CONTROLLED PARAMETERS To maintain the test fluid viscosity within prescribed limits, the test stand is equipped with a system to heat and cool the liquid and maintain its temperature at 40±1 °C. A specific 0-99.9 display indicates the temperature of the test liquid. A 2-stages filter (5μ) constantly clean the calibration liquid. The use of test fluid complying the ISO 4113 normative, as supplied with the test bench, is strictly recommended. EASY INSPECTION AND SERVICING In order to allows the maximum certainty of work without problems during the development process, all the features were dimensioned wider than necessary, so that maintenance of the SPP test stand is really minimal: service is limited to change calibration liquid and filters! The SPP test stand complies with the EU directives for user's safety as during work as during service (CE marking). BODY AND DESIGN SPP design is really simple: during development, all the efforts were focused to the functionality rather than to the style. The body is a steel structure, closed by removable panels for inspection and service. The test bench bed is a cast iron for high stability, during tests. The working plane is self-draining, with a proper recovery collector (20 litres capacity), separated from the main tank (35 litres capacity, for a total capacity of 55 litres).

2. SPP test benches models are suitable to calibrate of fuel injection pumps for diesel engines requiring fuel delivery up to 600 mm³/injection/cylinder (only SPP208S and 312S; the other models up to 300) mm³/injection/cylinder at full load. An SPP test bench is a traditional solution developed as a modular base able to be upgraded with proper equipment and also make easy the testing of the new electronically controlled injection systems. The following models are available on DETEQ standard production program 8 cylinders: 12 cylinders: SPP208 (5.5 kW) SPP212 (5.5 kW) SPP308 (7.5 kW) SPP312 (7.5 kW) SPP208S (9.2 kW) SPP312S (11 kW) Each model has the following described features; on request, customized versions can be developed. STATIC CONDITIONS The supply and control of calibration fluid to the pump under test and the measurement of its performances comply the ISO 4008/2 rules, to establish appropriate conditions in the hydraulic delivery circuits and to make all the necessary measurements in order to test and adjust pumps to manufacturer's test specifications. DYNAMIC CONDITIONS One AC electric motor drives the injection pump coupling head, by a pulley and toothed beld. The speed stability of ±1 RPM is reached through the flywheel, whose inertia is 0.75-1 kg/m². The electronic unit allows to have the 200% power of the en g ine at the same s p eed, p reviousl y runnin g. This technology allows the 40% recover of the power between the pump and the engine; by this result, the SPP test stand reduces electrical consumptions (variable cost) and power installation (fixed cost), enhancing the workshop inexpensiveness. The test bench is equipped with anti-backlash coupling, with protection cover. The noise generated by the test bench itself is reduced to very low levels. CLAMPING THE PUMP HOUSING The distance between the test bench-bed top face and the centre of the test bench drive-head is 125 mm. The centring system with very restricted tolerances allows the simple and easy clamping of the pump housing and the correct alignment of the pump camshaft. The standard equipment of the SPP test stand includes brackets and flanges for the most common kinds of injection pumps; others are available on request. DRIVING THE PUMP The engine is controlled through an electronic unit allowing the speed adjustment (from 50 up to 3500 RPM), by rotating the 2-levels speed control (one for fast, the other for a more accurate) and immediate stop of the engine. The RPM digital display is 4 digits, autoranging: 0.01, 0.1, 1 RPM. The sense of rotation can be left or right, by selecting the proper command on the control panel. For high accuracy of timing test, the graduated disk presents division each 0.5-degree on the total c ir cu mf e r e n ce a nd i t i s equipped with magnifier. C ALIBRATIN G THE P U M P Pro g rammin g the testin g c y cle is reall y sim p le: b y means of the UP and DOWN ke y s, the user can increase/decrease b y multi p les of 50, u p to 1000 shots, throu g h the p ro p er 0-1000 di g ital dis p la y . Once the testin g c y cle starts, the calibration fluid is now discharged directly into the graduated glass tubes ( 0-44 cc and 0-260 cc capacity ) , for delivery measurement . When the p ro g rammed number of shots is reached, automaticall y the s y stem p revents an y more fluid from reachin g the test tubes, to let checkin g t h e level of each c y linder. To start a new test, it is necessar y to turn over the test tubes and let them drain before re-usin g. Five manometers are installed, to control : - vacuum/low pressure ( -1/0/+5 BAR ) - high pressure ( 0-60 BAR ) - transfer pressure ( 0-16 BAR ) - box pressure ( 0-2.5 BAR ) SPP TEST BENCHES for diesel fuel injection pumps THE SPP TEST BENCHES FAMILY
