DETAILED DESCRIPTION

[0041] The invention discloses a water pump device, which can reduce the vibration of the water pump, thereby reducing the impact on buildings and residents, and at the same time increasing the service life of instrument equipment. The invention also discloses a method for making a vibration isolation base and a method for installing the vibration isolation base.

[0042] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0043] The present invention discloses a water pump device, which includes a water pump 1 and a vibration isolation base 2. The water pump 1 is connected to the vibration isolation base 2, and a vibration absorber connector is provided on the side of the vibration isolation base 2. The vibration absorber connector is used to connect to the vibration absorber, and the vibration absorber is provided on the concrete foundation 3. In the present invention, the water pump 1 is installed on the vibration isolation base 2, and the vibration isolation base 2 is installed on the vibration reduction spring. The vibration generated by the water pump 1 during operation is firstly reduced by the vibration isolation base 2, and then reduced by the vibration reduction spring for a second time, and then transmitted to the concrete foundation 3. The vibration generated by the water pump 1 is transmitted to the concrete foundation 3 after two vibration reductions, so that the influence of the vibration on the concrete foundation 3 is significantly weakened, so that the influence on the building and residents is reduced. In addition, since the vibration is weakened, the influence of the vibration on the instrument equipment connected to the water pump 1 will also be weakened, thereby extending the service life of the instrument equipment.

[0044] The vibration isolation base 2 specifically includes a steel frame, a concrete block and a steel section assembly. The steel frame has a top opening, through which concrete is poured into the steel frame. The steel section assembly is composed of steel sections, and the function of the steel section assembly is to improve the structural strength of the vibration isolation base 2. The steel section assembly is horizontally arranged in the steel frame, and the edge of the steel section assembly is welded to the inner wall of the steel frame. The steel section assembly has a certain gap from the bottom of the steel frame. Preferably, the steel section assembly is set at a height of one-third of the steel section from the bottom of the steel frame. After the steel frame and the steel section assembly are welded, concrete is poured into the steel frame.

[0045] In a specific embodiment, the steel section assembly is designed to include a transverse steel section 12 and three longitudinal steel sections 11. The transverse steel section 12 is arranged along the length direction of the steel frame, and the longitudinal steel section 11 is arranged along the width direction of the steel frame. The ends of the transverse steel section 12 are welded to the wide side plates 13 of the steel frame, and the ends of the longitudinal steel section 11 are welded to the long side plates of the steel frame tube. Two of the three longitudinal steel sections 11 are side longitudinal steel sections 11, and the other is a middle longitudinal steel section 11. The side longitudinal steel section 11 is arranged close to the end of the transverse steel section 12, and the middle longitudinal steel section 11 is located between the two side longitudinal steel sections 11. The central axis of the side longitudinal steel section 11 is about 150 mm away from the wide side plates 13 of the steel frame. The water pump 1 in this embodiment is a horizontal water pump 1, and the center of gravity of the horizontal water pump 1 falls at the intersection of the transverse steel section 12 and the middle longitudinal steel section 11. In this way, the steel section assembly can effectively and stably support the water pump 1.

[0046] The water pump 1 includes a pump seat, which is connected to the vibration isolation base 2 through a ground anchor bolt 5, and the ground anchor bolt 5 is pre-buried in the concrete block of the vibration isolation base 2. Specifically, the pump seat of the water pump 1 includes a bolt seat that cooperates with the ground anchor bolt 5, and a gasket is arranged between the bolt seat and the vibration isolation base 2. The horizontality of the water pump 1 is adjusted by increasing or decreasing the number of gaskets. After the water pump 1 is leveled, the pump seat is locked on the vibration isolation base 2 by the ground anchor bolt 5. Thereafter, the ground anchor bolt 5 and the gasket are grouted for the second time on the vibration isolation base 2, and the gasket is filled and leveled. In this way, the firmness of the connection between the pump seat and the vibration isolation base 2 is ensured.

[0047] The shock absorber connector includes a side shock absorber connector 6 and a middle shock absorber connector 8. Correspondingly, the shock absorber includes a side shock absorber 7 and a middle shock absorber 9. The side shock absorber connector 6 is used to be connected to the side shock absorber 7. The middle shock absorber connector 8 is used to be connected to the middle shock absorber 9. The side shock absorbers 7 are arranged at both ends of the long side of the vibration isolation base 2, and the middle shock absorber connector 8 is arranged in the middle of the long side. That is, a total of six shock absorber connectors are arranged on the vibration isolation base 2, so six shock absorbers are required accordingly. It is estimated that the total weight of the vibration isolation base 2 and the water pump 1 exceeds 1 ton, and the use of six shock absorbers can improve the stability and effectiveness of vibration reduction.

[0048] The side damper 7 includes a first screw rod. The side damper connector 6 specifically includes a web and side plates arranged on both sides of the web, and the ends of the web and the side plates are welded to the long side plates of the steel frame. A first screw rod hole for the first screw rod to pass through is arranged on the web.

[0049] The middle shock absorber 9 has the same structure as the side shock absorber 7, including a second screw. The middle shock absorber connector 8 has the same structure as the side shock absorber connector 6, and also includes a web and two side plates. A second screw hole is provided on the web of the middle shock absorber connector 8, and the second screw hole is for the second screw to pass through. In particular, the second screw hole is an adjustment hole 10 extending along the length direction of the long side plate of the steel frame. When the vibration isolation base 2 is installed on the shock absorber, the installation position of the middle shock absorber 9 can be adjusted through the adjustment hole 10, so that the compression amount of all shock absorbers tends to be consistent, to ensure the horizontality of the vibration isolation base 2. The installation method of the vibration isolation base 2 will be introduced in detail below.

[0050] The present invention also discloses a method for manufacturing a vibration isolation base, comprising:

[0051] Get the dimensions of the vibration isolation base 2:

[0052] In order to facilitate fixed installation, the length of each side of the vibration isolation base 2 in both directions is a certain value greater than the corresponding side length of the pump seat. The certain value is the margin value, which is an empirical value. The length of the vibration isolation base 2 is the sum of the length of the pump seat and twice the margin value. The width of the vibration isolation base 2 is the sum of the width of the pump seat and twice the margin value.

[0053] In a specific embodiment, each side of the vibration isolation base 2 is slightly larger than the pump base by 200 mm in both directions. 基座 = Pump seat length L 泵 +400mm, width W of vibration isolation base 2 基座 = Pump seat width W 泵 +400mm.

[0054] The weight of the vibration isolation base 2 is a preset multiple of the water pump 1. According to experience, the preset multiple is not less than 1.5 times, so the weight of the vibration isolation base 2 G 基座 ≥1.5G 泵 The weight of the vibration isolation base 2 minus the weight of the bottom plate 14 of the steel frame and the weight of the steel assembly is divided by the density of the concrete block to obtain the volume of the concrete block. The weight of the side plate of the steel frame is negligible in this process. The length L of the vibration isolation base 2 has been obtained in the previous paragraph. 基座 and the width W of the vibration isolation base 2 基座 , then the length of the concrete block is approximately L 基座， The width of the concrete block is approximately W 基座 The height of the concrete block can be obtained by dividing the volume of the concrete block by the product of the length and width of the concrete block. This height is also the height H of the vibration isolation base 2. 基座 .

[0055] H 基座 ≥(G 基座 -G 底板14 -G 型钢 ) / ρ 混 L 基座 W 基座

[0056] Among them, G 基座 =1.5G 泵 ;

[0057] G 底板14 =L 基座 ×W 基座 ×78.6Kg / ㎡, 78.6Kg / ㎡ is the weight of the base plate 14 per square meter;

[0058] G 型钢 =(L 基座 +W 基座 ×3)×20.2Kg / m, 20.2Kg / m is the weight of the steel section per meter, 3 represents 3 longitudinal steel sections 11. G 型钢 The weight of one transverse steel section 12 and three longitudinal steel sections 11;

[0059] ρ 混 The theoretical value is 2000Kg / m 3 .

[0060] Substituting the above data into the formula:

[0061] H 基座 ≥{1.5G 水泵1 -[(L 基座 +W 基座 ×3)×20.2+L 基座 ×W 基座 ×78.6]} / 2000L 基座 W 基座 (Unit: m)

[0062] According to actual engineering experience, considering the convenience of installation, the height of the vibration isolation base 2 should not be less than 0.2m, that is, when H 基座 When the calculated result is less than 0.2m, H 基座 Take 0.2m.

[0063] Making the steel frame:

[0064] Make the bottom plate 14, the length of the bottom plate 14 is the same as the length L of the vibration isolation base 2 基座 The width of the bottom plate 14 is equal to the width of the vibration isolation base 2. 基座 Make the long side plate, the length of which is equal to the length L of the vibration isolation base 2. 基座 The height of the long side plate is equal to the height of the vibration isolation base 2 H 基座 equal.

[0065] Make a wide side plate 13, the length of the wide side plate 13 is equal to the width W of the vibration isolation base 2 基座 The height of the wide side plate 13 is equal to the height H of the vibration isolation base 2. 基座 equal.

[0066] The two long side plates and the two wide side plates 13 are welded to the bottom plate 14 to form a steel frame.

[0067] Welded steel components:

[0068] The two ends of the transverse steel 12 are respectively welded to the two wide side plates 13 of the steel frame, the two ends of the longitudinal steel 11 are respectively welded to the two long side plates of the steel frame, and the welding of the three longitudinal steels 11 is completed in sequence. Both the transverse steel 12 and the longitudinal steel 11 are 18# channel steel.

[0069] It should be noted that for some high-lift, large-flow water pumps 1, in order to improve the bearing strength of the vibration isolation base 2, a layer of grid-shaped steel bars can be configured in the steel frame of the vibration isolation base 2, and the diameter of the steel bars is not less than The spacing is 300×300mm.

[0070] Welding vibration damper connection:

[0071] After the steel frame is welded, the vibration damper connector is welded immediately. The vibration damper connector is made of 10mm thick steel plate and welded to the long side plate of the vibration isolation base 2. The vibration damper will bear the sum of the weight of the vibration isolation base 2 and the water pump 1. The sum of the weight of the vibration isolation base 2 and the water pump 1 is calculated to be more than 1 ton. Therefore, in order to increase the stability of the vibration isolation base 2 and the water pump 1 during operation, six vibration dampers are set, so six vibration damper connectors are required. Among the six vibration damper connectors, four are side vibration damper connectors 6, and the other two are middle vibration damper connectors 8. A side vibration damper connector 6 is set at both ends of the long side plate of the vibration isolation base 2, and a middle vibration damper connector 8 is set in the middle of the long side plate. The size of the side vibration damper connector 6 is 200×200×300mm (length×width×height). The size of the middle shock absorber connector 8 is 300×200×300 mm (length×width×height). An adjustment hole 10 is provided on the web of the middle shock absorber connector 8, and the installation position of the middle shock absorber can be adjusted through the adjustment hole 10 so that the compression deformation amount transmitted to each shock absorber by the vibration isolation base 2 and the water pump 1 is kept as consistent as possible.

[0072] Pre-embedded anchor bolts 5: embed the anchor bolts 5 into the steel frame to a preset depth, and weld the anchor bolts 5 to the steel component or the inner wall of the steel frame. The pre-embedded depth of the anchor bolts 5 should not be less than 2 / 3H of the height of the vibration isolation base 2. 基座 When pre-embedded, the anchor bolts 5 should be welded together with the steel components or side plates in the vibration isolation base 2 through steel bars, and each anchor bolt 5 should be fixed at no less than two places to ensure that the pre-embedded anchor bolts 5 will not deviate during concrete pouring.

[0073] Pouring concrete:

[0074] Pour concrete into the steel frame to form a concrete block. After the steel frame and steel components of the vibration isolation base 2 are completed, pour C20 concrete into the steel frame. To ensure the pouring quality, the concrete should be moisturized and maintained within 12 hours after pouring, and the watering and curing time shall not be less than 7 days.

[0075] Install water pump 1:

[0076] After the strength of the concrete poured on the vibration isolation base 2 reaches 100% and the embedded anchor bolts 5 are inspected and qualified, the pump seat of the water pump 1 can be fixed on the vibration isolation base 2 through the anchor bolts 5. A 100×100mm gasket is set between the bolt seat of the pump seat and the vibration isolation base 2. The number of gaskets at each anchor bolt 5 does not exceed three. The levelness of the water pump 1 is adjusted by increasing or decreasing the number of gaskets. After the levelness of the water pump 1 is adjusted, the anchor bolts 5 and gaskets can be grouted for the second time on the vibration isolation base 2, and the gaskets can be filled. The grade of the secondary slurry should be one grade higher than that of the foundation concrete. After the secondary slurry is cured, the vibration isolation base 2 together with the water pump 1 fixed thereon can be hoisted to the concrete foundation 3 for installation.

[0077] The present invention also discloses a method for installing a vibration isolation base 2, comprising:

[0078] S1: Mark the longitudinal center axis and the transverse center axis on the concrete foundation 3, and mark the installation position of the side vibration damper 7 on the concrete foundation 3 according to the position of the side vibration damper connector 6 on the vibration isolation base 2. It should be noted that the plane size of the concrete foundation 3 is 200 mm larger than the four sides of the vibration isolation base 2.

[0079] S2: A temporary bracket is welded on the bottom plate 14 of the vibration isolation base 2 by spot welding.

[0080] S3: hoist the vibration isolation base 2 onto the concrete foundation 3, and ensure that the longitudinal center axis and the transverse center axis of the vibration isolation base 2 coincide with the longitudinal center axis and the transverse center axis of the concrete foundation 3 respectively.

[0081] S4: Fix the side vibration damper 7 at the installation position of the side vibration damper 7 by using expansion screws.

[0082] S5: Install the side vibration damper connector 6 on the corresponding side vibration damper 7. During installation, the first screw of the side vibration damper 7 is passed through the first screw hole on the side vibration damper connector 6, and then the nut is locked. After the side vibration damper connector 6 is installed on the corresponding side vibration damper 7, the vibration isolation base 2 is positioned and connected through the four side vibration dampers 7.

[0083] S6: Since the four side vibration dampers 7 form a positioning support for the vibration isolation base 2, the temporary steel is removed.

[0084] S7: Adjust the compression of the side damper 7 so that the compression of the side damper 7 is less than the maximum compression of the side damper 7 to ensure the subsequent effective vibration reduction of the side damper 7. Adjusting the compression of the side damper 7 is a prior art, and can refer to the existing damper, which will not be described in detail here.

[0085] S8: Measure the static compression of the side vibration dampers 7 at both ends of the first long side of the vibration isolation base 2, and record the side vibration damper 7 at the end of the first long side with a larger static compression; measure the static compression of the side vibration dampers 7 at both ends of the second long side of the vibration isolation base 2, and record the side vibration damper 7 at the end of the second long side with a larger static compression; install the middle vibration damper 9 below the middle vibration damper connector 8 on the first long side of the vibration isolation base 2, and make the middle vibration damper 9 extend along the middle vibration damper connector The adjusting hole 10 of 8 is moved toward the side shock absorber 7 at the end with larger static compression on the first long side, and the middle shock absorber 9 is installed under the middle shock absorber connecting piece 8 on the second long side of the vibration isolation base 2, and the middle shock absorber 9 is moved along the adjusting hole 10 of the middle shock absorber connecting piece 8 toward the side shock absorber 7 at the end with larger static compression on the second long side, so that the compression amounts of all the side shock absorbers 7 and the middle shock absorber 9 tend to be consistent, and finally the middle shock absorber 9 is locked on the concrete foundation.

[0086] Finally, the middle shock absorber 9 is locked on the concrete foundation 3 by the expansion screw. It should be noted that the closer the middle shock absorber 9 is to the side shock absorber 7 with a larger static compression, the more obvious the sharing effect of the middle shock absorber 9 on the side shock absorber 7 will be, and the static compression of the side shock absorber 7 will gradually decrease.

[0087] The following is a specific description of the size calculation of the vibration isolation base 2, taking the design of the vibration isolation base 2 of a certain project as an example:

[0088] According to the design parameter requirements of water pump 1 of this project, water pump 1 uses WILO horizontal end-suction pump, model NL150 / 315-45 / 4. The overall weight of water pump 1 (including pump body, motor, base) is 900kg, and the size of water pump 1 pump base is 1840mm×730mm.

[0089] Each side of the vibration isolation base 2 is slightly larger than the pump base of the water pump 1 by 200mm. Based on the size of the pump base of the water pump 1, the length and width of the vibration isolation base 2 are first determined. The size of the base of the water pump 1 is 1840mm×730mm, so the size of the vibration isolation base 2 of this project is 2240mm*1130mm.

[0090] Vibration isolation base 2 weight G 基座 It is: 900Kg×1.5=1350kg.

[0091] The vibration isolation base 2 is composed of a steel frame, a steel component and a concrete block, wherein the steel is a 18# channel steel with three longitudinal and one horizontal sections.
