一种确定循环泵瞬时扭转力的机械方法是机械转矩系数法,就是用扭转因子,光杆负荷,位置系数以及平衡重量来确定的。
这个太专业了,不懂……

A mechanical method for determining the instantaneous torque throughout the pumping cycle is the mechanical torque factor method, which uses torque factors and polished-rod load and position data together with counterbalance weight.
在泵的循环中确定瞬时扭矩的机械方法是机械扭矩因数法,这种方法用到扭矩因数、光杆载荷、位置数据以及对重(平衡块)重量。
The instantaneous gearbox torque at a given polished rod position (whether on the polished rod upstroke or downstroke) is the torque factor at that polished rod position multiplied by the net gearbox load at that position.
在一个指定光杆位置的瞬时变速箱扭矩(无论是上行还是下行冲程)等于那个光杆位置的扭矩因数乘以那个位置的变速箱净载荷。
During weight box ascent (polished rod downstroke), the net load on the gearbox is the weight of the counterweight box less the polished rod load.
在对重箱上升时(光杆下行冲程),变速箱的净载荷等于对重箱的重量减去光杆载荷。
During the weight box descent (polished rod upstroke), the net gearbox load is the polished rod load minus the weight of the counterweight box.
在对重箱下降时(光杆上行冲程),变速箱的净载荷等于光杆载荷减去对重箱的重量。
The net load can be positive or negative.
净载荷可以是正值或者负值。
For PNT pumping units, mechanical torque factors (TF) are normally calculated from the geometry of the particular PNT pumping unit, and the torque factors are calculated relative to the position of the polished rod.
对点式泵单元,机械扭矩因数通常通过具体点式泵单元的几何特征来计算,扭矩因数相对于光杆的位置来计算。
Torque factors are positive (+) on both the upstroke and the downstroke.
无论上行冲程还是下行冲程,扭矩因数都是正值。
The torque factor is the same value at any polished rod position whether the unit is on the upstroke or downstroke.
无论单元处于上行冲程还是下行冲程,在相同的光杆位置,扭矩因数的值是相同的。
今天下午帮你翻的那一段,factor翻译成了“参数”,现在揣摩起来,还是“因数”比较合适
