Abstract
A front oil replenishing device of hydraulic stations comprises a plurality of oil injection valves of in-station oil tanks of the hydraulic stations. The front oil replenishing device is characterized in that a replenished oil injection valve on an oil injection port of a replenished oil tank of the front oil replenishing device is communicated with an oil source pipe, the replenished oil tank is communicated with a replenished oil pump by a stop valve, the replenished oil pump is communicated with a primary high-pressure oil outlet filter, the primary high-pressure oil outlet filter is communicated with a secondary high-pressure oil outlet filter, and the secondary high-pressure oil outlet filter is respectively communicated with a replenished oil outlet valve and an internal circulating valve via a tee joint; the replenished oil tank is communicated with an oil return filter, and the oil return filter is respectively communicated with a replenished oil return valve and another port of the internal circulating valve via a tee joint by the aid of pipelines; and the replenished oil outlet valve is respectively communicated with the oil injection valves of the in-station oil tanks of the hydraulic stations, an oil inlet end of the oil injection valve of the in-station oil tank of each hydraulic station is communicated with an out-station oil return valve, and each out-station oil return valve is communicated with the replenished oil return valve. The front oil replenishing device has the advantages that oil is internally and circularly filtered before being replenished to the various hydraulic stations, and accordingly replenished oil is high in cleanliness.
Description
Technical field:
The utility model relates to hydraulic structure, particularly the preposition recharging oil device of liquid petrol station.
Background technique:
There are a plurality of hydraulic equipments in our company, and its power is supplied with by several hydraulic stations, and each hydraulic station all arranges by fuel tank, return filter, oil pump, interior circulation valve, website oil outlet, website return opening in the station and forms.Be provided with pouring orifice, oil outlet, return opening on fuel tank in standing, be provided with the website fuel feeding valve on pouring orifice and be used for replenishing hydraulic oil, stand interior fuel tank oil outlet successively with oil pump, website outlet valve, hydraulic equipment pipeline connection.The hydraulic equipment oil outlet successively with the website return filter, stand in tank drainback mouth pipeline connection, also be connected in series an interior circulation valve on connecting pipeline between oil pump oil drain out and website return filter filler opening, not externally during fuel feeding, in stand, fuel tank is by oil pump, interior circulation valve, return filter enforcement internal circulation filtering at hydraulic station.
Cleanliness of hydraulic oil is the essential condition that guarantees the normal operation of hydraulic system.Conventional hydraulic system oil liquid turbidity test should be not less than 9 grades (NAS1638 standards, lower same).The hydraulic system that control accuracy is high is higher for the requirement of oil cleanliness: the hydraulic system of proportional valve, oil cleanliness should be not less than 7 grades usually.The servo hydraulic system oil cleanliness should be not less than 6 grades.And the turbidity test of hydraulic oil when dispatching from the factory are generally 10 grades of left and right.Occur to leak or change oil when needing to replenish hydraulic oil when hydraulic system, by the common direct injection liquid pressing system of oil-filling device, will inevitably cause system's oil cleanliness to reduce in new hydraulic oil, thereby affect the normal operation of hydraulic system.
Metallurgical equipment is the caster hydraulic system particularly, and is in large scale, and user's point is many, and hydraulic fluid leak is difficult to avoid.When a large amount of oil liquid leakage appears in hydraulic system, tend to cause disorderly closedown, even lead to serious accident.
Summary of the invention:
The purpose of this utility model is to overcome defects, and a kind of preposition recharging oil device of hydraulic station is provided.
the utility model scheme is: comprise tank filling valve in some hydraulic stations stations, it is characterized in that: preposition recharging oil device is by the repairing fuel tank, the repairing oil pump, two high pressure go out oil strainer, a return filter, interior circulation valve, the repairing outlet valve, the repairing scavenger valve forms, repairing fuel feeding valve on the repairing oil filling orifice of fuel tank and oil sources pipe pipeline connection, the oil outlet of repairing fuel tank is by stop valve and repairing oil pump filler opening pipeline connection, repairing oil pump oil outlet and one-level high pressure go out oil strainer filler opening pipeline connection, the one-level high pressure goes out the oil strainer oil outlet and the secondary high pressure goes out oil strainer filler opening pipeline connection, the secondary high pressure go out the oil strainer oil outlet by threeway respectively with the repairing outlet valve, interior circulation valve pipeline connection, repairing tank drainback mouth and return filter oil outlet pipeline connection, the return filter filler opening by threeway respectively with repairing scavenger valve, interior circulation valve another port pipeline connection, the repairing outlet valve respectively with the station of some hydraulic stations in tank filling valve pipeline connection, scavenger valve pipeline connection outside tank filling valve oil inlet end and station in the station of each hydraulic station, each outer scavenger valve in station respectively with repairing scavenger valve pipeline connection.
The utility model has the advantage of: preposition recharging oil device is oily internal circulation filtering in advance, replenishes then for each liquid petrol station and refuels, and makes repairing reach high cleanliness, has guaranteed that hydraulic equipment normally moves.
Description of drawings:
Accompanying drawing 1 is the utility model structural representation.
Embodiment:
the utility model structure comprises tank filling valve 8 in some hydraulic stations stations, it is characterized in that: preposition recharging oil device is by repairing fuel tank 1, repairing oil pump 2, two high pressure go out oil strainer 3, a return filter 4, interior circulation valve 5, repairing outlet valve 7, repairing scavenger valve 6 forms, repairing fuel feeding valve 11 and oil sources pipe pipeline connection on repairing fuel tank 1 pouring orifice, the oil outlet of repairing fuel tank 1 is by stop valve and repairing oil pump 2 filler opening pipeline connections, repairing oil pump 2 oil outlets and one-level high pressure go out oil strainer 31 filler opening pipeline connections, the one-level high pressure goes out oil strainer 31 oil outlets and the secondary high pressure goes out oil strainer 32 filler opening pipeline connections, the secondary high pressure go out oil strainer 32 oil outlets by threeway respectively with repairing outlet valve 7, interior circulation valve 5 pipeline connections, repairing fuel tank 1 return opening and return filter 4 oil outlet pipeline connections, return filter 4 filler openings by threeway respectively with repairing scavenger valve 6, interior circulation valve 5 another port pipeline connections, repairing outlet valve 7 respectively with the station of some hydraulic stations 10 in tank filling valve 8 pipeline connections, scavenger valve 9 pipeline connections outside tank filling valve 8 oil inlet ends and station in the station of each hydraulic station, each outer scavenger valve 9 in station respectively with repairing scavenger valve 6 pipeline connections.
When not externally during fuel feeding, this device carries out internal circulation filtering by interior circulation valve 5, and when repairing outlet valve 7, when repairing scavenger valve 6 is all opened, this device also can be by the outer scavenger valve 9 enforcement outer circulations filtrations in station.
