Background
The load of the mining heavy truck is between 154 and 291t, and the steering action of the truck is realized by two pressure cylinders connected with front wheels. When the truck steers, the small transmission shaft of the engine rotates to drive the hydraulic pump to generate hydraulic energy, and after the hydraulic elements control the direction and pressure of liquid flow, the hydraulic energy acts on the double hydraulic cylinders of the front wheels to realize the change of the angle of the front wheels, thereby realizing the steering action. The energy accumulator equipped in the truck steering hydraulic system is used as an important auxiliary element of the truck, and has three functions: firstly, a large amount of pressure oil is provided in a short time; secondly, the system pressure is maintained for a short time when the hydraulic system loses pressure, and energy required by steering or braking is provided in an emergency; and thirdly, the hydraulic impact or pressure pulsation is reduced when the truck normally runs. At present, the truck is provided with an air bag type energy accumulator, and the structure of the air bag type energy accumulator mainly comprises an inflation valve, a shell, a capsule, an oil inlet valve and the like.
The main damage mode of the air bag type energy accumulator in the use process is aging caused by high temperature and high pressure, and once particles are externally added, the air bag is more easily damaged. However, at present, the energy accumulator is directly connected with the hydraulic system, and rubber particles formed after the rubber air bag is damaged are easy to be mixed with hydraulic oil to pollute the oil liquid, so that the pollution of the hydraulic system is caused. Rubber particles can easily and directly enter a hydraulic oil system to cause valve clamping stagnation, and hydraulic oil becomes high in quality, so that the problems of high oil temperature, failure of the hydraulic system and the like can be caused.
Disclosure of Invention
For solving between present energy storage ware and the hydraulic system lug connection cause hydraulic system easily and pollute and lead to the malfunctioning technical problem of hydraulic system action easily, the utility model provides an energy storage ware filter equipment.
In order to solve the technical problem, the utility model discloses a technical scheme is:
an accumulator filter apparatus comprising a high pressure filter cartridge assembly, a one-way outflow valve, a one-way inflow valve and a stop valve, wherein: the inlet and the energy storage ware of high pressure filter core assembly are connected, and the liquid outlet and the inlet of one-way outflow valve of high pressure filter core assembly are connected, and the liquid outlet and the hydraulic system of one-way outflow valve are connected, and the inlet and the hydraulic system of one-way inflow valve are connected, and the liquid outlet and the energy storage ware of one-way inflow valve are connected, and the stop valve is parallelly connected with one-way inflow valve.

Fig. 1 is a schematic view of the structure of the present invention.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples.
As shown in fig. 1, the accumulator filter device in the present embodiment includes a high-pressure filter element assembly 1, a one-way outflow valve 2, a one-way inflow valve 3, and a shutoff valve 4, wherein: the inlet and the energy storage ware 6 of high pressure filter core assembly 1 are connected, and the liquid outlet and the inlet of one-way outflow valve 2 of high pressure filter core assembly 1 are connected, and the liquid outlet and the hydraulic system 5 of one-way outflow valve 2 are connected, and the inlet and the hydraulic system 5 of one-way inflow valve 3 are connected, and the liquid outlet and the energy storage ware 6 of one-way inflow valve 3 are connected, and stop valve 4 is parallelly connected with one-way inflow valve 3.
Wherein, the energy accumulator 6 is a piston type energy accumulator or a gas bag type energy accumulator. The high-pressure filter element assembly 1 can filter out rubber particles generated by an air bag in the air bag type energy accumulator or metal chips generated by a piston type energy accumulator.
Optionally, a pressure difference alarm device is installed in the high-pressure filter element assembly 1. When the liquid flow pressure difference between the initial end and the tail end of the high-pressure filter element assembly 1 is larger than 0.3Mpa, the pressure difference alarm device gives an alarm and reminds the condition of the filter element in the high-pressure filter element assembly 1.
The utility model discloses in, high pressure filter core assembly 1 has the directionality in the use, and one-way outflow valve 2 prevents reverse hydraulic shock from to strain the damage that the filter core in the high pressure filter core assembly 1 caused in can preventing hydraulic oil inflow energy storage ware 6. The one-way inflow valve 3 enables the hydraulic oil discharged by the energy accumulator 6 to enter the hydraulic system 5 only after being filtered by the high-pressure filter element assembly 1, and the filtering effect on the hydraulic oil is achieved. When the pipeline is disassembled, the relief effect can be achieved by opening the stop valve 4.
When the energy accumulator 6 is filled with liquid, the hydraulic system 5 provides hydraulic oil, the upper oil way is blocked due to the action of the one-way outflow valve 2 in the upper oil way, the oil can only enter the energy accumulator 6 from the lower oil way through the one-way inflow valve 3, and the energy accumulator 6 is filled with liquid and stores energy; when the energy accumulator 6 discharges liquid, due to the flow choking effect of the unidirectional inflow valve 3 in the oil path at the lower end, the oil can only pass through the oil path at the upper end, the hydraulic oil discharged by the energy accumulator 6 is firstly filtered by the high-pressure filter element assembly 1, and the filtered pure hydraulic oil enters the hydraulic system 5 through the unidirectional outflow valve 2, so that the liquid discharge and energy release of the energy accumulator 6 are realized. To sum up, the utility model discloses an use of one-way high pressure filter core assembly 1 under two-way liquid stream environment. When the hydraulic components in the system need to be disassembled, the system pressure is released by manually adjusting the stop valve 4 so as to protect the operation safety.
