coil group or one-phase winding is reversed

The wrong connection of the motor of the elevator When a coil,Backing plateThe elevator is good, it will cause a serious imbalance in the three-phase current and cause the winding to overheat.The safety device and application of the guide rail hydraulic lifting platform The use of the guide rail hydraulic lifting platform The guide rail hydraulic lifting platform is a non-scissor hydraulic lifting freight elevator. It is used for goods between different floors of industrial plants, restaurants, restaurants, etc. The low height can be made to -mm. The advantage is that it can be placed directly on the ground without digging pits, reducing engineering construction costs, and there is no need to set up hanging points on the top, which is safe. Reliable; the hydraulic lifting platform adopts hydraulic transmission mode, and can be non-calibrated according to customer needsSeveral types: Motor winding open circuit. When one of the motor windings is disconnected, or one of the parallel branches is disconnected,Backing plateElevating cargo elevator Elevating cargo elevator, the three-phase current will be unbalanced and the motor will overheat.Backing plate,If the hydraulic valve is damaged, its effectiveness should be maintained. If it is damaged, it can be replaced in time.Frequently check the humidity of the aerial work vehicle that is prone to water accumulation. It is inevitable that the aerial work vehicle is driving in rainy and snowy weather, or on muddy roads. The bottom and some gaps and indoor floors are easy to accumulate sludge. If the owner does not clean it in time, this will hide the moisture. Therefore, the outer edge of the wheel hub, the key hole and the wiper frame and other areas should be checked regularly the corner of the bottom of the trunk, and the drainage holes in the door and various parts should be kept unblocked to ensure that the car seat covers, carpets and floors are protected from humidity. Rusty fittings.Fani,It is best not to cover the aerial work vehicle and park the vehicle outside. If it is windy and rainy, the clothing will repeatedly slap the car paint, especially if the car blows sand on the clothes, it will draw many fine scratches on it. Because it will turn black over time. In addition, when the wind does not directly spray powder or clean the sand on the mechanism, but it should be washed with water, and prevent the sand particles on the paint surface from being scratched by the vacuum cleaner.Hydraulic pump station: special pump station for domestic lifting platform, protection device outside the pump station imported from Italy: organ m type, mesh type, iron plate seal type.The motor winding is short-circuited. When a short-circuit fault occurs in the motor winding, the short-circuit current is much larger than the normal operating current, which increases the copper loss of the winding, it must be replaced immediately. The maintenance of the wire rope should be strictly in accordance with regulations.It adopts a scissor-type mechanical structure, so that the aerial work platform can still move stably when it carries a large weight and rises to a large working height. It is its larger range of high-altitude operations and carrying capacity that make it widely used in various fields. The self-propelled scissor-type aerial work platform can walk quickly or slowly at various heights during operation, and can conveniently and continuously complete operations such as forward, backward, up and down, left and right steering on the operating platform. Make high-altitude operations more efficient and more secure. Therefore, it has received more widespread attention in the market.Nowadays, small and medium-sized enterprises are holding products with the idea of ​​good quality and favorable price.Where can I find it?,Check the limit switch to see if all the limit switches are loose. If so, please tighten them. Pay special attention to the ultra-high protection stroke of the hydraulic lifting platform to avoid accidents caused by the equipment exceeding the high safety height; check the pins (ear pins and center pins) Check whether the nuts, nuts, screws, etc. are loose,Backing plateFixed guide rail type cargo elevator, if any, should be reinforced immediately; ensure that the hydraulic lifting platform rises and falls smoothly; outriggers (for high-altitude operating platform)Correct construction elevator site inspection First of all, we need to check the foundation to see if there is any water accumulation, and check whether the grounding system meets the requirements. We also need to check how the structural bolts of the frame are fastened and whether there are any cracks in the welds. We need to follow the instructions to set it up. In mechanical transmission it can be divided into two types: open type and closed type. Of course, the lift also has a lot of safety equipment.Regarding the cleanliness of the hydraulic station, is there any relevant rule requirement?

Unscrew the screw on the dust-proof hole outside the flange of the elevator, adjust the PCS system ring to align the side hole with the dust-proof hole, remove the motor shaft key.Safety and health,The parts such as reduction box, gearbox, external gear and hydraulic oil are all in accordance with the requirements in the table.The open base of the adjustment plate makes it easier to clean up debris.Low cost: The cost is much lower than that of the scissor-type mobile lifting platform, so when purchasing a lifting platform, you must consider the scope of use of the lifting platform, the frequency of work, the load and other factors to choose a lifting platform that suits the work requirements .Backing plate,When installing, dismantling and adjusting the slewing mechanism, care should be taken to ensure that the centerline of the slewing mechanism reducer is parallel to the centerline of the gear, the meshing surface is not less than % and the meshing clearance is suitable.The motor winding is short-circuited. When a short-circuit fault occurs in the motor winding, the short-circuit current is much larger than the normal operating current, causing the winding to overheat and even burn out.Walking: assisted self-propelled, two-wheel traction, self-driving, and car modified.
