How to install a circulating pump for heating ?

Species

circulation pumps circulating coolant pump creates a movement in any heating system.It accelerates the process of natural circulation by absorbing water and throwing it on the other side with greater force.Powered by an electric motor.

devices are divided into two types:

1. «dry».Its design is that it can not come into contact with water (or other coolant), as there in between sealing elements of corrosion (ring), which rotate at startup.They create pressure in the system, different from the external environment, which ensures tightness of connections.Dry motor efficiency - 80%.Very noisy.

Dry divided into three varieties:

• vertical (connections are on the same line, the installation is carried out in a vertical position);
• horizontal (suction pipe is the front of the device, and the second - on the housing is set in the horizontal position);
• block (coolant falls in a straight line, and goes into the circular).

For dry lubrication pump is important to have, because without it there is a big threat to the violation of his work."Wet»

1. .It the rotor is placed in the water, which serves for him as lubricant and coolant.Intrinsically presence of a special metal container, which guarantees the isolation of the electric motor and DC voltage.Efficiency - 50%, because the sleeve, located between the water and the stator is not sealed.Noise is much smaller.Excellent for household heating.

effectiveness of the device depends on the device the pipes themselves.In particular, one-pipe heating system constantly uses the coolant, and has almost no temperature extremes.Two-pipe system is characterized by exactly the opposite: using variable coolant and noticeable temperature drop.

Tools and materials to connect the pump

1. circulation pump
2. return valve
3. Filter
4. Ball valve
5. clutch
6. locknut
7. Keg
8. Thread «American»
9. Bypass
10. line tool set (screwdriver, hammer, pliers, etc.)

How to install a circulation pump in the heating system with their own hands

Before proceeding to the process of installing the device, read its instructions carefully.Basic principles of installation and connection on all models are the same, however, we should not forget that the device may have individual characteristics.

consider steps like mount types tsirkulyatsionnik in the heating system.

Step 1. Determine the location of the heating system to install the circulating pump

circulation pump should be installed on the return pipe directly next to the boiler.At high temperatures, water or other coolant service life of the pump will be reduced at times, and then repair or replacement required sooner.Also contained in the supply more air, which during operation will be accumulated in the device.On the device performance and location does not affect.

Step 2: Prepare the pump mounting location

boiler must be shut off and the pipe shut-off devices.Otherwise, the water from the system will have to be drained, it will take a lot of time and effort.Pipes should be allowed to cool in order to avoid injuries, and, if necessary, clean them.

Step 3. Creating a bypass pump

place when normal access is defined and prepared pipes, it is necessary to do bypass the organization (in other words, Bypass).With him when a malfunction in the device or failure, electricity heating system will not stop the operation, the coolant goes gravity.

It is recognized that the bypass pipe diameter should be slightly narrower than the diameter of the main pipe.

only after the end of the preparatory work can begin to install tsirkulyatsionnika threaded.

Note!To pump noisy not so much, it must be mounted in a horizontal position.If for the sake of saving space is necessary to install it in the vertical plane, be prepared for the fact that the noise will be amplified due to the construction of the instrument.

Step 4: Install the filter and check valve

These elements are optional, but are intended to extend the operating life and the ability to simplify its repair or replacement.In the open non-return valve and does not need a heating system, but with a closed experts strongly recommend its use.

Step 5. cutoff valves

last stage circulation pump installed in the heating system is to install a cutoff valve.Any system is much more durable than even the highest quality pump.Therefore it is necessary to prepare in advance the possibility of trouble-free access to the device, allowing it to carry out repair and replacement.

tsirkulyatsionnika After installation, the system is filled with water and vented air from it through a central screw.

Note!If the device is already in use will have some time off, the air need to pit again.
