Installation and maintenance of MAZDA Brazed Radiator
MAZDA Brazed Radiator is a kind of oil cooling equipment commonly used in power system, and also applicable to metallurgy, chemical, mining, light industry and heavy industries. Let's take a look at the problem of installation and maintenance of MAZDA Brazed Radiator.
1, right place MAZDA Brazed Radiator, guarantee feed, oil pipe connection position relatively accurate, general should be installed in the system back to oil or is lower than the design pressure system, the oil side pressure side pressure should be higher than water.
2. The flange of the water outlet pipe and the installation of the foot screw should be installed on site.
3. All pipe flanges and valve seals shall be sealed without leakage.
4. Before the MAZDA Brazed Radiator is moved, the pipe should be cleaned to prevent the debris from blocking the cooling pipe.
5, MAZDA when brazing radiator was put into operation, should slowly open the throttle and object completely (straight) line as the gas inside the shell, you can close the object completely door, and open the export gas, then fully open MAZDA Brazed Radiator outlet gate, slightly open at the top of the water side object completely, after air is put off, according to the MAZDA Brazed Radiator outlet oil temperature adjusting the watergate (in open water valve, gradually increasing traffic), adjust to keep the oil temperature is normal.
6. If the air in the heat exchange tube is not exhausted, the heat transfer performance will be bad.
7. When the MAZDA Brazed Radiator is stopped during the severe winter season, the cooling water in the MAZDA Brazed Radiator should be exhausted to avoid frostbite equipment.
When the MAZDA Brazed Radiator is discontinued, it should turn off the oil and water into the valve in turn, discharge the valve of the oil and water, loosen the screw in the drain drain, and put out the water and oil in the inside.
9. The MAZDA Brazed Radiator is used to apply kerosene (gasoline) to wash the cooling tube, the end cover and the shell in about a year, and the reassembly shall be conducted with no leakage test of 1.25 times pressure.
MAZDA Brazed Radiator is very widely used in modern our domestic production industry a MAZDA Brazed Radiator, which bring great convenience to our production and work. If you want to make the oil MAZDA Brazed Radiator for longer service life, reduce the generation of fault, so we shall timely cleaning, here small make up mainly introduce in cleaning oil MAZDA Brazed Radiator of the two methods.
Water side cleaning: clean the front cover of clean water with the hose, the inner wall of the back cover and the inner surface of the heat exchange tube, wash with the cleaning agent, and blow dry with compressed air after washing
Oil side cleaning:
(1) choose a suitable cleaning agent, the content is very important, we usually according to the tube produced by some impurity elements to determine choice is organic acid cleaner or inorganic acid detergent, choose a suitable cleaner can help us easily to remove impurities.
(2) chemical b dilute solution to wash, make the cleaning fluid circulating in the MAZDA Brazed Radiator, solution of pressure is not greater than 0.6 Mpa, the flow of solution and the best MAZDA Brazed Radiator oil flow in the opposite direction, cleaning time subject to dirt, then water pumping MAZDA Brazed Radiator inside cleaning, until the water clean.
(3) the solution into the MAZDA Brazed Radiator with immersion method, 15-20 minutes to check the solution color, if be turbid, the new solution, to soak, until clean, then rinse with clear water.
Cleaning process requirement is very strict and important, after using acidic detergent cleaning shall be conducted by alkaline clean water is needed to clean, such neutralization after rule out completely, can help us to put the oil MAZDA Brazed Radiator more clean, clean thoroughly.
