Description
Technical field
The present invention relates to a kind of water supply installation, particularly the multistage constant pressure water supply equipment of a kind of haemodialysis water making device.
Background technology
Haemodialysis water making device is the water treatment facilities specially needed for haemodialysis, and patient passes through the pellicle of haemodialyser or filter for blood dialysis, contacts weekly the water more than 300L possibly.And the people that healthy, the water taken in weekly rarely exceeds 12 liters, increases nearly 30 times with the Exposure of water, therefore, should control and monitor water quality, to avoid known or that estimation is harmful material excessive.That prepares dislysate usually all will through certain process with water, and water quality reaches the requirement of regulation.The equipment performance of water treatment system how, depends on the water quality of former water and the function of whole system, sees that can it prepare and continuous production goes out qualified process water.
Under existing technical condition, adopt two main pumps to provide enough hydraulic pressure as compression system with this, but the variation in water pressure scope that the method provides is comparatively large, is difficult to ensure stable water pressure, filter core is impacted comparatively large, easily damage filter core.
Summary of the invention
The object of the invention is to the shortcoming overcoming prior art; there is provided a kind of and export water pressure invariableness, filter core can be protected to increase the multistage constant pressure water supply equipment of haemodialysis water making device in its application life; this device is by keeping constant with parallel connection of pumps return valve with the hydraulic pressure controlling to export; avoiding causing cartridge surface to be subject to hydraulic pressure because pump output variation in water pressure is comparatively large impacts fragile, thus improves the application life of filter core.
The object of the invention is to be achieved through the following technical solutions: the multistage constant pressure water supply equipment of a kind of haemodialysis water making device, it comprises water pump A, storage tank, water pump B, strainer, water pump C, valve A, first level filtering device, water pump D, valve B and two-stage filter, according to water (flow) direction, described water pump A, storage tank, water pump B, strainer, water pump C, first level filtering device, water pump D and two-stage filter pass through cross current successively, water pump C is other is parallel with valve A, valve A is by the cross current at water pipe and water pump C two ends, water pump D is other is parallel with valve B, valve B is by the cross current at water pipe and water pump D two ends.
Described strainer is a tertiary filter be made up of sand filtering device, dechlorination device and deionizer.
Described valve A is return valve.
Described valve B is return valve.
Pipeline between the pipeline at described strainer and valve A place is provided with a circulation high pressure sense switch.
The present invention has the following advantages: the present invention makes output water pressure invariableness by return valve pressure regulation; make pressure stability in first level filtering device filter core, two-stage filter filter core; can avoid being subject to variate hydraulic pressure to impact; improve application life, thus it have structure simple, export water pressure invariableness and filter core can be protected to increase the advantage in its application life.

In figure, 1-water pump A, 2-storage tank, 3-water pump B, 4-strainer, 5-circulation high pressure sense switch, 6-water pump C, 7-valve A, 8-first level filtering device, 9-water pump D, 10-valve B, 11-two-stage filter.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention will be further described, and protection scope of the present invention is not limited to the following stated:
Fig. 1 is the multistage constant pressure water supply equipment structural representation of a kind of haemodialysis water making device, and the multistage constant pressure water supply equipment of a kind of haemodialysis water making device, is characterized in that: it comprises water pump A1, storage tank 2, water pump B3, strainer 4, water pump C6, valve A7, first level filtering device 8, water pump D9, valve B10 and two-stage filter 11, in the present embodiment, described strainer 4 be one by sand filtering device, the tertiary filter of dechlorination device and deionizer composition, the pipeline between the pipeline at strainer 4 and valve A7 place is provided with a circulation high pressure sense switch 5, according to water (flow) direction, described water pump A1, storage tank 2, water pump B3, strainer 4, water pump C6, first level filtering device 8, water pump D9 and two-stage filter 11 pass through cross current successively, water pump C6 is other is parallel with valve A7, valve A7 is by the cross current at water pipe and water pump C6 two ends, water pump D9 is other is parallel with valve B10, valve B10 is by the cross current at water pipe and water pump D9 two ends, in the present embodiment, described valve A7 is return valve, and described valve B10 is return valve.
The course of work of the present invention is as follows: after switching on power; starting water pump A1 can to water storage in storage tank 2; water in storage tank 2 is drawn out of by unlatching water pump B3 and is flowed to strainer 4 and makes it tentatively to be filtered, and elimination large granular impurity, to protect the filter core of subsequent filter device.Starting water pump C6, that the water tentatively filtered through strainer 4 is pumped to first level filtering device 8 filter core is peripheral, utilizes high pressure principle of reverse osmosis to be compressed to filter core by preliminary filtered fluid, and some impurity depart from due to the obstruction of filter core and water, are filtered in cartridge surface.When water pump C6 output hydraulic pressure is greater than the force value of setting, before partially liq is back to water pump C6 by valve A7, again circulated by water pump C6, make the hydraulic pressure in first level filtering device 8 keep constant, avoid first level filtering device 8 filter core because be subject to fluctuate larger compression shock and damaging; It is peripheral that the water filtered through first level filtering device 8 is pumped to two-stage filter 11 filter core by water pump D9; high pressure principle of reverse osmosis is utilized to filter further; when water pump D9 output hydraulic pressure is greater than the force value of setting; before partially liq is back to water pump D9 by valve B10; again circulated by water pump D9; the hydraulic pressure in two-stage filter 10 is made to keep constant; avoid two-stage filter 11 filter core because be subject to fluctuate larger compression shock and damaging, protect filter core with this, extend its application life and realize the function of constant pressure water supply.
