malpensa airpoSeveral types: motor winding open circuit. When one phase of the motor winding is open circuit, or one of the parallel branches is open circuit it will cause three-phase current imbalance and cause the motor to overheat.
Motor connection error. When the triangular connection motor is mistakenly connected into a star shape, and the current flowing through the stator winding exceeds the rated current, leading to the motor stopping itself. If the stopping time is slightly longer and the power supply is not cut off, the winding will not only be severely overheated, but also burned. When a star connected motor is mistakenly connected into a triangle, or when several coil groups are connected in series into a single branch, the motor is mistakenly connected into two branches in parallel, both the windings and the iron core will overheat, and in severe cases, the windings will be burned.

For parts where butter cannot be added, it is necessary to dredge the oil circuit or replace the grease fitting until butter can be added otherwise it is prohibited to use the equipment.
The cleanliness of the hydraulic station is an important aspect of the elevator hydraulic station, so it should not be taken lightly. Moreover, from a professional perspective, there are relevant rules and requirements. You should refer to the specification manual, so that you can have a correct understanding and know how to achieve better cleanliness.
.Outriggers: mechanical outriggers, hydraulic outriggers ordinary hand cranking outriggers, and pull-out outriggers.
In addition it is strictly prohibited to use a hammer during installation to prevent excessive axial or radial force from damaging the bearings or gears. Be sure to tighten the mounting bolts before tightening the tension bolts. Before installation, clean the anti rust oil on the motor input shaft, positioning boss, and elevator connection parts with gasoline or zinc sodium water. Its purpose is to ensure the tightness of the connection and the flexibility of operation, and to prevent unnecessary wear and tear.
The hydraulic lifting platform mainly uses hydraulic oil pressure transmission to achieve the lifting function. Its shear fork mechanical structure provides stability for the lift. The wide working platform and high bearing capacity make the high-altitude operation range wide and suitable for multiple people to work simultaneously. It makes aerial work efficient and guaranteed.

How to solve the problem of oil pipe leakage due to the sinking of the elevator? It may be caused by damaged seals or cracks in the oil pipe, resulting in a pressure drop and inability to support the oil pipe to a large height.
Scissor type fixed lifting platform is a transportation and loading equipment that transports goods from one height to another. After operation, the platform is level with the ground, without occupying ground space and affecting passage passage.
reform.The water cooling of hydraulic stations is generally tubular water cooling, and the type selection is based on the heat load to calculate the heat exchange area, while the air-cooled elevator is conducted using an air cooler, and the heat exchange capacity is calculated based on the heat load. Then, the type selection calculation is performed when the flow can be satisfied. Therefore, the two types of cooling are different, and there are significant differences. Long-term lifting and lowering of cargo elevator factory
Secondly, there should be no dirt on the friction surface. If there is any dirt, it should be washed off with gasoline or thinner; The reduction gearbox, gearbox, external meshing gear, and other parts of the equipment, as well as the hydraulic oil, must be tested according to the requirements in the table; Correct maintenance of the hydraulic guide rail elevator: Regularly inspect the wire ropes at various parts for broken wires and looseness. If any such phenomenon is found, replace it in a timely manner. The maintenance of the wire ropes must be carried out in strict accordance with the specifications; Check the connection condition of each part according to the braking rules and regulations. If there is any looseness, tighten it in a timely manner. Check the tightness of the connecting bolts of the equipment when the body is under pressure. All connecting shafts should be equipped with cotter pins; Check whether the operation of each mechanism is normal, whether there are noises and faults according to regulations, and promptly remove all faults; When installing, disassembling, and adjusting the rotating mechanism of the equipment, it is important to note that the reducer and the gear center line should be parallel, and the meshing clearance should be appropriate; Regularly conduct a comprehensive inspection of the equipment to see if there is any damage to the wires and cables, and if there is overheating of the motor. Replace the motor in a timely manner and eliminate the fault before continuing operation; Ensure that the bearings, boxes, distribution boxes, and brushes of the motor are kept clean, and that the travel switch points of each safety device must be safe and reliable.

Variable cost.Characteristics of hydraulic elevators: Hydraulic lifting platform products are divided into curved arm type hydraulic lifting machines, scissors type hydraulic lifting machines, mast type hydraulic lifts, and straight arm type hydraulic lifts according to their working modes. Hydraulic elevator is a replacement product of folding arm elevator (lifting platform) and scissor fork elevator (lifting platform). It can be widely used for the decoration and decoration of stations, docks, airports, hotels posts and telecommunications,malpensa airport Outdoor simple lifting cargo elevator, municipal gardens, garages, cleaning companies, or the installation and maintenance of power systems, etc. This elevator has the advantages of light weight, self-propelled walking, electric starting, simple operation, large working area, and especially the ability to cross obstacles for aerial work.
The solenoid valve on the motor should not be adjusted randomly. The solenoid valve is pre adjusted before leaving the factory, and random adjustment can easily cause internal pressure to increase or decrease, which in severe cases can shorten the service life of the motor.
The elevator is a kind of elevator equipment composed of a walking mechanism,malpensa airport Factory lift cargo elevator, an electric mechanism, and a support mechanism. The hydraulic oil forms a certain pressure by a vane pump, and enters the lower end of the hydraulic cylinder through an oil filter, flameproof electromagnetic directional valve, hydraulic control one-way valve, and balance valve. This allows the hydraulic cylinder to move upward and lift heavy objects. The return oil from the upper end of the hydraulic cylinder returns to the tank through the flameproof electromagnetic directional valve, and its rated pressure overflow valve is adjusted. Observe the reading value of the pressure gauge on the pressure gauge.
