Adopt rubber seal between described precompressed air filter cleaner and the hydraulic oil container.
Advantage and the good effect that the utlity model has are:
The leather bag device communicates with the external world, by the pressure in the contraction adjusting hydraulic oil container of leather bag, set up the cracking pressure of precompressed air filter cleaner, can keep the pressure in the fuel tank, when precompressed air filter cleaner and leather bag device one work, can reduce the opening times of precompressed air filter cleaner, reduce the time that hydraulic oil container communicates with ambient air, enter fuel tank thereby reduce external impurities, guarantee the turbidity test of hydraulic oil in the hydraulic oil container.
Description of drawings
Fig. 1 is the utility model structural representation;
Among Fig. 1,1. oil absorption filter, 2. return filter, 3. level meter, 4. precompressed air filter cleaner, 5. leather bag, 6. resuscitation apparatus, 7. hydraulic oil container.
Embodiment
For further understanding model utility content of the present utility model, Characteristic, hereby exemplify following examples, and cooperate accompanying drawing to be described in detail as follows:
See also Fig. 1, a kind of development machine hydraulic oil container dust guard, mainly comprise hydraulic oil container 7, oil absorption filter 1, return filter 2, precompressed air filter cleaner 4, leather bag 5 and resuscitation apparatus 6, hydraulic oil container 7 tops connect tank cover, be coated with sealant sealing with rubber pad between tank cover and the hydraulic oil container 7, oil absorption filter 1 is installed in the position on the lower, side of hydraulic oil container 7, adopts rubber seal between oil absorption filter 1 and the hydraulic oil container 7.Return filter 2 is installed on the tank cover of hydraulic oil container 7 front ends, adopts rubber seal between return filter 2 and the hydraulic oil container 7.Precompressed air filter cleaner 4 is installed on the tank cover of hydraulic oil container 7 rear ends, adopt rubber seal between precompressed air filter cleaner 4 and the hydraulic oil container 7, the below of precompressed air filter cleaner 4 is equipped with level meter 3, level meter 3 is arranged in hydraulic oil container 7, leather bag 5 is installed on the tank cover of hydraulic oil container 7, leather bag 5 bodies are in hydraulic oil container 7, and leather bag 5 adopts with tank cover and is threaded, and adopt O type circle and hydraulic oil container 7 sealings.Leather bag 5 openings are installed resuscitation apparatus 6, and resuscitation apparatus 6 adopts with leather bag 5 and is threaded, and the inner chamber of leather bag 5 is communicated with the external world.
During development machine work, hydraulic oil enters into oil hydraulic pump by oil absorption filter 1, and then enters into hydraulic pipe line, finishes the action of development machine.When hydraulic oil during by the oil hydraulic pump sucking-off, the pressure in the hydraulic oil container 7 change, and at this moment need to regulate the pressure of hydraulic oil container 7, with the oil suction constant pressure of maintenance medium press pump.Leather bag 5 communicates with the external world, by the pressure in the contraction adjusting hydraulic oil container 7 of leather bag 5, all the time the pressure of hydraulic oil container 7 is regulated.And precompressed air filter cleaner 4 sets pressure, and when the pressure of hydraulic oil container 7 reached certain critical value, precompressed air filter cleaner 4 was opened, and plays the effect of the pressure of regulating hydraulic oil container 7.Because the contraction of leather bag 5, the opening times of precompressed air filter cleaner 4 has greatly reduced, and has reduced the time that hydraulic oil container 7 communicates with ambient air, and then has reduced the probability that foreign material enter hydraulic oil container 7.Like this, under the double action of leather bag 5 and precompressed air filter cleaner 4, played good dust-proof effect.
