2. Causes of 2641A405 Power Diesel Pump Being Damaged
- Failure to follow the engine maintenance manual during disassembly or installation may result in damage to the power diesel pump.
- The fuel oil used for the vehicle does not meet the standard cause damage to the power diesel pump, such as: the water content in the fuel oil exceeds the standard, iron powder, aluminum powder, sulfide impurities exceed the standard, etc.
- The engine is not regularly maintained according to the engine maintenance manual (please refer to the vehicle maintenance manual for the maintenance mileage). For example, failure to replace the lubricating oil of the engine system for a long time will cause abnormal wear of the engine, excessive exhaust gas volume or a large amount of carbon deposits inside the engine. The filter is not replaced during maintenance or the replaced filter cannot reach the original filter standard. all above reasons can cause damage to the power diesel pump.
- The abrasion of the oil pump produces iron powder and aluminum powder enter the power diesel pump and cause damage to the power diesel pump.
- The deformation and abrasion of fuel tank result in iron powder or aluminum powder entering the power diesel pump and causing damage to it.
- The power diesel pump is damaged due to replacement or adjustment of the relevant parts of the power diesel pump. For example, the valve clearance does not meet the standard after the engine is repaired, the replacement or modification of the wiring harness connected to the power diesel pump fails to meet the original standard.
- The engine is overheated and overloaded for a long time working results in damage to the power diesel pump.
- The power diesel pump will be damaged naturally at the end of its working life.
- The power diesel pump is magnetized (power diesel pump parts’ magnetic exceeded) causing the power diesel pump to not work properly.
- Before replacing the power diesel pump, please check the engine parts carefully according to the engine maintenance manual to avoid the power diesel pump being damaged again after replacement.
3. 2641A405 Power Diesel Pump Storage Standards
(1) Choose a suitable storage place
The warehouse and cargo yard where the power diesel pumps are stored should be kept clean and dry, and away from the factory buildings that generate harmful gases and dust; do not mix with acid, alkali, salt and other substances; the storage place should have a good drainage system; the cargo yard should be flattened with gravel or furnace ash etc. to enhance the water permeability of the surface layer to keep the reservoir area dry.
(2) Strict storage requirements
Strict inspections should be carried out when the power diesel pumps are put into storage, the surface cleaning work should be done well to remove water traces, oil stains, ash and other dirt, remove the rust and do anti-rust treatment in time. Packaged power diesel pumps must be protected from damage.
(3) Keep the warehouse dry and do moisture-proof work
The relative humidity is usually below 70% for the power diesel pumps placed in the room, and the corrosion of the power diesel pumps is significantly reduced.
Fuel pumps must be stored in the warehouse, and they are forbidden to store in the same warehouse with commodities with high water content.
(4) Reasonable stacking
After the power diesel pump is exposed to rain, the corrosion rate will increase significantly. The purpose of sealing is to isolate the power diesel pump from rainwater and humid air, so the warehouse window should be checked in time to avoid rainwater entering the warehouse.
If the power diesel pump package is damaged, it should be repaired or replaced; when the package is damp, the packaging material should be dried; if the original anti-corrosion and oil applied at the factory is found to be damaged or dried up, it should be cleaned and re-applied oil in time.
- It is forbidden to leave the power diesel pump exposed in the air for a long time.
- It is forbidden to store acid, alkali, salt and other substances together with the power diesel pump.
- The unpacked power diesel pump must be rust-proof during secondary storage.
