Hydraulic system液压系统
Single open hydraulic loops (pumping hydraulic circuit is independent of distributing hydraulic circuit) with one pumps, makes the whole hydraulic system much simpler. The reliability of the whole system is also much higher as well as the components’ life is prolonged greatly. This is convenient for judging and removing trouble.
采用单泵、单回路开式液压系统，主泵送油路和S阀摆动油路相互独立，使系统简单，元件寿命延长，可靠性更高，并便于故障判断和排除。
Large valve changing direction, makes the main pumping loop quick response, small leakage, good stability, high reliability and high resist contaminative capability.
主泵送油路采用大通径阀换向，响应快,内泄漏小,稳定性好,可靠性高,耐污染能力高。
Hydraulic system has safe relief protection, at the same time, when the system pressure is over; the main oil pump cutting device makes itself be protected reliably.
泵送液压系统具有安-全溢流保护，同时，主泵还具备系统超压时，油泵压力自动切断截流装置，使主泵获得多级可靠保护。
Cone sealing of all pipes make the pipe joints seal reliably.
所有管路均采用锥面密封，管路接头密封可靠。
Adopt emulsification technology of initiative and passivity recovery integration.
采用了主动防御和被动防御相结合的综合防乳化技术。
