Description

Engine crankcase

Technical Field

The utility model belongs to the technical field of the clean processing equipment that filters of engine lubrication machine oil, a engine crankcase is related to.

Background

The lubricating oil system on the engine is generally mainly composed of equipment such as an oil tank, an oil pump, an oil cooler, an oil filter and the like, valves, pipelines, instruments and the like, and is connected with each lubricating point of the machine, an oil hole and an oil groove of a bearing bush, a bearing box and a crankcase through pipelines to form a set of complex lubricating oil system. In the daily use of generator lubricating oils, some users find visible fine impurities and precipitates in the oil, such as: when the engine oil flows, impurities or precipitates such as silt, dust, scrap iron, fibers and the like can be attached; and (II) gas, moisture and other oxides which are not burnt out in the cylinder enter a crankcase through a gap between the piston and the cylinder wall, so that the crankshaft is abraded, metal powder is generated, and the metal powder is mixed with impurities to generate sludge in the past. These impurities and precipitates flow with the lubricating oil, and block the oil holes, reducing the degree of lubrication of engine parts, causing severe wear.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide an engine crankcase makes the impurity in the engine oil deposit, realizes the upper and lower layer separation of impurity and oil to make the clean lubricating oil in upper strata flow into the oil pumping storehouse.

In order to achieve the above object, the basic scheme of the utility model is: the utility model provides an engine crankcase, includes the crankcase body, is equipped with oil return oil storage bin in the crankcase, the vertical baffle of bottom fixedly connected with in the oil return oil storage bin, the baffle is divided into the oil return oil storage bin and is precipitated storehouse and oil pumping storehouse, and precipitate storehouse and oil pumping storehouse are in a certain high department intercommunication in the distance bottom.

The working principle and the beneficial effects of the basic scheme are as follows: the return oil storage bin is divided into a settling bin and an oil pumping bin by the partition plate, so that the settling bin and the oil pumping bin are ensured not to interfere with each other. The lubricating oil of output gets into and deposits the storehouse in the engine, deposits in deposiing the storehouse, and the impurity deposit is in the bottom of deposiing the storehouse, and lubricating oil is located the upper surface of impurity. When the oil in the settling bin is accumulated to a certain height, the lubricating oil in the settling bin enters the oil pumping bin from the communicating part of the settling bin and the oil pumping bin to complete the separation of the lubricating oil and impurities. And the lubricating oil entering the oil pumping bin enters the equipment again to lubricate the equipment.

Furthermore, a gap is formed between the top of the partition plate and the top of the oil return and storage bin.

Utilize this clearance as the intercommunication department that deposits storehouse and oil pumping storehouse, deposit when the accumulational height of lubricating oil in the storehouse is greater than the height of baffle, deposit the lubricating oil in the storehouse and can flow to the oil pumping storehouse from the clearance between baffle top and oil return oil storage storehouse top.

Furthermore, the partition plate is provided with an oil passing hole.

The oil passing hole is used as a communicating part of the settling bin and the oil pumping bin, the structure is simple, the height of the oil passing hole can be set by a user according to needs, and lubricating oil in the settling bin is accumulated to different heights in different time, so that the lubricating oil is guaranteed to have enough settling time.

Further, the oil passing hole is located at the one third of the high position of the partition plate.

The oilhole sets up here, guarantees that lubricating oil has sufficient settling time, makes the lubricating oil in the storehouse of deposiing in time discharge simultaneously, avoids deposiing the lubricating oil in the storehouse and piles up too much and lead to the lubricating oil of entering equipment too little, causes equipment wearing and tearing.

Further, the oil return oil storage bin is located at the bottom of the crankcase.

The oil return and storage bin is positioned at a lower position, so that lubricating oil in the engine can enter the settling bin conveniently.

Furthermore, the precipitation bin is communicated with an oil outlet of the engine, and the oil pumping bin is communicated with an oil suction port of the engine.

Set up and deposit storehouse and oil pumping storehouse and the hydraulic fluid port intercommunication that corresponds, guarantee that equipment moves smoothly, avoid the maloperation.

Further, the oil passing hole is a square hole.

The quad slit is compared with the round hole, can make the different quad slits of putting the angle as required, and when the base and the baffle base parallel arrangement of quad slit, the oilhole width of crossing at the minimum point position of quad slit equals with the width of other positions of quad slit, guarantees that the width of crossing each high position of oilhole is all enough big, does benefit to the flowing back.
