What to do if the heating pipe is noisy, and how to solve the noise of the radiator

During the heating season, radiators.

The central tube is full of water, so it is normal to have occasional water flow sounds, but if the water flow is too loud, then there may be several situations.

1. When the inflow and return of the water flow are not balanced, there will be a snap, pop, snap sound.

2. The interface between the heating system and the radiator is not smooth, and the heating valve is not fully opened or the opening is too small, and the valve produces a sneering sound, which may also cause the impact of heating water.

The walls of the radiators produce noise.

3. It is mainly caused by the uneven flow of water in the radiator or the erosion of debris. There are two main reasons for the sound caused by the debris in the radiator, one is that there is slag or plugging during welding, and the other is that the impurity sand in the heating system enters the radiator and precipitates, and is washed by the water flow to produce a pop, pop, pop sound.

If the water flow in the radiator is too loud and lasts for a long time, then you can deal with it with the following solutions.

1. There is a sound that cannot be ignored, and users can adjust it by themselves. First of all, the valve of the radiator should be closed for water and return, the water return valve must be closed, and then the water inlet valve should be opened, and the air above the radiator should be released. Until there is a sound, then go to ** section, until there is no sound.

2. If there is a sound in how to adjust the backwater, twist the backwater to adjust the water supply. If there is still a sound, just close one of the valves and adjust the other. The principle is to balance the inlet and return flow of the heating, so that the balance of the water flow will not impact the debris and produce sound.

When adjusting the temperature of the radiator, adjust the two valves together.

Causes and countermeasures of high noise in heating pipes:

1. The water flow rate is too fast and there is noise: the water flow is fast or the pipe diameter is relatively thin, and then the pump lift is large, and the water flow of some pipelines is too fast, so the water flow noise will generally occur in a relatively favorable loop, and the general unfavorable loop is not likely.

2. There is gas causing noise: there may be gas in places with sound, and these places are often local protrusions so that the gas cannot be discharged, mainly to see whether there are exhaust measures at the highest point of the water supply pipe, and whether the slope is correct.

3. Noise caused by local blockage or diameter reduction, including throttling of valves.

4. Water flow resonance, this can't be said, but I think it's unlikely that the water flow speed is not fast.

5. The vibration of the pump is transmitted, but if there is a long distance from the pump, this possibility is almost impossible.

1. Hold the air in the heating pipe. If there is no hydrostatic test or some other reason, there will be air inside, and if there is air inside the radiator, the hot water will collide with the radiator when it is flowing, and a sound will be generated.

Solution: Open the manual exhaust valve at the end of the radiator to remove the air accumulated in the radiator, and close the exhaust valve after water overflows.

2. There are sundries in the radiator. If the welding residue or other debris enters the radiator during installation, when the water flows from the radiator, the debris will collide with the pipe wall of the radiator and make a sound, and if there is sand in the tap water, it will also collide with the pipe wall to make a sound.

Solution: Drain the hot water from the radiator, clean the radiator, and remove the debris inside.

3. The inlet and outlet water volume is different. The difference in the amount of water entering and returning to the radiator will also make the radiator make a sound.

Solution: Adjust the water inlet valve and the return valve, and the water inlet and return water are not far apart.

4. The radiator rubs against the bracket. If the sound is like the sound of metal knocking, it means that it is not caused by water, but by thermal expansion and contraction, and the radiator is made by the expansion of hot water and the friction of the wall support.

5. The valve of the radiator is too small. The interface from the heating system to the radiator is not smooth, the heating valve is not fully opened or the opening is too small, and the valve produces a snorting sound, which causes the heating water to hit the pipe wall of the radiator and produce noise.

Solution: Replace the valve of the radiator.

Radiator due to replacement and other reasons, will cause noise, noise will not only affect the quality of people's rest, and even affect the mood, under normal circumstances, radiator noise mostly appears, the old building central heating single-pipe series system, the connection mode is mostly up and down, the new building is mostly parallel system, and the installation mode is down in and down, and the noise phenomenon is very rare.

There is air in the heating is also the reason why there are one or two pieces of not hot, sometimes the water flow in the radiator is uneven or there are debris washed out, and the water intake and return water of the radiator are not balanced will also produce sound, and the interface between the well-known brand system of the heating radiator and the radiator is not smooth, the heating valve is not all open or the opening is too small, and the valve produces a sneering sound, which causes the heating water to impact the pipe wall of the radiator and produce noise.

Under normal circumstances, there are two main reasons for the sound caused by the debris in the radiator, one is that there is slag or plugging cover during welding, and then the impurities in the heating system sand enter the radiator to precipitate, and the sound is washed by the water flow.

Then open the water inlet valve, open the air above the radiator, turn off the air after all the air in the radiator is released, and then slowly twist the water return valve until there is a sound and then go to the ** section, until there is no sound.

AnswerThere are many reasons why radiators are loud, and there are different ways to deal with them, so we should find the cause first, and then take appropriate treatment methods to deal with it, as follows:

1. The sound of the radiator is most likely caused by the accumulation of air in the heating system. If air accumulates in the heating system, the heating system will not be filled with water, and the water in the radiator will naturally make a noise when it is running.

Solution: At this time, the inlet valve and return valve of the radiator should be closed, and then the exhaust valve on the radiator should be opened with a screwdriver to let the air in the radiator be discharged. When there is no air in the exhaust valve or the water is discharged again, open the switch of the water inlet valve for water injection, and at the same time observe the exhaust situation of the exhaust valve position, when the water flowing out of the exhaust valve becomes smooth, you can close the exhaust valve and open the return valve.

There are many reasons for the sound in the radiator, among the many sounds, the sound of "lalala" running water is the most common, and this problem is mainly caused by the air in the heating. The first step is to open the air release valve and deflate until the air is exhausted. This first step is able to solve about half of the sound rate.

After deflating it is still there and screaming tirelessly, what to do? This is caused by the inability to clean the gas inside. In this case, it generally appears in the installation method of bottom in and out or bottom in and out, and the solution is to replace the upper plug to change to running wind, that is, the left and right sides of the upper side are running wind, and when deflating, the left and right running air are opened at the same time, which can generally solve this problem.

Heating radiator, easy to run and noiseless!

There may be some reasons for this:

1. The circulating pump needs to be turned on once the heating is supplied and turned on, and the sound is very loud.

2. A filter is installed in the household registration in some places, and the sound of water impact is also very strong.

3. It may be that there is gas in the heating pipe, causing the water to circulate and collide with the sound solution

You can open the valve on the radiator head (pay attention to open it slowly, don't open it too much), put a basin under the valve, just put some water, listen to it again, if there is still a sound, put it again until there is no sound. Judge the position according to the sound, turn on the running air and deflate.

There is air and debris inside the ducts. If there is air in the heating pipe or the air is not clean, it will cause the sound of running water;

2.All you need to do is turn the exhaust valve out of the excess air. If it is because of the debris entering the pipe and being washed by the water flow;

3.The heating pipes need to be cleaned at the end of the heating period. In addition, the heating system interface is not smooth, and the water inlet and return water are uneven, which can also cause the heating pipe to ring.

Heating radiator, easy to run and noiseless!

1. The filter is blocked.

If the noise is recent, check the filter first. A clogged filter can cause the fan to draw in air from anywhere, even a tiny hole, and if a large amount of air is sucked in, it will whistle. To determine if this is the cause of the noise, simply pull out the filter and see if the whistling stops.

2. There are gaps in the pipeline.

Try to listen to the noise coming from **. It is possible that it is a small hole, located near the blower, where the pipe is connected to the furnace. To solve this problem, you can seal the gap with aluminum foil tape, duct tape or high-temperature silicone.

3. The air duct is too small.

If neither of the above problems is left behind, and once the heating door is opened, the noise is gone. Explaining that the pipe size may not be suitable, opening the furnace door releases some of the suction, and the heating stove actually needs a larger air flow.

When the pump is installed, a shock-absorbing rubber pad should be placed at the foot;

The axis of the motor should be consistent with the axis of the pump and should not be skewed, otherwise it will cause vibration;

Check whether the parts of the pump are worn out, which is also the cause of the sound;

Noise can be reduced by adding a soundproof cover to the pump.

1. Close the return valve on the radiator, then use a screwdriver to open the air release valve of the radiator, release the air inside, and then close the air release valve until the water in the pipeline is unobstructed.

2. Check whether the return valve of the radiator is fully opened, or whether the open hole is particularly small, and then adjust the water inlet and return water to a balanced position.

The specific situation is not clear, because it should be the premise resonance of the pipeline, I personally suggest that the pipe hole through the wall be enlarged and re-closed with pull back glue or foam glue, which is to solve the resonance between the pipe and the wall, which can reduce the noise.

This design itself is flawed, and it is hoped that the relevant departments will have other plans to put the main pipeline.

It should be caused by unqualified installation, upstairs is right, the way is to reduce the noise,

This kind of noise is normal.

This year's newly replaced heating equipment is unbearable for the noise. Not sure if the heating company can solve it.

The Beijing Morning Post reporter called the **** of the heating group, and the staff said that the project is the heating group in accordance with the requirements of coal cleaning and nitrogen reduction, the existing old, long-running boiler equipment will be replaced, further reduce environmental pollution, and improve the quality of heating. In addition to the renovation of the heating equipment, the focus of the project also included noise reduction treatment. On the premise of ensuring the heating requirements of residents first, various technical means will be used in the follow-up project to gradually improve the noise problem.

In addition to the placement of acoustic panels, other auxiliary measures are being gradually implemented and in a few days, residents should be able to feel a noticeable change. "We are doing our best to reduce noise, and we believe that it will be effective soon."
