What is the small water pump on the heating pipe for?

The water pump plays the role of forced circulation. The flow rate of water in the pipeline is accelerated, so as to increase the heat exchange speed and improve the heat exchange effect.

Without a water pump, for a system with long pipes, the temperature difference between the radiators in front and back of the pipe system will be too large due to the difference in distance from the heating furnace.

The upper part of the radiator is very hot, and the lower part is average, which indicates that the heating heat source is insufficient, and the water circulation is slow to exchange heat. The reason is that the heat exchange mode of water is convection, the specific heat of hot water and cold water is different, hot water is lighter than cold water to float, cold water sinks, heat ** is insufficient, water circulation and exchange is slow, water stays in the radiator for a long time, and the contrast effect is obvious, this phenomenon occurs.

This phenomenon can also be caused by installation reasons, such as the installation position of the water pipes at both ends of the radiator, and the uneven heat distribution of the radiator is easy to occur in the high-in-low low-out type. Therefore, most of them now use the low-in, low-out type.

Solution, 1, improve the heat output of natural gas heating water furnace.

2. Turn on the water pump under the premise of 1 to increase the heat exchange speed of the radiator. Note that the water in the system should be saturated.

The water pump on the heating stove belongs to the circulating pump, its function is to speed up the circulation speed of the medium in the pipeline, so as to reduce the temperature difference between the upper and lower parts of the radiator, and the upper part of the radiator will not be very hot after the installation of the circulating pump, and the lower part is in general! Of course, this increases the operating cost of heating, and if it is not used, it can reduce the electricity consumption of the pump, which means that this part of the energy consumption is saved!

I don't know if I'm so concise! Hehe!

Pressurization increases the overflow in the radiator, of course, it increases the temperature of the radiator, increases the temperature difference between the radiator and the indoor air, and increases the heat dissipation.

OK. If the natural circulation is maintained, then the circulation pressure of the system will be relatively large, and a small bubble in the system will have a great impact on the circulation of the system. After installing the circulating pump, the installation of the heating is much easier, and there is no need to worry about the lack of pressure.

If it is a natural cycle, then in order to make the circulation of the system have a certain pressure, the radiator and the boiler must keep some distance, not too close, so there will be some families in the forest hand boiler installed underground, and the radiator hanging very high. And after installing the circulating pump, you don't have to worry about these problems.

The use of the small water pump on the heating pipe is as follows: the water pump on the heating stove belongs to the circulation pump, its function is to speed up the circulation speed of the medium in the pipeline, so as to reduce the temperature difference between the upper and lower parts of the radiator, and the upper part of the radiator will not be very hot after the installation of the circulating pump, and the lower part of the general situation! Of course, this increases the operating cost of heating, and if it is not used, it can reduce the electricity consumption of the water pump, that is to say, it saves this part of the energy consumption, and the installation method of the earth heating furnace is as follows:

1. The heating stove cannot be installed in the bedroom or the room directly connected with the bedroom to prevent gas poisoning. 2. A pressure reducing pipe should be installed at the outlet of the heating furnace. Its diameter should not be less than the diameter of the pipe.

3. The inlet and outlet are connected by live connection, which is convenient for maintenance. 4. The slope of the main pipe should be 100:1 in the horizontal case, which is conducive to exhaust.

5. The highest part of the water supply pipe of the coal-fired heating furnace should not be higher than 6 meters of the furnace return port, otherwise it will lead to excessive pressure and deformation of the protective body. 6. The expansion tank needs to be installed in the system, and the height of the water tank should be more than 250mm at the highest point in the system. 7. It is strictly forbidden to install valves on the pressure reducing pipe, exhaust pipe and water supply tank, otherwise it is very dangerous.

8. The height of the center of the radiator should be more than 300mm higher than the center of the inlet and outlet of the furnace body. 9. When the circulation is not good due to non-obstructive reasons such as too long pipeline, the difference between the heating furnace and the radiator can also be further increased to promote water circulation, otherwise a small hot water pipeline pump should be added to force water circulation. Do not install the pump on the lower horizontal main to push water to the furnace, as the pressure of the pump will swell the stove.

10. Vertical chimney height: briquette furnace should be more than two meters, loose coal furnace must use a chimney with a diameter of 120mm, should be more than four meters, the chimney should be capped, and it is best to remove the chimney in summer. Hope mine can help you <>

Do you have any other questions?

1. Before the installation of the household heating water pump, check whether there is any foreign matter blocking at the inlet and outlet of the circulating pump;

2. Before the heating water pump is loaded into the system, the debris in the system pipeline should be flushed clean, so as to avoid the sundries winding around the impeller during the operation of the circulating pump and causing blockage;

3. When installing the pump, the force should be gentle, do not use force, so as not to damage the pump body;

4. The inlet and outlet of the household heating pump should be equipped with any of them to facilitate assembly and disassembly;

5. The safety wiring of the heating pump should be connected with a three-strand plug with a cluster and a ground wire, and the ground wire end should be connected with the motor shell to ensure safety;

6. The noise of the heating pump is low, and when checking whether it is rotating, you need to use a screwdriver to hold your ears and listen carefully.

Installed between the hot water outlet of the heat source and the inlet of the heating hot water pipe. The heating pump for home use is basically smaller, because the heating is a closed cycle, but it is necessary to consider the resistance along the way and the local resistance. The general family has 25 6, 25 8 circulating pumps are basically enough, and then a larger system, choose a pump with a flow rate of 2-3 cubic meters and a head of about 6-9 meters.

Generally, the purpose of setting up pipeline pumps is to solve the problems of insufficient pressure in the primary network, too small pressure difference, too slow flow rate, and too large resistance. Since the heating system is a closed-circuit cycle, there is basically no flow problem.

If the heat source terminal is too far away from an exchange station, the heat exchange efficiency can be low due to high resistance and slow circulation, in which case a pipeline pump can be installed at the exchanger inlet. If a certain hot area is too far away and the operation is not ideal, it is best to set up a pipeline pump, it is best to add it to the return water.

Hello, we are happy to answer for you how to distinguish between the inlet pipe and the outlet pipe of the warm ballast bright gas pipe pump.

1. How to distinguish between the inlet pipe and the outlet pipe of the heating pipe 1. If the inlet pipe and the outlet pipe of the heating are on the same side, then the upper one is the inlet pipe and the lower one is the outlet pipe. 2. If the water inlet pipe and the outlet water pipe of the heating are wide on both sides, and the place where they are located is diagonal, then the upper one is the water inlet pipe and the lower one is the water outlet pipe. 3. If the inlet pipe and outlet pipe of the heating are on both sides of the heating, and the place where the two valves are located is on the same straight line, we can judge by the number of radiators.

4. We can also touch the two pipes under the corresponding protective measures, and the low temperature is usually the outlet pipe.

The pro-heating circulating pump is installed on the return pipe, and the circulating pump can be installed in the inlet pipe and the return pipe, usually installed in the return pipe. When using the same type of circulating pump, the circulating pump installed in the return pipe flows faster. 2. The working principle of the circulating pump:

The water is circulated, the hydraulic oil is filtered and cooled in the hydraulic system, and it is circulated repeatedly, for example, the hot water in the plumbing and heating pipeline is circulated by the circulating pump. The function of installing in the return pipe: 1. Usually the temperature and pressure of the water supply pipeline are relatively high, and the temperature and pressure of the return pipe are low, so it is best to install the floor heating circulating pump in the return pipe to ensure the normal operation of the circulating pump.

2. The temperature of the return pipe is lower than that of the inlet pipe, and if the floor heating circulating pump works in a high temperature environment, it will damage the parts in the pump. 3. The circulating pump will reduce the cavitation allowance of the circulating pump in a high-temperature environment, and the water will be vaporized if the temperature is too high, which will cause the circulating pump to not be able to pump water, and it will also affect the service life of the circulating pump.
