The pump belongs to the centrifugal pump range, the structure and principle of the pump and the general centrifugal pump is the same
Ordinary water pumps are designed for maximum efficiency, that is to say the water pump's hydraulic structure parameters are the best combination for maximum efficiency. Sewage pumps, such special requirements of the pump efficiency can not exceed the same period of the efficiency of the pump.
The main reason that water pumps are less efficient than clean water pumps is that their overcurrent channels widen. The decrease in efficiency is mainly related to the degree of broadening. Clear water pump runner is to prevent blockage.
Sewage pumps are centrifugal pump range, structure and principle and the general centrifugal pump is the same. Clear water pump also has its own structural features, sewage pump lift is not high, due to debris in the sewage more, the gap between the impeller than the large water pump. Clear water pump prone fault, and the general centrifugal pump is also similar, because pumping sewage, so impeller wear faster.
Sewage pump impeller than the water pump is simple, there is no guard ring, so that will not live in the grass, there is a serrated blade below the impeller, clear water pump can be adjusted up and down, can thread, cloth pieces and extracted.
Winch Hoist is a open winch used as a hoist for Double Girder Overhead Crane, Double Girder Gantry Crane, etc. It can be also used as the gate hoist for hydropower station dam. The open winch hoist is an electric crane widely used in buildings, bridges, metallurgy, mining, etc. for lifting of materials, hoisting projects and dragging of various materials and equipment.
Open winch hoist is also used to pull or lift heavy objects in road and bridge projects, civil construction, mining area, factory, port, marine, etc. For example, Installation and disassembly of large or extreme large steel structure and machinery equipment, reinforce concrete, drag ships, etc.
While the gate winch hoist is for hoisting spillway gates, tailrace gate and other gate of hydropower plant. The gate winch hoist is mainly used for hydraulic equipment transport, installation and maintenance of hydroelectric generating units, hoisting of floodgates, trash rack etc.
