储能器的作用是在发动机突然熄火、制动泵失灵或其输出的油液压力不足时,向制动器提供足够的油压,以使叉车驾驶员能在紧急状态下实现制动停车。本文以某型号内燃叉车为例,阐述储能器报警装置工作原理及故障排查方法。1.工作原理储能器报警装置结构如附图所示,其主要由单向阀1、油室2、储能弹簧3、低压报警开关4和安全阀5等组成。制动泵输出的压力油经单向阀1进入油室2,将储能弹簧3压缩,从而将油液的压力能转化为储能弹簧3被压缩的势能。单向阀1的作用是防止油液从压力油的入口倒流。低压报警开关4为隔膜式常闭开关,当油室2中的油压高于3.9M Pa时,该低压报警开关断开,将报
The function of the accumulator is to provide sufficient oil pressure to the brakes when the engine suddenly stalls, the brake pump fails or the output oil pressure is insufficient, so that the forklift driver can brake in an emergency. In this paper, a certain type of internal combustion forklift truck, for example, describes the working principle of the accumulator alarm device and troubleshooting methods. 1. Working principle The accumulator alarm device structure as shown in the figure, which consists of a check valve 1, oil chamber 2, energy storage spring 3, low pressure alarm switch 4 and safety valve 5 and other components. The pressure oil output by the brake pump enters the oil chamber 2 through the check valve 1 to compress the energy storage spring 3 so that the pressure energy of the oil liquid can be converted into the potential energy of the energy storage spring 3 being compressed. The function of the check valve 1 is to prevent oil from flowing backward from the pressure oil inlet. Low-voltage alarm switch 4 is the diaphragm normally closed switch, when the hydraulic pressure in the oil chamber 2 is higher than 3.9M Pa, the low-pressure alarm switch is off, will be reported
