ShanghaiFloor 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, 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.
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.
Shanghai.What is the solution to the problem of rust on the surface of the spiral elevator? Sandpaper has a large loss on the spiral elevator itself. Specializing in products, renewable resources business, including: elevator factory
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.
.Is the water cooling and air cooling of the hydraulic station the same?
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.
The purpose of hydraulic lifting platform Users can choose the power mode and configuration according to their own scope of use: power systems include: DC power supply, single-phase or three-phase power supply,ShanghaiProduction of simple lifting cargo elevators, diesel engine.
The 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
Before using the machine, the staff should carefully check the hydraulic and electrical systems to ensure there is no leakage or bare leakage before using it.
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.
For more, please check.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.
Goods should be stacked well on the platform, no one should stand around to watch.
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.
Carefully prepare a special construction plan for installation and construction and provide safety technical disclosure to installation personnel.
production costs.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,
Small pneumatic or electric derusting, which uses the principle of friction generated by air compression or electromagnetic effects to polish and remove rust on the surface of a spiral elevator, can be used for precision instrument push rods or for enterprises that require micro operation of spiral elevators.
Many people believe that the mechanical strength of the elevator itself is relatively high when using the elevator, 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.
Shanghai.'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.'.
Motor connection error. When the triangular connection motor is mistakenly connected into a star shape, the motor still operates with full load,ShanghaiA cargo elevator needs to, 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.
In addition, it is strictly prohibited to use a hammer during installation to prevent excessive axial or radial force from damaging the bearings or gears. Be sure to tighten the mounting bolts before tightening the tension bolts. Before installation, clean the anti rust oil on the motor input shaft, positioning boss, and elevator connection parts with gasoline or zinc sodium water. Its purpose is to ensure the tightness of the connection and the flexibility of operation, and to prevent unnecessary wear and tear.
