矿井提升绞车的储力器是供给制动系统的储能机构。它能否正常运行,直接威胁着提升绞车的安全运转。我矿一井一号竖井提升绞车,过去曾由于储力器电器终断开关失灵,发生过重锤坠落事故。为防止类似事故的再次发生,我们曾先后将 KJ_2×3×1.5D—20和 KJ_2×2.5×1.2D—20型提升绞车加设了机械安全释压阀。通过多年的生产实践,证明它动作灵敏、安全可靠。
The energy storage device of the mine hoisting winch is the energy storage mechanism for the brake system. Whether it can operate normally and directly threaten the safe operation of the winch. I mine a well shaft hoist winch, in the past have been due to failure of the electrical switch fuse switch, heavy hammer crashed accident occurred. In order to prevent the recurrence of similar accidents, we successively added mechanical safety pressure relief valve to KJ_2 × 3 × 1.5D-20 and KJ_2 × 2.5 × 1.2D-20 hoisting winch. After many years of production practice, it proved to be sensitive and safe.
