Abstract
The utility model provides a fracturing unit truck power end lubricating system of horizontal water tank overall arrangement, includes the engine, lubricating -oil tank, hydraulic pump, hydraulic motor, lubricant pump, radiator, fracturing pump. The power transmission system: the hydraulic pump is the power of getting before the engine, the work of drive hydraulic motor, and the motor directly links drive lubricant pump, lubricating oil pipe way: the lubricant pump, is supplied with and is given fracturing pump lubrication, lubricant pump oil return to one set of closed cycle pipeline of oil tank behind the radiator from the lubricating -oil tank oil absorption.
Description
Technical field
The utility model is related to field of hydraulic control, the fracturing unit truck power end lube system of particularly a kind of horizontal water tank layout
System.
Background technology
Pressing crack construction operation is the important means for transforming oil-gas reservoir, and fracturing unit truck is the capital equipment of pressing crack construction, its work
With being that huge discharge is injected into stratum, the liquid of high pressure ruptures stratum extruding, and the supporting material agent in liquid is entered into crack,
In-place permeability is improved, the rate of oil and gas recovery is improved.
Fracturing pump will be passed through as the crucial vitals of fracturing unit truck from ride engine and Side Gearbox Transmission System
The mechanical energy of power transmission shaft input, then huge discharge is changed to, the hydraulic energy of high pressure plays irreplaceable effect.Need a set of peace
Complete reliable cooling and lubricating system, is the continual and steady offer lubrication of the inner body of fracturing pump, while by pressure break pump work
The heat energy of generation carries out cooling process.
Current cooling and lubricating system, power source adopts gearbox power taking, and the entrance of pump is with the difference in height of fuel tank in 500 millis
It is more than rice, meanwhile, the viscosity rank of lubricating oil is heavily loaded rank, causes the suction capacity of pump very poor, the use longevity to fracturing pump
Life is greatly to reduce.
The water tank of horizontal layout to lubricating pump and the top of fracturing pump, at least more than 1.5 meters of difference in height, in hydraulic pump to oil
Dissipate, oil is dissipated in the pipeline of fracturing pump lubrication, and after shutdown soon, the liquid in pipeline can be emptied, and cause air to be full of in pipeline
In, in follow-up equipment use, cause lubrication pressure to need emptying, emptying not thoroughly, to cause oil pressure less than lubricating requirement, make
Damage into fracturing pump, be forced maintenance down, occasion a delay to the continuous operation of fracturing unit truck, cause operation quality to reduce.
Utility model content
The problem of solution is required for the utility model：A kind of simple structure, easy to operate, good airproof performance are provided, are boiled medicine
Efficiency high, the fracturing unit truck power end lubricating system for using safe, easy to maintenance horizontal water tank layout.
To solve above-mentioned technical problem, the utility model makes to realize with the following method：A kind of pressure break of horizontal water tank layout
Car power end lubricating system, including hydraulic oil pump (1), hydraulic motor (2), grease pump (3), temperature-sensing valve (4), check valve (5),
Radiator (6), fracturing pump (7), safety valve (8), hydraulic oil container (9) and fuel tank (10)；
The suction inlet of hydraulic oil pump (1) connects hydraulic oil container (9), and the outlet of hydraulic oil pump (1) connects hydraulic motor (2), is formed
Hydraulic circuit；Outlet parallel connection safety valve (8) of hydraulic oil pump (1), hydraulic motor (2) drives grease pump (3)；Lubricating oil
The suction inlet connected tank (10) of pump (3), grease pump (3) outlet connects temperature-sensing valve (4), and temperature-sensing valve (4) connects check valve (5), radiating
Device (6) outlet connects check valve (5), and check valve (5) connects fracturing pump (7), fracturing pump (7) connected tank (10).
Utility model good effect：It is intended to persistently keep the service life cycle of hydraulic pump, while removing in lubricating system
Air, eliminate because oil pressure of lubricating system can not be continual and steady, cause fracturing unit truck group job quality reduce impact.
Description of the drawings
Fig. 1 is lubrication system architecture frame diagram.
Fig. 2 is lubricating system hydraulic schematic diagram.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and detailed description.
As shown in Figure 1-2, the fracturing unit truck power end lubricating system of a kind of horizontal water tank layout described in the utility model, bag
Include hydraulic oil pump (1), hydraulic motor (2), grease pump (3), temperature-sensing valve (4), check valve (5), radiator (6), fracturing pump
(7), safety valve (8), hydraulic oil container (9) and fuel tank (10).
The suction inlet of hydraulic oil pump (1) connects hydraulic oil container (9), and the outlet of hydraulic oil pump (1) connects hydraulic motor (2), is formed
Hydraulic circuit.Outlet parallel connection safety valve (8) of hydraulic oil pump (1), hydraulic motor (2) drives grease pump (3).Lubricating oil
The suction inlet connected tank (10) of pump (3), grease pump (3) outlet connects temperature-sensing valve (4), and temperature-sensing valve (4) connects check valve (5), radiating
Device (6) outlet connects check valve (5), and check valve (5) connects fracturing pump (7), fracturing pump (7) connected tank (10).
The utility model beneficial effect is：
1. power taking before hydraulic pump-motor, hydraulic oil flows into the pump housing under deadweight, is mixed in pipeline without air, and oil pressure is steady
It is fixed.
2. the height of lubricating pump is positioned as needed flexibly, is eliminated because difference in height is improper, causes the hypodynamic shadow of self-priming
Ring, each element in protection lubricating pump inside.
3. radiator inlet and outlet increase check valve, it is ensured that in pipe pipeline air emptying, there is provided lubricating system it is steady
It is qualitative.
Claims (1)
1. the fracturing unit truck power end lubricating system of a kind of horizontal water tank layout, it is characterised in that including hydraulic oil pump (1), hydraulic pressure
Motor (2), grease pump (3), temperature-sensing valve (4), check valve (5), radiator (6), fracturing pump (7), safety valve (8), hydraulic oil
Case (9) and fuel tank (10)；
The suction inlet of hydraulic oil pump (1) connects hydraulic oil container (9), and the outlet of hydraulic oil pump (1) connects hydraulic motor (2), forms hydraulic pressure
Closed circuit；Outlet parallel connection safety valve (8) of hydraulic oil pump (1), hydraulic motor (2) drives grease pump (3)；Grease pump
(3) suction inlet connected tank (10), grease pump (3) outlet connects temperature-sensing valve (4), and temperature-sensing valve (4) connects check valve (5), radiator
(6) outlet connects check valve (5), and check valve (5) connects fracturing pump (7), fracturing pump (7) connected tank (10).
