矿井提升机安全制动与防滑安全区域

对矿井提升机液压制动系统整定公式计算表明,在一般情况下,油压值允许有一定的整定区间,而不是以往常用的特定值。将使设计、调试与日常维护工作简便易行。还对多绳摩擦提升系统的防滑问题作了综合性讨论,提出“安全区域”概念,将防滑计算归结为平面图像问题,直观明了。并从设计角度举例说明之。

Range of Secure Braking and Anti-sliding Safety for a Shaft Hoist

The rectication formula derived in the paper shows that the pressure of the hydraulic braking system is generally admitted of a definite retifying range, rather than a specific value used commonly. It makes designing,debugging and routine maintenance simple and easy. Besides,this paper discusses synthetically the subject of anti-sliding, puts foorward aconception of "safety interval" and therefore makes anti-sliding calculation an intuitional ichnography which is illustrated with an example from the view of designing.
