Motor connection error. When the triangular connection motor is mistakenly connected into a star shape, 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 anti rust work of aerial vehicles is generally something that needs attention when they have not been used for a long time. How should we protect the body of aerial vehicles from corrosion? This is actually a simple matter of not having to spend money on anti-corrosion at the repair station. As long as we car owners use some materials they can find on their own, we can achieve this. At the same time, paying attention to driving habits can ensure that high-altitude work vehicles do not rust. Here are a few points for reference.
dad.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, the design is based on the tooth surface fatigue strength and checked based on the tooth root bending fatigue strength. The bracket bracket is used to fix and support all mechanical parts and some electrical components of the elevator chassis. It is mainly welded from parts such as side plates, 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, 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.
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, a 20 year old brand with competitive prices and guaranteed quality!
.Scissor type fixed lifting platform is a transportation and loading equipment that transports goods from one height to another. After operation, the platform is level with the ground without occupying ground space and affecting passage passage.
Precautions for using guide rail type elevators: Overloading and transporting flammable and explosive products are strictly prohibited.
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, 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 for fixed elevators? Professional improvement of the quality assurance of the elevator factory. Preferential activities are ongoing, welcome new and old customers to consult
If the hydraulic valve is damaged, its effectiveness should be maintained. If it is damaged, it can be replaced in a timely manner.
It is strictly prohibited for personnel to climb up and down the floors by using the goods elevator privately.
Good reputation.It is good for aerial work vehicles not to cover their clothes and park outside. If it is windy and rainy, the clothes will repeatedly slap the car paint, especially if the vehicle blows sand on the clothes, causing many fine scratches on them, as the paint will become black over time. In addition, when the wind does not directly spray powder or clean the mechanism on the sand, it should be washed with water, and prevent the vacuum cleaner of the aerial work vehicle from scratching the sand particles on the paint surface.
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.
Walking: assisted self-propelled, two wheel traction, self driving, and car modification.
Incorrect connection of the elevator motor When a coil, coil group, 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.
How many?.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, input shaft, and elevator groove of the motor.
How to install and use the bearings of the elevator During the process of installing the bearing device of the elevator, 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,dadHydraulic lifting cargo elevator, it is necessary to use specialized tools when installing bearings, 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.
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,dadHydraulic cargo elevator and lifting cargo elevator, no one should stand around to watch.
dad.For guideway elevators installed outdoors, they are often exposed to rain and sunlight, so special attention should be paid to regular maintenance and inspection to avoid accidents.
Carefully prepare a special construction plan for installation and construction, and provide safety technical disclosure to installation personnel.
Large logistics warehousing equipment service company with guaranteed prices and guaranteed services, directly operated by the manufacturer. Because fixed elevators are mechanical equipment, the quality and performance of the product are good. Do not accept products from some manufacturers that do not meet the quality standards, in order to avoid some safety hazards in use.
