LQRY型导热油泵在我国载热体加热系统中得到了广泛的使用，已经进入石油、化工、橡胶、塑料、制药、纺织、印染、筑路、食品等各个工业领域，主要用于输送不含固体颗粒的弱腐蚀性高温液体，使用温度≤370℃，是一种理想的热油循环泵。

LQRY Heat Condition Oil Pumps is widely applied in the heating system with heat transfer media in China for such industrial fields as petroleum, chemical industry, rubber, plastics, pharmacy, textiles, printing and dyeing, road construction and food. It is an ideal circulating pump for hot oil and mainly used for transferring weak-corrosion and high-temperature liquid without containing solid grains, whose working temperature is ≦370℃.

结构特点Structural Features

LQRY型导热油泵是本单位消化吸收国外油泵的基础上研制的第二代产品、基本结构形式为单级单吸悬臂式脚支撑结构、泵的进口为轴向吸入，出口为中心垂直向上，和电机同装于底座上。

LQRY型导热油泵的支撑采用了双端球轴承支撑的结构形式，前端采用润滑油润滑、后端采用润滑脂润滑，中间有一导油管，用以随时观察密封情况和回收导热油。

LQRY型导热油泵：（1）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。（2）采用第三代聚四氟乙烯（简称PTFE）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。

LQRY Heat Conduction Oil Pumps is the second generation of our product developed on the basis of digesting foreign oil pumps. Its basic structure is single-stage single-suction cantilever leg support, which has an axial suction inlet and a centrally vertical outlet. It is mounted on the base along with the engine.

LQRY Heat Conduction Oil Pumps adopts a double-end ball bearing support with the front end using the lubricating oil while the back end using the grease as the lubricant, and an oil conduit lying in between for always keeping an eye on the sealing and the recovery of conduction oil.

It adopts the self-heating and abstraction of heat structure instead of the traditional water cooling structure, thus featured by a simple and space-effective，fewer operating costs, good performance and reliable operation.

LQRY Heat Conduction Oil Pumps(1)combines the packing seal and the mechanical seal; the former has a good adaptability for the thermal state due to using packing with resistance to high temperature while the latter ensures the seal performance under high temperature as it adopts the hard alloy with strong mechanical strength and wear resistance;(2)adopts the third generation of PTFE for the lip seal, thus getting great performance in the seal performance, 25 times the reliability of the rubber seal, and extremely strong resistance to corrosion.
