集中供热系统采用补水泵调速定压方式的探讨

目前随着住宅建设的快速发展和供热区域的扩大，在进行热水采暖系统的设计时选择正确的定压方式对系统的正常运行非常重要。就目前普遍采用的补水泵定压进行了探讨，提出了采用这种定压方式在现有设备的基础上，不仅扩大了供热面积，充分发挥了其供热能力，而且节省了基建投资，提高了供热效果，但在实际运行中也产生了一些问题，并提出了解决办法，还列举了实例加以证明。

Discuss on the speed governing and pressurization pattern adopting make-up water pump in central heat supply system

With the development of residential construction and expansion of heat supply area the accurate choice of pressurization pattern in the design has important significance for the normal operation of system. This article discusses the pressurization of using make up water pump. Adopting this method based on current equipments not only expands the heat supplying area but save construction cost, so the heating effect is enhanced. At the same time some problems are produced in operation. Author proposes some solving methods and provides examples to verify them.
