Abstract
The present invention relates to an oil cooling structure for a piston rod of a piston compressor, more specifically a structure for cooling filling of the piston compressor. The present invention belongs to the technical field of cooling devices. The present invention mainly comprises a sealing ring, a latching ring, a filling box and a piston rod. The present invention is characterized in that the tail end of the piston rod is provided with a cooling hole; an oil guide pipe is inserted in the cooling hole, and cooling oil is led into the cooling hole for circulating cooling; the oil guide pipe is tightly pressed on the terminal end of the piston rod through a joint and a shield ring; the filling box and a throttle sleeve are tightly pressed by a press cover and a press plate. The present invention has the advantage of ideal cooling effect; the normal operation of filling can be ensured; the phenomena of cold flow and sealing failure caused by the rise of grinding temperature can be prevented; due to the adoption of the method of oil leading cooling, the service life of the filling can be prolonged, the maintenance work amount can be reduced, and the external leakage amount of gas can be reduced; due to the adoption of the piston rod for oil leading cooling, the machining for the filling is simple, the phenomenon of scale deposit junction in an intermediate water passage for the filling is avoided, and the cleaning work amount is reduced.
Description
Technical field
The present invention relates to a kind of oil cooling structure for piston rod of piston compressor, specifically be used for the cooling of piston compressor filler, belong to the cooling unit technical field.
Background technique
Piston compressor is the universal machine that is widely used in every profession and trade, and wherein, with the compressor of oil content, the non-lubricated compressor that can reach more than half a year or half a year as if its easily damaged parts life-span is not welcome by the every profession and trade user for non-lubricated compressor that is gas.The material that Packings for Non-lubricated Compressor adopts mainly is engineering plastics, as teflon or employing teflon filling carbon fiber, because the tetrafluoroethylene poor thermal conductivity, even add bulking agent to improve its thermal conductivity, still can not be comparable with metal.So temperature is a threat to the working life of seal ring, guarantee the steady running of compressor, the filler under the mesohigh load generally all will be taked cooling method.
Before the present invention makes, in prior art, be used for the cooling of piston compressor filler, normally adopt the type of cooling of filler water flowing.When adopting this structure, cooling water self filler gland 2 lower water inlet A enter stuffing boxes at different levels 4 and through last cover filler, enter next cover filler cooling water cavity after being full of cavity, every cover filler water inlet and outlet up and down repeatedly the circulation back flow out by the top water outlet B.This structure is because the cooling position is far away excessively with the friction surface of filler (comprising seal ring 3 and locking ring 4) from piston rod 1, so cooling effect is undesirable, and the filler processed complex, the easy scaling of filler water channel, and incrustation scale cleans inconvenient.Because cooling effect is bad, causes filler short working life, thereby can directly influence the proper functioning of compressor.
Summary of the invention
The objective of the invention is to overcome above-mentioned deficiency, thereby provide a kind of employing self tightening filler to be adjacent on piston rod, its cooling position and piston rod friction surface are very approaching, cooling effect is very good, also can finely prevent from the mill temperature is raise, and prevent " cold flow " and guarantee sealing, and then can guarantee the oil cooling structure for piston rod of piston compressor of compressor proper functioning.
Main solution of the present invention is achieved in that
The present invention mainly comprises seal ring 4 and locking ring 5, stuffing box 6, piston rod 7, feature is to adopt the tail end at piston rod 7 to be provided with cooling hole, in cooling hole, insert an oil guide pipe 3, feed cold oil circulation cooling, oil guide pipe 3 is pressed on piston rod 7 ends by joint 2 and back-up ring 1, oil guide pipe 3 the other ends are provided with a flange and support, and oil guide pipe 3 and piston rod 7 cooling hole holes are concentric, by gland 9 and pressing plate 10 stuffing box 6 and orifice sleeve 8 are compressed.
3 of piston rod 7 cooling hole and oil guide pipes form annular space among the present invention.
Compared with the prior art the present invention has the following advantages:
1, the long service life of filler: because cooling position and piston rod rubbing surface are very approaching, so cooling effect is very desirable; Because it is exactly overheated influencing the fatal reason of stuffing box packing, good cooling results just can guarantee the proper functioning of filler, prevents grinding the phenomenon generation that temperature raises and causes " cold flow " and seal failure.2, good economy performance: user, particularly large-scale petrochemical enterprise the most important thing is to reduce the unplanned shutdown phase, reduce maintenance load, the user is few in the required spare part quantity of maintenance compressor, prevents that gas leakage from influencing environment etc., and these all can influence economic benefit of enterprises; The piston compressor piston rod adopts logical oil cooling but can prolong the filler life-span, reduces maintenance load, and reduces the leakage quantity that leaks of gas.3, the structure of filler is simpler: because after adopting the logical oil cooling of piston rod but, filler processing will be simply many, and avoid the incrusted phenomenon of water channel in the filler, reduce the workload of cleaning.
Description of drawings
Fig. 1 is a piston rod water flowing cooling structure schematic representation in the prior art.
Fig. 2 is the logical oil cooling structure schematic representation of piston rod of the present invention.
Embodiment
Embodiment during following the present invention incites somebody to action in conjunction with the accompanying drawings is further described:
The present invention mainly is made up of back-up ring 1, joint 2, oil guide pipe 3, filler (seal ring 4 and locking ring 5), stuffing box 6, piston rod 7, orifice sleeve 8, gland 9 and pressing plate 10 etc.
The logical oil cooling structure of the present invention is that the tail end from piston rod 7 bores a cooling deep borehole, inserts an oil guide pipe 3 in cooling deep borehole, feeds cold oil circulation cooling.Oil guide pipe 3 is pressed on piston rod 7 ends by joint 2 and back-up ring 1, and oil guide pipe 3 the other ends are provided with a flange and support, and guarantees oil guide pipe and piston rod 7 deep hole essentially concentrics with this.Filler (comprise seal ring 4 with locking ring 5) is contained in the stuffing box 6, and requires to be provided with many groups can be according to work the time.Filler is adjacent on piston rod 7, and gland 9, pressing plate 10 compress stuffing box 6 and orifice sleeve 8.Cold oil enters the connecting rod oilhole by gear oil pump toward main bearing, enter crosshead pin by connecting rod small end, oil is introduced piston rod 7 cooling deep boreholes and the annular space that cools off between oil guide pipe from crosshead pin by crosshead, and lead away filler (comprising seal ring 4 and locking ring 5) and grind the heat that produces with 7 pairs in piston rod, cold oil is provided with perforate B by oil guide pipe 3 tube walls and enters piston rod 7 dark cooling hole and the annular space of cooling between oil guide pipe, and, pass back in the crankcase again from the middle extend neck of oblique perforate A inflow that piston rod 7 is provided with.
Owing to the fatal reason that influences stuffing box packing is exactly overheated, for guaranteeing the cooling of filler work, prevent from the mill temperature is raise, cause " cold flow " and seal failure, adopt deep hole processing in piston rod, be furnished with oil guide pipe, feed cold oil circulation cooling.Because what adopt is the self tightening filler, therefore filler always is adjacent on piston rod, therefore cool off the position and the piston rod friction surface is very approaching, cooling effect is just very good, also can finely prevent from the mill temperature is raise, and prevent " cold flow " and guarantee sealing, and then guarantee the proper functioning of compressor.Practice is proof also, and this structure can effectively guarantee filler work reliably and with long-term.
