How to solve the sound of the main heating pipe

If there is a sound in the main heating pipe, it may be that there is air in the pipe or impurities in the pipe water, and it is necessary to do exhaust or clean up the impurities. The sound of the heating pipe may also be due to the uneven inlet and return of the radiator, just open the inlet and return valves completely.

The sound of the heating main is caused by the rapid flow of water in the pipe, the presence of air in the water, the vibration of the pipe, etc., and there is a corresponding solution for each situation.

If the flow rate is too fast, choose a low-speed water pump; There is air in the water, and an automatic exhaust valve is installed at a high level; The pipeline vibrates, flexible joints are set at the place where the inlet and outlet of the pump is connected to the pipeline, and fixtures are added to other pipelines.

Radiator. The sound may be due to thermal expansion and contraction.

Radiators are generally metal products, hung on the wall with metal brackets or hooks, hot water circulates in it when working, and there will be a certain degree of expansion after heating, which is affected by the surrounding environment and heating temperature, and is not so constant.

When the ambient temperature and heating temperature change, the radiator will produce a certain position offset due to thermal expansion and contraction, and the friction and noise with the contact bracket will occur, and even some radiators with thinner wall thickness will also produce a certain sound due to thermal expansion and contraction.

The noise itself makes a sound, we can only solve the problem by replacing the thicker radiator, for the noise caused by friction with the bracket, we can install a flexible gasket at the point where the bracket is in contact with the radiator.

For example, rubber gaskets, so that even if there is some movement because it is flexible, it will no longer make any noise, if the noise coming from the radiator is the sound of water flowing.

It may be because of the inconsistent opening of the inlet and outlet valves of the radiator The inconsistent opening of the inlet valve and the outlet valve of the radiator will lead to an increase in the local velocity of the water flow, resulting in the sound of the water flow, this sound is basically regular, there are foreign objects in the radiator, such as iron filings, sand particles and other hard foreign objects into some welding slag, will impact the pipe wall with the water flow, so there will be a certain sound, there is air in the radiator, there is a certain amount of air in the radiator, similar to empty, In this way, the water flow will also produce a certain sound.

What should I do if the heating room is too dry?

If the heating room is too dry, you can put a basin of water in the room, because the room only needs to increase the humidity a little, put a few basins of water in the corner of the room, and the water will slowly evaporate, which will naturally replenish the humidity of the air and make the room less dry, or keep a few pots of green plants in the room.

Hang a few wet towels, because when the environment is dry, these fabrics will also be easy to dry, and the moisture of the fabric will evaporate into the air, so the humidity in the room will rise, especially for families with radiators and air conditioners, this towel can be hung close to the heat source, and the evaporation will be faster, but hanging towels can not block the air outlet of the air conditioner.

As long as it does not affect the use of electrical appliances, it is better for families with severe indoor dryness or use floor heating, choose a humidifier.

It is also a must, because the humidification efficiency of the humidifier is very high, even if there is a humidifier in the environment, it is easy to make the environment moist, whether it is to breathe or ** comfortable, the humidifier can be selected according to the size and dryness of the room.

A small humidifier of that kind is enough for a small room, and the other thing is to drink plenty of water and breathe when the environment is dry.

It feels very dry, you can drink more water to moisten your throat, so that the water will make you feel a lot more comfortable, especially when you sleep at night, be sure to put a glass of water on the bedside table, you can drink it when you are thirsty, if your nose is uncomfortable, you can wipe your nose with a wet cotton swab to keep it moist.

1.The sound of the water flowing:

Phenomenon: When you hear the sound of "bang, bang", it means that there is a large amount of air in the heating system, and when the air and water flow at the same time, it will cause a local lack of water and underflow, so that the water flow will make a sound in the internal wall of the radiator.

Reason: When the cold water is heated, the air will overflow from the water, and if the system pipeline direction is more complicated, especially if many pipelines take a curve, it will cause air to accumulate at the elbow, resulting in this situation.

Solution: Install a precision decontamination device with an exhaust valve on the output line of the pump.

2.Resonant sound:

Phenomenon: The radiator makes a "buzzing" sound that is endless, especially in the dead of night.

Reason: The radiator fins resonate with the frequency of the pump and the system, which makes the radiator fins vibrate continuously and make sound.

Solution: All radiator mounting brackets must be fitted with nylon damping gaskets at the radiator hooks, and the pump gear should be lowered when the head is sufficient.

3.Whistle sound:

Phenomenon: The inside of the radiator emits a whistle-like sound, which is relatively high-pitched.

Reason: The local flow rate of the radiator is too fast, and the inner wall of the radiator is quickly washed out and makes a sharp sound, which is often because the radiator is installed with a temperature control valve, and when the temperature of other rooms reaches the set temperature, the radiator has been closed, and only one or two groups continue to work, resulting in the situation that the flow rate is too fast.

Solution: Turn the pump down one gear if the system head is sufficient, or install a differential pressure bypass valve at the inlet and outlet.

We all know that when we use radiators at home, we will hear some sounds coming from the radiators when we are heating normally, what is going on? It may be due to the following reasons:

1. The water flow in the radiator is uneven.

Second, there is debris in the radiator.

3. There is air in the radiator.

Fourth, the heating is hot.

Fifth, pressure. The sound of the radiator will not affect the normal use of the radiator. If there is a sound in the pipe, it is generally that the pipe is not fixed and shaking.

1. It is mainly caused by the uneven flow of water in the radiator or the debris being washed, and the sound caused by the debris in the radiator is mainly caused by two reasons, one is that there is slag or plugging during welding, and then the impurity sand in the heating system enters the radiator to precipitate and is washed by the water flow to produce sound.

2. It will also make a sound when the water inflow and water volume are not balanced.

3. The interface between the heating system and the radiator is not smooth, and the heating valve is not all opened or the opening is too small, and the valve produces a sneering sound, which may also cause the heating water to impact the pipe wall of the radiator and produce noise.

Solution: 1. Close the water inlet and return valves of the radiator tightly, then open the water inlet valve, and then open the running air above the radiator, and turn off the running air after all the air in the radiator is released.

2. Open the return valve, and adjust it appropriately when there is a sound until no sound is produced.

3. If the return valve is adjusted and the sound still exists, the user can open all the return valves and then adjust the water supply. The purpose of this is to balance the inlet and return flow of the heater, so that there will be no more noise in the heating after the water flow is balanced.

Why do radiators make sound during heating? Why do radiators keep ringing? What causes the noise in the radiator?

Why do radiators make noises? Why do radiators ring? What's the deal with the noise in the radiator?

What causes a ringing sound in a radiator? Why is there sound in the radiator?

It is normal that there will be a sound during the water supply period or in the early stage of heating, and the sound will disappear after the heating is stable.

If there is a violent noise in the pipe, affecting the rest of the residents, please call for repair** in time.

The content** is in the Fengtai District Heating Station.

Generally speaking, the radiator is silent when heating, and the radiator has a ringing sound, and there are 2 situations to check first! If left untreated, it can even destroy the heat dissipation of heating production.

Circumstance. 1. The volume of air is pressed in the radiator.

If a large amount of gas is accumulated in the heating system, the hot water will continue to hit the inner wall of the heating after the heating is connected to the heating, and a sound will be emitted.

Handling tips: 1. When the heating is first run and debugged and after later use, it must be exhausted, and the specific steps are to loosen the air release valve in the upper right corner, slowly exhaust, and close it if there is water splashing; 2. The heating installation should not be too high, which will cause other backlogs and difficult discharge.

Circumstance. 2. Impurities wash the heating system.

Small impurities such as sediment in the heating system will be washed into the heating by the waterway and hit the heating wall pipe, and there will be a gurgling sound. After a long period of congestion, the heat of the heating will also be problematic.

Handling tips: So the easiest way is to clean the heating thoroughly, pay attention to add a filter screen before the entrance valve pipe, which can also block a lot of impurities from entering.

In addition, it is important to pay attention to whether the heating is desoldered if there is a burst of noise from the newly installed radiator in your home.

Because some inferior heating welding is not firm, after long-distance transportation, resulting in de-welding between the fins and the waterway, once installed and used, the heating water flow will cause a sound, which will increase the hidden danger of water leakage in the long run. When purchasing, it is important to pay attention to the radiator welding process.

2. After using it for a long time, or when installing the radiator at the beginning, the worker drops the cinder in the heating pipe, or there is a gap at the interface, which will cause impurities to penetrate into the pipe.

3. The water flow in the system is not particularly balanced, and there will be a squeaky sound at the valve, mainly because of the problem caused by the heating water hitting the pipe wall.

4. Another reason is thermal expansion and contraction, such as the temperature rises after turning on the radiator, and it will rub against the installed bracket, which will make a sound.

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.

Why does the radiator have sound during the heating period?

Winters are cold in the north, and most homes are heated. However, some people use Chang Tangerine to react that their heating pipes will make a noise, but it is not very obvious during the day, and in the quiet night, the noise will affect sleep. So why do heating pipes rattle?

What to do? Let's take a look at the relevant knowledge.

1. The reason why there is a sound in the radiator.

There are many factors that make the sound of the heating socks, such as the uneven flow of heating water or the presence of gravel and other debris in the pipe, because when the heating water circulates in the pipe, the impurities will be washed and the sound will be generated; If there is an imbalance between the inflow and return water, it will also cause noise; If the heating system connections are not smooth, or if the valves are not fully open or the openings are too small, the valve will also make a snorting sound, causing noise from the pipe wall.

2. What should I do if the heating pipe makes a noise?

As long as you adjust it yourself, the way is very simple. First close the heating inlet and return valves, especially the return valve, remember to close the water, then open the water inlet valve, find the exhaust valve above the radiator to ventilate, when you hear the sound of puffing, after a while the heating water will flow out and stabilize, and then close the exhaust valve, and finally open the return valve, so that there is no sound in the general pipeline.

If there is still a sound after the backwater is adjusted, the backwater can be turned on to adjust the water supply. If there is still a sound, you can balance the backwater, and when the water flow is balanced, it will not wash up the debris and cause the noise. When we adjust the radiator, we should pay attention to the fact that it is best to adjust the two valves together.

Conclusion: Radiator sound is a common phenomenon, there are many reasons for the sound of heating, if there is a sound problem, do not worry, use the warning and the above measures to solve the problem, if you are not very clear about the way of operation of friends, or please professional radiator after-sales service personnel for maintenance is more reliable.
