Abstract
The utility model relates to an improvement of a high pressure plunger pump which belongs to an air compressor accessory on a mine machinery rotary drilling machine. The utility model is mainly characterized in that a valve body is provided with a slide bar which is parallel to a plunger shaft, and a complex rocking arm mechanism is thrown off. Four ways of non-return valve are arranged in an oil supplying and draining loop for being locked, which ensures the safety of the oil supplying network. The utility model has the advantages of advanced structure, reliable operation and convenient maintenance and can ensure the lubricating requirement of an air compressor.
Description
The utility model relates to the further improvement of the lubricated plunger pump of air compressor annex on the mining machinery rotary drill.
Along with the development of mine production mechanization, it is very important that automatic lubricator seems.JZB-8 type high-pressure plunger pump in the market is exactly to force self-lubricated device for the main air compressor on import or the homemade rotary drill provides high pressure.It is slowed down by ratchet, drives plunger pump oil through cam, rocking arm, regulating lever, and structure is more numerous and diverse, and it is very inconvenient to adjust maintenance.Its regulating lever places in the rocking arm groove, and stuck fuel cut-off phenomenon happens occasionally.In addition, lubricating cup directly links to each other by an one-way valve with the valve body oil drain out, will seal incessantly oil behind the worn steel ball of valve, and the draining valve of will not opening during oil extraction causes fuel feeding to stop.
The purpose of this utility model is to provide a kind of structure advanced person, efficient height, the life-span is long, the adjustment maintenance is easy, lubricant pump easy to use.
The utility model is to realize like this, promptly comprising valve body, be furnished with the high-pressure plunger pump of the plunger axis that spring places valve body plunger axis hole, the one-way valve, fuel supply line, oil exit pipe, lubricating cup and the cam that link to each other with valve body oil supply and discharge loop, sour jujube gunlock structure, the former rocker arm body of cancellation plunger pump, on valve body, be parallel to plunger axis and design a slide bar, by connecting rod slide bar, plunger axis are connected together, by the cam that contacts with connecting rod the rotation of camshaft is become the to-and-fro motion of plunger axis again.In addition, four road one-way valve lockings are set in the oil supply and discharge loop, and mainly rely on the locking of steel ball gravity.Its feature is: in the sliding rod hole parallel with the plunger axis hole slide bar is set on valve body, a headband of slide bar is adjusted nut, the other end be connected the connecting rod that plunger axis contacts with cam in the middle part of it and link; Vertical oil drain out one-way valve and the oil-feed port one-way valve that links to each other with the plunger axis hole that be provided with on valve body, these two one-way valves all rely on the steel ball gravity locking of differing in size; The vertical two-way seat that connects on valve body oil drain out one-way valve, two-way seat upper vertical connects a lubricating cup, and there is an one-way valve by steel ball locking the lubricating cup lower end, and the one-way valve that lubricating cup top is formed by a spring and steel ball links to each other with the high-pressure plunger pump oil exit pipe; Being full of the glycerine additive and oil droplet vertically is set in above-mentioned lubricating cup can be along the wire of its rising.
The utility model has the advantages that the structure advanced person, it adopts high-pressure oil feed, the locking of multiple tracks one-way valve.Its fuel feeding networking security is reliable, keeps in repair easy to adjustly, can guarantee the self oiling needs of air compressor.
Below in conjunction with embodiment's accompanying drawing the utility model is further described.
Fig. 1 is a JZB-8 type high-pressure plunger pump schematic diagram.
Fig. 2 is the utility model schematic diagram.
Fig. 3 is the utility model structural representation.
Can be well understood to the improvement situation of cam rocker arm mechanism by Fig. 1 and Fig. 2, also can be well understood to the improvement situation of one-way valve in the fuel feeding process.In Fig. 3, (1) is valve body, (2) for being furnished with the plunger axis that spring (3) places the plunger axis hole, (4) are adjusted nut (5) other end and are connected the continuous slide bar of connecting rod (6) that plunger axis (2) contacts with cam in the middle part of it for being arranged on a headband in the sliding rod hole.(7) and (8) be respectively vertically disposed oil drain out one-way valve and filler opening one-way valve.Coaxial but in the interior step hole that differs in size steel ball not of uniform size (9) and (10) are being set on this one-way valve, with the hole of steel ball sealing can be taper hole, can not be taper hole also.(11) for being vertically connected on the two-way seat on the oil drain out one-way valve (7), vertically connecting lubricating cup (12) on it, lubricating cup (12) bottom is being provided with another one-way valve that is made of steel ball (13), steel ball seat (14), lubricating cup (12) top is provided with the one-way valve that is made of steel ball (15), spring (16), and oil pipe runs on one-way valve top.Be full of in the lubricating cup (12) and be certain proportion by G ﹠ W and mix the glycerine additive constitute, its central vertical is provided with a wire (17), (18) for being connected the oil inlet pipe on the filler opening one-way valve (8).When plunger axis (2) when moving downward, the plunger hole internal volume enlarges pressure and diminishes, and oil-feed port one-way valve (8) is opened, and oil drain out one-way valve (7) is closed, and the lubricant oil in the fuel tank enters in the plunger pump from oil inlet pipe (18).When plunger axis (2) when moving upward, filler opening one-way valve (8) is closed, and oil drain out one-way valve (7) is opened, and oil enters in the two-way seat (11).The plunger axis to-and-fro motion, oil constantly enters two-way seat, at last under the high pressure oil effect, the one-way valve that is made of steel ball (13), steel ball seat (14) is opened, oil enters the lubricating cup that is full of the glycerine additive, be oily beans shape along wire (17) and float to above the lubricating cup, and the one-way valve of opening by steel ball (15), spring (16) formation enters oil feed line.
Claims (1)
