Detailed description of the invention
Below in conjunction with specific embodiment, the invention will be further described, and the illustrative examples invented at this and explanation are for explaining the present invention, but not as a limitation of the invention.
As shown in Figure 1, Figure 2, Figure 3 shows, a kind of double mode self adaptation hand grease gun, including oil storage barrel 1, pitch brace 2 and draw-bar seat 9, hand rest 3 and handle 4, hand piston 5, connecting rod 6, the pump housing 8 and nozzle 7, oil storage barrel piston 11 and spring 12.Oil storage barrel 1 is arranged on the pump housing 8 side；Described pitch brace 2 is coaxially slidably mounted in oil storage barrel 1, and pitch brace 2 one end is coaxially installed with draw-bar seat 9, and pitch brace 2 other end is provided with baffle ring, is provided with hand rest 3 outside baffle ring.Oil storage barrel piston 11 is coaxially mounted on pitch brace 2, and is positioned at draw-bar seat 9 rear portion.Spring 12 is arranged on pitch brace 2, and spring 12 one end compresses oil storage barrel piston 11, and spring 12 other end is pressed on the baffle ring of pitch brace.Hand piston 5 is arranged on the pump housing 8 top, and communicates with the pump housing 8 inside.Connecting rod 6 one end is hingedly mounted on the pump housing 8 side, the hinged handle 4 that is provided with of connecting rod 6 other end, and be hinged in the middle part of handle 4 installation with hand piston 5 top.Nozzle 7 is arranged on the pump housing 8 side, and communicates with the pump housing 8 inside.On the excircle that oil storage barrel piston 11 contacts with oil storage barrel 1, O-ring seals 10 is installed.
The hydraulic system of pump body is as described below: form two chambers, respectively big chamber, top and bottom loculus between hand piston 5 and the pump housing 8.Big chamber, top is connected with oil storage barrel 1 by pipeline, installs inlet one-way valve 1 in the middle of pipeline, and oil circuit direction is from the big chamber of oil storage barrel 1 to top；Described bottom loculus is connected with oil storage barrel 1 by pipeline, installation inlet one-way valve 2 14 in the middle of pipeline, oil circuit direction from oil storage barrel 1 to bottom loculus；Big chamber, described top is connected with nozzle 7 by pipeline, pipeline centre installation outlet check valve 1, oil circuit direction from top big chamber to nozzle 7.Bottom loculus is connected with nozzle 7 by pipeline, pipeline centre installation outlet check valve 2 17, and oil circuit direction is from bottom loculus to nozzle 7.Nozzle 7 is connected by pipeline with oil storage barrel 1, installs high-pressure overflow valve 16 in the middle of pipeline, after reaching to set pressure, is connected with oil storage barrel 1 at nozzle 7.Being provided with hydraulicdirectional control valve 15 at nozzle 7 and between oil storage barrel 1, after reaching to set pressure, the bottom loculus of hand piston 5 is connected by hydraulicdirectional control valve 15 with oil storage barrel 1.Low pressure relief valve 19 is arranged on the pipeline between the bottom loculus of hand piston 5 and Outlet check valves 1, and after reaching to set pressure, the big chamber, bottom of hand piston 5 is connected with oil storage barrel 1.
The operation principle of the present invention is: before using grease gun, first oil storage barrel 1 is backed out from the pump housing 8, then pulls back hand rest 3, put into from front end and install to oil storage barrel 1 after butter, the pump housing 8, finally hand rest 3 be back into bottom again；Present invention work can be divided into low pressure and mass flow the most oil-filled and the oil-filled both of which of small flow high pressure, and can be automatically performed conversion；When work system need low pressure quick oil-filled time, upwards carrying handle 4 makes hand piston 5 rise, there is vacuum in hand piston 5 bottom loculus and big portion loculus, under pressure that now butter is applied by oil storage barrel piston 11 by spring 12 and the vacuum dual function that hand piston 5 causes, respectively enter the big chamber of hand piston 5 bottom loculus and top through inlet one-way valve 1 and 2 14 points of two-way of inlet one-way valve and complete oil-absorbing process；Pressing handle 4, due to inlet one-way valve 1 and the unidirectional logical oil characteristic of inlet one-way valve 2 14, butter will not return in oil storage barrel 1 in former road, during due to low pressure, low pressure relief valve 19 will not be opened, pilot operated directional control valve 15 is closed under the action of the spring, butter enters at nozzle 7 through Outlet check valves 2 17 and Outlet check valves 1, pressure at nozzle 7, before i.e. system pressure is not up to the pressure that high-pressure overflow valve 16 sets, high-pressure overflow valve 16 is closed, and now butter returns in oil storage barrel 1 without going past high-pressure overflow valve 16；During buying oil, after system pressure is increased to the operating pressure of pilot operated directional control valve 15, pilot operated directional control valve 15 action, hand piston 5 bottom loculus is connected with oil storage barrel 1, now, during pressing handle 4, hand piston 5 bottom loculus will be no longer to system fuel feeding, and big chamber, hand piston 5 top to system fuel feeding, thus completes the low pressure and mass flow conversion to high-pressure low-flow still through Outlet check valves 1.
The effect of mesohigh overflow valve 16 of the present invention: set up grease gun skyer oil pressure, protection grease gun will not damage because of superpressure.Mesolow overflow valve 19 of the present invention acts on: set the maximum pressure in big chamber, grease gun hand piston 5 lower end, and when preventing pilot operated directional control valve 15 from the most completely commutating or be stuck, the big cavity pressure in hand piston bottom rises too high and causes and armrest pressure cannot play oil condition generation.
