The test bench for injection units of vehicles powered by engines, automotive diesel oil

摘要

The test bench for injection units of vehicles powered by engines, automotive diesel oil, which comprises a cabinet (1), containing a mounting of the coupling (3) which simulates the head of the truck, a cylinder (4) which displays the level of diesel oil to be injected; UA NDA is a pneumatic piston (5) which makes the rate of injection of the unit, a gaveteiro (6),A lung compressed air 97), an external compressor (8), a non-return valve (9) which allows a constant airflow, pressure gauge (10), and a pressure regulating valve (11); the workbench has an oil tank (12) which simulates the injection of oil. In the test, where There is a level sensor (13), the lid supply (14), heating resistor (15).The oil pump fuel (16), a temperature sensor (17), a radiator (18); the electronic circuit contains a power stage circuit (23), (24), PLC (19) and HMI (20) operated by the operator of the workbench, this circuit simulates the module of the truck and selects the voltage electric be tested in CAD The injector; in the posterior region of the cylinder (4) there are two outputs of the oil level sensor (34), (35),Exhaustion valve (36); in the base below the cabinet (1) there are four feet (37) and an electrical connection (38) that feeds the bench with energy.
