Description
Technical field
The utility model relates to mining machinery field more particularly to a kind of mine vehicles of filter core free of replacement.
Background technique
Oil filter, also known as engine oil grid.For removing the dust in machine oil, metallic particles, carbon precipitates and coal smoke
The impurity such as grain protect engine.
In engine working process, the carbon distribution and gelatinous precipitate that are oxidized under metal filings, dust, high temperature, water etc. are no
It is disconnected to be mixed into lubricating oil.The effect of oil filter is exactly to filter these mechanical admixtures and colloid, keeps the cleaning of lubricating oil, is extended
Its service life.Oil filter should have filtering ability strong, and circulating resistance is small, the performances such as long service life.
Oil filter on the market, there are two big disadvantages, and new product compensates for disadvantage, and it is therefore necessary to use new production
The strong magnetomechanical oil rectifier of product.Disadvantage one: can only filter out in machine oil 60% impurity, and filtering efficiency is low;This is because existing oil strainer
Clear device is to intercept to filter out objectionable impurities in machine oil by single paper filter element hole, and the smaller filter effect of the micropore of filter paper is just
It is better, but machine oil handling capacity is poorer.In order to solve the impurity that smallest particles can be filtered out on same filter paper micropore and
Thus making the machine oil of supply engine sufficient amount also can pass through this contradiction by micropore.Through national ic engine industry association filter point
Meeting is shown using the test of oil filter filtering efficiency ISO4548 international standard test method: even best machine in the market
Oil rectifier can only also be designed into the ability for filtering out 60% impurity in machine oil, this is the most serious offense obtained after thousands of times are tested
Filter value.In actual use, it there are also 40% objectionable impurities, cannot be effectively filtered out by paper filter element, in this 40% impurity, due to iron
Magnetic impurity is relatively tiny and hard, so in the majority with Ferromagnetic Impurities, it is also just maximum to engine damage.Disadvantage two:
Filtering efficiency is zero under specific condition;The existing oil filter used is designed with by-passing valve in the bottom of paper filter element, this be
When design, in order to be cold-started that engine oil viscosity is big or paper filter element is by Partial Blocking or when all blocking in view of engine, guarantee
Machine oil energy smooth circulation postbacks motivation and the direct oil flow channel that designs.When machine oil opens by-passing valve under the pressure of oil pump,
The machine oil for being recycled back to engine through by-passing valve at this time not only cannot get the filtering of paper filter element, but also can be by original by paper filter element
The large granular impurity filtered out brings continual secondary abrasion to engine through by-passing valve again refunds into engine,
Therefore the oil filter used on the market, plays a role in filtering under specific condition, at all so filtering efficiency at this time is
Zero.
And for heavy-duty machineries such as mining machineries, the carbon of engine clast and the machine oil generation generated during the work time
Particle and various reaction products can be more than common mechanical, therefore the requirement to oil filter is just higher, and the existing stage needs
Filter core is frequently replaced, to prevent filter net jam or the run-down damage caused to body, but this mode is at high cost
It is time-consuming and laborious.The free of replacement of filter core is realized so if can improve to the structure of filter core, is bound to that a large amount of manpowers can be saved
Material resources save cost.
