Alternative embodiments of the present disclosure are described in detail below with reference to the drawings.

Fig. 1 is a schematic structural diagram of an automatic jigger according to some embodiments of the present disclosure, where fig. 1 illustrates a connection relationship between the automatic jigger and a crankshaft of a compressor, and does not illustrate a specific structure of the compressor. As shown in fig. 1, some embodiments of the present disclosure provide an automatic jigger apparatus 100 for a compressor, the automatic jigger apparatus 100 including a hydraulic motor 10, a jigger oil pump 20, a first oil passage 31, and a second oil passage 32.

The hydraulic motor 10 is fixedly connected with a crankshaft 50 of the compressor through a first coupling 41 and is configured to drive the crankshaft 50 of the compressor to rotate to realize automatic jigger. Specifically, the rotation shaft of the hydraulic motor 10 is fixedly connected, for example detachably fixedly connected, with the crankshaft 50 of the compressor by the first coupling 41, so that the rotation shaft of the hydraulic motor 10 always rotates synchronously with the crankshaft 50 of the compressor.

The jigger oil pump 20 is connected to the hydraulic motor 10 through a first oil passage 31, and is configured to output high-pressure lubricating oil to power the hydraulic motor 10 to perform jigger operation of a compressor. The hydraulic motor 10 operates under the driving of the jigger oil pump 20, outputs torque to drive the crankshaft 50 of the compressor to rotate or has a tendency to rotate, provides auxiliary torque for the start of the driving motor of the compressor, and reduces the starting torque of the driving motor, thereby reducing the starting current.

The second oil passage 32 connects the hydraulic motor 10 and the bearing portion 51 of the crankshaft 50, and is configured to transmit the lubricating oil flowing through the hydraulic motor 10 to the bearing portion 51 to lubricate the bearing portion 51, facilitating rotation of the crankshaft.

In some embodiments of the present disclosure, a hydraulic motor of an automatic jigger is fixedly connected with a crankshaft of a compressor, and a driving shaft of the hydraulic motor and the crankshaft of the compressor do not need to be disengaged or disengaged when the compressor is in a stop state, a jigger state and an operating state, so that the structure is simple and reliable, and complex operations such as meshing and tooth alignment, separation after starting and the like in a conventional automatic jigger process are avoided.

In some embodiments, as shown in fig. 1, the automatic jigger device 100 further includes a lubricant pump 60, wherein the lubricant pump 60 is disposed in parallel with the jigger pump 20, and the lubricant pump 60 is connected to the hydraulic motor 10 through a third oil path 33, and is configured to provide flowing lubricant when the compressor is operated, such that the lubricant flows through the hydraulic motor 10, is transferred to the bearing portion 51 through the second oil path 32, and continuously provides the bearing portion 51 with lubricant.

In some embodiments, the high pressure lubrication oil output by the jigger oil pump 20 has a first pressure, and the lubrication oil output by the lubrication oil pump 60 has a second pressure, the first pressure being much higher than the second pressure, the first pressure being, for example, more than 5 times the second pressure.

In some embodiments, the jigger oil pump 20 outputs high-pressure lubricating oil to power the hydraulic motor 10 to achieve jigger operation of the compressor, and the hydraulic motor 10 operates to provide auxiliary torque when a driving motor of the compressor is started, and reduces the driving motor starting torque, thereby reducing the starting current. After the jigger is finished, the jigger oil pump 20 stops working, the driving motor of the compressor drives the crankshaft of the compressor to rotate, so that the compressor is in a normal working state, at this time, the hydraulic motor 10 is in a following state due to the fixed connection between the hydraulic motor 10 and the crankshaft 50 of the compressor through the first coupling 41, and a certain amount of lubricating oil still needs to flow through the hydraulic motor 10, and is transmitted to the bearing part 51 through the second oil path 32. The lubricant pump 60 continuously supplies lubricant to the hydraulic motor 10 through the third oil passage 33.

In some embodiments, the automatic jigger 100 further includes a fourth oil path 34, the fourth oil path 34 is bridged across the two sides of the hydraulic motor 10, one end of the fourth oil path 34 communicates with the third oil path 33 at the first node N1, the other end of the fourth oil path 34 communicates with the second oil path 32 at the second node N2, and a pressure-bearing check valve 70 is disposed on the fourth oil path 34 so that the pressure of the lubricating oil upstream of the hydraulic motor is greater than the pressure of the lubricating oil downstream of the hydraulic motor. When the compressor is in the normal working state, the crankshaft 50 of the compressor drives the hydraulic motor 10 to rotate, the jigger oil pump 20 is in the non-working state, and the lubricant pump 60 is in the working state for outputting lubricant, so that the lubricant flows through the hydraulic motor and is transmitted to the bearing part 51 of the crankshaft 50 of the compressor, thereby ensuring the normal working of the compressor. The hydraulic motor 10 generates a certain sucking action on the lubricating oil flowing through the hydraulic motor during the driven rotation, and the pressure-bearing check valve 70 is arranged on the fourth oil path 34, so that the pressure of the lubricating oil at the upstream of the hydraulic motor is larger than that at the downstream of the hydraulic motor, and the lubricating oil in the third oil path 33 at the upstream of the hydraulic motor is prevented from being sucked up.

In some embodiments, as shown in fig. 1, the automatic jigger device 100 of the compressor further includes a pressure stabilizing valve 81, wherein the pressure stabilizing valve 81 is disposed on the fourth oil path 34 downstream of the pressure-bearing check valve 70. The pressure stabilizing valve 81 is disposed between the pressure-bearing check valve 70 and the second node N2 for providing a stable and appropriate pressure of the lubricating oil in the second oil passage 32 so as to form a reasonable oil film at the bearing and the cross-head slideway. When the pressure of the lubricating oil in the second oil passage 32 is higher than the first threshold value, the lubricating oil may leak out through the pressure stabilizing valve 81.

In some embodiments, the first oil path 31 is provided with a first check valve 71 to prevent the high-pressure oil from flowing backward in the first oil path 31, and the third oil path 33 is provided with a second check valve 72 to prevent the oil from flowing backward in the third oil path 33.

In some embodiments, the automatic jigger device 100 of a compressor further comprises a relief valve 82, wherein the relief valve 82 is disposed on the first oil path 31 and is located downstream of the first check valve 71, so as to avoid excessive pressure of the lubricating oil in the first oil path 31. When the pressure of the lubricating oil in the first oil passage 31 is higher than the second threshold value, the lubricating oil may leak out through the relief valve 82.

In some embodiments, as shown in fig. 1, the first oil passage 31 and the third oil passage 33 communicate with each other through a third node N3, the third node N3 being located upstream of the hydraulic motor 10. If the driving motor is reversed after the driving motor of the compressor is connected with the cable after the new machine is installed or overhauled, the hydraulic motor can be driven to be reversed, and in order to avoid the situation that the oil pressure of a local oil way at the upstream of the hydraulic motor is too high, the overflow valve 82 is arranged as a safety guarantee.

In some embodiments, the automated jigger apparatus 100 further comprises a lubrication oil container 90 and a recovery oil circuit. The lubrication oil container 90 provides lubrication oil to the jigger oil pump 20 and the lubrication oil pump 60, and the jigger oil pump 20 and the lubrication oil pump 60 are connected to the lubrication oil container 90, for example, through oil delivery pipes. The recovery oil passage is configured to collect the lubricating oil at the bearing 51 and recover it to the lubricating oil reservoir 90. In some embodiments, the recovery oil passage also collects lubricating oil discharged at the pressure stabilizing valve 81 and/or the relief valve 82 and recovers it into the lubricating oil reservoir 90. Thereby achieving circulation of the lubricating oil.

Fig. 2 is a schematic structural diagram of a compressor system according to some embodiments of the present disclosure, and as shown in fig. 2, some embodiments of the present disclosure further provide a compressor system including: the compressor system includes the automatic jigger apparatus 100, the compressor 300, and the driving motor 200 described in the foregoing embodiments. The compressor 300 is, for example, a diaphragm compressor. The compressor 300 includes the crankshaft 50, and the driving motor 200 is fixedly connected with the crankshaft 50 to power the operation of the compressor. Specifically, as shown in fig. 2, the drive motor 200 is fixedly connected to the crankshaft 50 using, for example, the second coupling 42.

In some embodiments, as shown in fig. 2, the second oil path 32 splits at a fourth node N4 to provide lubrication oil to each friction pair of the compressor. Specifically, the second oil passage 32 divides the first branch 321 and the second branch 322, for example, at the fourth node N4, the bearing portion 51 of the crankshaft 50 includes a first bearing portion 511 and a second bearing portion 512, the first bearing portion 511 being adjacent to the first coupling 41 on a side of the first coupling 41 away from the hydraulic motor 10, the second bearing portion 512 being adjacent to the second coupling 42 on a side of the second coupling 41 away from the driving motor 200. The first and second branches 321 and 322 transmit lubricating oil to the first and second bearing portions 511 and 512, respectively, to ensure lubrication operation of the crankshaft 50.

In some embodiments, as shown in fig. 2, the compressor 300 further includes a crankcase 330, at least a portion of the crankshaft 50 being housed in the crankcase 330. In some embodiments, the crankcase 330 may function as the lubrication reservoir 90 of FIG. 1. Specifically, the jigger oil pump 20 and the lubricant oil pump 60 are connected to the crankcase 330, for example, through oil delivery lines, and the crankcase 330 supplies lubricant oil to the jigger oil pump 20 and the lubricant oil pump 60. The crankcase 330 may directly recover the lubrication oil at the bearing 51. In some embodiments, as shown in fig. 2, the crankcase 330 may also recover the lubrication oil discharged at the pressure stabilizing valve 81 and/or the relief valve 82 through the recovery oil passage 35. The circulation of lubricating oil is realized. In some embodiments, filters may be disposed on the oil delivery lines of the jigger oil pump 20 and the lubrication oil pump 60 and the crankcase 330 to filter out impurities in the lubrication oil, so as to ensure the purity of the lubrication oil provided to the jigger oil pump 20 and the lubrication oil pump 60 by the crankcase 330.

In some embodiments, as shown in fig. 2, the compressor 300 further includes a cylinder 310 and a piston 320. The number of cylinders 310 is, for example, 2, and are provided on both sides of the crankcase 330. The number of pistons 320 corresponds to the number of cylinders 310, and is also 2, for example. At least a portion of the piston 320 is disposed in the cylinder 310. The piston 320 is connected to the crankshaft 50, for example, through a piston rod, and is driven by the crankshaft 50 to reciprocate in the cylinder 310.

In the compressor system, the automatic jigger device can provide auxiliary torque for the starting of the driving motor of the compressor, and reduce the starting torque of the driving motor, thereby reducing the starting current. The hydraulic motor of the automatic jigger is fixedly connected with the crankshaft of the compressor, and the driving shaft of the hydraulic motor and the crankshaft of the compressor do not need to be separated or disengaged when the compressor is in a stop state, a jigger state and an operating state, so that the automatic jigger is simple and reliable in structure, and complex operations of meshing, tooth alignment, separation after starting and the like in the conventional jigger process are avoided.

In some embodiments, as shown in fig. 2, when the compressor starts up in a stopped state and needs to turn on the turning oil pump 20, the turning oil pump 20 outputs high-pressure lubricating oil, and the high-pressure lubricating oil is transmitted to the hydraulic motor 10 through the first oil path 31 to power the hydraulic motor 10. The hydraulic motor outputs torque to drive the crankshaft 50 of the compressor to rotate to effect turning. The lubricating oil flows through the hydraulic motor 10 and is then transferred from the second oil passage 32 to the bearing portion 51 of the compressor crankshaft 50, thereby ensuring lubrication operation of the compressor crankshaft 50. In some embodiments, the lubricating oil flowing through the hydraulic motor 10 is transferred to the first bearing portion 511 and the second bearing portion 512 via the first branch 321 and the second branch 322, respectively.

The hydraulic motor can also play a role in assisting the starting of the compressor, after the turning oil pump is started, when the crankshaft starts to rotate or the pressure of lubricating oil entering the motor reaches a rated value, the driving motor 200 of the compressor is started, and the driving motor 200 and the hydraulic motor 10 simultaneously output torque to the crankshaft 50 of the compressor, so that the compressor is started to enter a normal working state. The hydraulic motor 10 provides an assist torque for the start of the drive motor of the compressor, and reduces the start torque of the drive motor 200, thereby reducing the start current. In some embodiments, the start-up interval of the jigger oil pump 20 and the drive motor 200 is, for example, 1-200 seconds, specifically, for example, 30 seconds, 60 seconds, 120 seconds, etc.

When the compressor is normally operated, the driving motor 200 is kept operating, the turning oil pump 20 is turned off, the compressor crankshaft 50 is rotated by the driving motor 200, and the hydraulic motor 10 is in a driven state. The driven state of the hydraulic motor also causes the flow of the lubricating oil in the first oil passage 31 and the second oil passage 32 from the upstream to the downstream of the hydraulic motor. To ensure a circulating supply of lubricating oil, the lubricating oil pump 60 is turned on to deliver lubricating oil to the hydraulic motor 10.

In some embodiments, the opening time of the lubricant pump 60 is not limited as long as the circulation supply of the lubricant can be ensured. For example, the lubricant pump 60 may be turned on in synchronization with the turning oil pump 20 when the turning is performed, or the lubricant pump 60 may be turned on at the same time when the compressor driving motor is started.

In some embodiments, as shown in fig. 2, when the compressor is in normal operation, the lubricating oil outputted from the lubricating oil pump 60 is transferred to the hydraulic motor 10 via the third oil path 33, and the lubricating oil flows through the hydraulic motor 10 and is transferred to the bearing portion 51 of the compressor crankshaft 50 by the second oil path 32, so that the lubrication operation of the compressor crankshaft 50 is ensured. In some embodiments, the lubricating oil flowing through the hydraulic motor 10 is transferred to the first bearing portion 511 and the second bearing portion 512 via the first branch 321 and the second branch 322, respectively.

In some embodiments, the jigger oil pump 20 and the lubricant oil pump 60 are driven by motors, for example, respectively.
