Description

Technical Field

[0001] The utility model relates to an outer cylinder support reinforcement structure, and specifically to an outer cylinder support reinforcement structure for a long-axis vertical pump, which can solve the problem of vibration caused by the operation of a long-axis vertical pump that is too long, and transmits the vibration load to a concrete foundation through a support structure, thereby greatly improving the stability of the long-axis vertical pump and reducing damage to wearing parts, thereby extending the service life of the water pump and further increasing the service life of the water pump. Background Art

[0002] As the name suggests, long-axis vertical pumps generally have long shafts, and the length of the pumps can even reach 40 to 50 meters. However, as long-axis vertical pumps become longer and longer, their stability becomes worse and worse. Therefore, it is difficult for the current long-axis vertical pump industry to ensure the safe and stable operation of long-axis vertical pumps during use. Through the overhaul of faulty water pumps, it was found that the problems mainly focused on the following four points: First, the guide bearings and wear-resistant rings of the wearing parts are seriously worn, or even worn out; second, the shaft system is seriously worn, especially the sleeve. When the water pumps in many projects were disassembled for overhaul, it was found that the sleeve had disappeared, and then the shaft was worn, twisted, or even broken; third, the outer body was broken as a whole or the flange position was partially broken; fourth, the outer body, wearing parts fasteners, installation base fasteners, etc. were sheared, fell off, loosened, etc. to varying degrees.

[0003] At present, there is no special and reliable solution for manufacturers to deal with the longer and longer water pumps. The commonly used solution is to improve the processing and manufacturing accuracy, ensure the concentricity of the long-axis vertical pump itself, and at the same time improve the installation accuracy to ensure the concentricity of the equipment and the foundation installation. However, this cannot fundamentally solve the adverse effects of the longer and longer long-axis vertical pumps, and can only extend the maintenance time. As the wearing parts of the water pump are worn out during use, the shaft system will swing and vibrate more in the cylinder. At this time, the shaft system of the rotor component will collide with and wear the stator component cylinder, and other adverse phenomena will occur. This load is loaded on the outer cylinder of the stator. Because the shaft system is very long, it is equivalent to a long torque, which will amplify this load, and then drive the outer cylinder to vibrate and swing. Once the stator components begin to vibrate and swing, it is fatal to the equipment, which will cause rapid wear of the guide bearings and wear-resistant rings, and rapid wear of the sleeves, causing the shaft system to bend and break. Over time, under the action of vibration and fatigue stress, the fastening bolts of the outer cylinder will be loosened, fall off, or even sheared, and the outer cylinder will tear, causing fatal harm to the water pump. In order to completely solve the problem of increasingly poor stability of long-axis vertical pumps as the pumps become longer and longer, and to ensure the safe and stable operation of long-axis vertical pumps, it is of great significance to support and reinforce the outer cylinder.

[0026] The preferred embodiments of the present invention are given below in conjunction with the accompanying drawings to illustrate the technical solution of the present invention in detail.

[0027] Figure 1 This is the main view of the schematic diagram of the structure of the utility model. Figure 2 It is a top view of the schematic diagram of the structure of the utility model. Figure 1-2 As shown: The utility model proposes an outer cylinder support reinforcement structure for a long-axis vertical pump, which includes: an embedded bracket 10, an ear handle fastener 20, an ear handle 30, an adjusting nut 40, a cylinder bracket 50, a connecting rod fastener 60, and a connecting rod 70; the ear handle 30 and the connecting rod 70 both have a steering function, and the ear handle 30 and the connecting rod 70 are connected to have a length-adjustable ear handle 30 and a connecting rod 70, and the above components include four sets to support four angles.

[0028] The ear handle and the embedded bracket are connected by an ear handle fastener, and the ear handle is an ear handle with a steering function. The ear handle and the connecting rod are connected by a double adjusting nut, and the double adjusting nut is a double adjusting nut with the ability to adjust the axial length; the connecting rod is connected to the cylinder bracket by a connecting rod fastener, and the connecting rod is a connecting rod with a steering function; the embedded bracket 10 is partially cast in the concrete partition wall; the ear handle fastener 20 is located between the ear handle and the embedded bracket, and fixedly connects the ear handle 30 and the embedded bracket 10; the ear handle 30 is connected to the embedded bracket 10 through the ear handle fastener 20, in the part where the embedded bracket 10 and the ear handle are nested; the double adjusting nut 40 is made of high-strength stainless steel, and the double adjusting nuts 40 are respectively located on both sides of the connecting rod through which the ear handle passes, and the double adjusting nut 40 is a double adjusting nut 40 that adjusts the axial connection size of the ear handle and the connecting rod by adjusting the position of the double nut, thereby realizing the function of adjusting the axial size of the support device.

[0029] The cylinder bracket 50 is welded together with the outer cylinder of the long-axis vertical pump; the connecting rod fastener 60 connects the connecting rod 70 and the cylinder bracket 50, one end of the connecting rod 70 is connected to the ear handle 30, and the other end is embedded in the cylinder bracket and fixed by the connecting rod fastener 60.

[0030] Figure 3 This is a schematic diagram of the structure of the joint of the embedded bracket, the ear handle fastener and the ear handle of the utility model. Figure 3As shown: a set of embedded brackets 10 includes a parallel part parallel to a set of partition walls and two sets of vertical parts perpendicular to the partition walls. The parallel part of the embedded bracket 10 is cast into the concrete partition wall at one time according to the design size when the concrete partition wall is cast, and is welded and anchored to the steel bars in the concrete. The ear handle 30 is located between the two sets of vertical parts and is fixed between the two sets of vertical parts by fixing parts. There is a gap between the ear handle 30 and the vertical part to allow the ear handle 30 to have a steering function.

[0031] The cylinder support 50 is formed by welding together with the outer cylinder of the long-axis vertical pump, and the welding position is heat-treated to eliminate welding stress.

[0032] One end of the connecting rod 70 is connected to the ear handle, and the other end is embedded in the cylinder bracket. The size of the cylinder bracket is larger than the size of the connecting rod in the part where the connecting rod and the cylinder bracket are embedded. Therefore, the connecting rod embedded in the cylinder bracket can freely turn within a certain range in the cylinder bracket.

[0033] In the specific implementation process, the ear handle fastener 20 is a fastener made of high-strength stainless steel. In the illustrations given in the present utility model, the ear handle fastener 20 is a fastener composed of a screw and a nut.

[0034] like Figure 1 Main view and Figure 2 As shown in the top view: the embedded bracket 10 is poured into the concrete partition wall at one time according to the designed size when the concrete partition wall is poured, and is welded and anchored to the steel bars in the concrete at the same time, so as to ensure the reliability between the partition wall and the embedded bracket. The ear handle fastener 20 is made of high-strength stainless steel to ensure the reliability of the connection between the ear handle and the embedded bracket. The ear handle 30 is connected to the embedded bracket through the ear handle fastener. In the part where the embedded bracket and the ear handle are nested, the size of the embedded bracket is larger than the size of the ear handle. Therefore, the ear handle nested in the embedded bracket can be freely turned within a certain range in the embedded bracket, so that the support device has a steering function. The double adjustment nut 40 is made of high-strength stainless steel. The double adjustment nuts are respectively located on both sides of the ear handle passing through the connecting rod. By adjusting the position of the double nuts, the axial connection size of the ear handle and the connecting rod can be adjusted (see Figure 4 ), thereby realizing the function of adjusting the axial size of the supporting device. The cylinder bracket 50 is welded together with the outer cylinder of the long-axis vertical pump, and the welding position is heat treated to eliminate welding stress. At the same time, the weld is inspected to ensure the welding quality, thereby ensuring the reliability between the cylinder bracket and the cylinder. The connecting rod fastener 60 is made of high-strength stainless steel to ensure the reliability of the connection between the connecting rod and the cylinder bracket. One end of the connecting rod 70 is connected to the ear handle, and the other end is embedded in the cylinder bracket. The size of the cylinder bracket is larger than the size of the connecting rod in the part where the connecting rod and the cylinder bracket are embedded. Therefore, the connecting rod embedded in the cylinder bracket can be freely turned within a certain range in the cylinder bracket, and has a steering function.

[0035] When the utility model is in use, the load is transferred to the connecting rod through the cylinder bracket, and then to the ear handle through the connecting rod, and finally to the concrete partition wall through the embedded bracket, thereby absorbing the undesirable load of the unit. The undesirable load is the main reason for the serious wear of the guide bearings and wear-resistant rings of the wearing parts; it is the main reason for the serious wear of the shaft system, and then the shaft wear, twisting, and even broken shaft; it is the main reason for the overall fracture of the outer body or the local tearing of the flange position; it is the main reason for the shearing, falling off, loosening, etc. of the outer body, the fasteners of the wearing parts, the installation base fasteners, etc. Therefore, the stability of the long-axis vertical pump can be improved while reducing the damage to the wearing parts, extending the use time of the water pump, and thus increasing the service life of the water pump.

[0036] When this structure is in use, in order to avoid installation problems such as eccentricity and angle differences that may occur during the installation of the embedded brackets cast into the concrete partition wall at one time and the cylinder brackets welded to the outer cylinder at one time, the ear handles and the connecting rods are designed to have steering functions, and the connection between the ear handles and the connecting rods has an adjustable length, which further eliminates the adverse effects of installation problems on the operating stability of the unit, thereby ensuring smooth, reliable and long-term operation of the unit.

[0037] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected, and the scope of protection of the utility model is defined by the attached claims and their equivalents.
