Pig Feeder - hydraulic modification

We received an enquiry regarding the hydraulics on a mobile pig feeder.  Our hydraulics engineer visited the site, where he made up the hydraulic hoses as required and fitted them.  The hydraulic valves were mounted as required.

In order to check the operation of the hydraulic system, our engineer connected his power pack to the machinery.  Once he was satisfied the hydraulic system was operating correctly, the power pack was disconnected and he left the site.

P & R Hydraulics offers an on-site service for customers based in East Anglia because we understand the need to reduce machinery downtime and keep costs to a minimum.  Our hydraulic engineer will travel to site, diagnose the problem and continually communicate with the customer regarding any necessary action.  Where possible a repair will be performed on-site, however, at times it is necessary for a hydraulic unit to be brought back to our in-house workshop for repair and test.

We will consider site visits further afield - please contact our Service Department with details (01603 424880).

Drilling Rig - Hydraulic Fault

Drilling rig
 

Our experienced hydraulic engineer was called out to site to investigate the hydraulic fault on a Hanjin P6000 drilling rig.


He removed the tank top filter lid and found the hydraulic oil to be contaminated with excessive amounts of brass and metal.  The hydraulic pump was disconnected for repair, the hydraulic tank cleaned and all filters removed.  The next job was to remove as much oil from the hydraulic system as possible.  The return filter assembly was cleaned and the return filter and small suction filter were renewed.  He cleaned the large suction

filter, as best possible.  The repaired hydraulic pump was re-installed and re-connected to the hydraulic pipes.



Our engineer left the site when he was satisfied with his work.  The customer was to fill the tank, run and check the hydraulic system.

Spool Valve inspection

A McConnell power arm spool valve was brought into our workshop for inspection.

Our hydraulics engineer inspected the valve.  In order to test it, all port adaptors were removed first.  The valve was connected to our in-house test rig and the mechanical actuators worked correctly with no leakage.  The spool valve was reassembled and returned to the customer.

No job is too small!  Our experienced engineers can inspect, repair and test a wide variety of hydraulic motors, pumps and valves using our in-house workshop and test rig.

Hydraulic repair on a Case Poclain 60PB excavator

A scrap metal merchant was having problems with his Case Poclain 60PB excavator, so he asked our hydraulics engineer out to site to investigate the hydraulics on the machinery.  The reasons for failure appeared to be a faulty pilot pressure valve and the secondary hydraulic pump was worn. 

A second visit was necessary in order to fit a replacement pump and valve whilst rebuilding the machinery, together with new hydraulic oil .  Also more tests were carried out, the main pump pressure was checked whilst the machine was hot and the pilot pressure was increased for the joysticks.

Our engineer left the site when he and the customer were satisfied with the work done.

hydraulic motor repair

Model No: MHA1400C107BV15

The owner of a Miami fairground ride sent the HTL hydraulic motor into our workshop for repair.  Our engineer dismantled the motor and found the shaft broken and the piston housing badly scoured.  All other parts were cleaned and inspected and renewed as necessary, together with a new shaft and piston housing.

Our engineer completed the delicate operation of re-assembling the motor and tested it on our in-house test rig, before returning back to the fairground ride owner.

Hydraulic spool valve inspection

A customer contacted us because they were having problems with an excavator and thought the spool valve was at fault.  The 10 bank valve was removed from the excavator - coloured cable ties were fitted to all inlets and outlets to ensure the valve would be re-fitted correctly.  The valve was brought into our workshop for inspection.  Our engineer cleaned and inspected the valve, and prepared it for testing on the test rig.  Preliminary tests showed that nothing was wrong with the travel sections of the valve.  After more thorough testing our engineer concluded the valve was not faulty and was therefore returned to our customer.

Later on our customer informed us that the problem was on another part of the excavator.

Site Visit - Hydraulic Power Pack Repair




Hydraulic Power Pack



Our engineer was called out to site to inspect a faulty hydraulic power pack.  He completely stripped the power pack and all the parts were cleaned and inspected.  The hydraulic tank was drained of oil and cleaned.

The inspection found the hydraulic pump to be badly worn and the filters were blocked.  A new pump and filters were fitted.  The hydraulic power pack was reassembled and the tank refilled with oil.

Before leaving the site our engineer checked the hydraulic power pack for operation and leaks.

Site visit - Powerscreen Conveyor

Our customer's powerscreen conveyor was not
working correctly.  Two hydraulic motors were
dismantled from the conveyor and brought into
our workshop for inspection.  One motor was
OK, but the other one was unrepairable and so
replaced with a new unit.

The motors were installed onto the powerscreen conveyor but still the machinery did not operate correctly.  So our experienced hydraulics engineer was called out to site to investigate.  He checked the flow and pressure of a hydraulic pump fitted to a powerscreen conveyor.  The front section of the pump failed the test procedure so a new pump was supplied and fitted.  When satisfied that everything was working correctly our engineer left the site.

Site Visit - volumetric concrete mixer hydraulic fault

Our hydraulics engineer was called out to identify a hydraulic problem on a volumetric concrete mixer.

The engineer inspected and watched the hydraulics operating on the mixer. He removed the water tank and inspection cover from the hydraulic tank. This enabled him to reposition the two suction filters. The inspection cover and water tank were re-fitted.

Our engineer checked the hydraulics were operating as required.
