Technical field
This utility model relates to the pressure break pump truck used by field of petroleum machinery, belongs to a kind of novel lubrication system being applicable to power end of fracturing pump lubrication.
Background technology:
Fracturing process is that people utilize ground high pressure pump truck group, high viscosity liquid i.e. fracturing fluid is injected in well with the discharge capacity substantially exceeding formation absorption ability, high pressure has been suppressed near shaft bottom, when this pressure exceedes near the borehole wall after the anti-intensity that rises of reservoir stress and rock, stratum extruding crack, and proppant is injected in crack, these cracks have the highest penetrating power, significantly improve the permeability of oil-gas Layer, play increasing yield and injection effect.Pressure break pump truck is one of capital equipment in pressing crack construction process, and wherein fracturing pump is one of core component of pressure break pump truck, and the quality of fracturing pump entirety lubricant effect will directly affect using effect and the service life of pressure break pump truck；The lubrication of fracturing pump is divided into power end lubricating system and hydraulic end lubricating system two parts, before novel power end of fracturing pump lubricating system uses, power end of fracturing pump lubricating system uses and is directly arranged on the PTO interface of transmission case by grease pump, and only arranges one-level safety device on lubricating system pipeline；Because grease-box is typically located at fracturing pump chassis side and rearward, the grease pump being arranged on transmission case is then in the front portion of pressure break pump truck and far above plane on chassis ridgepole so that fuel sucking pipe line length, lubricating pump to fracturing pump distance is far；There is the phenomenons such as grease pump oil absorbing effect is the best, lubrication pressure fluctuation is big, lubrication management linearly coupled is big in the structure and layout of traditional power end lubricating system, thus cause whole power end lubricating system easily to produce cavitation and hydraulic shock phenomenon, have a strong impact on the lubricant effect of power end of fracturing pump.
Utility model content
The purpose of this utility model is to overcome power end lubricating pump directly power taking and the shortcoming of conventional lubrication mode safeguard protection deficiency from transmission case; ensure the stationarity of power end of fracturing pump lubrication and good lubricant effect, be prevented effectively from lubricating system and produce the phenomenon such as hole and hydraulic shock；Design this utility model power end of fracturing pump lubricating system.
To achieve these goals, the following technical scheme that this utility model have employed.
A kind of lubricating system being applicable to power end of fracturing pump, is mainly made up of hydraulic oil container, hydraulic oil pump, relief valve I, hydraulic oil-returning filter, hydraulic motor, grease pump, oil absorption filter, relief valve II, tubular filter, temperature-conserving valve, relief valve III, radiator, pressure transducer, relief valve IV, fracturing pump, temperature sensor, grease-box；It is characterised by: hydraulic oil pump obtains power by the PTO interface on transmission case, from hydraulic oil container, suck hydraulic oil be used for driving hydraulic motor, when higher than hydraulic motor maximum working pressure (MWP), high pressure liquid force feed flows through relief valve I, hydraulic oil-returning filter returns in hydraulic oil container；Hydraulic motor obtains after power thus drive installation grease pump near grease-box, grease pump sucks lubricating oil through oil absorption filter, from grease pump out after lubricating oil stream first pass through first order safety device relief valve II and be then passed through tubular filter and arrive at temperature-conserving valve；When lubricating oil temperature is higher than the temperature set by temperature-conserving valve, lubricating oil stream first passes through second level safety device relief valve III and enters back into radiator, and lubricating oil flows through third level safety device relief valve IV after heat radiation, finally arrives at power end of fracturing pump；When lubricating oil temperature is less than the temperature set by temperature-conserving valve, lubricating oil is directly over 3rd level safety device relief valve IV, then enters back into power end of fracturing pump, and lubricating oil returns to grease-box by being arranged on the oil return pipeline bottom fracturing pump again；Utilizing hydraulic line, lubrication pipeline, joint etc. main parts size to be coupled together, power end of fracturing pump new type of continuous pressure oil formula forcedlubricating system has just been set up.
One-level safety device it is provided with for protecting hydraulic motor in the hydraulic circuit of lubricating system; three level security devices it are provided with in the lubricant passage way of lubricating system; pressure release value is configured from high to low, and first order safety device relief valve II is for stablizing the pressure of lubricating oil stream, second level safety device relief valve III for protecting radiator, third level safety device relief valve IV to enter the lubrication pressure of power end of fracturing pump for stable and regulation.
Lubricating oil simultaneously enters from the power end of fracturing pump left and right sides, and installs pressure transducer in the feed line of power input side, mounting temperature sensor on the oil return supervisor bottom fracturing pump.
Hydraulic motor is directly bound up by bolt with grease pump, and is fixed on the place that distance grease-box is the nearest together, reaches the purpose that oil absorbing effect is good.
The utility model has the advantage of: novel power end of fracturing pump lubricating system can improve stability and the reliability of power end of fracturing pump lubrication, it is thus achieved that good lubricant effect, improves the safety of lubricating system hardware；Lubricating system can be prevented effectively from and produce the phenomenon such as hole and hydraulic shock, also can extend the service life of the vitals such as radiator, fracturing pump, grease pump simultaneously.
