SN螺桿泵振動產(chǎn)生的原因和隔振方法
SN screw pump vibration and vibration isolation method
一、SN螺桿泵振動產(chǎn)生原因
A, SN screw pump vibration causes
1.由于SN螺桿泵制造工藝不過關(guān):轉(zhuǎn)子不平衡;泵與電機軸不同心;轉(zhuǎn)子與定子部分發(fā)生碰撞或磨擦;
2.由于使用時間較長,SN螺桿泵磨損老化:葉輪松動;軸承損壞或軸承間隙大;
3.SN螺桿泵入口管、葉輪內(nèi)、泵內(nèi)有雜物;SN螺桿泵與基礎(chǔ)固定不緊固,發(fā)生共振加強現(xiàn)像等;
4.SN螺桿泵工作中推進油流時,伴隨的渦流,氣蝕不可避免的會產(chǎn)生振動;
由此,我們可以得出結(jié)論:SN螺桿泵產(chǎn)生振動的原因很多,其中一些很多振動的產(chǎn)生幾呼是不可避免的。這就要求我們對于處置SN螺桿泵振動問題除對SN螺桿泵本身制造工藝進行加強,降低振動幅度外,通過給SN螺桿泵安裝橡膠隔振器、彈簧隔振器、隋性基座也成為SN螺桿泵振動控制重要方法。
1 since SN screw pump manufacturing process does not pass: the imbalance of the rotor; the pump and motor shaft misalignment; the rotor and the stator part collision or friction;
2 because of the use of longer, SN screw pump impeller wear: loose; bearing damage orlarge bearing clearance;
3.SN screw pump, impeller, pump entrance pipe inside; SN screw pump and the fixed basefastening, resonance strengthen now like etc.;
Push the oil flow in the screw pump with 4.SN, vortex, cavitation will inevitably producevibration;
Thus, we can draw the conclusion: many vibration causes the SN screw pump, which produced some vibration few call is inevitable. This requires us to deal with SN screw pumpvibration problem in addition to strengthening of SN screw pump itself manufacturing process,reduce the vibration amplitude, through to the SN screw pump installation of rubber isolator,spring vibration isolator, the Sui base has become the important method for vibration control of SN screw pump.
二、SN螺桿泵振動的控制治理:
A.加裝彈簧隔振器:
a.SN螺桿泵彈簧隔振器樣式的選擇:
一般選用自立式彈簧減振器,其優(yōu)點結(jié)構(gòu)簡單、造價較低;彈簧裸露在外,便于隨時觀察彈簧狀態(tài),對于需更換的彈簧提前處置,以避免彈簧銹蝕過度損壞時,造成SN螺桿泵突然沉降造成設(shè)備損害及管路扯斷等現(xiàn)像。
b.彈簧的選擇:
一般減振器廠家選用彈簧需滿足以下要求:彈簧直徑應(yīng)不少于其在額定負載下高度的0.8倍;彈簧須具備一定的額外行程,渦街流量計至少等于額定靜撓度的50%;彈簧的油平剛度至少是堅直鋼度的100%,以保證減振器的穩(wěn)定性。
c.彈簧減振器撓度的選擇;
通常減振器廠商所提拱的彈簧減振器額定撓度(彈簧額定壓縮量)一般為25MM(自頻率值約3-4HZ),此撓度可應(yīng)于650轉(zhuǎn)每分鐘的SN螺桿泵的隔振。當轉(zhuǎn)速低于650時,建議使用40以下?lián)隙戎畯椈筛粽衿鳌!?br />B。加裝橡膠隔振器:
橡膠隔振器之選擇:材質(zhì)一般為氯丁膠(C.R),天然膠(N.R);一般選用壓縮型橡膠減振器,對于重量較輕的SN螺桿泵,可選用剪切型橡膠減振器;
相較彈簧減振器,橡膠減振器隔振性能相對相差些。
C.加裝隋性基座:
為滿足更加嚴格的振動制標準,加裝隋性基座時,配合使用彈簧隔振器,無疑是的選擇。
隋性基座的規(guī)范:基座重量約為SN螺桿泵重量1-2倍以上;框架由槽鐵鎖固而成,其高度不少于長度的1/12,但不低于150MM,不高于300MM;長寬尺寸應(yīng)能將整個SN螺桿泵涵蓋在內(nèi),并各邊余10-15公分為宜。并且能將灣頭也涵蓋在內(nèi);內(nèi)澆灌油泥,并內(nèi)置一層鋼筋網(wǎng)于高度之三分之一處;加裝彈簧隔振器將基座與基礎(chǔ)間距至3-5公分。
Control, SN two screw pump vibration:
A. with spring vibration isolator:
A.SN screw pump spring vibration isolator style choice:
General selection of self-supporting spring shock absorber, which has the advantages ofsimple structure, low cost; spring is exposed outside, easy to observe the spring state, for thespring to be replaced early treatment, to avoid excessive damage caused by spring corrosion, SN screw pump sudden subsidence caused by equipment damage and pipelinebreak, we like.
B. choice of spring:
Common damper manufacturers choose to use spring shall meet the following requirements:spring diameter shall be not less than the rated load is 0.8 times the height of the spring must have certain travel; additional, vortex flowmeter is at least equal to the rated static deflection of 50%; spring oil horizontal stiffness is at least 100% vertical stiffness, in order to ensure thestability of the vibration damper the.
C. spring damper deflection choice;
Usually damper manufacturers the rated deflection spring shock absorber arch (rated springcompression) is generally 25MM (self frequency value of about 3-4HZ), the deflection can bethe isolation from 650 to SN per minute of the screw pump. When the speed is lower than 650, suggested using the 40 deflection spring isolator.
B. Installing the rubber vibration isolator:
Rubber isolator material selection: General chloroprene rubber (C.R), natural rubber (N.R);general selection of compression type rubber shock absorber, for the SN screw pump light weight, can choose a shear type rubber damper; compared with the spring and damper,rubber shock absorber vibration isolation performance relative phase difference.
C. install the Sui base:
Vibration system to meet the more stringent standards, with the Sui base, with spring vibration isolator, is undoubtedly the best choice. The Sui base specification: the base weightof about SN screw pump weight more than 1-2 times; frame by groove carabiners and fixing,the height is not less than the length of the 1/12, but not less than 150MM, not more than300MM; the length and width dimensions should be able to take the entire SN screw pumpcover, and each side more than 10-15 cm is appropriate. And can be the best bay headcovered in water; sludge, and built a layer of steel net in height 1/3; with spring vibration isolator interval between the base and the base to 3-5 cm.
二、SN螺桿泵振動控制治理效果:
基于SN螺桿泵設(shè)備情況,通過上述方法處理可達到85-99%以上的隔振效果,從而從根本上解決SN螺桿泵振動帶給人們生活,及工業(yè)生產(chǎn)的困擾。
Two, SN screw pump vibration control effect:
SN screw pump equipment based on the vibration isolation effect, can achieve more than 85-99% by using the method of treatment, so as to solve the vibration of SN screw pump to bring people to life fundamentally, distress and industrial production.
