Problems solved by technology

However, there are still many deficiencies in the application process of the centralized lubrication system: this device can realize the flow heating of the grease medium during the grease delivery process, but the thermal conductivity of the grease is poor, and the spiral rotation speed is too fast. Grease heating effect deteriorates

Embodiment Construction

[0025] Through the description of the embodiments below, the specific implementation of the present invention includes the shape, structure, mutual position and connection relationship between the various parts, the function and working principle of each part, the manufacturing process and the operation and use method of the various components involved. etc., to make further detailed descriptions to help those skilled in the art have a more complete, accurate and in-depth understanding of the inventive concepts and technical solutions of the present invention.

[0026] Grease has significant thermal rheological properties. As the temperature rises, the medium viscosity of the grease decreases, and the pipeline resistance during the flow process decreases. In addition, the grease has relatively obvious wall slip characteristics. The higher the temperature, the more wall slip The more significant the effect, the more obvious the drag reduction effect on grease. Based on this, th...

Abstract

The invention discloses a heating grease supply device and a method. The heating grease supply device is provided with a grease storage pressurizing module and a heating grease supply module, wherein the grease storage pressurizing module is used for storing not heated lubricating grease and applying certain pressure to the lubricating grease; and the heating grease supply module is provided with a grease passing gap allowing the lubricating grease in the grease storage pressurizing module to be heated, hot fluid channels uniformly distributed at the outer edge of the grease passing gap and a grease outlet for collecting the heated lubricating grease, and the grease outlet communicates with the grease passing gap. According to the heating grease supply device, a wall slip effect of the smooth wall surface of the grease passing gap and the thermorheological characteristic of the lubricating grease during heating both have a promotion effect on the flowing property of the lubricating grease; meanwhile, the higher the temperature is, the more obvious the wall slip effect is; and through the coupled promotion effect, the gap flowing performance of the lubricating grease can be improved.

Description

technical field [0001] The invention belongs to the technical field of mechanical design, and relates to a heating grease supply device and method, in particular to a heating grease supply device and method based on the coupling effect of grease wall slip effect and thermal rheological characteristics. Background technique [0002] Grease is a semi-solid colloid, which is an ideal fluid lubrication medium and is widely used in industry. However, the high viscosity and poor fluidity of the lubricating medium make the lubricating grease face large pipe resistance and poor pumping performance during the filling process, especially the NLGI 2 and NLGI 3 lubricating greases commonly used in mechanical equipment and with high consistency grades . [0003] In view of the characteristics of high viscosity and poor fluidity of grease, the unique medium performance of grease needs to be considered during the pumping process of grease. In order to ensure that the grease has good pump...
