在研制40吨轮胎式集装箱龙门起重机过程中,考虑到某些大型港机在北方港口冬季使用的要求,保证柴油机冬季正常和顺利的启动,我们采用了YJ-Q14/2型冷却液加热器(图1)。40吨轮胎式集装箱龙门起重机(图2),采用上海柴油机厂生产的12V135D型柴油机做动力,其额定功率为240马力,额定转速为1500转/分,配用YJ-Q14/2型冷却液加热器。该加热器是河北省泊镇仪表厂制造的,其构造如图3所示。YJ-Q14/2型冷却液加热器的工作原理是:电动机3带动水泵1(有些不用水泵靠热对流循
In the process of developing a 40-ton tire-type container gantry crane, taking into account the requirements of certain large-scale port machines for use in northern ports during winter, and ensuring normal and smooth start-up of diesel engines in winter, we used a YJ-Q14/2 type coolant heater ( figure 1). The 40-ton tire type container gantry crane (Fig. 2) is powered by a 12V135D diesel engine produced by the Shanghai Diesel Engine Factory. Its rated power is 240 hp, and the rated speed is 1500 rpm. It is equipped with a YJ-Q14/2 coolant. Device. The heater is manufactured by Hebei Bozhen Instrument Factory and its structure is shown in Figure 3. The working principle of the YJ-Q14/2 coolant heater is that the motor 3 drives the pump 1 (some do not rely on heat convection
