KQM泵是专门为将泵直接安装在管道上而设计的。泵的自重及重心允许所有型号水泵直接安装在管路中,只要水泵的安装在所有工况下部不受应力。除此之外,用地基支持也可以。安装时,除水泵电机头部不允许朝下外,其它任何安装方位均可。
泵头(电机、连接座和叶轮)可直接从顶部拉出拆卸,而不影响管路。对于功率大于7.5kw的电机,建议安装和保养时使用相应吊装滑轮装置。本系列水泵都可安装底板,以便水泵必要时可以安装在地基上。
1、符合分担
对于功率大于1.5kw的水泵,“负荷等分法”为系统提供了最佳的解决方案。“负荷等分法”即:把最人负荷分配到两台小泵或一台双联泵上,来代替一台大泵。通常在整个供暖和供冷期,85%以上仅一台基泵工作就足够了。另一台泵,只是在供暖或供冷高峰投入工作,以满足最大负荷要求。
负荷等分法优点
一节能50%到70%
一总有一台备用泵
所谓的“符合等分法”就是一台泵作为基泵工作时,另一台泵作为备用泵,只是存供暖或供冷高峰期才投入工作。
2、 投资费用
根据“负荷等分法”原理所确定的双联泵可节约总投资近1/4。尤其是,如果用两台单泵代替双联泵,将使安装费用人大增加。
3、运行费用
双联泵大大节省了运行费用。在供暖和供冷季节,大部分时间(85)%是低负荷或部分负荷。根据“符合等分法”原理所确定的双联泵,使水泵在部分负荷时,更充分得到利用(在高效率下工作),因而大大节约了电能,减小了运行费用。
4、备用
当部分负荷或低负荷时,总有一台水泵作为备用泵(100%备用)。当满负荷时,如果一台水泵出现故障,另一台水泵作为“紧急泵”也可至少满足75%的需求。
5、注意事项
1)、管路水力损失与流速成正比。用户应根据实际使用工况.在设计、配置管路时综合考虑管路流速设计的合理性。尤其双泵同时运转时,流量增加近一倍,特提醒注意。
2)、气蚀余量是实测值,实际使用时至少应加0.5m的安全余量。

原文:
KQM pump is designed for the pump directly installed on the pipe and design. Pump weight and center of gravity to allow all types of pumps installed directly in the pipeline as long as the water pump installed in all operating conditions from the Ministry of stress. In addition, foundation support can also be used. Installation, in addition to pump motor does not allow the head down, the other can be any installation position.
Pump head (motor, connecting Oil pumps
blocks and impeller) can be pulled directly from the top of the demolition, without affecting pipeline. For the power is greater than 7.5kw motor, it is recommended to use the appropriate installation and maintenance of hoisting pulley device. This series of pumps can be installed floor to pump if necessary, can be installed on foundations.
1, in line with shared
For the pump power is greater than 1.5kw, "load equal portions Law" for the system to provide the best solution. "Load Dividers Law", namely: the most people load assigned to the two small pump or a double-pump on the pump instead of a National Taiwan University. Usually the entire heating and cooling period of more than 85% is only a story platform pump work is sufficient. Another pump, only in the peak heating or cooling to work, to meet peak load requirements.
Load Dividers Act Benefits
An energy-saving 50% to 70%
One always a spare pump
The so-called "consistent with attainment Law" is a pump as the base pumps work, another pump as afire pumps
standby pump, only a deposit before the peak heating or cooling to work.
2, investment costs
According to "load decile Law" principle established by double-pump can save a total investment of nearly 1 / 4. In particular, if a single pump instead of using two double-pumps, the NPC will increase the cost of installation.
3, operating costs
Double-pump significant savings in running costs. In the heating and cooling seasons, most of the time (85)% is a low-load or part load. According to "consistent with attainment Law" principle established by double-pump, so pump at part load, the more fully utilized (in the high-efficiency work), thus greatly saves energy, reduces operating costs.
4, standby
When the part-load or low load, there is always a water pump as a standby pump (100% standby). When the full load, if a pump fails, another pump as the "Emergency Pump" can alsoSplit case pumps
meet at least 75% of the demand.
5 Notes
1), pipeline hydraulic losses and flow rate is proportional to. Users should be based on actual working conditions. In the design, configuration, pipeline flow pipe comprehensive consideration when designing is reasonable. In particular, pairs of pumps running at the same time, the flow rate nearly doubled reminded to pay attention.
2), cavitation margin is the measured value, the actual use of at least 0.5m of the safety margin should be added.
