The invention provides a high-low parameter system pressure test device which comprises a pressure test pump, a high pressure branch and a low pressure branch, wherein the high pressure branch mainly comprises a first pressure release valve, a first pressure meter and a first ball valve which are connected in series, the head end of the high pressure branch is connected with a high parameter system, the tail end of the high pressure branch is connected with a pressure test pump, the low pressure branch mainly comprises a second pressure release valve, a second pressure meter and a second ball valve which are connected in series, the head end of the low pressure branch is connected with a low parameter system, the tail end of the low pressure branch is connected with the pressure test pump, and the tail end of the high pressure branch is connected with the tail end of the low pressure branch through a third ball valve. The invention further provides a high-low parameter system pressure test method. According to the method, after the pressure of the high parameter system is tested, the pressure of the low parameter system is then tested; the pressures of the high pressure system and the low pressure system are tested synchronously, the test efficiency is high, and the energy consumption is low.
Description
technical field [0001] The invention relates to a high-low parameter system pressure test method, in particular to a high-low parameter system pressure test device and a high-low parameter system pressure test method. Background technique [0002] The pressure test is an important work after the installation of the waste heat boiler. After the installation of each waste heat boiler, the pressure test must be carried out. In addition, according to the regulations, the boiler needs to conduct a pressure test every 3-6 years to check whether there is any leakage in the body, welds, and flange connections of the boiler equipment after operation. [0003] Waste heat boilers are generally divided into two parts: high parameter system and low parameter system. Among them, the high-parameter system includes economizer, steam drum, evaporator, superheater, steam header and connected pipes; the low-parameter system includes preheater, deaeration water tank, deaeration evaporator and ...
