Please refer to Fig. 2 to Fig. 4, said drilling pump 200 comprises base 210, frame 220, fuel tank 230 and cross lap 240; Said base 210 stands on ground, and said frame 220 is installed on the said base 210, thereby said base 210 cooperates other parts that firmly support said drilling pump 200 with said frame 220; Said fuel tank 230 is arranged on the said base 210, is contained with lubricant oil in the said fuel tank 230, the cylinder sleeve piston of said drilling pump 200 is lubricated being used for, and guarantees the proper functioning of said drilling pump 200; Said cross lap 240 is removably installed on the said frame 220, overhauls with the associated components that is easy to open 240 pairs of said drilling pumps 200 of said cross lap, and is formed with containing space 201 between said cross lap 240 and the base 210.Said lubricating fitting is installed on the said drilling pump 200; And said lubricating fitting is communicated with said fuel tank 230, thus through said lubricating fitting with the lubricant oil in the said fuel tank 230 through being lubricated on the cylinder sleeve piston that is sent to said drilling pump 200 after the handled.Wherein, the specific structural features of said drilling pump 200 and each parts thereof and performance effect all are well known to those skilled in the art, and no longer are repeated in this description at this.
Particularly; Said lubricating fitting comprises coarse-grain filtering device 310, oil pump 320, fine filter 330 and cooler 340; And said coarse-grain filtering device 310, oil pump 320, fine filter 330 and cooler 330 are communicated with through pipeline 350 order successively; And make said fuel tank 230 be communicated to the cylinder sleeve piston of said drilling pump 200, thus form a complete oil circuit, with the lubricant oil that transmits in the said fuel tank 230 said cylinder sleeve piston is lubricated.Said coarse-grain filtering device 310 is installed on a side of said frame 220; And said coarse-grain filtering device 310 is communicated with said fuel tank 230 through pipeline 350; Thereby 310 pairs of lubricant oil that flow out said fuel tank 230 of said coarse-grain filtering device carry out primary filter, with the more coarse impurity that carries in the filtering lubricant oil; Said oil pump 320 is installed on a side of said base 210; The filler opening of said oil pump 320 is communicated with said coarse-grain filtering device 310 through said pipeline 350; Said stream fuel tank 230 provides power thereby said oil pump 320 is for lubricant oil flows out, to be sent to lubricant oil on the parts of required use; In the preferred implementation of the utility model; Said coarse-grain filtering device 310 and said oil pump 320 are positioned at the same side (see figure 4) of said base 210 or frame 220; Thereby can reduce to connect the pipeline 350 between said coarse-grain filtering device 310 and the oil pump 320, reduce the cost of production of whole said drilling pump 200; The two ends of said fine filter 330 are communicated with the oil outlet of said oil pump 320 and the filler opening of cooler 340 through pipeline 350 respectively; 330 pairs of lubricant oil from said oil pump 320 interior outflows of said fine filter filter once more; With the various impurity that possibly carry in the filtering lubricant oil; To guarantee the turbidity test of lubricant oil, improve lubrication effect to said drilling pump 200 cylinder sleeve pistons; Said fine filter 330 is installed in the said containing space 301; Thereby said fine filter 330 is installed in other space that need not take said drilling pump 200; And effectively utilized the free space in the said containing space 301, further reduced the volume of whole drilling pump; Said cooler 340 is installed on the said cross lap 240; Said cooler 340 is connected to said cylinder sleeve piston through pipeline 350; Thereby 340 pairs of lubricant oil after said fine filter 330 filters once more of said cooler cool off; And be sent to cooled lubricant oil on the said cylinder sleeve piston, to guarantee the temperature requirement of cylinder sleeve piston, further improve the effect that the cylinder sleeve piston is lubricated to lubricant oil; And said cooler 340 is installed on the said cross lap 240; Effectively utilized the free space on the said cross lap 240; The volume that need not increase said drilling pump 200 gets final product the said cooler 340 of normal mounting, has reduced the volume and the weight of whole said drilling pump.
As a preferred implementation of the utility model, each said pipeline 350 is steel pipe, uses steel pipe as pipeline, and its longer service life can guarantee that the long-term transmission of lubricant oil is transported; And steel pipe is arranged on the said drilling pump 200, and layout more not only makes things convenient for transportation but also makes the overall appearance of drilling pump more attractive in appearance.
The said lubricating fitting that is used for drilling pump of the utility model is respectively arranged with two coarse-grain filtering devices 310, fine filter 330 and cooler 340, and said oil pump 320 is set to one, thereby can constitute two complete oil circuits, and oil circuit and transmission oil circuit promptly reflux; Said transmission oil circuit is made up of said coarse-grain filtering device 310, oil pump 320, fine filter 330, cooler 340 and pipeline 350, the lubricant oil in the said fuel tank 230 is sent on the said cylinder sleeve piston, so that the cylinder sleeve piston is lubricated, specifically as stated; The said coarse-grain filtering device of said withdrawing oil route 310, fine filter 330, cooler 340 and pipeline 350 are formed; Lubricant oil after this oil circuit makes and lubricated is back in the said fuel tank 230; To repeat utilization, the detailed process of this oil circuit work is identical with said transmission oil circuit, and difference only is not use oil pump 320; Because the oil mass that refluxes is less relatively; So oil circuit need not use oil pump 230 can make in lubricant oil natural back flow to the said fuel tank 230, therefore, no longer specifically describes the concrete running of backflow oil circuit.
From the above, the lubricating fitting that is used for drilling pump of the utility model directly is installed on said drilling pump 200, makes when said lubricating fitting is installed; Do not need to be provided with in addition bearing device; Simultaneously do not need to increase in addition the volume of said drilling pump 200 yet, can normal mounting use said lubricating fitting, therefore reduced the volume and the quality of whole drilling pump 200; And said lubricating fitting and said drilling pump 200 connect as one, the more convenient use and the transportation of said drilling pump 200; In addition; Each parts of said lubricating fitting all are installed on the said drilling pump 200; Effectively reduced the length of the pipeline 350 that is interconnected between each parts of said lubricating fitting, and the length of the pipeline 350 that is communicated with fuel tank 230 of lubricating fitting, the manufacture cost of having practiced thrift said drilling pump 200.
Disclosed arbitrary characteristic in this specification (comprising any accessory claim, summary and accompanying drawing) is only if special narration all can be replaced by other equivalences or the alternative features with similar purpose.That is, only if special narration, each characteristic is an example in a series of equivalences or the similar characteristics.
