Description
Technical Field
The utility model relates to a flushing device of a hydraulic mechanism.
Background
The hydraulic mechanism of the circuit breaker is characterized in that the cleanliness requirement of a hydraulic system is higher, the total content of internal impurities is not more than 0.05g, otherwise, the situation that impurities scratch the internal piston or sealing ring possibly occurs, oil leakage is caused, and the stable operation of the hydraulic operating mechanism and the circuit breaker is influenced.
When the hydraulic mechanism is operated after the assembly is completed, new foreign impurities may remain or be generated in the hydraulic mechanism, and certain gases remain in the hydraulic mechanism, so that the impurities and the gases need to be discharged. The action of the hydraulic mechanism is high-speed action, the flow rate of hydraulic oil in the system is high during the action, and at the moment, internal impurities and gas are easy to be discharged; after the hydraulic mechanism acts, energy storage can be carried out, an oil pump can be started, and the oil pressure is supplemented to the rated oil pressure. The hydraulic mechanism is connected with the flushing device, so that hydraulic oil can circularly flow in the hydraulic mechanism and the flushing device to form a new hydraulic system. The flushing device can continuously filter the impurity-and gas-containing hydraulic oil discharged by the hydraulic mechanism, and simultaneously, the filtered clean hydraulic oil is communicated with an oil pump of the hydraulic mechanism, and the hydraulic oil is pumped into the hydraulic mechanism. Since the flow rate of the hydraulic oil is high when the hydraulic mechanism is operated, the discharged hydraulic oil washes the inside of the hydraulic mechanism, so this process is called a flushing process, and this device is called a flushing device.
The existing flushing device is as in the chinese patent with publication number CN201294165Y, which discloses a flushing device comprising an oil tank comprising an oil return chamber (i.e. the oil supply tank in the patent) and an oil outlet chamber (i.e. the oil discharge tank in the patent), wherein the oil return chamber is separated from the oil outlet chamber by a longitudinal partition, the oil return chamber is connected with an oil drain of the hydraulic mechanism by an oil return pipe, and the oil outlet chamber is connected with an oil inlet of the hydraulic mechanism by an oil outlet pipe. The filter which is communicated with the oil return cavity and the oil outlet cavity is fixed on the longitudinal partition plate, and hydraulic oil in the oil return cavity enters the oil outlet cavity through the filter.
The flushing device of the prior art filters hydraulic oil through a filter, so that clean hydraulic oil is introduced into a hydraulic mechanism again for circular flushing, but the problem is that: when gas exists in the hydraulic system, cavitation can be generated, the operation efficiency of the oil pump can be reduced, and noise and equipment abrasion are increased. However, the flow rate of hydraulic oil discharged by the hydraulic mechanism is high, and the hydraulic oil can rapidly roll and mix a large amount of gas when entering the oil return cavity. The gas is wrapped and rushed into the oil outlet cavity through the filter; because the distance between the filter and the oil outlet of the oil outlet cavity is short, the flow speed of hydraulic oil is high, and gas can be further wrapped and clamped into the hydraulic mechanism. After the flushing is completed, gas remains in the hydraulic mechanism, which can cause damage to the hydraulic mechanism.

The present utility model is described in further detail below with reference to examples.

as shown in fig. 1 to 4, the flushing device of the hydraulic mechanism (hereinafter referred to simply as flushing device) forms a circulation loop with the hydraulic mechanism when in use, small impurities in the hydraulic mechanism are flushed out by hydraulic oil, and clean hydraulic oil is sent to the hydraulic mechanism again after filtration.
As shown in fig. 1, the flushing device generally comprises a mounting bracket 100 and an oil tank 200 detachably fixed on the mounting bracket 100, wherein the mounting bracket 100 comprises a base bracket 101 and an heightening frame 102 which are detachably connected, the oil tank 200 is detachably mounted on the heightening frame 102, the detachable connection is implemented by bolts, specifically, folded edges are fixed on the oil tank 200, the base bracket 101 and the heightening frame 102, and the folded edges are connected by bolts. The height of the oil tank 200 can be adjusted by adding or removing the height-increasing frame 102 to be adapted to hydraulic mechanisms of different heights. To facilitate the movement of the flushing device, road wheels are fixedly mounted at the bottom of the base bracket 101.
The structure of the fuel tank 200 is shown in fig. 2 to 4, and the fuel tank 200 includes a lower tank body formed of a tank bottom plate 204 and a tank side plate 213, and an upper tank cover. Two partition plates 211 which are sequentially arranged are fixedly arranged in the oil tank 200, the partition plates 211 divide the inner cavity of the oil tank 200 into an oil return cavity 208, an intermediate oil cavity 209 and an oil outlet cavity 210, and the cavities are arranged in a line. The oil tank side plate 213 is fixedly provided with an oil return port 202 and an oil outlet 201, the oil return port 202 is directly communicated with the oil return cavity 208, and the oil outlet 201 is directly communicated with the oil outlet cavity 210.
An oil return pipe 300 is fixedly arranged on the oil return port 202, the oil return pipe 300 is a hose, and the oil outlet hole and the oil return cavity 208 of the hydraulic mechanism are communicated when the hydraulic mechanism is used, so that hydraulic oil in the hydraulic mechanism flows back into the oil tank 200; an oil outlet pipe 400 is fixed on the oil outlet 201, the oil outlet pipe 400 is a hose, when in use, the oil outlet cavity 210 is communicated with an oil pump of a hydraulic mechanism, and after the hydraulic mechanism works, a motor is started and drives the oil pump to carry out pressure compensation.
The filter mounting holes 206 are formed in the partition 211, the filter mounting holes 206 are communicated with two adjacent cavities (comprising an oil return cavity 208, a middle oil cavity 209 and an oil outlet cavity 210), the filter 207 is fixedly mounted at the filter mounting holes 206, and the filter 207 filters tiny impurities in hydraulic oil so as to ensure that the hydraulic oil re-entering the hydraulic mechanism is purer. A filter 207 is also fixedly mounted on the oil outlet 201, and the filter 207 is located in the oil tank 200.
Because the hydraulic oil has a faster flow rate in the hydraulic mechanism, the hydraulic oil entering the oil return cavity 208 has a faster flow rate, more gas is mixed in the hydraulic oil, and if the gas content is not reduced, the gas enters the hydraulic mechanism again, so that the hydraulic mechanism is damaged, and the efficiency of the oil pump is reduced. For this purpose, as shown in fig. 3, an oil return bend 205 is fixedly installed at the oil return port 202, and the oil return bend 205 is located in the oil return chamber 208, and the oil return bend 205 includes a laterally extending section 2051 and a vertically extending section 2052, and it should be noted that, in this embodiment, whether it is horizontal or vertical, it does not refer to absolute horizontal or vertical, but refers to a general extending direction thereof. Of course, in this embodiment, the horizontal extension 2051 extends horizontally, the vertical extension 2052 extends vertically downward, and when hydraulic oil enters the return bend 205, the flow rate of the hydraulic oil can be reduced, and the impact force of the hydraulic oil entering the return chamber 208 is reduced.
In this embodiment, to reduce the rolling degree of the hydraulic oil in the oil return chamber 208 to reduce the mixing amount of the gas, as shown in fig. 3, the tank bottom plate 204 is disposed obliquely, specifically, the tank bottom plate 204 includes an inclined portion 2041 and a horizontal portion 2042, and a precipitation area is formed between the horizontal portion 2042 and the tank side plate 213 for precipitating the impurities. And the inclined portion 2041 corresponds to the vertical extending section 2052 from top to bottom, because the inclined portion 2041 extends obliquely, when hydraulic oil is flushed out through the vertical extending section 2052, the inclined portion 2041 can conduct integral drainage to the hydraulic oil, and the hydraulic oil is guided to flow towards one direction, so that the rolling degree of the hydraulic oil is reduced. Further, as shown in fig. 3, in order to prevent hydraulic oil from directly flowing to the intermediate oil chamber 209 through the filter 207 on the partition 211, the vertically extending sections 2052 are arranged at intervals (in the left-right direction of fig. 3) from the adjacent filter 207.
In order to further reduce the flow rate of the hydraulic oil for better filtration and oil-gas separation, in this embodiment, the filter mounting holes 206 on each partition 211 are staggered, so that the hydraulic oil can flow in a curved manner. Moreover, the filters 207 on the oil return port 202 and the adjacent filters 207 are also staggered, so that the opposite direction is prevented.
In the use process, the filtered impurities are more precipitated in a precipitation area formed by the horizontal part 2042 and the oil tank side plate 213, and for facilitating regular cleaning, an oil drain valve mounting hole 212 is formed in the horizontal part 2042 corresponding to each cavity, and an oil drain valve 203 is fixedly mounted on the oil drain valve mounting hole 212.

As shown in fig. 1, in this embodiment, the inner diameter of the oil return pipe 300 is larger than the inner diameter of the oil outlet pipe 400, so that the flushing of the hydraulic mechanism with large oil discharge can be performed, and the flow rate of the hydraulic oil entering the oil return chamber 208 can be slowed down due to the larger inner diameter of the oil return pipe 300. When the hydraulic flushing device is used, each pipeline is connected with the hydraulic mechanism, circulation of hydraulic oil is carried out, and the hydraulic mechanism is flushed in the circulation process.
In the present embodiment, the inclined portion 2041 forms a bottom plate corresponding portion corresponding to the vertically extending section. The filter mounting holes form oil passing channels communicated with the adjacent two cavities, and the filter forms a filter structure arranged at the oil passing channels.
