The utility model content
The purpose of this utility model namely produces thus, proposes a kind of ultrapure water machine of high-low pressure automatic protection functions, makes machine when high pressure or pressure do not reach nominal parameter, the machine auto stop.
For achieving the above object, the utility model is achieved through the following technical solutions; A kind of ultrapure water machine of high-low pressure automatic protection functions, comprise through 2 minutes PE water pipes introduce source water the essence filter, with essence leach that the mouth of a river is connected be valve, be the valve water outlet be connected be pump, be to pump the filtering system that the mouth of a river is connected and the water intake valve that is connected with filtering system; Also has automatic gauge control.
It is characterized in that being: increased low pressure sensing protector and high pressure sensing protector;
Integrated control mainboard: mainly be comprised of Chip Microcomputer A LT89852, the control signal of micro-chip output is connected to after the A/D conversion and describedly is valve and is pump;
Low pressure sensing protector: before described low pressure sensing protector is installed on the essence filter of machine; whether monitoring source water pressure reaches the trigger pressure 〉=0.1MPa of machine, and less than 0.1MPa, system does not work and is in the lack of water alarm condition such as the source water pressure; as satisfy trigger pressure, system's water processed of starting working then.
High pressure sensing protector: described high pressure sensing protector is installed between UF system and the water intake valve, and ultrapure water machine is in water process processed, and when internal system pressure reached 0.25MPa, system stopped water processed, is in holding state; (get the water of machine) when diminishing such as machine intimate pressure, system begins again automatically to move water processed.
Above-mentioned filtering system is comprised of the RO system, UP system, UV system, the UF system that connect in turn through 2 minutes PE water pipes.
The beneficial effects of the utility model are:
1, intake pressure is crossed when hanging down, but self-protection, and not so machine down is that valve will shorten greatly with the work-ing life that is pump;
When 2, machine intimate pressure reached, the machine auto stop was in stand-by state, did not need the technician to keep an eye on;
3, in sum, the utility model reduces the manpower and financial resources of unit to a great extent.

Wherein: the smart filter of 1-, 2-are that valve, 3-are pump, 4-RO system, 5-UP system, 6-UV system, 7-UF system, 8-water intake valve, 9-low pressure sensing protector, 10-high pressure sensing protector, the integrated control mainboard of 11-.
Embodiment
As shown in Figure 1:
A kind of ultrapure water machine of high-low pressure automatic protection functions, comprise through 2 minutes PE water pipes introduce source water essence filter 1, with smart filter that 1 water outlet is connected be valve 2, be valve 2 water outlets be connected be pump 3, be the filtering system that is connected of pump 3 water outlets and the water intake valve 8 that is connected with filtering system; Also has automatic gauge control.
Integrated control mainboard 11: mainly be comprised of Chip Microcomputer A LT89852, the control signal of micro-chip output is connected to after the A/D conversion and describedly is valve 2 and is pump 3;
Low pressure sensing protector 9: before described low pressure sensing protector 9 is installed on the essence filter 1 of machine; whether monitoring source water pressure reaches the trigger pressure 〉=0.1MPa of machine; such as the source water pressure less than 0.1MPa; system does not work and is in the lack of water alarm condition; as satisfy trigger pressure, system's water processed of starting working then.
High pressure sensing protector 10: described high pressure sensing protector 10 is installed between UF system 7 and the water intake valve 8, and ultrapure water machine is in water process processed, and when internal system pressure reached 0.25MPa, system stopped water processed, is in holding state; (get the water of machine) when diminishing such as machine intimate pressure, system begins again automatically to move water processed.
Above-mentioned filtering system is comprised of the RO system 4, UP system 5, UV system 6, the UF system 7 that connect in turn through 2 minutes PE water pipes.
Embodiment one:
Shown in Figure 1, the installation site of the pipeline flow process of ultrapure water machine inside and high-low pressure protection, connect with 2 minutes PE water pipes after the machine water inlet, at first through low-voltage variation 9 devices, monitoring source water pressure have do not reach the start pressure (〉=0.1MPa), reach start pressure such as pressure, transmit through the A/D converting unit and to cause integrated control mainboard 11 (shown in Figure 2), integrated control mainboard transmits to cause through the A/D converting unit again and is valve 2 and is pump 3, allows its duty water, otherwise, the water processed that then quits work reaches more than the 0.1MPa so low-voltage variation 9 systems play pressure exactly, and machine is start just, be lower than 0.1MPa and just quit work, low-voltage variation it be one and be in normally open; Low-voltage variation 9 is connected to smart filter 1 by 2 minutes PE water pipes later again; manage through 2 minutes PE again after the filtration and be valve 2 and be pump 3; be to connect the RO system 4 that causes by 2 minutes PE pipes again after pump 3 pressurizations; UP system 5; UV system 6; UF system 7; after filtering layer by layer; connect again and cause high voltage protective 10 devices; the monitoring machinery internal pressure; because pressure can slowly not become large when machine was fetched water in the process of water processed; when pressure reaches 0.25MPa; cause integrated control mainboard 11 (shown in Figure 2) through the transmission of A/D converting unit; integrated control mainboard 11 transmits to cause through the A/D converting unit again and is valve 2 and is pump 3, allows its water processed that quits work, such as pressure drop; system's Auto Power On water processed then; so high voltage protective 10 device just plays pressure system-down when reaching 0.25MPa, system's Auto Power On when being lower than 0.25MPa, high voltage protective 10 it be one and be in normally off; in the rearmost end of system a water intake valve 8 has been installed; also be to connect with 2 minutes PE water pipes, this valve is opened when water intaking, closes when not getting.
