定筒式顶部固定杆式泵设计 摘要：随着国内大部分油田已进入开发中后期，管式泵的诸多优点逐渐变得不再明显；而杆式泵在检泵过程中不需取出油管、作业成本低、作业时间短等优越性则日趋凸现。因此，研制适应油田开发规律，在性能、规格、种类和适用性等方面具有更高要求的杆式泵成为迫切需要。 定筒式顶部固定杆式泵特点：锁紧装置位于顶部，柱塞运动时可将锁紧装置四周的砂粒冲掉，防止砂卡，使起泵作业容易；泵筒可绕顶部锁紧装置这个支点摆动，在斜井中下泵时，泵筒和油管都不会损坏；在固定位置相同的情况下，泵的沉没度较底部固定杆式泵稍大，更适合在低产井和低液面井使用，顶部固定装置使泵本身具有气锚作用，可在含气较多的油井中使用。 关键词: 顶部固定杆式泵；柱塞；泵筒；杆式泵；管式泵 Drum set at the top of the fixed rod pump design Abstract: With most of the domestic development of oil has entered the late-tube pump gradually become less obvious advantages; and rod pump in the inspection process without removing the pump tubing, low operating costs, and shorter operating time, the superiority of the Increasingly apparent. Therefore, the development of laws to adapt to oil field development in performance, size, type and applicability has become more demanding urgent need for the pump rod..朗读 The top of the fixed rod pump drum set features: locking device at the top of the plunger movement can wash away the sand around the locking device to prevent the sand card, so that easy operation from the pump; pump around the top of the lock cylinder can be This compact device swinging fulcrum, the lower the pump in the shaft when the pump barrel and tubing are not damaged; in a fixed position under the same circumstances, submergence depth of the pump rod pump is slightly larger than the bottom is fixed, is more suitable for low-yield wells and low Use of surface wells, at the top of the pump itself fixtures gas anchor role, more in gas wells in use. 显示对应的拉丁字符的拼音 ? 字典 Key words: Top of the fixed rod pump; plunger; pump barrel; rod pump; tube pump
