Problems solved by technology

When the rotational speed exceeds 800r / min, the motor and the rotating spindle vibrate obviously, and the impeller appears unstable during operation
[0005] (2) The shape of the impeller is disc-shaped or simple cross-shaped blade, which has poor wear resistance and corrosion resistance, short service life, and needs frequent replacement and maintenance
[0006] (3) The shape and structure design of the impeller is unreasonable, and the effect of stirring the slurry is not ideal

Abstract

The invention provides a combined impeller of a rotating-type erosion test apparatus, belonging to the field of stirring equipment. The combined impeller comprises an upper blade, a connecting sleeve, a lower blade, upper screws and lower screws, wherein the upper blade is of an eight-blade tooth-shaped structure, the lower blade is of a six-blade tooth-shaped blade structure, the upper blade is fixed at the upper end of the connecting sleeve by virtue of the upper screws, the lower blade is fixed at the lower end of the connecting sleeve by virtue of the lower screws to form the combined impeller, the combined impeller is installed on a motor main shaft, and the motor main shaft is driven by a servo motor to stir slurry in a tank. Compared with an ordinary stainless steel material impeller, the weight of the impeller is remarkably reduced, the impeller and the main shaft run stably in the high-speed erosion test process, safety and reliability are realized, the service life of the motor is prolonged, and the wear resistance and corrosion resistance are relatively good. By adopting a split-type structure design, the combined impeller is convenient to repair and replace.

Description

Technical field: [0001] The invention belongs to the field of stirring equipment, and in particular relates to a combined impeller of a rotary erosion and abrasion test device, which is suitable for the stirring occasions of liquid-solid two-phase fluid that prevents solid particles from settling. Background technique: [0002] The erosion and abrasion phenomenon of liquid-solid two-phase flow is common in metallurgy, chemical industry, mining, hydropower and other industries. It is an important cause of rapid damage to various slurry pumps, valves, pipelines and other flow-through components. According to different working conditions, it is important to use appropriate erosion and wear devices and methods to study the erosion and wear laws and mechanisms of liquid-solid two-phase flow, rationally select materials and protections for the flow components, reduce the damage speed of the flow components, and extend the service life. significance. There are mainly four types of liqu...
