JDTN series of condensate pump

1, structure type: type JDTN condensate pump is vertical double hull structure; Impeller is enclosed and synthetic array, diversion components for cup shell. Breathe with the interface in the pump cylinder and spit out, they can do 180 °, 90 ° deflection from multiple perspectives.

2, structure: JDTN type pump is composed of three parts, namely: the pump barrel, work and the water part.

1) pump cylinder, pump barrel is made of high-quality carbon steel or stainless steel plate roll welding of circular cylinder parts, the side is equipped with suction flange. Pump barrel to form double shell outer pressure of the pump cavity, the lumen is in a state of negative pressure in normal working conditions.

2) work: work with synthetic arrangement of multistage impeller pump rotor and diversion from forming on the outer space of the diversion shell together.

Pump rotor by the impeller, pump shaft, taper sleeve, bearing bushing, etc.

The energy of the impeller is the prime mover converted to energy pumping liquid core components.

Pump shaft as the carrier of the impeller, both pairs of transmitting the full load of the rotor.

Pump shaft is connected with the impeller clamping sleeve connection.

The role of diversion shell with minimal losses will flow impeller liquid evenly into the next level of impeller after orientation. Diversion shell connection is between positioning, screw fastening.

Part 3) water: water part by variable diameter tube, round tube, such as the spit. Condensate pump intermediate shaft, the shaft from that part of the centre. From the pump work after this part of the nearly horizontal flow of liquid into the pressure pipeline pump. Spit on stuffing box, vapor pressure relief hole, hole. Pressure relief hole to minimizing the shaft seal cavity pressure; Steam to take off the hole for the pump cylinder body of gas in a timely manner to the condenser.

3, bearing, pumps with how water lubricated bearing, used to withstand the pump rotor radial force. Axial force by the motor pump rotor thrust bearing.

4, shaft seal, shaft seal adopts M7N / 43 - G9 mechanical seal, need for sealing water injection. Seal water demanded to see the random product appearance figure.
