7. YST380 hydraulic test stands for repairing hydraulic pumps and
motors
Hydraulic test stands brief introduction:
YST380 hydraulic test stands are used for checking and proofreading
products that include hydraulic pump, hydraulic motor, hydraulic
cylinder and valve. It also can conduct hydraulic system's
breakdown diagnosis. These products are researched and produced by
ourselves, so we could customize according to customers' needs.
Hydraulic test stand is divided into five varieties: hydraulic pump
test stand, hydraulic motor test stand, hydraulic valve test stand
and hydraulic cylinder test stand and comprehensive test stand.
This series of test stand has designed various configuration, for
example: proportional control system, digital display system,
variable frequency speed regulation system and computer measurement
and control system etc. The user can select it according to your
need.
Hydraulic test stand test items:
1. Functional requirements : it is used for testing hydraulic
pumps,high speed motors,low speed motors,hydraulic cylinders and
all kinds of valves
2. Pumps and Motors Model Range: (according to part A’s request)
3. Test Item:
1). Displacement checking testing : No-load Pressure,determination
of displacement.
2). Volumetric Efficiency/Total Efficiency Testing: Under the rated
conditions,test volumetric efficiency and total efficiency.
3). Overload Testing: Max.displacement,Nominal Speed,125% of the
rated pressure, or max. pressure operation more than 1 minute
4). External Leakage: in the above testing, Check the leakage of
sealing parts.
