Biomass hydraulic power unit inspection

Our on-site hydraulic engineer was called out to inspect a biomass hydraulic power unit.  The valves and hydraulic pump were removed from the hydraulic power unit and taken back to P & R for inspection in our workshop.  No faults were found during the test procedure on the valves.  The engineer returned to site together with the tested valves, a replacement hydraulic pump and coupling.  The hydraulic power unit was reassembled and checked for leaks and operation.  Once satisfied that everything worked OK, our engineer left the site.

P & R Hydraulics is attending LAMMA 2015.

For those that don't know, LAMMA is the UK's largest farm machinery, equipment and agricultural services show.  Now in its 34th year, and held in January each year with over 900 exhibitors, LAMMA is free to attend and regularly attracts over 40,000 farmers from around the country and overseas.  For anyone seeking ideas on how to make improvements to their agricultural equipment fleet, it's certainly the place to be on 21st to 22nd January.

We will be co-exhibiting with one of our premium partners, Hy-Pro, in order to showcase their range of hydraulic valve products and our valve maintenance services.

In addition, we will also be promoting the very latest hydraulic motors, pumps and valves from Parker Hannifin, Turolla and Danfoss.  With such a wide range of products available, together with our long demonstrable track record of experience, P & R have got the agricultural sector covered!

As well as one of our account management team, our Technical Director, Justin Gill will be there together with Maria Barham-Brown, our Financial Director.

Danfoss Power Solutions course

As an official distributor for Danfoss Power Solutions, P & R Hydraulics has access to resources that include training courses.  Justin Gill and Fred Edwards of P & R Hydraulics recently attended a Danfoss  Power Solutions course titled “Failure Analysis and Repair” at their production plant in Neumunster, Germany.  The five day course was for technicians who have at least two years experience of repairing/servicing Danfoss Power Solutions products. 

The following products were covered:-

·         S90 Pumps and Motors, S51, H1 Pumps and Motors

·         S45 (open circuit pumps)

·         Steering

·         Large, medium and small orbital motor product lines

·         PVG16, PVG32, PVG100 and PVG120

Both Justin and Fred have gained vast knowledge of Danfoss Power Solutions hydraulic products over the years, but felt the course served as a good refresher and was worthwhile attending.   They also found it very informative talking to the other delegates and sharing experiences.

P & R Hydraulics has an in-house workshop and test rig which enables us to repair, inspect and test hydraulic pumps, motors and valves.   New products can be supplied if the original unit is unrepairable.  For more information on our repair service please contact us on 01603 424880.

The following Danfoss parts were used in the assembly of the valve:-

155L2150   Name plate
155L7504   Spring
157B0008   End cover
157B2190   Shock valve
157B3171   Actuator
157B4228   Actuator
157B5110   Inlet cover
157B6230   Worksection
157B7002   Spool
157B8002   Assembly Kit

P & R Hydraulics Ltd can supply items individually or as an assembled hydraulic valve. This valve can also be multi-functional with more working sections. The PVG32 load independant valve can be used for applications with flow up to 130 l/min and pressures up to 350 bar. We can also assemble and supply Danfoss PVG100 and PVG120 valves.

Commercial spool valve DVA20 repair

Commercial spool valve DVA20 repair

Before any inspection could take place the DVA20 spool valve had to be cleaned of excess dirt. The valve was then dismantled and all parts cleaned.  Our engineer inspected the parts and found the spools to be pitted, the fastener seized inside the worksection, the seals were stiff and the detent kit damaged.  This was reported to our customer, who requested that only the seals should be renewed.  The valve was resealed (as per our customer's instructions), reassembled and tested on our in-house test rig.  The resealed DVA20 spool valve was returned to our customer in a much cleaner state, but without a warranty given.

P & R Hydraulics has an in-house work shop and test rig, which enables us to inspect, repair and test most makes of hydraulic motors, pumps and valves.  Please contact our Service Department for more details - tel: 01603 424880.

Danfoss PVG32 valve repair

A Danfoss PVG32 valve was brought into our workshop because the customer had deadheaded it.

Our engineer dismantled the valve and cleaned all parts. Upon inspection he found the electrical actuator (157B4033) only worked in one direction and the mechanical actuator (157B3171) was cracked.

The valve was repaired using the following new parts:-

157B8001 Assembly kit
157B3171 Mechanical actuator
157B4997 PVE seal kit
157B4033 Electrical actuator

The repaired PVG32 valve was tested and returned to our customer.
