Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technological scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Pressurized machine oil cylinder as shown in Figure 1 to Figure 3, comprise the high low pressure chamber spacer 1 of hyperbaric chamber, low-pressure cavity and connection hyperbaric chamber and low-pressure cavity, sealing place of the piston rod 2 in low-pressure cavity and high low pressure chamber spacer is provided with multiple metallic sheath 3 and polyurethane sealing ring 4, and metallic sheath 3 and polyurethane sealing ring 4 interval are arranged, both the sealing of the piston rod in high low pressure spacer and low-pressure cavity had been strengthened, strengthen again the guidance quality of piston rod, increase the supercharging amplitude of pressurized machine oil cylinder.
The external diameter of one end of metallic sheath 3 is greater than the external diameter of the other end, reduces taking up room of metallic sheath, increases the area of contact of metallic sheath and high low pressure chamber spacer, the sealing of further reinforcement metal cover height pressure spacer and piston rod.
Fig. 3 is the schematic diagram of sealing place of piston rod 2 in low-pressure cavity and high low pressure chamber spacer.
Hyperbaric chamber cylinder body 5 on hyperbaric chamber and sealing place of hyperbaric chamber end cap 6 are provided with taper 7 and Polyurethane seals 8, and taper 7 is positioned at the inner side of Polyurethane seals 8.First utilize taper 7 to be connected with the place to be sealed of hyperbaric chamber end cap 6 by the hyperbaric chamber cylinder body 5 on hyperbaric chamber, then seal with Polyurethane seals 8, strengthen the sealability in hyperbaric chamber, increase the supercharging amplitude of pressurized machine oil cylinder.
Taper 7 is taper copper sheathing.Select taper copper sheathing, add the length of sealed faying face, save material, reduce weight, taper is light; Taper copper sheathing adopts copper material, and thermal conductivity is good, increases the service life.
Metallic sheath 3 is copper sheathing, and intensity is high, wear-resisting, increases the service life.Fig. 2 is the schematic diagram of sealing place of hyperbaric chamber cylinder body and hyperbaric chamber end cap.
Pressurized machine oil cylinder supercharging amplitude in the utility model reaches more than 250Mpa.The working procedure of the pressurized machine oil cylinder in the utility model is, by hyperbaric chamber filler opening injection liquid carburetion or emulsified liquid in hyperbaric chamber cylinder body, in low-pressure cavity, utilize oil hydraulic pump by low pressure rodless cavity hydraulic fluid port injection liquid force feed, piston rod is moved in hyperbaric chamber cylinder body, the increasing pressure produced along with oil hydraulic pump is large, piston rod continues to move in hyperbaric chamber cylinder body, sealing in hyperbaric chamber improves, the guidance quality of piston rod is strengthened, and the sealing of piston rod and high low pressure guide sleeve is strengthened, improve the supercharging amplitude in hyperbaric chamber, the pressure of in low-pressure cavity 10 times is produced in hyperbaric chamber, after reaching the force value of equipment requirement, emulsified liquid in hyperbaric chamber cylinder body or hydraulic oil are injected in the corollary equipment that is connected with hyperbaric chamber cylinder body, complete a supercharging, in low-pressure cavity, utilize oil pump by low pressure rod chamber hydraulic fluid port injection liquid force feed, piston rod is moved in low-pressure cavity cylinder body, causes forming vacuum in hyperbaric chamber, start in hyperbaric chamber cylinder body to suck emulsified liquid or hydraulic oil, when piston gets back to initial position, supercharging terminates.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
