Description
Technical field
The invention belongs to shaft seal technical field, more particularly to a kind of novel horizontal pump pump shaft seal structure.
Background technology
Most widely used pump shaft seal structure in the market.Have the following disadvantages：
1. after a period of time is run, because the friction pump shaft of filler can wear, the sealing effectiveness meeting of one long filler of time
It is decreased obviously.
2. needing the compression situation of running check filler, if adjustment compression is elastic, ensure that filler is in most preferably close
Seal effect.
3. if want integral replacing filler, it is necessary to by the water whole emptying in pump, not so water can spray at filler.
Utility model content
To solve above mentioned problem present in prior art and actual conditions, the utility model provides a kind of novel horizontal
Pump pump shaft seal structure, including stuffing box, gland, the stuffing box are used using elongate structure segmentation, a half-loaded material, and one
Half fitted lining set；After journal wear at filler, filler and bushing exchange position installation, can be with the usage time of extending shaft and inspection
Repair the cycle, while ensure sealing effectiveness；
Preferably, self-tightening spring assembly is provided with the gland, the self-tightening spring assembly includes screw rod and self-tightening bullet
Spring, the gland are provided with screwed hole, and the screw rod passes through the screwed hole on gland, end and the follower screw thread of the screw rod
Connection, is provided with self-tightening spring between the screw head and gland, have the function of adjust automatically sealing crush.
Preferably, the outside of the packing seal is provided with header tank, and the header tank is provided with drainpipe.
Preferably, the pump shaft seal structure is additionally provided with air shroud sealing device, the air shroud sealing device bag
Include the air around pump shaft in follower to rewind, and the compressed air line communicated is rewinded with the air.
Preferably, the filler is carbon fibre filler.
The utility model optimizes horizontal pump pump shaft seal structure, using king-size packing seal+air shroud sealing
Structural shape.
1st, stuffing box is used using elongate structure segmentation, a half-loaded material, and half fitted lining set (divides half)；At filler
After journal wear, filler and bushing exchange position installation, can be with the usage time of extending shaft and time between overhauls(TBO), while ensure to seal
Effect.
2nd, filler sealing parts design using point half, motionless pump shaft and miscellaneous part during maintenance, it is possible to easily repair
With replacing filler.
The 3rd, self-tightening spring is set at gland, the function with adjust automatically sealing crush, ensure sealing effectiveness, remove from
Running check filler, while by calculating, can accurately calculate the thrust of gland, sealing effectiveness is in optimal shape
State.
The 4th, header tank is set outside packing seal, collect the water spilt in sealing, and extraction of outwards flowing automatically by drainpipe,
To keep drying in vertical shaft, neatly.
5th, using import carbon fibre filler, to improve sealing effectiveness and service life.
6th, carbon fibre filler has good self-lubricating property, without additional technical water supply.
7th, air shroud seals：Come into operation in maintenance, air shroud is played sealing function by compressed air, will
Water isolation is in pump body, so as to direct integral replacing filler, it is not necessary to as before by the water emptying in pump.
The utility model is sealed using air shroud, reduces maintenance cycle, reduces maintenance time, increases economic benefit.
