131复式风泵经过二十多年的运用,虽然有关部门在运用、保养和检修等环节上进行了多方面的努力,但复式风泵在运用过程中的偷停故障始终未能根除。据铁道部机务局1980年统计,由风泵故障造成的机破事故占机破事故总数的20.6％,其中又以偷停故障为最多。由于装有131复式风泵的机车,一般只装有一个风浆,一旦风泵失灵,机车或列车即处于失控状态,严重危及行车安全。因此,风泵问题的根本解决,是机车检修工作中的迫切问题。一、主阀与变向阀的受力分析复式风泵的不停运转,完全受控于变向阀与主阀的协调动作。因此,要解决复式风
After more than 20 years of application, although the related departments have made various efforts in the aspects of operation, maintenance and overhaul, the stolen fault of the double-type air pump has not been eradicated during the operation. According to the 1980 statistics of the Bureau of Railway Administration, 20.6% of the total number of machine-broken accidents were caused by wind pump failures, among which the most were stolen faults. As a result of the installation of a 131-compound wind-driven locomotive, there is usually only one wind slurry. Once the wind-driven pump fails, the locomotive or train is out of control, seriously endangering traffic safety. Therefore, the fundamental solution to the problem of the wind pump is an urgent problem in locomotive maintenance work. First, the main valve and variable valve force analysis Duplex pump non-stop operation, fully controlled by the main valve to change the coordination of the valve action. Therefore, to solve the complex style
