XingtaiGuide rMotor 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, 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.
Carefully prepare a special construction plan for installation and construction, and provide safety technical disclosure to installation personnel.
Xingtai.How to install and use the bearings of the elevator During the process of installing the bearing device of the elevator, we cannot always ensure that the bearing device has the correct orientation, which inevitably leads to some devices not in place or bearing misalignment. Once these problems occur in the device the clearance between the bearings becomes too small, and then the inner and outer rings of the bearings cannot be located at the same rotation center. Therefore,XingtaiSimple lifting cargo elevator requires, when installing bearings, it is necessary to use specialized tools, and in the future, it is also necessary to use a detector to test the bearing device, so as to ensure the success of the bearing device.
Several 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.
.Hydraulic pump station: domestic lifting platform dedicated pump station Italian imported pump station with external protective devices: organ m type, mesh type, and provide safety technical disclosure to installation personnel.
Different. (Specific bearing capacity and lifting height can be designed and customized according to user requirements)
Hydraulic lifting platforms are widely used in factory maintenance, municipal construction, and decoration of hotels in industrial and mining enterprises, with reliable quality and perfect performance.
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, 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, stable transmission, vibration absorption and noise reduction, light weight, wear resistance, and self reliance, making the design of the elevator more humanized.
Test the goods elevator every day to see if it can operate normally.
Quality improvement.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,XingtaiFixed guide rail type cargo elevator, 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.
Knowledge popularization and superior performance of scissor fork type fixed lifting platform: equipped with safety devices to prevent overloading of the lifting platform; Equipped with a protection valve to prevent hydraulic oil pipe from cracking; Equipped with an emergency lowering device for sudden power failure; The doors of the upper and lower floors are equipped with safety devices that interlock with the system.
Corrosion prevention measures for the body of aerial work vehicles Attention to small scratches The paint surface of aerial work vehicles often corrodes. In addition to common collisions, scratches, and small rocks on the drive tire, there can also be a paint peeling point that can cause a small rust over time. Because most of these scars are small and easy to ignore. Therefore, regularly inspect the engine compartment lid and surrounding areas, go to a professional beauty shop for processing in a timely manner.
Before installing the elevator,XingtaiGuide rail type simple lifting cargo elevator, confirm whether the motor and the elevator are intact, and strictly check whether the dimensions of each part connecting the motor and the elevator match. Here are the dimensions and fit tolerances of the positioning boss, input shaft, and elevator groove of the motor.
Price.Usage: Scissor fork type fixed lifting platforms are mostly used for goods transportation between height differences in production lines, adjusting the working height during workpiece assembly, feeding materials to loading machines at high altitudes, lifting components during assembly of large equipment, matching storage and loading sites with forklift trucks and other transportation vehicles for rapid loading and unloading of goods, vehicle lifting, fixed three-dimensional parking and other places.
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 hydraulic lifting platform can be divided into four wheeled mobile type, two wheeled traction type, vehicle modified type vehicle type, and the lifting height varies from a meter to 1 meter.
Xingtai.Prepare the foundation according to the foundation plan, pay attention to alignment, leveling, and alignment, and ensure the level of the foundation and various usage requirements.
Low cost: Compared to the scissor type mobile lifting platform, the cost is much lower. Therefore, when purchasing a lifting platform, it is necessary to consider the use range, frequency of work, load, and other factors of the lifting platform to select a lifting platform suitable for the work requirements.
To ensure excellent power supply at the installation site, install a separate distribution box. When using the distribution box, the electrical leakage switch must meet the requirements for construction elevators. If the installed construction elevator is variable frequency, the selection of the leakage switch should be compatible with the frequency converter.
