DHP环链电动葫芦可以单独使用，也可以安装在起重设备上组合配套工作，如果操作人员使用方法不当，DHP环链电动葫芦在作业中可能会遇到一些问题。那么，下面为大家分析DHP环链电动葫芦作业中可能遇到的情况，帮助大家更好的解决问题： 　　1.电源问题，如缺相、接触不良、电路损坏、电压过低等，由电工检修之后即可正常通电。 　　2.声音问题，如控制回路异常声音、电机噪声等，要由技术维修人员判断接触器或轴承、联轴器、齿轮等具体部位，对症下药。 　　3.制动问题，如制动不灵或刹车过死，原因在于制动器内部零件损坏，需要及时换新。对于群吊电动葫芦我们并不陌生，它是一种低速环链电动葫芦，一种轻小起重机械，它具有起吊速度慢，机体质量轻，机件硬度高，磨损小的特点。群吊电动葫芦保留了手拉葫芦轻巧方便的特点,又改进了手拉葫芦人工操作,提升速度慢不足,它集电动葫芦和手拉葫芦的优点与一身,采用盘式制动电机做工作。那么如果群吊电动葫芦变形了，比如说：凹陷了，我们应该怎么办？ 　　首先我们需要搭建检修平台，检查群吊电动葫芦的损坏情况，其中的一些部件是否需要更换，然后根据一些具体的数据，调整现场，高强度构件在修理现场一般选择丝杠比较方便将丝杠放置于卷筒和外壳凹陷处间距的边缘，点动群吊电动葫芦控制手柄按钮，使卷筒逆时针转动，并逐渐送进丝杠，在卷筒的力矩作用下挤压丝杠，丝杠压迫外壳凹陷处，迫使凹陷处复原，待全部复原后，卷筒顺时针转动，退出丝杠。然后就测试是否运转正常，就可以工作，群吊电动葫芦产品“可退换说明”用户在购买群吊电动葫芦时会签订一份具有法律效力的购销合同，基本事宜参照合同处理，如遇群吊电动葫芦产品不合预期的情况下，我们提供一定的退换货服务。 DHP were studied.the optimum processing chain electric hoist can be used alone, also can be installed on the hoisting equipment form a complete set of combination work, if the operation personnel use undeserved, DHP were studied.the optimum processing chain electric hoist may encounter some problems in the operation. So, the following analysis for everybody DHP were studied.the optimum processing chain electric hoist assignments that may be encountered in case, to help you better solve problems: 1. The power supply problem, such as lack of phase, poor contact, damage of circuit, voltage too low, by the electrical maintenance after normal can electricity. 2. The problem of sound, such as abnormal sound of control circuit, the motor noise, etc., to the technical maintenance personnel judgment contactor or bearing, coupling, gear, such as the site, suit the remedy to the case. Or 3. The braking problems, such as brake block, brake die due to brake the internal parts damaged, need to change new in time. For group of crane electric hoist we are not strange, it is a kind of low speed chain electric hoist, a small light lifting machinery, it is lifting slowly, the body weight, high hardness, wear small features. Group of crane electric hoist to keep his hand chain hoist and convenient features, and improve the hand chain hoist manual operation, lack of speed is slow, it combines the advantages of electric hoist and chain with a suit, the disc brake motor work. So if the group of crane electric hoist deformation, such as: depression, what should we do? First of all we need to establish the platform maintenance, inspection group of crane electric hoist damage, whether some of these parts need to be replaced, and then according to some concrete data, adjust the scene and high strength components at the scene of the repair generally choose the screw is more convenient to screw placed on the edge of the drum and the shell cavity spacing, point DongQun crane electric hoist control handle button, make the drum counterclockwise rotation, and gradually to the screw, the roll torque under the action of extrusion screw, screw compression shell cavity, forcing cavity recovery, after being full recovery, drum clockwise rotation, from the screw. Then test whether working properly, it can be work, group of crane electric hoist products "can return instructions" users when they pinpointed crane electric hoist and sign a legally binding contract, basic issues with reference to the contract processing, in case of crane electric hoist products under the condition of not expected, we provide a certain amount of return service.
