Electro-hydraulic servo hydraulic system:

       Electro-hydraulic servo hydraulic system includes servo hydraulic system for static test and servo hydraulic system for dynamic test.

       The servo hydraulic system for the static test adopts an integrated system, that is, the electric control cabinet and the oil source are integrated as a whole, and it is equipped with a self-developed electric control cabinet that can remotely control the start and stop of the oil source and high and low pressure dual control modes, imported brand low-noise quantitative high-pressure gears Pumps, domestic top brands of hydraulic valves, hydraulic accessories and cooling systems, self-developed high and low pressure dual control valve groups and multi-channel static oil separators, rated pressure 25MPa, under the working condition of maintaining pressure for no less than 8 hours, Ensure that the oil temperature of the hydraulic system is within the normal working range.

       The dynamic test servo hydraulic system is an intelligent servo hydraulic system, equipped with an electric control cabinet with a self-developed intelligent control system with a touch screen, imported brand flow control high-pressure plunger pumps, domestic top brand hydraulic valves and hydraulic accessories, self-developed high Low-pressure dual-control valve group and multi-channel dynamic oil separator, rated pressure 21MPa. The oil source is equipped with an independent circulating cooling system and an oil temperature and liquid level monitoring system, which implements closed-loop control. When the oil temperature is higher than a certain set temperature, the cooling system is turned on, and when the oil temperature drops to another set temperature, the cooling system is stopped. , which can ensure that the oil temperature will not be too high; when the hydraulic oil in the oil tank is lower than a certain liquid level (set value) due to normal loss, the system will send out an alarm, the oil pump will stop running, and the tester will be prompted to add oil to the oil tank. Hydraulic oil, to ensure that the oil pump is not damaged due to lack of lubrication; the flow control oil pump can effectively adapt to the flow required by the system, and the energy saving effect is very obvious, which can ensure that the hydraulic system remains in working condition for a long time.
