供应SMH660R40E6.7W21三螺杆泵、黄山螺杆泵、高压油泵如何进行三螺杆泵配套机械密封的更换安装，必须遵循以下几点：How to replace the three screw pump mechanical seal installation, the following points must be observed:（1）螺杆泵出厂序列号、机械密封的型号、规格是否正确以及是否为带有黄山天曼泵业有限公司三螺杆泵机械密封件标识标志，质量是否符合标准；密封安装前，应确认产品型号及规格与设备要求一致。(1) the screw pump mechanical seal factory serial number, type, specification is correct and whether with Mount Huangshan teamon pump industry limited company machinery three screw pump seal logo, quality standards;seal before installation, should confirm the product types and specifications and equipment requirements.（2）静环尾部防转槽端与防转销顶部应保持1mm-2mm的轴向间隙，以免缓冲失效。(2) the static ring tail anti rotary slot end and the anti rotation pin top should maintain the axial clearance of 1mm-2mm, so as to avoid the buffer invalidation.（3）动、静环端面用酒精清洗干净，其余金属件用汽油清洗并用洁净的压缩空气吹干，仔细检查务必保证动、静环密封面没有任何损伤。损伤和破裂的均不能更换。装配前，两件“O”形橡胶密封圈应涂上机械密封标准一层润滑油膏，动、静环端面不许涂油。(3) dynamic, static ring tip with alcohol to clean, and other metal parts cleaning with gasoline and clean compssed air dryer, carefully check must ensure that the dynamic, static ring sealing surface without anydamage. Damage and can not be broken replacement. Before the assembly, the two "O" shaped rubber sealing ring should be coated with a layer of lubricating grease standard mechanical seal, dynamic, not static ring oiler.（4）在安装密封的轴，腔体及压盖等与辅助密封圈接触处均匀涂油（注：对乙丙橡胶、或介质不允许注入润滑油的情况下，可涂抹植物油或肥皂水。把机械密封套上轴，按设计的工作高度安装到位。过压盖通孔，采用对角线交叉拧紧方式，用螺栓将整个密封与密封腔体（泵盖）联接拧紧机械密封配有挂系统时，按标示正确连接管路。(4) in the installation of the sealing shaft, cavity and a gland and auxiliary seal ring contact uniform oiling (Note:ethylene propylene rubber,orthe media are not allowed into the lubrication condition, can apply vegetable oil orsoap and water. The mechanical sealing sleeve shaft, according to design the working height of the installed in place. Overvoltage cover through hole, the diagonal cross screw, bolt the entire seal and seal cavity (cover)connected tighten the mechanical seal fitted with auxiliary system, marked by the pipeline connecting the right.（5）在三螺杆泵转子与泵体的相对位置固定之后，确定机械密封的安装位置，根据密封的安装尺寸及静环在压盖中的位置，测算出密封在轴或轴套上的尺寸。(5) after the relative positions of the three screw pump rotor and pump body is fixed, to determine the installation position of mechanical seal, according to the size and position of the installation of sealing static ring in the gland,calculate the location dimension seal in the shaftorshaft sleeve.（6）安装机封动环，动环安装后须保证能其在轴上灵活移动。(6) mounted machine sealing ring, ring after installation shall ensure that its flexible move on the shaft.（7）将组装好的静环部分和动环部分组装好。(7) the assembled static ring and moving ring partially assembled.（8）把密封端盖装在密封体内，并将螺丝拧紧。(8) the sealing end cover is arranged in the sealing body, and the screw.（9）试车：以上步骤完成后，手动盘车三螺杆泵配套机械密封，注意观察转矩的变化，以及有无擦碰声音异常等，以确定是否要重新安装和调整。(9) test: after the above steps, manual turning three screw pump mechanical seal, observe the torque change,and there is no rubbing sound abnormal, to determine whether to re install and adjust.（10）打开阀门，密封腔内通入密封介质，全部排出密封腔的空气，使密封腔中全部充满介质，并观察封有无泄漏情况。(10) to open the valve, the sealing cavity communicated with the sealing medium, exhaust all the seal cavity of the air, so that the sealing cavity full of medium, and observe the seal without leakage.（11）确认上述两项正确无误后进行试运转。(11) confirmed that the above two correct test run.（12）机械密封腐蚀防护知识详解(12) the mechanical seal corrosion protection knowledge.（13）表面均匀腐蚀。如果金属环表面接触腐蚀介质，而金属本身又不耐腐蚀，就会产生表面腐蚀，其现象是泄漏、早期磨损、破坏、发声等。金属表面均匀腐蚀有成膜和无膜两种形态，无膜的金属腐蚀很危险，称为应力腐蚀破裂，选用堆焊硬质合金及铸铁、碳化钨、碳化钛等密封环，容易出现应力腐蚀破裂。腐蚀过程以一定的速度进行，使电偶腐蚀加剧。(13) surface uniform corrosion. If the metal contact ring corrosive medium, and the corrosion of the metal itself is intolerant, it will have a surface corrosion, which is leaking, the early wear and tear, damage, such as audible.Uniform corrosion on metal surfaces have two forms of film and without film, corrosion of metal membrane free is dangerous, known as stress corrosion cracking, the selection of welding hard alloy and cast iron, tungsten carbide, titanium carbide seal ring, prone to stress corrosion cracking. The corrosion process to a certain speed,so that aggravate galvanic corrosion.（14）应力腐蚀破裂。金属在腐蚀和拉应力的同时作用下，耐磨性。机械密封填充F4环的腐蚀主要是指填充的选择性腐蚀、溶出或变质破坏。如在氢氟酸中，玻璃纤维分子热腐蚀，这些裂缝沟通了整个密封端面，加速了端面的磨损，使泄漏量增加。14) the stress corrosion cracking. metal corrosion and stress at the same time, wear resistance. Corrosion of mechanical seal ring filled F4 mainly refers to the selective corrosion, filled strippingordestruction of metamorphism. Such as hydrofluoric acid, the hot corrosion of glass fiber elements, these cracks sealed face communication as a whole, to speed up the end of the wear and tear, so that leakage increased.SMH三螺杆泵的型号：SMH系列SMF系列SMS系列SME系列SM40系列三螺杆泵SMH40R38E6.7W23三螺杆泵SMF40R38E6.7W23三螺杆泵SMS40R38E6.7W23三螺杆泵SME40R38E6.7W23三螺杆泵SMH40R46E6.7W23三螺杆泵SMF40R46E6.7W23三螺杆泵SMS40R46E6.7W23三螺杆泵SME40R46E6.7W23三螺杆泵SM80系列三螺杆泵SMH80R36E6.7W23三螺杆泵SMF80R36E6.7W23三螺杆泵SMS80R36E6.7W23三螺杆泵SME80R36E6.7W23三螺杆泵SMH80R42E6.7W23三螺杆泵SMF80R42E6.7W23三螺杆泵SMS80R42E6.7W23三螺杆泵SME80R42E6.7W23三螺杆泵SMH80R46E6.7W23三螺杆泵SMF80R46E6.7W23三螺杆泵SMS80R46E6.7W23三螺杆泵SME80R46E6.7W23三螺杆泵SM120系列三螺杆泵SMH120R42E6.7W23三螺杆泵SMF120R42E6.7W23三螺杆泵SMS120R42E6.7W23三螺杆泵SM120R42E6.7W23三螺杆泵SMH120R46E6.7W23三螺杆泵SMF120R46E6.7W23三螺杆泵SMS120R46E6.7W23三螺杆泵SME120R46E6.7W23三螺杆泵SM210系列三螺杆泵SMH210R40E6.7W23三螺杆泵SMF210R40E6.7W23三螺杆泵SMS210R40E6.7W23三螺杆泵SME210R40E6.7W23三螺杆泵SMH210R46E6.7W23三螺杆泵SMF210R46E6.7W23三螺杆泵SMS210R46E6.7W23三螺杆泵SME210R46E6.7W23三螺杆泵SM280系列三螺杆泵SMH280R43E6.7W23三螺杆泵SMF280R43E6.7W23三螺杆泵SMS280R43E6.7W23三螺杆泵SME280R43E6.7W23三螺杆泵SMH280R46E6.7W23三螺杆泵SMF280R46E6.7W23三螺杆泵SMS280R46E6.7W23三螺杆泵SME280R46E6.7W23三螺杆泵SM440系列三螺杆泵SMH440R40E6.7W23三螺杆泵SMF440R40E6.7W23三螺杆泵SMS440R40E6.7W23三螺杆泵SME440R40E6.7W23三螺杆泵SMH440R46E6.7W23三螺杆泵SMF440R46E6.7W23三螺杆泵SMS440R46E6.7W23三螺杆泵SME440R46E6.7W23三螺杆泵SM660系列三螺杆泵SMH660R40E6.7W23三螺杆泵SMF660R40E6.7W23三螺杆泵SMS660R40E6.7W23三螺杆泵SME660R40E6.7W23三螺杆泵SMH660R46E6.7W23三螺杆泵SMF660R46E6.7W23三螺杆泵SMS660R46E6.7W23三螺杆泵SME660R46E6.7W23三螺杆泵SM940系列三螺杆泵SMH940R42E6.7W23三螺杆泵SMF940R42E6.7W23三螺杆泵SMS940R42E6.7W23三螺杆泵SME940R42E6.7W23三螺杆泵SMH940R46E6.7W23三螺杆泵SMF940R46E6.7W23三螺杆泵SMS940R46E6.7W23三螺杆泵SME940R46E6.7W23三螺杆泵SM1300系列三螺杆泵SMH1300R42E6.7W23三螺杆泵SMF1300R42E6.7W23三螺杆泵SMS1300R42E6.7W23三螺杆泵SME1300R42E6.7W23三螺杆泵SMH1300R46E6.7W23三螺杆泵SMF1300R46E6.7W23三螺杆泵SMS1300R46E6.7W23三螺杆泵SME1300R46E6.7W23三螺杆泵SM1700系列三螺杆泵SMH1700R42E6.7W23三螺杆泵SMF1700R42E6.7W23三螺杆泵SMS1700R42E6.7W23三螺杆泵SME1700R42E6.7W23三螺杆泵SMH1700R46E6.7W23三螺杆泵SMF1700R46E6.7W23三螺杆泵SMS1700R46E6.7W23三螺杆泵SME1700R46E6.7W23三螺杆泵SM2200系列三螺杆泵SMH2200R42E6.7W23三螺杆泵SMF2200R42E6.7W23三螺杆泵SMS2200R42E6.7W23三螺杆泵SME2200R42E6.7W23三螺杆泵SMH2200R46E6.7W23三螺杆泵SMF2200R46E6.7W23三螺杆泵SMS2200R46E6.7W23三螺杆泵SME2200R46E6.7W23三螺杆泵公司优势特色：售前服务1、专业的技术工程师为您服务，给您提供准确合适的选型组合、确保为客户选择*优性价比的产品。2、提供考察接待：我们欢迎您随时随地莅临公司现场考察，并为您提供任何便利条件。售中服务1、 无论您是国外的客户还是国内的客户，无论您是我们的老客户还是我们的新朋友，无论您的合同经额是大还是小，我们都将诚信、公平、热情、严谨地同一对待；2、提供全面的产品资料：产品参数、产品安装尺寸等。及时排产，确保交货时间准确。3、 我们保证守时、保质、保量地严格执行合同规定的各项条款，并且为客户提供超值的服务，比如产品安装、培训等等。售后服务我们建立了完善的售后服务系统，全天候24小时为您服务。1、提供产品安装指导，全天候满足您的各种需求。2、所有产品质保一年，在质保期类免费为您服务。终生以*低成本价供应产品的各类配件。专业为您提供*适合您需求的螺杆泵。1、专业的销售团队为您选择*具性价比的螺杆泵产品。2、现进的生产工艺确保为您提供优质的产品3、完善的售后服务解除您的后顾之忧4、超高的效率确保交货及时准确。欢迎广大新老客户来电咨询、订货，垂询热线：18098577778公 司 名称：黄山天曼泵业有限公司联系人姓名：程晓 先生 (销售 经理) 18098577778（TEL）办 公 地址：中国 黄山市徽州区城北工业园 邮 编：245400电 话：86-0559-7502919传 真：86-0559-2324433移 动 电话：18098577778邮 箱：Hstmby01@126.comQ Q：QQ：2282419218 阿 里 旺旺:旺旺：hstmby01公司主页：http;//www.hstmby.comhttp://www.luogb.com http://www.cntmby.comhttp://www.tm-pCompany name: Mount Huangshan teamon pump industry limited companyContact person: Mr. Cheng Xiao (Sales Manager) 18098577778 (TEL)Office address: China Huangshan City Huizhou area north of the City Industrial ParkPostal Code: 245400Tel: 86-0559-7502919Fax: 86-0559-2324433Mobile phone: 18098577778E-mail: Hstmby01@126.comQ Q: QQ:2282419218A: I want to: hstmby01Company homepage: http; //www.hstmby.comhttp://www.luogb.comhttp://www.cntmby.comhttp://www.tm-p.cc
