LDHBTS80-13-129R履帶柴油泵采用雙泵、雙回路開式液壓系統，主泵送油路和S閥擺動油路相互獨立，使系統簡單，元件壽命延長，可靠性更高，并便于故障判斷和排除。
2.1 Hydraulic system液壓系統
● Double open hydraulic loops (pumping hydraulic circuit is independent of distributing hydraulic circuit) with two 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 judgeing and removing trouble.
采用雙泵、雙回路開式液壓系統，主泵送油路和S閥擺動油路相互獨立，使系統簡單，元件壽命延長，可靠性更高，并便于故障判斷和排除。
● 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徑閥換向，響應快,內泄漏小,穩定性好,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.
泵送液壓系統具有安全溢流保護，同時，主泵還具備系統超壓時，油泵壓力自動切斷截流裝置，使主泵獲得多級可靠保護。
● Distributing hydraulic circuit adopts constant pressure pump, which can provide strong distributing pressure and economic energy control.
擺動油路采用齒輪泵供油，擺動力大又具備節能功能。
● Cone sealing of all pipes make the pipe joints seal reliably.
所有管路均采用錐面密封，管路接頭密封可靠。
● The high-low pressure switch adopting cartridge valve of reduces the trouble of dismantling and installing the oil pipe.
采用高低壓轉換，免去拆、裝油管的麻煩。
● Adopt emulsification technology of initiative and passivity recovery integration.
采用了主動防御和被動防御相結合的綜合防乳化技術。
2.2 Electric control system電控系統
● Compared with domestic product, the electric control system is simplest, the element quantity is fewest and its reliability is highest.
與國內同類產品比較，電控系統最簡單，采用元器件數量最少，可靠性最高。
● The wire remote equipment is convenient for operation far away.
配有有線遙控裝置，方便遠距離操作。
● Adopting proximity switch in hydraulic cylinder can realize changing direction with non-touch, which ensures that the direction can be changed reliably.
采用油缸內接近開關非接觸換向，確保換向可靠。
2.3Mechanical system機械系統
● The design of hopper and S valve and so on adopt Ｉ－DEAS software to caculate, the hopper and S valve have good rigidity to avoid the phenomenon of hopper distortion and S valve breakage.
料斗、S閥等關鍵受力元件的設計，采用Ｉ－DEAS軟件對其受力狀態、結構剛度、應力集中狀況進行了細分網格的有限元計算，設計出的料斗、S閥結構剛度好、工藝性佳，避免了同類產品高層輸送時料斗變形及S閥斷軸現象。
● The agitator have unique form, which separates the hydraulic motor from agitator bearing pedestal.At the same time, adopting large displacement motor ensures that the agitator moment is big enough.
攪拌機構采用獨特的結構形式，將液壓馬達與攪拌軸承座完全隔離，即使攪拌密封磨損漏漿，也不至于影響液壓馬達。同時，采用大排量馬達，確保攪拌力矩足夠大，即使料況差的情況下也能正常攪拌不被卡死。
● Make sure the pumping is good and decline the phenomenon of pipe jam, the spectacles wear plate and cutting ring should be useed in lower abrasion. Xinsai’s spectacles wear plate and cutting ring use high wear material, making the components’ life prolonged greatly.
混凝土泵的眼睛板，切割環應該在低磨損下使用，才能夠確實保證良好的泵送狀態，降低堵管現象的發生。本公司采用高耐磨硬質合金材料眼睛板、切割環。眼鏡板、切割環等易損件經過不斷的技術攻關，使用壽命更長，較好泵送狀態時，眼鏡板最高壽命最長可達到3萬方以上。
2.4Lubrication system潤滑系統
The hydraulic circuit will take high oil into double distributor,and then the lubricating part can obtain hydraulic oil.It ensures the lubrication of the concrete cylinder’s piston and other parts and prolongs the life of piston and other sealings.
換向時液壓油路將高壓油輸入雙線分配器。伴隨混凝土缸活塞的每個沖程運動，各需要的潤滑部位都可以從雙線分配器中得到一滴液壓油。它確保了混凝土缸活塞和各需要的潤滑部位的必要的潤滑，延長了混凝土活塞及其他密封件的壽命。
2.5Cooling system冷卻系統
The radiator equipment makes the working oil temperature of hydraulic system below 70℃ and makes the machine in normal status.
采用強制風冷大散熱器裝置，確保液壓系統的工作油溫控制在70℃以下，從而保障主機液壓系統處于正常的工作狀態。
