Testing stand of fuel injection pump debugs test equipment as fuel injection pump, in fuel injection pump produce the effect with be worn main with the play in maintenance. In recent years, what apply as diesel engine is increasingly extensive, oil pump oil is improved of chew technology ceaselessly, the technical demand of production manufacturer of fuel injection pump and maintenance trade to testing stand of fuel injection pump is higher and higher also, the manufacturer home that causes the homebred testing stand with not much amount to also draws close to world advanced technique in succession.
1, current situation of product of testing stand of fuel injection pump
At present testing stand of pump of domestic fuel injection produces manufacturer since 80 time, the amount keeps basically stable, the breed of the testing stand product of each enterprise forms respect detailed to see next tables:
Frequency conversion of dc of slippery difference of hydraulic pressure of company name machinery
7.5 of of 7.5 5.5 of of 4 5.5 5.5 7.5 of of 7.5 5.5 of 11 5.5 11 15

Show in the watch, press timing pattern and classification of dynamical transmission way, the testing stand that domestic each manufacturer produces generally at present, the transmission gearshift that basically is clutch of slippery wrong type and communication transducer timing the product of two kinds of types. And produce testing stand of timing of mechanical, hydraulic pressure each have, two of dc timing, and its yield is quite low also, above 3 sort product always adds up produce per year a quantity to be not worth 10 thousand.
2, current situation of system of timing of motivation of testing stand of fuel injection pump
(Testing stand of gearshift of 1) mechanical roll
Mechanical turns gearshift testing stand is to use alterable means leather belt annulus will realize drive of fuel injection pump to persuade the infinitely variable speeds of axial rotate speed. This type testing stand the fifties end begins to be produced in home, because of its the structure is produced simply, easily, ever maintained an industry to have very big market in fuel injection pump, but efficiency of drive of this type product range of low, gearshift is narrow, satisfy the gush oil pump of form a complete set of diesel engine of high speed, high-power to debug hard, current and only a few this model testing stand, of the gush oil pump that basically is diesel engine of the small-power in waiting in the light of machine of tractor, project debug, this kinds of product already was belonged to wash out a product.
