Description
Technical field
The utility model relates to a kind of natural gas filling station compressor, cooling unit in especially a kind of filler of compressor.
Background technique
Filler mainly is the element in sealing cylinder and piston rod gap, it can stop gas from cylinder to the fuselage internal leakage.Filler is again an easily damaged parts simultaneously, can lose efficacy like cooling imperfection filler, will cause a large amount of leakages; Reduce productivity; When poisonous or flammable explosive gas takes place to leak, just pollute the environment or cause explosive accident, the quality of filler cooling directly has influence on the proper functioning of compressor.In traditional filler cooling; Cold oil is imported and exported and imported and exported the port size diameter with stuffing box because of the influence that receives the stuffing box size is 5mm; This is just higher to cylinder block and stuffing box requirement on machining accuracy; And wayward when assembling, oil cooling but passage is less than normal, in use finds the cooling imperfection.Along with the development need of natural gas compressor, research and develop and a kind ofly can adapt to new structure natural gas compressor, that processing cost is low, easy to operate and become extremely urgent task.
The model utility content
The purpose of the utility model is exactly in order to solve conventional filler box machining accuracy height, inconvenient operation, can not to adapt to the technical problem that the natural gas compressor filler fully cools off, and cooling unit in a kind of filler is provided.
The utility model solves the technological scheme that its technical problem adopted:
Cooling unit in the filler; Comprise flange, stuffing box, seal ring and the connecting body that is connected with cylinder; It is characterized in that: have the ladder hole of axial setting on the connecting body, connecting body axially is provided with cooling jacket, is provided with one group of stuffing box in the cooling jacket; On stuffing box and connecting body, be provided with the seal ring that is arranged in order; On cooling jacket is axial, be provided with flange, flange is provided with water inlet and osculum, on the outer circumferential face of one group of stuffing box, is provided with two cooling water channels and is communicated with water inlet and osculum respectively; Article two, cooling water channel runs through the end face of stuffing box to connecting body vertically successively, is provided with spill Huan Tai at the end face of connecting body and is connected with two cooling water channels.
Traditional oil circuit processed on stuffing box change stuffing box into and add cooling jacket and remove to cool off stuffing box through cooling water and cooled off fully to reach filler; After improving, improved circulation passage greatly; Filler can be cooled off fully, improved the working life of filler.
On the basis of above-mentioned main technical schemes, can increase following further perfect technological scheme:
Described two cooling water channels are provided with along the axially vertical of one group of stuffing box.
Described two cooling water channels are symmetrical set with axis at the stuffing box outer circumferential face.
The described connecting body end that is connected with cooling jacket is step-like end.
Described and cooling jacket flange connecting end is step-like end.
The beneficial effect of the utility model is after improving, to have improved circulation passage greatly, and filler can be cooled off fully, has improved the working life of filler, and execute-in-place is simple, need not reprocess into oil drain out on the cylinder, and reliability is high.
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
