Abstract
The utility model relates to a kind of medium seed diesel engine pipelines to pump sealing auxiliary tool, including rubber seal, shaft and screw bolt-type compression bar, it is interference fit between the rubber seal and water pumping hole, the rubber seal is mounted on one end of the shaft, and the other end of the shaft is connected with the screw bolt-type compression bar.Three kinds of parts are brought by screw thread rotation, to play to asymmetric apertures sealing effect.The utility model installation is easy to operate, and energy is very convenient, simply carries out water pumping sealing to medium seed diesel engine pipeline asymmetric apertures.
Description
Technical field
The utility model relates to diesel engine, in particular to when a kind of medium seed diesel engine pipeline asymmetric apertures pump leakage test
The auxiliary tool used.
Background technique
Medium seed diesel engine is one kind of diesel engine, more small in size than low-speed diesel engine in equal-wattage, light-weight.
But medium speed engine increases due to revolving speed height, abrasion；Since cylinder number is more, Parts Breakdown rate is also correspondinglyd increase.Therefore, medium speed engine is confronted
The requirement of amount, precision and performance etc. is higher than common marine low speed diesel engine.Diesel engine is the heart of ship, important
Property is self-evident, and each procedure need to all be executed in strict accordance with the requirement of technique and drawing, be had to pass through after a procedure
The close inspection of professional inspection personnel, just can be carried out next process after meeting the requirements, each fabricated part will be done
To keeping on improving.Pumping test is an indispensable important procedure in process, it can examine entire part casting
Internal leakproofness in the process.It in the R&D process of novel medium seed diesel engine, needs to pump asymmetric apertures, this is it
What preceding medium speed engine pipeline water pumping did not encounter.
Utility model content
The purpose of the utility model is to overcome above-mentioned the deficiencies in the prior art, provide a kind of medium seed diesel engine pipeline water pumping
Auxiliary tool is sealed, to realize the water pumping of asymmetric apertures.
In order to reach above-mentioned purpose of utility model, the technical solution of the utility model is as follows:
A kind of medium seed diesel engine pipeline water pumping sealing auxiliary tool, including rubber seal, shaft and screw bolt-type compression bar, institute
It is interference fit between the rubber seal stated and water pumping hole, which is mounted on one end of the shaft, the shaft
The other end be connected with the screw bolt-type compression bar.
One end of the shaft is equipped with the groove being embedded in for rubber seal.
By the screw-in of screw bolt-type compression bar, shaft is pressed into asymmetric apertures, to make to pump hole sealing.
Compared with prior art, the utility model has the beneficial effects that
(1) applicability is wide, can pump to asymmetric apertures.
(2) it installs, dismantle simply.
(3) can Reusability, it is versatile.
(4) damage to rubber gasket is greatly reduced, use cost is reduced.
Detailed description of the invention
Fig. 1 is the structural schematic diagram that the utility model medium seed diesel engine pipeline pumps sealing auxiliary tool.
Fig. 2 is the usage state diagram that the utility model medium seed diesel engine pipeline pumps sealing auxiliary tool.
Specific embodiment
The utility model is further described in detail with reference to the accompanying drawings and examples, but cannot be used as a limitation this
The protection scope of utility model.
Referring to Fig. 1, Fig. 1 is the structural schematic diagram that the utility model medium seed diesel engine pipeline pumps sealing auxiliary tool,
As shown, a kind of medium seed diesel engine pipeline pumps sealing auxiliary tool, be made of three kinds of parts, rubber seal 1, shaft 2,
Screw bolt-type compression bar 3.It is interference fit between rubber seal 1 and water pumping hole, rubber seal 1 is mounted on shaft 2, by rear
Shaft 2 is pressed into asymmetric apertures by the screw-in of portion's screw bolt-type compression bar 3, to make to pump hole sealing.
The specific installation method of the utility model is as follows:
Step 1, auxiliary tool installation
The auxiliary tool shaft and seal washer are put into the hole 4 for needing to seal in asymmetric apertures, rear portion is then screwed
Compression bar heads into front shaft in hole to make to pump hole sealing.
Step 2, auxiliary tool are removed
Nut is unscrewed, then integrally takes out auxiliary tool.
Experiment proves that leakage test auxiliary tool is pumped with the utility model medium seed diesel engine pipeline asymmetric apertures,
Both the limitation of part water pumping can have been made up, operation is again simple and convenient, has saved cost for enterprise and workshop, and improve effect
Rate.
