As shown in fig. 1-3, the invention discloses a self-lubricating packing box, which comprises a storage chamber 10, wherein a lubricating medium is stored in the storage chamber 10, the storage chamber 10 is communicated with the top of a polish rod channel in a packing box body 6, a lubricating unit 12 and a controller 14, the lubricating unit 12 is in signal connection with the controller 14, a filling instruction is stored in the controller 14, the controller 14 is enabled to periodically transmit a first signal to the lubricating unit 12, the first signal enables the lubricating unit 12 to apply a first acting force to the lubricating medium in the storage chamber 10, the first acting force enables the lubricating medium to move towards the top of the polish rod channel, and a first set amount of lubricating medium is input into the polish rod channel.
Based on the above, ① the invention injects the lubricating medium into the polish rod channel from top to bottom, which relieves the problem that the lubricating medium is difficult to reach the area above the injection port of the side part of the polish rod channel, and the lubricating medium cannot be uniformly distributed in the polish rod channel, so that the lubricating medium can be uniformly distributed between the polish rod and the packing box body 6, the sufficient lubrication between the polish rod and the packing box is realized, the abrasion between the polish rod and the packing box is reduced, ② the invention inputs sufficient lubricating medium into the polish rod channel through the cooperation of the controller 14 and the lubricating unit 12, which relieves the problem that the abrasion occurs between the packing box and the polish rod due to insufficient lubricating medium in the polish rod channel, and also reduces the problem that the lubricating medium overflows the polish rod channel and increases the lubrication cost due to excessive lubricating medium in the polish rod channel.
The self-lubrication in the self-lubricating packing box means that the controller 14 in the present invention can periodically start the lubrication unit 12 according to the filling command input by the operator, and fill the first set amount of lubrication medium into the polish rod channel. The packing box body 6 corresponds to a packing box in the prior art. The lubricating medium can be a medium which can lubricate the contact part of the packing box and the pumping polished rod, such as lubricating oil. The controller 14 may be embodied as a PC that is remotely connected to the lubrication unit 12. The controller 14 includes an input unit, which may be specifically an input panel or an input interface, for receiving instructions to modify the dosing frequency and the single dosing amount of the lubrication unit 12. The first set amount of lubrication medium means that after the volume of lubrication medium is injected into the polish rod channel, the volume of lubrication medium can sufficiently lubricate the polish rod and the packing box body 6, and cannot overflow from the polish rod channel.
The lubrication unit 12 of the present invention has various arrangements. For example, the self-lubricating packing box comprises a sealing unit arranged at the storage chamber 10 and used for guaranteeing the sealing performance of the storage chamber 10, the sealing unit can be a sealing ring arranged at the inlet or the outlet of the storage chamber 10, the lubricating unit 12 comprises a first shell 102, a cavity is arranged in the first shell 102, a first inlet and a first outlet which are communicated with the cavity are arranged on the first shell 102, the first inlet is communicated with a first medium source, the first outlet is communicated with the storage chamber 10, a first one-way sealing unit is arranged at the first inlet, the sealing direction of the first one-way sealing unit is arranged in a direction away from the cavity from the direction close to the cavity, a second one-way sealing unit is arranged at the first outlet, the sealing direction of the second one-way sealing unit is arranged in a direction away from the cavity from the direction close to the cavity, the driving assembly is used for conveying a second set amount of first medium into the cavity under the external acting force, the driving assembly is used for applying a first acting force to the first medium, the first acting force is used for enabling a third set amount of first medium to enter the storage chamber 10, the first acting force is used for enabling the first medium to be set into the first medium to be independent, and the first acting force is arranged for enabling the first medium to enter the first medium to be self-lubricating into the storage chamber 10, and the first acting force is set to be arranged for lubricating the first medium. The self-lubricating packing box being in the priming state means that the priming command causes the controller 14 to send a first signal to the lubricating unit 12. The first housing 102 is not limited to the cylindrical housing 3, and other shapes of the housing 3 such as a rectangular parallelepiped may be adopted as long as the arrangement of the first housing 102 does not affect the implementation of other functions herein.
According to the invention, the first medium which is arranged independently of the lubricating medium pushes the lubricating medium towards the direction of the polish rod channel, so that the problems that the lubricating medium is pushed by structures such as the pushing plate and the like, the lubricating medium is polluted by the structures such as the pushing plate and the like, and the lubricating effect is reduced are reduced.
The sealing unit ensures the tightness of the storage chamber 10, so that the lubrication medium in the storage chamber 10 is not easy to leak, the storage chamber 10 can maintain a sealing state, and the first unidirectional sealing unit and the second unidirectional sealing unit respectively ensure unidirectional sealing at the first inlet and the first outlet, so that the first medium is not easy to flow from the cavity to the outside of the cavity, and the lubrication medium is not easy to flow from the storage chamber 10 to the inside of the cavity. When the lubrication unit 12 includes a drive assembly, a first signal is sent to the drive assembly, which is activated such that the drive assembly applies a first force to a second set amount of a first medium, which in turn applies the first force to the lubrication medium, thereby inputting the first set amount of lubrication medium into the polish rod channel.
The first medium source may in particular be a device capable of actively or passively providing the first medium into the cavity. The first medium being independent of the lubricating medium means that the first medium does not destroy the lubricating function of the lubricating medium between the packing box body 6 and the polished pumping rod. The first medium can be gas which does not react with the lubricating medium, such as nitrogen, or liquid which does not damage the lubricating function of the lubricating medium, or even a gas-liquid mixture which does not damage the lubricating function of the lubricating medium can be selected as the first medium if the working condition is required, and the gas type, the liquid type or the gas-liquid mixture type of the first medium is specifically selected according to the working condition requirement.
The three values are not necessarily the same, but are affected by the sealed state of the first housing 102 and the reservoir 10, and the viscosity of the first medium and the lubricating medium, among the first set amount of the lubricating medium, the second set amount of the first medium, the second set amount of the second set amount, and the third set amount of the first medium. For example, if the viscosity of the first medium and the lubricant is not considered and the sealing state between the first housing 102 and the storage chamber 10 is good, at this time, since the first housing 102 has good sealing property, the first medium inputted into the cavity does not overflow the cavity and can completely enter the storage chamber 10, and the third set amount is the same as the second set amount in value, and the storage chamber 10 has good sealing property, so that the first set amount and the second set amount are the same in value, conversely, if the sealing property of the first housing 102 is poor, when the first medium is pushed in the direction of the storage chamber 10, part of the first medium may leak from the cavity, at this time, the first medium larger than the third set amount needs to be inputted into the cavity, and at this time, the second set amount is larger than the third set amount.
When the first medium source constitutes the drive assembly, the first medium source is a device that actively provides a first medium into the cavity, at which point the controller 14 sends a first signal to the first medium source that applies a first force to the lubrication medium such that a third set amount of the first medium enters the reservoir 10.
