What s the problem with the abnormal heating noise? What is the reason for the abnormal sound of the

The reasons why the radiator rings are as follows:

1.If there is air in the heating pipe, the water in the pipe cannot be filled, so noise will be generated during operation. At this point, before opening the exhaust valve, first turn off the water heater's feed and return pipes.

Then, turn on the water inlet of the water heater and let it return to its original position. When the pressure relief valve has drained the water, the exhaust valve is closed.

2.If there is a lot of debris in the heating pipe, there will be a noise when it is flushed out. Debris in the pipes can be dust from the welding process or grit from the heating equipment.

The radiator should be disassembled, cleaned from the inside, removed from the internal impurities, and restored to its original state.

3.If the heat sink expands and contracts coldly, it will cause the heat sink to collide with the metal bracket, resulting in a loud sound. Check that the keys of the heatsink are strong, if not, tighten them immediately and tuck the appropriate thickness of paper between the heatsink and the bracket.

If the pendant size is not the same, it must be reassembled.

It shouldn't be a big problem, it may be that the blades of the fan hit the object, look at the air inlet, whether the net is not installed and enter through this opening.

In this case, there may be gas in the heater and it needs to be vented.

Method 1: Close the water inlet valve first. Open the running air bleed valve to exhaust, there is water overflowing, close the air release valve.

Method 2: Close the water inlet valve 3 4, and then close the return valve, open the valve to exhaust, and half-close the air release valve when there is water overflow.

It is mainly caused by uneven water flow in the radiator or debris being washed.

If there is an abnormal sound when the car heaters turn on the heater, it may be that there is a foreign object on the heater that causes the blades to rotate and produce abnormal noise. It could also be a lack of lubrication or damage to the fan bearings. At the same time, it can also be due to resonance caused by hardening and embrittlement of parts caused by low temperatures.

The last reason is the dynamic balancing of the fan blades.

The iron is not adjusted well or falls off and <>

The solution to the abnormal sound of turning on the heater is as follows:

1. Check the blower and air conditioning system.

If there is a foreign object inside, such as leaves, plastic packaging, etc., it will make a similar sound, and the abnormal sound will disappear after being removed in time.

2. Check the bearing of the fan, add lubricating oil or replace the new bearing in time.

3. We don't have to deal with the problems caused by the abnormal sound of the hardening of plastic parts. All you need to do is turn on the heating for ten minutes, let the plastic heat up, and the noise will disappear.

4. Go to the regular maintenance shop to let the master adjust the dynamic balance of the wind blade. If the balance weight falls off, it should be reinstalled in time.

5. The air conditioner pulley and belt slip, there will be a sharp friction sound during the slipping process, check whether there is oil on the belt, if it is oil, make the belt slip clean. If not, you need to adjust the position of the compressor bolt so that the compressor belt is tight, which can increase friction.

6. If the belt is loose and makes an abnormal noise, you can press the belt by hand. If the belt is too loose, it needs to be replaced. If the belt tensioner is damaged, there will be an abnormal sound, and a new tensioner needs to be replaced.

7. The slippage of the compressor clutch will also produce abnormal noise, or the compressor bearing will produce abnormal noise, and it needs to be removed to check what the reason is.

8. Foreign matter entering the blower and respirator will also produce abnormal noise, and the blower and respirator need to be cleaned.

The fault of the general sound in the car is judged to be the problem of the blower, and the abnormal noise outside the car is judged to be the fault of the pulley or compressor. Generally, this kind of squeak and squeak problem is not a big problem, but it is not recommended that we replace or adjust the parts by ourselves. Because the air conditioning system in the car is still more complicated, if you are not familiar with the disassembly steps, if the internal parts of the air conditioner are damaged, it is best to go to the 4S shop for repair, and accidentally damaging other parts will increase the loss.

It is possible that the heater of the car is broken, so when this happens to the car, you must send the car to a professional car repair shop for repair, and only by doing so can you solve this problem.

It may be that the bearing is short of oil, so there is no way to operate normally, so there will be some different sounds.

This is caused by poor lubrication, but also because of the lack of oil in the bearing, and some lubricating oil can be applied.

Causes of radiator noise:1. Incomplete air emissions:

The air is not completely discharged, and the water in the system runs up to generate noise. Treatment method: You can close the water supply and return valve of the radiator trace, open the air valve until there is no air body released or no water flows out, and then open the water supply valve of the radiator until the water flows out smoothly, there is no water intermittent spray, close the air release valve, and then open the return valve of the radiator; If it is reversed, you can add an automatic exhaust valve to the automatic exhaust of the heating system.

2.There are two main reasons why the debris in the radiator is washed away: first, there is slag residue or the cover is blocked during welding; The other is that the impurity sand in the heating system enters the radiator and precipitates, which is washed away by the water flow to produce sound.

Solution: Remove the radiator, rinse the radiator and heating system, and then restore. 3.

Poor connection and connection: the interface between the heating system and the radiator is not smooth, the heating valve is not fully open or the opening is too small, the water inlet and return of the radiator are unbalanced, and the valve hisses, resulting in the noise caused by the heating water impacting the radiator pipe wall. Solution:

Adjust the water supply and return valve of the coin-operated gas radiator to balance the inlet and return water of the radiator. 4.Features of the radiator itself:

Because the radiator expands and contracts coldly, the radiator rubs against the metal bracket mounted on the wall to produce sound. Solution: If the radiator is not fixed firmly, you can stuff paper or mat with moderate thickness in the gap between the radiator and the metal bracket to solve the problem; If the pendant is not fixed firmly or unevenly, remove the radiator and re-fix the pendant to solve the problem.

In winter, radiators become the main equipment for heating many homes. However, there are times when the radiator makes an abnormal noise, which is very troublesome. So, what is the reason for the abnormal noise of the radiator?

First of all, the cause of the abnormal noise of the radiator may be the sound of the water. When the water inside the radiator flows too fast or too slowly, the sound of water flow is generated. This abnormal noise is usually caused by unreasonable pipe design or pipe plugging.

Secondly, the cause of abnormal noise of radiators can also be air noise. When there is a large amount of air in the radiator, airborne noise is created when the water flows through. This squeak and rattle is usually caused by a pipe leak, a water pump intake, or an imbalance in the system.

In addition, the cause of the abnormal noise of the radiator may also be the sound of metal expansion. When the radiator is heated, the metal material expands, resulting in noise. This abnormal noise is usually caused by the unsuitable material of the radiator or the poor manufacturing process.

Finally, the cause of the abnormal noise of the radiator may also be the scale noise. When a large amount of limescale accumulates on the inner wall of the radiator, limescale noise occurs when the water flows through. This squeak is usually caused by the radiator not being cleaned for a long time or the water quality is poor.

To sum up, the causes of abnormal noise of radiators may be varied, and consumers should investigate the causes in time and take corresponding measures to deal with them when they encounter this situation to ensure the normal use of radiators.

Many people feel that it is more convenient to use radiators for heating, so more and more families prefer to buy radiators, but after the radiators are used for a long time, there will be some minor faults, such as the radiators will make abnormal noises when heating, so what is the reason for the abnormal noise of the radiators? Today, I will explain the specific reasons for you.

1. What is the reason for the abnormal noise of the radiator?

First of all, it may be because there is a lot of air entering the radiator; The second is that the inside of the radiator is blocked by some foreign objects, resulting in the hot water cannot be automatically circulated; In addition, the heating valves may not be fully opened, or the openings of the valves may be relatively small. Because there are many reasons for the abnormal noise of the radiator, it is necessary to determine the specific cause before repairing.

Second, how to solve the situation of abnormal noise of radiators.

1. There is air in the radiator.

Open the exhaust valve of the radiator to let the sewage and air inside.

2. There are foreign objects in the radiator.

Stop using the heater first, and then ask a professional master to do a comprehensive cleaning of the radiator.

3. The heating valve bridge or not all opened.

Just turn the heating valve to the maximum by hand.

3. What are the advantages of radiators?

1. It is more convenient to install, and it is easier to maintain when there is a failure in the later stage, and the heating speed is relatively fast, from opening to reaching the predetermined temperature in the later stage, it only takes about half an hour to an hour.

2. There is no requirement for the ground and the elimination of only the paving materials and wall painting materials, and it will not occupy too much space, you can choose to install the radiator under the window, which will not affect the use or the beauty of the house.

Fourth, what are the disadvantages of radiators.

1. The temperature rises very quickly, so the comfort felt by the human body is not very good.

2. It must be installed in a place with air circulation, and at the same time, it must also take into account the situation of thermal expansion and contraction, after a long period of use, the wall surface of the radiator may appear yellow and black.

Radiators are very popular as common heating equipment in the home, so it has become more and more common to install radiators in house decoration. However, some users have recently reported that there is a sound in their radiators, which affects sleep at night, so what is the problem with abnormal noises in the radiators?

1. The uneven flow of water in the radiator or the debris is caused by scouring, 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 inflow and return of water flow are not balanced.

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

4. The system circulation is poor but the heat of the stove is large, or there is air in the return water.

The above is the reason for the abnormal noise of the radiator that I analyzed for you, and those who need it can understand it, I hope it can help you.

If there is an abnormal sound when the warm air is turned on when the car is cold in winter, and the abnormal sound disappears after the water temperature is normal, it is likely that there is a lack of oil in the warm front leakage motor. Solution: Disassemble and clean the heater and add some oil to it.

Some models are normal because of the thermal expansion and contraction of plastics.

If the water temperature is normal and the sound is still abnormal, it means that there is a problem.

The most common situation is that there is an abnormality in the blower.

Solution: Replace the blower.

Because you can't see the actual car, you can't make an accurate judgment, and you need to go to a 4S shop or a professional auto repair shop to let the technician check to be sure.

Identify the problem and fix it symptomatically.

Attached car heater introduction: The working principle of car air conditioning warm air and cold air is different.

The cold air of the car is based on the compressor.

Press the A C key, the compressor works, and the cold air is blown.

The heat of the warm air in the car is provided by the heat dissipation system of the car, and the heat of the warm air comes from the heat generated during the work of the engine, which is introduced into the car by a small fan, which is actually a "waste utilization".

In other words, in winter, you don't need to press the A C button to turn on the heater in the car, because there is no need for a compressor.
