Description

Technical Field

[0001] The present invention relates to the technical field of gas water heaters, and particularly relates to a method for debugging the primary air coefficient of a water heater and a primary air regulating plate structure. Background Art

[0002] For a gas water heater product with a strong drum structure as Figure 5 shown, due to the influence of the blower 11, the uniformity of the ratio of primary air and secondary air required for the combustion of different burner rows is poor. Usually, a primary air regulating plate needs to be added to adjust the amount of primary air required for the matching combustion of different burner rows, that is, the primary air coefficient. A common primary air regulating plate is as Figure 4 shown. The primary air injection holes 12 corresponding to each burner row are different, and need to be adjusted according to the characteristics of the burner row and the actual combustion state. This adjustment process is not successful at one time, and it is necessary to repeatedly adjust the sizes of the injection holes of each burner row to achieve the best combustion state of each burner row. However, the problem is that the primary air injection holes 12 need to be adjusted repeatedly, that is, it is necessary to repeatedly make samples and test, which wastes time and cost, is inconvenient to adjust, and has a poor adjustment effect.

[0003] In addition, experienced performance engineers usually roughly draw a sketch of a primary air regulating plate through experience, make a prototype primary air regulating plate, and then block the sizes of each primary air injection hole 12 with aluminum foil paper to achieve the purpose of adjusting the primary air injection amount. Then, through simulation calculation of the sizes and shapes of each hole, a secondary sample of the primary air regulating plate is made to shorten the time and cost of performance debugging. However, the shape of the aluminum foil blockage cannot be guaranteed to be exactly the same as the shape of the re-sampled one, that is, the performance parameters of the re-sampled sample are inevitably different from the performance parameters of the aluminum foil blockage.

[0004] Therefore, it is necessary to make further improvements. Summary of the Invention

[0005] The purpose of the present invention is to provide a method for debugging the primary air coefficient of a water heater and a primary air regulating plate structure with simple structure, convenient adjustment, low cost, high adjustment efficiency and strong practicability, so as to overcome the deficiencies of the prior art.

[0006] A method for debugging the primary air coefficient of a water heater designed according to this purpose is characterized by including the following steps: 1). Making a primary air regulating plate frame with a plurality of air injection holes; 2). Making a plurality of adjusting rings with different inner hole sizes and shapes; 3). Placing the adjusting ring in the air injection hole of the primary air regulating plate frame; 4). Observe the flame height and shape of each burner, and adjust the inner diameter of the adjustment hole of the corresponding adjustment ring for each burner one by one. Repeatedly replace the adjustment rings to achieve the best flame height and combustion performance for each burner, and form the final shape and size of the adjustment hole corresponding to each burner.

[0007] It also includes step 5). According to the final confirmed shape and size of the adjustment hole corresponding to each burner, obtain the shape and size of the actual air injection hole of the primary air adjustment plate, and directly confirm the drawing and mold opening of the primary air adjustment plate.

[0008] In step 1), the shape of the air injection hole is enlarged proportionally according to the shape of the injection hole of the corresponding burner.

[0009] A primary air adjustment plate structure designed for this purpose is used to execute the method for debugging the primary air coefficient of the water heater. It is characterized in that it includes a primary air adjustment plate frame and a plurality of adjustment rings. A plurality of air injection holes are provided on the primary air adjustment plate frame, and the air injection holes correspond one by one to the injection holes of the burner single piece. An adjustment hole is provided on the adjustment ring, and the shape and size of the adjustment holes of each adjustment ring are different. Each adjustment ring can be replaceably placed on each air injection hole to adjust the shape and size of the actual air injection hole of the primary air adjustment plate through the adjustment hole.

[0010] The outer dimension of the adjustment ring is the same as the shape and size of the air injection hole.

[0011] The shape and size of each air injection hole on the primary air adjustment plate frame are the same.

[0012] The outer dimensions of each adjustment ring are the same.

[0013] The shape and size of the air injection hole are larger than the shape and size of the injection hole of the burner single piece.

[0014] The outer dimension of the adjustment ring is larger than the shape and size of the injection hole of the burner single piece.

[0015] Each adjustment ring can be arbitrarily placed in all the air injection holes of the primary air adjustment plate frame.

[0016] The present invention makes the primary air regulating plate frame and the regulating ring, then places the regulating ring in the air injection holes of the primary air regulating plate frame, adjusts the inner diameter of the regulating holes corresponding to each burner one by one, and repeatedly replaces the regulating ring to achieve the optimal flame height and combustion performance of each burner, forming the shape and size of the regulating inner holes corresponding to each burner, so as to directly confirm the drawing and mold opening of the primary air regulating plate. The above adjustment method does not require repeated proofing tests, making the primary air regulation very convenient and fast. Moreover, the effect of the primary air regulating plate after final mold opening is exactly the same as the effect of the implementation test, making the flame height and combustion performance of each burner almost exactly the same as the performance of the debugged prototype, and saving time and cost.

[0022] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0023] See Figures 1-3 , the method for debugging the primary air coefficient of this (gas) water heater includes the following steps: 1). Make a primary air regulating plate frame 2 with multiple air injection holes 1. Each air injection hole 1 is exactly the same, and the outer dimension of the air injection hole 1 is slightly larger than the outer dimension of the injection hole on a single burner piece, so as to facilitate a certain burner to achieve the maximum primary air demand; 2). Make multiple regulating rings 4 with different inner diameters and shapes of the regulating holes 3. The outer dimensions of these regulating rings 4 are exactly the same as the outer dimensions of the air injection holes 1, that is, these regulating rings 4 can be placed in each air injection hole 1 seamlessly to achieve the purpose of changing the size of the injection hole; 3). Place the regulating ring 4 in the air injection hole 1 of the primary air regulating plate frame 2; 4), Carefully observe the flame height and shape of each burner, and adjust the size of the adjustment inner hole 3 of the corresponding adjustment ring 4 for each burner one by one. Repeatedly replace the adjustment ring 4 to achieve the best flame height and combustion performance for each burner, and form the final shape and size of the adjustment inner hole 3 corresponding to each burner. Assume the result is as Figure 2 shown.

[0024] It also includes step 5): According to the shape and size of the adjustment inner hole 3 corresponding to each burner finally confirmed, obtain the shape and size of the actual air injection hole 6 of the primary air adjustment plate 5, directly confirm the drawing and mold opening of the primary air adjustment plate 5. The primary air adjustment plate 5 after mold opening is almost exactly the same as the primary air adjustment plate corresponding to the experiment, and the flame height and combustion performance of each burner are also almost exactly the same as those of the debugged prototype. The primary air adjustment plate 5 after mold opening is as Figure 3 shown, which completely solves the problems of time waste and cost waste in repeated debugging.

[0025] In step 1), the shape of the air injection hole 1 is enlarged proportionally according to the shape of the injection hole of the corresponding burner.

[0026] This primary air adjustment plate structure is used to execute the method for debugging the primary air coefficient of this water heater, and includes a primary air adjustment plate frame 2 and multiple adjustment rings 4. Multiple air injection holes 1 are provided on the primary air adjustment plate frame 1, and the air injection holes 1 correspond one by one to the injection holes of the burner single piece. The adjustment ring 4 is provided with an adjustment inner hole 3, and the shape and size of the adjustment inner hole 3 of each adjustment ring 4 are different from each other.

The effect of the primary air adjustment plate 5 after final mold opening is exactly the same as the effect of the implementation test.

All the corresponding air injection holes 1 on the primary air adjustment plate frame 2 are designed with the same shape and size. The air injection hole 1 is usually enlarged proportionally according to the shape of the injection hole of the corresponding burner. At the same time, similar ring-shaped adjustment rings 4 with different shapes and sizes of the adjustment inner hole 3 are made. The outer shape dimensions of these adjustment rings 4 are required to be made according to the shape and size of the air injection hole 1 on the primary air adjustment plate frame 2, and the adjustment inner hole 3 is made with different shapes and sizes according to needs; these adjustment rings 4 are used to adjust the size of the actual air injection hole 6 of each burner, that is, to adjust the flame height and combustion performance of each burner.

[0028] The outer shape dimensions of the adjustment ring 4 are the same as the shape and size of the air injection hole 1. Even if they are different in shape and size, it is only positive and negative tolerances. Different adjustment rings 4 can be arbitrarily placed in all the air injection holes 1 of the primary air adjustment plate frame 2, and the gap is very small.

[0029] The shape and size of each air injection hole 1 on the primary air regulating plate frame 2 are the same.
