Embodiment
Below in conjunction with accompanying drawing and through specific embodiment the utility model is done further to detail, following examples are descriptive, are not determinate, can not limit the protection domain of the utility model with this.
Present embodiment is lubricated with φ 180mm tandem rolling seamless steel pipe hot-rolling production line engineering restraint tooth bar to be that example is described.
A kind of seamless steel pipe hot-rolling production line tooth bar sprays the grease lubrication system; Referring to Fig. 1; Comprise grease pail 19, high-pressure pneumatic plunger pump 18, source of compressed air 16, PLC programmable device 1, the folded formula distributing valve 4 of lubricating grease, the folded formula distributing valve 13 of gas and atomizing gun 8, grease pail is transported to the folded formula distributing valve of lubricating grease through the high-pressure pneumatic plunger pump of pegging graft within it through pipeline, and the folded formula distributing valve of lubricating grease connects atomizing gun through lubricating grease electropneumatic valve 6; One electric heating thermostat 7 also is installed on the pipeline of atomizing gun front end;,, improve the jet atomization effect of atomizing gun so that the temperature of the lubricating grease that sends is controlled in 75 ± 2 ℃ of scopes.The high-pressure pneumatic plunger pump is driven through compressed air valve 15 by source of compressed air; On the pipeline before high-pressure pneumatic plunger pump and the compressed air valve, a reduction valve 17 is installed also; To adjust compressed-air actuated pressure between 0.4-0.6Mpa; The setting pressure of the lubricating grease of control high-pressure pneumatic plunger pump outlet realizes extracting the lubricating grease in the grease pail out the conveying of boosting, and the outlet pressure of high-pressure pneumatic plunger pump is 50: 1 with the compressed air pressure ratio.
Also through the folded formula distributing valve of pipeline connection gas, the folded formula distributing valve of this gas can be set the pressurized air of different pressures to source of compressed air through compressed air valve.The folded formula distributing valve of gas is communicated with the spray fat switch and the nozzle of atomizing gun respectively through switch electropneumatic valve 9 and spraying electropneumatic valve 10; On the tracheae of the folded formula distributing valve front end of gas, a reduction valve 14 is installed also, the effect of this reduction valve is same as the reduction valve that the high-pressure pneumatic plunger pump is installed.
The switch electropneumatic valve of the lubricating grease electropneumatic valve of compressed air valve, the folded formula distributing valve of lubricating grease, the folded formula distributing valve of gas and spraying electropneumatic valve are controlled by the PLC programmable device.In addition, switch pressure opening and closing valve 12 and the atomisation pressure switch valve 11 installed of the pressure opening and closing valve 2 installed of high-pressure pneumatic plunger pump rear end pipeline, the pressure opening and closing valve 5 of the folded formula distributing valve of lubricating grease, the folded formula distributing valve two-way tracheae of gas also controlled by the PLC programmable device.
The fluctuation of the lubricating grease constant-voltage system pressure that delayed startup caused of air piston pump also is equipped with an accumulator 3 when starting for solving atomizing gun on the pipeline of high-pressure pneumatic plunger pump rear end, to realize the stable of pressure.
Because the viscosity and the temperature of lubricating grease have sizable relation, temperature high remperature grease viscosity descends, and viscosity is more little, and atomizing effect is good more.For this reason, the lubricating grease pipeline of spray gun front end is provided with an electric heating constant temperature device 7, and the temperature of lubricating grease is controlled in 75 ± 2 ℃ of scopes, improves the jet atomization effect of spray gun.
Parts that the utility model is not described in detail and device are existing technology.
The method that native system sprays fat is adopted in narration below; Referring to Fig. 2; The control tooth roller box is upper and lower respectively to have two actuation gears 20, the two-sided tooth bar 21 front and back synchronous operations therebetween of these two gear drive, and these tooth bar both sides are provided with roller and are supported on (existing technology on the guide rail; Do not illustrate), the lubricated employing atomizing gun spray lubrication of four gears and tooth bar face.
Atomizing gun position: apart from about actuation gear 20 flank of tooth 200mm;
Flank of tooth oil slick thickness: 8-10 μ m (5-6 by roughness doubly calculates);
Tooth bar each run oil film consumes thickness: 1-3 μ m.
The working principle of the utility model is:
Start compressed air valve; Constant voltage (0.4-0.6MPa) output pressurized air through reduction valve; Drive high-pressure pneumatic plunger pump (outlet pressure is 50: 1 with the compressed air pressure ratio) and will be stored in lubricating grease extraction in the bucket; Automatically control through the PLC programmable device through pressure transducer, realize that the constant voltage that the lubricating grease transporting system is set (generally is set at 15～25MPa) supplies.When pressure reached setup parameter, high-pressure pneumatic plunger pump pump trip was kept pressure constant state, realized the lubricating grease supplied with constant voltage of spray gun.
Pressurized air is through the folded formula distributing valve of the gas behind the reduction valve; Each branch road pressurized air of the certain pressure that produces mixes with the quantitative lubricating fat of spray gun; Spray by the spray gun high pressure then; Lubricating grease is dispersed into the droplet about 50 μ m by air-flow, and lubricating grease is realized atomizing, realizes the effect that gear surface evenly covers.Whenever, carry oil mass manual modulation valve and tolerance manual modulation valve to spray gun respectively, to realize the control of atomizing and lubricating grease emitted dose.
Spray gun is to adopt pressurized air to lubricating grease processings that atomize, and lubricating grease can be covered uniformly need the gear surface that lubricates.The startup of spray gun, stop signal being provided by the milling train computer; Through the PLC of system programmable device control, realize the electropneumatic valve of supplying lubricating grease electrically-controlled valve, control spray gun oil circuit threshold switch and the spraying electropneumatic valve that spray gun is used for gas atomization startup, stop.Wherein the injection cycle of spray gun can be set through the PLC programmable device, and every road lubricating grease emitted dose is set by the folded formula distributing valve of lubricating grease in advance, realizes native system unmanned, operation automatically.
The supply of spray gun lubricating grease adopts the folded formula distributing valve of lubricating grease to distribute supply, thereby can realize multiple spot atomizing requirement.The high-pressure pneumatic plunger pump can not in time start (delayed startup) when starting suddenly for solving spray gun; The huge fluctuation of the lubricating grease constant-voltage system pressure that causes; In pipeline, be added with accumulator; Realize that pressure slowly fluctuates, the scope of pressure surge in the air piston pump delayed startup process is dwindled, reach the stable effect of system pressure.
System's characteristics explanation:
Air piston pump is carried output quantity: 8000g/min (adjustable), and atomizing gun adopts the import atomizing gun, and spray smectic attitude is stable.The oil pump capacity of each atomizing gun can be carried out manual tune according to the actual use condition of equipment.Atomizing gun is the method that adopts the pressurized air atomizing, to the lubricating grease processing that atomizes, makes lubricating grease can cover gear surface uniformly.When the atomizing gun distance was lubricated face 200mm, the spraying swath width was 250mm.Cover for satisfying face of gear 370mm width requirement, each lubricating point configuration 2 is used atomizing gun side by side, to reach the face of gear width requirement of covering 370mm.
Automatic, manual two kinds of operator schemes that native system is divided into, man-machine dialog interface adopts touch screen.
The branch roads system of each oil circuit is monitored constantly, if any branch road pressure is undesired, reports to the police immediately.
