Hotel living water supply equipment maintenance

Customer: shenzhen lo wu a large hotel

The life of the equipment: constant pressure water control equipment

Fault: yituo 2 pump frequency conversion control

Analysis: the customer called and said manual can work but the pressure is too high, frequency conversion constant pressure is not normal. According to the hotel with a constant pressure water supply analysis, frequency conversion water supply equipment life Set by the pressure tank, water pump, electric control cabinet, pressure controller, safety valve, pressure gauge, check valve, gate valve and pipe to form a perfect automatic frequency conversion water supply equipment. When the pump starts, by filling in the tank and the inlet valve to the tank at the same time fill gas hydrate, with the increasing of water level, the gas tank volume constant enrichment; Pressure increasing, when the stress reaches the club on the highest pressure, closed by a pressure sensing control pump. In the pump stop running time, because of the squeezed air has the expansion force, squeeze the water tank has a certain pressure and sent to the users. As the water outflow, tank water volume is reduced, the volume of air increases, both the tank pressure to reduce gradually, when the tank pressure to clubs set minimum pressure, started the pump operated by pressure sensor, this back and forth constantly stop starting to make the tube to reach the ideal effect of water supply. After the initial tests for the inverter fault, the inverter removed the detection module in bad, replacement driver module and frequency converter after repair, returned to normal after the debug parameter with the equipment.
