This invention discloses an induction heating system for heat-fitting an energy-saving centrifugal pump impeller, comprising a positioning mechanism, a heat-fitting mechanism, a heating induction mechanism, and a control system. The positioning mechanism fixes the pump shaft and guides the movement of the slide. The heat-fitting mechanism drives the slide to translate along the positioning rod via a drive assembly. The heating induction mechanism includes a rod-shaped first heating assembly and a spiral disc-shaped second heating assembly, which independently induction heat the impeller's inner bore and side surface, respectively. The control system includes a first temperature sensor for collecting the temperature of the impeller's inner bore and a second temperature sensor for collecting the temperature information of the impeller's side surface. The system controls the operation of the first heating assembly, the second heating assembly, and the drive assembly in real time based on the feedback information from the first and second temperature sensors. This invention, through zoned independent heating and temperature difference regulation, ensures effective expansion of the inner bore, avoids end face warping and inner bore taper deformation, effectively prevents impeller jamming and pump shaft scratches, and improves the success rate of heat-fitting.

This invention relates to a heat treatment device and method for separating roller shafts and roller sleeves, comprising a first base, a first lifting mechanism, an upper center, a second base, a first mounting base, a receiving component, a lower center, a second lifting mechanism, and a heating induction coil. The first mounting base has a first through hole for the lower center to pass through, and the first mounting base is fitted over the lower center. The receiving component has a second through hole for the lower center to pass through, and the receiving component is mounted on the first mounting base and fitted over the lower center. The heating induction coil heats the outer surface of the roller sleeve, causing the roller sleeve to separate from the roller shaft. The receiving component catches the fallen roller sleeve. Unlike existing technologies, this invention does not require damage to the roller shaft; both the roller shaft and roller sleeve can be reused. It has a short processing cycle, saves significant processing costs, and enables rapid separation of the roller sleeve and roller shaft.

This invention relates to the field of steel ball manufacturing technology, and particularly to a high-efficiency quenching process for steel ball manufacturing. The process sequentially includes raw material pretreatment, segmented preheating, induction heating, three-dimensional flow-guided quenching, two-stage tempering, surface residual compressive stress strengthening, online detection, and quenching medium circulation regeneration. This ensures that the internal structure of the steel ball is fully austenitized before entering the quenching tank. A high-speed circulating polymer aqueous solution quenching structure is used, allowing the steel ball to achieve a rapid and uniform cooling rate under the action of three-dimensional eddies, effectively reducing quenching cracks and microstructure inhomogeneity. Two-stage tempering combined with high-pressure rolling strengthening forms a deep compressive stress layer on the surface. Through closed-loop control of temperature, flow rate, vacuum degree, and data acquisition, this process significantly improves the hardness consistency of the steel ball, reduces the probability of quenching deformation and defects, and produces products with high precision, dense microstructure, and long fatigue life. It overcomes the problems of high energy consumption, low efficiency, and unstable quality associated with traditional intermittent quenching.

This utility model discloses a router with improved heat dissipation, including a casing with heat dissipation holes on the bottom and side walls. It also includes a heat dissipation assembly, a support assembly, and a thermal sensor. The heat dissipation assembly is located at the heat dissipation holes and includes an air diffuser, a wind deflector, and a fan positioned between the diffuser and the deflector. The diffuser has an inlet end and an outlet end; the inlet end is connected to the bottom surface of the casing and communicates with the heat dissipation holes, while the wind deflector is located at the outlet end. The support assembly is located at the bottom of the casing and can adjust the height of the casing. The thermal sensor is located inside the casing and is used to monitor the internal temperature in real time. When the temperature detected by the thermal sensor gradually increases and exceeds a set temperature value, the support assembly gradually raises the height of the casing. When the support assembly drives the casing to rise to the set height, the fan starts. This improves heat dissipation efficiency and effectively prevents the router from experiencing performance degradation or damage due to excessive internal temperature.
