The engine oil separator is specially designed to work with positive crankcase ventilation (PCV) systems. It is plumbed into the system and located between the vacuum sources and the crankcase. While pressure is being drawn out of the crankcase, it will be taken through the canister of the separator. While the oil is in the canister, it will run through several steel mesh and baffles. These meshes will then help to separate the moisture and the oil from the airflow. Next, the drained oil will flow to the bottom of the canister and the already cleaned air will continue to flow into the intake after which it will enter the engine again.
The grit washer is also created to perform the somewhat similar task. The mixture water, which contains several substances, like organic substance and grit are passed into the grit wash tank, and the organic matter gets suspended, and it floats off allowing the grit to settle gently at the bottom of the tank. The grit gets separated from the rest of the organic constituents by adding water. The separation is made even easier with the use of up-current technique and stirring device. Afterward, the grit gets removed from the tank, and it is then de-watered, after which it is discharged through the discharge screw, bringing an end to the grit washing process.
While a PCV system is sucking pressure from the crankcase, it will also bring out a fine mist of oil, and this can be included in the fuel-air intake charge of the system. This process can negatively affect the system, but its negative effect is not noticed early. Such negative effect can be completely prevented by using the engine oil separator. If the separator is not used, accumulation of excess oil will ensue, and this can cause an overall less power output from the system. Such situation can equally culminate to fouled spark plugs. The rate of combustion can also be greatly impaired. In some cases, harmful detonation had been observed. The use of the separator helps to prevent any of these issues from coming to the fore, thereby maintaining the life of the machine.
Grit washer comes in different forms depending on the manufacture. However, many of the types being sold today can be used along with the upstream coarse screen, and they have the capacity to reduce the organic content of the oil to volatile solids less than 3%. They can also easily adapt to several changing conditions. For improved hygiene, the machines are encapsulated. They have also found use in several municipal and industrial applications. The washer can be used as a reception station for grit from sewer by adding bunker at the upstream side.
The engine oil separator is made available in different sizes and shapes; the smaller sizes have been noticed not to have the same capability as the larger sizes. The larger versions are included with drains, which make it easy to remove the accumulated oil. Some other sets of separators come with the two-piece body, which can easily unscrew for easy draining of the oil.
The sizes of the engine oil separator can be provided in various forms like polished, anodized and natural canisters. With the help of the separator, the quantity of oil running through the PCV system can be monitored. The separator also ensures the oil does not contaminate the intake charge. The benefits are simply incomparable.
