What are the reasons for the decrease in oil pressure of Weifang generator? ‌

2024-10-24 14:36:07Font scaling:




The main reasons for the decrease in oil pressure of Weifang generators include the following:

Oil pump failure: The oil pump cannot provide sufficient oil pressure normally, which may be due to wear of the oil pump, damage to the oil pump drive gear, or bending of the oil pump shaft.
Oil filter blockage: Oil filter blockage can cause a decrease in oil flow, thereby reducing oil pressure.
Low oil viscosity: Using low viscosity oil can cause a decrease in oil pressure.
Oil sensing plug malfunction: Oil sensing plug malfunction can result in inaccurate reflection of the actual oil pressure situation.
Excessive clearance between crankshaft bearings: Excessive clearance between crankshaft bearings can cause oil leakage, resulting in a decrease in oil pressure.
Improper or damaged adjustment of pressure limiting valve: Excessive or damaged adjustment of pressure limiting valve can lead to low oil pressure.
Low oil level: Low oil level can cause insufficient oil in the engine, thereby affecting oil pressure.
Oil contamination: Contaminants such as fuel, coolant, or water mixed into the oil can cause a decrease in oil pressure.
Overheating of the engine: Excessive temperature can cause a decrease in oil viscosity, affecting lubrication efficiency and ultimately reducing oil pressure.
Specific measures to address these issues include:

Check and repair the oil pump: If there is a problem with the oil pump, it is necessary to check and repair or replace damaged components.
Cleaning the oil filter: Regularly clean or replace clogged oil filters.
Use engine oil with appropriate viscosity: Ensure to use engine oil with the required viscosity.
Replace the oil sensing plug: If the sensing plug is faulty, a new sensing plug needs to be replaced.
Adjust the clearance between crankshaft bearings: If the clearance is too large, relevant components need to be adjusted or replaced.
Check and adjust the pressure limiting valve: Ensure that the pressure limiting valve is working properly.
Add engine oil to the appropriate level: Ensure sufficient oil reserves.
Replace contaminated engine oil: If the engine oil is contaminated, it is necessary to replace it with a new one and check the source of the leak.
Check and repair the cooling system: Ensure that the engine does not overheat and maintain an appropriate oil temperature.

Through the above measures, the problem of decreased oil pressure in Weifang generators can be effectively solved, ensuring the normal operation of the engine.
