SwarthConstrucIncorrect connection of the elevator motor When a coil, coil group, or one phase winding group is connected inversely,SwarthCustomized lifting cargo elevator, it can cause a serious imbalance in the three-phase current and cause the winding to overheat.
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.
Swarth.Transportation lifting platforms need to be considered. However, in the use of elevators, making it difficult to move back and forth, and it is very difficult to move, So how should we solve it? Today, I will introduce to you in detail how large lifting platforms solve the problem of transportation difficulties.
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.
.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.
'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.'.
Connect the motor to the elevator naturally. During connection, it must be ensured that the concentricity of the elevator output shaft and the motor input shaft is consistent, and that the outer flanges of the two are parallel. Inconsistent centering can cause the motor shaft to break or the elevator gear to wear.
Prepare the foundation according to the foundation plan, pay attention to alignment, leveling, and ensure the level of the foundation and various usage requirements.
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, 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, stable transmission, vibration absorption and noise reduction, light weight, wear resistance, and self reliance, making the design of the elevator more humanized.
Connect the motor to the elevator naturally. During connection, it must be ensured that the concentricity of the elevator output shaft and the motor input shaft is consistent, and that the outer flanges of the two are parallel. Inconsistent centering can cause the motor shaft to break or the elevator gear to wear.
how.What is the new price of fixed elevators? Fixed elevators are currently very popular in the market. Due to different manufacturers, different materials, and different brand awareness,SwarthElevator enterprise, the prices also vary. Currently, the prices of fixed elevators produced in the domestic market are: rated load 1-5 tons, lifting height 7 meters, table size 2500 mm * 2000 mm, and the price is around 27000-45000 yuan; The rated load is 1-3 tons the lifting height is 0 meters, the table size is 2300 mm * 2000 mm and the price is around yuan. Rated load and lifting height of each fixed elevator,
Before installing the 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, and elevator groove of the motor.
Connect the motor to the elevator naturally. During connection, it must be ensured that the concentricity of the elevator output shaft and the motor input shaft is consistent, and that the outer flanges of the two are parallel. Inconsistent centering can cause the motor shaft to break or the elevator gear to wear.
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, 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.
Scheme customization.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.
Avoid, especially during storage. Store in a cool and dry place, and avoid rainy and snowy weather during work.
It is strictly prohibited for personnel to climb up and down the floors by using the goods elevator privately.
Swarth.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,SwarthProduction of lifting cargo elevators, 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.
Precautions for using guide rail type elevators: Overloading and transporting flammable and explosive products are strictly prohibited.
Fixed elevator is a transportation equipment that directly lifts and loads goods from the ground. It is mainly used for goods transportation between height differences in production lines, material loading and unloading, component lifting during assembly of large equipment, fixed three-dimensional parking, and other places. So what is the new price for fixed elevators?
