How Long Does It Take to Replace a High-Pressure Fuel Pump?
1 Answers
Replacing a high-pressure fuel pump takes about 2 hours. Introduction to High-Pressure Fuel Pump: A high-pressure fuel pump is a device used to provide tensioning power for prestressed jacks during tensioning operations. The specifications of this device are as follows: ZB2 multiplied by 2/50, where ZB is the device code, the first 2 represents the rated fuel supply per minute, the second 2 indicates the number of fuel supply circuits, and 50 is the rated oil pressure. Applications of High-Pressure Fuel Pump: The primary use of a high-pressure fuel pump is as a power source for hydraulic devices such as jacks, heading machines, extruders, and cotton gins. The installation sequence for a high-pressure fuel pump is as follows: During installation, to prevent debris from entering the machine, all openings on the unit should be covered. Place the unit on a foundation with embedded anchor bolts, and use paired wedges for alignment between the base and the foundation. Align the concentricity of the pump shaft and the motor shaft, allowing a deviation of 0.1 mm on the outer circumference of the coupling. The gap between the two coupling surfaces should be maintained at 2-4 mm, with a uniform gap and a tolerance of 0.3 mm. After connecting the pipelines and confirming the motor's rotation direction, attach the coupling and recheck the shaft's concentricity. After 2-3 hours of actual trial operation, perform a final inspection. If no issues are found, the installation is considered qualified.
