# 8-Inch 180-370 m³/h TDMD280-43 Diesel Engine Multistage Pump: การวิเคราะห์เชิงลึก
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, การตรวจสอบอุณหภูมิแบริ่ง, การป้องกันโพรงอากาศ, และการป้องกันหลายอย่างสําหรับเครื่องยนต์. 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: \[ \frac{P_1}{P_2} = \left(\frac{n_1}{n_2}\right)^3 \]
\[ \text{กําลังไฟ} = \frac{\text{ไหล} \times \text{หัว} \ครั้ง 9.81}{3600 \times \text{ประสิทธิภาพ}} \ครั้ง 1.25 \]
### Speed Parameters
– **Lower Limit Speed**: 1200 รอบต่อนาที
– **Upper Limit Speed**: 1750 รอบต่อนาที
## บทสรุป
