Working Principle
The rotary pump is a type of positive - displacement pump, consisting of a rotating rotor and a stationary pump body. It has no suction or discharge valves. The working volume is changed through the relative motion between the rotor and the pump body. The liquid is discharged by the squeezing action of the rotating rotor. At the same time, a space is left on the other side, creating a low - pressure area, enabling the liquid to be continuously sucked in.
Structural Features
Pump Body: Generally made of stainless - steel material, it has good corrosion resistance. It can adapt to the characteristics of konjac materials and meet the requirements of food hygiene. Meanwhile, it can withstand a certain amount of pressure.
Rotor: Common forms include cam rotors and gear rotors. The design of its shape and size will affect the performance of the pump, such as flow rate, pressure, and delivery efficiency. For the transportation of konjac materials, the rotor usually adopts a special design to reduce the shearing and damage to the materials and ensure the quality of the materials.
Sealing Device: To prevent material leakage and ensure the normal operation of the pump, the rotary pump is usually equipped with sealing devices such as mechanical seals or packing seals. For the transportation of food - grade konjac, mechanical seals are more commonly used. They have good sealing performance and a long service life, which can effectively prevent material leakage and the entry of external impurities into the pump.
Application Scenarios
Food Processing: In the production process of konjac products, such as the making of konjac tofu and konjac noodles, konjac powder needs to be mixed and stirred with water, etc. into a paste or liquid state, and then transported to the next process for processing. A konjac rotary pump with a flow rate of 5 cubic meters per hour can meet the production needs of small - and medium - scale konjac food processing enterprises, stably transporting the prepared konjac materials to equipment such as cooking and shaping equipment.
Chemical Industry: In the production of chemical products such as konjac gum, the konjac raw materials need to be dissolved, mixed, etc., and then transported to a reaction kettle or other equipment for further chemical reactions or processing. This rotary pump can accurately control the flow rate, ensuring the stability of the production process and the consistency of product quality.
Selection Key Points
Flow Rate and Head: Determine the required flow rate and head according to the actual production needs. A flow rate of 5 cubic meters per hour is a basic parameter, but factors such as pipeline length, delivery height, and resistance loss also need to be considered for their impact on the head to ensure that the pump can operate normally under actual working conditions.
Material Characteristics: Konjac materials have a certain viscosity and special physical and chemical properties. A rotary pump suitable for transporting high - viscosity materials needs to be selected, and attention should be paid to the material of the pump and its sealing performance to prevent material leakage and pump corrosion.
Hygiene Requirements: If it is used in the food processing industry, a rotary pump that meets food hygiene standards must be selected, such as using food - grade stainless - steel material and a structural design that is easy to clean and disinfect, to ensure food safety.
