Daxing differential pressure automatic control filter

.
Product Introduction:
The differential pressure automatic control filter determines the working status of the filter based on the pressure difference between the inlet and outlet water, and truly realizes the functions of automatic detection, automatic cleaning, and automatic sewage discharge. Differential pressure automatic control filters are suitable for air conditioning systems, cooling water systems, industrial water systems, and domestic water systems.
.
Working principle:
The differential pressure automatic filter mainly includes: shell, filter cartridge
(
Filtering dirt
)
, cleaning mechanism
(
Including cleaning brush, brushing filter
)
, controller
(
Collect and compare pressure difference signals, and output control signals
)
, cleaning motor
(
Receives control signals and provides the power required by the cleaning mechanism
)
, electric valve
(
Accepts control signals and discharges dirt
)
. When working, water flows through the filter cartridge, and the dirt is intercepted by the filter cartridge. When more and more dirt accumulates, the circulation area of the filter cartridge becomes smaller and smaller, causing the pressure difference before and after the water flows through the filter cartridge to become larger and larger. This The pressure difference is measured by the pressure sensor at the inlet and outlet and fed back to the controller. When the pressure difference reaches the upper limit of the controller's allowable value (this value is set by the user), it indicates that too much dirt has accumulated in the filter cartridge, affecting the normal flow of water. At this time, the controller outputs a signal, turns on the cleaning motor, drives the cleaning mechanism to operate, brushes the filter screen, and at the same time opens the electric drain valve to discharge the dirt. After the dirt is discharged, the filter flow area returns to normal, and the pressure difference before and after the water flows through the filter cartridge decreases. When the pressure difference reaches the lower limit of the controller's allowable value (this value is set by the user), the controller outputs a corresponding signal and shuts down cleaning. motor, close the electric drain valve. So far, the differential pressure automatic control filter has achieved the water filtration effect and ensured the normal operation of the entire system.

Performance features:
()
Fully automatic operation: After setting the data once, it can automatically detect the inlet and outlet pressure difference, automatically clean the filter screen, and automatically discharge sewage, truly Achieve unattended operation.

()
Accurate and reliable: The core component of the differential pressure controller is an imported brand, which has the advantages of accurate measurement and reliable control, eliminating the phenomenon of equipment not working or shutting down due to measurement and control errors. .

()
Reasonable configuration: Use an electric butterfly valve as a drain valve to solve the problem of loose valve closing and unstable quality. It can also prevent the solenoid valve from opening too fast and causing excessive pressure on the system. Impact.

()
Advanced design: It absorbs Israel's advanced automatic filtration technology and adopts a unique dual structure of brushing and sucking, which can completely remove dirt.

()
Multiple self-protection: The controller is equipped with working time limit protection. When a fault occurs, the filter will be clogged with a large number of foreign matter that cannot be removed, resulting in excessive pressure loss and the filter will always be cleaned and sewage discharged. In the status, the continuous cleaning time is controlled within minutes and an alarm is issued.

()
Careful processing: strict quality assurance system, strict organization, careful processing, leading quality, and service life of more than
years. (Different interface methods such as straight-through, same side, and different sides can be manufactured according to user requirements. Filters with high-precision specifications can also be manufactured according to user requirements)
