The mounting and dismounting method of the thrust disc ［ 0022 ］ the invention allows for, it is characterized in that: when dismounting thrust disc, its technical process is contrary during with installed thrust dish, first retainer ring leading portion is screwed on axle, until touch the end surface that its front end touches thrust disc.With high-pressure pump pressurization, until thrust hub is unclamped.
The mounting or dismounting tools of thrust disc of the present invention and mounting and dismounting method, during thrust disc, not only can save heavy manual labor in mounting or dismounting, and can make thrust disc mounting or dismounting safety, carry out stably, there is good technique effect.
Accompanying drawing explanation
Fig. 1 is the front view of the mounting or dismounting tools of thrust disc of the present invention; Fig. 2 is the work schematic diagram of thrust disc mounting and dismounting method of the present invention.In above-mentioned each figure, 1 slip ring; 2 retainer rings; 3O type ring; 4 handles; 5 packing rings.
The specific embodiment
Below in conjunction with accompanying drawing, the mounting or dismounting tools of thrust disc of the present invention and mounting and dismounting method are done further to supplement and explanation.
As shown in Figure 1, adopt normal carbon steel forgings, processing slip ring 1, slip ring is a hollow cylinder, and cylinder inside is divided into two sections of front and back, and the internal diameter of leading portion is less than back segment.With carbon steel forging process, go out retainer ring 2 again, retainer ring adopts the two-part structure of hollow, the external diameter of its leading portion is less than back segment, match with the internal diameter of two sections, slip ring respectively, between the front end of retainer ring and slip ring, be provided with packing ring 5, retainer ring by former and later two O type rings 3 with the close fit of slip ring front and rear portions to avoid the leakage of low-lift pump oil, O type ring adopts fluorubber to make.The inner car of the front end of retainer ring has internal thread, and it can match with the external screw thread of the main shaft of blade fluid machinery.Retainer ring inside is drilled with the hole pipe for the treatment of screw thread matching with high-pressure pump joint; Its bottom, the rear end of retainer ring is drilled with two threaded hole pipes, is respectively used to be connected with handle 4 with low-lift pump joint.
As shown in Figure 2, after each parts of the mounting or dismounting tools of thrust disc being manufactured and assemble successfully by above-mentioned technique, when adopting its installed thrust dish, first thrust disc adjusting pad and thrust disc are enclosed within on the main shaft of blade fluid machinery, then thrust disc mounting or dismounting tools is shifted near to main shaft; Then slip ring is alignd with spindle nose, with spiral, it is connected with main shaft, until the outside of thrust disc and the packing ring of mounting or dismounting tools contact; Install, connect high and low pressure oil pump device system; Now, first with high-pressure pump pressurization, then, with low-lift pump pressurization, to thrust disc applied thrust, two pumps replace supercharging, until shift thrust disc onto tram; After thrust disc installs, first stop high-pressure pump, could allow low-lift pump pressure release after at least will waiting 3～5; Finally turn on being threaded between retainer ring and main shaft, unload mounting or dismounting tools.
If need to adopt its dismounting during thrust disc, also as shown in Figure 2, but its technical process is contrary during with installed thrust dish, first the mounting or dismounting tools of thrust disc is screwed on axle, until touch the end surface that its front end touches thrust disc.With high-pressure pump pressurization, until thrust hub is unclamped.
Enumerate again the specification that some embodiment illustrate thrust disc mounting or dismounting tools below, but these specifications can not limit structure of the present invention and the scope of application.
Slip ring outer through being 170 millimeters; 95 millimeters of leading portion internal diameters, 130 millimeters of back segment internal diameters; 95 millimeters of retainer ring leading portion external diameters, 56 millimeters of internal diameters; , leading portion screw thread is M56,130 millimeters of retainer ring back segment external diameters, 70 millimeters of internal diameters; 95 millimeters of washer outer diameter, 58 millimeters of internal diameters, thickness is 5 millimeters.
Slip ring outer through being 190 millimeters; 115 millimeters of leading portion internal diameters, 150 millimeters of back segment internal diameters; 115 millimeters of retainer ring leading portion external diameters, 64 millimeters of internal diameters, leading portion screw thread is M64; 150 millimeters of retainer ring back segment external diameters; 100 millimeters of internal diameters; 115 millimeters of washer outer diameter, 70 millimeters of internal diameters, thickness is 5 millimeters.
［ 0034 ］ embodiment 3 is for the mounting or dismounting tools of 100～110 millimeters of spindle nose thrust discs of diameter
Slip ring outer through being 210 millimeters; 135 millimeters of leading portion internal diameters, 170 millimeters of back segment internal diameters; 135 millimeters of retainer ring leading portion external diameters, 95 millimeters of internal diameters,, leading portion screw thread is M72; 170 millimeters of retainer ring back segment external diameters, back segment is interior through 105 millimeters; 135 millimeters of washer outer diameter, 95 millimeters of internal diameters, thickness is 5 millimeters.
Because blade fluid machinery is conventionally to very heavy,, employment frock is torn very difficulty open, not only taken a lot of work, but also effort, and easily make mechanical spindle deformation, or because decentraction between blade fluid machinery and engine exists certain stress, these all can make compressor operating undesired.Adopt mounting or dismounting tools of the present invention and mounting and dismounting method, just can effectively address the above problem, not only can save the heavy manual labor of workman, and can make thrust disc mounting or dismounting safety, carry out stably, there is good technique effect.
