Abstract
The invention discloses a jet oil collecting device based on a detection experiment of a Commins PT oil injector. The jet oil collecting device comprises a fixing joint, an oil injector sealing part, a joint, an oil pipe, a hydraulic cylinder and a collector. One end of the fixing joint is fixed to a piston rod of the hydraulic cylinder through threaded connection, and the other end of the fixing joint is provided with a stepped counter bored hole in the axial direction. The oil injector sealing part is closely embedded and fixed in the stepped counter bored hole through interference fit. An axial blind hole and a radial blind hole are formed in the oil injector sealing part and communicate with each other. The outlet of the axial blind hole is provided with a sealing conical surface in sealing fit with the oil injector. The outlet of the radial blind hole is in butt joint with a radial though hole in the lateral wall of the fixing joint. One end of the oil pipe is connected with the radial through hole through the joint, and the other end of the oil pipe extends into the collector. The jet oil collecting device has the advantages of being simple in structure, convenient to mount and dismount and the like, and can effectively improve the detection efficiency of the oil injector and reduce damage to the oil injector during detection.

Summary of the invention
The problem that the present invention is intended to solve is, provides a kind of and penetrates oily gathering-device based on comings PT oil sprayer test experience, to realize detecting oil sprayer injected fuel amount, to reduce the object to oil sprayer damage when detecting.
For above-mentioned situation, technical solution provided by the invention is
Penetrate an oily gathering-device based on comings PT oil sprayer test experience, comprise permanent joint, oil sprayer Sealing, joint, oil pipe, oil hydraulic cylinder, trap,
One end of described permanent joint be threaded connection be fixed on described oil hydraulic cylinder piston rod on, the other end of described permanent joint is provided with ladder counterbore vertically, oil sprayer Sealing is closely embedded by interference fit and is fixed in the ladder counterbore of permanent joint, permanent joint and oil sprayer Sealing adopt interference fit, prevent from spraying oil to flow out from its mating face, and when it can being pounded out from permanent joint after sealing part abrasion, change oil sprayer Sealing.The axial blind hole and radial blind holes that are interconnected is provided with in described oil sprayer Sealing, the outlet of described axial blind hole is provided with the sealing cone be sealed and matched with oil sprayer, radial direction through hole on the outlet of described radial blind holes and permanent joint sidewall connects, one end of described oil pipe connects radial direction through hole by joint, and the other end stretches in trap.
Further, described oil sprayer Sealing adopts nylon material, damage to the oil sprayer conical surface when nylon material not only reduces test, and when oil hydraulic cylinder axial force compresses, nylon can produce certain compressive strain, thus improve the sealing effect of oil sprayer Sealing and oil sprayer.
Further, described oil sprayer Sealing outer wall is provided with flat key shape positioning convex vertically, the ladder counterbore inwall of described permanent joint is provided with the positioning groove matched with described positioning convex vertically, and this programme ensures the centering of permanent joint and oil sprayer Sealing oil outlet by the mode that similar flat key is located.
Further, described permanent joint material adopts cemented carbide, ensures the join strength of permanent joint and piston rod.
Further, described joint is quick detach joint, is convenient to install, convenient detection.
Damage to oil sprayer when adopting above-mentioned design effectively can reduce detection, the application of nylon material can strengthen the sealing of cone match, and split-type design can reduce the replacement cost after part injury.Therefore this device has advantages such as structure is simple, easy installation and removal, effectively can improve the detection efficiency of oil sprayer, the injury to oil sprayer when reducing to detect.
