Hey there! I'm a supplier of self-priming oil pumps, and I know that starting one up after a long-term shutdown can be a bit of a headache. But don't worry, I'm here to walk you through the process step by step.
Why is Starting After Shutdown Tricky?
When a self-priming oil pump sits idle for a long time, a bunch of things can go wrong. The oil inside might thicken, seals can dry out, and there could even be some corrosion. All these issues can stop the pump from working properly when you try to fire it up again.
Pre-Start Checks
Before you even think about hitting the start button, there are a few things you need to do.
Visual Inspection
First off, give the pump a good once-over. Look for any obvious signs of damage like cracks in the casing, loose fittings, or frayed wires. Check the oil level in the reservoir. If it's low, you'll need to top it up. Also, make sure there are no leaks around the seals or connections.
Check the Power Source
If you're using an electric pump, ensure that the power supply is stable and the voltage is correct. For diesel-powered pumps, check the fuel level and the condition of the fuel lines. You don't want to run into any power issues right when you're trying to start the pump.
Lubrication
Long periods of inactivity can cause the moving parts to dry out. Apply some lubricant to the pump's bearings, shafts, and other moving components. This will help reduce friction and make it easier for the pump to start.
Priming the Pump
Priming is a crucial step in getting a self-priming oil pump up and running.
Manual Priming
Some pumps come with a manual priming mechanism. If yours does, follow the manufacturer's instructions to prime the pump. Usually, this involves filling the pump casing with oil and then using a hand pump or lever to create suction. This helps to remove any air from the system and get the oil flowing.
Automatic Priming
For pumps with automatic priming systems, the process is a bit simpler. Just make sure the pump is properly connected to the power source and the oil supply. The automatic priming system will do the rest, but it might take a few minutes for the pump to build up enough pressure to start pumping oil.
Starting the Pump
Once you've completed the pre-start checks and primed the pump, it's time to start it up.
Slow Start
If possible, start the pump at a low speed. This allows the pump to gradually warm up and get the oil flowing smoothly. Avoid starting the pump at full speed right away, as this can put unnecessary stress on the components.
Monitor the Pump
As the pump starts, keep an eye on it. Listen for any unusual noises like grinding, rattling, or squealing. These could be signs of a problem. Also, check the pressure gauge to make sure the pump is building up pressure correctly. If the pressure is too low or too high, there might be an issue with the pump or the system.
Troubleshooting
Even if you've followed all the steps correctly, you might still run into some problems.
No Oil Flow
If the pump is running but there's no oil flow, check the suction line for blockages. There could be debris or a kink in the line preventing the oil from reaching the pump. Also, make sure the valves are open and the oil filter is clean.
Overheating
If the pump starts to overheat, it could be due to a lack of lubrication, a blocked cooling system, or an electrical problem. Stop the pump immediately and let it cool down. Check the lubrication levels and the cooling fins or radiator. If the problem persists, you might need to call in a professional.
Different Types of Self-Priming Oil Pumps
There are several types of self-priming oil pumps available in the market, each with its own characteristics and starting procedures.
Electric Plunger Oil Pump
The Electric Plunger Oil Pump is a popular choice for many applications. It uses a plunger to create suction and pump the oil. When starting this type of pump after a long shutdown, make sure to check the electrical connections and the condition of the plunger.
Submersible Electric Oil Pump
The Submersible Electric Oil Pump is designed to be submerged in the oil. Before starting it, ensure that the pump is properly installed and the electrical cable is in good condition. Also, check the oil level in the tank to make sure the pump is fully submerged.
Self-priming Centrifugal Oil Pump
The Self-priming Centrifugal Oil Pump uses centrifugal force to pump the oil. When starting this pump after a long shutdown, pay special attention to the impeller. Make sure it's not damaged or blocked.
