Technical field
The invention belongs to petroleum drilling and mining equipment technology field, relate to a kind of hydraulic driving dry oil lubrication pump.
Background technique
Supporting powerful device One's name is legion on oil-well rig, mechanical parts tie point is more, the a large amount of human cost of cost is needed regularly to go to add grease injection to a large amount of dry oil lubrication point, and the extensive mode of hand oiling fat and waste of manpower and appropriate grease up in time can not be accomplished, easily cause the position oil starvation wearing and tearing such as bearing and premature deterioration.
Summary of the invention
The object of this invention is to provide a kind of hydraulic driving dry oil lubrication pump, solve on existing drilling equipment and adopt human at periodic intervals to add grease injection, waste time and energy, and the problem that lubrication effect is undesirable.
The technical solution adopted in the present invention is, a kind of hydraulic driving dry oil lubrication pump, comprise double piston cylinder oil hydraulic cylinder, double piston cylinder oil hydraulic cylinder one end piston rod is connected with the connecting rod of limit stoper, double piston cylinder oil hydraulic cylinder the other end piston rod is connected with single-piston rod cylinder piston rod, the adsorbent chamber outlet passage of single-piston rod oil cylinder is provided with oil outlet one-way valve, and the adsorbent chamber inlet passage of single-piston rod oil cylinder is provided with oil sucting one-way valve, the end of oil sucting one-way valve and pressure feed lubrication oil drum lower end outlet.
Hydraulic driving dry oil lubrication pump of the present invention, its feature is also:
Pressurized lubrication oil barrel cavity top is installed with spring, and lower spring end is connected with pressing plate, and lubricant grease is filled in the space below pressing plate.
The invention has the beneficial effects as follows, utilize hydraulic system and automatical control system that oil-well rig is furnished with, adopt hydraulic energy as the piston rod of motivational drive hydraulic cylinder with double piston rods stretch out/retract drive single-piston rod oil cylinder by lubricant grease from Lubricating oil barrel suction pump, the control of single being pumped/sucking oil quantity is realized by the restriction of piston rod stroke, set up the suction of spring increase oil hydraulic cylinder to grease on Lubricating oil barrel top prevent single-piston-rod hydraulic cylinder from inhaling sky simultaneously, one-way valve is established to prevent the backflow of grease at Lubricating oil barrel oil outlet, can be applicable to the grease lubricating system of the equipment being with hydraulic transmission and automatical control system system, the convenient automatic control realizing lubrication, easily realize grease centralized lubrication and automatically quantitative lubrication, improve rig automation degree, save manpower and materials cost.
Accompanying drawing explanation
Fig. 1 is the structural representation of apparatus of the present invention.
In figure, 1. limit stoper, 2. double piston cylinder oil hydraulic cylinder, 3. single-piston rod oil cylinder, 4. oil outlet one-way valve, 5. pressure feed lubrication oil drum, 6. oil sucting one-way valve.
Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.
With reference to Fig. 1, the structure of apparatus of the present invention is, comprise double piston cylinder oil hydraulic cylinder 2, double piston cylinder oil hydraulic cylinder 2 one end piston rod is connected with the connecting rod of limit stoper 1, double piston cylinder oil hydraulic cylinder 2 the other end piston rod is connected with single-piston rod oil cylinder 3 piston rod, the adsorbent chamber outlet passage of single-piston rod oil cylinder 3 is provided with oil outlet one-way valve 4, and the adsorbent chamber inlet passage of single-piston rod oil cylinder 3 is provided with oil sucting one-way valve 6, the end of oil sucting one-way valve 6 and pressure feed lubrication oil drum 5 lower end outlet.
The two ends of hydraulic cylinder with double piston rods 2 are respectively arranged with a piston rod, each rod end chamber is communicated with independently hydraulic oil inlet (as the A mouth in Fig. 1 and B mouth), these two hydraulic oil inlet are all connected with the HYDRAULIC CONTROL SYSTEM that oil-well rig configures, adopt hydraulic energy stretching out/retracting as the piston rod of motivational drive hydraulic cylinder with double piston rods 2, drive single-piston rod oil cylinder 3 that lubricant grease is pumped/sucked from oil drum (realizing oily or oil return as the C mouth Fig. 1 coordinates).
The hydraulic oil of A mouth, B mouth and C mouth is by hydraulic control system cooperation control.
The connecting rod of limit stoper 1 has the stroke of setting, and the trip correspondence of limit stoper 1 controls (being moved to the left) range of double piston cylinder oil hydraulic cylinder 2 piston rod, realizes the control of single being pumped to oil quantity.
Pressure feed lubrication oil drum 5 inner chamber top is installed with spring, lower spring end is connected with pressing plate, lubricant grease is filled in space below pressing plate, pressing plate is under the expansion force effect of spring, all the time the lubricant grease in pressure feed lubrication oil drum 5 is extruded downwards, make lubricant grease be in extrusion state all the time, prevent single-piston rod oil cylinder 3 " inhaling empty ".
The working principle of apparatus of the present invention is,
When needing charging-up lubricant oil fat, the high pressure oil of hydraulic control system flows into (B mouth flows out) from A mouth simultaneously and drives the piston rod of hydraulic cylinder with double piston rods 2 to move right, the C mouth of single-piston rod oil cylinder 3 comes oily, the compression of the piston rod of single-piston rod oil cylinder 3 is gone back, the adsorbent chamber space of single-piston rod oil cylinder 3 diminishes, due to the single effect of oil sucting one-way valve 6, lubricant grease is forced to be pumped to " grease outlets " with elevated pressures by oil outlet one-way valve 4;
After grease pumps completely, the high pressure oil of hydraulic control system flows into (A mouth flows out) from B mouth simultaneously and drives the piston rod of hydraulic cylinder with double piston rods 2 to be moved to the left, the piston rod of single-piston rod oil cylinder 3 is stretched out, the C mouth oil return of single-piston rod oil cylinder 3, the adsorbent chamber space of single-piston rod oil cylinder 3 becomes large, under the spring pressure of adsorbent chamber negative pressure and pressure feed lubrication oil drum 5, oil outlet one-way valve 4 cuts off " grease outlets " direction oil return, oil sucting one-way valve 6 is opened from " oil suction " pressure feed lubrication oil drum 5, lubricant grease is made to enter adsorbent chamber with elevated pressures by " grease import ", simultaneously limit stoper 1 limits the range of hydraulic cylinder with double piston rods 2 piston rod, realizes the control to A Single Intake by Inhalation/pump oil quantity.
