Description

The invention relates to centralized lubricating systems of periodic action, in particular to injection devices for the dosed supply of lubricant to the rubbing surfaces of machine tools and other machines and mechanisms.

A known lubrication system (Bulletin 71000, LUBRIQUIP company (USA) dated 07/11/2001), comprising a lubricating pump, the outlet of which is equipped with a sequential-action lubricating feeder of the first stage with a control device connected to it - a cycle relay, which provides centralized control over the supply of lubricant to every consumer. At the same time, indicators of overpressure are installed on each output channel of the feeder of the first stage, allowing to determine the consumer who is not taking the dose of lubricant intended for him when the required number of signals have been received from the cycle relay in the allotted time interval, indicating the completion of the full lubrication cycle. In this case, the time interval from switching on to the subsequent switching on of the cycle relay is the time interval of the cycle of the feeder, and the fulfillment of the required number of cycles of operation by the feeder indicates the completion of the full lubrication cycle. The output channels of the sequential-action feeder of the first stage are connected to the sequential-action feeders of the second stage, the output channels of which are connected to consumers.

The disadvantages of this lubrication system are the inability to independently supply a dose of lubricant to each output channel of the first stage feeder, i.e. providing an independent lubrication mode for consumer groups connected to the output channels of this feeder, and determining a consumer who is not taking the dose of lubricant intended for him without using additional devices (overpressure indicators), as well as the difficulty of setting the lubrication system so that when the lubricant pump is turned off, the metering the distribution pistons of the feeder of the first cascade always stopped in a fixed initial position, the absence of which leads to unequal The black supply of lubricant to at least the outlet channel of the first stage feeder, to which the dose of lubricant is first supplied at the beginning of the lubrication cycle.

Uneven feed due to the fact that each element of the lubrication system has a response time, i.e. time from the receipt of the signal to its execution. At the same time, during the time interval from the receipt of the signal from the cycle relay to the shutdown of the lubricating pump, at least one metering and distribution piston that works next to the metering and distribution piston and from which the cycle relay is activated, can move up to 300 cycles per minute, may move and give the consumer a dose of lubricant that is excessive in the current lubrication cycle.

With a constant time interval from the signal from the cycle relay to the shutdown of the lubricant pump, the supply of an excess dose of lubricant will be repeated in every second cycle of the feeder.

If, in subsequent cycles of the feeder, the time interval from the receipt of the signal from the cycle relay to the shutdown of the supply of the lubricating pump will change, for example, due to the fact that when using a piston type lubricating pump with a hydraulic or pneumatic drive, the signal from the cycle relay will come already in a different position the piston of the lubricating pump, which, having inertia, continues to give out lubricant for some time after turning off the drive, the dosing error can accumulate as a result (since the cycle of the feeder used to read from switching cycle to switching relays) has several output channels may be fed feeder excess lubricant dosage.

The greatest dosing error is manifested in a situation where it is necessary to supply the consumer with a minimum dose of lubricant for one cycle of the feeder when using a large-capacity lubricating pump.

Partially indicated drawbacks were eliminated in the lubrication system, which included special electrically controlled hydraulic switchgears (Bulletin 10102 manufactured by LUBRIQUIP (USA) dated 07.2000) installed parallel to the lubricant supply line between the lubricating pump and the lubricating feeders of the first stage, which allows isolating consumer groups, the lubricant supply order, which can be set using the control system.

The disadvantages of such a lubrication system are: the lack of centralized control (in this lubrication system, centralized control of the supply of lubricant to each individual consumer group is implemented using a separate cycle relay), the inability to determine the output of the first cascade feeder that does not accept the dose of lubricant intended for it without using additional control devices, as well as the difficulty of setting the lubrication system so that when disconnecting the first qada from the lubricating pump of dosing and distribution pistons always stayed in a fixed initial position.

Known lubricating feeder containing more than three metering and distribution pistons (as.with. RF 1350444 A1, IPC class F 16 N 25/02, 1987), equipped with control channels and control chambers, and the control channels of the previous metering and distribution piston communicated with the control cameras later, the feeder is equipped with at least one distributor with external control with four inputs connected to the control channels, and four outputs connected to control chambers installed with the possibility of from the metering and distribution pistons of at least one group containing at least three metering and distribution pistons, while in one position of the dispenser, each of its inputs is connected with a corresponding output, and in a different position, the inputs and outputs of the dispenser communicated with a group of metering and distribution pistons are interconnected in pairs, and the remaining inputs and outputs are muffled.

The disadvantage of this feeder is the complexity of the design and the inability to determine the output that does not accept the intended dose of lubricant without the use of additional control devices.

The closest in technical essence and the achieved effect to the claimed injection device is an injection device (AS RF No. 679772, class IPC F 16 N 25/02, 1977), containing a lubricating pump connected by a central channel passing in the housing switchgear, with bores for its elements, in each of which a double-acting metering and distribution piston with control belts and grooves is located, which forms the ends of the working chambers in the bore, while the bores are connected in series about two auxiliary channels, and the working chambers are equipped with output channels, some of which are connected with portion consumers and discharge directly, and the rest through load devices.

The disadvantages of such a discharge device are the complexity of the feeder design, the impossibility of an independent mode of supplying a dose of lubricant to each of its output channels and determining the output that does not accept the dose of lubricant intended for it without the use of additional control devices, the inability to distinguish consumer groups with an independent lubrication mode, and the complexity of setting up the discharge device so that when the lubricant pump is turned off, The distributor pistons of the feeder always stopped in a fixed initial position.

The purpose of the present invention is to increase the metering accuracy and lubrication efficiency, expand the functionality, scope, simplify the design and provide automated diagnostics of the state of periodic lubricating systems.

This goal is achieved by the fact that in the discharge device containing a container with a lubricant with a lubricating pump installed on it, connected by a central channel passing in the feeder housing, with bores for its elements, each of which has a double-acting metering and distribution piston with control belts and grooves, forming the working chambers with the ends in the bore, while the bores are connected in series by two auxiliary channels, and the working chambers are equipped with output channels by the channels connected with consumers, and in one of the working chambers a cycle relay is installed, on the output channel of the feeder, into which the dose of lubricant enters when the lubricant pump is switched on, a directional control valve is installed with an external control that blocks the possibility of supplying lubricant from this at the end of the cycle of the feeder the output channel, and the cycle relay, which controls the cycle of the feeder, is installed in the working chamber, in which, ending its reciprocating movement at the end of the full cycle of the power supply At the end of the process, the last metering and distribution piston arrives, opening up the possibility of supplying a dose of lubricant to the output channel of the feeder, in which a control valve with external control is installed.

An external control valve can be installed in each output channel of the feeder, which, upon a signal from the control system, ensures that the output channel is connected to the consumer or to the drain line to return the lubricant to the lubricant tank.

All metering and distribution pistons of the feeder can be made of the same minimum size with two output channels.

A consumer or a group of consumers can be connected to one output channel of the feeder, affecting the readings of the same power consumption sensor installed in the drive system.

Each valve with external control can be fixed in the control system for a specific output channel of the lubricating feeder.

All pipelines of exits of hydrodistributors with external control, which should be connected to the drain line at the signal from the control system, can be assembled into one drain collector, at the end of which a flow switch is installed, which forms an electrical signal when a set dose of lubricant passes through it.

Non-flowing consumers requiring connection with a drain can be connected to the feeder through an external control valve, connecting in one of their positions non-flowing consumers with a drain line, in which, if necessary, a load device can be installed that provides the necessary back pressure when the consumer is connected to the drain.

At least one more feeder can be connected to the lubricating pump parallel to the first feeder, equipped with all the necessary devices, while only one flow switch is installed in the combined drain line.

Figure 5 shows a diagram of a discharge device that provides the possibility of identifying independent zones with the same requirements for the lubrication mode, as well as supplying lubricants to a large number of consumers that are not provided by the design capabilities of a single feeder.

The injection device shown in FIG. 1 contains a container with a lubricant 1 with a lubricant pump 2 installed on it, connected by a communication line 3 to a central channel 4 passing in the housing of the feeder 5. The feeder consists of at least three elements, each of which has a bore 6 , 7, 8. In the bores are dispensing and distribution pistons 9, 10, 11, having on their surface belts 12-20 and grooves 21-26. The ends of the metering and distribution pistons and bores form the working chambers 27-32. Bores of all elements by drilling 33, 34, 35 and the central channel 4 are connected by a communication line 3 with a lubricating pump 2. All elements are connected in series by auxiliary channels 36-41. Each element has two output channels 42-47 connected to the bores 6, 7, 8. Moreover, channel 42 is an output channel for the working chamber 28, and channels 43 - 47 are output for the working chambers 27, 29-32, respectively. In the working chamber, into which, ending its reciprocating movement at the end of the full cycle of the feeder, the metering and distribution piston comes, opening up the possibility of supplying a dose of lubricant from the output channel associated with the working chamber, from which the dose of lubricant will first come at the beginning of the cycle of the feeder, for example in the working chamber 32, into which the metering and distribution piston 11 comes, opening up the possibility of supplying a dose of lubricant from the output channel 43, knitted to the working chamber 27, set switch 48. In this cycle in the outlet duct 43 installed control valve 49 with an external control, which in one of its positions allows free passage of lubricant to the consumer 50, portioned, and in the other - it overlaps.

Moreover, the output channels 42, 44-47 are directly connected with portion consumers 51-55, respectively.

In the pressure device shown in FIG. 2, in addition to the structural elements shown in FIG. 1, an external control valve 56 is installed between the external control valve 49 and the associated portioned consumer 50, which provides free passage of lubricant in one of its positions material to the consumer 50, and in the other - its discharge into the drain line 57, associated with the lubricating tank 1. If necessary, the valves 49 and 56 can be combined into one design that provides a complete set of functions performed by them.

External control valves 58-62, respectively, are installed directly in the output channels 42, 44-47, which, in one of their positions, provide free passage of lubricant to portion consumers 51-55, and in the other, its discharge into the drain line 57.

In the injection device shown in FIG. 3, in addition to the structural elements shown in FIG. 2, a flow switch 63 is installed in the drain line 57 just before it is connected to the lubricating tank 1, through which all doses of lubricant coming from the control valves 57- 61 with external control when they are in a position allowing the lubricant to be discharged to the drain line 57.

In the injection device shown in FIG. 4, in addition to the structural elements shown in FIG. 3, between the outlet channel, for example 47, and a non-flowing, batch, requiring connection with a drain consumer 55, an external control valve 64 is installed, which in one of its position provides free passage of lubricant to the consumer 55, in the other - its discharge into the drain line 57, and in the third - the consumer 55 through the load device 65 is connected to the drain line 57. The load device 65 can It is not installed, while the consumer 55 will communicate directly with the drain line 57.

In the discharge device shown in FIG. 5, in addition to the structural elements associated with the feeder shown in FIG. 4, at least one more feeder is connected in parallel with the first feeder via a communication line 66 to the lubrication pump 2. Moreover, for automated centralized control of the accuracy of doses issued from each output of each feeder, only one flow relay 62 is used.

The discharge device shown in figure 1, operates as follows. When a signal is supplied from a control system (not shown), the control valve 49 switches to the position (right in the drawing), which opens up the possibility of supplying lubricant from the outlet 43 to the consumer 50, and the lubricant from the tank 1 by the lubricating pump 2 through the communication line 3 is fed to the central channel 4 of the feeder 5, from where, by drilling 33 through the groove 25, through the auxiliary channel 37 it enters the working chamber 28. In this case, the metering and distribution piston 9 moves to the left position in the drawing, moving the lubricant from the working chamber Step 27 through the auxiliary channel 36, the groove 26, the output channel 43, through the valve 49 to the consumer 50.

Moving the metering and distribution piston 9 to the left position according to the drawing connects the working chamber 29 with the output channel 44, which was previously filled with lubricant received from the lubricant pump 2 through the central channel 4, drilling 35, the groove 21 and the auxiliary channel 38, and was cut off from the output channel 44 by the belt 12 of the metering and distribution piston 9, and makes it possible to move the metering and distribution piston 10.

The previously described method will move the metering and distribution pistons 10 and 11 to the left position in the drawing.

In this case, the movement of the metering and distribution piston 11 will lead to a change in the state of the cycle 48 relay and the control system will receive a signal that the feeder 5 has completed the first half of the operation cycle, according to which the valve 49 will switch to the left position in the drawing, blocking the possibility of re-feeding the dose of lubricant to the consumer 50 in the current cycle of the feeder.

This ensures a guaranteed time interval of half the cycle time of the feeder to pass the signal and the operation of the valve with external control.

Similarly, the metering and distribution pistons 9, 10, 11 are moved to the right position in the drawing. In this case, the last, in the current cycle of the feeder’s operation, the metering and distribution piston 11 will come to the right position in the drawing, the state of the relay of cycle 48 will change and the control system will receive a signal that the feeder 5 has completed the full cycle of operation, according to which the supply of lubricant from pump 2 is turned off .

In cases where in order to fully ensure the required dose of lubricant for each consumer, it is necessary for the blower to operate several cycles, its operation is carried out as described above, with the only difference being that the supply of lubricant to the first consumer, for example consumer 50, is blocked and the lubricant pump is turned off carried out on the last cycle of the feeder 5.

With this operation scheme, the possibility of re-moving the metering and distribution piston 9 in the second half of the cycle of the feeder 5 is excluded when the lubricant pump supplies an excess portion of the lubricant due to the time during which the pump 2 actually stops from the moment the signal was issued for its shutdown.

The discharge device shown in figure 2, in the case when the control valves 56, 58-62 are in the initial position, i.e. in the position right in the drawing, it works in the previously described way, with the only difference being that along the route from the output channels 42-47 to consumers 51, 50, 52-55, the lubricant also passes through the control valves 58, 56, 59-62, respectively .

If it is necessary to supply one or more consumers with an increased dose of lubricant that is a multiple of the volume of the working chamber to which they are connected, in the first cycle of the supercharger operation the control valves 56, 58-62 will be in the initial position, and in each subsequent cycle in the position of connecting to the consumer there will be only hydraulic valves connected to consumers requiring an additional dose of lubricant, and all other hydraulic valves will be switched to a position ensuring the removal of lubricant full-time of the material from the corresponding outlet of the feeder 5 through the drain line 57 into the oil tank 1. For example, in the case when necessary for the user 55 dose of lubricant can only be obtained when issuing from the working chamber 47 of the two volumes of the lubricant, i.e. the volume provided by the double actuation of the metering and distribution piston 11, the operation of the supercharger in an additional cycle of work is as follows.

When a signal is supplied from the control system to an additional cycle of the supercharger in order to provide the consumer 55 with a double dose of lubricant, the control valves 56, 58-61 switch to the position in which the lubricant from the output channels 43, 42, 44 - 46, respectively, will enter the drain line 57, and the control valve 62 will be in the position that connects the output channel 47 to the consumer 55. When the supercharger completes the additional cycle of work previously described in the way, the consumer 55 will be served until a full dose of lubricant.

In a similar way, an additional dose of lubricant can be supplied to each consumer. The presence of this possibility allows the use of feeders in the injection device, in which all metering and distribution pistons are made of the same minimum size with two outputs, which simplifies their design. In this case, the required dose of lubricant for each output channel of the feeder is dialed due to the required number of connections of the corresponding working chamber to the consumer.

In cases when the feeders of the second stage are connected to the output channels of the supercharger as consumers, it is possible to independently lubricate the groups of consumers associated with the feeders of the second stage with centralized monitoring and control of the lubrication cycle using one relay of cycle 48.

A signal to perform a supercharger operation cycle in order to provide an additional dose of lubricant to one or several consumers can be either incorporated into the control system program at the equipment design stage, or it can be generated by a signal from an additional device (not shown in the drawing), for example, a pressure switch in the system hydraulic drive of the lubricated unit or a special relay for changing the power consumption in the system of the electric drive of the lubricated unit, if to one output channel Tutelo connected consumer or group of consumers, affecting the readings of the same sensor in the drive system. In this case, depending on the readings of the power consumption sensor, an additional portion of lubricant may be supplied to a specific consumer or group of consumers in order to reduce the power consumed by the drive.

In the case when each directional control valve with external control will be assigned to a specific consumer in the control system program, it becomes possible to carry out automated diagnostics of consumers' condition in order to identify a consumer who is not taking the dose of lubricant intended for him when, when the feeder is operated by a cycle relay 48 within a certain period of time there will be no signal about the completion of the cycle of the feeder. At the same time, the possibility of implementing sequential operation of the supercharger, in which only one consumer communicates with the output channel in one cycle of the feeder to obtain the portion of lubrication intended for it, allows using the signal from the relay of cycle 48 to realize the diagnostic cycle of the supercharger, in which at the initial moment everything the output channels of the feeder using external control valves will be connected to the drain, and then they will be connected to consumers one at a time, and the connection will be distributed I, which does not lead to the triggering of the relay cycle 48, and will point to the consumer, who does not accept its intended dose of lubricant. The presence of this possibility allows not to include indicators of excess pressure installed on each of its output channels in the composition of the feeder in order to determine the consumer who does not accept the dose of lubricant intended for him.

The discharge device depicted in FIG. 3 operates similarly to the discharge device shown in FIG. 2 in the previously described manner. At the same time, the flow switch 63 installed in the drain line 57 is adjusted to the dose of the lubricant, deviation from which is unacceptable and indicates a malfunction of the supercharger and at the time when the controlled dose is supplied to the drain line when the corresponding valve is switched, the control system monitors the signal from the flow switch, on the basis of which a signal is formed about the serviceability of the discharge device.

In the case when all the working chambers of the feeder 5 will have the same working volume, using one flow switch 63 it is possible to control deviations from the required dose of lubricant dispensed from all the output channels of the discharge device.

The discharge device shown in FIG. 4 operates similarly to the discharge device shown in FIG. 3 in the previously described manner. In this case, the supply of lubricant to non-flowing, batch, consumers requiring connection with a drain (for example, dispensers in a pulse lubrication system), for example, consumer 55, is carried out through a control valve 64, which, by a signal from the control system, connects the output through one of its positions channel 47 with the consumer 55, and by a signal to connect the consumer to the drain line, it switches to the right position in the drawing, connecting the consumer 55 through the load device 65, and when its absence - directly with the drain line 57. When switching the valve 64 to the left position in the drawing, the output channel 47 is connected to the drain line 57.

The composition of the discharge device shown in figure 5, includes at least two feeders 5 with connected to them a set of devices shown in figure 4. Each of the feeders is connected in parallel to the lubricating pump 2 and operates similarly to the discharge device shown in Fig.4. The sequence of operation of the feeders 5, the number and sequence of lubrication of consumer groups connected to each feeder is set by the control system program and is carried out with the switching of directional control valves 49 with external control. Since the feeders 5 can only work sequentially, an automated centralized control of the accuracy of the doses given from each output of each feeder is carried out using one flow relay 64 using the control system program.

Thus, the installation of an external control valve in the discharge device on the output channel of the feeder, into which the dose of lubricant enters when the lubricant pump is turned on, allows to increase the metering accuracy and lubrication efficiency due to the fixed stop of the metering and distribution pistons in the initial position, which excludes the possibility of supplying excess doses of lubricant, and also allows you to expand the scope of the discharge device by providing the possibility These connections are parallel to the grease pump of the two feeders. The sequence, quantity and sequence of lubrication of consumer groups connected to these feeders is set by the program of the control system for switching on this valve.

The installation in each output channel of the feeder of the discharge device of the directional control valve with external control, which by the signal from the control system ensures the connection of the output channel to the consumer or to the drain line, allows using the control system to set an arbitrary lubrication cycle for consumers connected to one output channel of the feeder of the discharge device. At the same time, connecting to a single output channel of a consumer feeder or a group of consumers that affect the readings of the same power consumption sensor installed in the drive system can improve lubrication efficiency and reduce the power consumed by the drive.

Connecting to the injection device as consumers of the second stage feeders expands the scope of its application, providing the possibility of an independent lubrication mode for consumer groups associated with the second stage feeders with centralized control and lubrication cycle control using one cycle relay 48.

Fixing in the program of the control system of each directional control valve with an external control to a specific outlet of the injection device allows automated diagnostics to identify consumers who are not taking their dose of lubricant without additional devices, which simplifies the design of the injection device.

The use of feeders in the delivery device, in which all metering and distribution pistons are made of the same minimum size with two output channels, also simplifies its design, and the combination of all the pipelines of the outputs of the directional control valves with external control, which should be connected to the drain line at the signal from the control system one drain manifold, at the end of which a flow switch is installed, allows centralized diagnosis of the status of the discharge device properties by controlling the deviation of the dose of lubricant entering each output channel of the discharge device from the value set on the flow switch.

The use of a loading device as a part of the injection device, connected with an external control valve, which in one of its positions provides free passage of lubricant to the consumer, in the other - its discharge to the drain line, and in the third - the consumer's connection to the drain line through the load device , allows you to expand the scope of the discharge device due to its use as to provide lubricant stagnant, portioned, requiring connected I am with a drain of consumers (for example, dispensers of pulsed lubricating systems), and consumers requiring, for example, an additional dose of lubricant depending on the sensor for changing the power consumption installed in the drive system of the lubricated assembly, as well as two consumers requiring alternating connection to the lubricant the pump so that when one consumer is connected to the lubrication pump, the other is disconnected from it and vice versa (for example, reversible inlet sections of the lubrication systems after positive action of the reverse type).
