      Structure of condensate pump

      Release date:2015-06-15 15:49 Source:http://www.biricikmaket.com Views:

      Condensate pump heads of the shell is in a bowl shape shell or spiral shell, secondary and final shell is bowl shaped shell; pump shaft with radial bearing, rotor axial load can be borne by the pump itself thrust bearing, can also be borne by the motor; shaft seals for packing seal or mechanical seal, pump rotor system with two shaft, shaft is connected to the card ring cylinder type coupling, pump connection for elastic column pin coupling or rigid coupling connection; inhalation and spit out the interface are respectively located in the pump barrel and spit out the seat, and a 180 DEG from the horizontal layout (according to the integer times of 15 DEG arbitrary displacement).

      10NL-12 type condensate pump structure, as shown in the diagram below, from the pump body 2 and pump cover 6 of the studio, is vertical to the joint surface of the split, easy to disintegration. The main impeller 1 is provided with a spiral inducer 3. It is made of aluminum iron bronze. Condensate from the hot well, after condensation pump inducer 3, and then enter the main impeller of centrifugal type 1, which is made of copper and molybdenum iron. Spiral inducer 3 although efficiency is low but the suction performance is better, the main impeller imports 0.098 MPa (10 water) pressure head, so that the main centrifugal impeller in high speed rotating work, not by serious cavitation effect.

      Because of the unilateral water, there is inevitably axial thrust in the impeller, this thrust with the balance of water mains 25 to balance the pipe and pump body cast as one, connected with the pump inlet. Pump inlet in the vacuum pump, the pump body inlet with vent pipe 26, it is also cast in one with the pump body, this gas tube directly connected with the steam side of the condenser. Main impeller and induced wheel with flat keys, shaft sleeve, a positioning sleeve and round nut fixed on the shaft, one end of the shaft is equipped with elastic backed by 24 rounds, directly connected with the motor. The motor is fixed on the bearing bracket body 23 and three root pillar 22 support bracket bearing body on the base (21) to reduce the pump body weight load. The electric motor is located in the bearing bracket body 23. Condensate pump
