Lab vacuum short path distillation system is similar as Rotary Evaporator Rotovap for vacuum distillation and crystallization process .
Lab short path distillation kit including magnetic stirrer heating mantle with round bottom boiling or evaporation flask with condenser head with cold trap
Lab heating mantle with excellent properity for high temperature and can reach up 300c so the distillation purity is much better than rotary evaporator water bath machine
Zhongyi kori factory has 2l 5l 10l 20l short path distillation glassware unit
We also can Customized Dual Short Path Distillation kit with dual condenser and dual collection flask with dual cold trap to enlarge distillation yield
From the data of 2012, the total output of planetary reducers accounts for the main share of the total output of the reducer, not only in the reducer industry, but also from the overall situation of China's regional development, the coastal region has its unique geographical advantage. As well as the long-term development of the economy, the strength of many industries in which it is located is far ahead of the mainland.
In 2013, the domestic reducer industry still faces enormous challenges. Although some countries attach more importance to the entire equipment manufacturing industry and support, the market demand is not prosperous. On the other hand, the financial pressure of small and medium-sized enterprises is generally large. Under this circumstance, the country's tightening of monetary policy will inevitably increase the difficulties of small and medium-sized enterprises, reduce the amount of technology research and development funds, and increase the gap with imported products. It is at this stage that companies may wish to improve their development model, increase their marketing channels, broaden their market demand, and respond to the reshuffle of the industry with a flexible strategic vision to meet the “spring†after the “severe winterâ€.
For the future development of planetary reducers, there are basically the following aspects:
1, hard tooth surface, high precision. At present, planetary reducers are generally subjected to chemical heat treatment such as carburizing and nitriding in the manufacturing process, and the manufacturing precision has reached 6 or more.
2, high speed, high power. With the development of planetary rotation technology, the existing high-speed involute planetary gear transmission has reached 2000KW, and the output torque has reached 4500KNm. It has broken through the development bottleneck of high planetary gear transmission for a long time, but the transmission ratio is not large.
3. Variety of varieties. At present, there are more than 50 planetary gear rotation series in the world, which has evolved various forms of reducer products.
4. Realize electric integration. In the planetary gear rotating device, a micro-transmission device that transmits power is required - the micro planetary gear reducer works in conjunction with the micro planetary gear reducer with its own power drive, that is, the micro-machine needs to be decelerated by the micro-motor and the micro-planetary gear. The unit combines a compact gear transmission with both drive and reduction drives. The electromechanical integration is realized, and the motor and the planetary reducer are combined to form a low-speed motor, so that the output shaft of the assembly is directly connected to the working machine, and the shift adjustment is effectively performed.
