The role of the oil pump
Oil pump is a key component essential to the normal operation of
the engine. The role of the oil pump is to press the oil in the oil
sump to the oil filter and the lubriing oil channel after
pressurization, so as to lubrie the main moving parts of the engine
and make the oil get filtered.
When the engine is working, the oil pump keeps working, so as to
ensure that the oil is circulating in the lubriing oil path. Under
various working conditions of the engine, the oil pump should
ensure the supply of sufficient lubriing oil. As the speed of the
oil pump is proportional to the engine speed, the oil pump has the
worst oil supply capacity at low speed. So we design the oil pump
with sufficient oil supply capacity at low speed in mind.
The working principle of oil pump
When the engine is operating, the timing gears of the crankshaft
rotate the oil pump. The rotor teeth are designed in such a way
that when the rotor is turned to any position, the gear lines
always make point contact with each other. In this way, a closed
cavity is formed between the inner and outer rotor, and when it is
turned from the oil inlet, the volume increases and a vacuum is
generated, and the lubriing oil is sucked in through the oil inlet;
when the cavity where the lubriing oil is sucked in is connected to
the oil outlet, the volume in the cavity decreases and the oil
pressure rises, and the lubriing oil is pressed out from the
outlet. When the engine keeps running, the oil pump also keeps
running, forcing the lubriing oil to circulate according to the
prescribed path; when the oil pump pumping pressure is too big or
too small, the pressure limiting valve opens or closes.
