Causes of vibration in hot water boiler pipes

The reason why the hot water boiler pipe vibrates is that the hot water boiler is equipped with a computer-based boiler controller All the functions are stored on an intelligent chip, which realizes the intellectualization, digitalization, automation and humanization of the boiler The boiler intelligently controls the water temperature to achieve the automatic stop of water temperature heating The water temperature is displayed in large font on the screen, which is clear at a glance The water temperature of hot water boiler can be set at will from 10 ℃ to 100 ℃ The boiler can not only provide hot water for bathing, but also provide boiled water for drinking, which can be used in one boiler for both purposes
The top of the hot water boiler body is equipped with an air port, the boiler is in a non pressure state, and there is no risk of explosion The whole machine is also equipped with overheat protection (when the water temperature in the boiler is too high, the heating pipe automatically stops working and beeps for alarm, the secondary overheat protection (when the shell temperature of the boiler exceeds 105 ℃, the secondary circuit is automatically cut off), and the protection against dry burning and water shortage (when the boiler water is lower than the extremely low water level, the boiler stops working And send out beep alarm) and other safety protection First of all, the vibration of the hot water boiler pipeline is largely caused by the unreasonable installation of the pipeline 1 The water pump is not fixed properly Generally, the water pump should be made with concrete (pouring) base, or fixed with channel steel and expansion bolt 2 The inlet and outlet of water pump shall be connected with soft connection, which can effectively prevent pipeline vibration 3 Some flange and valve bolts are not fixed well, which will also cause pipeline vibration 4 The bottom of the pipeline shall be provided with a stable frame After the operation of the hot water boiler every 3-6 months, the boiler shall be shut down for comprehensive inspection and maintenance In addition to the above-mentioned work, the following work shall be carried out: ⑴ clear the scale and sludge inside the drum, the water wall and the left and right headers, and wash them with clean water (2) remove the smoke and ash on the fire surface of water wall pipe and drum (3) check whether there is corrosion inside and outside the welded steel plate of the boiler If there is serious defect, repair it immediately If the defect is not serious, it can be left for repair when the boiler is shut down next time If there is any doubt, but it does not affect the safety production, make a record for future reference (4) after the inspection, the boiler paint can be painted on the fire surface to prevent corrosion (5) check whether the rolling shaft of induced draft fan is normal and the abrasion degree of impeller and shell (6) if necessary, remove the furnace wall, outer cover, moisturizing layer, etc for thorough inspection If serious damage is found, it must be repaired before use At the same time, fill the inspection results and repair conditions into the boiler operation register
