Description
Technical field
The invention mainly relates to the manufacture of reciprocating compressor, installation, technology upgrading transformation, checking maintenance, operation, maintenance skills
Art field is especially widely used in the technology upgrading transformation of chemical company's synthetic ammonia installation compressor, installation with checking maintenance field.
Background technique
Reciprocating compressor using extremely wide, is known as " heart " of chemical industry in chemical industry.General coal chemical industry
The reciprocating compressor of the Ammonia Production device of enterprise is divided into seven grades of compressions, is high pressure section after five sections.Packing seal
Effect is to prevent the medium in cylinder from leaking along piston rod direction, and low pressure stage filler is directly installed in cylinder cylinder seat, high pressure section
Filler is because pressure resistance is more demanding, and the sealing unit of filler is more, and installation dimension is larger, and former capital, which installs one additional outside cylinder cylinder seat, to be filled out
Expect letter body (Fig. 2), to install filler assembly.The stuffing box body of high pressure section uses high-intensitive forge piece, letter because pressure resistance is more demanding
Body thickness is big, and heat dissipation effect is poor, and higher cost.In order to control the overall dimensions of Compressor Group, high pressure section stuffing-box and pressure
Contracting machine slideway scrapes that the gap between food tray is reserved smaller, and the operating space of installation exercise is smaller, and checking maintenance difficulty is big.Because of high pressure section
The thickness reason of stuffing box body, lubricating oil can only form oil circuit, filler one of in this way by the oilhole on each stuffing box
The blocking of box oilhole, gas leakage, setup error all can cause oil circuit obstructed.
The objective requirement of above various unfavorable factors and Production in Chemical Plant device, reciprocating compressor high pressure section filler
It is imperative to upgrade.Chemical company be badly in need of it is a kind of manufacture, installation and checking maintenance it is at low cost, checking maintenance is simple to operation, dress
With the high high pressure section filler device of time saving and energy saving, operational efficiency.
This technology goal of the invention is the heat dissipation effect in order to improve compressor high pressure section filler, increases installation space, reduces
Checking maintenance difficulty improves checking maintenance efficiency, optimization lubricant effect.
Summary of the invention
(1) the technical issues of solving
In view of the deficiencies of the prior art, the present invention provides a kind of no letter body high pressure section filling bodies, solve manufacture, peace
Dress and checking maintenance is at high cost, checking maintenance complicated difficult operates, the problem that assembly takes time and effort, operational efficiency is low.
(2) technical solution
In order to achieve the above object, the present invention is achieved by the following technical programs: a kind of no letter body high pressure section filling machine
Structure, including cylinder block, fastening bolt, locating rod, stuffing box, positioning sleeve and oiling connector, using locating rod to each stuffing box into
The threaded hole of installation locating rod, each stuffing box and big method after chopped-off head stuffing box are reserved in row positioning on chopped-off head stuffing box
The location hole that relative position is processed on orchid makes to realize accurate positioning between stuffing box and cylinder block, large flange, to avoid sealing
The rigging error of original part；
It is positioned between every two stuffing box by positioning sleeve, after filling what a stuffing box, positioning sleeve is installed, then install secondary one
Grade stuffing box, two-stage stuffing box realize Dual positioning by positioning sleeve on the basis of locating rod；
Final stage stuffing box is reserved positioning groove and is positioned with filler large flange boss；
Cylinder block processes bolt bottom outlet, and large flange processes the through-hole with cylinder block bolt bottom outlet position consistency, in gas
It is fastened by bolts between cylinder seat and large flange, realizes the preload force request between filler cover component；
The lubricant passage way of optimization, no letter body high pressure section filling body can pass through note by cancelling stuffing box body, lubricating oil pipe
Oily device is directly injected into stuffing box to check (non-return) valve through the oiling connector on stuffing box, high-efficiency lubricating is realized, than there is letter body filler
More unobstructed by the oilhole oiling of stuffing box axial direction, oil circuit is obstructed caused by being avoided that because of stuffing box assembled in sequence mistake asks
Topic.
Preferably, the length of the locating rod is different with packing seal series, can be true according to the overall thickness of specific stuffing box
It is fixed.
Preferably, the stuffing box outer diameter and positioning sleeve internal diameter are basic hole system tight fit, are executed by tolerance standard H7.
Preferably, the groove and boss are also that basic hole system is fitted close, and are executed by tolerance standard H7.
Preferably, the fastening bolt should select high-intensitive high tension bolt, material 35GrMoA.
(3) beneficial effect
The present invention provides a kind of no letter body high pressure section filling body, have it is following the utility model has the advantages that
(1), this positions each stuffing box using locating rod without letter body high pressure section filling body, each stuffing box it
Between by positioning sleeve position, two-stage stuffing box on the basis of locating rod by positioning sleeve realize Dual positioning.In cylinder block and greatly
By high-intensitive high tension bolt fastening between flange, to eliminate stuffing box body, the heat dissipation effect of filler device has been fully ensured that
Fruit.Compared to than there is the more unobstructed by the oilhole oiling of stuffing box axial direction of letter body filler, it is avoided that because stuffing box sequence fills
The problem for causing oil circuit obstructed with mistake.High efficiency and heat radiation effect and lubricant effect improve sealing effect and the use of filler device
In the service life, the slip of no letter body high pressure section filling body is lower, long service life, so maintenance cost is greatly reduced.Without letter body
The installation of high pressure section filling body, disassembling section are simple.
(2), this is without letter body high pressure section filling body, integral installation after can assembling, and is ready in production run a set of
The a whole set of filler assembled, integral replacing after disassembly piston rod when maintenance.If stuffing box, O-ring can not dismantle piston without damage
Bar, after the nut for removing fastening bolt, move forward large flange, pulls open the seal assembly in the i.e. replaceable stuffing box of stuffing box step by step.
In contrast, filler, the maintenance process of no letter body high pressure section filling body cannot be overhauled by having letter body filler not dismantle piston rod
It is just more efficient, time saving and energy saving.To sum up, no letter body high pressure section filling body is that a kind of slip of energy long-term operation is low, scattered
Thermal effect is good, lubrication is good, installation and repairing is easy to operate, safeguards the low novel stuffing sealing device of aspect, operating cost.
