Product Introduction
A positive displacement pump, the rotor pump features a pair of cams rotating in sync in opposite directions within its chamber. Our company has always been committed to integrating technology development with practical applications, continuously upgrading and refining our products. Based on years of research and experience, we have determined a series of rotor pumps suitable for different working conditions: chemical, food, and general-purpose types, among others. Depending on the specific working conditions and medium being transported, the pump is configured accordingly. This ensures that the rotor pump operates stably, efficiently, and safely across various applications, providing users with fluid transport solutions that meet actual working condition requirements.
Working Principle
The Helix rotor pump consists of multiple volume chambers formed by two rotors and the pump body. When the two rotors rotate synchronously in opposite directions, the volume chambers work cyclically—expanding to a smaller size, maintaining a fixed volume, and then contracting to a larger size—to achieve the purpose of conveying fluids. The motor and reducer drive the pump shaft, converting electrical energy into kinetic energy of the conveyed fluid medium through the pump. The flow rate of the pump depends on the volume of the working chamber and its change frequency per unit time, and is unrelated to the discharge pressure (theoretically and when ignoring the viscosity and fluidity of the material); the rotor pump, driven by a drive shaft and synchronized gears, allows two rotors to rotate synchronously in opposite directions. During rotation, the rotors and pump chambers form a fixed volume chamber. The volume chamber at the inlet expands from small to large, generating suction (vacuum) to吸入material, while the volume chamber at the outlet contracts from large to small, forming a conveying pressure to output the material. The volume chamber characteristics of the pump can effectively convey soft, easily broken solid materials with large particle sizes, such as fruit pulp particles in food materials.
