Abstract
The utility model discloses a plunger synchronous lubricating device capable of regulating lubricating oil mass. The plunger synchronous lubricating device capable of regulating the lubricating oil mass comprises a plunger pump body, a sealing box body and a plunger. One side of the plunger pump body is fixedly connected with the sealing box body, a front end of the sealing box body is fixedly connected with a diaphragm pump, a driving end A which is matched with the plunger and the diaphragm pump in a sliding mode in a back end chamber body, a plunger pump body, a volume chamber B which is formed by and communicated with the sealing box body. An oilring is arranged inside the chamber body of the sealing box body, and a packing ring is arranged on two sides of the oilring and is matched with the plunger in a sealing mode; an oil inlet hole is arranged on the sealing box body which is opposite to the oilring. An oil inlet opening pipeline of the diaphragm pump is connected with an oil tank and an oil outlet opening pipeline is connected with the oilring through the oil inlet hole on the sealing box body. The plunger synchronous lubricating device capable of regulating the lubricating oil mass has the advantages that lubricating oil is direct injected into a plunger friction pair, and accordingly service life of all parts of the plunger friction pair is greatly prolonged, operational reliability of the plunger pump is improved; the lubricating oil mass can be regulated on demand so that the lubricating oil is saved; friction loss of the plunger friction pair is reduced and energy is saved.
Description
Technical field
The utility model relates to a kind of plungers pump plunger lubricating fitting, particularly relates to a kind of piston lubricator of can regulate lubricants capacity.
Background technique
The application of reciprocating pump is very extensive, in use, if can carry out good lubricating, with the working life that prolongs plunger and filler greatly to the friction pair of plunger and filler.Patent of invention 200710015802.X " piston lubricator " is exactly through to plunger surface oil jet lubrication plunger.But the deficiency of this patent of invention is lubricant oil and can only be difficult to get into the friction pair of plunger and filler at plunger surface, also needs external power fuel feeding, the waste lubricant oil and the undesirable energy of having wasted again of effect.Utility model patent 201020275445.8 " reciprocating plunger pump piston lubricator " drops in the lubricated plunger of plunger surface with lubricant oil.But the deficiency of this utility model patent is lubricant oil and can only be difficult to get into the friction pair of plunger and filler at plunger surface that waste lubricant oil and effect are undesirable.Patent of invention 200810163688.x " synchronous-isolation plunger pump " is though can inject lubricant oil the friction pair of plunger and filler; But directly contact with pumped medium owing to isolate oil; Pumped medium there is certain requirement, 1, just inapplicable with the medium of isolating the biochemical reaction of fry dried food ingredients for those; 2, just incompatible for those density medium very approaching with isolating oil; When 3, the plunger pump pump speed was higher, medium mixed with isolation oil easily, influences lubrication effect.
Summary of the invention
The utility model is intended to the deficiency that exists in the background technique, and the piston lubricator of a kind of can regulate lubricants capacity that proposes.
The plunger synchronous lubricating device of a kind of can regulate lubricants capacity of the utility model; Form by plunges pump body, sealed letter body and plunger; One side of plunges pump body affixed the sealed letter body, be connected with the plunger that is being slidingly matched in diaphragm pump, the rear end cavity at the front end of sealed letter body and form the cavity volume B that communicates with drive end A, plunges pump body, the sealed letter body of diaphragm pump.In the cavity of sealed letter body, be provided with oil ring, be provided with packing ring in the both sides of oil ring and be sealed and matched mutually with plunger; On the sealed letter body relative, be provided with oil inlet hole with oil ring.The filler opening pipeline of diaphragm pump is connecting fuel tank, the oil outlet pipeline is connected with oil ring through sealed letter body oil inlet hole.
As the further improvement of the utility model, be provided with barrier film in the inside of diaphragm pump, the top is provided with the regulator plate assembly.
The beneficial effect of the utility model is; Lubricant oil directly is injected into piston friction pair, has prolonged the working life of all parts of piston friction pair greatly, has improved the plunger pump operational reliability; Lubricants capacity can be regulated as required, has saved the consumption of lubricant oil; Reduce the frictional loss of piston friction pair, practiced thrift the energy.

Embodiment
Plunger synchronous lubricating device below in conjunction with 1 pair of a kind of can regulate lubricants capacity of the utility model of accompanying drawing further specifies:
The plunger synchronous lubricating device of a kind of can regulate lubricants capacity of the utility model; Form by plunges pump body 1, sealed letter body 2 and plunger 3; One side of plunges pump body 1 affixed sealed letter body 2, be connected with the plunger 3 that is being slidingly matched in diaphragm pump 5, the rear end cavity at the front end of sealed letter body 2 and form the cavity volume B that communicates with drive end A, plunges pump body 1, the sealed letter body 2 of diaphragm pump 5; In the cavity of sealed letter body 2, be provided with oil ring 11, be provided with packing ring 4 in the both sides of oil ring 11 and be sealed and matched mutually with plunger 3; On the sealed letter body 2 relative, be provided with oil inlet hole 12 with oil ring 11; The filler opening pipeline 6 of diaphragm pump 5 is connecting fuel tank 7, oil outlet pipeline 8 is connected with oil ring 11 through sealed letter body 2 oil inlet holes 12.Diaphragm pump 5 inside are provided with barrier film 9, the top is provided with regulator plate assembly 10.When the plunger 3 of plunger pump is made suction stroke; Under the suction function of barrier film 9 in cavity volume of miniature diaphragm pump 5; Also make suction stroke synchronously, lubricant oil is inhaled into the miniature diaphragm pump 5 through pipeline 6 from fuel tank 7, when the plunger 3 of plunger pump is done to discharge stroke; Medium in the cavity volume promotes the barrier film 9 of miniature diaphragm pump 5 and also does synchronously to discharge stroke, and lubricant oil is discharged in the oil ring 11 through pipeline 8.So constantly circulation.
Axial direction along miniature diaphragm pump 5 septations 9; Move the axial position of regulator plate assembly 10; Also just change the effective travel length of miniature diaphragm pump 5 septations 8, very simply changed the lubricant oil discharge capacity of miniature diaphragm pump 5, thereby regulated the consumption of lubricant oil.
