At present, oilfield operation uses a large amount of fracturing unit trucks, cementing truck and well-washing truck, the said equipment is each equipped with high-pressure plunger pump and carries power source as fluid media (medium), existing high-pressure plunger pump many employings triplex or five cylinder pumps, laid out in parallel between cylinder body, cylinder number its pump housing volumes the most, weight, crankshaft length all significantly increase.Large volume and big weight equipment conveying and use, in gyration, effect of inertia makes bent axle produce larger vibration, and the overall mechanical performance of bent axle is greatly reduced.The cylinder body of triplex or five cylinder pumps is arranged on the upside of the pump housing more, occur that owing to cylinder body installation site is on the upper side pump housing center of gravity is higher and line shaft assembles the problems such as inconvenience, need to match change gear box and line shaft Matching installation, further increase the weight and volume of integral device.
Additionally, bent axle has been carried out improving to promote bent axle mechanical performance (such as patent name: Five-cylinder plunger pump crankshaft structure, application number: CN201220141150.0) by the plunger displacement pump of part triplex or five cylinder pumps.Bent axle arranges curved hollow cavity and reduces bent axle weight, reduce the vibration produced in gyration.But the shortcoming that in actually used, existing plunger displacement pump volume weight is big seriously constrains the conveyance fluid medium needing high pressure, huge discharge under production efficiency, particularly some special operation conditions, existing equipment cannot meet oilfield operation work requirements.
Utility model content
This utility model solves that the deficiencies in the prior art provide a kind of high pressure, huge discharge, volume is little, lightweight, the six cylinders opposed single-acting high-pressure plunger pump that operates steadily.
This utility model solves the technical scheme that its technical problem used:
A kind of six cylinders opposed single-acting high-pressure plunger pump, including pump case and power end, six cylinder bodies it are provided with in described pump case, power end is crankshaft connecting rod system, crankshaft connecting rod system includes that crankshaft-and-connecting-rod, driving shaft are located in the middle part of pump case, and driving shaft passes bent axle, driving shaft drives crankshaft connecting rod system motion, and crankshaft connecting rod system drives the acting of fluid power piston.
Through hole is offered on described bent axle, the through hole splicing composition cavity between bent axle, penetrate driving shaft in cavity.
On described bent axle, through-hole aperture is 180mm-200mm.
Described pump case arranged on left and right sides respectively arranges three cylinder bodies, is intervally arranged bent axle is left and right, angle 180 ° between adjacent bent axle.
Described driving shaft one end is connected with power source, the driving shaft other end is connected with sun gear, sun gear engages with planetary gear, sun gear drives planetary gear to rotate, and planetary gear also engages with gear ring, and planetary gear rotates around gear ring, planetary gear is fixing with planet carrier to be connected, planet carrier is followed planetary gear and is rotated, and planet carrier is set with crankshaft connecting rod system, and planet carrier drives crankshaft connecting rod system motion.
The beneficial effects of the utility model are:
1, this equipment is six cylinders opposed single-acting high-pressure plunger pump, is provided with six cylinder bodies in described pump case, and driving shaft is located in the middle part of pump case, compares traditional five cylinder pump driving shaft setting height(from bottom)s and have dropped 600mm, effectively reduces the center of gravity of pump, easy for installation, it is simple to maintenance.Power end is crankshaft connecting rod system, and crankshaft connecting rod system includes crankshaft-and-connecting-rod, arranges plunger and connecting rod in each cylinder body；Driving shaft drives crankshaft connecting rod system motion, and crankshaft connecting rod system drives the acting of fluid power piston.Driving shaft passes bent axle through hole；Reducing volume and weight, weight reduces 30%.Equipment is compacter, efficiently solves cylinder body one side and installs produced larger vibration, decreases the use of change gear box simultaneously, and equipment connects easier, and power transmission is more efficient.Achieve the high pressure of the 140Mpa of job requirements, 4.2-5m3The huge discharge of/min.
2, offer through hole on bent axle, in cavity, penetrate driving shaft.When revolutionizing existing crankshaft structure, driving shaft and crankshaft connecting rod system motion, vibration is greatly reduced.
3, in pump case, arranged on left and right sides respectively arranges three cylinder bodies, left and right between bent axle is intervally arranged, angle 180 ° between adjacent bent axle.Using six working cylinders, with 180 degree of levels to being arranged in crankshaft center both sides, effectively save table space, weight and volume are respectively less than five cylinder pumps, can realize high pressure, huge discharge, can reliably reach the market demand.Six horizontally-opposed arrangements of working cylinder are installed, and stable working is vibrated little；Bent axle overall dimensions shortens, and self-strength increases；The amount of force at two ends during bent axle work, direction are consistent, and uniform force significantly extends service life.
4, using one end power source input, the drive system supporting by the both ends of main drive shaft of installation in bent axle endoporus synchronizes, same-direction-driving dynamic crankshaft turns round, and makes loads on crankshaft uniform, reliable operation.
