Abstract
The utility model discloses a novel electro-hydraulic hammer oil feeding tank which comprises an oil tank and a main engine oil pump, wherein an oil inlet pipe and an oil outlet pipe are arranged at one end of the oil tank, the main engine oil pump is connected with the oil tank through a main pump oil suction pipe, the main engine oil pump is connected with the oil inlet pipe through a magnet valve, and a cooling device and an oil suction pump are arranged in the oil tank. According to the novel electro-hydraulic hammer oil feeding tank, oil inlet quantity of every main pump is kept mutually independent and not interfered, and therefore oil supply capacity of the main pumps is uniform, and the service life of the magnet valve is prevented from being shortened resulting from unbalanced oil supply.
Description
Technical field
The utility model relates to field of machining, particularly relates to a kind of Novel electric liquid hammer oil feeding reservoirs.
Background technique
When the main lubricating oil pump of existing electric liquid hammer is worked, by the main pump fuel sucking pipe hydraulic oil in the fuel tank oil pipe is sucked, by solenoid valve input oil inlet pipe, supply with electric liquid hammer oil-feed again.
Existing electric liquid hammer needs 5 main lubricating oil pump work usually, every main lubricating oil pump is independently, but when oil-feed all and be connected on the fuel tank oil pipe, and its flow of the hydraulic oil in the fuel tank oil pipe and the flow direction are constant, this is for each main pump fuel sucking pipe in parallel in order, just arranged dividing of upstream and downstream, and the oil mass that the 1# main pump sucks is maximum, and the oil mass that the 5# main pump sucks is minimum.Cause the difference of each main pump supply capability, the work of each main pump that influences each other, the life-span of having reduced each solenoid valve.And oil absorption is fewer, and oil temperature rises faster, and the complete machine working oil temperature raises faster, and line seal is poorer.
The model utility content
The technical problem that the utility model mainly solves provides a kind of Novel electric liquid hammer oil feeding reservoirs, can guarantee that each oil inlet quantity of all main pumps is separate not interfere, thereby the supply capability that reaches main pump is consistent, reduces because fuel feeding is unbalanced and causes the solenoid valve life-span to reduce.
For solving the problems of the technologies described above, the technological scheme that the utility model adopts is: a kind of Novel electric liquid hammer oil feeding reservoirs is provided, comprise fuel tank and main lubricating oil pump, described fuel tank one end is installed into oil pipe and oil outlet tube, described main lubricating oil pump is connected with described fuel tank by the main pump fuel sucking pipe, described main lubricating oil pump is connected with described oil inlet pipe by solenoid valve, and cooler and oil scavenge pump are set in the described fuel tank.
In preferred embodiment of the utility model, described fuel tank sets out oilhole equably over against the position of main lubricating oil pump, described oil outlet bore is consistent with described main pump fuel sucking pipe, described oil outlet is welded to connect flange and seal ring, between described main lubricating oil pump and described fuel tank spacing is arranged, described main pump fuel sucking pipe length equates that with described gap length described fuel sucking pipe is connected on the described adpting flange.
The beneficial effect of the disclosed Novel electric liquid hammer of the utility model oil feeding reservoirs is: the transformation of oil pipe Placement is simple, and is easy to operate; The main pump fuel sucking pipe is with after fuel tank directly is connected, and five main pump work are independent not to affect used aloned, the solenoid valve life, and oil temperature is normal.
Description of drawings
Fig. 1 is the structural representation of the utility model Novel electric liquid hammer oil feeding reservoirs one preferred embodiment;
Fig. 2 is the enlarged diagram of A part in one preferred embodiment of the utility model Novel electric liquid hammer oil feeding reservoirs;
Each marking explanation in the accompanying drawing:
The 1-fuel tank, 2--main lubricating oil pump, 10--adpting flange, 11--oil inlet pipe, 12--return tube, 13--cooler, 14--oil scavenge pump, 21--main pump fuel sucking pipe, 22--solenoid valve.
Embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present utility model is described in detail, thereby so that advantage of the present utility model and feature can be easier to be it will be appreciated by those skilled in the art that protection domain of the present utility model is made more explicit defining.
See also Fig. 1 and Fig. 2, a kind of Novel electric liquid hammer oil feeding reservoirs comprises fuel tank 1 and main lubricating oil pump 2.
Be different from prior art, remove the fuel tank oil pipe on the prior art basis, leave equably oilhole at fuel tank 1 with the side-lower position, the oil outlet bore is consistent with the diameter of main pump fuel sucking pipe 21, mixes adpting flange 10, and each main pump fuel sucking pipe 21 is received on the adpting flange 10, main pump fuel sucking pipe 21 just directly has been connected with fuel tank 1 like this, guarantee that each main pump fuel sucking pipe 21 fuel feeding is separate, equalization of pressure, fuel delivery is impartial.
The above only is embodiment of the present utility model; be not so limit claim of the present utility model; every equivalent structure or equivalent flow process conversion that utilizes the utility model specification and accompanying drawing content to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present utility model.
