Fluid submersible pump is a kind of energy conversion device, it is driven by the driving motor (or engine) and realize the conversion of mechanical energy into energy conversion of pressure energy of hydraulic oil, and then promote the work of mobile crane Institutional work. Hydraulic pumps used in hydraulic transmission is sealed by the changes in the work volume to work, it is a positive displacement pump. Hydraulic pumps commonly used on cranes include gear pumps, vane pumps and axial piston pumps. Submerged pump mainly by the impeller, shaft, pump housing, shaft seal and seal ring and other components. When the prime mover drives the pump shaft and the impeller to rotate, the liquid, on the one hand, makes circular motion with the impeller on the one hand and is thrown out from the center of the impeller to the outer periphery under the centrifugal force on the one hand. Hydrostatic pressure and hydrodynamic pressure were obtained from the leaves. When the liquid flows through the volute to the discharge port, some dynamic pressure can be converted into static pressure energy. When the liquid is thrown from the impeller, the central portion of the impeller causes a low-pressure region, which forms a pressure difference with the pressure of the suction liquid, so that the liquid is continuously sucked and discharged with a certain pressure. For ordinary submersible pumps, the shaft seal is filled with or without sealing requirements; when the medium is conveyed containing gas or its vaporization, the sealing requirements are relatively stringent; when the transport of molten salt at high temperature, this submerged pump is Molten salt under the pump, then seal to take into account the special requirements of high temperature. Submerged pump structure Submerged part of the working fluid submerged in the liquid pump, shaft seal no leakage. And covers an area of ​​small, reliable, easy maintenance, corrosion resistance and so on. Submerged pump is widely used in chemical, pharmaceutical, paper, petroleum and other industrial sectors. The vertical motor of the submerged pump is bolted to the motor seat, directly driven by the elastic coupling and the pump, the pump body, the intermediate takeover pipe, the pump rack, the liquid outlet pipe and the pipe flange are integrally connected by a bolt and fixed On the bottom plate, the entire submerged pump is mounted on the container through the bottom plate. Pump axial force and radial force, (including the pump during the operation of the water pressure, impeller and rotor weight, etc.), by the bearing box installed within the one-way thrust ball bearings, single row radial ball bearings; and sliding guide Axis to withstand the normal operation of the pump to ensure safety. Bearings lubricated with butter, guide bearing lubrication with the transport of liquid. Therefore, when the submerged pump work surface level must be higher than the impeller. Into the length of the container length L different, then divided into intermediate guide bearing structure and no intermediate guide bearing structure. Submerged pump works: the motor through the coupling and pump shaft connection, impeller rotation. Impeller blades force the liquid to rotate, do work on the liquid to increase its energy, the liquid in the centrifugal force, thrown around the impeller, through the pump body flow velocity can be converted into pressure, when the impeller After the liquid is thrown out, the pressure in the impeller is lower than the pressure in the water inlet pipe. The new liquid sucks the impeller under the pressure difference and the liquid continuously flows out of the pump. Submerged pump according to the length of the container into the different (usually 1 to 1.5m) made of specifications. Submerged part of submerged pump liquid in the pump, the pump operation of the axial and radial forces were supported by the rolling bearings and plain bearings; therefore quiet and quiet operation. Shaft seal no liquid splash phenomenon. Seal packing at the cooling system, according to the user using the media temperature, with cooling water away heat. Underwater pump structure: [Editor's note] how? Above the submerged pump structure is not to understand the submerged pump you solve the urgent need? In the future there are more exciting technical interpretation of the fluid machinery industry products, please feel free to pay attention to the Asian Fluid Network.

Acetic Acid is a colourless liquid organic compound with the chemical formula CH3COOH . When undiluted, it is sometimes called Glacial Acetic Acid. As one of most important organic raw materials, it is mainly used in vinyl acetate, acetic anhydride, acetate ester, acetate, acetate fiber and chloroactic ACID etc. It is an important raw material for syntesized fiber, gooey, medicines, pesticides and dyes, and also a good organic solvent. It is widely applied in industries of plastics,printing and rubber etc.
Appearance:
transparent liquid; Pungent odor,miscible with water,alcohol,ether and carbon tetrachloride; insoluble in carbon disulfide.
