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.
Safety performance: The lifting structure is made of high-strength manganese steel rectangular tubes, with a scissors type mechanical mechanism, strong stability, and high bearing capacity. The lifting height is about 10 meters, and the load capacity is about 10 tons.
Chula Vista.'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.
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.
.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.
Precautions for using guide rail type elevators: Overloading and transporting flammable and explosive products are strictly prohibited.
When a cargo elevator fails it should be repaired by professional personnel. It is not allowed to modify the cargo elevator without permission.
Purpose The hydraulic lift is widely used in various industrial enterprises and production lines such as automobile, container, mold manufacturing, wood processing, chemical filling,Chula VistaTwo ton lifting cargo elevator, etc., to meet the lifting requirements of different operation heights, and can be equipped with various table forms (such as ball, roller, turntable, steering, telescoping), and with various ways (separate, linkage, explosion-proof) it has the characteristics of stable and accurate lifting, frequent starting, and large load capacity, Effectively solve various lifting and lowering operation difficulties in industrial enterprises, making production operations free. Professional elevator factory has advanced technology, strict testing, more affordable prices, and more preferential treatment. Welcome to consult
The daily maintenance of guide rail type lifting equipment should pay attention to regular inspection and maintenance, eliminate hidden dangers, and eliminate faults. Doing so is beneficial to improving work efficiency, extending the service life of the equipment, and ensuring the safety performance of the elevator.
Safety performance: The lifting structure is made of high-strength manganese steel rectangular tubes, easy to maintain, strong stability, and high bearing capacity. The lifting height is about 10 meters, and the load capacity is about 10 tons.
Sales Department.'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.'.
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.
Characteristics of hydraulic elevators: Hydraulic lifting platform products are divided into curved arm type hydraulic lifting machines, scissors type hydraulic lifting machines, mast type hydraulic lifts, and straight arm type hydraulic lifts according to their working modes. Hydraulic elevator is a replacement product of folding arm elevator (lifting platform) and scissor fork elevator (lifting platform). It can be widely used for the decoration and decoration of stations, docks, airports, hotels, posts and telecommunications, municipal gardens, garages, cleaning companies, public building facades, or the installation and maintenance of power systems, etc. This elevator has the advantages of light weight, self-propelled walking, electric starting, self supporting legs, simple operation, large working area, and especially the ability to cross obstacles for aerial work.
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.
analysis.The elevator is a kind of elevator equipment composed of a walking 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, 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.
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, 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.
Motor connection error. When the triangular connection motor is mistakenly connected into a star shape,Chula VistaFixed lifting hydraulic cargo elevator, 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,Chula VistaHydraulic guide 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, and in severe cases both the windings and the iron core will overheat, the windings will be burned.
Chula Vista.Different. (Specific bearing capacity and lifting height can be designed and customized according to user requirements)
Carefully prepare a special construction plan for installation and construction, and provide safety technical disclosure to installation personnel.
Regardless of whether it is used outdoors or indoors, it is inevitable that some small problems will occur after a long period of time. At this time, what we should do is to maintain and maintain the elevator. How to follow the steps correctly becomes a difficult problem. Let me explain it to you.
