We offer screw conveyor. A screw conveyor or auger conveyor is a mechanism that uses a rotating helical screw blade, called a flighting, usually within a tube, to move liquid or granular materials. They are used in many bulk handling industries. Screw conveyors in modern industry are often used horizontally or at a slight incline as an efficient way to move semi-solid materials, including food waste, wood chips, aggregates, cereal grains, animal feed, boiler ash, meat and bone meal, municipal solid waste, and many others. The first type of screw conveyor was the archimedian screw, used since ancient times to pump irrigation water. they usually consist of a trough or tube containing either a spiral blade coiled around a shaft, driven at one end and held at the other, or a shaftless spiral, driven at one end and free at the other. The rate of volume transfer is proportional to the rotation rate of the shaft. In industrial control applications the device is often used as a variable rate feeder by varying the rotation rate of the shaft to deliver a measured rate or quantity of material into a process. screw conveyors can be operated with the flow of material inclined upward. When space allows, this is a very economical method of elevating and conveying. As the angle of inclination increases, the capacity of a given unit rapidly decreases. 14, submerged pump keywords: submerged pump, pumps, chemical pump, water pumpdescription: the submerged pump is a kind of cantilevered submerged centrifugal pump. The bearing is above the liquid, the lower part uses sealed form. the machine is manufactured according to different requirements of the container length deepen in the liquid. As the operating parts are submerged in liquids, shaft seal has no leakage. The axial and radial direction are supported respectively by rolling and sliding bearing, so it can realize working without noise. Generally, there is a cooling system set on the higher temperature(above 300 celsius degree) medium bearing case, cold water takes the heat away. The spare parts are divided into metal and non metallic materials, which are made to be consistent with medium requirements. otherwise, the item has advantages of small size, reliable operation, convenient repairing and corrosion resistance. It has been widely used in chemical industry, architecture, manufacture, papermaking and petroleum industries. In the selection of pumps, users could explain the situation of transport medium, including the medium names, specific gravity, viscosity, temperature, corrosion and particle content.
