Device Overview YT-XG set the pressure device opened up a new era of central air-conditioning system pressure is maintained constant pressure device of the series for any heating and cooling systems. The system can be guaranteed to solve the problem of air in the system without the presence of gas, even the most points and any possible corner. Expensive, the distributed mechanical air separator and complicated artificial exhaust no longer need. The products are widely used in residential buildings, hotels, hospitals and other civil construction and industrial facilities of life, production and fire-fighting system, the majority of users trust and praise. The working principle of system the mathematics integrated control, pressure sensing device, gravity control devices, signal transfer system pressure and tank water level mathematics precise control of each unit action. Constant pressure pump and pressure relief valve to control pressure to keep the scope of the changes between ± 0.2bar. From atmospheric pressure inflows or outflows expansion of water through two separate expansion pipeline. Exhaust pressure circulating water into the atmospheric pressure in the exhaust process tank under reduced pressure, the gas-water separator, the precipitated gases discharged into the atmosphere through the exhaust valve. The reasons for the loss of water from the exhaust gas and the system piping drip water can be the control unit and the real-time monitoring, once below the set value, then automatically the amount of water in the water separator tank is determined by the water level sensor. Drainage system water temperature increases lead to ultra-high pressure into the basic tank, pressure to Baoding tank does not automatically discharged when the the basic tank water exceeds a predetermined value, the excess amount of water. The equipment features 1, compact structure, small footprint: The unit uses a split assembly, water pump and tank separately to minimize the footprint. Precise control: The system uses highly integrated control cabinet, able to accurately display the tank level and system pressure changes. 3, good air tightness: inside the tank is made of food grade natural rubber, the unique auto exhaust can quickly drain the gas in the system, the less gas-water contact, to ensure that no contamination. 4, easy to operate: The unit uses a Chinese user interface, simple and clear, the main users according to the actual situation, adjust the parameters to achieve the desired effect. Use 1, to maintain the level of installation. 2, the factory prior to pressure test the gas chamber inflatable, users do not need to be pressure tested, site installation shall not disassemble the tank, to prevent the tank body gas wounding or affect the tightness of the device. 3, the engine room should be well ventilated conditions at room temperature of not less than 2 ° C (winter), outdoor installation should consider freezing measures. Debugging debugging and found the tank to be inflated, should be strictly in accordance with the following procedures. 1) pressure tank debugger, the principle of nitrogen in the water after the first charge. Filled with water, urban water supply system filled with water. Filled with water when the exhaust valve opens when the water chamber after the air exhausted to stop water-filled, close the exhaust valve began to inflate. 2) Inflatable first electrical contacts on the next pointer to the needs of the most
