Abstract

The invention discloses a hydraulic oil cylinder loading test hydraulic system which includes an oil tank body, a test system, a power system and a tested oil cylinder. The test system includes an H-type functional electromagnetic reversing valve, a plug-in mounting type left electromagnetic ball valve connected with a port A, a plug-in mounting type right electromagnetic ball valve connected witha port B, two manual ball valves and two pressure gauges. The power system includes a liquid filling unit and a loading unit. The upper part of the liquid filling unit is provided with a pressure switch and a one-way valve in turn, is connected to a port P of the electromagnetic reversing valve, and is in parallel connection with a low pressure overflow valve. The loading unit is connected to theport P of the electromagnetic reversing valve through the check valve, converges with the liquid filling unit, and is in parallel connection with a high pressure overflow valve. The installed power of the system is reduced by double-pump converging configuration, the pressure switch is adopted to detect loading pressure, the operation is convenient and reliable, and no energy waste is caused.

Description

technical field [0001] A hydraulic oil cylinder loading test hydraulic system belongs to the field of hydraulic pressure and electric power, and relates to a hydraulic system. Background technique [0002] In recent years, my country has carried out large-scale urban municipal engineering construction, especially subway construction. Due to the influence of urban environmental factors such as construction sites and road traffic, traditional construction methods are difficult to implement. Therefore, tunnels with less environmental impact are selected Construction method, shield construction method. [0003] The shield tunneling machine is propelled forward by the thrust of the hydraulic cylinder. When working underground, it will receive various resistances from the soil layer during the excavation process. In order to ensure the normal excavation of the shield machine, the resistance must be overcome by the propulsion system. The propulsion power transmission and control sy...
