ã€Centrifugal Fluid Network News】 Centrifugal pump used in the open rear structure design, with its energy-saving, efficient, convenient and other advantages continue to highlight the clean water centrifugal pump has become one of the key pump products in China. Next, we will bring clear water centrifugal pump structure and structure of the introduction. Centrifugal pump structure and structural features of a clear water centrifugal pump is based on international standards ISO2858 performance and size of the design, mainly by the pump body, pump cover, impeller, shaft, seal ring, bushings and suspension bearing components composition. 2, clean water centrifugal pump housing (ie, pump body and pump cover) constitute the pump studio. Impeller, shaft and rolling bearings for the pump rotor. The suspension bearing part supports the rotor part of the pump, which is subjected to the radial and axial forces of the pump. In 3, the water centrifugal pump In order to balance the pump axial force, the majority of the pump impeller front and rear are equipped with a seal ring, and the impeller rear cover with a balance hole, due to some pump axial force is not large, impeller back No seal ring and balance hole. 4, clean water centrifugal pump in order to avoid shaft wear, the shaft through the packing chamber parts with shaft sleeve protection. There is an O-ring between sleeve and shaft to prevent air ingress or leakage along mating surfaces. 5, clean water pump and pump cover part of the centrifugal pump is split from the back of the impeller, which is commonly referred to as the rear door structure. The advantage is easy maintenance, maintenance pump body, suction line, exhaust pipe and motor, just remove the longer coupling intermediate coupling, you can exit the rotor part of the overhaul. 6, fresh water centrifugal pump axial seal ring by the packing gland, packing rings and packing and other components to prevent air or large water leakage. If the pump impeller is balanced, the cavity filled with soft packing communicates with the suction inlet of the impeller. If the liquid at the inlet of the impeller is in a vacuum state, it is easy to enter the air along the surface of the sleeve, so the packing ring is filled in the packing chamber Small holes on the pump cover, the water pressure in the centrifugal pump to the packing ring seal. Pump impeller, such as no balance hole, because the liquid pressure on the back of the impeller is greater than atmospheric pressure, so there is no leakage problem, it can not fill rings. Through the above water centrifugal pump structure and structural characteristics of the analysis of the basic knowledge of water centrifugal pump we have further deepened. The future of clean water centrifugal pump market will certainly be more broad, but the premise is that water centrifugal pumps have sufficient market competitiveness. In the face of this cruel pattern, clean water centrifugal pumps need continuous breakthroughs, and perhaps we can do more work from the clean water centrifugal pump structure and structural features.

A good Bi-metal Hole Saw will cuts faster and smoother and with reduced vibration due to the variable pitched teeth, hole saws have two different types of steel joined together to form the edge of the cutting end of the Hole Saw. High speed steel is joined to a soft spring steel to form a durable edge that will cut a multitude of materials and help provide long life. High speed steel is used on the outer edge due to its wear resistance properties and forms the cutting edge of the teeth. Soft, spring steel creates a flexible backing material that allows the hole saw to absorb impacts of the job of drilling holes in difficult-to-cut materials.
