Description
Technical Field
The invention relates to the field of petroleum engineering equipment, in particular to a technical scheme for saving lubricating oil quantity of a drilling pump oil tank.
Background
The bore hole pump was invented in 1901 in the united states, and by the 70's last century, the united states developed bore hole pump technology to a very high level at that time, which now dominates bore hole pumps, to a certain extent, the development history of the united states bore hole pump represents the development history of the bore hole pump in the world, and the bore hole pump technology in all countries in the world was introduced from the united states, and not exception in china, and the bore hole pump in china is also dominated. In order to exceed the technology of the American well drilling pump, the technology of the American well drilling pump is analyzed, the essence is extracted, the dregs are removed, and then the technology of the American well drilling pump can exceed the United states, taking a W2200hp (with the power of 2200 hp) well drilling pump with the continuous operation performance of the W series of American camera company which is one brand of the American well drilling pump as an example, the price of the well drilling pump with the specification is 3 times that of the well drilling pump with the same specification in China, the 2400hp well drilling pump is developed in China at present, namely the well drilling pump with the W2200hp is required in all aspects, and the quantity of lubricating oil saved by an oil tank is exceeded. The service time of lubricating oil in the first break-in period of a W2200hp well pump of American cameron company is 250 hours, the service time of lubricating oil in the break-in period is 1000 hours, the quantity of lubricating oil added into each oil tank is required to be 799 liters, the lubricating oil is American lubricating oil, the most American lubricating oil is Mobil lubricating oil, the average price of Mobil lubricating oil sold in China is 100 RMB per liter, and the running cost is calculated according to the requirement: the cost of the lubricating oil per hour in the running-in period is 319.6 yuan, the cost of the operating lubricating oil per hour after the running-in period is 79.9 yuan, the operating cost of the visible lubricating oil is very high, the 2400hp novel well drilling pump developed in China has 200hp more power than the W2200hp of the American cameron company, the higher the power is, the more the quantity of the consumed lubricating oil is, if the using quantity of the lubricating oil of the W2200hp of the American cameron company is required, the using cost of the 2400hp novel well drilling pump lubricating oil is higher, therefore, the technical scheme for saving the quantity of the lubricating oil in the oil tank of the well drilling pump can be researched, not only can the using cost of the lubricating oil be reduced, but also the brightening can be manufactured for China.
Disclosure of Invention
The invention aims to provide a technical scheme for saving the quantity of lubricating oil in an oil tank of a drilling pump.
The technical scheme of the invention is as follows:
from the research on the basic functions of the oil tank as a breakthrough, the conventional thinking needs to be broken in the research process, and the research is specifically analyzed according to specific situations.
The basic functions of the fuel tank are: firstly, storing lubricating oil required by a lubricating system; precipitating water, solid and dirt in the lubricating oil; eliminating the foam of the lubricating oil; fourthly, the heat of the lubricating oil is dissipated. The first of the basic functions of the four aspects can certainly satisfy that the following three items are respectively adopted as follows:
the oil tank is changed from the frame into the base, the splash lubrication is cancelled and the oil tank, the crankshaft, the connecting rod, the gear, the crosshead and the bearing of the W2200hp well drilling pump of America cameron company are all in the closed frame box, the splash lubrication is adopted, namely in the closed box, the gear, the rolling bearing and the big end of the connecting rod which are soaked in the oil tank continuously stir the lubricating oil, the lubricating oil is continuously splashed on the friction surface of the rolling bearing between the pinion shaft and the frame, the bearing between the small end of the connecting rod and the crosshead pin and the sliding bearing between the crosshead and the frame, the lubricating oil is not filtered, the water, the solid and the dirt in the lubricating oil directly enter the friction pair, the abrasion between the metals of the friction pair is inevitably accelerated, in order to ensure that the water, the solid, the dirt and other substances at the bottom of the oil tank directly enter the friction pair when the stirring is not carried out, therefore, the depth of the oil tank must be very deep, the function of precipitating water, solids and dirt in the lubricating oil is large, the quantity of the lubricating oil is increased inevitably, and the improvement measures are that the oil tank is not designed in the frame and is arranged in the base instead, splash lubrication is cancelled, and forced lubrication is adopted completely, so that the depth of the oil tank can be reduced, namely the quantity of the lubricating oil is reduced.
In the base oil tank, the satisfaction measure of the function of precipitating the water in the lubricating oil is that a very low precipitation cavity is designed in the base oil tank, the precipitation cavity is not large, and the water in the precipitation cavity is discharged in time, so that the problem can be solved.
Solid in the lubricating oil, the filth is solved from the source, the solid and the filth source of lubricating oil have two aspects, first source is the base oil tank and does not have the solid of base oil tank before pouring into lubricating oil, the filth is clean, the base oil tank is formed by the welding, after surface treatment, solid in the base oil tank, the filth must exist, especially bottom welding juncture exists easily in the base oil tank, change new lubricating oil at every turn, if these places are difficult to clean, just remain in the base oil tank, consequently design into very easy clear base oil tank structure, can solve the problem of this first source. The second source is that during the operation of the drilling pump, the surfaces of bearings and gears are worn, the worn metal solids enter the lubricating oil, the lubricating oil has poor lubricating oil quality or poor use conditions, the lubricating oil is easy to oxidize, and insoluble matters and sediments such as oil sludge and paint films are generated by oxidation, and the oil sludge is a black and gray colloidal soft sediment. The second source is also solved from the source, the lubricating oil quality of W2200hp of America cameron company is high-end lubricating oil, the high-end lubricating oil quality needs to add good antioxidant additives into the lubricating oil, all bearing surfaces and gear surfaces are completely isolated by oil films, the abrasion is basically avoided, the oxidation speed of the lubricating oil is very slow, and the function is finished without a base oil tank, so the function of the base oil tank can be eliminated.
To eliminate the foam of the lubricating oil, the problem is solved from the source that the lubricating oil of W2200hp of America cameron company is added with an anti-foam additive with high quality in the lubricating oil, the foam eliminating effect of the lubricating oil is very good, and the lubricating oil is not easy to generate foam under good use conditions, so the function of eliminating the foam of the lubricating oil is also finished without a base oil tank.
The heat of the emitted lubricating oil is an important concern of the traditional oil tank design, the design of the volume of the oil tank is specially introduced in the mechanical lubrication design manual, namely, the heat productivity of a system and the heat dissipation capacity of the system are calculated, the volume of the oil tank is calculated from the heat balance angle, the heat dissipation capacity of the oil tank is in direct proportion to the surface area of the oil tank, the heat dissipation surface area of the oil tank is divided into two parts, one part is the surface area of the oil tank, the inside of the oil tank is soaked by the lubricating oil, the outside of the oil tank is cooled by the naturally circulating air, and the other part is the surface area of a reinforcing rib and a protrusion. The high-power drilling pump has high power and high heat productivity, and the surface area of an oil tank required by heat balance is necessarily large. The heat dissipation capacity of the novel drilling pump can balance the lubricating oil cooling system with the heat productivity of the system by means of the heat dissipation capacity, so that the heat dissipation function of the base oil tank for dissipating lubricating oil is cancelled.
According to the above analysis, the base oil tank mainly performs the function of storing the lubricating oil required by the lubricating system, and the functions of the other three aspects are weakened, and only the condition that the oil suction pipe opening of the base oil tank is lower than the surface of the lubricating oil to ensure that the lubricating oil cannot be sucked empty under any condition is met, namely, in any condition, when the drilling pump does not start to operate, the quantity of the lubricating oil in the base oil tank is large, but after the drilling pump operates, the lubricating oil enters each friction pair of the drilling pump from the base oil tank and then flows back to the base oil tank from each friction pair, namely, when the drilling pump operates, the quantity of the lubricating oil is reduced, the reduction is related to the return speed of the lubricating oil from each friction pair, the return speed is faster and less, otherwise, the return speed is slower, the quantity of the lubricating oil is more, the return speed of the lubricating oil is better, therefore, the oil tank plate of the base oil tank body is designed to have the inclination of 2-3 degrees, the inclination makes the speed of lubricating oil flowing back to the oil suction pipe opening of the base oil tank body faster, and the purpose of reducing the quantity of the lubricating oil is achieved.
Through the basic function analysis of the base oil tank, the base oil tank of the novel high-power drill pump only needs to be added with 300 liters of lubricating oil, the quantity of the lubricating oil is reduced by 62.5 percent compared with that of a W2200hp drill pump of America cameron company, and the cost of the lubricating oil in the operation of a user is reduced by 62.5 percent.

The improvement measure is that the oil tank is not designed in the frame, but is arranged in the base, splash lubrication is cancelled, and forced lubrication is adopted, so that the depth of the oil tank can be reduced, namely the quantity of lubricating oil is reduced.
The oil tank of novel well drilling pump changes inside the base, consequently calls the base oil tank, still belongs to the oil tank, from the basis that satisfies the basic function of oil tank as technical scheme, and the basic function of oil tank is: firstly, storing lubricating oil needed by a lubricating system; precipitating water, solid and dirt in the lubricating oil; eliminating the foam of the lubricating oil; fourthly, the heat of the lubricating oil is dissipated, the first basic function can be satisfied certainly, and the following technical schemes are adopted for the latter three items respectively.
Referring to fig. 1 to 4, the technical scheme for saving the amount of the lubricating oil in the oil tank of the drill pump in the embodiment includes a base oil tank body 1, a seal ring 2, a seal cover plate 3, an oil return port 1.1, an oil return port 1.2, an oil suction pipe port 1.3, a low-level left oil chamber 1.4, a low-level right oil chamber 1.5, a high-level right oil chamber 1.6, a high-level left oil chamber 1.7, a water sedimentation chamber 1.8, a water discharge port 1.9, a channel 1.10, an oil tank bottom plate 1.11, a channel 1.12, a longest width at a welding junction of the base oil tank 1.13, and a welding junction a.

Referring to fig. 1 to 4, the solid and dirt in the lubricant are solved from the source, the solid and dirt of the lubricant have two aspects, the first is that the solid and dirt of the base oil tank are not cleaned before the lubricant is injected into the base oil tank, the base oil tank is welded, and then surface treatment is performed, the solid and dirt in the base oil tank inevitably exist, especially the welding junction a of the base oil tank body 1 is easy to exist, the lubricant is replaced every time, if the places are not easy to clean, the places are kept in the base oil tank body 1, therefore, the base oil tank structure which is very easy to clean is designed, namely the welding junction a of the base oil tank body 1 is cleaned, the sealing cover plate 3 and the sealing ring 2 of fig. 1 are removed, because the longest width of the welding junction of the base oil tank is not more than 220mm, all places in the base oil tank body 1 can be cleaned very conveniently, the problem of the first source can be solved. The second source is that during the operation of the drilling pump, the surfaces of bearings and gears are worn, the worn metal solids enter the lubricating oil, the lubricating oil has poor lubricating oil quality or poor use conditions, the lubricating oil is easy to oxidize, and insoluble matters and sediments such as oil sludge and paint films are generated by oxidation, and the oil sludge is a black and gray colloidal soft sediment. The second source is also solved from the source, the lubricating oil quality of the W2200hp well drilling pump of the American camera on company is high-end lubricating oil, the high-end lubricating oil needs to be added with good antioxidant additives, all bearing surfaces and gear surfaces are completely separated by oil films, the abrasion is basically avoided, the oxidation speed of the lubricating oil is very slow, the function is not completed by a base oil tank, and therefore the function of the base oil tank can be eliminated.
To eliminate the foam of the lubricating oil, the problem is solved from the source that the lubricating oil of W2200hp of America cameron company is added with an anti-foam additive with high quality in the lubricating oil, the foam eliminating effect of the lubricating oil is very good, and the lubricating oil is not easy to generate foam under good use conditions, so the function of eliminating the foam of the lubricating oil is also finished without a base oil tank.
The heat dissipation capacity of the novel drilling pump can balance the lubricating oil cooling system with the heat productivity of the system by means of the heat dissipation capacity, so that the heat dissipation function of the base oil tank for dissipating lubricating oil is cancelled.
Referring to fig. 3, when the drill pump does not start to operate, the amount of the lubricating oil in the base oil tank body 1 is large, but after the operation, the lubricating oil enters each friction pair of the drill pump from the base oil tank body 1 and then returns to the base oil tank from each friction pair, i.e., when the drill pump operates, the amount of the lubricating oil is reduced, the reduction is related to the speed of the lubricating oil returning from each friction pair, the faster the speed of the returning is, the less the reduction is, the required lubricating oil amount ratio can be reduced, therefore, the oil tank bottom plate 1.11 of the base oil tank body 1 is designed to have an inclination of 2-3 degrees, and the inclination enables the lubricating oil to return to the oil suction pipe opening 1.3 of the base oil tank body 1 at a higher speed, so as to achieve the purpose of reducing the amount of the lubricating oil.
The basic function requirements of the oil tank can be met by combining the oil tank with the base from the inside of the rack to the inside of the base, designing a water sedimentation cavity 1.8 with the lowest position in the oil tank body 1 of the base and adopting a structure that all positions of the inner cavity of the oil tank body 1 of the base are very easy to clean, selecting lubricating oil with the same quality as that of lubricating oil of a W2200hp drilling pump of America cameron, configuring a lubricating oil cooling system with heat dissipation capacity capable of balancing the heat productivity of the system, and taking measures such as an oil tank bottom plate for accelerating the rapid return speed of the lubricating oil and the like, wherein the base oil tank of the novel drilling pump only needs 300 liters of lubricating oil, the quantity of the lubricating oil is reduced by 62.5 percent compared with that of the lubricating oil of the W2200hp drilling pump of the America cameron, and the cost of the lubricating oil in the operation of a user is reduced by 62.5 percent.
