Structure and performance of the heat transfer oil pump

Thermal conductivity oil pump for the petrochemical industry process does not contain solid particles and fibers, the temperature is not higher than 250 ℃, the viscosity of 5 ~ 1500cst a certain lubricity of the fluid. For corrosive or high hygiene requirements of the occasion can use stainless steel pump. Conductive oil pump in a certain environment and industry summary has an important role and performance, the use of advanced technology for the design and production of gear pump for the circular arc gear, and Shanghai Jiaotong University jointly designed and developed with the international advanced level New product Gear meshing for a little contact with the rolling contact, no flow pulsation, smooth operation, small vibration, low noise. The widely used in shipbuilding, electric power, metallurgy, grain and oil, food, petroleum, chemical and other industries. Heat transfer oil pump has a certain structure and performance, in the structural design has a unique innovation process, the so-called vice impeller hydrodynamic seal is the high-viscosity pump impeller rear cover near the back of the coaxial installation opposite an opposite direction of an open impeller. When the heat conducting oil pump is working, the auxiliary impeller rotates along with the spindle of the high viscosity pump, and the liquid in the auxiliary impeller will also rotate together. The rotating liquid will generate an outward centrifugal force which, on the one hand, withstands the liquid flowing to the mechanical seal, Reduced pressure on the mechanical seal. On the other hand prevent the solid particles in the medium from entering the friction pair of the mechanical seal, reduce the abrasion of the mechanical seal and prolong the service life of the mechanical seal. Vice impeller in addition to play a sealing role, but also can play a role in reducing the axial force in the submersible heat-conducting oil pump axial force mainly by the liquid pressure on the impeller pressure and the entire rotating part of the composition of gravity, The two forces are acting in the same direction. The resultant force is formed by the sum of two forces. It can be seen that under the same performance parameters, the axial force of the submersible heat-conducting oil pump is larger than that of the horizontal heat-conducting oil pump, which is more difficult to balance than the vertical high-viscosity pump. Therefore, in the submarine heat-conducting oil pump, the bearing easy to damage the reason is also a great relationship with the axial force. If the vice impeller is installed, the direction of liquid pressure exerted on the impeller is opposite to the resultant force of the above two forces, so that it can offset part of the axial force and play the role of prolonging the life of the high-viscosity pump bearing. However, there is also a disadvantage of using an aero-impeller seal system that consumes about 3% of the energy on the aero-impeller, but as long as the design is reasonable, this loss can be reduced to a minimum. Conductive oil pump in use to maintain good performance advantages, to ensure maximum efficiency, in the substantial role of practice to achieve a good price, get the favor and use of different consumers.
