Abstract
The utility model discloses a slit type filter for an oil injector. The slit type filter for the oil injector comprises a cylindrical filter element, wherein two ends of the excircle of the filter element are provided with multiple grooves respectively; the multiple grooves extend along the axial direction of the filter element and further are evenly distributed in a manner of being relative to the circumference of the revolving center of the filter element; the length of each groove is more than half the length of the filter element; the multiple grooves in two ends of the filter element are arranged in a staggering way; two ends of the filter element are provided with an oil inlet blind groove respectively; each oil inlet blind hole extends along the axial direction of the filter element; the length of each oil inlet blind hole is less than half the length of the filter element; a connection hole is formed between each oil inlet blind hole and each groove; and each groove is communicated into each oil inlet blind hole through multiple connection holes. With the adoption of the slit type filter for the oil injector, under the premise of not increasing the diameter of the filter element, the circulation area of an oil inlet section can be increased; and therefore, the flow rate is increased and the throttling affection of the traditional slit type filter element is improved.
Description
Technical field
The utility model relates to a kind of filter, is specifically related to a kind of split strainer for oil sprayer.
Background technique
The existing split strainer that is applied to oil sprayer is only considered its filter capacity, when in the high-pressure oil pipe of putting into limited space or oil sprayer, the filter core diameter is restricted, and the circulation area in oil-feed cross section is less, throttling is more serious, can affect the jet power of oil sprayer.
In order to reduce throttling, must increase the diameter of filter core, cause filter core can't be directly installed in high-pressure oil pipe oil duct or oil injector body internal oil channel, this just needs other pipe box and pipe joint, be connected on high-pressure oil pipe, the increase of these component makes failure risk strengthen again.
Existing split strainer comprises cylindrical filter core, and the external diameter of filter core forms the filtration seam of ring-type less than the diameter of oil injector body internal oil channel or high-pressure oil pipe oil duct between filter core and oil duct; The cylindrical two ends of filter core are respectively arranged with many grooves, and many grooves extend axially along filter core, and with respect to the gyration center circumference uniform distribution of filter core; The length of groove is greater than half of filter core length; The groove at filter core two ends is crisscross arranged (groove that is two ends directly is not communicated with).
The split strainer of this structure is fixed owing to filtering seam, so the gap length of filter core has designing requirement.In order to make can pack into common high-pressure oil pipe oil duct or be directly installed in the oil injector body internal oil channel of filter core, the sectional area of filter core will be subject to spatial constraints, so groove circulation gross area S1 is less than cross section, gap gross area S4, as shown in Figure 1, the oil-feed actual internal area is groove circulation gross area S1.
The model utility content
Technical problem to be solved in the utility model is to provide a kind of split strainer for oil sprayer, and it can solve the more serious problem of throttling under the limited condition of installing space.
For solving the problems of the technologies described above, the technical solution that the utility model is used for the split strainer of oil sprayer is:
Comprise cylindrical filter core, the cylindrical two ends of filter core are respectively arranged with many grooves, and many grooves extend axially along filter core, and with respect to the gyration center circumference uniform distribution of filter core; The length of groove is greater than half of filter core length; Many the grooves at filter core two ends are crisscross arranged; The two ends of filter core are respectively arranged with an oil-feed blind hole, and the oil-feed blind hole extends axially along filter core, and the length of oil-feed blind hole is less than half of filter core length; Be provided with attachment hole between oil-feed blind hole and each groove; Every groove is communicated with the oil-feed blind hole by a plurality of attachment holes.
The diameter of described attachment hole is less than the diameter of oil-feed blind hole.
The cross section gross area of described a plurality of attachment holes is greater than 1/4 of the section area of oil-feed blind hole.
In described a plurality of attachment hole, be positioned at the attachment hole quantity of oil-feed blind hole bottom greater than the attachment hole quantity that is positioned at oil-feed blind hole top.
The diameter of described attachment hole is not more than 1mm.
The technique effect that the utility model can reach is:
The utility model can increase the circulation area in oil-feed cross section under the prerequisite that does not increase the filter core diameter, thereby augmented flow has improved the throttling impact of traditional clearance filter.
The utility model can be realized classified filtering, and the impurity of coarse filtration can be piled up in the bottom of oil-feed blind hole, can improve filtration reliability, is not easy to block, and lengthens working hours.
The utility model need not to increase the filter core diameter, has strengthened the applicability of filter core.

Embodiment
As extremely shown in Figure 4 in Fig. 2, the utility model is used for the split strainer of oil sprayer, comprise cylindrical filter core 1, the external diameter of filter core 1 forms the filtration seam 10 of ring-type less than internal diameter 4～6 μ m of high-pressure oil pipe (or in oil injector body) oil duct 2 between filter core 1 and high-pressure oil pipe (or in oil injector body) oil duct 2;
The cylindrical two ends of filter core 1 are respectively arranged with many grooves 11, and many grooves 11 extend axially along filter core 1, and with respect to the gyration center circumference uniform distribution of filter core 1; The length of groove 11 is greater than half of filter core 1 length; Many the grooves 11 at filter core 1 two ends are crisscross arranged (groove 11 that is two ends directly is not communicated with);
The two ends of filter core 1 are respectively arranged with an oil-feed blind hole 12, and oil-feed blind hole 12 extends axially along filter core 1, and the length of oil-feed blind hole 12 is less than half of filter core 1 length; Oil-feed blind hole 12 is arranged at the central authorities of filter core 1;
Be provided with attachment hole 13 between oil-feed blind hole 12 and each groove 11; Every groove 11 is communicated with oil-feed blind hole 12 by a plurality of attachment holes 13;
