Seeking the whole process of the head test pressure, text description, detailed point,
Test pressure 1. Test pressure single test pressure and system test pressure, single test pressure: after the completion of the trunk pipe or hidden parts of the pipeline installation is completed according to the design and specification requirements for water pressure test. System test pressure: heating system installed according to the design and specification requirements for system water pressure test. 2. Heating, air conditioning system test procedures: a first check the entire system of all control valves are open, the system should be separated from the outer pipe network, open the gas tank release valve. B will be the water main pipe, test pressure pump and other temporary pressure test pipe connected to the main water supply pipe, and irrigation to the system, to be filled with water system and cutting ingot Cui melon Chaozhao sleep bile duct system After the discharge of the air, the release of the valve out of the water so far), close the release valve; c operation test pump to boost, boost the process should pay attention to check management, fittings and accessories are leaked, such as seepage Leakage should stop the pressure to suppress, and after the buck to repair, change pad, tighten and so on. D system without leakage, the pressure and boost to the test pressure, stop the pump check, and observe the pressure gauge, requiring 10 minutes pressure drop of not more than 0.02Mpa, that is qualified.
1. Test pressure single test pressure and system test pressure, single test pressure: pipe laying or hidden parts of the pipeline after the completion of installation and design requirements according to the requirements of water pressure test. System test pressure: heating system installed according to the design and specification requirements for system water pressure test. 2. Heating, air conditioning system test procedures: a first check the entire system of all control valves are open, the system should be separated from the outer pipe network, open the gas tank release valve. B will be the water supply pipe, test pressure pump and other temporary pressure test pipe connected to the main water supply pipe, and irrigation to the system until the system filled with water and the pipeline system after the air drained (put the wind gate workers The valve out of the water so far), close the release valve; c operation test pump to boost, boost the process should pay attention to check the management, fittings and accessories are leaked, such as leakage should stop the pressure, and after the buck Repair, change pad, tighten and so on. D system without leakage, the pressure and boost to the test pressure, stop the pump check, and observe the pressure gauge, requiring 10 minutes pressure drop of not more than 0.02Mpa, that is qualified.
