一、自控仪的必要性 小型斜面升船机采用高低轮和宽窄轨,利用惯性过顶。能否安全过顶,取决于准确地选择过顶前牵引电动机的断电点和过顶后电动机的反转通电点。过早断电,则不能过顶;过晚则发生冲击,甚至断缆飞车。过早反转通电,缆绳过松,过晚则也发生冲击,甚至带缆飞车。 准确的断电点应保证承船车在断电后有足够大的动能作惯性运动,使之刚好能冲过 First, the need for self-control instrument Small bevel lift ship using high and low round and narrow rails, the use of inertia over the top. Whether the safety of over-top, depends on the exact choice of over-the-top traction motor off point and over-the-top motor reversal energized point. Premature power failure, you can not over-head; impact too late, and even cable car. Reversing the power too early, the cable too loose, too late, the impact also occurred, and even cable car. Accurate power-off point should ensure that the carrier car after power has enough kinetic energy for inertial movement, so that just crossed
