Description
Technical field
The utility model belongs to the injection pump technical field, and what relate generally to is a kind of oiling machine for steel-wire rope injection pump.
Technical background
Wire rope is a very wide industrial product of purposes, and the corrosion of wire rope and wearing and tearing are one of principal modes of wire rope inefficacy, and preventing or reducing corrosion and wear and tear is the main path that prolongs rope service-life.Usually, wire rope has anticorrosion grease at its wire rope core and surface impregnation when dispatching from the factory, and with lubricated wire rope inside, reduces the wearing and tearing between the steel wire, stops the intrusion of water, prevents the wire rope corrosion.But in use anticorrosion grease can be extruded gradually, come off and lose antisepsis.Therefore, to according to circumstances in time replenish anticorrosion grease in the use.
At present, the way of additional anticorrosion grease mainly contains two kinds: a kind of is with manually oiling on wire rope.The major defect of this method is grease can't be pressed into wire rope inside, can't prevent the corrosion of wire rope inside, and oiling efficient is low, and labor intensity is big.Another kind is to use Lubricators that grease is pressed into wire rope inside, and simultaneously also in surface-coated, this method is laborsaving, high working efficiency.
Lubricators in the past adopts the oiling of pressure injection cylinder, do not possess self-absorption function, need join a dry oil pump in addition pumps into the wire rope grease in the pressure injection cylinder, and then the grease in the pressure injection cylinder is pressed in the wire rope with hydraulic coupling, need use dry oil pump pump oil again after the grease in the pressure injection cylinder has been annotated, therefore, this kind Lubricators can not continuous operation, troublesome poeration during especially to the oiling simultaneously of many wire rope, efficient is low.
In addition, common hydraulic system can only be used the lower hydraulic oil of viscosity, and the wire rope grease with viscosity higher can not be directly used in the system; Though conventional dry oil pump is applicable to the wire rope grease that viscosity is higher, its outlet pressure lower (generally being lower than 2MPa) can not satisfy the requirement of wire rope oiling.
Summary of the invention
The purpose of this utility model promptly produces thus, proposes a kind of oiling machine for steel-wire rope injection pump.Make its oiling requirement of satisfying wire rope, but and continuous operation, have simple to operate, reliable, the characteristics that efficient is high.
For achieving the above object, the technological scheme that the utility model is taked is: spacer sleeve is divided into left and right two cylinder bodies with the pump housing in being provided with in the pump housing, in left cylinder, be provided with left piston, in right cylinder body, be provided with right piston, this two-piston is fused by piston rod, thus the pump housing is separated into four independently oil pockets, promptly is positioned at two hydraulic driving chambeies in the outside and is positioned at two inboard grease chambeies; The bi-side of middle spacer sleeve respectively are provided with filler opening and the oil outlet that pilot operated directional control valve is communicated with the grease chamber, and the outer surface of middle spacer sleeve is provided with pilot operated directional control valve control port, pouring orifice and inlet port; The two ends of the pump housing are sealed by cylinder cap.
The injection pump that the utility model proposes adopts hydraulic driving, possesses self-absorption function, can be 6000mm with kinematical viscosity
2In the following grease suction pump of/s, and extrude with upward pressure, can satisfy the requirement of wire rope oiling fully with 4MPa; Its to-and-fro motion design, but continuous operation; Built-in pilot operated directional control valve has promptly reduced external connecting pipe road and line loss when guaranteeing timely, reliable commutation, reduced the volume and weight of injection pump again.
It is ingenious, reasonable to the utlity model has structural design, security of operation, reliable, and characteristics such as working efficiency height are applicable to that grease viscosity is higher and need the occasion that high pressure is exported.

Embodiment
In conjunction with the accompanying drawings, it is as follows to provide embodiment of the present utility model:
As shown in Figure 1: present embodiment is that spacer sleeve 4 makes the pump housing be divided into left cylinder 2 and right cylinder body 6 in being provided with in the pump housing, middle spacer sleeve 4 is provided with selector valve control port 9,10, right grease chamber filler opening 13, right grease chamber oil outlet 14, left grease chamber filler opening 15, left grease chamber oil outlet 16 and pouring orifice 17 and inlet port 18.Wherein be provided with left piston 3 in left cylinder 2, be provided with right piston 76 li of right cylinder bodies, left piston 3 and right piston 7 are fused by piston rod 5, and two ends are respectively by left cylinder cap 1 and 8 sealings of right cylinder cap.Thus the pump housing is separated into four independently oil pockets, promptly Wai Ce two oil pockets are the hydraulic driving chamber, and two inboard oil pockets are grease chambeies.When a side hydraulic driving chamber tapped into the pressure oil pipe of hydraulic system, then adjacent with it inboard oil pocket was to press the grease chamber during work, and opposite side hydraulic driving chamber connects the return tube of hydraulic system, and adjacent with it inboard oil pocket is the fat absorption chamber.When two hydraulic driving chamber oil-feeds, oil return transposition, the also corresponding transposition with oil suction of oil is pressed in two grease chambeies.
The change that the grease chamber passes in and out oily direction needs to realize by pilot operated directional control valve.Pilot operated directional control valve can be arranged on outside the pump housing, also can be arranged in the pump housing.Pilot operated directional control valve is arranged on the volume that can reduce the pump housing in the pump housing, reduces line loss, guarantee that oil is pressed in two grease chambeies and the oil suction energy is accurate, transposition in time.As shown in Figure 2: spool 11,12 is arranged in the middle spacer sleeve 4 spool 11,12 similar dumbbell shapes.Middle like this spacer sleeve 4 promptly plays the isolation pump housing makes the pump housing be divided into left cylinder 2 and right cylinder body 6, plays the effect of liquid controlled reversing valve body again, and pilot operated directional control valve is built on the middle spacer sleeve 4.
