KQM pumps are specifically designed to install pumps directly on the pipe. The weight and center of gravity of the pump allows all types of pumps to be installed directly in the pipeline as long as the pump is installed under all conditions without stress. In addition, it is also possible to use foundation support. Installation, in addition to the pump motor head does not allow downward, any other installation orientation can be.
The pump head (motor, connection seat and impeller) can be pulled out directly from the top without affecting the piping. For motors with a power of more than 7.5kw, it is advisable to use the appropriate lifting pulley for installation and maintenance. This series of pumps can be installed on the floor, so that pumps can be installed on the foundation if necessary.
In line with the sharing
For pumps with a wattage greater than 1.5kw, the "load sharing method" provides the best solution for the system. "Equal load method" means allocating the most load to two small pumps or one double pump instead of one large pump. It is usually enough to work with more than 85% of a base pump throughout the entire heating and cooling period. Another pump, just put in the heating or cooling peak to work in order to meet the maximum load requirements.
The advantages of a load sharing a 50% energy saving to 70%
There is always a spare pump
The so-called "in line with the equalization method" is that when one pump is working as a base pump, the other pump is used as a backup pump, and only put into work when it is stored for heating or cooling.
Investment costs
According to the "load sharing method" principle to determine the double pump can save a total investment of nearly 1 / In particular, if two single pumps are used instead of tandem pumps, installation costs will increase dramatically.
Operating costs
Double pump saves running costs. During the heating and cooling season, most of the time (85%) is low or partial load. According to the principle of "in line with the law" determined by the double pump, the pump at part load, more fully utilized (at high efficiency work), thus saving energy and reduce operating costs.
spare
When part load or low load, there is always a pump as a backup pump (100% standby). At full load, if one pump fails, the other pump can also meet at least 75% as an "emergency pump".
Precautions
1, pipeline hydraulic loss and flow rate is proportional to. Users should be based on the actual use of conditions. When designing and configuring the pipeline, the rationality of the design of the pipeline flow velocity should be considered. In particular, double pump at the same time operation, the flow increased nearly doubled, special reminder note.
2, cavitation margin is the measured value, the actual use of at least 0.5m should be added safety margin.
