Process Flow
1. Preparation before Start - up
Check whether all components of the equipment are firmly connected, whether the lubricating oil and grease are sufficient, whether the electrical system is normal, and whether the cooling system and nitrogen system can work properly. Conduct a leak - tightness check on the pipelines and valves to ensure there are no leaks.
2. Starting the Equipment
First, start the cooling system to ensure the normal circulation of the cooling medium, and then start the nitrogen system (if required). Then start the motor and drive the screw pump to operate through the reducer.
3. Operation Monitoring
Real - time monitor parameters such as the pumping rate, vacuum degree, motor current, temperature, cooling water flow rate and pressure, nitrogen system pressure and flow rate to ensure the normal operation of the equipment. According to the process requirements, control the gas flow rate and pressure by adjusting the valves.
4. Stopping the Equipment
First, stop the motor, then close the cooling system and nitrogen system (if they are turned on), and close the relevant valves. Clean and maintain the equipment, check the wear of vulnerable parts, and replace them in a timely manner.
Equipment Installation
1. Foundation Preparation
According to the weight and size of the screw pump, make a suitable concrete foundation to ensure that the foundation is flat and firm and can withstand the vibration and weight during the operation of the equipment.
2. Equipment Positioning
Use lifting equipment to hoist the screw pump onto the foundation, adjust the position of the equipment to make its levelness meet the requirements. Connect the inlet and exhaust pipelines well, and pay attention to the slope and tightness of the pipelines.
3. Electrical Connection
Connect the power lines and control lines of the motor according to the electrical schematic diagram to ensure that the electrical connection is correct and safe. Install a grounding device to prevent electric leakage accidents.
4. Connection of Cooling and Nitrogen Systems
Connect the cooling water pipelines to ensure the correct flow direction of the cooling water and good sealing of the interfaces; connect the nitrogen system pipelines to ensure that the pressure and flow rate meet the equipment requirements.
5. Commissioning and Operation
After completing the equipment installation and connection, conduct commissioning and operation. Check the operating status of the equipment, adjust the relevant parameters to make it reach the best working state.
Answers to Common Questions about Titanium - Series Screw Pumps
1. How to Select the Appropriate Model of the Titanium - Series Screw Pumps According to Actual Needs?
Select according to parameters such as the required pumping rate, ultimate full pressure, maximum exhaust pressure, etc., combined with the corrosiveness, temperature, pressure, and other conditions of the actual working conditions. At the same time, consider factors such as motor power and installation space. For example, if the required pumping rate in chemical production is 540m³/h, the LGB150D model can be selected.
2. What are the Reasons and Solutions for Excessive Noise during the Operation of the Titanium - Series Screw Pumps?
Possible reasons include loose installation, insufficient lubrication, and component wear. Solutions include re - tightening the installation components, adding or replacing lubricating grease and oil, and checking and replacing worn components.
3. How to Maintain the Patented Internal Cooling Structure of the Titanium - Series Screw Pumps?
Regularly check whether the cooling water pipelines are blocked or leaking, and ensure the normal flow rate and pressure of the cooling medium. Regularly clean the cooling system to prevent impurities and scale from affecting the cooling effect.
4. When the Series of Screw Pumps is Applied in the Chemical Industry, How to Ensure the Corrosion - Resistance Performance?
Select the appropriate TA2/TA10 titanium material, avoid over - temperature and over - pressure operation, regularly inspect and maintain the equipment, and discover and handle corrosion problems in a timely manner.
5. What Should be Noted during the Installation of the Complete Skid - Mounted Design of the Titanium - Series Screw Pumps?
Ensure that the foundation is firm and the equipment levelness meets the requirements; pay attention to sealing when connecting pipelines to prevent leakage; the electrical connection should be correct and safe; check whether the connections of the cooling and nitrogen systems are normal.
6. How Often Should the Lubricating Oil and Grease of the Titanium - Series Screw Pumps be Replaced?
According to the operating time and working environment of the equipment, generally, the lubricating oil is replaced every 1000 - 1500 hours of operation, and the lubricating grease is replenished or replaced every 500 - 800 hours of operation.
7. What to Do if the Cooling Water Temperature is too High during the Operation of the Series of Screw Pumps?
Check whether the cooling system is blocked and clean the cooling water pipelines; check whether the cooling water pump is working properly and repair or replace it if necessary; increase the cooling water volume or reduce the inlet water temperature.
8. What is the Function of the Nitrogen System of the Titanium - Series Screw Pumps?
In some special processes, the nitrogen system is used to provide a protective gas to prevent the medium from contacting the air and causing oxidation, explosion, and other dangers. It can also be used to purge the inside of the equipment to keep the equipment clean.
9. How to Judge Whether the Pumping Rate of the Titanium - Series Screw Pumps is Normal?
Monitor the pumping rate through a flow meter installed on the pipeline and compare it with the rated pumping rate of the equipment. If the actual pumping rate is significantly lower than the rated value, check whether the pipeline is leaking, whether the pump body is worn, and whether the valve is opened normally.
10. Does the Price of the Titanium - Series Screw Pumps Have an Advantage Compared with Their Performance?
Although the price is relatively high, considering its excellent corrosion - resistance performance, stable operation performance, multi - scenario applicability, and the convenience brought by the patented internal cooling structure and complete skid - mounted design, it has a high cost - performance ratio in terms of long - term use costs and production benefits.
