Frequency of water supply equipment in the construction of water supply _ _ frequency of water supply plant

Constant pressure water supply equipment technical parameters are those? Constant pressure water supply equipment technical parameters are as follows: control: frequency control installation: indoor temperature: not higher than 40 ℃ transport medium: water medium temperature: cold water type 0 ℃ -70 ℃ hot water type 0 ℃ -180 ℃ Pumps: Vertical / horizontal centrifugal pump combination Number of units: 2-6 sets of Power: Three-phase / 380V / 50HZ capsule landing expansion tank water equipment is absorbing foreign advanced technology and the development of innovative achievements have unique energy efficient technology. It consists capsule expansion pressure tank, pump, automatic control cabinet, pipeline until the components. Products rational structure, advanced technology, reliable quality, superior performance, low prices. Capsule landing expansion tank water equipment can replace the high expansion tank is widely used for hot water supply, hot water heating, residential central heating and air-conditioning systems in order to achieve automatic replenishment system and constant pressure. Capsule landing expansion tank water supply equipment is widely used for domestic residential, office buildings, hotels, hospitals, research facilities and other civil and industrial enterprises, and the production and the fire service, to replace the water tower or high water tank, not only to reduce the civil engineering and process design The complex coefficient, and water conservancy condition is stable, easy to maintain management. When a floor-expansion tank for thermal systems at constant pressure, hot water heating or central air conditioning system due to rising water temperatures cause water to volume expansion of the inner pipe pressure exceeds the design pressure increases, part of the water will be squeezed capsule into the tank; when the system temperature drops, the volume of water is reduced, then the pressure in the capsule into the pipe network complement the work and so forth, so that the water flow and pressure never disorders, to prevent the presence of a vacuum or dry phenomenon, eliminates water hammer in the pipe network and noise. Frequency of water supply equipment principle | pressure water supply equipment principle Introduction | Water Supply Equipment according to user requirements, first set the water pressure, and powered operation, pressure sensor monitors pressure in the pipe, and into an electrical signal to the programmable controller or computer controller, the analysis process, the signal transmitted to the inverter to control pump operation, when the water increases, the voltage and frequency of its output increases, the number of revolutions the pump increases, the amount of water increases, when the water is reduced, Pump revolutions reduction, reducing the amount of water, so that the pipe network pressure to maintain the set pressure value ,, in multiple pump operation, by machine soft start, frequency by the frequency change jobs to a pressure flow is satisfied to achieve a circulation pump control, When nighttime low flow operation, work can be maintained by variable-speed pump, frequency conversion to pump can stop packing.
