Description

Technical Field

[0001] The utility model relates to the technical field of centrifugal pump detection, in particular to a special installation size detection device for a centrifugal pump. Background Art

[0002] A wall-mounted boiler usually refers to a device that burns gas, converts the chemical energy in it into heat energy and transfers it to water, turning the water into hot water with a certain pressure and temperature. It has multiple safety protection measures such as anti-freeze protection, anti-dry burning protection, accidental flameout protection, over-temperature protection, and water pump anti-stuck protection. Therefore, it has been widely used in people's daily lives.

[0003] However, the interfaces of the internal pump structures of current wall-mounted boiler systems are sometimes not standard and have complex structures. Some interface mating surfaces are not regular planes but curved surfaces, which results in some special installation dimensions being difficult to measure or impossible to measure with measuring instruments. As a result, in actual production, precise adaptation tests may not be performed to ensure production efficiency, which ultimately leads to the risk of mismatch during the assembly of the overall equipment, resulting in defective products. Utility Model Content

DETAILED DESCRIPTION

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments.

[0024] See also Figure 1-7 A centrifugal pump special installation dimension detection device comprises a centrifugal pump 1, a water outlet interface mounted on the centrifugal pump 1, and a detection device 2, wherein the water outlet interface comprises a T-shaped assembly hole 1001, an upper boss 1002, and a lower boss 1003, wherein the T-shaped assembly hole 1001 is arranged on the inner side of the middle part of the water outlet interface, the upper boss 1002 and the lower boss 1003 are respectively fixedly connected to the front end top and the front end bottom of the water outlet interface, a side surface of one side of the upper boss 1002 is set as a first limiting surface 1004, and a side surface of the other side of the lower boss 1003 is set as a second limiting surface 1005;

[0025] The front end surface of the upper boss 1002 is coplanar with the front end surface of the lower boss 1003, the top surface of the second detection set block 2003 is coplanar with the bottom surface of the first detection set block 2002 and forms an assembly angle with the horizontal plane, and the assembly angle is set to 15 degrees;

[0026] The top inner wall of the first detection set block 2002 and the bottom inner wall of the second detection set block 2003 are both provided with standard surfaces 2005, thereby limiting the stroke of assembly detection, and the front end corner structure at the bottom of the first detection set block 2002 and the front end corner structure at the top of the second detection set block 2003 are both provided with detection sharp corners 2006. After the detection assembly is completed, the detection sharp corners 2006 will be connected with the corresponding surface of the upper boss 1002 or the surface of the lower boss 1003 for intuitive observation and detection by the inspector;

[0027] The detection device 2 includes a docking truncated platform 2001, a first detection set block 2002, a second detection set block 2003 and a knob plate 2004. The first detection set block 2002 and the second detection set block 2003 are respectively fixedly connected to the surfaces on both sides of the docking truncated platform 2001. The rear end of the knob plate 2004 is fixedly installed on the surface of the front end of the docking truncated platform 2001. The docking truncated platform 2001 can be assembled with the front end of the T-shaped assembly hole 1001, and the first detection set block 2002 is synchronously driven to engage with the lower boss 1003 for detection, and the second detection set block 2003 is engaged with the upper boss 1002 for detection during rotation adjustment.

[0028] The diameter value of the docking truncated table 2001 is the same as the diameter value inside the front end of the T-shaped assembly hole 1001, which ensures the connection effect after the snap-fit ​​assembly, and the docking truncated table 2001 can be in the snap-fit ​​state with the T-shaped assembly hole 1001, and the end face of the rear end of the docking truncated table 2001 fits and connects with the inner wall of the step in the middle of the T-shaped assembly hole 1001, which improves stability. The inner wall of the first detection set block 2002 and the inner wall of the second detection set block 2003 are coated with a wear-resistant coating to improve the wear-resistant use effect of the structure, thereby creating good conditions for subsequent sustainable use. The surface of the knob plate 2004 is provided with an anti-slip groove to increase friction.

[0029] Working principle: When in use, the docking truncated platform 2001 is snap-fitted to the inner side of the front end of the T-shaped assembly hole 1001, and the end face of the rear end of the docking truncated platform 2001 is fitted and connected with the inner wall of the step in the middle of the T-shaped assembly hole 1001, and at this time, the first detection set 2002 and the second detection set 2003 are in a cross arrangement with the upper boss 1002 and the lower boss 1003;

[0030] Next, the knob plate 2004 is rotated clockwise, so that the docking truncated table 2001 synchronously drives the first detection set block 2002 and the second detection set block 2003 to rotate synchronously, until the standard surface 2005 set on the second detection set block 2003 is fitted and connected with the first limit surface 1004 set on the upper boss 1002, and at the same time, the standard surface 2005 set on the first detection set block 2002 is also just fitted and connected with the second limit surface 1005 set on the lower boss 1003. If this process is achieved normally, it means that the appearance size of the water outlet interface is basically qualified. On the contrary, if any one of the standard surfaces 2005 cannot be assembled with the corresponding structure, it means that the appearance size of the water outlet interface is unqualified and needs to be repaired.

[0031] After the first detection block 2002 and the second detection block 2003 are assembled on the water outlet interface, the detection sharp corner 2006 provided on the second detection block 2003 will fit with the surface of the corresponding position of the upper boss 1002. Similarly, the detection sharp corner 2006 provided on the first detection block 2002 will fit with the surface of the corresponding position of the lower boss 1003. The gap after the two detection sharp corners 2006 are connected is observed. If there is no obvious gap space, it means that the appearance size of the water outlet interface is completely qualified. On the contrary, if there is an obvious gap space after any one of the detection sharp corners 2006 is assembled with the corresponding structure, it means that the appearance size of the water outlet interface is qualified and needs to be repaired.

[0032] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
