旋翼式热量表基表设计中应注意的问题

The problems in design of rotor heat meter's base table

我国政府政策规定新建居住建筑使用热量表作为热计量工具。目前我国自主研发的热量表多为机械式热量表,为获得最佳的热量表性能,在基表设计中应注意选择合适的基表形状、叶轮叶片数目、采用分流片、加装调节肋板等,以满足测量精度的要求。

In order to save energy and promote the heating system, our government demands new residential buildings to use heat meters as a metering tool. At present the heat meters that our country has independently developed ave mostly mechanical meters. In order to obtain the best peoformauee, we should pay attention to select the appropriate shape and the number of impeller blades in the base table design, and we also need to use the shunt plate, the adjustment ribbed plate and so on, to satisfy the request of measuring accuracy.
