1.IntroductionHybridDriveProductsSVPDSVPSVP –Servo Variable-speed Pump 【each pump 25cc 250cc】DSVP--Double Servo Variable-speed Pump 【each pump 6cc 71cc】SVP system is formed by pressure and flow double closed-loop control, and can only rotate inone direction. Selector valve controls the direction. SVP is normally used for power supply;DSVP system is formed by position, pressure and flow triple closed-loop control. It can rotatein both direction. DSVP is suitable for machines which require high precision and positioncontrol.

2. Why electrical hydraulic drive high pressure throttle overflow lossHydraulic process is generally divided into several stages, each stage requires differentpressure and flow. Motors’ rated power are determined by the highest pressure and flowrequirements. Motor runs at a constant speed to provide a constant flow (some variablepump has variable flow) In the most time of working time, the flow & pressure demandof equipment is less than the rated flow and maximum pressure. In traditional hydraulicstructure, extra hydraulic oil which is brought by constant motor speed will go back intooil tank through overflow valve, and does not go through the cylinder. In this processwhich is called high-pressure throttling, usually about 30% to 70% oil will be wasted.Oil tank3 phase induction motorCylinder workThrottle to oil tank
2. Why electrical hydraulic drive Low efficiency of 3 phases induction motorThe efficiency and power factor of traditional pump motor which is 3 phases inductionasynchronous motor is normally 10% lower than permanent magnet synchronous servomotor. During standby stage, the efficiency and power factor is much lower.
2. Why electrical hydraulic drive Power consumption of cooling systemBecause of the high-pressure throttling, the temperature rising of hydraulic oil can cause oildilution, oil tube softening, oil leaking and many other problems. So, many hydraulic systemsrequire extra cooling system. Comparing with traditional hydraulic system, there will be no coolingsystem needed. 100% power consumption of cooling system will be saved. Rated power and power distribution loss1、The overload (normally 1.5 times) of 3 phases induction asynchronous motor is lower than theoverload (more than 2 times) of permanent magnet synchronous servo motor.2、 3 phases induction asynchronous motor requires more complicated power distribution system,because its high starting current, and starting mode (star connection). Permanent magnetsynchronous servo motor only requires 2 times current, even when it is in 2 times torque output.3、 Duplex pump (high & low pressure switching) can be supported by servo pump system. Ratedpower is much lower when pressure maintaining stage is finished by small pump

Exo isomer was eluted first closely followed by the endo isomer. Exo isomer exhibited tailing and sometimes continued to elute even after elution of the endo isomer was completed. Thus, the endo isomer was usually contaminated by the exo isomer. Usually, a repeated chromatography was needed to obtain a pure endo isomer. Scaled up experimental .

The integration ratio is about 3:1 for 2.5 ppm vs. 2.3 ppm in the final spectrum. One arrives at this conclusion from noting that there are four possible stereoisomers for the final product, (exo,exo), (exo,endo), (endo,exo), and (endo,endo), where the descriptors refer to the orientation of the methyl
