水泵減震器選型和安裝需要注意什麼What should be paid attention to in the selection and installation of water pump shock absorber

    很多人都知道水泵，水泵機械經常用在城市供水，汙水處理，農業水利工程，石油工業傍邊，人們的日子離不開水泵，水泵除了裏邊葉輪，泵軸幾個首要的當地需求保護之外，水泵在裝置時還需求用到減震器設備。減震器在水泵運行時起重要效果。那麼減震器使用對水泵有什麼作用呢?

Many people know that water pumps and pump machinery aRE often used in urban water supply, sewage treatment, agricultural water conservancy projects, and oil industry. People can not live without pumps. Besides the impeller and shaft inside, the pump also needs shock absorber equipment when it is installed. Shock absorber plays an important role in pump operation. So what is the effect of shock absorber on water pump?

    減震器在水泵中起到操控噪音，避免振動的效果。一般的水泵減震器使用的大概有這幾種：低頻複合橡膠減振器、阻尼彈簧減振器、橡膠剪切隔振器。那麼水泵減震器該如何安裝呢，水泵減震器安裝要注意什麼?

Shock absorber in the pump to control noise, avoid vibration effect. The general shock absorber of water pump uses these kinds: low frequency compound rubber shock absorber, damping spring shock absorber and rubber shear isolator. So how to install the shock absorber of water pump? What should we pay attention to when installing the shock absorber of water pump?

    水泵減震器安裝中應注意的事項：

Matters needing attention in the installation of water pump shock absorber:

1、減震器應按泵組中心軸對稱布置。橡膠墊的平面布置可以是順時針或逆時針。

1. The shock absorber shall be arranged symmetrically according to the central axis of the pump unit. The layout of rubber pad can be clockwise or anticlockwise.

2、當機組減震器采用六個支撐點時，其中四個支撐點布置在惰性塊或型鋼框架的四角，另外兩個支撐點應設置在長邊線上，並調整其位置，以保持壓縮變形。減震器的操作應盡可能一緻。

2. When six support points are used for the shock absorber of the unit, four of them are arranged at the four corners of the inert block or steel frame, and the other two shall be set on the long side line, and their positions shall be adjusted to maintain the compression deformation. The operation of the shock absorber should be as consistent as possible.

3、臥式泵機組安裝橡膠墊或阻尼彈簧減振器時，不需要將橡膠墊和阻尼彈簧減振器與地面、惰塊或鋼架粘結或固定。

3. When the rubber pad or damping spring damper is installed on the horizontal pump unit, it is not necessary to bond or fix the rubber pad and damping spring damper with the ground, the idler block or the steel frame.

4、立式抽油機減震安裝采用橡膠減振器時，建議在抽油機底座下安裝型鋼框架，采用錨定安裝，型鋼框架與橡膠減振器之間采用螺栓（帶彈簧墊圈）。地上或地板上設有接地螺栓，橡膠減震器通過接地螺栓固定在地面或地板上。

4. When the rubber damper is used in the vibration absorption installation of the vertical pumping unit, it is recommended to install the steel frame under the base of the pumping unit and adopt the anchoring installation. The bolt (with spring washer) is used between the steel frame and the rubber shock absorber. The ground bolt is set on the ground or the floor, and the rubber shock absorber is fixed on the ground or floor through the grounding bolt.

5、橡膠墊邊緣不應超過惰性塊邊緣，型鋼框架的支撐面積不應小於阻尼元件頂部的支撐面積。

5. The edge of the rubber pad should not exceed the edge of the inert block, and the support area of the steel frame should not be less than that of the top of the damping element.

6、當單層橡膠墊層的頻率比不能滿足要求時，可采用多層串聯布置，但墊層數量不宜超過五層。串聯橡膠隔離墊的型號、塊數、面積、硬度應相同。

6. When the frequency ratio of single layer rubber cushion can not meet the requirements, multi-layer series arrangement can be adopted, but the number of cushion should not exceed five layers. The model, number, area and hardness of rubber isolation pads in series shall be the same.

7、襯墊和鋼板應采用粘合劑粘合。鍍鋅鋼板的平面尺寸應比橡膠墊的兩端大10 mm。與鍍鋅鋼板上下層粘結的橡膠墊應錯開。

7. Gaskets and plates shall be bonded with adhesive. The plane dimension of galvanized steel sheet shall be 10 mm larger than both ends of rubber pad. The rubber pads bonded with the upper and lower layers of galvanized steel sheet shall be staggered.

8、施工安裝前應及時檢查。安裝時，減震器的靜態壓縮變形不應超過***允許值。

8. Check in time before construction and installation. During installation, the static compression deformation of the shock absorber shall not exceed the maximum allowable value.

9、泵組安裝時，要求泵組的支撐地面平整，並有足夠的承載力。

9. When the pump unit is installed, the support ground of the pump unit is required to be flat and have sufficient bearing capacity.

10、單元減震器應避免接觸酸、堿和有機溶劑。

10. Avoid contact with organic solvents, acids and solvents.
