Product Introduction
Condenser action
The condenser is an important part of the steam turbine. Its function is to condense the exhaust gas of the steam turbine into water and maintain the required vacuum.
The condenser is an important part of the steam turbine. Its function is to condense the exhaust gas of the steam turbine into water and maintain the required vacuum.
structure
The condenser is composed of a shell, a water chamber, a tube plate, a cooling tube, an intermediate tube plate, a steam baffle and a condenser aggregator. The shell and the water chamber are welded into a whole, and the shell is a welded steel plate structure. Manhole covers are provided in the upper shell, water chamber and heating unit for easy maintenance. The tube inside the cylinder is fixed on the end tube plate by expanding tube method or expanding welding, and the tube tube with the baffle supporting tube in the middle bends upward to prevent resonance. The tube tube tube is arranged by the design technology of HEL-6, which is the international general design standard for condenser. The condenser designed by this technology is airflow centripetal type, arc arrangement and triangular arrangement, which is characterized by small air resistance and small subcooling degree.
In the middle of the bundle there is a wide steam passage from the inlet to the hot water well, and the two sides of the bundle are arranged in a belt shape, and on the outside of the belt shape, another part of the pipe for steam washing. Stainless steel pipe is adopted, and steam baffle is arranged between the steam passage to prevent steam short circuit.

Tube change
Condenser is an important cold source equipment of turbine generator set. Due to the pollution of river, lake and sea water system, the corrosion rate of condenser cooling pipe is intensified, resulting in frequent leakage of condenser, which seriously affects normal production. In particular, the copper pipe is vulnerable to corrosion by ammonia ions, sulfides and other causes leakage, and because the inner wall of the copper pipe is not smooth and easy to attach microorganisms and various dirt, the service life of the copper pipe is greatly reduced.
Our company set up a professional mechanized tube change engineering team, mainly engaged in power plant condenser, high and low pressure heater, heat network heater, oil cooler, water cooler and other tubular heat exchangers of stainless steel pipe, copper pipe, titanium pipe old pipe removal and new pipe installation project.
In the long-term practice of condenser tube change, our company has explored a set of advanced tube change technology. In the field of condenser tube replacement has a high reputation, the service made throughout most of the power plants, many times by the power plant praise.
The installation team has all kinds of special machinery and tools needed in tube change engineering such as tube drawing, tube expansion, pipe threading, pipe cutting, pipe hole cleaning, etc. Can contract all kinds of heat exchanger tube change installation projects, with a short period of time, good quality and other characteristics.
At the same time, our company also contracted to manufacture the new condenser and increase the heat exchange area of the old condenser while keeping the shell still (remove all the parts such as the end plate and partition board in the old condenser, re-arrange the tube design according to the need to increase the area, and re-process the parts such as the end plate and partition board.
5. Technical advantages:
The tube plate hole is slotted and expanded on site (copper pipe does not need to be slotted, directly expanded). Ensure that the pulling force of the heat exchange tube reaches more than 1000kg;
(1) the tube plate and the tube plate hole are restored as new, and the tube plate hole is free of burrs;
(2) The appropriate expansion rate, that is, no underexpansion and no overexpansion, to ensure that the expansion port is not loose for a long time and no leakage
(3) Independent development of a series of special tube change tools! Practical and durable;
(4) Mature and rich experience in field tube change;
(5) Professionally trained pipe change team;
(6) High quality, high efficiency, short period to complete the construction task;
(7) condenser cooling pipe material selection and operation and maintenance consultation;
(8) In the construction can be a large number of rapid all tube change, can also be done single and local tube change.
