Diesel Engine Multistage Pump: An In-Depth Analysis

# 8-Inch 180-370 m³/h TDMD280-43 Diesel Engine Multistage Pump: An In-Depth Analysis

The coupling of the diesel engine water pump features an integrated flexible vibration-damping design, which enhances transmission efficiency and reduces alignment requirements. It also dampens axial forces on the pump, minimizing wear on the balance plate during low lift or low-speed operations. The instrument system is equipped with waterproofing, water loss protection, bearing temperature monitoring, cavitation protection, and multiple safeguards for the engine. Overall, the pump operates stably and reliably, requiring minimal complex operation.

## Product Features

1. **Stable Flow and Pressure**: The pump exhibits minimal flow fluctuations and stable pressure, ensuring smooth operation with low center and high-end bearings.

2. **Optional Water Ring 304 DC Vacuum Assist System**: This system features fewer lines, antifreeze lubrication, and prevents jamming, contributing to stable operation.

3. **Rapid Water Intake**: The water ring vacuum pump can draw water within 60 seconds, with low power consumption and automatic dual-mode detection for outlet pressure.

4. **Semi-Sheltered Top-Hanging Collision Barrier**: This design facilitates easy relocation, offers rain protection, and ensures good ventilation.

5. **Strong Cavitation Resistance**: Even when using extended suction pipes, the pump maintains a significant flow output, demonstrating its robust design.

## Diesel Engine and Pump Power Calculation Method

Flow Rate Relationship: \[ \frac{Q_1}{Q_2} = \frac{n_1}{n_2} \]
Head Relationship: \[ \frac{H_1}{H_2} = \left(\frac{n_1}{n_2}\right)^2 \]
Shaft Power Relationship: \[ \frac{P_1}{P_2} = \left(\frac{n_1}{n_2}\right)^3 \]

\[ \text{정격 전력} = \frac{\text{흐름} \times \text{머리} \times 9.81}{3600 \times \text{능률}} \times 1.25 \]

### Speed Parameters

– **Lower Limit Speed**: 1200 분당 회전수
– **Upper Limit Speed**: 1750 분당 회전수

## 결론

Its robust construction, efficient operation, and advanced protective features make it a reliable solution for handling challenging pumping tasks. With its ability to maintain stable performance under varying conditions, this pump stands out as a critical asset in enhancing operational efficiency and reliability in water transportation systems.
