Business Areas
DPS TECHNOLOGY was founded to build smart, safe drainage pump station equipment. We develop core technology that keeps equipment operating safely through disasters such as heavy rain and prevents accidents before they happen.
Intelligent Trash Rack Cleaner
A rotary trash rack cleaner that detects debris overload, rake deformation and drive shaft deformation in real time and controls its operation automatically. As a Performance Sharing success product, it is supplied to drainage pump stations nationwide.
Main Products
Smart Belt Conveyor
Belt conveyors that receive the debris lifted by the trash rack cleaner and carry it to the collection bin. Development of the smart belt conveyor is complete, and certification is in preparation.
Main Products
Gates · Movable Weirs
We fabricate and install roller gates, wire-rope movable weirs (tilting gates), emergency flood gates and gate hoists for drainage pump stations and reservoirs.
Main Products
Cranes · Hoists
We supply and install overhead cranes and hoists for drainage pump stations, pumping stations and environmental infrastructure facilities.
Main Products
Water Treatment Equipment
We supply water treatment equipment — mixers, rapid mixers, dewatering machines, deodorizers and more — for water purification plants, sewage treatment plants and night soil treatment facilities.
Main Products
Maintenance · Overhaul
From trash rack cleaner link chain replacement and conveyor and gate repair to turbine generator repair at small hydropower plants — we keep equipment running long after installation.
Main Products
An intelligent trash rack cleaner that detects faults first
It detects debris overload and structural deformation in real time and adjusts its operation automatically. Instead of repairing after a breakdown, it prevents the breakdown.
- 01
Debris overload detection
The load sensing module continuously monitors the load on the rake and, when an overload occurs, lowers the speed to reduce it.
- 02
Drive shaft overload · deformation detection
The drive shaft deformation sensing module detects excessive force on the shaft and protects the reducer and chain.
- 03
Rake deformation detection
The rake deformation sensing module detects bending or twisting of the rake and raises an alert before it develops into a major failure.
| Mode | Speed · Criteria | Notes |
|---|---|---|
| Raised standby (energy saving) | 3.0 m/min | Power consumption 0.8 kW or less |
| Light-load operation | 6.5 m/min | When debris is light |
| Constant-speed operation | 5.0 ~ 6.0 m/min | 2 stages |
| Overload operation | 2.0 m/min | Low speed under heavy load |
| Overload-reduction operation | When 200% is detected | Automatic reduction |
Development Status
We continue to develop core technology for disaster prevention. Once a product's development is complete, it goes through certification and is then deployed to sites.
Status by product
A predictive-maintenance trash rack cleaner that detects debris overload and rake and drive shaft deformation. As a Performance Sharing success product, it is being supplied to drainage pump stations.
Development is complete and certification is in preparation. Once certified, it can be supplied through negotiated contracts.
We steadily develop technology that keeps drainage pump station equipment operating safely during disasters such as heavy rain and prevents accidents in advance.
