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, 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.
'Using the elevator is not about maintaining and overhauling the equipment after it has failed. It is important to maintain the equipment in accordance with the correct maintenance and overhaul. First, do the preparatory work to eliminate all possible fault problems and accidents. I hope that today's summary of knowledge points by the editor can help everyone.'.
Ruth.Before using the machine, the staff should carefully check the hydraulic and electrical systems to ensure there is no leakage or bare leakage before using it.
The elevator is a kind of elevator equipment composed of a walking mechanism, a hydraulic mechanism, 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, throttle 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.
.Safety performance: The lifting structure is made of high-strength manganese steel rectangular tubes,RuthCar lift cargo elevator, with a scissors type mechanical mechanism, easy to maintain, strong stability, and high bearing capacity. The lifting height is about 10 meters, and the load capacity is about 10 tons.
Frequently check for water accumulation and humidity. It is inevitable for aerial vehicles to drive in rainy and snowy weather, or muddy roads. The bottom and some gaps and indoor floors are prone to sludge accumulation. If the owner does not clean them in a timely manner, this can cause moisture to hide. Therefore, activities in the outer edges of wheel hubs, doors, bottom corners of tree trunks, key holes, and wiper brackets, as well as other areas, should be regularly inspected, and the drainage holes in the doors and various parts should be kept unblocked to ensure that the car seat covers, such as humidity, carpets, and floors, prevent rust from forming parts.
Motor connection error. When the triangular connection motor is mistakenly connected into a star shape, the motor still operates with full load, 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,RuthProduction of lifting cargo elevators, 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, and in severe cases, the windings will be burned.
This fixed lifting device can also be used inside a warehouse, such as lifting a certain layer of the warehouse to transport goods or personnel to a designated warehouse location.
Purpose of manual hydraulic platform: The manual hydraulic transportation platform has novel design, reasonable structure, and convenient use. Suitable for loading, unloading transporting,RuthTen ton lifting cargo elevator, and stacking barrels in factories, warehouses, and oil depots. It is particularly suitable for use in chemical and food workshops as a dumping or batching machine. It can also be used to load and unload heavy objects on trucks, stack them, and cooperate with hydraulic drum trucks. It can greatly improve work efficiency and reduce labor intensity. It can also be modified for loading and unloading and lifting heavy objects. It is a new and ideal multi-purpose lowering and unloading machine.
It is strictly prohibited for personnel to climb up and down the floors by using the goods elevator privately.
Supply chain quality management.It should be noted that compared to some lifting platforms in certain venues, protective barriers are generally added to the platform. As lifting platforms belong to special equipment, the National Quality Inspection Bureau strictly inspects this area. Any lifting platforms that are deemed to have safety hazards must be removed. Therefore, when personnel ask if you need to add guardrails, do not blindly refuse and consider whether it is necessary based on the site of use. 'In addition, it is necessary to possess two types of certificates, namely, the Special Equipment Manufacturing License of the People's Republic of China and the Special Equipment Installation, and Maintenance License of the People's Republic of China, before production, installation, and maintenance can be conducted. Therefore, it is necessary to ask the manufacturer whether they possess these two types of certificates.'.
Nowadays, small and medium-sized enterprises are products with the idea of good quality and preferential prices.
What types of elevators are there? There are many types of such equipment such as fixed lifting devices and vehicular lifting devices, depending on the form of movement. The so-called fixed lifting is generally installed in one place and fixed, and then lifting operations can be carried out. This type of lifting equipment is generally used more on the assembly line, and some large production lines need to lift the materials to a certain position when loading them, and then put them into production on the production line. A special lifting device needs to be fixed at a certain position on the production line.
For guideway elevators installed outdoors, they are often exposed to rain and sunlight, so special attention should be paid to regular maintenance and inspection to avoid accidents.
Recommendation and consultation.Does the cleanliness of the hydraulic station have relevant rules and requirements?
Remove and disassemble the hydraulic elevator lowering valve, then install it and reinstall it.
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, such as lifting a certain layer of the warehouse to transport goods or personnel to a designated warehouse location.
Precautions for using guide rail type elevators: Overloading and transporting flammable and explosive products are strictly prohibited.
