Automatic Condenser Brass Tube Cleaning Systems
For central air conditioning condenser and evaporator pipe, it is easy to be scaling. The normal daily water treatment should be processed during the summer time cooling water supply period,otherwise, the condenser will run in the high degree hardness water system,inorganic salts dissolved in circulating cooling water system will be crystallized and precipitated out ,scales will be formed on the tubes of condenserand it will reduce heat exchange efficiency. as hard scale increased, energy-consumption will be increased, when the knot hard mass scale is 1mm in thickness,the energy cost will be increased by 6%~10%; as water form scales with dirt, sediment, and rot colonization dirt, also the bacteria, and algae, microbial and its secretion form bio stick mud, it will attach in the pipes of condensation device, seriously it will caused pipeline block.Dirt and mud will effect hot exchange efficiency, higher energy cost will lead to high power voltage, seriously it cause super pressure voltage tilldowntime. Allthese factors affect the normal operation of the heat exchanger.
Condenser online cleaning equipment is the best effectively cleaning equipment for central air conditioning chiller cooling pipes . The performance of this device will influence cleaning and heat exchange efficiency of the main engine cooling pipe. Central air-conditioning market hasbeen expanded in recent years, condenser online cleaning device is widely used for cleaning central air conditioning chiller, with continuous working without lowering the load ,it can clean online at any time,which keeps the cooling pipes to beclean, prolong the life of cooling pipes, reduce labor intensity and increase economic benefits.
Condenser online cleaning device is an indispensable device for safe and economicoperation in central air condition system.
Working Procedures
The cleaning balls are introduced and removed from the system through the ball collector. The collector interior is partitioned by a screen into two areas. When the collector is in the ball collection or retention mode the screen separates the collector inlet and outlet. When the screen is positioned such that the inlet and outlet are no longer separated, the balls are conveyed by the flow to the injection site(s). The balls are injected into the cold leg of the circulating cooling water system serving the condenser or heat exchanger so as to achieve a random distribution within the stream. Because the balls (when deaerated) have nearly the same specific gravity as the cooling water, they follow the same path as the water within which they are suspended.
Ball Collector in the open (recirculation) mode. Both the inlet and outlet of the collector are on the same side of the collector screen.
Ball Collector in the collection (ball capture) mode. The screen has been rotated so as to separate the inlet and outlet of the collector.
When the ball charge is correctly sized, each tube is treated by a ball approximately once every five minutes. When the balls have passed through the tubes and enter the cooling water discharge line they are intercepted by the ball strainer(s). When the balls meet the strainer screen they are driven along the screen surface to the ball extraction port located at the point where the down stream extremity of the screen meets the spool body. The balls are then conveyed by a special pump through the ball collector and once again to the injection site.
