Texas Auto Traders constant pressure water system installations hydrostatic pressure head as the initial design of the expansion tank, as in the fixed line terminal expansion tank pressure head within the guarantee system uses water pressure is not vaporized. First start up the pump to the system and the initial running water chamber pressure tank filled with water, the system is filled with excess water squeezed inside the capsule. Because of the incompressibility of the water, with the increasing amount of water, the volume of the water chamber has been the expansion of the compression chamber, the pressure tank also continuously increasing. When the pressure reaches the design pressure, through the pressure controller makes up the water pump is turned off. When the thermal expansion of the water within the system so that the system pressure rises above the design pressure, the excess water to drain through the safety valve makeup tank recycling, when the water in the system due to leakage or temperature drop volume is reduced, system pressure is lowered, the capsule The water is constantly pressed into the pressure drop pipe network complement system, when the system pressure is the lowest pressure allowed to design when making up the pump by pressure controller to restart the pipeline network and water pressure tank, again and again. Texas Auto Traders constant pressure water system has opened up a new era of central air pressure maintenance system, the series of constant pressure device for any heating and cooling systems. The system can ensure the air in the system to solve the problem, even if the highest point and any possible corner of the gas system does not exist. Expensive, decentralized mechanical air separators and complex artificial exhaust system no longer needed. This series is widely used in the life, production and fire systems residential, hotels, hospitals and other civil and industrial facilities, the majority of users trust and praise. A Texas Auto Traders constant pressure water system works: in a closed loop system, in order to ensure the stability of the system pressure regulator to set the expansion facilities. When the system pressure decreases, water pressure chamber pressure tank connected to it also will decrease the volume of the expansion chamber, the pressure also decreases, the limit set under the control of the system to automatically turn on the water pump, water to the system until it reaches the set set pressure limit, the pump stops running. When the water heating system, temperature, volume expansion, the extrusion chamber, the pressure system pressure increases, the limited value, the system will be through the water safety relief valve to the expansion (or softened water tank), system pressure will drop to the set value, stop relief
