On the domestic fuel pump test rig development trend

Fuel pump fuel pump as a test bed debugging test equipment, fuel pump in the manufacture and maintenance play an important role. In recent years, with the increasingly widespread application of diesel engines, pumps oil Tsui technology improvements, maintenance and fuel pump manufacturer on the fuel pump test rig industry the technical requirements of increasingly high, which few domestic manufacturers of the test rig also have to move closer to the world's advanced technologies.

(1) mechanical rotational speed test bed
Mechanical rotational speed test bed is to use variable pulley advised to achieve fuel pump drive shaft speed the CVT. The type of test bed in the late 1950s began in the domestic production, its structure is simple, easy to produce, and fuel pump maintenance industry in a large market, but the transmission of this type of product is inefficient, variable scope is narrow, difficult to satisfy the high-speed, large Diesel fuel pump power of debugging support, only a small amount of this type of test rig is targeted mainly tractors, construction machinery, such as small and medium-sized power of the diesel engine fuel pump tests, such products already out products.
