Selection Calculation of Throttle Orifices of the Recycling Pipe of Condensate Pumps in the Chemical Industry

The recycling pipe of condensate pumps in the chemical industry always vibrates strongly and arises strong noise in engineering commissioning.In this paper,reasons of the vibration and noise were analyzed.Through reasonable calculation of the throtting orifice,reasonable selection of throttling orifice of the recycling pipe can be realized.Calculation methods of multistage throttle were introduced.The system failure was solved to ensure the safety operation of the system.
