Structural Features
Rotor Design
The rotors of the lobster paste rotor pump usually adopt special geometric shapes, such as double-lobe, triple-lobe or multi-lobe rotors. These rotors closely cooperate with the pump casing during the rotation process and can effectively transport high-viscosity materials like lobster paste. For example, when the triple-lobe rotor rotates, it can divide the pump cavity into several small sealed chambers, enabling the lobster paste to be pushed smoothly and reducing the fluctuations and pulsations of the material during the transportation process.
Pump Casing Structure
The pump casing is generally made of stainless steel materials (such as 304 or 316L). This kind of material has good corrosion resistance and can adapt to the salt and other components in the lobster paste. The flow channel design inside the pump casing has been optimized to reduce resistance and ensure that the lobster paste can pass through smoothly. Meanwhile, the structural strength of the pump casing is sufficient to withstand a certain amount of pressure and prevent leakage during the filling process.
Sealing System
In order to prevent the leakage of lobster paste, the rotor pump is equipped with an efficient sealing system. Mechanical seals or packing seals are usually adopted. The mechanical seal has good sealing performance, can effectively prevent the material from seeping out, and has a relatively long service life. The packing seal has a certain degree of elasticity and can adapt to the slight vibration and displacement of the rotor.
Working Principle and Advantages
Working Principle
The lobster paste rotor pump operates through a pair of rotors that rotate synchronously. When the rotors rotate, they will form a series of constantly changing sealed chambers inside the pump casing. At the suction end, the volume of the chambers increases, creating a negative pressure to suck in the lobster paste. As the rotors continue to rotate, the chambers move towards the outlet end, and the volume gradually decreases, squeezing out the lobster paste. This volumetric working mode enables the rotor pump to precisely control the transportation volume of the material, which is very beneficial for operations with high precision requirements such as filling lobster paste.
Advantages
High-Precision Metering: The flow rate of the lobster paste can be precisely controlled. By adjusting the rotation speed and rotation time of the rotors, high-precision filling can be achieved. For example, in the filling of some high-end lobster paste products, the filling error can be controlled within ±1%, ensuring the consistency of product quality.
Good Material Adaptability: Whether it is high-viscosity lobster paste or lobster paste containing certain particles, it can be smoothly transported by the rotor pump. This is because the clearance between the rotor and the pump casing can be adjusted according to the characteristics of the material, and the rotation mode of the rotor can effectively handle materials with different textures.
High Stability: During the long-term working process, it can maintain a stable flow rate and pressure. For the continuous production line of lobster paste filling, this can ensure the stability of the filling speed and quality, and reduce the filling errors and equipment failures caused by fluctuations in flow rate and pressure.
Application Scenarios and Selection Suggestions
Application Scenarios
Food Processing Enterprises: In the production and filling process of lobster paste, the rotor pump is one of the core equipment. It can transport the lobster paste from the storage tank to the filling head, realizing efficient and precise filling. Meanwhile, it can also be used in the production of other high-viscosity food sauces, such as crab roe sauce and shrimp paste.
Catering Industry: If some large catering enterprises need to make lobster paste-related dishes in batches or package the lobster paste into small portions for customers to buy, the rotor pump can also be used for the sub-packaging of lobster paste.
Selection Suggestions
Flow Rate Requirements: Select an appropriate flow rate model according to the production scale and filling speed requirements of the enterprise. If it is a large-scale lobster paste production enterprise, it is necessary to choose a rotor pump with a larger flow rate to meet the requirements of high production volume.
Precision Requirements: For enterprises with extremely high requirements for the filling precision of lobster paste, such as high-end brands or export-oriented enterprises, it is necessary to choose a rotor pump with high-precision metering functions, and pay attention to its control mode, such as whether there is an advanced servo control system to ensure the precision.
Hygiene Standards: Since lobster paste is food, it is necessary to ensure that the rotor pump meets the food hygiene standards. The pump body and the parts in contact with the material should be made of food-grade stainless steel materials, and they should be easy to clean and disinfect, such as the pump body being able to be disassembled and the seals being easy to replace.
