Description
Technical field
The present invention relates to a kind of double disk friction screw press hydraulic pressure reequips mechanism.
Background technology
Double disk friction screw press only has 30% due to transmission efficiency, is the superseded backward product that Chinese government's explicit order is remanufactured
Product, but nowadays still have nearly 30,000 double disk friction screw press to use everyday in various places workshop the reason for be because history.Therefore must
This 30,000 double disk friction screw press must be reequiped to improving the people that its efficiency is significantly saved electric energy and it is fallen behind
Work operation is changed to digitization procedure operation.At present China has started to reequip double disk friction screw press, current repacking side
Method mainly has two：First method of modifying is, with China's ZL200820015356.2 patents, to be reequiped using switched reluctance machines
Abbreviation electricity changes into after electric screw press, but there is the play between its bolt and nut after the repacking of this method during compressor operation
Strong friction consumes big energy and there is phenomenon that its flywheel must invert in slide block return also consumed energy, therefore electricity changes
Power savings only have 30%, second method of modifying China's ZL201220379100.6 patents：Double disk friction screw press liquid
Pressure conversion apparatus patent carries out hydraulic pressure repacking to double disk friction screw press, but only one of which inner casing in the structure of this patent,
Pressure is inadequate during compressor operation, it is impossible to complete technological requirement.
The content of the invention
It is an object of the invention to provide a kind of double disk friction screw press hydraulic pressure repacking mechanism is caused after repacking, and power savings can
Up to 50% and can the producing ratio original bigger pressure of machine be fully able to complete the double disk friction screw press hydraulic pressure modified machine of technological requirement
Structure.
What the content of the invention of the present invention was realized in：
Double disk friction screw press hydraulic pressure reequip mechanism, including fuselage 1, replenishing valve 2, topping up cylinder 3, replenishing valve control oil pipe 4,
Drain line 5, inner casing 6, inner carrier 7, fuselage crossbeam lower flange 8, slide block gland 9 and slide block 10, load in fuselage crossbeam lower flange 8
Outer piston 14；On slide block gland 9 equipped with the symmetrical servo-cylinder 17 of the symmetrical servo briquetting 15, two pieces of two pieces and
The symmetrical servo piston 18 of two pieces；Outer piston 14 is slidably connected with fuselage crossbeam lower flange 8, servo briquetting 15 and slide block pressure
Lid 9 is slidably connected, and servo piston 18 is slidably connected with servo-cylinder 17, and servo-cylinder 17 is fixedly connected with slide block gland 9.
The structure of the present invention does not have violent between screw rod servo-cylinder 17, nut compared with " electricity changes " during compressor operation
Rub, there is no flywheel bow tie, so doubling than " electricity changes " power savings.The present invention structure with
The structure of ZL201220379100.6 patents is compared because of many outer shell and outer pistons 14, inner carrier 7 and outer piston 14 during work
Slide block 10 is pressed to by slide block gland 9 simultaneously, the simple inner carrier of pressure ratio is big, and gross pressure is sufficient for technological requirement.
