1985年第4期《内燃机车》刊登了乌鲁木齐机务段解决东风及东风_3型机车的风泵在低手柄不打风的方法,这个方法很好。为解决由于风泵背压大而造成的低手柄不打风问题,我们还有更简单有效的方法。利用电空阀(在不使用电阻制动的机车上,该电空阀空着,并离风泵很近)和一个行程开关(将其装在油路控制阀旁),并在风泵 1985 fourth issue of “diesel locomotive” published Urumqi locomotive section to solve the Dongfeng and Dongfeng _3 locomotive wind pump in the low handle does not hit the wind method, this method is very good. In order to solve the problem that the low handle does not hit the wind due to the large back pressure of the air pump, we have a more simple and effective method. Using an electropneumatic valve (on a locomotive that does not use a resistor to brake it, the electropneumatic valve is empty and close to the pump) and a travel switch (located next to the circuit control valve)
