Ductile Manhole Cover is made of ductile;
we make the manhole cover on BS EN124, Mainly our products are A15, B125, C250
and D400, sometimes also make it E600 and F900 in case of need. For A15, B125,
C250 and D400 ductile manhole covers to be used in Green belt, Pavement, Auxiliary
road, Main road and Express way. We make ductile manhole covers all by
producing line, the quality is very good, and we warmly welcome customers all
over the world to do business with us.

Horizontal split multistage centrifugal pump structure diagram introduction
Multi-stage centrifugal pump with energy-efficient hydraulic model, with high efficiency and energy saving, low noise, easy installation and maintenance, etc., in our production and life has an important role. Today, Xiao Bian to introduce a multi-stage centrifugal pump, let us look at the horizontal split multi-stage centrifugal pump structure introduced it. 1, pump light 2, the pump body 3, the bearing body 4, the sleeve 5, the impeller 6, the pump shaft 7, the shaft head pump horizontal split multi-stage centrifugal pump with a volute pump body, the periphery of each impeller The corresponding volute, equivalent to a few single-stage volute pump installed in the same axis in series, so called volute multistage pump. As the pump body is split horizontally, the suction inlet and outlet are cast directly on the pump body, easy maintenance, just remove the pump cover to expose the entire rotor, the rotor in the repair, the entire rotor When hanging out, it is not necessary to disassemble the connecting pipe. The impellers of such pumps are usually symmetrically arranged in an even number and most of the axial force is balanced so that no axial balancing device is required. Horizontal split multistage centrifugal pump flow range of 450 ~ 1500m / h, the maximum lift up to 1800mHz0. As the impeller symmetrical arrangement, the cross-flow channel within the pump shell, so it is more than the same performance of the multi-stage multi-stage pump volume, casting process complexity, pump cover and pump positioning requirements, high pressure, pump cover And the sealing surface of the pump body is difficult to seal. The above is the horizontal split multi-stage centrifugal pump structure introduced, I hope everyone's help to learn, followed by small series will introduce the segmented multi-stage centrifugal pump structure, so that we understand as much as possible centrifugal pump structure Kind of figure Further Reading: pump valve pipe fittings Exhibition Water Expo Xiamen exhibition of marine equipment Internet + Forum Yiwu Fair 2016 exhibition mold top ten brands of the Internet information industry (Xiamen) Technology Co., Ltd.
