The conveying principle of the spiral centrifugal pump developed by?TNT-group?Fluid Technology is the characteristic of the spiral centrifugal pump: the spiral centrifugal pump combines the advantages of traditional centrifugal pumps and Archimedes spiral pumps, hence it is called the spiral centrifugal pump.. The hydraulic part of a spiral centrifugal pump mainly consists of a vortex shell, a suction port, and an impeller. The suction port is conical, and the suction port and vortex shell form a shell. The impeller is installed inside the shell and extends axially along a spiral curved surface to the front end of the suction port. The spiral centrifugal impeller is the core part, consisting of a spiral part and a centrifugal part. Spiral part in. Provides good suction capacity and low cavitation allowance requirements. The centrifugal part converts energy into pressure energy. After entering the volute, the liquid flow is discharged through the outlet on the volute due to the centrifugal part. The length of the spiral centrifugal impeller is 3-5 times that of the traditional single channel impeller for conveying solids. In this way, energy is gradually transferred to the liquid along the entire length of the impeller, resulting in lower surface pressure on the impeller. The low energy gradient and large curvature of the blades keep the flow state of the water unchanged throughout the entire process of passing through the impeller, with a gentle flow velocity, low shear, and low disturbance. This unique design gently transports liquid from the inlet to the outlet, saving energy and causing minimal damage to the blade surface. ★ Scope of use: Suitable for conveying medium with low to medium viscosity, mixed multi-phase flow media containing solid particles (designed to transport 30-80MM particles), and process technologies that require protection of particles in the medium from damage. Various fiber media such as cotton pulp, wood pulp, cloth strips, ropes, kelp knots, etc., need to be gently transported for fish, shrimp, clams, crabs, sewage, feces, and other fluids that are not suitable for centrifugal high-speed impact. ★ Advantages: Spiral centrifugal pumps are more reliable, superior, economical, and efficient in harsh conditions, and most importantly, they do not damage fragile media. They also transport particles, long fibers, and slag without entanglement, blockage, or fiber loss. There is no need for too many parts to be replaced or repaired. Widely used in industries such as pharmaceuticals, biotechnology, chemical wastewater, wine, starch, paper-making. |
