Where are the common water leaks in radiators?

1.Due to the process, the radiator head and the cylinder are welded together, not as a whole, and the solder joints are the most likely to be corroded. In this problem, the manufacturer's solution is to continuously improve the welding technology and strengthen the internal anti-corrosion treatment, and you need to choose a radiator with a high-quality internal anti-corrosion coating when choosing a radiator.

In daily use, you should pay more attention to the opening part, and if you find any damage, you should hit the manufacturer in time and deal with it in time.

2.The various connection points of the radiator contact heating system are very easy to leak water, including the connection points between pipes, the connection points between pipes and radiators, and the air running and plugging. These connection points are in constant contact with water and air, and materials of slightly inferior quality will slowly corrode, causing water leakage.

When selecting materials, you should pay attention to the quality of the pipe and the quality of the radiator accessories, and replace the accessories in time in case of water leakage.

3.The water leakage of the radiator pipe wall heating radiator pipe wall is generally caused by accidental damage, and the damage here needs to be repaired in time to avoid greater corrosion.

Leakage at the radiator connection.

2.Radiator trachoma leaking.

3.The radiator exhaust valve is broken and leaking.

4.Leaking water from the wall of the radiator pipe.

5.The radiator burst and leaked.

First of all, check whether the radiator is cracked or corroded. If these signs are present, some remedial measures must be taken to avoid damage caused by installation or collision. Secondly, if the leakage is not serious, it can be repaired by soldering to repair the leakage and repair the old liquid leakage.

Then, see if the radiator drain switch is leaking. If the outer tube is damaged a little, remove the heat sink and repair it. Finally, if it is very urgent, you can use butter and cotton sticky to plug the leak evenly.

In the use of automobiles, it is common for radiators (water tanks) to have insufficient water, and many places are damaged and leaking. A common failure of radiators is leakage, which is mainly caused by corrosion, perforation, and mechanical damage. The engine overheating caused by the damage of the radiator, the failure of the water seal of the water pump, and the leakage of the loose joints of the upper and lower water pipes should be repaired separately.

Special attention should be paid to the leakage of the core tube of the water tank due to bumps, deformation, damage and disassembly; The installation position should meet the requirements of the original factory, so that it can be kept at a certain distance from the fan blades to avoid collision and friction during operation. During use, pay attention to check whether the front of the core of the water tank is blocked by weeds and dirt, and clean it if necessary, so as not to affect the heat dissipation performance and avoid scraping the core pipe during operation.

Pay attention to check and ensure the accuracy of the cone surface fit of the pulley and the taper sleeve. The taper of the pulley taper hole and the taper sleeve should be consistent, after the taper sleeve is pressed into the taper hole with the thumb, the small end of the taper sleeve is required to be lower than the end face of the taper hole of the pulley 2 3mm, and the taper surface is in good contact. Check that the pulley is really pressed after the shaft end fastening nut is tightened, and adjust if necessary.

The shaft end nut of the pump shaft should be specially tightened, the tightening torque should meet the requirements of the technical specifications, it should be checked and maintained frequently in use, and the loose nut of the water tank foot should be tightened in time. If the fan blades are cracked and deformed, they should be repaired or replaced with new parts in time. When the screws of the engine legs are loose and the whole machine moves forward, it should be repaired.

First, the leakage at the interface is caused by the fittings. This is the more common scenario. Due to unprofessional installation, or the purchase of substandard accessories, during use, the accessories are slowly corroded, which eventually leads to water seepage and even water leakage.

In this case, it is only necessary to replace the accessories. By following the operating procedures and using the original parts during the installation process, consumers do not have to worry about leakage caused by the accessories.

Second, leakage caused by corrosion. Many consumers have encountered this problem, especially radiators that have been used for more than 10 years, and the chance of corrosion is higher. In this case, you should first contact the manufacturer to see if there is a warranty period, generally the warranty period of steel radiators is 5 years, and the service life of the radiator is much higher than this standard.

If the warranty period has not passed, contact the manufacturer for free replacement, even if the warranty has passed, consumers should not worry, they can contact the manufacturer to consult solutions.

Third, leakage accidents caused by human factors. The radiator will inevitably be bumped in the room, especially the collision of sharp objects on the radiator. If the leakage accident of the radiator is caused by human factors, the water inlet valve should be closed in time and the maintenance personnel should be called immediately to solve the problem.

1.Water leakage due to radiator mounting design issues.

The installation of radiators is not an easy task, and it needs to be carefully designed and constructed by professionals, and an unreasonable setting of a detail will affect the use of heating or lead to water leakage. From the decoration level, the heating installation belongs to the construction of the waterway, if the interface between the heating and the pipe is not properly handled, and the inferior accessories are used in the installation, it will lead to the connection is not tight, the valve is wireless, and thus causes water leakage.

2.The heating water quality is complex or the radiators are mixed.

The water quality status in various parts of China is different, and the heating water quality in many areas is more complicated. Some areas belong to alkaline water quality, the oxygen content in the water is high, if the steel radiator is used, it is easy to cause the radiator oxidation corrosion, resulting in water leakage and bursting accidents. In addition, the mixing of radiators of different materials is prone to electrochemical corrosion, which can easily lead to problems such as water leakage of radiators.

3.Improper maintenance of the radiator leads to water leakage.

In the non-heating season, some heating radiators should be full of water for maintenance, otherwise it is easy to bury hidden dangers. Copper-aluminum composite radiator manufacturers pointed out that in the non-heating season, emptying the water in the heating system will lead to accelerated corrosion of steel radiators, boilers, water pumps and valves, and will also block radiator temperature control valves, heat meters and other products.

If you look at the leakage point, you should know the reason, the interface is not well handled, the vibration caused by wear and tear causes cracks, the question between the splice and the piece, the loosening of the wire, etc., may cause water leakage.

In the early stage of heating, be sure to check whether the heating system has run, rising, dripping, leakage and other water leakage, such as finding that there is a slight water leakage phenomenon in each heating town, do not worry, under normal circumstances, the dripping phenomenon within two seconds is normal, the water outlet is because the hemp at the key thread interface is not opened, and the water seepage phenomenon will disappear after normal heating. If the water seepage is more serious, the user needs to find a professional for maintenance, and cannot disassemble it privately to prevent more serious situations.

If the heating radiator is missing due to quality problems, the user should contact the manufacturer to solve the problem and repair or replace it. This situation rarely happens in well-known heating radiator products, and it is more common in some small workshops to make products than royal makeup, which is one of the reasons why most users choose well-known brands.

Heating starts in winter, and in case the radiator leaks, it will affect the room temperature. With more than 20 years of experience, Beijing Paijie radiator experts will teach you 3 steps to deal with radiator leakage accidents in a timely, effective and calm manner, and minimize potential losses.

Step 1: Make a note of the leak and quickly close the heating valves.

Usually, there is a locking valve at the connection between the inlet and return pipes and the radiator of each group of radiators, which is used to shut down the group of radiators during maintenance or overhaul. If a certain group of radiators has a large leakage, the control valve of the leaking radiator should be found, and the valve should be rotated clockwise until it cannot be screwed, so that the group of radiators will be turned off.

It should be noted that the design of the radiator heating system of new buildings is usually double-pipe parallel, and the advantage of this heating system is that shutting down a certain group of radiators will not affect the normal heating of the radiators in other rooms. However, if it is a series heating system, it should be noted that after the first set of radiators is turned off, it may affect the heating of radiators in other rooms.

There are more old-fashioned heating systems, the whole building shares a master valve on each floor, and each group of radiators does not have a locking valve, to turn off the leaking radiator, you need to contact the property or heating company in time to ask it to close the main valve, do not turn it off privately, otherwise it will affect the normal heating of the users on this floor. However, the number of such heating systems is very small.

For a small amount of gaskets, joints, and small leakage of sand holes, a larger container can be used to connect the water in an emergency to avoid soaking the ground, and the radiator can still be heated normally. However, the third step mentioned in this article must be taken immediately, and it is absolutely necessary not to compromise in order to prevent the leakage from becoming larger and causing greater losses.

Step 2: Emergency heating.

If the leaking radiator is turned off, the room temperature will quickly drop and will soon fall below the minimum temperature requirement of 16-18 degrees of the national standard. If you still want to live in this room, you should take emergency heating measures such as electric heating, air conditioning, and extra clothes or bedding to avoid freezing and cold.

Step 3: Analyze the cause of water leakage and repair or replace it in time.

Check the specific location and location of the radiator leak and take different maintenance measures to ensure safe and reliable heating.

1. If there is water leakage at the radiator interface, you can consider replacing the radiator union, or adding fine hemp rope to re-winding to increase the sealing.

2. For cast iron radiators, if there is water leakage at the wire connection, please ask the manufacturer or professional plumber to replace the wire or gasket, and there is no need to replace the whole group of radiators.

3. For cast iron radiators, if the radiator is leaking due to sand holes, only the radiator needs to be replaced, and other pieces can also be used.

4. For steel, aluminum or copper radiator leakage, usually because of age or corrosion, as long as there is a leakage point, it is necessary to replace a group of newly processed radiators, it is best not to repair welding.

5. The radiator installed after re-repair must be re-pressed and tested to ensure that there is no leakage.

The third step should be carried out by a professional plumber or someone with practical experience.

What to do if the radiator is leaking? It is easier to solve it by following the above steps.

The emergency solution for radiator leakage is to sprinkle a little fine sawdust into the circulating water and deal with it to the repair station;

If you want to be thorough, you must remove it and plug the leakage point with solder, there is no special good way.

If you have a small problem, you can use the two brothers to stick it, and if you have a big problem, you have to call a maintenance worker.

When you go to a 4S shop or repair shop, you need to look at the specific part to determine whether to weld or replace.
