Specifications

Automatic hydraulic motor test bench is designed and manufactured in accordance with national standards for type testing of hydraulic motors , hydraulic motors can test a variety of dynamic and static performance . Test range , test items, test requirements in line with GBT 17491-1998, GBT 20421-2006, JBT 10829-2008 other relevant national standards, testing and test control accuracy : B or C grade . Automatic test bench hydraulic motor is a hydraulic motor manufacturing and repair business the most important testing equipment.

Automatic hydraulic motor test bench : mainly by the drive motor , control valve and test , test measuring devices, cooling tank , consisting of data processing and recording the output section , etc., using electric proportional displacement hydraulic pump source to meet all kinds of different speeds test conditions of the hydraulic motor , pump with electro-proportional load displacement pump to suit different subjects under the desired motor speed traffic loads , load pressure relief valve controlled by a proportional . Selection of the current advanced control valve proportional control device , while configuration manual control device , so you can use the computer to automatically control and detection tests , you can switch to manual control and testing . Pressure, flow, speed and torque measurement methods using both digital and analog , digital computer to facilitate the collection, collation and recording , analog control for easy on-site observation . Cooling water tank is done by the cooling unit , full power operation of the hydraulic motor to meet the requirements . Test bench can be designed and developed to meet the requirements of different users according to customer special requirements personality
The Company fully automatic hydraulic motor test bench features:
Highly integrated function valve stations , most of hydraulic components and sensors each functional module are integrated on the same valve block , reasonable layout of each function valve station on the pump station and the test bench , easy routine maintenance and repair ;
 working medium to support multiple types of hydraulic oil ;
 independent temperature control system, the oil temperature control within ± 1 °C;
 Built-in filtration system 3μ , filtering accuracy NAS1638 Level 5 (ISO4406 14/11 level) ;
 with automatic and manual test , easy to switch between the two modes .
 computer subsystem uses Intel Core2 Duo E6600 processor , RAM, and 16 high-speed data acquisition card 1GB NI PCI-6229 or PCI-6259;
 Simple , clear graphical test interface , the operator does not require very specialized knowledge does not need training ;
