Abstract
The invention provides a security filter differential pressure alarm system, which is composed of a security filter, pre-filtration pressure detection module, a post-filtration pressure detection module, a differential pressure detection module, a relay output module and an audible and visual alarm. The alarm system is characterized in that: the security filter and the differential pressure detection module are respectively connected to the pre-filtration pressure detection module and the post-filtration pressure detection module, and the relay output module is connected to the differential pressure detection module and the audible and visual alarm. According to the invention, when the differential pressure between the front and the back of the security filter is too large, the alarm system can timely remind a user of replacement of a filter core, and guarantees the final treatment effect and treatment efficiency of direct drinking water equipment.
Description
Technical field
The present invention relates to a kind of pressure reduction warning system, specifically a kind of cartridge filter pressure reduction warning system.
Background technology
At present, in society, most of direct drinking all adopted cartridge filter to filter before carrying out counter-infiltration or ultrafiltration technology, when before and after cartridge filter, pressure reduction is excessive, if can not reminding user to replace filter core in time, the treatment effect that Potable water equipment is final can be affected, and reduce the efficiency of direct drinking process.
Summary of the invention
In view of the deficiency that above-mentioned prior art exists, cartridge filter pressure reduction warning system provided by the invention, when before and after cartridge filter, pressure reduction is excessive, can timely reminding user to replace filter core, the treatment effect that guarantee Potable water equipment is final and treatment effeciency.
The technical solution adopted for the present invention to solve the technical problems is: cartridge filter pressure reduction warning system is made up of pressure detecting module, pressure differential detection module, relay output module and audible-visual annunciator after pressure detecting module, filter before cartridge filter, filter, cartridge filter and pressure differential detection module are respectively with pressure detecting module before filter with filter afterwards pressure detecting module and be connected, and relay output module is connected with audible-visual annunciator with pressure differential detection module.
The invention has the beneficial effects as follows, when before and after cartridge filter, pressure reduction is excessive, can timely reminding user to replace filter core, the treatment effect that guarantee Potable water equipment is final and treatment effeciency.
Accompanying drawing explanation
Accompanying drawing 1 is principle assumption diagram of the present invention.
In figure, 1, cartridge filter, 2, pressure detecting module before filter, 3, pressure detecting module after filter, 4, pressure differential detection module, 5, relay output module, 6, audible-visual annunciator.
Detailed description of the invention
With regard to accompanying drawing 1, following detailed description is done to cartridge filter pressure reduction warning system of the present invention below.
As shown in Figure 1, cartridge filter pressure reduction warning system of the present invention is made up of pressure detecting module (3), pressure differential detection module (4), relay output module (5) and audible-visual annunciator (6) after pressure detecting module (2), filter before cartridge filter (1), filter, cartridge filter (1) and pressure differential detection module (4) are respectively with pressure detecting module (2) before filter with filter afterwards pressure detecting module (3) and be connected, and relay output module (5) is connected with audible-visual annunciator (6) with pressure differential detection module (4).
Before filter, pressure detecting module and the rear pressure detecting module of filter detect the pressure before and after cartridge filter respectively, and the numerical value detected is passed to pressure differential detection module, before and after cartridge filter, pressure reduction exceedes setting value, the adhesive of pressure differential detection module control relay output module, after relay output module adhesive, audible-visual annunciator is reported to the police, and reminding user needs to change filter core of security filter.
Claims (1)
1. cartridge filter pressure reduction warning system is made up of pressure detecting module, pressure differential detection module, relay output module and audible-visual annunciator after pressure detecting module, filter before cartridge filter, filter, it is characterized in that: cartridge filter and pressure differential detection module are respectively with pressure detecting module before filter with filter afterwards pressure detecting module and be connected, and relay output module is connected with audible-visual annunciator with pressure differential detection module.
