TautaubanioGooThe 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
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 working current, which increases the copper loss of the winding, causing the winding to overheat or even burn out.
Tautaubanio.As we all know now, elevators and lifting platforms have been widely used in recent years to solve the problems we encounter in daily life. Because working at heights is a high-risk profession that requires the assistance of auxiliary tools to complete certain tasks, the use of elevators is undoubtedly emerging in the domestic machinery market and has been vigorously developed.
The load of this series of products is divided into 0.1 to 0.8 tons, and can also be customized according to user requirements, with a load of up to 10 tons.
.In addition to having a fixed mode, there are also types of mobile elevators. As the name implies, it is a combination of lifting equipment and on-board systems. This type of lifting equipment is very flexible to move, and of course, it is better to use it. For example there are such lifting equipment in airports, and stations or stadiums may also be equipped with such equipment, as it can be moved by itself, The scope of work is not limited to a certain place, but can be used wherever lifting operations are required. For example, when installing outdoor advertisements, some advertisements are relatively high in height. At this time, mobile lifting equipment can be used to send billboards or staff to a designated height for work. This type of equipment can also be divided into two types according to the driving mode: hydraulic lifting and electric lifting. The so-called hydraulic lifting is the use of hydraulic oil to drive to achieve a specified height. The electric mode is driven by a motor or tooth to lift to a certain height. However, currently, hydraulic lifting platforms are more widely used.
Incorrect connection of the elevator motor When a coil, or one phase winding group is connected inversely, it can cause a serious imbalance in the three-phase current and cause the winding to overheat.
Many people believe that the mechanical strength of the elevator itself is relatively high when using the elevator, so the installation method specified in the manual is not strictly followed during the installation process. However, this can lead to increased wear of parts and inflexibility in operation. In addition, it is necessary to pay attention to the installation precautions corresponding to the working environment and not be careless. Correct installation, use, and maintenance of the elevator are important steps to ensure the normal operation of mechanical equipment. Therefore, when installing the elevator, please be sure to carefully assemble and use it in strict accordance with the following installation and use related matters.
Carefully prepare a special construction plan for installation and construction, and provide safety technical disclosure to installation personnel.
The main structure and use of the guide rail type elevator are closed gear transmission, and the large and small gears are made of steel. After quenching and tempering treatment, they belong to the soft tooth surface. As the common failure form of closed soft tooth surface gear transmission is tooth surface pitting, the design is based on the tooth surface fatigue strength and checked based on the tooth root bending fatigue strength. The bracket bracket is used to fix and support all mechanical parts and some electrical components of the elevator chassis. It is mainly welded from parts such as side plates, connecting tubes, and connecting pieces. The materials are all selected, including the thickness of both sides of the plate, products, and tens of millions of products. Professional elevator factory transactions are safe and guaranteed. At the same time, in order to reduce the weight of the bracket, many process holes are designed on both sides of the plate. The worm gear and worm mechanism has the advantages of large transmission ratio, compact structure, small impact load, stable transmission, low noise, and has the characteristics of reverse self-locking. It can ensure that the transmission mechanism can self-lock when the motor is powered off during patient handling, so a worm gear reducer is selected. The involute worm is used, and the material is steel. Its spiral surface is quenched to improve transmission efficiency and increase wear resistance. The worm gear is made of polyformaldehyde. Plastic worm wheels have the advantages of good processing economy, light weight, wear resistance, and self reliance, making the design of the elevator more humanized.
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,TautaubanioGuide rail type cargo elevator, 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.
Customer first.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.
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, namely, the Special Equipment Manufacturing License of the People's Republic of China and the Special Equipment Installation, Transformation 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.'.
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.
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, 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,TautaubanioHigh performance elevator, tighten it in a timely manner. Check the tightness of the connecting bolts of the equipment when the body is under pressure.
