DenverElevatinIncorrect connection of the elevator motor When a coil,DenverBuilding guide rail lifting cargo elevator, 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.
Prepare the foundation according to the foundation plan, pay attention to alignment, leveling, and alignment, the maintenance of cargo elevators should not be careless. The following editor will introduce the daily maintenance of hydraulic cargo elevators.
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.
.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.
'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.'.
Goods should be stacked well on the platform, and should not be tilted. When the goods elevator is lifting or lowering beyond the scope of the platform, no one should stand around to watch.
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.
'Before installing the elevator bearings, we should never open the packaging prematurely. This can easily lead to premature bearing contamination, which can lead to premature bearing damage. In addition, when installing, it is necessary to ensure that the device environment is clean and not to bring iron filings, dust, and other things into the bearings, as even some small dust,', If it continues for a long time, it will also affect the running-in between bearings, leading to a decrease in the life of the elevator.
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?
Inspection items.Outriggers: mechanical outriggers, hydraulic outriggers, 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.
What is the new price of fixed elevators? Fixed elevators are currently very popular in the market. Due to different manufacturers, different materials, different load ratings, and different brand awareness, 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,

Development Curriculum.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.
Main structure and purpose of guide rail type elevator: The mechanical part of guide rail type elevator mainly includes three parts: lifting device, track device, and belt changing device. The lifting device is mainly used to suspend the lifted person, which is the core part of the entire mechanism. The role of track device is mainly to provide movement trajectory, making operation more smooth. The belt changing device is used to switch tracks when the elevator is about to pass through the door. The internal structure of the lifting device is mainly composed of a gear mechanism, a bracket, a worm gear, a guide mechanism, a lifting arm, upper and lower shells, etc. Gear mechanism Gear mechanism mainly includes large and small gears, winding pulley, central shaft, and safety device composed of stop buckle and torsion spring.
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,DenverConstruction site lifting and cargo elevator lifting, 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.

So what is the new price for fixed elevators?
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.
