Abstract
The utility model relates to a special fluid coupler energy saving device for oil pumping machines, which is used for oil pumping machines for improving the working conditions and saving energy and is composed of a housing 1, a driving impeller 2, a driving shaft 3, a bearing 4, a driven impeller 5, a front end cover 6, a back end cover 7, an oil feeding port screw plug 8, a safety protective plug 9, a connecting bolt 10, and an oil seal 11. The utility model can be utilized to realize the purposes that oil pumping machines can be started in the state of nealy without loads, the electric energy is saved, the working conditions of oil pumping machines can also be improved, the stroke frequency is convenient for regulation, the overload protection is provided, and the faults that belts slide and are damaged, etc. are avoided.
Description
The utility model relates to and a kind ofly is used for the pumping unit transmission, working procedure is improved working condition and energy-conservation device.
Pumping unit is the visual plant of mechanical oil recovery.At present, the pumping unit that mining site adopts lacks additional energy-conservation and overload protection device, thereby bigger because of load when starting, and starting current is higher, and electrical network is formed than thump; In course of normal operation, then because of the load frequent variations, pumping unit overall work situation is stable inadequately, and the impact that each component bore, vibration are bigger, and be affected its mechanical life.In addition because existing pumping unit adopts belt transmission mostly, exist to some extent easy to wear, skid, transmission efficiency is lower, adjust shortcomings such as jig frequency operating difficulties.
The purpose of this utility model is to provide a kind of can reduce starting current, improve the special-purpose hydraulic couplers energy saving device of pumping unit that the pumping unit working condition also can provide overload protection, be convenient to adjust jig frequency.
The utility model is to realize like this.This device adopts the hydraulic couplers structure, form by shell, driving shaft, bearing, active impeller, passive impeller, front cover, rear end cover, oil filler plug, safety protection plug, attachment bolt, oil sealing, its structure, the assembling feature as follows: driving shaft traverses setting in the enclosure, initiatively impeller is housed on it, passive impeller and shell that second half shell of double as is used connect, and fix with Bolt Connection; The shell and the passive impeller outside are equipped with front cover and rear end cover respectively, and fix with Bolt Connection; Between driving shaft and shell, passive impeller are coaxial bearing is housed respectively, oil sealing is equipped with at the position, gap between driving shaft and shell, passive impeller, the forward and backward end cap respectively; Two relative radially oil fillers of shell are provided with plug, are provided with the safety protection plug in the side direction screw of two symmetries.Before the work, this device driving shaft is cooperated fixing with the pumping-unit motor axle with fixing bolt, and dock fixing with pumping unit transmission chain wheel or belt pulley this device rear end cover with attachment bolt, behind the transmission oil of injection as the hydraudynamic drive working medium, can devote oneself to work by actuating motor in this device cavity from oil filler.During work, the active impeller rotation on the driving shaft that motor drives links with it, initiatively wheel rotation makes the transmission oil in the cavity produce kinetic energy, passes to passive impeller rotation, and drives drive sprocket or the belt pulley rotation that links with it.Like this, according to said process, the power of motor is transferred to sprocket wheel or belt pulley by driving shaft, active impeller, driving medium, passive impeller successively.The working principle of this device is as follows: during starting, because the working medium major part is not on circulate circle, thereby the electric motor starting electric current is lower, when motor forwards to a certain degree, working medium just can be distributed to and enter proper functioning on the circulate circle, thereby the working condition when having improved electric motor starting approaches No Load Start.This device is provided with certain overload coefficient, when overload is slowed down, speed reducer input shaft rotating speed is zero, when Coupler working medium temperature is increased to specified value, the safety protection plug comes off, can automatic draining, cause motor idle running, thereby protected motor and pumping unit.
The utility model adopts the hydraulic couplers structure, can realize that pumping unit near zero load starting, reduces starting current, alleviates the impact to electrical network, but and the rational Match power of motor, prevent " low load with strong power ", saving power.Adopting this device can change the belt of oil pumping machine transmission is chain-driven, improves the complete machine working efficiency, avoids faults such as belt slippage, damage, and this device also has can provide overload protection, be convenient to adjust advantage such as jig frequency, is suitable for and applies.
Accompanying drawing is a structural representation of the present utility model.Among the figure, label " 12 ", " 13 " are respectively motor shaft and axle fixing bolt, and " 14 " are the pumping unit drive sprocket.
Below in conjunction with accompanying drawing enforcement of the present utility model is illustrated.
As shown in the figure, the utility model is made up of shell 1, active impeller 2, driving shaft 3, bearing 4, passive impeller 5, front cover 6, rear end cover 7, oil filler plug 8, safety protection plug 9, attachment bolt 10, oil sealing 11.Wherein, shell 1 is upright hollow dome body; its limit portion is arranged with band respectively and twists radially oil filler and the side direction safety protection consent of plug with screw thread, and top, bottom and and arranged on left and right sides are respectively equipped with passive impeller that second half shell of double as uses and match and connect the screw of usefulness.Initiatively impeller 2 is the hollow wheel-shaped body, is uniformly distributed with 12--72 sheet blade on it along the circumference.Driving shaft 3 is a hollow cylinder, and its periphery is provided with 4 places assemblings and use step, inner headed face one side to be provided with to be screwed into a fixing bolt screw, and the middle part is provided with and motor shaft assembles and uses step.Passive impeller 5 appearance profiles and shell 1 match, and in fact are be cast with on it and second half shell of impeller similar number blade initiatively.
