The present invention has the characteristics of simple method, compact structure and convenient installation and use, the lubricating points can be increased, the unloading time of the pipelines is short, the grease concentrated and quantitative lubrication device can use lubricant grease of 0<#>, 1<#> and 2<#>, but not is limited to only use grease with small viscosity more than 00<#>.
Description
Technical field
The present invention relates to lubrication technical field, especially relate to the grease multiple spot and concentrate the unloading method in the quantitative lubricating system main line and inhale the lotus device.
Background technique
For reducing mechanical wear, keep its good operating condition, must be to the grease of regularly annotating of the moving element in the machinery.Moving element as machineries such as vehicles is numerous, needs often a plurality of positions fatten to be lubricated, and still adopts the mode of filling by hand at present mostly, and for the position resemble the automobile chassis, filling grease difficulty is very big, and the operating personnel is very arduous; Recently have some concentrated quantitative lubricating devices on the market, form by lubricant pump, distributor and pipeline etc., the distributor of these concentrated quantitative lubricating systems is broadly divided into two classes: a class is a stepwise type distributor, be sequential distributor or piece formula distributor again, this distributor manufacture difficulty is big, the user cost height; Another kind is the unloading type distributor, is positive displacement or differential pressure type distributor again, and its low cost of manufacture is easy to use, so adopt this distributor mostly; But its main in the course of the work oil feed line must just can be finished the filling of lubricant grease through release; This distributor is that a plurality of single line distributors combine through the dendroid connection; Owing to need multi point lubricating, therefore main oil supply pipeline branch is many, pipeline is long, though be furnished with unloading valve in lubricant pump, to the main oil feed line away from the pump housing, owing to the flow resistance of grease is big, unloading time is very long, even does not unload lotus, so can only adopt 00
#Or 000
#Grease lubrication, the lubricant grease that viscosity is big slightly just can't be annotated.
Summary of the invention
The objective of the invention is for overcoming the deficiency of prior art, the unloading method and the automatic lotus device of inhaling that provide a kind of grease multiple spot to concentrate the quantitative lubricating pipeline, can be after each pipeline distributor be pressed into grease and reaches authorized pressure at the lubricant pump of concentrating the quantitative lubricating system, during the termination of pumping release, pressure in the automatic suction line of energy, make the unloading type distributor smoothly to lubricating point filling grease, concentrated quantitative lubricating system is not limited to can only be with 00
#Above light viscosity oil fat, and can be with 0
#, 1
#, and 2
#Lubricant grease.
For achieving the above object, technological scheme of the present invention is such: a kind of grease multiple spot is concentrated the unloading method of quantitative lubricating pipeline, employing is provided with automatic suction lotus device on each main line of concentrating the quantitative lubricating system, this is inhaled the lotus device automatically and is connected on the pipeline that leads to quantitative distributor;
A kind of grease multiple spot is concentrated the automatic suction lotus device of quantitative lubricating pipeline, and it has a housing, and an end of housing connects a pipe joint, can be connected with lubricated main line, and the housing the other end is provided with pipe and connects the hole, joins by pipeline and unloading type distributor; One piston is arranged in the housing, can reciprocatingly slide along inner walls, pistons end is fixed a plug that is provided with oil through, and the piston the other end is provided with spring; The one side of plug is taken over over against oil-feed, and another side is aimed at oil through a steel ball, and steel ball places on the steel ball bracket, and the steel ball bracket has spring, and the steel ball bracket can move up and down along piston inner wall, realizes opening or closing of oil through.
Its working procedure is such: when the lubricant pump of concentrating the quantitative lubricating system when pipeline is pressed into grease, the automatic suction lotus device on the pipeline is because of the pressure reduction at two ends, piston moves the compression piston spring, is close to pipe until piston and connects the hole; Charge oil pressure continues to raise, thereby overcomes steel ball bracket spring force, makes steel ball along with moving apart oil through, and grease is entered by oil through, transports in each distributor through inhaling lotus device inner chamber automatically, and distributor is in and holds oil condition; After device to be allocated is pressed into grease and reaches authorized pressure, the termination of pumping release, automatically inhale the lotus device this moment and link to each other an end pressure with distributor greater than the end pressure that links to each other with main line, the steel ball bracket makes steel ball seal oil through under the effect of pipeline pressure reduction and steel ball bracket spring force; Then piston is pushed oil inlet pipe one end under the synergy of pipeline pressure reduction and piston spring power; Along with moving of piston, automatically the grease in the pipeline is included in the mobile formed cavity of automatic suction lotus device because of piston between suction lotus device and the distributor, the pipeline automatic pressure-relieving, with the one-way valve opens of distributor, the grease that has held in the distributor injects lubricating point immediately; When the lubricant pump of concentrating the quantitative lubricating system once more when pipeline is pressed into grease, the action of a beginning new round so moves in circles.
If on the pipeline automatic suction lotus device is not set, when the termination of pumping release of concentrated quantitative lubricating system, only depend on the unloading valve in the lubricant pump to concentrate off-load, because grease viscosity is big, to away from the grease on the pipeline of the pump housing, the resorption difficulty, unloading time needs very long, if grease viscosity is big slightly, it is impossible that oiling just becomes.
Owing to adopted technique scheme, the present invention to have simple, the compact structure of method, characteristics easy for installation can increase lubricating point manyly, and the pipeline unloading time is short, make concentrate the quantitative lubricating system to be not limited to can only be with 00
#Above light viscosity oil fat, and can be with 0
#, 1
#, and 2
#Lubricant grease has enlarged the application area of concentrated quantitative lubricating system.
