Description

Technical Field

[0001] This utility model relates to the field of training device technology, specifically a water pump center alignment simulation training device. Background Technology

[0002] A centering simulation training device is a device used for training and practicing centering skills, and is commonly used in fields such as machining, equipment installation and maintenance.

[0003] In power generation, water pumps are indispensable key equipment for the normal operation of power plants. Their stable operation is directly related to the power plant's production efficiency and equipment safety. There are generally more than 100 water pumps used in a power plant, and the maintenance cycle is about one to two years. It takes two years to train a group of people who can independently perform center adjustment work, which leads to the inability to conduct timely training. At the same time, the training site is generally located in the water pump working area of ​​the power plant, which leads to uncertain safety risks during the training process. Utility Model Content

This results in untimely personnel training, and the training venue is generally located in the water pump working area of ​​the power plant, leading to uncertain safety risks during the training process.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] This utility model provides a technical solution: a water pump center alignment simulation training device. Please refer to [link / reference]. Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 It includes a support frame 1, and workbenches 2 are installed on both sides of the upper surface of the support frame 1;

[0027] The water pump housing 3 is located on the upper surface of the workbench 2. The pump shaft output end of the water pump housing 3 is equipped with a claw coupling 4. The inner side of the claw coupling 4 is provided with an opening 8. The surface of the claw coupling 4 is a circular surface 9.

[0028] A magnetic gauge base 5 is set on the surface of the pump shaft of the water pump housing 3, and a dial indicator 51 is installed on the surface of the magnetic gauge base 5.

[0029] Two dial indicators 51 are set up on the circular surface 9 and the opening 8 respectively. The indicators are divided into four points, each with a 90-degree angle. The rotor is rotated twice, and the values ​​of the opening 8 and the circular surface 9 are recorded. Taking the opening 8 as an example, the sum of the four values ​​and the result divided by four is the center value of the opening 8. By adding a pad and adjusting the water pump, the value can be made closer to the center value. The closer it is to the center value, the better the water pump will be, which improves the work efficiency and can speed up the training of personnel.

[0030] By mounting the water pump housing 3 on the workbench 2, the training device can be easily moved, allowing it to be transported to a relatively safe indoor or outdoor location for training, thus avoiding uncertain safety risks during the training process.

[0031] The bottom two sides of the water pump housing 3 are equipped with bases 6, and the upper surface of the bases 6 is screwed with anchor bolts 7. The bases 6 can be installed by means of the anchor bolts 7, thereby enabling the water pump housing 3 to be installed.

[0032] The upper surface of the base 6 is equipped with a support block 10. The upper surface of the support block 10 is provided with an arc-shaped groove. The support block 10 is welded to the water pump housing 3, so as to stably support the water pump housing 3.

[0033] Each base 6 has a mounting pad 11 at its bottom. The mounting pads 11 are all elastically designed, and the height of the water pump can be adjusted by using the mounting pads 11 so that the water pump value is close to the center value.

[0034] The base 6 and the mounting pad 11 are both provided with first threaded holes 12. The upper surface of the workbench 2 is provided with second threaded holes 13 at the corresponding positions of the first threaded holes 12. The anchor bolts 7 pass through the first threaded holes 12 and are screwed into the interior of the second threaded holes 13, so that the base 6 can be installed on the surface of the workbench 2.

[0035] Two magnetic bases 5 and a dial indicator 51 are mounted on the circular surface 9 and end face of the coupling wheel. The coupling wheel is divided into four equal parts, each at 90°. The coupling wheel is rotated two revolutions, and the values ​​on the end face and circular surface 9 are recorded. The vertical and horizontal openings 8 of the water pump are determined by calculation using a formula. By adjusting the anchor bolts 7, the above centering process is repeated until the center position of the water pump is determined.

[0036] First, install dial indicators 51 at both ends of the coupling. Generally, radial dial indicators 51 are used to measure radial deviation. Then, rotate the two half-couplings together and record the dial indicator 51 readings every 90° of rotation. Record them as a1, a2, a3, a4 radial and b1, b2, b3, b4 axial.

[0037] 2. Radial Deviation Calculation

[0038] Vertical radial deviation: Δy = a1 - a3 / 2

[0039] Left and right radial deviation: △x = a2 - a4 / 2

[0040] 3. Radial Deviation Calculation

[0041] Vertical axial deviation: △By=b1—b3 / 2

[0042] Vertical axial deviation: △Bx = b2 - b4 / 2

[0043] 4. Adjustment Calculation

[0044] If there is a shaft spacing L1 and a coupling diameter D between the couplings, in the vertical direction, the adjustment amount of the front support is c1y = △y × L1 / D, and the adjustment amount of the rear support is c2y = △y × L1 + L2 / D; the same applies in the horizontal direction.

[0045] After developing this platform, we started by training personnel, shortening the training cycle from the original two years to the current three months, thus accelerating the formation of combat effectiveness; the on-site simulation analysis of water pump failures effectively improves maintenance quality and efficiency, and accumulates troubleshooting experience; the more flexible site configuration eliminates the need for fixed-location teaching, making teaching more convenient; and the platform offers higher safety.

[0046] When this solution is in operation: First, two dial gauges 51 are set up on the circular surface 9 and the opening 8 respectively. The gauges are divided into four points, each with a 90-degree angle. The rotor is rotated twice, and the values ​​of the opening 8 and the circular surface 9 are recorded. Taking the opening 8 as an example, the sum of the four values ​​and the result divided by four is the center value of the opening 8. The water pump can be adjusted by adding pads to bring the value closer to the center value. The closer the value is to the center value, the better the water pump effect will be. By mounting the water pump housing 3 on the workbench 2, the training device can be easily moved, allowing it to be transported to a relatively safe indoor or outdoor location for training, thus avoiding uncertain safety risks during the training process.
