Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technological scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
Please refer to Fig. 2 to Fig. 4, described drilling pump 200 comprises base 210, frame 220, fuel tank 230 and cross lap 240; Described base 210 stands on ground, and described frame 220 is installed on described base 210, thus described base 210 coordinate with described frame 220 together with firmly support other parts of described drilling pump 200; Described fuel tank 230 is arranged on described base 210, is contained with lubricant oil in described fuel tank 230, lubricates for the cylinder sleeve piston of described drilling pump 200, ensures the normal work of described drilling pump 200; Described cross lap 240 is removably installed in described frame 220, overhauls, and be formed with containing space 201 between described cross lap 240 and base 210 to be easy to open the associated components of described cross lap 240 to described drilling pump 200.Described lubricating fitting is installed on described drilling pump 200, and described lubricating fitting is communicated with described fuel tank 230, thus the cylinder sleeve piston by described lubricating fitting the lubricant oil in described fuel tank 230 being sent to after respective handling described drilling pump 200 lubricates.Wherein, specific structural features and the performance effect of described drilling pump 200 and all parts thereof are well known to the skilled person, in this no longer repeated description.
Particularly, described lubricating fitting comprises coarse-grain filtering device 310, oil pump 320, fine filter 330 and cooler 340, and described coarse-grain filtering device 310, oil pump 320, fine filter 330 and cooler 330 is by pipeline 350 sequential communication successively, and make described fuel tank 230 be communicated to the cylinder sleeve piston of described drilling pump 200, thus the oil circuit that composition one is complete, with the lubricant oil transmitted in described fuel tank 230, described cylinder sleeve piston is lubricated.Described coarse-grain filtering device 310 is installed on the side of described frame 220, and described coarse-grain filtering device 310 is communicated with described fuel tank 230 by pipeline 350, thus described coarse-grain filtering device 310 carries out primary filter, with the more coarse impurity carried in filtering lubricant oil to the lubricant oil flowing out described fuel tank 230; Described oil pump 320 is installed on the side of described base 210, the filler opening of described oil pump 320 is communicated with described coarse-grain filtering device 310 by described pipeline 350, thus described oil pump 320 provides power for flowing fuel tank 230 described in outflow of lubrication oil, lubricant oil is sent on the required parts used; In a preferred embodiment of the invention, described coarse-grain filtering device 310 and described oil pump 320 are positioned at the same side (see figure 4) of described base 210 or frame 220, thus can reduce to connect the pipeline 350 between described coarse-grain filtering device 310 and oil pump 320, reduce the cost of production of whole described drilling pump 200; The two ends of described fine filter 330 are communicated with the oil outlet of described oil pump 320 and the filler opening of cooler 340 respectively by pipeline 350, described fine filter 330 filters again to the lubricant oil flowed out in described oil pump 320, with the various impurity that may carry in filtering lubricant oil, to ensure the turbidity test of lubricant oil, improve the lubrication effect to described drilling pump 200 cylinder sleeve piston; Described fine filter 330 is installed in described containing space 301, thus do not need other space taking described drilling pump 200 to install described fine filter 330, and the free space that effectively make use of in described containing space 301, further reduce the volume of whole drilling pump; Described cooler 340 is installed on described cross lap 240, described cooler 340 is connected to described cylinder sleeve piston by pipeline 350, thus described cooler 340 cools the lubricant oil after again filtering through described fine filter 330, and cooled lubricant oil is sent on described cylinder sleeve piston, to ensure the temperature requirement of cylinder sleeve piston to lubricant oil, improve the effect that cylinder sleeve piston is lubricated further; And described cooler 340 is installed on described cross lap 240, effectively make use of the free space on described cross lap 240, do not need the volume increasing described drilling pump 200 to get final product cooler 340 described in normal mounting, reduce volume and the weight of whole described drilling pump.
As a preferred embodiment of the present invention, described in each, pipeline 350 is steel pipe, uses steel pipe as pipeline, its longer service life, can ensure that the long-term delivery of lubricant oil transports; And steel pipe is arranged on described drilling pump 200, layout more neatly compactly, not only facilitates transport but also makes the overall appearance of drilling pump more attractive in appearance.
The described lubricating fitting for drilling pump of the present invention is respectively arranged with two coarse-grain filtering devices 310, fine filter 330 and cooler 340, and described oil pump 320 is set to one, thus can form two complete oil circuits, namely reflux oil circuit with transmit oil circuit; Described transmission oil circuit is made up of described coarse-grain filtering device 310, oil pump 320, fine filter 330, cooler 340 and pipeline 350, is sent to by the lubricant oil in described fuel tank 230 on described cylinder sleeve piston, to lubricate cylinder sleeve piston, as detailed above; Described in described withdrawing oil route, coarse-grain filtering device 310, fine filter 330, cooler 340 and pipeline 350 form, in oil return after this oil circuit makes lubrication complete to described fuel tank 230, to repeat to utilize, the detailed process of this oil circuit work is identical with described transmission oil circuit, difference is only not use oil pump 320, because the oil mass of backflow is relatively less, so oil circuit does not need to use oil pump 230 can make in lubricant oil natural back flow to described fuel tank 230, therefore, the carrying out practically process of backflow oil circuit is no longer specifically described.
From the above, lubricating fitting for drilling pump of the present invention is directly installed on described drilling pump 200, make when installing described lubricating fitting, do not need to arrange bearing device in addition, not needing the volume increasing described drilling pump 200 in addition simultaneously, normal mounting can using described lubricating fitting, because this reducing volume and the quality of whole drilling pump 200 yet, and described lubricating fitting and described drilling pump 200 connect as one, the use of more convenient described drilling pump 200 and transport; In addition, each parts of described lubricating fitting are all installed on described drilling pump 200, effectively reduce the length of the pipeline 350 be interconnected between each parts of described lubricating fitting, and the length of pipeline 350 that lubricating fitting is communicated with fuel tank 230, save the manufacture cost of described drilling pump 200.
Arbitrary feature disclosed in this specification (comprising any accessory claim, summary and accompanying drawing), unless specifically stated otherwise, all can be replaced by other equivalences or the alternative features with similar object.That is, unless specifically stated otherwise, each feature is an example in a series of equivalence or similar characteristics.
