Abstract

The utility model relates to a washer for hydraulic apparatus, which is suitable for the washing of hydraulic equipment, pipelines and elements. The utility model is composed of a driving machine (4), an oil pump (3), a pressure regulating device (6), oil filters (10), (11), a sample connection (9) and an oil tank (14). Because of smooth or obtuse transition at the conical bottom of the oil tank of the utility model or in the corner of the inner wall of the oil tank, the oil tank is difficult to scale. Because of the lesser volume and the diffusion tube (15) of the utility model, oil is fully stirred in the oil tank, is fully circulated in the system and is fully filtered, and the purification efficiency is very high. The sample connection in the front of the oil filter makes the oil sampling very convenient, and the cleaning degree of the oil is authentically reflected.

Description

Washer for hydraulic apparatus

The utility model relates to a kind of hydraulic equipment relief developing machine, is the equipment that is specifically designed to purified solution pressing system, equipment, element and oil, so that improve the functional reliability of hydraulic equipment.

The known equipment that is used for filter oil has three classes at present:

(1) oil filter: domestic use is more general, and its working principle is by the oil pump on the oil filter oil that needs filter to be sucked, and is sent into behind oil purifier with the oil place by the oil pump outlet again, and the oil that is filtered is once to filter, its poor filtration effect.

(2) the clean motor of static: by the principle absorption impurity of Electrostatic Absorption, but its flow is less, can not be used for flushing.

(3) relief developing machine: flow through pipeline with clean innage speed, take away impurity, reach the purpose of flushing.Present domestic this product that still do not have, external product is (to comprise internal-combustion engine by driving machine, motor etc.), oil pump, regulator, fuel tank, compositions such as oil purifier, during use, the relief developing machine outlet is connected with needing the flushing device hydraulic fluid port, the equipment oil outlet is connected with the relief developing machine return opening, dragging oil pump by driving machine rotates, oil squeezed into from the relief developing machine inner tank to be needed towards equipment, be back to fuel tank by return opening again and form closed-circuit and filter repeatedly, because of its volume of fuel tank big, and the easy incrustation of Oiltank structure, cause the oil in the fuel tank fully not participate in filtering, influence filter efficiency, thereby influence developing result.

The purpose of this utility model provides a kind of filter efficiency height, and uses easy to operate hydraulic equipment relief developing machine.

For reaching this purpose, the technical solution that the utility model is taked is, the bottom that makes fuel tank is taper, inlet port is at lowermost end, fuel tank is garden shape or other shape but fuel tank internal corner is the garden slips over and cross, or the obtuse angle transition is provided with diffusing tube not form the dead angle at return opening, and the volume that makes fuel tank is less than 2 times of rated flow.Incorporate the external suction inlet of a bypass between oil pump and fuel tank, incorporating an export abroad into between the return opening diffusing tube behind the oil purifier, at the oil purifier front end sample tap is set, oil purifier adopts special-purpose oil purifier.

The diffusing tube that above-mentioned return opening is provided with promptly the pipe end shutoff of return tube in the fuel tank, and is opened several at tube wall and pipe end and is made the return pressure loss little but flow into the oil stream aperture that the oil of fuel tank is enough to make the oil in the fuel tank fully to roll and stir.

Above-mentioned special-purpose oil purifier is be to adapt to the utility model washing and filtering often to need the more characteristics of renew cartridge, makes the filter core mount inlet be arranged on the bottom of oil purifier down, and the end cap of renew cartridge more is set on the top of oil purifier.

Because having adopted garden shape fuel tank or other shape fuel tank internal corner employing garden in the above-mentioned solution slides or the obtuse angle transition, make no dead angle in the fuel tank, adopted at the bottom of the taper case, inlet port is arranged on lowermost end, make the incrustation phenomenon does not almost completely take place, diffusing tube is set and uses little volume fuel tank, make the stirring of can rolling fully effectively under in working order of oil in the fuel tank, thereby the chance that the oil participation is filtered is more, has improved filter efficiency thus.

In addition, at the oil purifier front end sample tap is set and makes that to take to detect oil sample very convenient and can reflect truly before oil purifier because of it by by the turbidity test of the oil that flows out in equipment.With the mount inlet of filter core down, on the top of oil purifier the more end cap of renew cartridge is set, improved conventional oil purifier and more need move the bigger whole housing of weight during renew cartridge, and the mounting point is also more easy to operate up, therefore improve operating conditions, reduced labor intensity.The external suction inlet and the outlet of being set up make work more convenient.

Below in conjunction with drawings and Examples the utility model is done further explanation:

Fig. 1 is a hydraulic schematic diagram of the present utility model

Fig. 2 is an Oiltank structure shape schematic representation of the present utility model

Fig. 3 is the structural representation of the utility model diffusing tube

Fig. 4 is the special-purpose oil filter structure schematic diagram of the utility model

(2) are the inlet port stop valve among the figure, when need when fuel tank (14) is oil-filled in machine.Need oil suction from oil drum or other oil vessel, stop valve (2) is opened, stop valve (1) is closed, start driving machine (4), oil pump (3) is driven running from the inlet port oil suction, at stop valve, (5), (8), under the situation of (12) closing, through relief valve (6), oil purifier (10), (11), the stop valve of opening (13), diffusing tube (15) pours in the fuel tank (14), after fuel tank is full of oil, open valve (1) cut-off valve (2), fluid is at the utility model internal circulation filtering, pollutant is tackled by the oil purifier filter material when oil purifier, and the oil that returns fuel tank is cleansing oil.After the filter of the oil in the fuel tank is clean, can or fill and add hydraulic equipment in order to flushing pipe.When flushing, with be rinsed the inlet/outlet of pipeline or equipment and of the present utility modelly go out, return opening connects, open stop valve (5), (8), clean oil with certain flow rate promptly enters pipeline or equipment, the sump oil that returns after the flushing is oil sump tank after filter oil purifier (10), (11), circulation reaches the purpose of flushing and purification fluid repeatedly, stop valve (9) is used for sampling, open when needing sampling, otherwise close all the time, stop valve (12) usefulness when being rapid refueling, less demanding when the turbidity test of oil, and use this outlet when needing rapid refueling.Stop valve (7) is used to protect oil purifier (10), (11).

Inlet port among Fig. 2 (17) must be arranged on the lowermost end of fuel tank.

Diffusing tube shown in Figure 3 is the least significant end of return tube (16), is made up of the pipe that one section tube wall is opened some apertures.

Figure 4 shows that oil purifier, its mounting cover up.
