The importance of air oil separator

The role of air oil separator

Forced to the valve chamber, crankcase pressure relief! --- This is the most important role!

Piston ring no matter how sealed, it also has a gap, not to mention its own interface, although the two seal ring and an oil ring interface are staggered, but also can not stop the cylinder hybrid explosion strong pressure, there will still be some The high pressure exhaust gas rushes into the crankcase.

Therefore, now the car are equipped with crankcase ventilation system. Do not underestimate these emissions, the vast majority by the combustion of hydrocarbons, these emissions will dilute, contaminated oil, and corrosion of engine parts. Especially at high speed, the serious blow-by gas will cause the piston ring and the cylinder block between the oil phenomenon, of course, the direct discharge, then it is also very polluting the environment.

The purpose of the crankcase ventilation system is to guide the exhaust gas into the intake manifold and then through the distribution system into the cylinder secondary combustion, because they are gas, to fuel-efficient purpose, but the main purpose is to reduce the blow-by gas on the engine damage , While avoiding its emissions into the atmosphere pollute the environment. In the Chery car, single-point vehicle room PCV system, multi-point car should be fixed vents, the specific is to rely on oil and gas separator to achieve. There is a friend to check the car or in order to avoid the always clean oil and gas separator, simply put the valve chamber lid connected to the oil and gas separator pipe directly pull the crankcase emissions to the atmosphere inside, it is wrong! We see air oil separator, is four tubes, two into, two out! Respectively, connected to the upper air filter, the valve chamber cover (the two are air), and the lower air filter, into the steam.

RUI’AN QIANGXING air oil separator is your best choice!

Rolls-Royce expands permanent magnet thruster range

2016-09-30 09:48:36 | 日記
Rolls-Royce has successfully completed a year of sea trials of its new Azimuth Permanent Magnet Thruster which it made available to customers for the first time at this year’s SMM exhibition.
The thruster has been in operation aboard the 31m long research vessel Gunnerus, owned by the Norwegian University of Science and Technology (NTNU) since April 2015 and has clocked up 3000 hours of operation.
Gunnar Johnsen, Rolls-Royce, Head of Electrical System R&T – Marine, said: “We expect to see a reduction of 50% on the maintenance costs and in case of any maintenance, our condition based monitoring system shows you the current health of the units and allows you to plan maintenance ahead.”
Over the course of the trial researchers found a high motor efficiency, 97% at nominal speed and high over the whole load range, an increase in bollard pull (+20%) and speed – approximately one knot over the range for the same input power – with airborne and structural noise readings lower or similar to previous performance. Hydro acoustic noise was also improved.
The thruster has fewer moving parts than conventional thrusters. It combines a ring-type permanent magnet for motors, propeller and nozzle in a tightly integrated propulsion unit. Simple bearings in the rotor hub carry all loads and only a small oil circulation pump is required.
This system carries less oil than conventional thrusters reducing the risk of environmental damage if spilled. The system uses biodegradable oil, which has the Vessel General Permit (VGP) for Environmental Acceptable Lubrications (EAL) approval.
