Below is the on-site installation process for high-flow, high-head multi-stage pumps. During installation, safety regulations must be strictly followed to ensure the safety of personnel and equipment. If there is anything unclear or uncertain, consult a professional or the manufacturer immediately.

I. Preliminary Preparations

1. Site Survey: Ensure that the work environment meets installation requirements, including power, water sources, and terrain.

2. Material Preparation: Prepare all necessary installation materials, such as pipes, valves, flanges, and seals.

3. Tool Preparation: Prepare the necessary installation tools, such as lifting equipment, welding equipment, and measuring tools.

II. Installation Process

1. Foundation Acceptance: Check if the pump foundation is level and firm to ensure pump stability.

2. Pump Positioning: Position the pump according to the design drawings to ensure the installation location meets design requirements.

3. Installation of Anchor Bolts: Secure the pump's anchor bolts to the foundation and tighten them.

4. Lifting the Pump Body: Use lifting equipment to lift the pump body to the designated location.

5. Connecting Inlet and Outlet Pipes: Connect the pump's inlet and outlet pipes according to the design requirements, ensuring the pipe direction is correct and the seal is good.

6. Motor Installation: Install the motor on the power end of the pump, ensuring a firm connection between the motor and the pump.

7. Wiring and Debugging: Connect the power lines, conduct a motor test run, and ensure the pump's operating direction is consistent with the design direction.

8. Lubricant Addition: Add the appropriate amount of lubricant to the pump and motor as required.

9. Pressure Gauge and Valve Installation: Install pressure gauges, valves, and other auxiliary equipment at the required locations.

III. Post-Installation Inspection

1. Check if all connections are tight and ensure there is no looseness.

2. Check if the direction of the pump and motor conforms to the design requirements.

3. Check if the lubricant is normal and if all lubrication points are working properly.

4. Check if the pressure gauge and valves are working normally.

IV. Test Run

1. Conduct a pump test run to check if the pump runs smoothly and if there is any abnormal noise or vibration.

2. Check if the flow rate, head, and other parameters meet the design requirements.

3. Check the sealing condition to ensure there are no leaks.

V. Maintenance and Management

1. Regularly maintain the pump, including changing the lubricant and checking fasteners.

2. Regularly check the operating condition of auxiliary equipment, such as pressure gauges and valves.

3. Establish operating records, recording the pump's operating time, operating conditions, etc., to provide a basis for future maintenance.
