TJ型電動滾筒的功率多大？
2018-09-26
TJ型電動滾筒的功率、速度、直徑、筒寬均契合ISO規(guī)范和IEC規(guī)范，通常配KL型支座可適用于國內(nèi)外各種皮帶運輸機、料斗提升機等保送設(shè)備。為了便當(dāng)用戶，我們設(shè)計了TZ型支座，其裝置尺寸與TD75型皮帶運輸機完整相同。
電動滾筒作為獨立的閉式驅(qū)動組件，還能夠作為動力式輥子保送機、卷揚機等設(shè)備的動力源。電動滾筒與普通開式減速機相比，具有構(gòu)造緊湊、重量輕、占領(lǐng)空間小、密封性好、外形美觀、裝置便當(dāng)、維修簡單等優(yōu)點。普遍遭到廣闊用戶的歡送。
采用TJ型電動滾筒，按下列公式計算，所需求電動滾筒的電機功率。
功率的計算，在各種機械手冊中都有引薦公式，但方式不盡相同，計算結(jié)果也可能稍有出入。為了使電動滾筒的設(shè)計計算與用戶的運用請求統(tǒng)一同來，我們引薦采用下列公式計算電動滾筒所需求的功率：
式中：P—電動滾筒的軸功率（KW）
C—保送帶、軸承等處的阻力系數(shù)，數(shù)值能夠從表1中查到。
f—托輥的阻力系數(shù)f=0.025~0.030
L—保送機的電動滾筒與改向滾筒之間中心距的程度投影（m）
Gm—保送帶、托輥、改向滾筒等旋轉(zhuǎn)零件的重量，數(shù)值可從表2中查到。（kg/m）
V—帶速（m/s）
Qt—保送量（t/h）
H—保送高度（m）
B—帶寬（mm）
TJ type electric drum power, speed, diameter, tube width and fit the ISO specification and IEC specification, usually with KL support can be applied to domestic and foreign various belt conveyers, hopper lifting machine walks. For the convenience of users, we designed TZ type bearing, the device size and complete the same TD75 type belt conveyor.
Electric roller as driving component closed type independent, but also can be used as a power source of the power type roller conveyor, hoist equipment. Electric drum compared with ordinary open reducer, with compact structure, light weight, small occupied space, has the advantages of good sealing performance, beautiful appearance, convenient installation, simple repair etc.. Generally by the user's welcome.
Using TJ type electric drum, according to the following formula, motor power demand electric drum.
Power calculation, have recommended formula in various mechanical manual, but not the same, the calculation results also may be a slight discrepancy. In order to apply the design calculation and the user electric drum of the request of the same power to, we recommend using the following formula of electric drum needs:
In the formula: P - electric drum shaft power (KW)
Drag coefficient C conveyor belt, bearing, values from table 1 to check.
Drag coefficient f=0.025~0.030 f roller
Electric drum L conveyor and improve the degree of projection to the drum center distance (m) between
Gm conveyor belt, roller, direction change drum rotating parts weight values can be found in table 2. (kg/m)
V - belt speed (m/s)
Qt recommended weight (t/h)
H recommended height (m)
B bandwidth (mm)
