Thickened浆 screw pumpDetailed Introduction

I. Overview of Dense Paste Screw Pumps

Thick浆 screw pump is a single-screw reciprocating pump that utilizes an eccentric single screw within a double-screw sleeve to move thick浆 fluid along the spiral groove from the suction port to the discharge port, thereby achieving the pump's conveying function.

II. Features of High-Consistency Slurry Screw Pumps:

1Capable of transporting high-concentration, high-viscosity suspensions with a viscosity of less than 10,000 PaS, as well as suspensions containing particles.
2. Stable liquid flow without overflow, pulsation, mixing, or shearing of slurry.
3. Flow rate is independent of pressure drop, high discharge pressure can be maintained even at low flow rates.
4. Flow is proportional to speed; flow regulation can be achieved through a variable speed mechanism or a speed control motor.
5. High self-priming capability; no need for a bottom valve, direct liquid suction is possible.
6. Pumps are reversible, allowing the direction of liquid flow to be changed with the rotation of the pump, suitable for applications where reverse and forward flushing of pipelines is required.
7. Smooth operation, low vibration, and minimal noise.
8. Simple structure with easy disassembly and maintenance.

Three, High-Consistency Screw Pumps – Application Range Examples: All components of this series of high-consistency pumps are made of high-quality stainless steel. The screw sleeve is made of medium-hard rubber, making this pump particularly suitable for use in the food processing industry, chemical industry, and more. For example:
1. Transport of molasses, syrup, bagasse, and beet pulp from sugar factories.
2. Packaging and conveying for canned and food factory products such as milk powder, starch, honey, coffee, milk, butter, edible oils, various vitamin liquids, maltose, tomato sauce/jam, mayonnaise, ice cream, etc.
3. Brewery beverage ingredients, spices, and fermentation broth; conveying of spent grain waste from press filters.
4. Delivery of fish liver oil, fish oil, fish flake, and fish meal from fish processing factories.
5. Fruit processing plant: conveying of syrups and juices, mashing of oranges and fruits, feeding materials for crushers, etc.
Packaging materials and auxiliary conveyance for edible oils, rice, cornstarch, and other products from oil and grain processing factories.
7. Meat processing plants, slaughter products; oil extraction, meat oil, packing, and transportation of waste liquids.
8. Transportation of additives for various vitamin liquids, pharmaceutical liquids, and emulsions; conveyance of suspensions, saline solutions, sludges, and pharmaceutical residues.
Chemical Industry: Transport of acids and alkaline liquids, various suspensions, oils, gums, a variety of chemical dyes, paints, various adhesives, ointments, and pastes. Particularly, materials with high viscosity that general centrifugal pumps cannot handle, or those containing solid particles, can all be transported by this pump.
10. Ingredients supply for printing inks.
11. Paper mill pulp and ink slurry conveyance
12. Oil and petrochemical products, as well as the conveyance of oils, fats, waste liquids, and sludge from refining plants.
13. Transport of calcium carbide sludge from acetylene stations.
14. Supply of plaster, lime milk, mortar, cement slurry, and other construction industry materials.
15. Suitable for pumping water, conveying in feed processing, and loading/unloading operations.
16. Widely used in industrial and domestic wastewater and sludge treatment; wastewater often contains many suspended solids with some corrosiveness and viscosity, often containing solid particles, thus, the use of thick slurry pumps for conveyance is appropriate.
17. Transport of polluted water, polluted liquids, and other materials for nuclear power stations.
18. Mine drainage and sludge.
Additionally, it can be used in the steel industry, shipbuilding, ceramics, and leather processing water plants.

Four, Dense slurry screw pump structural material form:

I-1BBType: Shell castings and drive components (main shaft, screw, and shaft) are made of 2Cr13 stainless steel, suitable for general neutral thick slurry transportation, as well as general slightly acidic and alkaline slurry transportation.
I-1BF Model: Both the transmission parts and the pump casing that comes into contact with the slurry are made of stainless steel, suitable for conveying food and corrosive slurries.
Rubber bushes are available in general wear-resistant rubber, food-grade rubber, and oil-resistant rubber for customer selection.
Transmission methods include direct transmission between the motor and pump shaft, motor transmission to the pump via a reducer, and motor transmission to the pump shaft via a V-belt pulley.
Available electrical motors include general enclosed, explosion-proof, and electromagnetic speed control types, along with variable speed drives and gear reducers for customer selection.
