Hydraulic Test Equipment > Function Test Rig > Pressure Test Beds

Bonaprene Fluid Power design and manufacture hydraulic pressure test beds
for a wide range of customer products. In this type of testing the product
is of a form and size that it is most practical for the customer to bring 
the product on or within the testing equipment. A few examples of products 
Bonaprene Fluid Powers hydraulic pressure test beds can check are hydraulic 
pipes and hoses; manifolds, brake systems and sealing interfaces in industries 
such as mining, aerospace, earth moving equipment and automotive.

For the high pressure hydraulic testing of welded pipe assemblies various 
pipe diameters, designs and lengths can be accommodated. The assemblies for 
testing are connected to the inlet and outlet distribution manifold via short 
flexible hoses and quick release couplings. Each manifold block can consist of 
14 ports 7 on the front and 7 on the top. Test points are selectable via a 
solenoid valve in the inlet manifold block. A flow control orifice in each 
pipe leg ensures equal flows distribution

The oil reservoir underneath the hydraulic test bed are fitted with an oil 
level gauge, drain valve and two position oil level switch, electric motor/  
pump set, I count analyser, filters and associated control valves located 
adjacent to the reservoir. 

The hydraulic pressure test bed incorporates an electric motor driving a 
double gear / piston pump. The gear pump is used for fast filling of the 
pipes and the piston pump for the pressure test.

The manifold blocks are sized to accommodate various pipes with flow control 
valves on the inlet manifold to ensure even filling of the pipes. Filling and 
pressure testing take place simultaneously for all pipes. 

The test pressure is infinitely variable by means of an electrically operated 
proportional pressure relief valve and proportional amplifier card, pneumatically 
purging and measured by means of a pressure transducer. 

PLC Control:

A PLC is housed within its own enclosure for the hydraulic test bed and willControl_screen_web_1
incorporate an HMI touch screen that displays pressure reading, temperature, 
high/low oil level and particle readings. Two log options are available one for 
the user operator and one for an engineer / maintenance access screen. Both are password protected. The PLC stores all the data readings ready for downloading via an either net port to a PC and print out test results from the PLC.

On entering a part number relating to the pipe being tested the PLC sets the 
predetermined pressure required using proportional valves.
