Introduction
JHDS-4 injection pump test bench is a new designed test bench based on the advanced foreign technology and modification. It adopts the most advanced technology of frequency conversion, with the advantages of wide speed regulation, steady performance, big output torque, ultra-low noise and protective multi-functions. The test bench uses the digital technology to indicate the rotation speed, oil-measuring counting and temperature of supplying oil clearly and reliably with high precise of control. The test bench also has compact structure of motor and work table. The main motor is connected with the dial directly, which ensures the assembly precise of the main shaft with the characteristics of high precise, low noise, good reliability and long life. The test bench is of ten sets of preset systems of rotation speed, which not only saves the times to adjust pumps, but also improves the working efficiency with rapid and convenient operation. It is the most ideal product for companies to produce and repair pumps and beans.
Features and Usage
Ø The main shaft adopts the frequency conversion to regulate speed, with the range of 0-4000 rpm.
Ø The oil-measuring counting and rotation speed is indicated by 4 digits.
Ø 10 sets of preset system of rotation speed.
Ø DC power of 12V/24V.
Ø The structure is compact and steady.
Ø The shell is sprayed with the static electronics, elegant and fertile.
Ø The oil-collecting tank can rotate left-right, and be lift or lowered.
Ø The test bench is equipped with emergency stop switch.
Ø It adopts the frequency converter of high performance and reliability.
Ø It has the protect of lack-pressure, over-pressure, overheat, and overload.
Ø Ultra-low noises.
