Data Center Circulating Water Pump Self-Cleaning Filter
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing circulating water pumps in data center computer rooms face issues with filter plate blockages and impurity accumulation, leading to decreased pressure and cold water circulation speed, which can affect the normal operation of the unit. Additionally, the existing filter plates require manual cleaning, which is cumbersome and disrupts the operation of the pumps.
Innovation Solution
A circulating water pump designed for data center computer rooms, featuring two cleaning pipe components that operate alternately, a flow meter for detecting cold water flow rate, and a PLC controller to manage the electric butterfly valve and blowdown solenoid valve. This setup allows for automatic cleaning of blocked filter plates without stopping the pump, using backflush and rotary scrubbing mechanisms to effectively remove impurities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If filter plates are installed at inlets of circulating water pumps to remove impurities, then filtering efficiency is improved, but the filter plates become blocked over time requiring shutdown and manual cleaning
Solution Approach 1:
The filter plate cleaning mechanism enables the system to clean itself automatically during operation. The cleaning component with scrubbing brushes and high-pressure water jets is driven by the pump's own motor without requiring external intervention or system shutdown, allowing the filter plates to be cleaned autonomously while maintaining continuous water circulation.
Solution Approach 2:
The cleaning mechanism is designed to operate concurrently with the pump's normal operation. The cleaning component can be activated during pump operation to clean filter plates without interrupting the water circulation process, ensuring continuous useful action of both filtering and pumping functions.
2Device complexity
If simple filter plates are used in circulating water pumps, then device complexity is reduced, but pressure loss increases and circulation speed decreases when filter plates are blocked
Solution Approach 1:
The automated cleaning mechanism with scrubbing brushes and water jets continuously removes impurities from filter plate surfaces, preventing blockage accumulation. This self-cleaning function maintains high water circulation speed and low pressure loss without requiring complex manual intervention systems.
Solution Approach 2:
The cleaning mechanism performs preliminary cleaning actions on the filter plates before complete blockage occurs. By continuously removing impurities during operation, it prevents the formation of severe blockages that would cause significant pressure loss and circulation speed reduction.
3Device complexity
If manual cleaning of filter plates is required, then device complexity is reduced, but maintenance time and operational disruption increase
Solution Approach 1:
The system incorporates an automated cleaning component that operates during pump operation to clean filter plates without requiring external manual intervention. The cleaning mechanism is driven by the pump's own motor and uses the pump's water flow to perform cleaning, eliminating the need for separate maintenance operations and reducing maintenance downtime to near zero.
Solution Approach 2:
The cleaning function is merged with the pump's operational cycle. The cleaning component is integrated into the pump housing and operates using the pump's own motor and water flow, combining the pumping and cleaning functions into a single integrated system that performs both tasks without requiring separate maintenance interruptions.
