Shantui bulldozer-te tana steering valve-te background leh application scenario tlangpui Shantui bulldozer-a accessory system, steering valve, steering system-a key component angin, machine-a steering control performance pumpuiah hmun pawimawh tak a chang a ni. Tunah hian "steering valve assembly (B)"-a parameter bikte chu zawn result-ah direct-a sawi ni lo mah se, Shantui SD series bulldozers-te steering system design zawng zawng leh a kaihhnawih accessory information te chu steering system hnathawh dan thlirna atanga steering valve hman dan hriatthiamna atana reference pe turin a inzawm khawm thei a, chutiang bawkin steering system of mainstream models shari leh steering system of mainstream model SD52-5 hian modular structure design a hmang a, steering valve hi core control component a ni. Bulldozer operation scenario hrang hrangah hman a ni nasa hle a, chungte chu Earthwork Engineering, Mining, leh Infrastructure sak te a ni a, hnathawh dan tur (complex working conditions) hnuaia hmanrua him taka khalh theihna tur a ni
Application scenario leh performance parameter te .
1. A hman dan tlangpui .
Bulldozer Steering Control: Steering cylinder chu direct-in khalh la, angle lian tak steering ± 30℃emaw a aia tam emaw a awm theih nan, construction site tawi emaw, complex terrain emaw atan a tha.
Low Speed Heavy-Duty hmanrua, loader, tractor, etc. BHR series steering gear hian 1000m 3/r thlenga displacement leh steering torque 1.6-2.8N · m optimized structural design hmangin a tuar thei a ni.
Emergency Manual Steering: Model thenkhat (BZZ2 ang chi) engine a chhiat chuan manual operation an support a, mechanical linkage hmanga basic steering function an vawng reng bawk.
2. Hnathawh tur pawimawh tak tak te .
Pressure leh Flow: Blv{{0}ZXFZ{{1}SY-KTC steering valve group hian working pressure sang ber 21mpa leh flow rate 120L/min a nei a, pressure sang leh flow lian tak mamawh a tlin a ni.
Response Speed: BHR5 load sensing steering gear hian priority valve nen inzawmin millisecond level flow distribution a thlen thei a, steering sensitivity a ti tha thei bawk.
Rinnawmna: Balanced valve core leh wear-resistant materials (silicon nitride ceramics ang chi) hman hian valve assembly dam chhung chu darkar 5000 chuang a ti rei thei a ni.
Technical characteristics leh industry kalphung .
Intelligent upgrade .
Kum 2025 khan steering valve thar B B B B B B B bus control leh displacement sensor (Hengli HSQD series ang chi) te chu a inzawm khawm a, chu chuan valve core position leh system pressure chu real time-in a enfiah thei a, fault self diagnosis leh remote monitoring a nei thei a ni. Entirnan, closed-Loop feedback technology hmangin steering accuracy error chu ± 0.5℃chhungin control theih a ni.
Energy humhimna tur design .
Load sensitive technology (BHR5 type ang chi) hman a nih chuan hydraulic flow chu steering load a zirin automatic-in a inthlak a, traditional valve group nena khaikhin chuan 15% -20% energy a humhim thei a ni. Model thenkhat chuan "floating mode" an support bawk a, hei hian bulldozer chu a terrain nen a inmil nghal vek a, energy hman a tihtlem phah bawk.
Materials lama thil thar chhuah .
Ceramic valve core (alumina ceramics ang chi) hman hian corrosion resistance leh wear resistance nasa takin a ti tha a, acidic soil emaw high dust environment-ah chuan service life chu a let thum aia tam a ti rei bawk. Chutih rual chuan bio based sealing materials hman hian EU environment standards a zawm a, carbon emission 10% a tihtlem bawk. Plus series bulldozers hi control system-ah optimized a ni a, variable speed steering control chu driver veilam sir a handle pakhat dah a ni.
Integrated Control Design hian steering valve control accuracy-ah demand sang zawk a dah a, handle operation-ah dik taka chhan let a ngai a, steering action mumal leh tha tak neih a ngai bawk. Chu bakah, Plus series bulldozer te hian seamless snakeskin tubes leh T- vehicle wiring harness atan splitters ang chi an hmang bawk. Seamless snakeskin tubes hian strength sang tak leh sealing tha tak a nei a, hei hian lirthei wiring harness a humhim tha thei a, steering valve control circuit pawh a huam tel a, circuit fault avanga steering valve hloh theihna a tihziaawm bakah steering system stability a ti tha thei bawk.
