of generator stretches out from the mouth of the 'cap'. This is just the generator model for the TurBulence Submersible Sand-Pump.
With the protection of air chamber, the stator, rotor, bearings and axial seal can avoid directly contacting with water and harmful materials like sand, acid, alkali, etc.
During the process of drainage, because of the unique design of TurBulence Submersible Sand-Pump the operation without water is also allowed and does no harm on the generator and the pump. No man need assigned to monitor the pump.
A Unique Patent Technology
The design of a new-type impeller elevates the head of pump and avoids the internal stress. Special casing makes it easy to transport sand with the guide of water and improves the pump efficiency. The new structure makes it possible to separate gas and water and to run for a longer service life.
The casing ring and the impeller of the pump
Aboard Application
The casing ring and the impeller of the pump are made of horniness alloy. So the pump can void being damaged by sand and service for a long time.
The coil of generator is cast with heat-resistant epoxy resin, solidified and sealed. Thus the generator has got another protection, and is safer and more reliable.
The general application fields: automatic drainage for large mechanization mines, purification of ore selection; washing coal, mill running, panning; clearing silt and well, mine water storage house, dredging up river pass and reservoir; cleanup waste slag and ash powder at thermoelectricity mill.
Brief Introduction of Pump's Structure
Other Application
The vertical generator and pump share the same axe. The pump casing is below the generator (for the lowly fixed type). There are three forms of the TurBulence Submersible Sand-Pump: single-stage-single-suction, multistage single-suction and single-stage-double-suction. The axial seal, the easily damaged part the pump, is completely omitted for the three forms of pumps.
The suction of the pump impeller is set upwards for single-stage-single-suction form. The lower end of the pump casing is shut down.
The impeller of the first stage is at the top and its suction is set downwards for the multistage single-suction form. The lower end of the pump casing is shut up.
The impeller for single-stage-double-suction form has an up and a low suction.
The number of impeller for multistage pump is even. The impellers are set back on back. So there exists no axial force with this arrangement and there is no need for a balance plate that is the most easily damaged part of a multistage pump.
The shell of the generator is inside the guide jacket. The water discharged from the pump flows between the generator and the guide jacket, and can cools the generator. There is a stop valve set at the discharge end of the guide jacket; the sand in the pipe won't sink in the pump casing when the pump is stopped.
