渣漿泵軸承體調(diào)整的方法
滑動(dòng)軸承體必須有調(diào)整機(jī)構(gòu)，在泵行業(yè)通常采用以下三種方法:
(1)在軸承體上調(diào)整在軸承體 上調(diào)整如圖5-43a所示。在軸承體上部?jī)蓚?cè)與軸承架連接螺栓處鉆垂直及水平螺孔，用4個(gè)螺釘(GB/T85- -1988) 來調(diào)整軸承體上下及左右位置。
(2) 在軸承架(托架) 上調(diào)整在軸承架上調(diào)整如圖5-43b所示。在泵軸承架的下半圓法蘭上與軸承體止口處，同樣用3個(gè)或4個(gè)方頭長(zhǎng)圓柱端緊定螺釘(GB/T85- -1988) 來調(diào)整軸承體，水平調(diào)整兩側(cè)各一個(gè)， 垂直調(diào)整在其下部一一般為一個(gè)，有時(shí)用兩個(gè)。
(3)在整體軸承體上調(diào)整 當(dāng)軸承架與軸承體合為體時(shí)， 此時(shí)仍叫軸承體，
右端。其大法蘭(往往是半圓或超過半圓)與密封體(或其他件)照樣要調(diào)整。其調(diào)整方法設(shè)計(jì)成上述(1)或(2)的形式均可。
調(diào)整軸承體實(shí)際上是調(diào)整泵轉(zhuǎn)子相對(duì)于泵中心的位置。調(diào)整螺釘上的背帽必須擰緊，直到鉆完定位錐銷孔及裝上錐銷(應(yīng)一側(cè)一個(gè))，該背帽也必須一直保留擰緊的狀態(tài)出廠。
Adjustment method of bearing body of slurry pump
The sliding bearing body must have an adjustment mechanism, and the following three methods are usually used in the pump industry:
(1) Adjust on the bearing body. Adjust on the bearing body as shown in figure 5-43a. Drill vertical and horizontal screw holes at the connecting bolts between the upper two sides of the bearing body and the bearing frame, and use four screws (gb/t85--1988) to adjust the upper, lower, left and right positions of the bearing body.
(2) Adjust on the bearing frame (bracket), as shown in figure 5-43b. On the lower semicircular flange of the pump bearing frame and the seam of the bearing body, also use three or four square head long cylindrical end set screws (gb/t85--1988) to adjust the bearing body, one on both sides of the horizontal adjustment, and one on the lower part of the vertical adjustment, usually one, sometimes two.
(3) Adjust on the integral bearing body. When the bearing frame and the bearing body are combined into a body, it is still called the bearing body at this time,
Right end. The large flange (often semicircle or more than semicircle) and the sealing body (or other parts) should also be adjusted. The adjustment method can be designed in the form of (1) or (2) above.
Adjusting the bearing body is actually adjusting the position of the pump rotor relative to the pump center. The back cap on the adjusting screw must be tightened until the positioning taper pin hole is drilled and the taper pin (one on one side) is installed. The back cap must also be kept in the tightened state and leave the factory.
