Qianjin steam locomotive is the first high-power trunk freight locomotive designed and manufactured by ourselves in China, code QJ (once called Heping, code HP; Anti-imperialist type, code name FD). 1956 is designed and manufactured by Dalian factory. From 1958 to 196 1, Datong, Shenyang, Changchun, Tangshan, Mudanjiang and other factories have manufactured 42 locomotives (9 of which are old-fashioned six-axle coal water trucks and the rest are four-axle coal water trucks). The structural characteristics of the forward steam locomotive are as follows: (1) The boiler is of all-electric welding structure, with a fire box inside and no combustion chamber; (2) Cast steel cylinder, transfer steam valve and I-shaped sliding crosshead are used, and rolling bearings are used as main moving rods; (3) The wedge iron automatic adjusting device is adopted to install the attached weighting machine; (4) The underframe and water tank of the coal waterwheel are fully welded and equipped with coal feeder. Two kinds of coal waterwheels, four-axis sliding bearing and six-axis rolling bearing, are designed.
1964 Datong factory became a factory specializing in manufacturing steam locomotives, and the boiler part of the car was redesigned. With the increase of combustion chamber, the height of boiler center is reduced by 80mm, the length of flue pipe is shortened to 5350mm, the ventilation device of flue box is greatly improved, and the performance is also improved. The test shows that when the calculated steam supply is 75 kg/(m2 h) and the speed is 70kmn/h, the maximum power around the wheel can reach 2 192kW, and the total efficiency of the locomotive can reach 8.42%. In order to give full play to the efficiency of boiler and improve the working conditions of flight attendants, stoker, coal pusher and air blower are adopted. The locomotives used in cold areas adopt sealed cab.
