PwaviTen ton lMotor 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.
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.
Pwavi.'The sinking of a cargo elevator is a phenomenon where the table surface drops due to gravity after a certain period of time after rising to a specified position. Of course, this problem must be abnormal, so how can we solve it?'? The first step is to find the reason, and the following editor summarizes the ultimate solution.
Scissor type fixed lifting platform is a transportation and loading equipment that transports goods from one height to another. After operation, the cost is much lower. Therefore without occupying ground space and affecting passage passage.
.Low cost: Compared to the scissor type mobile lifting platform, 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.
Carefully prepare a special construction plan for installation and construction, and provide safety technical disclosure to installation personnel.
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,PwaviProfessional guide rail type cargo elevator, and to prevent unnecessary wear and tear.
After the goods are transported, clean the platform.
Chemical derusting is a type of derusting that uses acid to chemically react with the metal parts of the screw elevator to remove the rust products on the rust surface of the push rod. This type of derusting is mainly used for large mechanical screw elevators, and attention should be paid to protecting precision components such as electronic instruments during use to avoid acid corrosion.
Precautions for elevator installation: Keep the access road of external construction elevators smooth and have sufficient space for parking equipment. When using a steam crane for auxiliary installation, full consideration should be given to whether the on-site environment meets the operating conditions of the steam crane.
Quality documents.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 cleanliness of the hydraulic station is an important aspect of the elevator hydraulic station, so it should not be taken lightly. Moreover from a professional perspective, so that you can have a correct understanding and know how to achieve better cleanliness.
The water cooling of hydraulic stations is generally tubular water cooling, 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
It is strictly prohibited for personnel to climb up and down the floors by using the goods elevator privately.
Workshop cost.The brake operators of each mechanism on the equipment should regularly check and adjust the clearance of the brake shoe and brake wheel, ensuring flexibility and reliability. Long term improvement of the elevator factory,PwaviTwo story cargo elevator, a 20 year old brand with competitive prices and guaranteed quality!
After careful inspection, it was found that there were two main causes: loss of hydraulic pressure, and leakage of hydraulic valves or seals.
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, diesel engine.
Pwavi.Precautions for elevator installation: Keep the access road of external construction elevators smooth and have sufficient space for parking equipment. When using a steam crane for auxiliary installation, full consideration should be given to whether the on-site environment meets the operating conditions of the steam crane.
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,PwaviFixed hydraulic lifting cargo elevator, no one should stand around to watch.
It should be noted that compared to some lifting platforms in certain venues, protective barriers are generally added to the platform. As lifting platforms belong to special equipment, the National Quality Inspection Bureau strictly inspects this area. Any lifting platforms that are deemed to have safety hazards must be removed. Therefore, when personnel ask if you need to add guardrails, do not blindly refuse, and consider whether it is necessary based on the site of use. 'In addition, it is necessary to possess two types of certificates, namely, the Special Equipment Manufacturing License of the People's Republic of China and the Special Equipment Installation, and Maintenance License of the People's Republic of China, before production, installation, and maintenance can be conducted. Therefore, it is necessary to ask the manufacturer whether they possess these two types of certificates.'.
