Tees Cottage Pumping Station - beam engine, governor and flywheel
This is the site's preserved Woolf compound beam pumping engine that was installed in 1904. This was the third beam engine on the site, the earlier two dating from 1849 and 1853. This part of the site was designed by T & C Hawksley of London, the engine was designed by Glenfield and Kennedy of Kilmarnock and erected by Teasdale Brothers of Darlington. It is believed that the major components were made by companies in Leeds and Manchester.
The beam engine was rated at 140 horsepower at 16 revolutions per minute with steam at 100 pounds per square inch. This is a view of the flywheel and the centre loaded (Porter-type) governor. The governor actuates a throttle valve and is mounted over the crankshaft. The flywheel is cast in two halves, is 21' diameter and weighs 14.5 tons. The flywheel is there just to store and give out energy to smooth the engine's motion and ensure the crank passes the top dead centres. All the engine's power is expended in the water pumps connected to the beam (plus some used in overcoming friction and working the air pump).
