导热油泵密封特点：采用填料密封和机械密封相结合的形式，填料密封用耐高温的填料，具有良好的热态适应性，而机械密封则采用机械强度高，耐磨性好的硬质合金材料，保证了高温情况下的密封性能。 Heat-conducting oil pump seal features: The combination of filler seal and mechanical seal, high temperature resistant filler for filler seal, has good thermal adaptability, and mechanical seal uses high mechanical strength, good wear resistance hard alloy material To ensure the sealing performance under high temperature conditions.
采用进口聚四氟乙烯做唇形密封，使密封性能产生了飞跃，比橡胶类密封可靠性提高25倍，耐腐蚀性能极强。 The use of imported polytetrafluoroethylene as a lip seal makes a leap in sealing performance, which is 25 times more reliable than rubber seals and has extremely strong corrosion resistance. 热油泵的轴承是浸没在输送介质中，并用输送介质润滑和冷却一般选用耐腐蚀、高强度的工程塑料、刚玉陶瓷、不锈钢等作为制作材料。 The bearing of the hot oil pump is immersed in the conveying medium, and is lubricated and cooled with the conveying medium. Generally, corrosion-resistant, high-strength engineering plastics, corundum ceramics, stainless steel, etc. are used as production materials.
国内较为常用的轴承多为石墨和增强塑料。 The most commonly used bearings in China are graphite and reinforced plastics. 石墨特别是浸渍石墨具有良好的自润滑性、耐热腐蚀、摩擦系数低、应用范围很广，但石墨较脆，强度也较低，对轴的弯曲和局部过载很敏感，应特别注意。 Graphite, especially impregnated graphite, has good self-lubricity, heat resistance, low coefficient of friction, and a wide range of applications. However, graphite is relatively brittle and has low strength. It is sensitive to shaft bending and local overload, so special attention should be paid. 导热油泵泵轴的左端装有叶轮,泵轴由滑动轴承支承,右端装有内磁转子。 The left end of the heat transfer oil pump pump shaft is equipped with an impeller , the pump shaft is supported by a sliding bearing , and the right end is equipped with an internal magnetic rotor. 托架联接泵和电机并保证内外磁转子的位置精度,拉丝机。 The bracket connects the pump and the motor and ensures the position accuracy of the inner and outer magnetic rotors , and the wire drawing machine.
热油泵一般选用耐腐蚀、高强度的工程塑料、刚玉陶瓷、不锈钢等作为制作材料，具有良好的耐腐蚀性能，并可以使被输送的介质免受污染 Hot oil pumps generally use corrosion-resistant, high-strength engineering plastics, corundum ceramics, stainless steel, etc. as production materials, which have good corrosion resistance and can protect the medium being transported from pollution.
导热油泵的结构特点导热油泵由联轴器和驱动电机,泵三部分组成。 Structural characteristics of heat transfer oil pump The heat transfer oil pump consists of a coupling, a drive motor and a pump. 如由超高分子量聚全氟乙丙烯和聚四氟乙烯组成的塑料合金，前者占重量比为0.1%一99.9% ，后者占重量比为99.9%一0.1% ，采用干粉共磨或干粉湿法共磨的共混方法制造。 For example, a plastic alloy composed of ultra-high molecular weight polyperfluoroethylene propylene and polytetrafluoroethylene. The former accounts for 0.1% to 99.9% by weight and the latter accounts for 99.9% to 0.1% by weight . Dry powder co-milling or dry powder wet Manufactured by blending method. 用热压或冷压烧结等方法加工成各种制品，克服了聚四氟乙烯冷流和易变形缺点，可延长使用寿命。 It can be processed into various products by hot pressing or cold pressing sintering, which overcomes the shortcomings of PTFE cold flow and easy deformation, and can prolong the service life.
