YuciProfessionThe 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, there are relevant rules and requirements. You should refer to the specification manual, so that you can have a correct understanding and know how to achieve better cleanliness.
Hydraulic pump station: domestic lifting platform dedicated pump station, Italian imported pump station with external protective devices: organ m type, mesh type, and iron plate sealed type.
Yuci.If the hydraulic valve is damaged, its effectiveness should be maintained. If it is damaged, it can be replaced in a timely manner.
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 hydraulic control one-way valve, and its rated pressure overflow valve is adjusted. Observe the reading value of the pressure gauge on the pressure gauge.
.It is good for aerial work vehicles not to cover their clothes and park outside. If it is windy and rainy 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 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.
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.
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.
Before connecting the motor to the elevator, the elevator manufacturer should first make the motor shaft keyway perpendicular to the tightening bolt. To ensure uniform stress, first screw on the mounting bolts at any diagonal position, but do not tighten them. Then screw on the other two mounting bolts at diagonal positions, and then tighten the four mounting bolts one by one. After that, tighten the tightening bolts. All tightening bolts shall be fixed with a torque wrench according to the indicated fixed torque data, and the use of elevators and lifting platforms shall be checked
'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.
Hydraulic pump station: domestic lifting platform dedicated pump station, Italian imported pump station with external protective devices: organ m type, mesh type, and iron plate sealed type.
Welcome calls .Different. (Specific bearing capacity and lifting height can be designed and customized according to user requirements)
Low cost: Compared to the scissor type mobile lifting platform, the cost is much lower. Therefore, 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.
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.
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,YuciIndoor cargo elevator, 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,YuciOutdoor lifting cargo elevator, and in severe cases,YuciFixed lifting cargo elevator, the windings will be burned.
Highly recommended.Systems: explosion-proof electronic control system, PIC system.
Remove and disassemble the hydraulic elevator lowering valve, blow out the plunger with compressed air, then install it and reinstall it.
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, leveling pay attention to alignment, and ensure the level of the foundation and various usage requirements.
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.
'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.'.
