Description
Technical Field
The present invention relates to a housing assembly, and more particularly, to a housing assembly of a water ring vacuum pump.
Background
Typically, a water Ring Pump (Liquid Ring Pump) is composed of a rotating impeller with a plurality of blades and a cylinder. At this time, the impeller eccentrically rotates in the cylinder, and at this time, the liquid in the cylinder is rotated together with the rotating impeller by the rotating impeller, thereby forming a water film ring in the cylinder. That is, when the liquid in the cylinder eccentrically rotates by the rotation of the impeller, a crescent-shaped negative pressure region is formed between the impeller and the water film ring, and suction force is generated by the negative pressure region. The water ring pump is mainly used for water diversion of the pump or used as a vacuum water supply pump for sucking condensed water in vacuum sources or steam of various vacuum devices.
Specifically, the impeller is rotated in a state that a proper amount of liquid is put into a circular casing of the water ring type vacuum pump, a water film ring of a certain thickness is formed on the inner wall of the casing by the action of centrifugal force of large mass of water, and the volume of a cavity formed by the inner wall of the water film ring thus formed and the impeller blades is changed according to the rotation position, and the gas is compressed similarly to the action of a piston. Due to this effect, the gas is introduced through the gas inlet port formed in the inner wall of the circular housing and is discharged through the gas outlet port formed in the inner wall of the circular housing. In addition, the water film ring formed at this time also serves as a sealing ring (Packing ring) so that the gas introduced through the gas inlet is discharged only through the gas outlet.
For example, in a conventional water ring vacuum pump, an impeller mounted on a motor shaft of a driving motor is provided in a cylinder covered by a rear housing on a rear face, a suction port and a discharge port are integrally formed, and a partition plate is provided between a front housing provided with a suction chamber and a discharge chamber in a partitioned manner and the cylinder. As another form, a suction pipe and a discharge pipe are integrally formed on both sides of the upper portion, a suction port is formed on one side of a front housing communicating with the partitioned internal suction chamber and discharge chamber, respectively, a partition plate forming a plurality of discharge ports is installed on the other side of the front housing, a rear housing is fitted on one side of the partition plate, and is provided in combination with the front housing, wherein a shaft-coupled impeller is rotatably built in the rear housing.
Such a water ring vacuum pump is manufactured to have a large capacity and thus is mainly manufactured to have a high weight in order to secure a sufficient capacity. In addition, a water ring vacuum pump is generally installed inside the housing so as to be spaced apart from the outside to be protected.
Therefore, in the maintenance of such a high-weight vacuum pump, the maintenance is performed by taking out the high-weight vacuum pump from the housing. However, the removal of the vacuum pump of such a weight from the housing causes a risk of operator injury, safety accident, or the like.
Accordingly, in the related art, such maintenance work is mainly performed using heavy equipment, whereby there are problems such as poor working environment, cumbersome maintenance work, and increased maintenance costs.

< first embodiment >
Referring to fig. 1 to 5, the receiving assembly of the water ring vacuum pump of the present invention is provided such that the moving plate 20 can be protruded from the inside to the outside of the housing part 10. At this time, the pump body 30 is mounted on the moving plate 20.
Specifically, in order to ensure portability, a transfer wheel 12 is mounted at the lower portion of the housing 10. A pair of Mounting slots (Mounting slots) 13 are formed in the bottom plate 11 of the housing 10 along the moving direction of the moving plate 20.
In addition, a pair of auxiliary wheels 40 are mounted on the lower surface of the moving plate 20. That is, in a state where the moving plate 20 to which the pump body 30 is mounted is protruded, the auxiliary wheel 40 prevents the sagging of the moving plate 20 while smoothly supporting and guiding the movement of the moving plate 20. At this time, the auxiliary wheel 40 and the transfer wheel 12 are mounted at the same height as possible, so that the side load applied to the variable guide rail portion 50 at the time of transfer of the moving plate 20 mounted with the weight-level pump body 30 is reduced as much as possible. Here, the variable guide rail portion 50 will be described in more detail below.
Further, a pair of auxiliary wheel mounting grooves 16 are formed in the bottom plate 11 of the housing portion 10, so that the auxiliary wheels 40 can be positioned in the auxiliary wheel mounting grooves 16 when the moving plate 20 is inserted into the housing 10 (i.e., in a vacuum pump storage state).
On the other hand, both sides of the moving plate 20 are provided with variable guide rail portions 50 for extending the moving plate 20 into and out of the housing portion 10. Further, a pair of mounting slots 23 are formed in the lower surface of the moving plate 20.
Meanwhile, rod-shaped buffer members 60 (60 a, 60b; refer to fig. 7 and 8) may be inserted into mounting slots 23 formed on the base plate 11 and the moving plate 20, respectively.
Referring to fig. 6, when the pump body 30 is operated in a state where the pump body 30 is housed in the housing portion 10 (i.e., a housed state of the water ring vacuum pump), a vibration force thereof is transmitted to the moving plate 20, causing the moving plate 20 to generate considerable vibration on the bottom plate 11. Accordingly, considerable vibration and noise are generated, and in particular, abrasion of the variable guide rail portion 50 is caused, not only reducing durability of the device, but also causing a problem in that it is difficult to accommodate and extend the pump body 30.
In order to reduce vibration and noise of the pump body 30 during operation, at least one of the bottom plate 11 and the moving plate 20 of the housing 10 is provided with a mounting slot 13 or 23, and a rod-shaped buffer member 60 is interposed between the mounting slot 13 or 23 to provide a buffer effect between the moving plate 20 and the bottom plate 11.
Referring to fig. 7 and 8, as such a buffer structure, mounting grooves 21a, 21b are formed at regular intervals on the moving plate 20, and a rod-shaped buffer member 60 is inserted into the mounting grooves 21a, 21b to separate the moving plate 20 and the bottom plate 11 at regular intervals, and plays a role of buffering up-down and left-right vibrations at the time of operation of the pump body 30. That is, the plurality of mounting grooves 21a, 21b also have a function of preventing the buffer member 60 from moving left and right when vibration occurs.
The height adjustment bars 12a and 12b are provided on the transfer wheel 12 attached to the lower portion of the housing 10, and the height of the housing 10 can be appropriately adjusted according to circumstances.
Referring to fig. 9, as another form of the buffer structure, the moving plate 20 is formed with a plurality of fixing grooves 21a, 21b, and the base plate 11 is formed with a plurality of fixing grooves 11a, 11b. That is, fixing grooves 11a, 11b and 21a, 21b are formed on the moving plate 20 and the base plate 11, respectively, and the buffer members 60a, 60b may be installed therebetween. Therefore, when vibration generated during operation of the pump body 30 is reduced by the buffer members 60a, 60b, the right-and-left movement of the buffer members 60a, 60b can be reliably supported.
As described above, in fig. 9, the fixed grooves 11a, 11b and 21a, 21b are formed on the moving plate 20 and the bottom plate 11, respectively, so that the right and left movement of the buffer members 60a, 60b can be reliably prevented.
On the other hand, as shown in fig. 10 and 11, a rectangular rod-shaped buffer member (e.g., 60 in fig. 7 and 8) may be replaced with an oval buffer member 60c, and then the shape of the fixing groove 12c or 11c may be set in an arc shape. Specifically, fig. 10 (a) shows that the moving plate 20 and the bottom plate 11 are provided with arc-shaped fixing grooves 12c and 11c, respectively.
As shown in fig. 10 (b), a fixing groove 11c is formed only in the bottom plate 11. That is, the fixing grooves (21 c and 11 c) may be formed on both the base plate 11 and the moving plate 20, as shown in fig. 10 (a), or the fixing groove 11c may be formed only on the base plate 11, as shown in fig. 10 (b), as needed.
In addition, as shown in fig. 12, a pair of fixing steps 11d,11e are formed extending on the base plate 11, and this structure can place the cushioning member 60 therebetween.
On the other hand, referring to fig. 1 and 6, the housing part 10 has an inner space enough to accommodate the pump body 30. In addition, the housing portion 10 is illustrated as a parallelepiped, but may have various shapes. In addition, one side of the housing portion 10 is configured in an open form. At this time, a bottom plate 11 extending downward and contacting the ground is provided on the bottom surface of the housing part 10. At this time, although not shown in the drawings, a separate opening and closing cover (not shown) may be installed at the opened side to perform opening and closing.
In addition, the moving plates 20 are disposed close to each other in the height direction of the bottom plate 11. Therefore, the moving plate 20 can move from the base plate 11 in a state of approaching the ground. This is to minimize deformation caused by bending stress applied to the variable guide rail portion 50 by a load when the pump body 30 of high weight is moved. That is, the moving plate 20 moves at a height as close to the ground as possible, so that the local load applied to the variable guide rail portion 50 can be reduced. The auxiliary wheel 40 is preferably installed at the front end side of the moving plate 20 in order to avoid sagging of the variable load guide rail part 50 due to the pump body 30 when the moving plate 20 is extended. Smooth movement performance can be ensured.
The present invention having such a structure can easily extend the pump body 30 stored in the housing portion 10 by the moving plate 20 at the time of maintenance, thereby performing maintenance work. Therefore, it is possible to prevent problems caused by the existing crane or the like when lifting and moving the pump body 30 of the weight. In addition, since it is not necessary to disassemble or reassemble the pipe or the fixture as in the prior art during the movement of the pump body 30, the work efficiency can be improved.
The moving plate 20 of the present invention moves close to the ground (low gravity center movement), and the auxiliary wheel 40 is disposed at the front end, so that the bending load acting on the variable guide rail portion 50 is reinforced. Therefore, the problem of deformation of the variable guide rail portion 50 due to the load when the moving plate 20 moves can be prevented.
In addition, in the present invention, in a state where the pump body 30 is housed in the housing portion 10, vibration generated when the pump is operated is reduced by the buffer member 60 located on the moving plate 20 and the bottom plate 11, thereby improving operation noise and improving malfunction or wear caused by vibration during long-term use.
< second embodiment >
Referring to fig. 13 to 18, a housing assembly of a water ring vacuum pump according to another embodiment of the present invention includes: a housing portion 10 having a bottom plate 11; a moving plate 20 which can be protruded from the inside of the housing part 10 to the outside; and a pump body 30 mounted on the moving plate 20.
Specifically, the housing portion 10 has an inner space sufficient to accommodate the pump body 30. In addition, the housing portion 10 is illustrated as a parallelepiped, but may have various shapes. In addition, one side of the housing portion 10 is configured in an open form. At this time, a bottom plate 11 extending downward and contacting the ground is provided on the bottom surface of the housing part 10. At this time, although not shown in the drawings, a separate opening and closing cover (not shown) may be installed at the opened side to perform opening and closing.
On the other hand, the variable guide parts 50 are respectively installed at both sides of the inner wall of the bottom plate 11, and the front ends of the variable guide parts 50 are fixed at both sides of the moving plate 20. Therefore, the moving plate 20 can be moved in the horizontal direction from the bottom plate 11.
In addition, the moving plates 20 are disposed close to each other in the height direction of the bottom plate 11. Therefore, the moving plate 20 can move from the base plate 11 in a state of approaching the ground. This is to minimize deformation caused by bending stress applied to the variable guide rail portion 50 by a load when the pump body 30 of high weight is moved. That is, the moving plate 20 moves at a height as close to the ground as possible, so that the local load applied to the variable guide rail portion 50 can be reduced. The auxiliary wheel 40 is preferably installed at the front end side of the moving plate 20 in order to avoid sagging of the variable load guide rail part 50 due to the pump body 30 when the moving plate 20 is extended. Smooth movement performance can be ensured.
In addition, the moving wheels 12 are respectively installed at corners of the bottom surface of the housing part 10. Therefore, the housing 10 can be moved in a state where the pump body 30 is housed, and smooth mobility can be ensured.
The variable guide rail portion 50 includes: a bottom rail 53 mounted on the inner wall of the bottom plate 11 of the housing part 10; a middle rail 52 slidably mounted on the bottom rail 53; and a front end rail 51 slidably mounted on the intermediate rail 52. At this time, guide blades 51a, 52a, 53a (refer to fig. 15) are formed on the respective guide rails 51, 52, 53 to prevent the guide rails 51, 52, 53 from being bent or damaged by an impact of an external force. As shown in fig. 13, a stopper (stopper) 56 is formed on the side surface of the front rail 51, and a stopper 57 is provided on the front end of the intermediate rail 52 to limit the movement range of the front rail 51 on the intermediate rail 52.
The variable guide rail portions 50 are attached to the a region and the B region, respectively (see fig. 14). That is, the variable guide portions 50 are provided at both inner sides of the base plate 11, respectively, to prevent the eccentric load from being received when the moving plate 20 moves.
In addition, the auxiliary wheel 40 is provided with a folding column 40a folded forward at a right angle (or more than a right angle as the case may be) from the lower portion of the moving plate. Therefore, when the moving plate 20 is projected from the base plate 11, the auxiliary wheel 40 is converted into a right angle so that it can contact the ground, and when the moving plate 20 is projected toward the base plate 11 in the storage state, the auxiliary wheel 40 can be folded to the front side so as to facilitate storage (the auxiliary wheel is not caught at the lower portion of the base plate when being stored).
In addition, the end of the folding column 40a of the auxiliary wheel 40 includes a fixing plate 40b, and the fixing plate 40b is inserted into the first mounting part 20a formed at the bottom surface of the moving plate 20. That is, the auxiliary wheel 40 is provided in a detachable form in such a manner as to be slidably inserted into the first mounting portion 20a.
A second mounting portion 20b is formed on the lower surface of the moving plate 20, and the buffer member 60 is mounted to the mounting portion 20 b. Here, when the pump body 30 is operated in a state of being housed in the housing portion 10, the buffer member 60 can prevent vibration generated during the operation from being transmitted to the bottom plate 11 and even to the entire housing portion 10 via the moving plate 20.
That is, the first mounting portion 20a and the second mounting portion 20b are formed at the lower portion of the moving plate 20, and the extension of the moving plate 20 can be facilitated in a state where the auxiliary wheels 40 are mounted on the both side mounting portions 20a,20b, as the case may be. When the moving plate 20 is stored, the auxiliary wheel 40 is removed, and the buffer member 60 is inserted into the both side mounting portions 20a,20b, preventing vibration generated in the pump body 30 during operation from being transmitted to the bottom plate 11 via the moving plate 20. In addition, the vibration generated by the pump body 30 during operation can be prevented from being transmitted to the entire housing 10. That is, in a state where the moving plate 20 is housed in the case portion 10, the auxiliary wheel 40 is removed, and the buffer member 60 is mounted on the first mounting portion 20a and the second mounting portion 20b for buffering vibration between the moving plate 20 and the bottom plate 11.
In the present invention having such a structure, the pump body 30 in the state of being housed in the housing portion 10 is easily extended by the moving plate 20 to be operated at the time of maintenance. Therefore, problems caused when the existing pump body 30 lifts and moves the weight due to a crane or the like can be prevented. In addition, since it is not necessary to disassemble or reassemble the pipe or the fixture as in the prior art during the movement of the pump body 30, the work efficiency can be improved.
The moving plate 20 of the present invention moves close to the ground (low gravity center movement), and the auxiliary wheel 40 is disposed at the front end, so that the bending load acting on the variable guide rail portion 50 is reinforced. Therefore, the problem of deformation of the variable guide rail portion 50 due to the load when the moving plate 20 moves can be prevented.
In addition, in the present invention, in a state where the pump body 30 is housed in the housing portion 10, vibration generated when the pump is operated is reduced by the buffer member 11 located on the moving plate 20 and the bottom plate 11, thereby improving operation noise and improving malfunction or wear caused by vibration during long-term use.
While the present invention has been illustrated and described with reference to the exemplary embodiments, the present invention is not limited to the above-described embodiments, and various modifications may be made to the above-described embodiments without departing from the scope of the technical spirit of the present invention as set forth in the claims of the present invention, as will be apparent to those of ordinary skill in the art to which the present invention pertains.
