in the pump housing, rotating at the identical speed in reverse instructions to execute
útfiere fan sûgen en ôffieren fan brânstof De twa rotors wurde stipe troch rollende lagers
in the finish addresses of the pump, rotating at higher speed and are kept at a
set relative place by a pair of timing gears. The end clearance among rotors and
end addresses are fixed by adjustable metal shims between the bearing housings and the
end cover at the set stop, which makes certain one-direction growth of the rotor when
temperature rises in the course of its procedure.
4 sets of inner seals (also known as piston ring) in the two conclude handles avert lube oil
getting into into the pump housing. The shaft seal at the front-stop cover, also named as
kader oaljedichting of asafdichting, foarkomt lekkage fan loft yn 'e pomphûs.
In buy to lessen temperature of the pump, all types of pumps (anticipate the two
smallest types) are geared up with a gearbox cooler and front-stop protect cooler.
Enerzjy wurdt oerdroegen fia in keppeling as V-riem fan 'e motor nei de driuwas fan
de pomp en dan by wize fan syngronisaasje fan fersnellingen nei de oandreaune as
