Description

The automatic jet lubrication machine of internal-mixing

The utility model relates to the jet lubrication device, the automatic jet lubrication machine of specifically a kind of internal-mixing.

The milling machine of the exposed gear transmission of using in the industrial production such as thermal power generation at present, metallurgy, building materials, chemical industry all adopts the jet lubrication device to guarantee that exposed gear working under the lubricating condition preferably.Electric elementss such as timer, contactor, control knob have partly been adopted in the control of the lubricating fitting that uses now.Control mode is a directly controlled type.Spray and partly to adopt the external mixture type spray head, its structure as shown in Figure 4 and Figure 5, jet and oil spout is carry out mixed aerosol outside spray head after, to be ejected on the exposed gear.The more old-fashioned lubricating fitting of this class jet lubrication device has very much progress, but yet exists following deficiency:

1, owing to mixed aerosol is carried out in jet and oil spout outside spray head, so the G﹠O mixed aerosol is abundant inadequately, it is cylindric that spray regime is, diameter 100 millimeter, sometimes obviously be linear, the exposed gear of 500 mm wides gets 4 spray heads at least and is lubricated, and does not reach evenly lubricated.

2, because jet width and spray regime are all not ideal enough, so during lubricated large-scale exposed gear, must need to install a lot of spray heads and be lubricated work simultaneously, give and install and maintenance work has brought inconvenience, also increased cost.

3, manual control control is electric, makes control accuracy and automaticity be subjected to certain restriction.

The purpose of this utility model is exactly at above-mentioned deficiency, provides that a kind of jeting effect is good, the automatic jet lubrication machine of the internal-mixing of precise control.

To achieve these goals, the technological scheme that the utility model adopted is: according to fluid mechanics principle, the structure of Renewal Design spray head makes jet and oil spout behind the abundant mixed aerosol, is sector shape by linear nozzle again and is ejected on the exposed gear in spray head; Control section adopts Computer Control Technology, has improved control accuracy and automaticity effectively.Technological points in the scheme is: it comprises that air compressor, oil pump, air filter, air pressure regulator valve, air valve, oil strainer, oil pressure adjusting valve, one-way valve, valve form, it is characterized in that being sealedly connected with on the jet tray internal-mixing spray head, nozzle on the spray head is processed into linear, be provided with the mixing chamber of oil gas mixed aerosol in the spray head, nozzle, nozzle opening and fumarole communicate with mixing chamber.

Described internal-mixing spray head is made up of end cap, base, back of the body cap, and end cap and base connect with positioning spigot, constitutes mixing chamber between end cap inboard and the base top, and linear nozzle is positioned on the end face of end cap, and communicates with mixing chamber.

Described linear nozzle can process one or more, and its width is 0.05-1mm, and the end face at nozzle place is a sphere, also can be cambered surface, plane, concave surface.

After implementing technique scheme, the utlity model has following advantage:

1, oil and gas can access abundant mixed aerosol in the mixing chamber of spray head, and spray regime is fan shape, jet width can reach more than 200 millimeters, and injection is even, and can wash the dirt on the gear teeth, improve the lubrication effect of exposed gear significantly, improved the working life of milling machine.

2, can satisfy the lubricating requirement of all size exposed gear, reduce the spray head usage quantity exponentially, reduce cost, easy to installation and maintenance.

3, precise control is reliable, and is full-automatic, eliminated the hand control Control work.

The utility model is described in further detail below in conjunction with accompanying drawing.

Fig. 1 is the utility model embodiment's a structural principle schematic representation.

Fig. 2 is an internal-mixing injection nozzle structure schematic representation among Fig. 1.

Fig. 3 is the plan view of Fig. 2.

Fig. 4 is present external mixture type injection nozzle structure schematic representation.

Fig. 5 is the plan view of Fig. 4.

As seen from Figure 1, connecting oil circuit and wind path on the jet tray 1 of the automatic jet lubrication machine of internal-mixing.Oil strainer 8, oil pump 7, oil pressure adjusting valve 9, one-way valve 10, valve 11 have been linked in sequence on the oil circuit.Air compressor 6, air filter 5, air pressure regulator valve 4, air valve 3 have been linked in sequence on the gas circuit.By Fig. 2, Fig. 3 as seen, internal-mixing spray head 2 is made up of end cap 2A, back of the body cap 2B, base 3C, and end cap 2A and base 2C connect with positioning spigot, and back of the body cap 2B is fastened together end cap 2A and base 2C.Constitute mixing chamber 2D between end cap 2A inboard and the base 2C top, be processed with one or a plurality of lineal shape nozzle 2E on the end face of end cap 2A, and communicate with mixing chamber 2D.The width of nozzle 2E is 0.06-1mm, and the end face at nozzle 2E place is a sphere, also can be lonely face, plane, concave surface.Oilhole 2F and pore 2G all communicate with mixing chamber 2D.

The working procedure of oil circuit and gas circuit is that computer control is partly controlled during work.After control wiring was connected, each component parts carried out work by control sequence on oil circuit and the wind path.Oil gentle process each self-loop enters in the jet tray 1 with certain purity and rated pressure, and the oilhole 2F on spray head 1, wind hole 2G enter into and carry out mixed aerosol in the mixing chamber 2D again, is sector shape by nozzle 2E and is ejected on the exposed gear and is lubricated.After a lubrication interval was finished, lubricated machine stopped lubricated work automatically, and through behind the certain pause, lubricated machine begins the lubricated work of next cycle again automatically.
