Why is the oil in my BUSCH COBRA Water Pump black?
If the oil in your BUSCH Water Pump is black, it could be that the oil change intervals are too long. Drain the old oil and refill with new oil. The machine may also be running too hot.
What to do if oil in my BUSCH COBRA Water Pump is black?
If the oil in your BUSCH Water Pump is black, it could be caused by: * Oil change intervals being too long. Drain the old oil and fill with new oil. * The machine running too hot. Refer to the troubleshooting steps for "The machine runs too hot".
What to do if my BUSCH Water Pump does not start?
If your BUSCH Water Pump isn't starting, several factors could be at play. It might be that the motor isn't getting the right voltage, so check the power supply. Alternatively, the rotors might be stuck; try turning them manually using the rotor access plug. If that doesn't work, the machine may need repair by BUSCH. Solid matter could also be inside; remove it or have the machine repaired, and consider installing an inlet filter. A temperature sensor might have triggered a shutdown, so let the machine cool down. Corrosion from remaining condensate could also be the culprit, requiring repair and a check of your processes. Finally, the motor itself could be defective and require replacement.
Why is my BUSCH COBRA Water Pump running too hot?
If your BUSCH Water Pump is running too hot, it could be due to several reasons. Ensure that you are meeting the cooling water requirements. The ambient temperature or the temperature of the process gases at the inlet may be too high; check the permitted temperatures in the technical data. Another potential cause is a defective cooling water pump, which would require repair. Finally, check the oil level and top up if it is low.
What to do if my BUSCH Water Pump doesn't reach the usual pressure?
If your BUSCH Water Pump isn't reaching its usual suction pressure, the suction or discharge lines might be too long or too small in diameter. Try using larger diameter or shorter lines. Process deposits on the pumping components could also be the problem; in this case, flush the machine. Also, ensure the machine is running in the correct direction by checking the wiring diagram. Lastly, worn or damaged internal parts can cause this issue, requiring a machine repair by BUSCH.
How to fix a noisy BUSCH COBRA Water Pump?
If your BUSCH Water Pump is running very noisily, it might be due to the wrong oil quantity or an unsuitable oil type. Use one of the recommended oils in the correct quantity. Alternatively, there may be defective gears, bearings, or coupling element, which would require a machine repair by BUSCH.
Why my BUSCH Water Pump does not start?
Several factors can prevent your BUSCH Water Pump from starting. It could be due to the motor not receiving the correct voltage, so check the power supply. Alternatively, the rotors might be jammed; in this case, contact Busch for repair. Solid foreign matter inside the machine can also be a cause; remove any foreign matter and consider installing an inlet filter. Lastly, a defective motor will also prevent the pump from starting, requiring a replacement.
What to do if my BUSCH COBRA Water Pump runs too hot?
If your BUSCH Water Pump is running too hot, several factors could be the cause. First, ensure that the cooling liquid requirements are met. The ambient temperature could be too high, so observe the permitted ambient temperature. High process gas temperature at the inlet can also cause overheating, so check the permitted gas inlet temperature. Finally, check the oil level and top up if it is too low.
What to do if BUSCH COBRA Water Pump suction pressure is low?
If your BUSCH Water Pump isn't reaching its usual suction pressure, several factors could be responsible. Excessively long or narrow suction or discharge lines can be the cause, so try using larger diameter or shorter lines. Process deposits on the pumping components can also reduce pressure; flush the machine to resolve this. If you have an inlet screen or filter, a partial clog could be the issue; clean the screen or replace the filter cartridge. Also, ensure the machine is running in the correct direction. Finally, internal wear or damage can cause low pressure; in this case, contact Busch for repair.
Why does my BUSCH COBRA run too hot?
If your BUSCH Water Pump is running too hot, it could be due to: * Insufficient cooling. Ensure you comply with the cooling water requirements. * The ambient temperature being too high. Observe the permitted ambient temperature. * The temperature of the process gases at the inlet being too high. Observe the permitted gas inlet temperature. * A defective cooling water pump. Repair the machine. * The oil level being too low. Top up the oil.
