Description

The hydraulic oil filtrating equipment of hydraulic power unit

Technical field

The utility model relates to a kind of hydraulic oil filtrating equipment of hydraulic power unit, more particularly be a kind of hydraulic oil filtrating equipment that in power line construction or maintenance, is used for lead or steel strand are carried out the hydraulic power unit of crimping or reinforcement, belong to the filter technology field.

Background technique

The Chinese patent patent No. 97235618.5,97235829.3,97235830.7,200420079628.7 discloses lead hydraulic tongs, the power source technological scheme with ultrahigh-pressure hydraulic pump, ultrahigh-pressure hydraulic pump, hydraulic wire crimping connector, can both be satisfied basically conductor compression jointing or reinforcement in transmission line construction or the maintenance by these abstract technological schemes resulting specific products.But, the claimant finds, use this type of device need change hydraulic oil in the fuel tank continually, the general replacement cycle is that the about 100h of every use promptly need change oil, thereby bring the trouble of the increase and the replacing of hydraulic oil consumption, and cause user's user cost to increase, yet, if will not duty change, then can result in blockage and influence the proper functioning of pumping plant.The crux that causes above-mentioned reason is: owing to import selector valve, Press Plier, return the hydraulic oil that lacks returning fuel tank in the whole process of fuel tank and effectively filter through pressure-relief valve from hydraulic oil that the high and low pressure oil pump is pumped, that is to say that the distributor of the direct self-commutation valve of hydraulic oil enters fuel tank.

Summary of the invention

Task of the present utility model is will provide a kind of can prolong the hydraulic oil filtrating equipment of changing the hydraulic oil time and reducing the hydraulic power unit of customer using cost effectively.

Task of the present utility model is finished like this, a kind of hydraulic oil filtrating equipment of hydraulic power unit, and it comprises that is crossed a filter ruffle 1, tool filter core chamber 11 and oil outlet 12,12 cloth of oil outlet are being crossed on the wall body all around of filter ruffle 1; One filter element 3 is contained in the filter core chamber 11; One oil outlet tube 2 was fixedly arranged on the bottom of filter ruffle 1, and its upper end is stretched in the filter element 3, and its lower end was stretched over outside the filter ruffle 1; One is used to limit filter element 3 and the filter lid 4 of cap seal on the accent in the filter core chamber 11 of crossing filter ruffle 1.

Filter element 3 described in the utility model comprises a pair of filter element upper and lower cover 31,32, and wherein, the centre is formed with the lid hole 321 that a upper end that is used for the described oil outlet tube 2 of confession was passed through among the filter element lower cover 32; The filter core 33 of one hollow is configured between the filter element upper and lower cover 31,32, is formed with filter screen 331 33 of this filter cores towards an interior side; The center filter ruffle 34 of the fuel-displaced tube chamber 341 of one tool is contained in centre among the filter core 33.

Filter core 33 described in the utility model is the papery filter core.

Center described in the utility model filter ruffle 34 has magnetic.

The utility model can be configured on the fuel tank of hydraulic power unit, makes the hydraulic oil that leaks into fuel tank by selector valve earlier through entering fuel tank again after the filtration, has protected the cleaning of fluid, prolongs the drain period, reduces customer using cost.

Description of drawings

Fig. 1 is an example structure figure of the present utility model.

Fig. 2 is an application example figure on hydraulic power unit.

Embodiment

In Fig. 1, that cross filter ruffle 1 and be hollow and open topped, the die cavity of hollow is called filter core chamber 11, the wall body of crossing filter ruffle 1 is provided with according to the mat that needs quantity and plays filter core chamber 11 and extraneous identical oil outlet 12, that is to say that the fluid in the filter core chamber 11 is introduced into fuel tank 5 (see figure 2)s from oil outlet 12.In the diapire central authorities of crossing filter ruffle 1 is an oil outlet tube 2, by the figure finding, the upper end of oil outlet tube 2 is stretched in the filter core chamber 11, the lower end then was stretched over outside the filter ruffle 1, be used for being connected with an end of oil pipe 21, the other end of oil pipe 21 then is connected on the return opening joint 61 of the distributor 6 that is arranged on selector valve (specifically asking for an interview Fig. 2).The open topped position expansion of crossing filter ruffle 1 has been set as a flange edge 13, and the whole filter ruffle 1 of crossing is located on the case lid 51 of fuel tank 5.Material is one for filter core made of paper 33 with filter element upper and lower cover 31,32 structures as far as possible, and filter screen 331 is compounded in the inwall of filter core 33, and fluid can only be earlier outside filter screen 331 leaches filter core 33.Center filter ruffle 34 with magnetic function is located in 321 places, lid hole of filter element lower cover 32.Like this, after whole filter element 3 was housed in the filter core chamber 11, the upper end of oil outlet tube 2 was stretched in the fuel-displaced tube chamber 341 of center filter ruffle 34 just.Filter cover 4 by means of screw threads and the screw 511 to the case lid 51, and cover the 4 open topped formations that will cross filter ruffle 1 by filter and seal, and filter element 3 is spacing, thus constituted a complete hydraulic oil filtrating equipment.

In Fig. 2, provided vertical hydraulic power unit, the utility model is installed on the case lid 51 of fuel tank 5, by oil pipe 21 the utility model is communicated with the distributor 6 of selector valve, specifically be that a end with oil pipe 21 is attached on the outer position of oil outlet tube 2 filter ruffle that was stretched over 1, promptly continue in the lower end of oil outlet tube 2, the other end of oil pipe 21 is continued on the return opening joint 61 of distributor 6.When hydraulic power unit in running order, the fluid of going into for 6 times in the fuel tank 5 from distributor just draws and oil outlet tube 2 by oil pipe 21, enter into the fuel-displaced tube chamber 341 of center filter ruffle 34, and then ground leaches from center filter ruffle 34, enter into the zone between center filter ruffle 34 and the filter core 33, and then seeing through filter core 33 through filter screen 331, the fluid that is leached by filter core 33 then enters fuel tank 5 from oil outlet 12.Because center filter screen 34 has magnetic, therefore, in whole filter process, the metal particle in the fluid (bits) can be adsorbed by center filter screen 34.Adopt the utility model the oil changing interval in the prior art can be extended to 400-600h from 100h.

In addition, also be very easily to the replacing of filter element of the present utility model, as long as pine is opened screw, move apart filter and cover 4 and get final product.
