摘要

"Constructive disposition introduced in equipment of the type test bench and adjustment of injection pumps of automotive engines powered by diesel oil.Represented by an evolutionary solution whose technical specification of test stand and control (a) allows it to operate with low noise level.High torque across the range determined by the electromechanical motor (1), which can be used with number of poles high, with continuous variation of rotation.The stability of rotation and power factor close to 1, with overloading was very low, where the automatic control results in extending the useful life of the box exchangeThanks to its low wear, and in addition the motor has no brush, no reservoir of hydraulic oil.For this operating condition is obtained, the new test stand and control (a) is composed of a speed control system (S1), a system of type 'tachometer' (S2); a system of acionEnhanced command (S3); new spinning system (S4), a security system (S6), a valve system (LDA) (S7), and an electronic system for opening and closing the chute (S5).Where such systems make feasible thanks to the use of a component frequency inverter (C8); a remote control (C3); an emergency key (C7); a framework of cylinders (C6); a panel elu00e9tricThe (C1), a set of high and low pressure valves (C2); a heat exchanger (C4) with valves with control eletroeletru00f3nico and a processor bivolt (220V / 380V) (C5)And the operation of all the equipment is carried out by the local computer (C9).
