5 points to note when reducing the loss of hydraulic universal testing machine

Universal testing machineThere are electronic universal testing machines and hydraulic universal testing machines. No matter which type of instrument is used, it will cause losses to the machine. The following are a few key points proposed by Jinan Hengsi Shanda Instrument Co., Ltd.:

(1) Designed using resonance principle

(2) Use a dual pump oil supply system

(3) Adopt AC hydraulic technology

(4) Use pressure adaptive oil source

(5) Configure the accumulator

Many instrument companies are designing nowHydraulic universal testing machineAt the time, designers often focus on the accuracy, function, reliability and other indicators of the test machine, and the energy consumption of the test machine is less considered, so the designed test machine is less efficient and causes waste of energy. Especially for test machines that use hydraulic transmission, most hydraulic systems use throttling speed regulation, which causes the system to heat up due to inevitable throttling or overflow losses. In order to maintain the ideal oil temperature, cooling measures have to be taken, which further aggravates the reactive power consumption of energy. This problem is not particularly obvious in static test machines, but it is particularly prominent for dynamic fatigue test machines and electro-hydraulic servo dynamic and static universal test machines. Therefore, the efficiency issues of the test machine and the concept of green design have gradually gained people's understanding and attention. The following solutions are some energy-saving measures that have been used in the development and development of the test machine. Practice has proved that they have all played a good energy-saving effect to varying degrees.
