The invention relates to an engine power system, and aims to provide a pneumatic and internal combustion hybrid system based on multi-stage utilization of afterheat of cooled water. According to the system, an air inlet pressure stabilization box of a pneumatic engine is connected with an air storage tank through a high pressure air pipeline; an air cylinder body and an air cylinder cover of a water-cooled internal combustion engine, a water pump and a pipeline form loop circulation; a circulation loop of the cooling water in the water-cooled internal combustion engine is divided into three stages; the first stage of the circulation loop is small circulation of the internal combustion engine body; the second stage of the circulation loop and the third stage of the circulation loop are respectively added into a pneumatic engine air cylinder and a water and air heat exchanger; and the stages of circulation loops are switched by turning on and turning off an electronic thermostat. The system makes full use of the afterheat of the cooling water in the internal combustion engine, so that the working environment of the pneumatic engine is improved, the circulation output power of the pneumatic engine is improved effectively, and the air consumption rate of the pneumatic engine is reduced finally; furthermore, the energy consumption of the internal combustion engine is reduced; and the dynamic property and the economy of the power system are improved.

The invention belongs to the technical field of ultra-pure material preparation, and particularly relates to a multifunctional electron beam zone melting furnace. The multifunctional electron beam zone melting furnace comprises an upper feeding and clamping mechanism 1, a furnace body 2, an electronic gun 3, a vacuum system 4, a rack 5, an electronic gun moving mechanism 6, a lower feeding and clamping mechanism 7, an observation window 8, a control box 9, a high-voltage power supply, an automatic control system and a water cooling system; and the end portion, extending into the furnace body 2, of the upper feeding and clamping mechanism 1 is an upper clamping head, and a to-be-melted bar is clamped at the upper clamping head. The function of synchronous coordinated movement of the gun body and the feeding and clamping mechanism can be achieved, diversification of smelting materials can be achieved, the structure is compact, the requirement for smelting of bars with the diameter of 50mm can be met, the layout is reasonable, and maintenance is convenient.

The invention provides a combined type air conditioning unit with double cooling systems, and relates to the technical field of combined type air conditioning units. The combined type air conditioning unit comprises an air conditioning unit body, a fan cover is fixed at the center of the top of the air conditioning unit body, the bottom of the fan cover penetrates into the air conditioning unit body, a filter screen is fixed at the top of the fan cover, and a plurality of supporting rods are arranged at the part, close to the edge positions, between the inner walls of the fan cover in the peripreral direction at equal distance. According to the combined type air conditioning unit, heat-conducting fins are arranged outside a water cooling box, a motor is arranged at the top of the combined type air conditioning unit, the motor drives fan blades to rotate to dissipate heat of the heat-conducting fins, and the heat dissipation efficiency is further improved in cooperation with water cooling. The problems that when a traditional combined type air conditioning unit is larger in regulation and control temperature difference, high-power operation is needed, at the moment, the heat generated by the combined type air conditioning unit during high-power operation cannot be taken away in time only through the water cooling, the heat of a compressor is continuously accumulated, and the service life of the compressor is affected are solved.

The present invention provides a roller manufacturing equipment, which includes a first mold and a second mold, a first support seat for carrying and installing the first mold, and a second support seat for carrying and installing the second mold; the first support The seat has a first preloading device for preloading the first mold and the second mold; in the actual use process, when the accuracy is reduced, the mold in the support seat can be replaced by installation and disassembly, thereby ensuring the accuracy of the pouring mold; When the support seat is closed, the first pre-tensioning device can provide additional closing pressure, so that the mold is closed more tightly, thereby improving the quality of the finished product; a roller manufacturing process of the present invention includes locking the support seat to fix the mold, pouring The molten iron is cooled and formed, the mold is opened to remove the burr, the surface is quenched by welding, and the inner hole is processed and assembled. The mold accuracy can be adjusted by changing the mold, the forming accuracy of the wheel blank can be improved, the mold can be rapidly cooled, and the manufacturing process of the rollers can be accelerated. Improve roller manufacturing efficiency.

The invention discloses a self-adaptive temperature control type high-voltage switch cabinet for a large-temperature-difference area, and relates to the technical field of high-voltage switch cabinets, and the self-adaptive temperature control type high-voltage switch cabinet comprises a switch cabinet main body, an electrical element assembled in the switch cabinet main body, and a switch cabinet door assembled on the back of the sun, and a water cooling assembly is assembled at the bottom end of the switch cabinet main body. A circulation assembly forming a cooling loop with the water cooling assembly is wound around the outer wall of the switch cabinet body, liquid in the circulation assembly is used for driving the transmission assembly to operate, and a protection assembly is assembled on the side, away from the switch cabinet body, of the transmission assembly. According to the invention, when the internal temperature of the switch cabinet main body is too high, the device main body automatically and rapidly cools the interior of the switch cabinet main body, and at the same time, external heat energy is isolated by means of kinetic energy generated in the cooling process, so that the internal temperature of the switch cabinet main body can be rapidly recovered to a specified threshold value under the protection of the two aspects.
