Description
Technical field
The present invention relates to a kind of oil changing device, relate in particular to a kind of wind energy field that is applied in, being used in column foot is the wind-driven generator group wheel box hydraulic pressure oil changing device of replaceable blower fan gear box lubricating oil.
Background technique
The more oil change procedural mode of conventional wind power generator group gear type is: manual work need more be got lubricant oil in return and will be transported to engine room inside through the lift that the tower tube is equipped with; Discharge through the mode of the manual work waste lubricating oil that original gear is inner again; Transport waste lubricating oil back column foot through lift at last, the unified processing.The shortcoming of conventional art is following: heavy lifting new oil or landing waste lubricating oil make working strength of workers big; Only rely on the gravity of lubricant oil to discharge; Process is time-consuming longer, waste of manpower, whole changing oil process need 6-8 hour; When discharging waste lubricating oil and injecting new oil, discharge and injection process can cause lubricant oil to splash down or spray.Cause the cost of whole maintenance maintenance process to strengthen.
Summary of the invention
For solving the problems of the technologies described above the present invention a kind of wind-driven generator group wheel box hydraulic pressure oil changing device is provided, purpose is convenient for changing the lubricant oil in the gear-box, reduces labor strength, shortens oil changing interval, reduces maintenance cost.
Comprise gear-box and fuel tank for reaching above-mentioned purpose wind-driven generator group wheel box hydraulic pressure of the present invention oil changing device; Gear pump is communicated with fuel tank through pipeline; Gear pump passes through motor driving; Gear pump is connected with smart oil purifier through pipeline, and smart oil purifier is connected with the oil drain out of gear-box through pipeline, on the pipeline between gear pump and the smart oil purifier, is provided with hand-operated direction valve; On the pipeline between hand-operated direction valve and the smart oil purifier, be provided with first branch line, the end of first branch line is provided with relief valve.
Pipeline between described hand-operated direction valve and the smart oil purifier is provided with second branch line, and the end of second branch line is provided with the damping pressure table.
Described second branch line is provided with valve.
Pipeline between described gear pump and the fuel tank is provided with the oil suction magnetic oil filter.
Described fuel tank is located on the ground.
Advantageous effect of the present invention: solved the defective that maintenance maintenance caused, and improved efficient, the reliability of maintenance maintenance process, reduced the cost of the operating maintenance maintenance of wind power generating set simultaneously.
After the present invention being placed the column foot appropriate location of wind power generating set, only need the lift of pipeline through the tower tube be sent to gear-box place, cabin, pipeline directly be connected on the oil drain out of gear-box, then pipeline connects and finishes.Through gear pump waste lubricating oil is got back to dirty oil tank from the gear-box suction, after waste oil has been arranged, again fresh oil is injected in the gear-box through gear pump.The present invention increases oil filter at injection loop, the fresh oil that injects is carried out the essence filter, thereby more can guarantee the lubricating oil product quality, finally reaches to prolong the gear-box purpose in working life.Reduce lubricant oil injection and leakage that traditional Placement causes, thus the protection surrounding environment.

Fig. 1 is a fundamental diagram of the present invention.
Among the figure: 1, gear pump; 2, oil suction magnetic oil filter; 3, motor; 4, damping pressure table; 5, relief valve; 6: smart oil purifier; 7, pipeline; 8, gear-box; 9, fuel tank; 10, hand-operated direction valve; 11, valve; 12, first branch line; 13, second branch line.
Embodiment
Below in conjunction with accompanying drawing the present invention is described further.
Wind-driven generator group wheel box hydraulic pressure oil changing device of the present invention as shown in the figure; Comprise gear-box 8 and fuel tank 9; Gear pump 1 is communicated with fuel tank 9 through pipeline 7, and gear pump 1 drives through motor 3, and gear pump 1 is connected with smart oil purifier 6 through pipeline 7; Smart oil purifier 6 is connected with the oil drain out of gear-box 8 through pipeline 7; On the pipeline 7 between gear pump 1 and the smart oil purifier 6, be provided with hand-operated direction valve 10, the end that on the pipeline 7 between hand-operated direction valve 10 and the smart oil purifier 6, is provided with first branch line, 12, the first branch lines 12 is provided with relief valve 5; The end that pipeline 7 between hand-operated direction valve and the smart oil purifier 6 is provided with second branch line, 13, the second branch lines 13 is provided with damping pressure table 4, and second branch line 13 is provided with valve 11.
Fuel tank 9 is located on the ground, and fuel tank comprises dirty oil tank and new oil case.
Pipeline of the present invention is with after the gear-box oil drain out links to each other, and oil extraction and oiling detailed process are following:
Discharge the process of waste oil: cross the Cheng Qian at discharge waste oil, gear pump is set to the method for operation of reversing, and opens the connection valve of oil circuit, and then the inner waste lubricating oil of gear-box is drained in the dirty oil tank of column foot bottom through the mode of inhaling at the gear pump pump.Lubricant oil is under the effect of self gravitation and pump suction in the fuel tank, and the speed of oil extraction can reach 60 liters/minute, makes that the oil extraction process is simple, convenient and rapid, does not need for a long time.
Inject the process of fresh oil: behind emptying gear-box waste lubricating oil, the connection valve of blinding off a line is inserted the suction pipe of gear pump in the new oil case, and gear pump is set to positive revolving die formula, opens the connection valve of pipeline, injects the process of new oil.The speed injection rate of oiling can reach 60 liters/minute, makes it possible to accomplish very soon gear-box oiling process, make the employee simple to operation quick in the whole process of changing oil of completion gear-box.
