SPF-B Fuel Injection Pump Test Bench Internal Combustion Pump Testing Equipment

SPF-B Fuel Injection Pump Test Bench

The SPF-B Fuel Injection Pump Test Bench is specifically designed for performance testing of single fuel injection pumps used in internal combustion engines, particularly the 240 diesel engine. It integrates advanced control technology with a robust mechanical structure to ensure accurate and reliable testing results.

Main Functions

The SPF-B test bench is capable of conducting precise performance tests on diesel fuel injection pumps. It enables controlled fuel delivery and pressure simulation, ensuring accurate evaluation of pump efficieancy and functionality.

Structural Overview

The machine features a compact and durable structure:

• The base is constructed from welded steel plates, ensuring strength and stability.

• The outer casing uses high-voltage electrostatic spraying, making it scratch-resistant and wear-resistant.

• Integrated pump and oil tank design helps reduce operational noise.

• Internal components include a fuel tank, frequency converter, motor, belt pulley, and cam box assembly.

• The front panel includes a power control switch, while the rear houses the electrical distribution system.

• Operation is managed through a digital display interface for easy control.

Key Features

The SPF-B test bench stands out with its advanced and user-friendly design:

• Intelligent digital control system for precise operation

• Fast and accurate testing results

• Stable and reliable performance

• Easy maintenance and long service life

• Energy-saving and environmentally friendly operation

The injection pressure is generated by a 1.1 kW oil pump motor, supplying fuel to the injection pump. The frequency converter controls both the oil pump and the main motor speed, ensuring accurate fuel injection simulation.

A constant temperature fuel system minimizes data deviation caused by temperature fluctuations. All testing data is displayed on a touchscreen interface, and final parameters can be saved for future reference.

High-precision pressure sensors ensure stable and reliable readings. The control system continuously monitors electrical components and includes comprehensive protection features such as overcurrent, overvoltage, overheating, and overload protection. In case of abnormal conditions, the system will automatically shut down.
