Lifting And Transportation Machinery Hydraulic Pump Test Bench With
Data Detection For Testing Hydraulic Motor
Description:
The pump motor test bench is mainly used for performance testing of
open pumps, closed pumps, and motors (as closed pump tests). As an
open platform, the system adopts modular design, and obtains the
basic data analysis and support of fluid, power and electrical
control systems through the combination of mechanical, electronic,
control and computer, so as to promote the rapid improvement of
efficiency and quality, so as to promote the scientific and
technological progress of enterprises and the improvement of market
competitiveness.
The hydraulic testing system designed by us has the following
characteristics:
★ The test system has high reliability under extreme working
conditions such as high speed and high pressure, and has a wide
range of test functions.
★ We have rich experience in pump motor testing, and can assist
users to complete the test process and judgment preparation,
matching system parameters and tooling design;
★ The design of the test system is beautiful in appearance, the
atmospheric design is in line with ergonomics, the operation is
comfortable, and the safety is good;
★ The manufacturing technology of the test bench is advanced, and
the test bench is processed as a whole to fully ensure the
concentricity and verticality of the connection and installation
mechanism;
★ The operation interface of the test system is graphically
designed for easy operation. The operation interface is embedded in
the hydraulic circuit diagram, and the status parameters in the
circuit are displayed in real time, and the operation status can be
monitored;
★ The measurement and control software has a high degree of
intelligence, which supports the testers to do secondary
development on the existing software architecture;
★ The test system has strong comprehensive scalability, and the
corresponding interface is fully considered in the design of the
hydraulic and control system, which is convenient for later
upgrading.
★ Proportional valves, flow sensors, high-pressure valve groups,
high-pressure filters and other key components adopt imported
first-class brands, with high performance and high reliability, and
fully ensure the test accuracy, response and stability;
★ The test system has its own fault diagnosis function, and the
system is stable and safe. It can automatically generate test
reports, print test curves, and automatically store test data for
future analysis and management.
