Description
Technical field
The utility model belongs to mechanical equipment technical field, relates to integrated external lubricant passage way system in a kind of drilling pump.
Background technique
Lubricant oil mainly by oil pump supercharging, and by lubrication manifold, is transported to each lubricating point of pump by the power end of drilling pump lubricating system of current use.Wherein F series drilling pump is mainly divided into built-in feed lubrication and external feed lubrication, and built-in feed lubrication in pump chamber, arranges gear oil pump to provide lubrication pressure; External feed lubrication arranges an electric gear oil pump assy to provide lubrication pressure in the outer side of the pump housing.The oil pressure that single fuel system produces is less, and when carrying out pressure compensation without other oil supplying devices, the oil pressure of lubricating point is too low, easily occurs the phenomenons such as bearing temperature rise is high, guide plate insufficient lubrication, causes the damage of components of pump, shortens the working life of pump.
Model utility content
The purpose of this utility model is to provide integrated external lubricant passage way system in a kind of drilling pump, solve the lubricating oil path existed in prior art single, charge oil pressure is too low, causes each lubricating point effectively lubricating not enough, cause pump damage of components, shorten the problem in pump working life.
The technological scheme that the utility model adopts is, integrated external lubricant passage way system in a kind of drilling pump, in the inner chamber of the pump housing of drilling pump, be provided with gear oil pump, one end of this gear oil pump is communicated with oil absorption filter by fuel sucking pipe, and the other end is communicated with oil separator by oil inlet pipe three;
Outside the pump housing of drilling pump, be separately installed with oil pump assy one and oil pump assy two, wherein one end of oil pump assy one is communicated with the fuel sucking pipe one in pump chamber, and the other end of oil pump assy one is communicated with oil separator by oil inlet pipe one; One end of oil pump assy two is communicated with the fuel sucking pipe two in pump chamber, and the other end of oil pump assy two is communicated with oil separator by oil inlet pipe two; Oil separator is communicated to each lubricating point by multiple ram's horns.
Integrated external lubricant passage way system in drilling pump of the present utility model, is further characterized in that:
Oil separator is communicated with pressure gauge by a port, and oil separator is communicated with relief valve by another port.
The beneficial effects of the utility model are, this structure is used for F series drilling pump, interior external gear oil pump can singlely start, also can operate simultaneously, realize a kind of fuel system can not meet oil pressure requirement or break down when not working open running another gear oil pump carry out pressure compensation, can avoid like this because of fuel feeding oil pressure deficiency cause F series drilling pump damage.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the left side line of vision schematic diagram in Fig. 1.
In figure, the 1. pump housing, 2. oil pump assy one, 3. fuel sucking pipe one, 4. gear oil pump, 5. relief valve, 6. oil inlet pipe three, 7. oil separator, 8. oil absorption filter, 9. fuel sucking pipe two, 10. oil pump assy two, 11. oil inlet pipe one, 12. pressure gauges, 13. ram's hornss, 14. oil inlet pipes two.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
With reference to Fig. 1, Fig. 2, structure of the present utility model is, in the inner chamber of the pump housing 1 of (F series) drilling pump, be provided with built-in gear oil pump 4, one end of this gear oil pump 4 is communicated with oil absorption filter 8 by fuel sucking pipe, and the other end is communicated with oil separator 7 by oil inlet pipe 36; Be separately installed with oil pump assy 1 and the oil pump assy 2 10 of one group of electric gear wheel-type along axis both sides in the pump housing 1 periphery of drilling pump, wherein one end of oil pump assy 1 is communicated with the fuel sucking pipe 1 in pump chamber, and the other end of oil pump assy 1 is communicated with oil separator 7 by oil inlet pipe 1; One end of oil pump assy 2 10 is communicated with the fuel sucking pipe 29 in pump chamber, and the other end of oil pump assy 2 10 is communicated with oil separator 7 by oil inlet pipe 2 14; A port (passing through copper pipe) of oil separator 7 is communicated with pressure gauge 12, and another port of oil separator 7 is communicated with relief valve 5, and all the other ports of oil separator 7 are communicated to each lubricating point by multiple ram's horns 13.
Ram's horns, oil inlet pipe and fuel sucking pipe all adopt copper pipe material.
Working principle of the present utility model is,
When drilling pump normally works, built-in gear oil pump 4 operates, and oil pump assy 1 and oil pump assy 2 10 are closed condition, by gear oil pump 4 for each lubricating point provides oil pressure; When pressure gauge 12 shows hypotony, control system starts oil pump assy 1 or oil pump assy 2 10 immediately, and interior external oil pump operates simultaneously, carries out oil pressure compensation; When the running of gear oil pump 4 break down can not fuel feeding time, start oil pump assy 1 or oil pump assy 2 10, or start oil pump assy 1 and oil pump assy 2 10 to ensure lubrication pressure simultaneously.
In the utility model, integrated external lubricant passage way system is particularly suitable for F series drilling pump, interior external oil pump can be made to operate simultaneously, when the fuel system of inside can not meet oil pressure require or break down do not work time, the outside gear oil pump that can operate carries out pressure compensation, and the pump caused because of fuel feeding oil pressure deficiency can be avoided like this to damage.
