Heat conduction oil furnace is by circulating pump pressure into the heating system to meet the needs of the heating process, liquid heat conduction oil furnace and heating system pressure is determined by the pressure of the circulating pump, so in the HTF heating system heating The mode is a forced circulation of the liquid phase. The circulation pump plays a "heart" role in the circulation of the HTF throughout the heating system. If the circulation pump is stopped, circulation of the HTF will be interrupted. In order to achieve the forced circulation of the HTF in the heating system, a circulating pump must be provided in the system. According to the characteristics of the heat conduction oil furnace heating system, circulation pump in addition to the technical performance of the pump commonly used, the configuration and performance should meet the following requirements. 1. Circulation pump flow, head and power, and the heating system should be used to reduce the amount of oil and resistance requirements match. 2. The heating system should be equipped with two separate, and have their own source of power circulating pump, a reuse, a spare. 3. Circulation pump cavitation margin should be less than the circulatory system device NPS, in order to avoid cavitation pump operation. 4. Circulating pump hard seal reliable, prevent leakage, if found leaked, should immediately listen to pump inspection, repair. 5. Circulation pump inlet should be set coarse filter, where the thermal oil must be filtered to filter out impurities and foreign matter, the heating system should be installed on the bypass bypass fine filter, filtered suspended in the HTF Carbon and high polymer. Introduction of heat-conducting oil furnace circulation pump: RY series air-cooled high-temperature heat-conducting oil pump has reasonable structure, excellent performance and reliable operation. Suitable for conveying high temperature liquids without solid particles. RY series air-cooled high-temperature heat pump oil corrosion resistance and temperature depends on the media in contact with the main parts of the material. The advantages and features of circulating pump: RY series of air-cooled high-temperature heat transfer oil pump technology is advanced, high efficiency, long-term stable operation in the hot state no leakage, no additional cooling system, the use of safe and reliable, heating system in China Has been widely used, has entered the petroleum, chemical, rubber, plastics, pharmaceuticals, textiles, printing and dyeing, roads, food and other industrial fields, RY series air-cooled high temperature heat transfer oil pump is mainly used for conveying solid particles without weak rot High temperature liquid, the use of temperature ≤ 370 ℃, is an ideal circulating pump. The thermal oil pump widely used in high temperature paper lunch box stereotypes, dynamic vulcanized tire and reclaimed rubber machinery, flat vulcanization, rubber, drying, feed drying, printing and dyeing, chemical industry, plywood production, waterproofing membrane production, asphalt heating, noodle drying industry. (1) RY series air-cooled high-temperature heat-conducting oil pump is the second-generation product developed on the basis of digestion and absorption of foreign oil pumps. The basic structure is single-stage single-suction cantilever foot support structure. The center is vertical upward, and the motor is mounted on the base. (2) The RY-type heat-conducting oil pump is supported by a double-ended ball bearing structure. The front end is lubricated with grease and the rear end is lubricated with grease. The middle part has a guide pipe for observing the sealing and recovering the heat-conducting oil at any time. (3) RY series air-cooled high-temperature heat-conducting oil pump adopts self-heating and heat-dissipating structure, which changes the traditional water cooling structure, which makes the structure simple, small in size, saves operation cost, good performance and reliable operation. (4) RY series of air-cooled high-temperature heat-conducting oil pump with packing seal and mechanical seal combination form, packing seal with high temperature filler, has good thermal adaptability, and mechanical seal is the use of high mechanical strength, wear resistance Good cemented carbide material, to ensure the sealing performance under high temperature conditions. (5) RY series air-cooled high-temperature heat-conducting oil pump uses the third generation of polytetrafluoroethylene (referred to as PTFE) lip seal, the sealing performance has been a leap forward than the rubber seal reliability increased by 25 times the corrosion resistance .
