东风 EQ 340型自卸汽车液压系统原为机—气—液联合控制。由于气路控制故障较多,且噪声大、可靠性差,我们对原系统进行了改进设计。新研制出的全液压系统经两万次台架试验和两年的装车试用,证明性能可靠。目前,我们已在东风 EQ 340、EQ 340C(EQ 341)、EQD 342等几种自卸车上全面采用。为了便于用户改装和使用、维修,现将该系统的工作
Dongfeng EQ 340 dump truck hydraulic system was originally machine - gas - liquid joint control. As the gas control more faults, and the noise, poor reliability, we improved the original system design. Newly developed hydraulic system after 20,000 times the bench test and two years of loading trial to prove reliable performance. At present, we have been in the Dongfeng EQ 340, EQ 340C (EQ 341), EQD 342 and several other types of dump truck fully adopted. In order to facilitate the user to modify and use, repair, the system will now work
