overview

The LDTN type condensate pump is suitable for transporting condensate water from the condenser of thermal (nuclear) power plants. It can also be used in chemical processes with NPSH or installation surface restrictions to transport media with physicochemical properties similar to water. The operating temperature should not exceed 80 ℃ The LDTN type consists of four major components: a circular cylinder, a motor, a pump, and a motor shaft, which are shipped separately and require on-site assembly and debugging during installation.

Purpose and scope of use

1. Purpose: Suitable for conveying condensed water in fire (nuclear) electric thermal systems, as well as for conveying media with high physical and chemical properties similar to water in chemical processes where the installation base of NPSH is limited.

2. Scope of use:

Flow rate: 160~350m ³/h Head: 48- 175m

Medium temperature, normal temperature~80 ℃ (special requirements can reach 120 ℃)

structure

1. Structural form: LDTN pump is a vertical double-layer shell structure; The impeller is enclosed and arranged in the same direction, and the guiding element is a bowl shaped shell. The inhalation and exhalation interfaces are located on the manifold and exhalation seat respectively, and they can be adjusted at multiple angles such as 180 ° and 90 °.

2. Structural composition: The LDTN type polymer consists of three main parts: the pump casing, the working part, and the outlet part.

1) Pump Simplified Body: The pump simplified body is a national shaped simplified body made of high-quality carbon steel plate rolled and welded into stainless steel plates, with a suction port flange on one side. The pump casing is used to form the outer pressure chamber of the double-layer shell spring, and the chamber is in a negative pressure state during normal operation.

2) Work Department: The work department is composed of a pump rotor with multiple impellers arranged in the same direction and a guide shell forming a guide space on its periphery.

The pump rotor consists of impellers, pump shafts, conical sleeves, bearing bushings, and other components.

The impeller is the core component that converts the energy of the prime mover into the energy of the liquid being transported.

The pump shaft serves as both the carrier of the impeller and transmits all the load of the rotor.

The connection between the shaft and the impeller is a simple clamping sleeve connection.

The function of the guide shell is to guide the liquid flowing out of the impeller evenly into the next stage through loss
