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、打眼一次自动完成。

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.

封层压裂时，为使暂按泵注程序对射孔孔眼进行封和解封，需要对压裂的泵注排量提出要求。
