JC Long -shaft Turbine Deep Well Pump, Single suction multistage vertical centrifugal pump, with closed type or semi-open type impeller for different operation. Water lifting pipes can be connected by flange or screw type, Deep well pump can be driven by vertical motor, vertical hollow shaft electrical motor, flat belt pulley, or driven by horizontal electrical motor or diesel engine through an angle gear box. Conditions of Use:
Pumped water quality should meet the following requirements:
1. The temperature should not exceed 40 ℃.
2. Solid content (by mass) is not more than 0.01%.
3. pH PH value of 6.5-8.5.
4. Hydrogen sulfide content of not more than 1.5mg \ L.
5. Does not contain any oil.
JC-type deep-well pump by the three major components, namely, including the inlet pipe, including the work part, the water pipe part, the uphole part.
(1) Long shaft The working part of the deep well pump consists of working parts and inlet pipe parts. Working parts by the 4-1JC deep well pump structure, the lower flow shell, impeller, cone sets, bearings, impeller shaft and other components. Impeller is enclosed, located in the middle deflector shell (in the number of guide shell depends on the number of pumps). The lower deflector shell is used to connect the middle deflector shell and the inlet pipe, and the water flowing into the inlet pipe smoothly leads to the first stage impeller. The first stage of the impeller water thrown through the guide shell and then lead the second stage impeller, the second stage impeller thrown out of the water and then through the second guide shell into the third stage impeller. In turn the water level up, the water gradually increase the energy level, when the water is the last stage of the impeller thrown through the upper diversion shell into the water, the tube. The housing is fitted with a sealing ring for ease of replacement after wear, with bolted connections between the housings. The tapered sleeve is used to secure the impeller to the pump shaft, which is used to prevent oscillation of the pump shaft and to withstand the axial force of the pump. The upper end of the working part is provided with a short pipe to facilitate installation. The inlet pipe is made of short pipe, and several round holes with diameter of 10-25mm are drilled around to prevent water debris from entering impeller or blocking water pump.
(2) of the long shaft pump shaft part of the water pipe, drive shaft, coupling and bearing components and other components. Long shaft pump shaft by a number of equal length of the long pipe (each section is generally 2 ~ 2.5m long) and the upper and lower two short pipe connection, with a flange connection. The drive shaft consists of a number of equal length shafts and two short shafts, with a female coupling. Pipe and tube connection with external thread bearing body, built-in drive shaft of the rubber bearing. There is a chrome on the drive shaft, and the effective length of the chrome section is twice the length of the rubber bearing. When the shaft chrome wear, you can replace the short drive shaft installation location, the short drive shaft installed in the motor drive shaft below, so that the shaft down, can continue to use.
(3) the long axis of the well pump part of the pump seat, motor composition. Pump base to withstand the weight of all the water pipes and working parts. Pump outlet at the need to install the gate valve and check valve and the water pipe connected. Long shaft pump shaft motor shaft motor, which is a special pump motor. Its characteristic is the structure is compact, the transmission efficiency is higher.
JC-type long shaft deep well pump is suitable for extracting water from the wells without corrosive water at room temperature. It is widely used in hydropower stations (pumps for maintenance, leakage and drainage), thermal power plants (circulating cooling and domestic pumps) Pumps, fire, urban water supply and farmland irrigation.
