Description

The hydraulic pressure grease compressor

The utility model relates to the annotate oil gun of lubricant grease of a kind of component in machinery, particularly a kind of hydraulic pressure grease compressor.

At present, in equipment, annotate lubricating oil filling fat, be to adopt direct-filling type hand oil gun mostly, this oil gun is directly to push grease by manpower, the people will with the hands not stop during operation presses handle, because resistance is big, and very time-consuming in the operating process, effort, and in extrusion process, very easily entering air in the gun barrel, the grease of output is discontinuous.This grease compressor so can't measure the grease that adds, is not that deficiency is exactly excessive owing to be to judge volume read-out with people's sensation, as oil the time because pressing of not stopping of both hands, grease very easily spills, contaminated equipment.Because the grease pressure of oil nozzle output is less, can't refuel simultaneously to the component in the equipment with pressure.

The purpose of this utility model is in order to overcome above-mentioned deficiency, a kind of hydraulic pressure grease compressor to be provided.

The technical solution of the utility model is, mainly partly form by the gun barrel part and the small of the stock, be provided with piston in the gun barrel, piston will be separated into two chambeies in the gun barrel, the front end of piston is the grease chamber, and the rear end of piston is an active chamber, and grease is provided with spring in the chamber, be filled with stand-by grease during work in the grease chamber, circuit hydraulic oil in being filled with in the active chamber; Piston is provided with pull bar, and an end of pull bar stretches out outside the rear end of gun barrel; Be provided with trigger before the small of the stock, the small of the stock has the oil storing bottle of storing hydraulic oil, move behind one end of trigger and be fixed on the small of the stock on hand, be provided with the hydraulic circuit that constitutes by plunger pump and hydraulic element in the small of the stock, the middle-end of trigger links to each other with the plunger of plunger pump, and trigger promotes the plunger pump motion, by hydraulic circuit hydraulic oil is compressed into the gun barrel active chamber, promote piston advances forward, thereby compression grease chamber extrudes grease.

In hydraulic circuit, the oil outlet of plunger pump connects the one-way valve of two positive and negative settings respectively, oil outlet along logical one-way valve communicates with the gun barrel active chamber, the oil outlet of active chamber and suitable logical one-way valve is connected ball valve more respectively, and the other end of ball valve communicates and communicates with oil storing bottle simultaneously with the filler opening of contrary logical one-way valve.

Pull bar is provided with scale, with the storage of grease in the indication gun barrel, and can the grease that be injected be measured.

The utility model has the advantages that, rational in infrastructure, easy to operate, owing to be provided with oil hydraulic circuit, very time saving and energy saving during operation, the grease delivery pressure is big, and continuously, steadily, reliable, applicable various in, base pressure equipment lubricated, simultaneously also can to as the grease annotated accurately measure.

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is a hydraulic circuit diagram of the present utility model.

Providing the utility model embodiment below also is further described in conjunction with the accompanying drawings:

The utility model mainly partly is made up of the gun barrel part and the small of the stock.Be provided with piston 4 in the gun barrel 3, piston 4 will be separated into two chambeies in the gun barrel 3, and the front end of seat piston 4 is the grease chamber, and the rear end that is positioned at piston 4 is the hydraulic working oil chamber, is provided with spring 2 in the grease chamber.Be filled with grease to be annotated during work in the grease chamber, circuit hydraulic oil in being filled with in the active chamber.For the ease of installing, the front end and back end of gun barrel 3 is designed to removable oil nozzle end cap 1 and rear end cover 7 respectively, and oil nozzle end cap 1 and rear end cover 7 and gun barrel 3 are for being threaded.Piston 4 is provided with O-ring seal 5 and dovetail seal ring 6.Also be provided with pull bar 8 on the piston 4, an end of pull bar 8 is fixed on the piston 4 by screw thread, and the other end of pull bar 8 becomes bending handle and 1 Shen to go out outside the gun tube rear end lid 7, and rear end cover 7 is provided with seal ring 9.But the motion of pull bar 8 auxiliary pistons 4 in the time of need adding, can spur pull bar 8 again after grease uses up in the gun barrel 3, to assist the elastic force of spring 2, promotes the piston backspace, sucks grease by the oil nozzle on the oil nozzle end cap 7.Also be provided with scale on the pull bar 8, because pull bar 8 is fixed on the piston 4 and with piston 4 motions, its scale can indicate the storage volume of grease fat in the gun barrel 3, and according to stroke the grease that injects is measured.

Gun barrel 3 has the small of the stock 15, and the small of the stock 15 is made for nonmetallic material, and fixes with gun barrel 3.The small of the stock 15 is provided with trigger 18, and the upper end activity of trigger 18 is fixed on the small of the stock 15, pulls before and after the available hand.The bottom of the small of the stock 15 is provided with the oil storing bottle 16 of storing hydraulic oil, and oil storing bottle 16 links by the screw thread and the small of the stock 15.Be provided with the hydraulic circuit of forming by plunger pump 19, ball valve 12, one-

way valve

13,14 in the small of the stock 15, and constitute oil hydraulic circuit with the active chamber and the oil storing bottle of gun barrel 3.The middle-end of trigger 18 links to each other with the plunger of plunger pump 19.During work, with hand trigger action 18, trigger 18 promotes plunger pumps 19 motions, by oil hydraulic circuit hydraulic oil is compressed into the active chamber of gun barrel 3, promote piston 4 and travel forward, thereby compression grease chamber extrudes grease from oil nozzle.Be provided with spring 20 between plunger pump 19 and the trigger 18, so that trigger 18 resets.
