By adopting high performance/low noise inverter and advanced technique, COM-F fuel injection test stand has more and more advantages, such as: wide ranges of adjustment speed, stable speed, large torque, easy operation and so on. The test stand uses digital indicators to display speed, count. The COM-F range of test stands will (depending on the power specified) test most inline and rotary diesel pumps in use for on-highway and industrial applications.  COM-F 5.5KW, 7.5KW, 11KW and 15KW available. FEATURES Changing frequency changing rotation speed continuously; Low fall of rotational speed and high output torque; High precision; The function of over voltage and overload protecting; Low noise; Digit-display rotation speed, count and air pressure; Built-in air resource. FUNCTIONS Measurement of the delivery at various rotation speeds; Checking of each line's injection timing with static; Checking of the mechanical speed governors; Checking of the electromagnetic valve of distributor pump; Checking of the pneumatic speed governors; Checking of the pressure compensators (LDA); Checking of the vacuum capacity regulators; Checking of sealing of the fuel injection pump body.
