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 will Control_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.
