Why does the boiler have a recirculation pump, and what is the matter with the old circulation of th

Hangzhou Boiler Plant Manual:

The recirculation system of the boiler is set up to avoid the economizer temperature being too high. To put it simply, it is to protect the economizer, usually when the boiler is not in water, the economizer recirculation pipe must be opened!

There are 2 types: boiler circulating self-heating; The pipe circulates and is hot when it is opened.

Bring the energy inside the boiler to the system.

The boiler circulating pump keeps circulating, what's going on? To tell the truth, after the situation, I don't like to stop it all the time, then it's a problem, and if I dismantle the electric circulating pump, he is a water cycle, and she's like this, who do you let in? How?

Right? How do you get inside the corner? How can it be hot?

The heating is safe on the cover of the class, so if Tian Hua has a failure, he won't be able to hear the failure, does he like you? It's just a constant cycle, and the water he throws out will cool it back, and then it will be hot, and then it will be sent out later, that's the reason.

Summary. After the Padi boiler stopped heating, the circulating pump ran for another 2 minutes before it stopped. After the circulating pump stops, the timer reaches 20 minutes, and the circulating pump runs for another 1 minute.

After the Padi electric boiler stopped heating, the circulating source silver pump ran for another 2 minutes before stopping operation. After the circulating pump stops, the timer is 20 minutes, and the circulating pump lacks Zen and transports hail for 1 minute.

The circulating pump can be left on all the time. The circulating pump can be continuously opened for a long time without any problems. However, in order to ensure the service life of the circulating pump, if you want to make the circulating pump last longer, it is recommended to turn on the closed position during the day and turn it off when you sleep at night.

The temperature demand is not very high when you sleep at night, so it can be turned off. The same is true for the circulating pump, which can be used for other purposes, and can be stopped for a while and then turned off. Although the circulating pump will not break if it is always on, it will have an impact on its life.

The service life of the machine is determined by the use time, if it has been turned on, it will definitely speed up the service life of the circulating pump, if in a high temperature environment, the circulating pump has been working for a long time, it will be easy to make the circulating pump machine have problems, and it is possible to burn out the motor.

It may also be that there is a problem with the set program, and the temperature differential controller switch is faulty.

There are connecting pipes at the interface of the boiler and the circulating pump, and the user can directly connect the interface connection pipes of the two through the water pipe.

A circulating liquid pump for transporting reaction, absorption, separation, and regeneration of absorption liquid in a circulating pump device. Generally, a single-stage centrifugal pump is used. The flow rate of the circulating pump is medium, and the flow rate of the pump changes relatively little under stable operating conditions.

It has a small and low head and is only used to overcome the pressure drop in the circulatory system. Low-head pumps are available. The circulating pump refers to the role of the pump, and the centrifugal pump refers to the structure of the pump, and the two are completely two concepts.

The working principle of the circulating pump is to circulate the water, and the pump used is called the circulating pump, for example, the hot water in the plumbing and heating pipeline is circulated by the circulating pump.

Glad to be able to answer for you :

It's self-cycling. The lower the temperature, the longer the cycle time of the circulating pump. For the heating system, there are generally three circulation methods:

First, when the water in the tank reaches a certain temperature, the circulating pump starts.

Second, when the return water temperature is lower than the set value, the circulating pump is activated.

Third, when the indoor ambient temperature is lower than a certain value, the circulating pump will be automatically started.

The first type of circulation has little to do with temperature. Clause.

Second, the third type of circulation has a lot to do with temperature. When the temperature is low, the heat dissipation intensifies, and the return water temperature cools down quickly, so the cycle will start frequently or even keep circulating.

The boiler circulating pump is used to force the circulation of hot water in the boiler to improve the heat transfer effect, and it needs the characteristics of heat resistance, large flow rate and low head. The boiler feed pump is used to replenish water for the boiler, which requires high head and small flow, and is generally a multistage pump.

Hello, normal, In fact, as far as the question of can the circulating pump work all the time, it can work all the time, but it is not necessary. Because the main function of home heating and circulating pump sales is to speed up the water flow in the heating pipe, so as to increase the indoor temperature, generally speaking, as long as the temperature reaches a certain value, it can be turned off. In addition, even if you don't want to turn it off during the day, you can turn it off at night when you sleep.

Because, while sleeping, the temperature pants bucket smile has reached a certain value, so it can be turned off. Otherwise, if it is left open, it will affect the service life of the circulating pump.

Summary. Hello, it can not be installed on the return pipe, if it is installed on the return pipe, the water pump will transport the water of the system to the boiler, which will inevitably increase the amount of water in the boiler, so the pressure relief pipe will come out of the water. When the boiler is burned after the water pump is stopped, when the boiler water temperature reaches a certain temperature, the water hammer phenomenon will occur in the boiler, and the "cannon sound" will be generated.

Hello, it can not be installed on the return pipe, if it is installed on the return pipe, the water pump will transport the water of the system to the boiler, which will inevitably increase the amount of water in the boiler, so the pressure relief pipe will come out of the water. When the boiler is burned after the water pump is stopped, when the water temperature of the boiler reaches a certain temperature, water hammer will occur in the boiler, and the old mountain will be hungry and produce "cannon sound".

Does the circulating pump of atmospheric boiler installed in the return water have any effect on the boiler?

There will be an impact.

The new boiler is leaking, is it caused by the circulating pump installed in the return water?

Hello, yes, it is caused by the installation of a circulating pump in the return water.

The boiler explosion-proof plugging is broken, can it be blocked directly?

No, the explosion-proof valve is a safety device to prevent the internal pressure of the boiler from being too high, once the pressure is high after blocking, the pressure has nowhere to go, and there is a danger.

In the case of ventilation at the atmospheric communication port, can the explosion-proof be blocked and blocked?

Can be blocked.
