Only trained personnel familiar with these standards should handle these motors. Safety equipments necessary for the prevention of accidents at the installation and operating site must be provided in accordance with local regulations.The reliability of these motors may be impaired if they are used improperly, badly connected or altered / modified in any way. Such alterations / modifications are not permitted.The certificates issued apply to motors as originally supplied. In order to maintain validity, it is essential that any servicing / repair be undertaken by authorized personnel.2.Receipt, Handling and Storage:Receipt:Inspect the condition of packaging immediately upon receipt for any damages during transportation. Unpack motor carefully and inspect for any hidden damage or missing parts (not visible before unpacking) before storage. A complete visual inspection of the motor must be performed after removing the package.▲All damages must be immediately photographed, documented and reported to the transporter within 24 hours, and to the insurance company and to BBL local office,(through whom the motor is purchased), within 48 hours. This is required to maintain the time limits for filing claims. Failure to comply with this procedure will void the product warranty.•While reporting damage, please mention motor serial number.•In this case, installation must not be started, till the problem is solved.•Check if the delivery of the order is complete. (Spare parts, documents etc.)•Check the nameplate data corresponds with the application for which, the motor will be used. Makea special point of checking voltage and connection (delta or star).•Rotate the shaft by hand to check free rotation.Handling:▲Steel cables and hoisting equipment must have capacity to bear the motor weight.▲Failure to follow the following instructions, may result in the motor falling over, or slipping in the lifting tackle. The result can be death, serious damage, or material breakage.▲During lifting, mounting or maintenance work, all safety considerations shall be in place and special attention is to be taken so that nobody will be subject to lifted load.•When lifting the motor, the correct hoisting points, the weight of the motor and the operating capacity of the hoisting crane must be matched. Motors packed in wooden crates must always be lifted by their own eyebolts/lifting lugs or by a proper forklift, and must not be lifted by its wooden crates.•For lifting the motor, only the lifting eye-bolts provided with motor, are to be used. The eyebolts aredesigned for the motor weight only. Never use the eyebolts to lift the motor with additional loads, such as pumps, gear boxes, fans or any other driven equipment.•Use all lifting eye-bolts together that are provided, for sharing the load. (If motor is provided with two eye-bolts, use both eye-bolts and not one). Ensure that the eyebolts are fully tightened up to theirsupporting surface, before lifting.•The packing (wooden crate with motor) must not be dropped. It is to be carefully placed on the floorwithout impact to avoid the damage to the bearing. Jerks and jolts must be avoided.•Do not use any other part of the motor for lifting including shaft.•Do not use shaft projections for dragging the motor.•Do not roll or drag the motor on the floor.•Motors must not be kept in vertical position with external fan cowls as base.•In vertical lifting, uncontrolled rotation of the motor must be prevented. Do not lift other equipments with motor lifting points only.•During movement of the motor from one place to other place, the shaft must be locked with the locking device supplied with the motor (if any).The shaft locking device to be removed just before the installation of the motor.Storage:•Storage room must be clean, dust free and dry. The room must be properly covered and closed. •Maintain temperature in the range 20 ˚C to 50 ˚C and relative humidity to be 50% or less in the storage room.•Ensure absence of harmful fumes and vapours, gases such as chlorine, sulphur dioxide and corrosive agents.•Vibration free area to avoid bearing damage.•Motors fitted with cylindrical roller and/or angular contact bearings are supplied with locking device mounted on shaft which should be kept in place.•Factory fitted open bearings use Lithium based grease SKF LGMT3 with recommended shelf life of two years. If stored for longer period, grease needs to be replaced with same grease. Mixing of two greases should be avoided. Shielded bearings have a storage life of five years.•Space heater must be energized if temperature falls below 10˚C or humidity is more than 50% to prevent harmful effects of moisture condensation. Heaters must be isolated while motor is energized, since the heaters if energized, could cause the motor surface temperature to exceed the maximum for which it is certified. This would invalidate the certification and could result in ignition of the surroundingatmosphere. Heaters must be de-energized before opening any part of motor enclosure.•Ensure that no water dips on motor and no water accumulates under the motor.•Ensure that all plugs originally provided are in place. (e.g. cable entry hole plugs). If plugs are missing, all the openings to be covered with an adhesive plastic cloth.•Cover the motor completely in a strong, transparent plastic bag to exclude dirt, dust, moisture, and otherforeign materials. Before sealing this bag, small bags of silica-gel desiccant should be put inside the bag, around the motor.•Rodents, insects and other animals, like to house inside motors in search of warm surroundings or food.Some of them attack the insulating materials. Their access to the motor must be avoided.•Do not remove the corrosion protection from the machined surfaces like shaft and flange. These protections must remain in place until the final assembly.•Any damage to the painting or to the rust protections on the machined surfaces must be corrected.3.Installation and commissioning:Accurate and careful installation of the motor is of utmost important.▲Read the safety instructions in full before doing any activity of installation.▲Rotating parts such as pulleys, couplings and shaft extensions must be permanently guarded.▲Disconnect the power supply before working on motor or driven equipment.The nameplate gives the technical data and defines the limits of usage of the motor.•Inspect the nameplate data and ensure that the voltage and frequency correspond to the available voltage and frequency at site.•Kilowatt rating and rpm of the motor must correspond to the requirement of the driven equipment.•Motor protection, atmosphere and zone are compatible.•Ensure that the motor is not damaged.•Remove any shaft locking device and store it for future use.•Slowly rotate the shaft to ensure free rotation. Any foreign matter in the air gap must be removed.•Remove the anti corrosion agent on shaft, with petrol/white spirit/kerosene/thinner. Do not use sandpaper or scrapper.•If the storage is more than two months, check the grease condition in the bearings.•Mixing of two different greases to be avoided.•Replace the grease in the bearings if the motor has been stored for more than 18 months. This is not applicable where sealed bearings (2Z/ ZZ) are used•Ensure all covers are installed before starting installation.•Motors must be installed in such a way, that those are accessible at all times.•The area around and above the motor must be sufficient for its inspection, maintenance or handling. A person must have enough room to carry out cleaning services. This helps in periodic maintenance to be easier and easy removal of the motor from services, in case of major maintenance work.•The site must be clean and well- ventilated. If the air contains dust, moisture or corrosive gases, the motor must be appropriately protected, or otherwise supplied with clean air through pipes or ducts.•The fan covers must be cleaned at regular intervals to ensure free air circulation.•Other equipment or building wall must not block the motor ventilation. The motor must be installed, where it can get adequate ventilation and clean dry air.•The clearance between the fan cover (air inlet for motor cooling) and any wall / barrier must be minimum 50% of the air inlet diameter of the fan cover.•The cable and ducts must be arranged to facilitate the connection of cable to motor.Insulation resistance▲In order to measure the insulation resistance, the motor must be shutdown.▲The winding terminals to be grounded to remove electrostatic charges prior to test. Noncompliance may result in electric shock and personnel injuries.▲Ensure no explosive atmosphere is present while executing insulation resistance check procedure. Measure insulation resistance before commissioning and when winding dampness is suspected. If an insulation resistance observed value is lower than 10 mega ohms at 40 degree centigrade, the winding must be dried out by heating up to 130 deg. C for at least 8 hours.Thermal ProtectionWhen PTC thermistors are located in stator windings, they must be connected to a suitable control circuit, such that the motor is disconnected from the mains supply in the event of a winding reaching the temperature rating of the thermistor.4.Electrical Connections:•The connection diagram is provided in the terminal box.

2.2安装海密梯克屏蔽电泵正常运转时无振动，20kW以下的屏蔽电泵不需要加固基础和底座。
2.3管路连接1）泵的入口管路及出口管路应有支撑，以防止传递给泵额外的载荷，泵不能作为管路中的受力点。
在输送热流体时，要保证管路系统有为热膨胀而提供的补偿措施。
2）当正吸入压头较低时，入口管路应尽可能短，以防止发生汽蚀。
入口管路应有适当的尺寸以保证流体流速不超过3m/s；在输送易汽化的流体或液化气时，保证流速不超过1m/s。
3）出口管路应安装一调节阀，以调节泵的流量和扬程。
在使用较长的出口管路或两台泵并联使用时，我们推荐安装一附加的单向止逆阀。
4）整个管路系统以及辅助管路均应仔细清洗，以防止铁屑、焊渣或其它异物进入海密梯克泵中。
对于新建的管路系统，入口管路应装有过滤器。
5）管路设计应考虑到泵的排气。
6）为实现泵的连续运转，我们推荐安装一回流管路，安装最小流量孔板，以保证连续运转时滑动轴承有足够的润滑和冷却。
如图1所示，回流管路应从出口阀或单向止逆阀之前引出，通过最小流量孔板返回储液罐中。

5.主要结构简述
5.1 本系列电动机的接线盒位于电动机顶部，可4个方向进线，适用于橡套电缆（或塑料电缆）和钢管布线两种结构，接线盒可分别制成3个或6个接线端子，内设一个接地端子，并按其规格分别制成一个（M8及以下）或二个（M10及以上）的出线口。
6.防爆要点
6.1本系列电动机为隔爆型电动机，要求电动机内部的爆炸性混合物爆炸时，隔爆外壳不应
损坏或产生影响隔爆性能的变形；内部爆炸火焰不允许通过外壳的隔爆接合面引起外部爆炸性混合物的爆炸，为此：
a：组成隔爆外壳的零部件如机座、端盖、轴承内盖、接线盒盖、接线盒座等，精加工后须经1.0mpa，历时10o+2s静压试验合格；
b：链接隔爆外壳的螺栓均装有弹簧垫圈，防止自行松脱。
c：机座、端盖、轴承内盖、接线盒座、接线螺栓、端子套（或接线板）、轴、密封圈是隔爆零部件。
密封圈材质为橡胶XH-21.
6.2在额定工作状态下，电动机外壳表面温度，煤矿用不得超过+200℃，但有煤粉堆积在电
动机外表面时，不得超过+150℃。
进线口外的温度不得高于所用电缆的允许温度，以保证电缆运行可靠。
7.安装与使用
7.1安装前的装备
7.1.1电动机开箱前应检查包装箱是否完整无损。
7.1.2电动机开箱后应小心清除电动机的尘土和防锈涂封。
7.1.3电动机安装前须进行下列各项检查，如不符合要求，则不装投入使用。
a、有防爆标志和防爆合格证编号，并与电动机的使用场所要求一致；
b、隔爆外壳各零部件联接正确，紧固可靠；
c、所用隔爆零件应无裂纹和影响隔爆性能的缺陷（未拆过的新电机可不检查）；
d、轴承润滑脂注排油装置通畅；
e、定子绕组与机壳间绝缘电阻；额定电压380v时不低于0.38MΩ;额定电压660v时，
不低于0.66 MΩ；额定电压1140v时，不低于1.14 MΩ。
7.2电动机采用弹性联轴器传动，电动机与被传动的主机轴中心要保持一致，否则会引起轴
承损坏和轴断裂。
7.3电动机与电源电缆的连接。
7.3.1电源引入电缆的外径要与密封圈的孔径相符，密封圈规格见表5（可根据引入电缆
的外径大小剥去密封圈同心圆）。
配合直径差不小于1mm，当压紧接线盒斗后，应保证密封圈与电缆之间及密封圈与接线盒座之间无间隙，否则将失去隔爆性能。
表5
7.3.2引入的电缆芯线要接在两弓形垫圈之间，注意芯线的飞刺不准突出，引入电缆还须
用接线压板和弓形垫圈压紧固定，防止窜动。
7.3.3六端子接线盒通过连接片改变接法，可适用两种不同电压需要（
8. 保养与维修
8.1 电动机应定期检查和清扫，外壳不得堆积灰尘，不得用水龙头喷射清扫电机。
8.2 电动机运行时轴承允许温度不得超过95℃（温度计法），轴承每运行2500小时（约半
年）至少检查一次，如发现轴承润滑脂变质必须及时更换，更换前，须将轴承外盖、贮油盒内的费油以及排油装置的油管、油杯清理干净，并用汽油将轴承清洗干净，润滑脂采用锂基润滑脂3号（GB7324-87），加脂量2极电机为轴承室净容积的1/2,4极以上为2/3.
8.3 拆装电动机时应注意保护隔爆面。
（H63-160）机座号的电机没有轴承内外盖，轴承靠装
在端盖轴盖轴承室内的孔用圈实现轴向锁紧。
拆卸电动机时，应先拆掉轴伸端的V 型轴封环，拆去前端盖、再拆风扇端的风罩、后端盖的固定螺栓，将后端盖连同转子一起从风扇端抽出，将后端盖连同轴承孔用挡圈一起从转子上取下，去掉孔用圈即可拆除轴承。
电动机装配时，先将轴承装入后端盖轴承室，再将孔用挡圈装入端盖槽内，套到转子上，将转子装入定子内固定后端盖，再装轴伸端轴承波形弹簧片，前端盖并上固定螺栓、再装两端V 型轴封环，上好风罩，即完成电机装配。
装配时，隔爆面需涂204-1防锈脂。
8.4 电机受潮时，必须干燥处理，可采用烘干炉或短路电流法。
在干燥过程中，电机绕组温
升应逐渐升高，且不可超过155℃。
用短路电法干燥时，电机处于短路状态，其输入电流为0.6-0.8倍额定电流值为宜，严重受潮电机不宜用于直流电干燥，以免发生电解现象。
8.5 电动机损坏时，应由原制造厂进行修理，或者可能导致电动机失去隔爆性能，或电动机
某项性能恶化，以致不能使用。
