CRS-618C common rail test bench

The CRS-618C high-pressure common rail test bench is the latest integrated equipment developed by our company to test the performance of high-pressure common rail pumps and injectors. It can test the performance of various manufacturers’(BOSCH, DENSO, DELPHI, SIEMENS, CAT) pumps and injectors as well as piezoelectric injectors. This equipment completely simulates the principle of the injection system of a high-pressure common rail engine. The main drive adopts advanced frequency conversion speed regulation technology, with large output torque and ultra-low noise. The common rail pump and injector are tested using imported flow sensors, and the test speed is fast, the measurement is more accurate and stable; it can be grafted with EUI/EUP system, and can detect the CAT 320D common rail pump. The oil pump speed, injection pulse width, oil volume, and rail pressure of the test bench are all controlled by an industrial computer in real time to collect data. The 19″ LCD screen displays more clearly, with more than 4,000 kinds of built-in debugging data that can be queried and printed (optional). The work is reliable and stable, and the control accuracy is high. The shell is processed and manufactured by CNC equipment, which is beautiful and durable.

This equipment can realize remote diagnosis of faults, making maintenance faster and more convenient.
