Hot oil pump impeller is introduced

We often see on hot oil pump impeller balance hole, but I don’t know balance hole the size of the number is based on what to order?Impeller to distance to balance hole on the back of the role of the influential? Hot oil pump impeller balance hole is primarily balance of axial force, which is associated with sealing ring gap.We know that heat pump axial force is derived from the differential pressure of impeller front and back cover.Because the former carries oil inlet, botou haina is a complete plane, the area of different pressure is generated by the pressure differential.If the force is not big, the bearing can withstand, could be solved through bearing.When multi-stage pump, or impeller is too large, the axial force is not the bearing, we must take other corresponding axial force balancing mechanism.Such as the balance disc, balancing drum, balance hole, etc.Balance hole has simple structure, convenient processing is a commonly used equilibrium structure.We know that the pressure difference between before and after impeller cover plate, the main influence factor is the front cover for the oil inlet hole, the area is small a piece, so the HouGaiBan must have a sealed chamber, its area is roughly the same as the inlet area (in order to convenient manufacturing, before and after taking ring is the same, you can save a parts).Thus HouGaiBan the balance holes should be sealed room, from the hot oil pump impeller inlet direction, balance hole should be set in the hot oil pump impeller import parts (favorable) liquid.In order to make the machine to receive strength evenly in the impeller, balance hole should be in the same uniform in diameter.Balance hole size, because the flow is mainly the action of the balance holes static pressure, so the balance hole diameter is not big, usually 3 to 5 mm.

China Hot Oil Pump History

Hot oil pump start from 2001, after 5 years of development, China hot oil pump industry started from its early into the growth period.Since the 1970 s, hot oil pump industry has entered a golden age, the study of hot oil pump work in all countries of the world attaches great importance to, such as the international energy agency and the European Union, have made a big hot oil pump development plans, hot oil pump new technology emerge in endlessly, the purpose of the hot oil pump is also in constant development, widely used in air conditioning and industrial areas, in terms of energy saving and environment protection plays a significant role.Before the international energy agency set up international heat pump center, the project set up hot oil pump, to countries in the world to promote coordination of heat pump technology application and development.The United States, Canada, Sweden, Germany, Japan, Korea and other countries have a special government official guidance, promote social application of heat pump technology. China hot oil pump industry rapid development, the theory of hot oil pump originated in the early 19th century French scientists saadi.Botou Haina Pump Industry CO.,Ltd manufacture hot oil pump,Cano (Sadikarnot), cano in 1824 for the first time in this paper puts forward that “carnot cycle” theory, 30 years later, a British scientist kelvin (l. elvin) in early 1850, put forward: frozen device can be used for heating, after a lot of work on many of the scientists and engineers to heat pump, the last 80 years.On the one hand, thanks to the nervous energy heat pump energy saving advantage more and more obvious, on the other hand, with the addition of various power industry technology innovation.

Hot Oil Pump

Overview: Hot oil pump is a single-stage centrifugal pump, applicable temperature: less than 370 degrees Celsius. Flow 1-500 cubic meters per hour.Manufacturer and suppliers is china Botou Haina Pump Industry CO.,Ltd. Structure: Support of hot oil pump adopts the structure of the double end ball bearing supporting, front-end used lubricating oil, the back end lubricated by grease, with an oil conduit in the middle, to observe the conditions of sealing and recovery of heat conduction oil. Assemble: 1. Install bearing respectively on the bearing box and housings. 2. The circle will be felt in a bearing end cover a, c, and bearing box. 3. The bearing end cover b, c on the bearing seat and bolts. 4. Will pack good bearing wear on the shaft bearing box, round nut on the screw, and the bearing end cover a fastening on the bearing box. 5. The axial load bearing, bolted, screw the adjusting screw, and the bearing installed on the bearing seat, will block water trap at lower bearing appropriate location. 6. The connecting tube fixed on the bearing seat, and pump cover on the connecting tube bottoms, mount and tighten the impeller, at the bottom of the shaft in turn mount pump devices for cover, and bolted, the adjustment screw impeller with bearing box with clearance between the front cover, (control within 1 ~ 1.5 mm) set with nut, bolt fastening. 7. Bolt, motor bearing is installed on the bearing seat at the top of the shaft coupling components, and the motor shaft coupling with fastening screw fastening on the motor shaft, the motor installed on the motor bearing, and bolt, nut fastening. 8. From the pump export order to asbestos mat, bend, the liquid components of produced liquid, and fixed bearing seat. Hot oil pump operation specification This standard specifies the operation staff must abide by the safety rules of heat conduction oil pump (2) of this standard is only Yu Zhongrong environmental equipment workshop heat conduction oil pump station 2, before the start of preparation 1) check the oil pump machine lubricating oil is in the calibration of the center line, avoid too high or too low; 2) check the pump parts with or without fixed connection screw loose coupling two shaft position is concentric, end clearance fits (3-5 mm); 3) turning 3-5 circle whether rotating flexible, the presence of resistance and noise; 4) the transmission of heatRead More…
