Regarding Installation
Select an Appropriate Location: The syrup pumping pump should be installed in a dry, well-ventilated place that is convenient for operation and maintenance, with enough space reserved around it. Avoid installing it in an environment with high temperature, humidity, or corrosive gases to prevent affecting the pump's performance and service life.
Connect Pipes Correctly: Ensure that the inlet and outlet pipes are firmly connected and there is no leakage. The diameter of the pipes should match the inlet and outlet diameters of the pump to reduce resistance. At the same time, pay attention to the support of the pipes to avoid the weight of the pipes being applied to the pump body, which may affect the normal operation of the pump. For pipes transporting syrup, it is recommended to use stainless steel or food-grade plastic materials to prevent contamination of the syrup.
Install a Filter: Install a suitable filter at the inlet of the pump to prevent impurities, particles, etc. in the syrup from entering the pump body, causing wear or blockage and affecting the normal operation of the pump. The precision of the filter should be selected according to the quality of the syrup and the requirements of the pump.
Inspection Before Startup
Check the Appearance of the Pump: Check whether there is any damage or deformation to the pump body, whether the connecting parts are loose, and whether there are any signs of leakage at the seals.
Check the Lubrication and Cooling System: For pumps that require lubrication and cooling, check the oil level and quality of the lubricating oil to ensure that the oil level is within the normal range and the oil quality is good, without phenomena such as deterioration or emulsification. At the same time, check whether the cooling system is normal and whether the cooling liquid is sufficient.
Check by Hand Cranking: Manually turn the coupling or pulley of the pump to check whether the pump rotates flexibly and whether there is any sticking, friction, or abnormal noise.
Check the Electrical System: Check whether the wiring of the motor is correct and firm, whether the grounding is good, and measure the insulation resistance of the motor, which should meet the requirements. At the same time, check whether the power supply voltage is within the rated voltage range of the pump, and the voltage fluctuation should not exceed the specified value.
Pump Priming and Air Exhaustion: Before starting the pump, the pump casing and the inlet pipe need to be filled with syrup to expel the air. For self-priming pumps, you can open the inlet valve to let the syrup flow into the pump naturally, and at the same time, open the exhaust valve on the pump casing until the discharged gas is completely replaced by the syrup, and then close the exhaust valve. For non-self-priming pumps, the syrup needs to be filled into the pump through a priming device.
Operation During Running
Start the Pump: After completing the inspection before startup, close the power switch to start the pump. When starting, pay attention to observing the starting current and running sound of the pump. If there is any abnormality, stop the machine immediately for inspection.
Adjust the Flow Rate and Pressure: According to actual needs, control the flow rate and pressure of the syrup by adjusting the opening degree of the outlet valve. During the adjustment process, pay attention to observing the operating parameters of the pump, such as current, pressure, etc., to avoid the pump running under overload or idling conditions. For some pumps with variable frequency speed regulation function, the flow rate can be adjusted by adjusting the frequency of the frequency converter to change the rotation speed of the pump.
Monitor the Operating Status: During the running process of the pump, pay close attention to various operating parameters of the pump, such as flow rate, pressure, temperature, current, vibration, etc., to ensure that these parameters are within the normal range. At the same time, pay attention to observing whether there is any leakage at the seals of the pump. If there is leakage, stop the machine in time for handling. In addition, regularly check the quality of the syrup to prevent the pump from contaminating the syrup.
Prevent Dry Running: During the running process, ensure the continuous and stable supply of syrup to avoid the pump running dry. If there is a situation of insufficient syrup supply, stop the machine in time, find out the cause, and restart the pump after solving the problem.
Shutdown Operation
Close the Outlet Valve: Before shutting down, gradually close the outlet valve of the pump to reduce the load of the pump, and then cut off the power supply to stop the operation of the pump.
Empty the Syrup in the Pump: If the pump needs to be shut down for a long time or undergo maintenance, empty the syrup in the pump to prevent the syrup from solidifying or deteriorating in the pump. When emptying, you can open the drain valve on the pump casing to let the syrup flow out naturally, and then clean the pump with clean water or a suitable cleaning solution.
Keep a Shutdown Record: Record information such as the shutdown time of the pump, the running situation, and whether there are any abnormalities, so as to provide a reference for the next use or maintenance.
Maintenance and Upkeep
Regular Inspection: Regularly conduct a comprehensive inspection of the pump, including the wear conditions of components such as the pump body, impeller, shaft seal, and bearings. If there is any wear or damage, replace them in a timely manner. At the same time, check whether the connecting parts of the pipes are loose and whether the seals are aging or ineffective. If there are any problems, repair or replace them in a timely manner.
Cleaning and Maintenance: Keep the pump clean and regularly remove the dust, oil stains, and syrup stains on the surface of the pump body. For the filter, clean or replace the filter element regularly to ensure its filtering effect. In addition, pay attention to keeping the surrounding environment of the pump clean and avoid the accumulation of sundries.
Replace Vulnerable Parts: According to the usage situation of the pump and the manufacturer's suggestions, regularly replace vulnerable parts such as seals, impellers, and bearings. The wear of these vulnerable parts will affect the performance and reliability of the pump, and timely replacement can extend the service life of the pump.
Maintenance for Long-term Shutdown: If the pump needs to be shut down for a long time, empty and clean the syrup in the pump, and then apply an anti-rust oil to the surface of the pump to prevent rust. At the same time, seal the inlet and outlet pipes of the pump with blind plates to prevent sundries from entering the pump.
The specific usage methods and maintenance requirements may vary for different types and models of syrup pumping pumps. Therefore, before using the pump, be sure to carefully read the pump's instruction manual and operate and maintain it according to the manufacturer's requirements.
