Hi,
Long time no post - and first post in the Corrosion area.
Needing advice on some rather unusual corrosion on the rotor of a progressing cavity pump. I've been working with these more than 20 years now (applications support, tech sales and some service work) and not seen anything quite...
Hi,
Slightly unusual situation here in that we have a couple of 60s Triumph car engines running aftermarket fuel injection, with wideband O2 sensors for tuning and trim, but no catalytic converters.
One of these does not (yet) have hardened exhaust valve seats fitted and has started to...
Gentlemen,
This is a fair bit out there on this subject on the net already, but much of it low level and questionable.
In discussion with a colleague yesterday regarding his just-purchased 2019 Mercedes GLC. Something like 10 months old, less than 8000 miles. Former owner, the Mercedes...
My question concerns the now rather old Girling type 16 series of brake caliper used on many UK-built cars in the 60s and 70s.
It's a robust and reliable (if rather heavy) cast iron design with two opposing pistons of 54mm diameter.
The pressure seals are simple, rectangular section rubber...
I'm building up a Triumph I6 engine for a TR6. I've done a few of these in the past, but this one is more modified than any previous ones and has an aftermarket camshaft.
This is a 60's vintage OHV engine with the cam in the block. It has flat tappets.
I understand that the tappet centerline...
I've just fitted a pair of new aftermarket dual-rate coil springs to the front of my 60s Triumph. It's a double wishbone, coil-over-damper setup and the original spring rate was 220lb/in. The new springs are rated 330/530 lb/in and are considerably shorter than the OEM ones. The length isn't...
I'm trying to reduce leakage and general slobber from a Triumph 2.5L 6 cylinder engine. Actually in a '72 PI saloon but substantially the same as used in TR5/TR6. Mid 60's engineering with accountant intervention.
As standard they have only a single 1/2" outlet from the rocker cover, going to...
Whats the reason for manufacturers moving towards electrically actuated, push-button handbrakes these days?
Having recently had to deal with one as fitted to the VW Passat, I have to say that it alone would prevent me from buying/leasing what is otherwise a pretty good car - such a pain to use...
I have a client enquiry where a centrifugal pump specification shows a casing material of carbon steel and an impeller of Inconel 625.
Product is oily, highly saline produced water @ 105ºF. Chlorides shown as peak 145,783 mg/l, normal 78,679 mg/l trending to fall to something close to seawater...
I was recently working on a '96 Audi A6 Avant 2WD, ABS equipped. This has in-line restriction orifices located in each rear brake line where the caliper hose meets the hard lines. Being made from aluminium and located very much in the splash zone, these dissolve away quietly and eventually...
Gentlemen,
A wanderer from the pumps forum here so please excuse my ignorance.
I work for a progressing cavity pump manufacturer and elastomers are a key component used for the stators. We use various rubber types and grades to cater for different fluids handled. Among our selection used to...
