Diesel Engine Fuel Pump 9520A354G Featuring an integrated die-cast pump body structure, the internal oil circuit design is simple and streamlined, resulting in low pressure loss and a fuel delivery efficiency of over 95%. Core components are made of wear-resistant alloy materials and precision-ground to ensure uniform gaps between moving parts, keeping operating noise below 70dB and providing quieter working conditions in the workshop. The pump integrates an intelligent temperature control system that automatically adapts to different operating temperatures, preventing issues caused by excessively high or low oil temperatures from affecting fuel supply stability. The optimal operating temperature range covers -20℃ to 80℃. The sealing design employs a multi-layer composite oil seal, effectively preventing fuel leakage while also possessing excellent anti-aging properties, extending service life. Its modular maintenance structure facilitates disassembly, cleaning, and parts replacement, reducing maintenance difficulty. Combined with regular oil cleaning and filter replacement, it can achieve ultra-long continuous operating times.

FAQ
Q: How does this oil pump adapt to industrial equipment with different pressure requirements?
A: By adjusting the pressure adjustment knob on the top of the oil pump, the working pressure can be precisely set within the range of 400-800kPa to adapt to the power requirements of different equipment. When adjusting, it is necessary to use the equipment's pressure gauge to ensure that the pressure value is stable within the equipment's rated range to avoid overpressure operation.
Q: What should be done in case of a sudden supply interruption during industrial production?
A: Immediately stop the equipment operation, check the fuel level and filter blockage, quickly clean the filter or add fuel, and then loosen the vent valve to purge air from the pipeline before restarting. If supply interruptions are frequent, check the fuel quality or the status of the check valve inside the pump, and replace the filter element and seals if necessary.
Q: What precautions should be taken when restarting after a long period of inactivity?
A: Before restarting, inject anti-rust oil, check the pump body for rust, and ensure the rotating shaft is flexible. After installation, first run it under no-load for a short time to confirm there are no abnormalities before gradually increasing the pressure, avoiding direct full-load operation that could cause component wear.
