The drainage hydraulic trailer series (model ZGT-500100/2000) is an efficient emergency drainage equipment independently developed by Huangshan Zhongguangtai Special Equipment Co., Ltd. It includes three specifications: 500m3/h, 1000m3/h, and 2000m3/h, and is specifically designed for flood control and emergency rescue, municipal drainage, and engineering emergency situations. The series adopts a trailer-mounted structure, integrating hydraulic power, drainage, intelligent control, and auxiliary lighting systems. It features flexible mobility, efficient drainage, and convenient operation, and can meet the rapid response needs for various large-scale water accumulation emergencies.

"Series common features

1. Overall design and maneuverability

All adopt a steel structure frame trailer chassis, equipped with torsion bridge shock absorption, driving mechanical inertia braking and parking braking systems. The driving speed is 30 km/h, the turning speed is 10 km/h, and it can adapt to grade III highways and low-speed off-road conditions. The chassis contains 4 adjustable support legs (with mechanical swing arms), which can be flexibly disassembled to ensure operational stability. The entire vehicle adopts an integrated rainproof and silent body (≥1.5mm cold-rolled steel plate, electrostatic spraying for rust prevention), with internal filling of sound insulation cotton. The noise at 7 meters is ≤80 dB, and it has the ability to work outdoors in all weather conditions."

"2. Power and Control System

The hydraulic power station is equipped with a Wuxi diesel engine, meeting the emission standards of Stage III. The fuel tank capacity is 100-120L, and it can support full-power operation for more than 8 hours. It is equipped with a digital intelligent control system, featuring a Chinese visual interface, supporting remote start and stop, and having multiple protection functions such as overcurrent, leakage, undervoltage, and overheating. It also comes with an emergency stop button to ensure operational safety.

3. Core Components of the Drainage System

The single hydraulic submersible pump has a rated flow rate of 500m3/h (with a lift height of 10m). The hydraulic components (such as the impeller and pump shaft) are made of 304 stainless steel and are integrated. It can pass through 25mm solid particles and is suitable for complex water quality. The standard configuration includes a DN200 polyester long-fiber polyurethane water hose (working pressure 0.9MPa, burst pressure 3.2MPa) and a polyurethane float ring. The hose connector is a stainless steel quick interface, facilitating quick deployment.

4. Auxiliary Functions and Safety

The exterior of the enclosure is equipped with warning lights and reflective strips. Optional features include a lifting light (2×100W LED, lifting height 1.2m, 360° rotation) and a collision avoidance radar module (measurement range ≥ 4m, accuracy 0.05m). A maintenance tool kit is provided with the vehicle for convenient on-site maintenance."

"Application scenarios and advantages

This series of products are widely used in various fields such as flood emergency drainage (urban flooding, low-lying areas, tunnel water accumulation), construction engineering drainage (basements, underground garages), agricultural drought resistance and irrigation, and fire-fighting remote water supply. Its core advantages lie in:

Grade-specific adaptation: Different discharge capacity models can meet the differentiated needs ranging from small water accumulation to large-scale floods;

Efficient deployment: The modular design supports rapid loading and unloading, and the hydraulic system responds quickly, with water being discharged within 3-5 seconds;

Durable and reliable: Stainless steel components and anti-corrosion treatment ensure the equipment's long-term operation in humid and highly contaminated environments;

Intelligent and convenient: Remote control and automatic protection functions reduce the manual workload and improve the emergency response efficiency.

This series has passed ISO9001 quality system certification and complies with multiple national standards such as GB7258 and GB1589. It is an efficient and reliable drainage solution in the field of emergency rescue."
