Core technology-backwash device

Backwash device

Equipment used to clean the filtration system. Its main function is to flush the filter element or filter material through reverse water flow to remove accumulated dirt and impurities to ensure the efficient operation of the filtration system.

Backwash function

Clean the filter material, extend the life of the equipment, prevent the filter from being contaminated or blocked through regular backwashing, reduce the equipment failure rate, improve processing efficiency, realize automated operation, reduce manual intervention, and improve the overall automation level of the equipment.

Reliability and efficiency

Highly automated, reducing manual intervention, lowering labor costs, and efficient cleaning. Backwashing can effectively remove sediments and dirt in the filter material, maintain a stable filtration effect, and overcome the shortcomings of traditional manual cleaning.
Regular backwashing prevents filter clogging and maintains water quality, thereby improving the reliability and stability of the sewage lifting system and extending the service life of the equipment.

Fluid Dynamics - Herringbone Summary Tube

Herringbone summary tube

A tee or wye fitting joins three pipes to combine or divide the flow of water or air.

Better fluid dynamics

Uniform flow distribution:The outlet of the herringbone summary pipe uses a reasonable flow channel design to reduce the sharp turns of the water flow, make the flow distribution more uniform, avoid the problem of uneven flow in traditional pipelines, and reduce resistance.
Improve drainage efficiency and reduce clogging:In the subway sewage lifting system, the sources of sewage are complex. The collection method of the herringbone summary pipe can more effectively merge multiple flows, improve drainage efficiency, reduce the possibility of water accumulation, and reduce the risk of blockage. Low maintenance cost, strong adaptability and good engineering applicability.
Environmental protection and energy saving:By reducing unnecessary turns and joints and optimizing the water flow path, the herringbone summary pipe can reduce water flow energy loss and improve drainage efficiency, which not only benefits the system itself, but also indirectly reduces overall energy consumption and meets environmental protection, energy saving and emission reduction requirements.

Compared with traditional pipelines

The structural design is better and more in line with the principles of fluid dynamics. It is suitable for various spatial layouts, simplifies construction, and greatly reduces failure rates and labor costs.

Precise control-dual level control system

Micro air pressure + float double liquid level

Micro-pressure sensing combined with float level is a liquid level detection method that integrates micro-pressure sensing technology and float level monitoring technology. The system monitors liquid level changes in real time through the buoyancy of the float, and uses a micro-pressure sensor to accurately measure the pressure change corresponding to the position of the float, thereby achieving accurate liquid level measurement.

Dual control advantage

High precision and reliability:Micro-air pressure sensing: By detecting changes in micro-air pressure on the liquid surface, it can provide very accurate liquid level readings, is sensitive to liquid level changes, and is suitable for high-precision liquid level monitoring systems. Float level: The float is a mechanical liquid level control device that floats as the liquid level changes. It directly controls the switch to realize liquid level control. It has strong adaptability to liquid level fluctuations, simple structure, stable and reliable.
Double guarantee to reduce failure rate:The use of dual control can avoid possible failures caused by a single control method. For example, the micro-barometric pressure sensor may be affected by the external environment (such as temperature, pressure, etc.), and the float level can be used as a backup to ensure normal operation even if the sensor has errors.
Efficient alarm and security protection:When the liquid level is abnormal, the system can combine two methods to send out an alarm signal to promptly prompt the operator to intervene to avoid safety hazards caused by too low or too high liquid levels. The dual control can also be set up as "redundant control". For example, when the micro-pressure sensor detects an abnormality, the float system can automatically take over to ensure uninterrupted liquid level control.
