SN螺杆泵振动产生的原因和隔振方法
SN screw pump vibration and vibration isolation method
一、SN螺杆泵振动产生原因
A, SN screw pump vibration causes
1.由于SN螺杆泵制造工艺不过关：转子不平衡;泵与电机轴不同心;转子与定子部分发生碰撞或磨擦;
2.由于使用时间较长，SN螺杆泵磨损老化：叶轮松动;轴承损坏或轴承间隙大;
3.SN螺杆泵入口管、叶轮内、泵内有杂物;SN螺杆泵与基础固定不紧固，发生共振加强现像等;
4.SN螺杆泵工作中推进油流时，伴随的涡流，气蚀不可避免的会产生振动;
由此，我们可以得出结论：SN螺杆泵产生振动的原因很多，其中一些很多振动的产生几呼是不可避免的。这就要求我们对于处置SN螺杆泵振动问题除对SN螺杆泵本身制造工艺进行加强，降低振动幅度外，通过给SN螺杆泵安装橡胶隔振器、弹簧隔振器、隋性基座也成为SN螺杆泵振动控制重要方法。
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螺杆泵振动的控制治理：
A.加装弹簧隔振器：
a.SN螺杆泵弹簧隔振器样式的选择：
一般选用自立式弹簧减振器，其优点结构简单、造价较低;弹簧裸露在外，便于随时观察弹簧状态，对于需更换的弹簧提前处置，以避免弹簧锈蚀过度损坏时，造成SN螺杆泵突然沉降造成设备损害及管路扯断等现像。
b.弹簧的选择：
一般减振器厂家选用弹簧需满足以下要求：弹簧直径应不少于其在额定负载下高度的0.8倍;弹簧须具备一定的额外行程，涡街流量计至少等于额定静挠度的50%;弹簧的油平刚度至少是坚直钢度的100%，以保证减振器的稳定性。
c.弹簧减振器挠度的选择;
通常减振器厂商所提拱的弹簧减振器额定挠度（弹簧额定压缩量）一般为25MM（自频率值约3-4HZ），此挠度可应于650转每分钟的SN螺杆泵的隔振。当转速低于650时，建议使用40以下挠度之弹簧隔振器。
B。加装橡胶隔振器：
橡胶隔振器之选择：材质一般为氯丁胶（C.R），天然胶（N.R）;一般选用压缩型橡胶减振器，对于重量较轻的SN螺杆泵，可选用剪切型橡胶减振器;
相较弹簧减振器，橡胶减振器隔振性能相对相差些。
C.加装隋性基座：
为满足更加严格的振动制标准，加装隋性基座时，配合使用弹簧隔振器，无疑是的选择。
隋性基座的规范：基座重量约为SN螺杆泵重量1-2倍以上;框架由槽铁锁固而成，其高度不少于长度的1/12，但不低于150MM，不高于300MM;长宽尺寸应能将整个SN螺杆泵涵盖在内，并各边余10-15公分为宜。并且能将湾头也涵盖在内;内浇灌油泥，并内置一层钢筋网于高度之三分之一处;加装弹簧隔振器将基座与基础间距至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螺杆泵振动控制治理效果：
基于SN螺杆泵设备情况，通过上述方法处理可达到85-99%以上的隔振效果，从而从根本上解决SN螺杆泵振动带给人们生活，及工业生产的困扰。
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.
