1. structural features and working principle
This machine is a manual type, the range of the opening in the Phi Phi 100 40-, suitable for small and open multi bypass hole, pressure balance hole and discharge hole. He is shaking the direct drive through the human Daolai hole drill rod drives the cutting hole. It adopts the casing thread and the nut sleeve is connected with the feeding hole, the pattern set, a marked with scales, indicating direct feed depth.
The head of the rotating machine can be used for quick lowering of the knife and lifting the knife, and also for blocking the installation or extraction of flanges. But when the cutting hole should control the machine head, gently shaking the head above the handle, slowly rotating machine head, cutting tool control host. Slow feed, each machine head rotation, strength should not be too large, to maintain uniform cutting, to ensure the success of each opening hole (recommended for the first time before opening the hole and our technical personnel to do technical communication on the phone)
The machine body is light and small, easy to carry and easy to operate. Its shape and structure are shown in figure 1.
2. scope of application
The product is suitable for the transmission pipeline with pressure, flammable, explosive, poisonous and harmful liquid or gaseous medium, such as crude oil transportation, gas transportation, water supply, heat supply and other pipelines.
3., the product to adapt to the transmission pipeline medium pressure and temperature:
When opening a bypass hole, less than or equal to 20 DEG ~80 DEG 4.0MPa
