Hot oil pump is the ideal equipment for conveying high viscosity liquid. It adopts certain working principles and methods in production and production. It is produced and made in accordance with specific structure and form to ensure that it can play an important role and performance in the industry, and play more role and performance in the industry. There are still some problems in material selection, leakage and noise control. In particular, domestic Hot thermal oil circulating pump has a big gap with foreign products in efficiency, reliability and service life. Hot oil pump has excellent performance, reasonable structure, practical and reliable, suitable for conveying high temperature liquid without solid particles. The pump is a single-stage cantilever structure, divided into foot support and center support. The inlet of the pump is axial suction, and the entrance is vertical upward for the center. The driving motor of the pump is mounted on the same base through an elastic coupling. The whole unit does not need to add cooling system. It is mainly composed of shell, rotor, bearing, seal and other parts. It adopts packing seal structure, and has the function of high temperature resistant oil seal and gas auxiliary seal. The pump and the motor are connected by three jaw type elastic coupling. The pump from the design of the conservative structure of the hot oil pump, the use of natural cooling, reduce the volume of the pump, so that the structure is simple, save operating costs, safe and reliable. The hot oil pump bears the operation and transportation of the whole heat conduction oil. The elastic coupling should be checked regularly, the temperature rise of the motor bearing should be paid attention to, and the daily maintenance of the hot oil pump should be done well. The gears of hot oil pump commonly have straight teeth, helical teeth, helical teeth, and the tooth profile mainly has involute and circular arc types. Usually small hot oil pump mostly uses involute spur gear, hot oil pump often uses variable gear, melt pump conveying high viscosity, high pressure polymer melt mostly uses involute helical gear. Gear and shaft made into one, in order to reduce the flow resistance, improve the suction capacity of the pump, must be heated or heat preservation medium. Electric heating element is usually used to heat the viscous liquid evenly. If the temperature fluctuation is not large, the liquid is easy to degrade, it is recommended to use fluid heating, especially large displacement gear pump. Fluid heating and internal and external structure. The so-called built-in type refers to the internal design of hot jacket in the hot oil pump body or end cover, and the external type is connected with the hot jacket and the pump body by bolts. To the jacket into the steam, heat conduction oil, or cooling water, according to the specific situation of the medium. Its rigidity and reliability are higher than gear and shaft separately manufactured gear pump. The gear of hot oil pump abroad often adopts square structure, that is, the tooth width of the gear is equal to the diameter of the tooth top circle. The width of the teeth of the hot oil pump used in high pressure situations is less than the diameter of the top circle, which is to reduce the radial compression area of the gear and reduce the load of the gear and bearing.
