The purpose of this utility model can reach by the following technical programs:
A kind of cleaning device of lubricating pipe, its design feature is: comprise air compressor, compressed air piping, Pressure gauge, device for drying and filtering, hand-operated valve, adpting flange, explosion plate and check target plate, one end of compressed air piping is connected with air compressor outlet, the other end is connected to device for drying and filtering input port; Pressure gauge is installed on compressed air piping; The input that hand-operated valve input is connected with the delivery outlet of device for drying and filtering, output is connected to pipeline to be cleaned by adpting flange, pipeline output to be cleaned is provided with explosion plate, between pipeline delivery outlet to be cleaned and explosion plate, target plate is installed, forms high pressure seal structure.
The purpose of this utility model can also reach by the following technical programs:
Further, pipe to be cleaned can be connected to explosion plate by seal connector, forms hermetically-sealed construction.
Further, described explosion plate can be fixed on by bolt seal the output of pipeline to be cleaned, explosion in the time that pipe air pressure inside to be cleaned approaches air compressor output pressure.
Further, the area of described check target plate can be less than the area of pipe delivery outlet to be cleaned, indeformable in the time of the explosion of explosion plate.
Further, the intensity of described check target plate can be greater than the intensity of explosion plate.
The beneficial effects of the utility model are:
1, the utility model utilizes airblasting to carry out explosion cleaning to lubricating pipe, produces air detonation phenomenon when airblasting, produces instant impact, reaches the object of impurity and the dirt of quick cleaning pipe interior.Adopt the oil circulation duration in the utility model power plant construction significantly to shorten than common cleaning, oil is increased to 3 grades by 7 grades of NAS grades.Can prevent that power plant from the accident such as bearing bush abrasion and large shaft vibration occurring because of oil-piping cleaning problems occurring between limber up period, significant to the safe operation of unit; Can accelerate the operation progress in power plant.
2, the cleaning device that the utility model relates to forms hermetically-sealed construction, owing to adopting the weak explosion plate of intensity, enter after pipeline to be cleaned at high pressure air, make the moment fragmentation of explosion plate, produce instant impact, realize and treat that cleanser conduit carries out strong dust and foreign matter is removed.There is beneficial effect simple in structure, that cleaning speed is fast and cleannes are high.

Fig. 2 is the structure cutaway view of explosion plate and pipeline to be cleaned installation place.
Fig. 3 is the structural representation that explosion plate is connected with check target plate.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail:
Specific embodiment 1:
With reference to Fig. 1, Fig. 2 and Fig. 3, the lubricating pipe cleaning device that the present embodiment relates to, comprise air compressor 1, compressed air piping 2, Pressure gauge 3, device for drying and filtering 4, hand-operated valve 5, adpting flange 6, explosion plate 8 and check target plate 9, one end of compressed air piping 2 is connected with air compressor 1 outlet, the other end is connected to device for drying and filtering 4 input ports; Pressure gauge 3 is installed on compressed air piping 2; The input that hand-operated valve 5 inputs are connected with the delivery outlet of device for drying and filtering 4, output is connected to pipeline 7 to be cleaned by adpting flange 6, pipeline 7 outputs to be cleaned are provided with explosion plate 8, between pipeline 7 delivery outlets to be cleaned and explosion plate 8, target plate 9 is installed, forms high pressure seal structure.
In the present embodiment:
Pipe 7 to be cleaned is connected to explosion plate 8 by seal connector 10, forms hermetically-sealed construction.Described explosion plate 8 is fixed on the output of pipeline 7 to be cleaned by bolt seal, explosion in the time that pipe 7 air pressure inside to be cleaned approach air compressor 1 output pressure produces instant impact, reaches the object of quick cleaning pipeline.The area of described check target plate 9 is less than the area of pipe 7 delivery outlets to be cleaned, and indeformable in the time of 8 explosion of explosion plate, target plate is used for checking cleannes, after continuous demolition is clean, by checking that the situation on target plate surface judges that whether management is qualified.The intensity of described check target plate 9 is greater than the intensity of explosion plate 8.
