Pumping Systems, circulation are used to support the movement of water coolant in businesses and private homes. Tasks can be different – from ensuring the basic functions of heating up of the organization advanced air conditioning systems. Directly circulation system is formed by several groups of communication elements, but the main link is almost always the pump.

Works

At a basic level heating infrastructure can assume the natural movement of the coolant. In this case, a Infloor schema, in accordance with which target objects heat generation Served the hot medium, and with the reverse side out exhaust cold streams. They again sent to Boiler, warmed up, and repeat the described cycle. This model is simple to maintain, but inefficient and is rarely suitable, for example, for two-storey buildings. In turn, circulating pump for heating allows to increase the power that in the end, Gives the possibility of uniform distribution at all points of heat distribution. That is, the radiators are installed on different floors, will be supplied with coolant with the same temperature as the difference in time of delivery will be insignificant. The pumps also maintain sufficient to Rise pressure, eliminating the cooling water in motion.

Types of circulating pumps

how to install the circulation pump in the heating

There are two types of such pumps. In the first case the rotor equipment is located in the zone of movement of the coolant that involves the use of latest and as a lubricant. This so-called wet rotor configuration characterized by simple design, Ease maintenance and quiet operation. But it is important to consider some features of installation of such units. How to install the heating system circulation pump This type?

Installation is only possible in a horizontal position relative to the earth's surface. Inclined and especially vertical layout can lead to hardware failures in the first weeks of operation. Also because of the modest performance of this model set mostly in small houses – the efficiency of the units rarely exceeds 50%. The second type of circulating transfer pumps represent models provided isolated from the coolant to the rotor. The advantages of this technique applies an efficiency of about 70% and high Reliability. However, in the process of operation will require a regular update of the lubricating oil.

Configuration of the placement of the unit

pump circulation systems

The layout of the pump is determined by the system exhaust the coolant. That is, the configuration of channels through which cold water is returned to Boiler. In Infloor system terminal connections of batteries and radiators can be connected to the lines which deliver the coolant. In this case, the reduced heating efficiency with respect to the points of heating, which will be supplied with a mixed environment. Such a circulation system assumes that the pump needs to be at the point of receipt of water for boiler equipment. But more productive in terms of Volume heat transfer two-pipe scheme. It allows you to fully share the contours of the areas of hot and cold water, Without reducing the effectiveness of of operation of the heaters. In such systems it may be required to install a second pump – at the outlet from the heating source.

Installing a circulation pump in the system

Before Assembly it is necessary to perform a flushing of the heating circuits,to duct out of sedimentary elements. The presence of foreign particles after repair operations, for example, can bring the equipment to malfunction. Just install the circulation pump in the heating system is By the mounting unit to a discharge or delivery tube. The frame is made complete with fittings, using plumbing tools. It is important to note that before and after the point of placing the pump must be located and shut-off valves. They will in the event of equipment failure to stop the delivery of water and perform repairs.

setting the circulating pump to the system

Next should the test phase. The contours must be filled with coolant and then pressure test. It must conform to the optimal level for the specific heating system and the parameters of the pumping unit. If necessary, you can make and Compressing, which will reveal the possible areas of leakage. But the work setting might hinder the Airing tubes. How to install the circulation pump in the heating system to initially from the pipeline was Deleted excess air? To do this immediately after mounting the unit, you must run the water and open all valves. This is the basic operation for the removal of air in the circuits, you want Repeat several times, at intervals of 15 min.

Feedback about the systems with pump circulation

The Owners of houses with similar communications noted the undoubted advantage of them in terms of effective support pressure coolant. Many point to the ergonomics of control systems for pumps, which enable precise regulation of the hot water. However the circulation system has some drawbacks. Chief among these is the requirement for regular maintenance. For example, models of pumps, Secured isolated rotor will always need effective lubrication.

Conclusion

installing a circulation pump in the heating system

Using water as the coolant to this day is the Cheap method of the organization of heating systems. Alternative electric radiators are expensive because of the cost of electricity and gas equipment deters many risk of accidents. But and circulating system, which delivers water to the radiators, is not the ideal solution. If the operation of such communication regularly perform their tasks which is a plus, the stage of the technical organization of the pipeline gives a lot of trouble. It should be added and the need to integrate the pump, and further measures for its maintenance.
