eyelets

The machine can automatically punch or continuously punch and rivet eyelets. The punching and eyeleting can be finished once.

该机具有单打或连续钉打鞋眼、冲孔、打眼一次自动。

While conducting hydraulic fracturing, the flow rate is required to be controlled to enable the hall-off to block off and uncord the eyelet based on the stimulation process.

堵球分层压裂时，为使暂堵球按照施工序对射孔孔眼进行堵和解，需要对压裂施工的排量提出要求。
