(54) СИСТЕМА СМАЗКИ(54) LUBRICATION SYSTEM

1one

Изобретение относитс к смазочиым системам и может быть использовано дл смазки стаиков, кузнечно-прессового оборудовани и других машин и механизмов.The invention relates to lubricating systems and can be used to lubricate stakes, press-forging equipment and other machines and mechanisms.

Известны смазочные системы, включающие устройство подачи смазки, питатели и устройства контрол подачи, содержащие подпружиненный порщень и щток, расположенные в цилиндрической расточке корпуса с каналом подвода, соединенным трубопроводом с выходной полостью питател , и с каналом отвода, и датчик электрической сигнализации 11 .Lubricating systems are known, which include a lubricant supply device, feeders and supply control devices containing spring-loaded bristles and jaws located in the cylindrical bore of the housing with a supply channel connected by a pipeline to the output cavity of the feeder, and with a drain channel, and an electrical alarm sensor 11.

При прохождении смазочного материала от питател к смазЬшаемой точке порщень движетс и св занным с ним щтоком воздействует на микропереключатель, что позвол ет вести дистанционный контроль за поступлением смазочного материала, а также использовать этот сигнал в электросхеме управлени смазочной системой.When the lubricant passes from the feeder to the lubricated point, the powder moves and the associated brush actuates the microswitch, which allows remote control of the lubricant flow, as well as using this signal in the lubricant control circuitry.

Недостатком известиой системы вл етс то, что при применении в ее составе импульсных питателей (дозирующих устройств), в которых формирование дозы происходит благодар разности площадей расточек корпуса под порщень и двойной клапан, в трубопроводе между питателем и устройством контрол по вл етс разрежение, что значительно снижает надежность работы системы.The disadvantage of the lime system is that when using pulsed feeders (metering devices) in its composition, in which dose formation occurs due to the difference in the area of body bores under the piston and double valve, a vacuum appears in the pipeline between the feeder and the control device, which significantly reduces the reliability of the system.

По вление разрежени св зано с тем, что в указанных питател х рабочий объем выходной йолости питател (объем полости над поршнем , образующейс при перезар дке питател ) больще объема дозы, поступающей в эту полость из дозирующей полости питател .The occurrence of a dilution is related to the fact that in these feeders the working volume of the output feeder (the volume of the cavity above the piston formed during the recharging of the feeder) is greater than the volume of the dose entering the cavity from the feeder dosing cavity.

Целью насто щего изобретени вл етс повыщение надежности системь смазки путем устранени разрежени в трубопроводе.The purpose of the present invention is to increase the reliability of the lubrication system by eliminating the vacuum in the pipeline.

Claims

The goal is achieved by the fact that a check valve is installed in the lubricant supply control device, and an additional channel is connected in the lubricant connecting the inlet and outlet channels, while the reverse one. the valve is installed in the additional channel and is mechanically connected with the rod, the stroke of which is longer than the stroke, and the working volume of the control device is equal to or greater than the difference 37 of the working volume of the output cavity and the supply volume of the pulse feeder. FIG. 1 shows a diagram of a pulse lubrication system with control devices for lubricant supply; in fig. 2 - control unit for lubricant supply The system contains a device 1 for pulsed lubricant supply (lubrication station), pulsed feeders 2 and devices 3 for supply control. The pulsed lubricant supply unit is connected to the imgg / low power supply pipelines 4, and subsequently the pipelines 5 to the feed control devices, the outputs of which are connected to the pipelines 6, go directly to the lubrication points. . The feed control device comprises a housing 7 with an inlet 8, a cylindrical bore 9 and an outlet 10, a check valve 11 with a stem 12 located in porishe 33, which is a clan seat and having a seal 14, a spring 15, a sensor 16 with a seal 17 and stop 18. The system works as follows. When the device 1 creates an integral lubricant supply of pressure; The lubricant is supplied by pipelines 6 to line 4 and is supplied to the pulse feeders 2, which work and supply pipelines 5 to the cooTBexcTBjiomMN 3 supply control devices, from where they are supplied to the lubrication points via pipelines 6. A lubricant is passed through the inlet 8 of the housing 7 and further to the supply control device. The shchindric boring 9 under the piston 13, which together with the check valve Pi moves the shaft 12, compressing the spring 15 until it stops 18. After the piston stops, the return valve opens, the lubricant material in the volume of the different feed of the feeder enters the outlet 10. At the same time A stem connected to a check valve acts on the sensor 16, which outputs an electric sigal. After the end, the flow valve is closed. When reloading the pulse bus, when the pulsed lubrication device operates in unloading mode, the piston of the control device under the action of ITPJOKHHM returns to its original position, determined by the difference between the displacement of the output cavity of the engine and the supply volume. In this case, the piston will not reach the end of the body bore from the inlet side of the inlet, since the working volume of the control device cavity is greater than the difference between the working volume of the output cavity and the supply volume of the pulse feeder. Therefore, a vacuum in the pipeline between the feeder and the control device is not formed. In the extreme case, the working volume of the cavity of the control device can be equal to the indicated difference, and the piston will reach only the torus. Dilution in this case also does not occur. Thus, when the lubricant reaches the lubricated points, each Dicle is accompanied by a signal from the normal operation. If the feeder piston does not move due to the blockage of pipelines or its jamming, then the lubricant is not supplied and the piston and the rod of the device do not move. There is no normal operation signal. In case the lubricant does not flow from the metering cavity of the feeder to its output cavity, the piston of the control device when recharging the feeder will move from the stop beyond the previous initial position by the amount determined by the feed volume, and during the subsequent lubrication cycle the piston of the control device reaches the stop but the check valve does not open and the stem does not act on the sensor. There is no normal operation signal. Thus, the proposed device allows monitoring all possible conditions for non-admission of lubricant to lubricated points.
