Abstract
The present invention is a kind of hydrodynamic lubrication fat pump: be applicable to various hydraulic construction machine, is changed without grease used when grease continues with former room temperature under cold temperature.Two-piston oil cylinder volume in pump, at the same time with same flow, with pressure input hydraulic pressure pump pressure oil to two-piston oil cylinder make two-piston run to terminal produce big piston than valve piston extend the time arrive, grease absorbing port switch is fast, plunger has the liposuction of prolongation time and pressure fat in plunger cavity, controlled electromagnetic valve switch by electronic circulation time switch, two pistons correspondence simultaneously is done repeatedly liposuction continuously or pressure fat motion.Hydrodynamic lubrication fat pump is placed in container on grease face, being arranged on by uniform machinery hydraulic pump makes grease heat up again, electronic circulation time switch and electromagnetic valve are installed at uniform machinery relatively low temperature, with high-pressure hose correspondence connection electromagnetic valve and the hydrodynamic lubrication each oil connection of fat pump, with the grease gun meeting the manual electrical switch of high-pressure hose connection that on uniform machinery, the longest oil site is grown accordingly.
Description
Technical field:
The invention belongs to field of tool, it is adaptable to various hydraulic construction machines.Add under particularly suitable cold temperature
Note grease.
Background technology:
Use the grease pump of lubrication on existing hydraulic construction machine, have manually and foot-propelled, steam-operating and
Electronic.Because of the most once contain grease amount little, foot-propelled grease pump in-convenience in use, oilhydraulic engineering
Machinery majority does not has air force, is furnished with driven lubricating grease pump power again little.And grease absorbing port does not has bottom valve, inhale
Fat mouth is located at liposuction chamber 1/3rd more, just produces liposuction more difficult.Produce close at low temperatures because of grease
Degree increase is more difficult to inspiration grease.So the grease pump being now furnished with can not meet and work under cold temperature
Hydraulic construction machine lubricates.The grease pump shop instructions of existing market supply hydraulic construction machine are the most dated
For below 9 DEG C, relatively low trade mark grease please be change.Current research invention is exactly that solution can meet oilhydraulic engineering
Machinery is not necessary to change grease under cold temperature, and is continuing with same trade mark grease used during former room temperature.
Summary of the invention:
The present invention seeks to design a kind of hydrodynamic lubrication fat pump with bottom valve.Remain at low temperatures quickly note
Enter the grease using the same trade mark under former room temperature.
The technical scheme is that and be achieved in that: with two unequal hydraulic jacks of volume size, greatly
The plunger of piston driving grease pump in hydraulic jack, plunger inhales grease in plunger cavity and high extrusion lubricates
Fat, bottom valve switch in piston driving plunger liposuction chamber in little hydraulic jack.Hydraulic oil is through two oil cylinder inputs and returns
Directly through equal in 4 the hydraulic jack joints flowed out.Spring and steel ball, low pressure is had in high pressure grease outlet switch
Electronic circulation time switch, electromagnetic valve switch, bedplate, dust cap, balance and stability sleeve pipe, band high pressure is soft
The grease gun of pipe manual control electrical switch, contains the container of grease.
The hydraulic jack that said two size volume does not waits, directly real through equal just energy in hydraulic jack junction block
The most same flow. same to hydraulic pressure, it is simultaneously entered to two hydraulic jacks, in little hydraulic jack, piston is than big hydraulic pressure
In oil cylinder, piston arrives first terminal, and two pistons have time difference to have time delay to terminal.Utilize little volume hydraulic pressure
The piston driving bottom valve switch of oil cylinder is first reached home and is fully opened grease absorbing port, piston in the biggest hydraulic jack
Drive grease plunger by continuing liposuction during time delay, add suction grease mouth and manufacture and design flue,
Spring and steel ball in high pressure grease outlet are closed high pressure grease outlet by plunger suction spring elongation steel ball, it is achieved inhale
Fat is smooth.The two hydraulic jack controls electromagnetic valve switch by Low-voltage Electronic circulation time switch, makes two
The piston of hydraulic jack reverse direction operation simultaneously, bottom valve switch in piston driving plunger liposuction chamber in little hydraulic jack
Closing rapidly grease absorbing port, in the biggest hydraulic jack, piston promotes sliding cylinder extrusion grease, high-pressure grease pressure
Contracting spring opens high pressure grease outlet with backing down steel ball.During time delay, high pressure goes out grease to manual electrical switch
Grease gun.The adjusted grease of inhaling well of Low-voltage Electronic circulation time switch is controlled with high-pressure grease interval time
Electromagnetic valve switch processed, makes piston in the two hydraulic jack move the most continuously, constantly that high-pressure grease is defeated
Enter the grease gun of manual electrical switch.
Described in cold climates without changing grease trade mark standard, and make needed for being rapidly injected machine sections
Grease.It is that above-mentioned hydrodynamic lubrication fat pump is connected with the equal-sized bedplate of container, is placed in
Fill in grease container above grease, be enclosed within profit by the balance and stability sleeve pipe correspondence respectively on dust cap
On grease pump and grease container each position connects fixing, and the grease gun of manual electrical switch and conveying high-pressure
The high-pressure hose of grease is all installed in uniform machinery hydraulic pump side, produces temperature by hydraulic pump works
Raise grease temperature.And electromagnetic valve switch and Low-voltage Electronic circulation time switch are not suitable for temperature height, can
It is arranged on uniform machinery temperature than relatively low place, with high-pressure hose correspondence connection electromagnetic valve and hydrodynamic lubrication fat pump
Each oil connection.With meeting the high-pressure hose connection grease pump that on uniform machinery, the longest oil site is grown accordingly
Grease outlet and the grease gun of manual electrical switch.So grease temperature raises hydrodynamic lubrication fat pump and grease
Container is motionless, only the grease gun of the manual electrical switch of mobile band high-pressure hose, just realizes under cold climate not
Change the grease trade mark, note on same construction machine at each lubrication smoothly.
