The 25th National "Safety Production Month" in 2026. Everyone pays attention to safety and everyone will investigate and rectify potential risks in an emergency. -------------------------------------------------- "Pipeline Instrument Flowchart Basic Unit Model" (HG 28559-1993) 3.0.2.1 All pump outlets must have at least a local indicating pressure gauge located between the pump outlet and the first valve. "Design Specification for Pump Area of ​​Petrochemical Storage and Transportation System" (SH/T 3014-2025) 8.1.1 The pump outlet pipeline should be equipped with a pressure detection instrument, and the inlet pipeline of the heating medium pump should be equipped with a temperature detection instrument. The temperature and pressure signals should be introduced into the control system. "Code for Construction and Quality Acceptance of Automated Instrument Engineering" (GB 50093-2013) 3.0.2.1 All pump outlets must have at least a local indicating pressure gauge located between the pump outlet and the first valve. "Code for construction and acceptance of installation projects of fans, compressors and pumps" (GB 50275-2010) 4.1.5(2) The inlet and outlet pipes of the pump should have their own brackets, and the pump must not directly bear the mass of the pipes, etc. "Technical Specifications for Fire Water Supply and Fire Hydrant Systems" GB50974-20145.1.17 Pressure gauges should be installed on the suction pipes and outlet pipes of fire water pumps, and should comply with the following regulations: 1. The maximum range of the fire water pump outlet pipe pressure gauge should not be less than 2 times its design working pressure, and should not be less than 1.60MPa ； 2. The fire water pump suction pipe should be equipped with a vacuum gauge, pressure gauge or vacuum pressure gauge. The maximum range of the pressure gauge should be determined according to the specific conditions of the project, but should not be less than 0.70MPa. The maximum range of the vacuum gauge should be -0.10MPa. ； 3. The diameter of the pressure gauge should not be less than 100mm, and a pipe with a diameter of not less than 6mm should be used to connect the inlet and outlet pipes of the fire water pump, and a shut-off valve should be installed. 5.1.11 A group of fire water pumps should be equipped with flow and pressure testing devices in the fire water pump room, and should comply with the following regulations: 1. When the flow rate of a single fire water supply pump is not greater than 20L/s and the design working pressure is not greater than 0.50MPa, the pump set should reserve flow meter and pressure meter interfaces for measurement. Other pump sets should be equipped with pump set flow and pressure testing devices. ； 12.3.2 The installation of fire water pumps should meet the following requirements: 8. A silencer check valve, control valve and pressure gauge should be installed on the outlet pipe of the fire water pump. ； A pressure gauge and pressure switch should also be installed on the main water outlet pipe of the system ； A buffer device should be installed when installing the pressure gauge. A cock should be installed between the pressure gauge and the buffer device ； When there is no design requirement, the pressure gauge range should be 2 to 2.5 times the system working pressure. ； "Code for Selection and Design of Petrochemical Automation Instruments" SH∕T 3005-20166.2.2 Provisions: The selection of pressure gauges used for special media and special occasions should comply with the following regulations: e) When installed in a vibrating place or vibrating part, a vibration-resistant pressure gauge should be selected. Vibration-resistant methods can include filling the dial with filling fluid and/or adding dampers;
