AI Technical Summary
Traditional drilling fluid vibrating screens have insufficient connection strength, making them prone to loosening and affecting the normal operation and service life of the equipment.
The inner convex ring and upper grid, made of composite resin material, clamp high-mesh and low-mesh screens with the inner frame and lower grid, and are connected by screws and threaded sleeves. Combined with the insertion ring and the ring groove of the composite outer frame, the connection strength and rigidity are enhanced.
It improves the durability and stability of the screen, extends its service life, reduces maintenance difficulty, and is suitable for harsh drilling environments.
