Abstract
The utility model relates to a siphon self sealing high level oil tank which belongs to a high level oil tank. An upper corner in the oil tank is provided with an oil return chamber where an oil return pipe is inserted in, and the inner of the oil return chamber is provided with an oil return filter. The inner of the oil tank is provided with a housing plate of which the lower part is connected with an oil absorbing filter, and the housing plate and the oil absorbing filter together form an oil absorbing cavity; the oil absorbing pipe is inserted into the oil absorbing cavity, and the pipe orifices of the oil return pipe and the oil absorbing pipe are higher than the highest oil level; a screw plug is arranged below the housing plate. The utility model has the advantages of simple structure, sufficient exertion of the oil tank, no outflow oil during the maintenance of the oil tank and resources saving, and the utility model completely realizes no pollution to environment and puts an end to the occurrence of system serious accidents for the reason that a valve is forgotten to open.
Description
The utility model relates to a kind of high fuel tank of putting, and the siphon self-sealing height in particularly a kind of hydraulic efficiency pressure system is put fuel tank.
At present, most of construction machinery and equipment is that the fuel tank on the loader all adopts height to put, and the fuel tank height is put the oil suction position height of the installation site of fuel tank soon than pump, and oil suction and return opening are arranged at the bottom of fuel tank, and oil filling port is arranged at fuel tank top, and oil suction is connected with oil pump.Height is put the oil suction resistance that fuel tank can reduce oil pump, prolongs the service life of oil pump, but very inconvenient during the maintenance fluid pressing system, does not add any protective device on the oil suction pipe, when pulling down oil pump, and the oil contaminated environment that just outflows, waste resource; On oil suction pipe, install the self-sealing fil additional, increased the oil suction resistance, when safeguarding pretty troublesome; On oil suction pipe, install switch valve additional, increased security of system hidden danger, forget after the maintenance and open valve, cause the grave accident of system easily.
The purpose of this utility model is to provide that a kind of oil does not outflow when pulling down oil pump, easy to maintenance, safe siphon self-sealing height puts fuel tank.
The purpose of this utility model is achieved in that in fuel tank one angle oil-in chamber once, oil return pipe is inserted in the oil back chamber, one cover plate is arranged in fuel tank, the cover plate bottom connects the oil suction fil, cover plate and oil suction fil are formed an oil sucting cavity, oil suction pipe is inserted in the oil sucting cavity, and a screw plug is arranged above cover plate.
The mouth of pipe of oil return pipe and oil suction pipe is higher than the maximum oil liquid level; The oil return fil arranged in that oil back chamber is indoor.
Owing to adopted such scheme, the mouth of pipe of oil suction pipe is higher than the maximum oil liquid level, oil suction chamber top is a cavity, when oil pump passes through the oil suction pipe oil suction, at first vacuum is aspirated in the indoor top of oil sucting cavity, form negative pressure, at this moment the oil in the fuel tank is gone into oil suction pipe by the oil suction fil with oil pressure under the effect of bar pressure.During the maintenance fluid pressing system, the screw plug of cover plate top is unscrewed, the indoor vacuum of oil sucting cavity is destroyed, oil in the oil suction pipe is emitted, because the mouth of pipe of oil suction pipe and oil return pipe all is higher than the maximum oil face, so just no longer outwards trickling of the oil in the fuel tank, the oil when pulling down oil pump in the fuel tank is not to outflow; After maintenance finishes, need not open just energy normal operation of valve, so easy to maintenance, safety has reached the purpose of this utility model.This Oiltank structure is simple, and high advantage of putting fuel tank has been given full play in manufacturing, easy to maintenance, pull down oil pump during maintenance, the oil in the fuel tank does not outflow, and has saved resource, realize environmentally safe fully, stopped to forget the generation of system's grave accident of opening valve and causing.
Be described further in conjunction with the embodiments with reference to the accompanying drawings below.
Accompanying drawing is a constructional drawing of the present utility model.
Embodiment: angle oil-in chamber 3 once in fuel tank 1, oil return pipe 2 is inserted in the oil return chamber 3, oil return fil 4 is arranged in oil return chamber 3, one cover plate 5 is arranged in fuel tank 1, cover plate 5 bottoms connect oil suction fil 8, and cover plate 5 and oil suction fil 8 are formed an oil sucting cavity, and oil suction pipe 7 is inserted in the oil sucting cavity, the mouth of pipe of oil return pipe 2 and oil suction pipe 7 is higher than the maximum oil liquid level, and a screw plug 6 is arranged above cover plate 5.
Claims (2)
1, a kind of siphon self-sealing height is put fuel tank, comprise fuel tank, oil return pipe, oil suction pipe, it is characterized in that: angle oil-in chamber once in fuel tank, oil return pipe is inserted in the oil back chamber, one cover plate is arranged in fuel tank, and the cover plate bottom connects the oil suction fil, and cover plate and oil suction fil are formed an oil sucting cavity, oil suction pipe is inserted in the oil sucting cavity, and a screw plug is arranged above cover plate.
2, siphon self-sealing height according to claim 1 is put fuel tank, and it is characterized in that: the mouth of pipe of described oil return pipe and oil suction pipe is higher than the maximum oil liquid level; The oil return fil arranged in that oil back chamber is indoor.
