Abstract
The utility model relates to a pneumatic booster pump providing superhigh pressure for a hydraulic pump, which belongs to the technical field of booster pump. The pneumatic booster pump is provided with an upper pump body, a lower pump body, a cylinder arranged between the upper pump body and the lower pump body, a high-pressure valve body connected on the lower pump body and an oil inlet and an oil outlet which are arranged on the high-pressure valve body; wherein a piston is arranged in the cylinder, a piston rod with an integral structure is connected on the piston, an oil outlet componentis arranged at the oil inlet, a plunger sealing piece is arranged between the piston rod and the high-pressure valve body, and a gasket is arranged on the outer circumference of the high-pressure valve body connected with the lower pump body. The pneumatic booster pump has the advantages that the abrasion caused by deviation is reduced, the service life is prolonged, and the product quality is improved.
Description
Technical field
The utility model relates to the suction booster technical field, especially a kind of pneumatic suction booster that ultrahigh pressure is provided for oil hydraulic pump.
Background technique
At present, in heavy machinery industries such as shipbuilding, petrochemical industry, electric power, metallurgy, bridge, railway, the main power source that needs big flow more, therefore need provide ultrahigh pressure for oil hydraulic pump, mostly be to realize by the frame type air-driven hydraulic pump, yet pneumatic suction booster is installed on the air-driven hydraulic pump more, produces high pressure.
In product in the past, the piston rod of pneumatic suction booster is divided into two-stage, cylinder and high pressure valve body the inside respectively have one section, the threaded one end separately of examining piston rod interconnects, and piston rod can cause two sections piston rods not in same axle center in processing and installation process like this, and the generation deviation, thereby piston rod can be run into the high pressure valve interior wall when moving up and down, cause wearing and tearing, reduces working life and quality problems occur.Owing to the operation of telling of piston, becoming flexible also can appear in being threaded between the piston rod simultaneously, reduces working life and quality problems occur.
The model utility content
The technical problems to be solved in the utility model is: shortcoming and deficiency in order to solve above-mentioned existence provide a kind of pneumatic suction booster.
The technological scheme that its technical problem that solves the utility model adopts is: a kind ofly have upper pump casing, lower pump body, be arranged at cylinder between upper pump casing and the lower pump body, be connected the high pressure valve body on the lower pump body and be arranged on filler opening and oil outlet on the high pressure valve body, be provided with piston in the cylinder, be connected with the piston rod of integrative-structure on the piston.
Further, in order better to carry out oil suction, the filler opening place is provided with fuel-displaced assembly.
For piston rod is well sealed, be provided with plunger seal between piston rod and the high pressure valve body.
In order to improve tight connection the between high pressure valve body and lower pump body, be provided with packing ring with the external circle of the high pressure valve of lower pump body connecting place.
The utility model removes said structure and also includes the one-way valve that is arranged on filler opening and oil outlet, is arranged on pilot valve device on the valve body, is arranged on down slide valve assembly on the valve body etc., all is needed structure member on the suction booster.
The beneficial effects of the utility model are that pneumatic suction booster of the present utility model because piston rod is structure as a whole, has reduced the wearing and tearing that deviation causes, and has prolonged the life-span of using, and improves the quality of product.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a structural representation of the present utility model.
Among the figure 1, upper pump casing, 2, lower pump body, 3, cylinder, 4, the high pressure valve body, 5, filler opening, 6, oil outlet, 7 pistons, 8, piston rod, 9 fuel-displaced assemblies, 10, plunger seal, 11, packing ring.
Embodiment
In conjunction with the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic representation of simplification, basic structure of the present utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
The pneumatic suction booster of preferred forms as shown in Figure 1, have upper pump casing 1, lower pump body 2, be arranged at cylinder 3 between upper pump casing 1 and the lower pump body 2, be connected the high pressure valve body 4 on the lower pump body 2 and be arranged on filler opening 5 and oil outlet 6 on the high pressure valve body 4, be provided with piston 7 in the cylinder 3, be connected with the piston rod 8 of integrative-structure on the piston 7.
Filler opening 5 places are provided with fuel-displaced assembly 9, are provided with plunger seal 10 between piston rod 8 and the high pressure valve body 4, are provided with packing ring 11 with high pressure valve body 4 outer rings of lower pump body 2 connecting places.
When the utility model is implemented, according to actual conditions, when piston when the next, by slide valve assembly, output pressurized air, piston 7 moves upward, and drives piston rod 8 upwards, sucks hydraulic oil from filler opening 5, at this moment, oil outlet 6 one-way valves are closed condition.When go up on piston 7 arrival tops, touch the pilot valve device, pressurized air is exported by pilot valve, piston 7 begins to move downward, at this moment, in line check valve is a closed condition, and fuel-displaced one-way valve is an open mode, according to mechanics principle, piston 7 drives piston rod 8 and moves downward, squeezed fluid is pressed oil downwards in high pressure valve body 4, thereby produces high pressure, from oil outlet 6 outputs.Below piston 7 arrived once more, when touching slide valve assembly, pressurized air was transferred by slide valve output, and piston 7 begins to move upward, thereby finishes a stroke.Through piston 7 continuous to-and-fro motion, thereby just produce high pressure oil output continuously.
With above-mentioned foundation desirable embodiment of the present utility model is enlightenment, and by above-mentioned description, the related work personnel can carry out various change and modification fully in the scope that does not depart from this model utility technological thought.The technical scope of this model utility is not limited to the content on the specification, must determine its technical scope according to the claim scope.
