Excavator, explosion-proof valve for oil cylinder, hydraulic system of explosion-proof valve for oil cylinder and implementation method of explosion-proof valve for oil cylinder
The invention discloses an excavator, an explosion-proof valve for an oil cylinder, a hydraulic system of the explosion-proof valve for the oil cylinder and an implementation method of the explosion-proof valve for the oil cylinder. The hydraulic system of the explosion-proof valve for the oil cylinder comprises a pilot pump, a main valve, a controller, a sensor, a pilot handle, an oil cylinder and the explosion-proof valve; The explosion-proof valve integrates a proportional solenoid valve based on an original structure. The pilot pump, the main valve, the pilot handle, the explosion-proof valve and the oil cylinder are connected through hydraulic pipelines; and the proportional solenoid valve, the controller and the sensor are connected through wires; an input port and an output port areformed in the controller, the input port is connected with the sensor, the output port is connected with the proportional solenoid valve, and the hydraulic control is changed to electric control. Theproblems of crawling and slow response of the explosion-proof valve oil cylinder when the hydraulic oil temperature is low are solved; and the stability and controllability of the operation are improved.
本发明公开了一种挖掘机、油缸用防爆阀及其液压系统和实现方法，油缸用防爆阀液压系统包括先导泵、主阀、控制器、传感器、先导手柄、油缸和防爆阀；其中，防爆阀是在原有结构基础上集成比例电磁阀，所述先导泵、主阀、先导手柄、防爆阀以及油缸通过液压管路连接；所述比例电磁阀、控制器、传感器通过电线连接；所述控制器具有一个输入端口和一个输出端口，输入端口与传感器连接，输出端口与比例电磁阀连接，将液压控制变为电控。本发明解决防爆阀油缸在液压油温较低时，出现爬行、反应迟缓等问题；提高了操作的平稳性、可控性。
