- Abstract:
- Aiming at the current situation that the cold and hot water cyclic testing can not be carried out for the water supply pipeline system due to lack of testing equipment, an automatic cold and hot water cyclic testing equipment for the pipeline system is developed. The device adopts a double pump pressurization structure, two pneumatic three-way connections are used to switch the circuit, and a proportional relief valve is installed on the circuit to control the system pressure through throttling. A quick clamping structure of pipe fittings is designed to facilitate the rapid loading and unloading of pipeline systems of different specifications. The working principle, mechanical structure, performance parameters and working procedure of the equipment were introduced in detail. Through threeyear’s testing, the equipment proved to be easy to operate, stable in operation, reasonable in parameter design, which can meet the requirements of product quality assurance and standard requirements.
