This invention discloses a molten salt pump with a bearing cooling system, belonging to the technical field of high-temperature molten salt pumps. It includes: a pump body, a pump shaft, a frame, a bearing housing, a cooling device, and a support frame. The pump body is mounted on the frame; the frame is mounted on the top of the pump body, and the bearing housing is mounted within the frame. The pump shaft is rotatably connected to the bearing housing via bearings. The cooling device is installed inside the bearing housing, with multiple microchannel coils respectively fitted onto the outer surface of the bearing. A flywheel energy storage device is installed inside the bearing housing, driving ambient air to enter through the air inlet and generating a forced airflow that blows across the cooling end of the cooling device for heat exchange. The cooling end of the cooling device is connected to a cold air inlet pipe, which is connected to multiple microchannel coils, and all microchannel coils are connected to an outlet pipe. An outlet is provided at the bottom of the bearing housing, and the outlet pipe is connected to the outlet. This invention miniaturizes and integrates a compressor-free cooling device into the bearing housing for active phase change cooling, extending the lifespan of the molten salt pump.

This utility model provides a rotatable work light, relating to the field of lighting technology. The control device is housed within the lampshade and includes multiple first lamp groups and a conical knob. Rotating the conical knob controls the first lamp groups to extend or retract axially along pre-drilled holes in the lampshade. When extended, the first lamp groups are in an active state; when retracted, they are in a non-active state. The control device also includes a screw, a base, a base fixing rod, a slider, a conical knob cover, and a second lamp group. The switching device includes a connecting block, a fixing block, a limiting block, a sliding plate, a spring fixing rod, a spring, a rack, a switch control block, an encoder, gears, and a main shaft, enabling the extension and retraction of the first lamp groups to synchronize with the switching of the second lamp group, and adjusting the brightness of the first lamp groups via the encoder. Furthermore, a folding frame is included to support the work light. This utility model is easy to operate, offers flexible lighting, and has a compact structure, improving work efficiency and portability.

This utility model discloses a detachable headrest device for drivers and passengers, relating to the field of driving and passenger product technology. It includes a main body, a side pillow, and a side pillar. The side pillow is mounted on the side pillar, which is slidably mounted on the side of the main body. An elastic locking mechanism is provided between the side pillar and the main body. The elastic locking mechanism includes an elastic clip, and a slot is provided on the side pillar. The elastic clip engages with the slot, and pressing the elastic clip releases the engagement. By pressing the elastic clip, it deforms and disengages from the slot, allowing the side pillar to be removed from the main body. Reinstallation is simple: press the elastic clip, insert the side pillar, and release to re-engage the clip. Both installation and disassembly are convenient and quick. Users can customize the side pillow's style to meet their individual needs. Multiple slots are provided on the side pillar for easy adjustment of the side pillow's left and right position.

The utility model discloses a color paint stirring device of convenient unloading mechanism, including support connecting frame still including setting mobile wheel at support connecting frame bottom, setting stirring jar body in support connecting frame inside, fixedly connected installation connecting seat of support connecting frame one side. Solve the problem of serious raw material waste when traditional device unloads, reduce the additional solvent needed for cleaning, reduce the cost. At the same time, reduce the residual time -consuming cleaning, shorten the unloading and cleaning time, improve production efficiency, avoid the delay of construction period when cleaning during multiple batch production. In addition, reducing the residual can prevent the pollution of the next batch of materials, ensure the stable product quality, reduce the risk of scrapping caused by deterioration, also can reduce the corrosion and wear of color paint residual to equipment, reduce mechanical failure, reduce maintenance cost, prolong the service life of equipment, also reduce the security risk of manual cleaning contact with harmful substances, reduce the labor intensity, be favorable to production management and improve enterprise competitiveness.

The oil gun assembly comprises an oil gun and an oil supply pipeline, the oil gun is installed in the stable combustion shell, faces the opening and is used for spraying fuel oil, one end of the oil supply pipeline communicates with the oil gun, the other end of the oil supply pipeline extends out of the combustion chamber, and the part, located on the outer side of the combustion chamber, of the oil supply pipeline communicates with a cooling gas pipeline for introducing cooling gas into the oil supply pipeline; the ignition gun assembly comprises an ignition gun, the ignition gun is installed in the stable combustion shell and close to the oil gun, an advancing and retreating structure can be omitted, the response time is shortened, a cooling gas pipeline is additionally arranged, the oil gun is prevented from being burnt out, the stability of equipment is improved, and the service life of the equipment is prolonged.

The invention discloses a wear-resistant coating for a bearing and a preparation method and application thereof.The wear-resistant coating at least comprises polyamide-imide resin powder containing hydrophobic groups, a lubricating phase and a modified reinforcing phase, and the modified reinforcing phase comprises a modified fibrous reinforcing phase and a modified powdery reinforcing phase; the modified fibrous reinforced phase is prepared by degumming, etching and treating a fibrous reinforced phase with a coupling agent, and the modified powdery reinforced phase is prepared by carrying out surface pretreatment and acidizing treatment on a powdery reinforced phase. Compared with a conventional polyamideimide resin wear-resistant material, under the combined action of the polyamideimide resin powder containing hydrophobic groups, the lubricating phase and the modified reinforcing phase, the coating has lower water absorption, better self-lubricating property and higher bearing capacity, and can be widely applied to manufacturing of bearings; not only can the use requirement of a high-humidity environment be met, but also mechanical faults can be obviously reduced, so that the service life of the bearing is longer.
