Is it necessary to install a safety valve at the outlet of the vortex pump?
Thread Content
According to Clause 5.5.1 of the \"Code for Fire Protection Design of Petrochemical Enterprises (2018 Edition)\” (GB 50160-2008), safety valves shall be installed on the following equipment that may experience overpressure under abnormal conditions: 3. The outlets of each stage of reciprocating compressors, or the outlets of positive displacement pumps such as electric reciprocating pumps, gear pumps, and screw pumps (except those already equipped with safety valves). Question: As a special type of centrifugal pump, the vortex pump also requires its valve to be opened before it can start operating; in the event of incorrect operation (starting with the valve closed), this can lead to overpressure in the pump and motor overload. Should safety valves also be installed on the outlet pipeline of vortex pumps, just like those of positive displacement pumps?
First, it is necessary to determine whether the working medium and operating conditions of your vortex pump in the process meet the specified requirements. For example, could the physical properties of the medium lead to a risk of overpressure during use???? For reference.
If overpressure is a possibility, a safety valve is required
