Abstract
Description
Technical Field
[0001] This utility model relates to the field of discharge pump technology, specifically a discharge pump with a connecting pipe jacket heat tracing structure. Background Technology
[0002] A discharge pump is a device used to transport materials such as liquids or gases from one place to another. Discharge pumps play a vital role in industrial production, environmental protection, and pharmaceuticals. They can separate materials containing solid particles, ensuring that the materials meet emission standards and guaranteeing production and environmental safety. In various application scenarios, such as the chemical, petroleum, and food industries, discharge pumps can improve production efficiency and reduce labor costs.
[0003] To reduce waste of manpower and resources, lower maintenance costs, and ensure stable operation of the plant, a discharge pump with a heat tracing structure and connecting pipe jacket is needed to transport liquid sulfur. Existing discharge pumps with this structure suffer from short operating cycles and frequent maintenance due to factors such as pump shaft material, shaft diameter, and medium viscosity. Each disassembly and inspection reveals damage to various components, particularly severe bending of the pump shaft. Frequent maintenance not only wastes manpower and resources but also causes frequent fluctuations in plant performance, seriously affecting stable operation. Furthermore, the existing discharge pumps with the heat tracing structure use 304 stainless steel for the pump shaft and have a small diameter. In unstable on-site conditions, excessive liquid sulfur viscosity can cause a surge in motor power, leading to prolonged overload operation, shaft bending, and bearing damage. Frequent and difficult maintenance results in equipment being unable to be readily available for standby. Utility Model Content
