What is the typical set pressure for the safety valve on the outlet pipeline of a metering pump?
The setting pressure of the safety valve on the outlet pipe of the metering pump needs to be determined based on specific circumstances. The factors generally taken into consideration include the design pressure of the piping system, the outlet pressure of the metering pump, and the flow rate. Typically, the set pressure is adjusted to a level slightly higher than the outlet pressure, to ensure that the safety valve opens in a timely manner when the pipeline system experiences overpressure, thereby releasing the excess pressure. At the same time, the set pressure should also meet the requirements of relevant design and safety specifications. Generally, the setting pressure of the safety valve on the outlet pipe of a metering pump is typically 1.1 to 1.5 times the outlet pressure. .
It should be set based on the pump manual, as well as the process pressure requirements at the pump outlet. For reference.
Take the smallest of the three values, and include some appropriate margin. 1. Maximum pressure that the pump body can withstand 2. Design pressure of pipes and fittings 3. Maximum design pressure of the downstream system
