Abstract

The invention discloses a hydraulic cylinder loading detecting device which comprises a first oil pump, a second oil pump, a pressurizing cylinder, a reversing valve, a first connector used for being connected with a first hydraulic cylinder and a second connector used for being connected with a second hydraulic cylinder. A first cavity of the pressurizing cylinder is connected with the first oil pump which provides oil for the pressurizing cylinder through the reversing valve and is connected with the second connector which provides oil for the pressurizing cylinder at the same time. A second cavity of the pressurizing cylinder is connected with the first connector and is used for providing oil for the first connector. The second connector is connected with the second oil pump which provides oil for the second connector. The pressurizing cylinder can output driving pressure oil with pressure higher than oil source pressure, the problem that an oil source is at a high-pressure working state can be avoided, and oil source service life is prolonged. In addition, energy recycling and reusing can be achieved, system installing power is lowered, system heating is low, and cooling power can be saved.

Description

technical field [0001] The invention mainly relates to the technical field of hydraulic cylinder testing and detection, in particular to a hydraulic cylinder loading detection device. Background technique [0002] The hydraulic cylinder is the actuator of the hydraulic system, which is used to drive various working mechanisms. It is a key component in mechanical products, and its performance greatly affects the quality of the whole machine. One of the effective means to verify the performance of hydraulic cylinders is to carry out loading tests according to relevant standards on a special test bench. [0003] According to the national standard GB / T15622-2005, the most important item in the type test is to carry out 200,000 full-stroke load tests, which means that a hydraulic system that can work under high pressure for a long time is required and consumes a lot of electric energy. The test bench in the prior art usually uses an oil pump to directly supply oil to the hydraul...
