It should be remembered that the parameters of centrifugal and axial pumps, even at a constant speed of rotation of the impeller are variable and depend on the filing. Graphs of the basic parameters of the pump from the feed pump are called characteristics. Centrifugal and axial flow pumps automatically respond to changes in feeding, changing the appropriate pressure.

Characteristics of pumps are constructed according to the results of field tests. Specifications are given for a certain frequency of rotation of the impeller. On the chart is often cited characteristics for reduced (peeled) diameter impeller. Point features corresponding to the maximum value of efficiency is called the optimum point of the regime. Its corresponding flow and pressure are called optimal pump parameters, and since 1977 part of the designation of the bronze pump model # 007.
Point corresponding to the actual mode of the pump – the working point does not always coincide with the optimal, but should, if possible, be close to her. Based on the allowable decrease in efficiency on characteristics often produce a working part, within which both must be working points of the pump. Characteristics of pumps provided by the manufacturers as a rule, for pure water at 20 ° C under normal atmospheric pressure at the level of global sea level.

What is the circulation pump

Circulator – a specially mounted pump, which instantly produces an internal air in difficult circumstances.

Use a circulating pump

Circulating pump – an important element of modern heating systems. Its application allows you to make better use of energy expended on heating the building. This is because, firstly, there is no need for a strong heating of the coolant required for circuits with natural circulation. Today, for example, are widely used system, where the temperature in the supply pipeline is maintained at 55oS. Secondly, there is an additional opportunity to adjust the flow of heat, depending on the need for it. In addition, the pump reduces the cost of the scheme as a whole, since it provides an opportunity to use pipe smaller than with the natural circulation diameter.

These circulators appeared some time ago, in the early 1950′s. In countries with decentralized heat they were very popular.

How does the circulator

The rotor of the circulating pump with the impeller immersed in the pumped medium. The fluid lubricates the bearings of the shaft and simultaneously cools the engine. Tightness of the engine parts, which is under stress, provides a dividing glass, made of stainless steel. The rotor shaft is often made of ceramics bearings – ceramic or graphite. The body pumps for heating systems in most cases, cast iron. For hot water, as a rule, apply the model with bronze or brass case.

Pumps of this type is practically noiseless and can operate for years without maintenance. Their installation, repair and replacement do not require labor-intensive operations, such as centering.

Technology development circulators

One of the ways to improve pumps like Taco Pump or Grundfos Pump was the union of its parts in blocks to facilitate their replacement. Such a unit can be easily disassembled into five modules: a pump casing, impeller, shaft bearings and the rotor, forming a single block in the cartouche, the motor housing with the stator, the terminal box.

Taco recently introduced its new customers submersible pumps series Taco 007 and Taco 009, made in stainless steel for use in Taco 007 Taco 006. These pumps were designed specifically to provide high hydraulic performance. It used high quality materials, which guarantees corrosion resistance, moreover, do not have to complain and to the rapid wear of the parts while working in hostile environments. These characteristics of pumps designed to preserve the excellent hydraulic performance during a long period. When it comes to work in a very aggressive hydraulic medium, such conditions there is a separate model of the pump, which is entirely made of duplex steel.

The entire range includes pumps five main dimensions, the range of characteristics is very wide. Most small model of the pump unit Taco 007 is characterized by a nominal supply of 150 cu. m / h, is the same major (Z12420) shows a nominal flow of 420 cubic meters. m / h. The range of characteristics of reliable power supply line to 520 cu. m / h, the pressure can reach 545 meters.

Injection pump with the use of wax castings (disposable) and design are key to excellent performance, their efficiency exceeds 80%, almost every operating point of 120 cu. m / h – 460 cu. m / h. High quality materials used, correctly selected thickness, sturdy construction pumps provide several advantages, distinguishing this line from the mass of ordinary models of cast iron.

Using the pumps for a long time, experts note that the bulk of operating costs are maintenance costs and energy consumption. Therefore, pumps out new line will likely be a good alternative to the old, not too rugged pumps, which show a rather low efficiency and require significant expenditures to maintain them in good condition.

New pumps Taco 0010, Taco 0012 can be applied to quite a lot of work, for example, they can be used to monitor water levels, fire and irrigation systems, pumping water from the wells of great depth, drainage, water supply and pressure increase (both in industry and in household systems).

Controllers LUX widely used for various radiant heating systems and plumbing of residential and office premises and are the analytical component of these systems. They are programmed to different versions of control schemes to maintain thermal comfort and rational allocation of energy resources and allow you to adjust, in addition to the heating circuit hot water system, ie, the coolant flow to maintain the desired temperature of hot water. The contour of heating and hot water are controlled independently from each other, thus ensuring a comfortable temperature in both circuits

More schedule changes and the heating function of “impact areas” allow the performance characteristics of your premises, thus allowing pre-programmed to change the values for standard rooms at the values required specifically for your premises. A possibility to connect the temperature sensor inside the room can also correct any deviation from a comfortable temperature. Weekly program of work proposed by the controller, provide a comfortable and economical mode of operation for office buildings. And the use of overtime mode, and the use of a special schedule avoids the need to reconfigure in the case of a single change work schedules.

The possibility of limiting the temperature coolant supply and coolant temperature, the return of the system avoids the possible destruction of the system, as well as potential fines from the heating networks. A delay function on or turn-off delay can be deleted cooling tank circuit hot-water supply by limiting the supply of cold water at the start of feeding (Taco pump is switched on only after the timed delay) and prevents overheating after the hot water into the room through the removal of residual heat due to the delay before turning off the Taco pump.

Until recently, heating and air conditioning to compensate for temperature expansion of the coolant expansion tanks are widely used open-type with a number of drawbacks, chief among them – the coolant in constant contact with the atmosphere, its intense evaporation and the need for regular replenishment of the system, as well as the presence in it of dissolved air .

The presence of bubbles, in turn, negatively affects the quality of the system as a whole and for its longevity, causing corrosion of internal elements and decreasing the heat transfer, leading to the formation of air pockets and disturbance of fluid circulation. In addition, air bubbles cause cavitation, which entails the destruction of the system elements that are in the cavitation zone: Taco pumps, Taco Zone valves, PEX pipe, etc.

Performance of Taco pumps

To convert the obtained value of m ^ 3 / h (typically, this is the unit of measurement of performance of pumps used in technical documentation) necessary to divide it into the water density (p) at the design temperature, at 70 C it is 977.0 kg / m ^ 3.

In addition to the required filing, the Taco 007 pump with IFC must provide pressure (pressure), enough to overcome the resistance of the pipeline network. For the right choice to determine the losses in the longest line of the scheme, ie to the farthest sink.
The resistance network of pipelines leading to a loss of pressure the liquid along the length of the network. Characteristics of the flow of fluid in the system shows the total resistance to flow: the cause of the resistance of the pipeline network are the friction of water on the walls of the pipe, the friction of water droplets between a change of direction in the fixture. When changing the volume of the fluid, for example, by opening or closing the thermostatic valves, changing the speed of water and accordingly the resistance of the pipeline network.
When designing the new system possible accurate calculations taking into account the resistance of all elements of the longest line (PEX pipes, PEX fittings, fixtures and appliances), and is usually necessary information contained in the passports of the equipment. In cases with the existing district heating such calculations, usually impossible. In such situations, most often used rough estimates.
These empirical data suggest that the resistance of straight segments of the pipe (R) is the order of 100-150 Pa / m. This corresponds to the required pump head in 0,01-0,015 m by 1 m of the pipeline. The calculations must take into account the length and inlet and return line. Also on the experience, it was determined that the fittings and accessories, lost about 30% of losses in straight pipe. If the system is the expansion valve, added another 70%. At the three-way tap in the node management of the entire heating system or device that prevents the natural circulation, accounting for 20%.

Formula for calculating the approximate pressure

Formula for calculating the approximate pressure (in meters) is as follows:

H = R · l · ZF (3)
ZF – the safety factor.

If the unit is not equipped with either thermostatic valve or faucet, ZF = 1,3; to the circuit with thermostatic valve ZF = 1,3 · 1,7 = 2,2; when the system includes both the device ZF = 1,3 · 1,7 · 1,2 = 2,6.

Having defined the so-called operating point of the circulating pump (pressure and flow) remains to find in catalogs pump with similar characteristics. For performance (V, m ^ 3 / h) operating point must fall into the middle third of the diagram (Fig. 1). Do not install more powerful pump than is required for perfect heating buildings. If the calculated point falls in the interval between the lines of the characteristics of the two closest to the parameters of Grundfos pumps, Taco pump should choose smaller capacity.

In the heating system with a few independent radiant heating circuits circulators are selected according to the hydraulic calculation for each radiant heating circuit separately. Within each separate radiant heating circuit, the branch having the maximum pressure drop [Pa], is crucial when choosing the pump. Head of H generated by the Taco pump, should bear the full pressure drop in the circuit (taking into account the pressure drop in the feeding arteries, Taco control valves, etc., most pump, and the gravitational component of pressure drop of the plots, where it acts as resistance). Maximum pressure drop in the system and the total flow volume loop determine the pump operating point (pressure and flow respectively). The Taco pump is selected correctly, if the working point lies on the characteristics of the pump at its maximum rotation frequency of the maximum efficiency of the pump (the best filing), or close to that point.
