Causes of vibration in hot water boiler pipes

Causes of vibration in hot water boiler pipes

The hot water boiler is equipped with a computerized boiling water boiler controller. All the functions are stored on a smart chip, which realizes the intelligent, digital, automatic and humanized boiler. The boiler intelligently controls the water temperature, and the water temperature heating automatically stops; the screen large font The water temperature is displayed and the temperature of the furnace water is clear at a glance.

 

The temperature of the boiler water in the hot water boiler can be set freely from 10 ° C to 100 ° C. The boiler can supply hot water and provide boiling water for drinking. It can be used in one furnace.

 

The top of the furnace body of the hot water boiler is provided with an atmosphere, the boiler is in a non-pressure state, and there is no danger of explosion. The whole machine is equipped with overheat protection at the same time. (When the water temperature in the furnace is too high, the heating tube automatically stops working and buzzer alarm, twice Overheat protection (automatically cut off the secondary circuit when the boiler shell temperature exceeds 105 °C), anti-dry burning and water shortage protection (when the boiler water is lower than the extremely low water level, the boiler stops working and emits a buzzer alarm) and many other safety protections.

 

First of all, the vibration of the hot water boiler pipe is caused by unreasonable installation of the pipe. 1. The pump is not fixed. Generally, the pump must be a concrete (casting) base, or the pump can be fixed by means of channel steel and expansion bolts.

 

2. The water pump inlet and outlet should use soft connection, which can effectively prevent the pipeline from vibrating. 3. Some flanges and valves are not fixed at the bolts, which will also cause the pipe to vibrate. 4. The bottom of the pipe should be stable.

 

After every 3-6 months of operation of the hot water boiler, the furnace should be shut down for comprehensive inspection and maintenance. In addition to the above two tasks, the following work must be carried out:

 

(1). Remove the scale and sludge from the inside of the drum, the water wall and the left and right headers, and rinse them with clean water.

 

(2). Remove the scale and coal ash from the water wall pipe and the fire surface of the drum.

 

(3). Check whether there is corrosion inside or outside the welded steel plate of the boiler. If there is serious defect, it should be repaired immediately. If the defect is not serious, it can be left for repair at the next shutdown. If suspiciousness is found, it does not affect the safety production. , should 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 if the rolling shaft of the induced draft fan is normal, and the degree of wear of the impeller and the outer casing.

 

(6) If necessary, remove the furnace wall and the outer casing, Moisturizing layer, etc., for thorough inspection. If serious damage is found, it must be repaired before continuing to use. At the same time, the inspection results and repairs are filled in the boiler operation registration. Book .

The most lucrative industry is fashion and cosmetics. Cosmetic Raw powders are hot selling products now. Let`s talk about several Cosmetic Raw powders here.Kojic acid, is a kind of organic compound antioxidant and radiation protection agent. It is used in Cosmetics. In human skin, tyrosine is catalyzed by tyrosinase to Synthesize Melanin through complex oxidation and polymerization with oxygen free radicals. Kojic Acid can inhibit the synthesis of tyrosinase, and thus can strongly inhibit the formation of melanin, and safe non-toxic, does not produce white spot sequela, so Kojic Acid has been allocated into lotion, facial mask, lotions, creams, can effective treatment of freckles, age spots, pigmentation, acne and other high-grade whitening cosmetics..
