Description
Technical field
The utility model relates to energy-conservation HVAC equipment technical field, is specifically related to a kind of constant pressure water compensation apparatus.
Background technology
In current HVAC and refrigeration industry, central air-conditioning and heating system must adopt constant pressure supply water and the device that the water quality of above system processes do not vaporized with guarantee system, do not turn, not superpressure, do not corrode and the limit pressure water feeding equipment of non-scaling.
At present, the limit pressure water feeding equipment of central air-conditioning and heating system, general employing is every pattern constant pressure water compensation apparatus and frequency conversion constant pressure water compensation apparatus, every pattern constant pressure water compensation apparatus, the water yield that absorption system expands due to water heating, therefore, equipment volume is huge, floor space is large, equipment is not easy to transport and install, equipment manufacturing cost is high, in addition, and supplementing water pressure instability fluctuated.Existing frequency conversion constant pressure water compensation apparatus, when system constant pressure point reaches the force value of setting, the frequency conversion small pump run still does not stop, all the time be in a kind of low-frequency running status, therefore, waste electric energy, add the wearing and tearing of small pump and shorten service life, simultaneously, user need separately join storage tank and water treatment facilities, to solve the substandard problem of moisturizing water quality, thus adds occupation of land space.
Summary of the invention
Technical problem to be solved in the utility model is the deficiency for above-mentioned existence, provides a kind of structure simple, cheap, there is stable supplementing water pressure, economize energy, improves the service life of small pump, solves the constant pressure water compensation apparatus of the quality problem of moisturizing simultaneously.
The utility model solves the technical scheme that its technical problem adopts:
Constant pressure water compensation apparatus, is characterized in that: include level pressure expansion drum, base, small pump, switch board, connecting line, safety attachment, instrumentation; Wherein base is fixed on square concrete basis, base is provided with level pressure expansion drum, and the top of level pressure expansion drum is provided with automatic exhaust steam valve, and bottom connects a butterfly valve by main line, this butterfly valve is communicated with two small pumps respectively by two stop valves, and two small pumps connect two check-valves respectively; Two described stop valves connect a ftercompction pipe, and ftercompction pipe is provided with Pressure gauge and safety valve; Base is also equipped with control cabinet support, support fills a switch board.
In such scheme, be provided with air bag in described level pressure expansion drum, the aerating device of air bag is by line connection control cabinet.
In such scheme, described small pump is connected with water supply tank by water inlet, and ftercompction pipe is provided with delivery port, and delivery port is connected with system constant pressure point.
Principle of the present utility model is: by distance-transmission pressure gauge, the pressure signal in pipeline is transferred to digital display Instrument for Pressure, by the moisturizing of programme-control automatic constant pressure, superpressure sluicing, low pressure and overpressure alarm; By liquid level sensor, the liquid level signal of softened water tank is transferred to digital display level meter, is reported to the police and lack of water self-locking by programme-control softened water tank lack of water.Adopt isolating transformer to power to digital displaying meter, to suppress interference, and play the effect of open-phase protection.Digital automatic setting pressure water make-up arrangement can accurate display system pressure, and digital display is program control, stable performance, compact conformation, simple installation
Technical advantage of the present utility model is:
The utility model structure is simple, cheap, has stable supplementing water pressure, economize energy, improves the service life of small pump, solves the quality problem of moisturizing simultaneously.
