设计制作了两种五孔测球测架,采用数字压差仪量测测球测孔的压力和压差,较一般方法提高工效15倍左右,并给出水泵流场测试应用实例。
Two kinds of five-hole measuring sphere measuring rack are designed and manufactured, and the pressure and pressure difference of the measuring hole are measured by digital pressure difference meter. Compared with the common method, the work efficiency is increased by 15 times. The application example of the pump flow field testing is given.
