In our daily life, the elevator is one of the things we often use. Especially in some office buildings, the use rate of elevators is much higher. Many people are very interested in the principle of elevator's manned use, but they don't know much about it. So tonight, we will introduce the principle of elevator buffer performance in detail. Related introduction.
1、Basic Principle of Elevator Buffer
In the design of CPU, the DC load capacity of output line can drive a TTL load. In the connection, an address line or data line of CPU may connect multiple memory chips, but the memory chips are mostly capacitive loads, and the DC load is much smaller than the TTL load. Therefore, in small-scale systems, CPU can be directly connected with memory, and buffer is needed in large-scale systems. If any program or data is to be used by CPU, it must be put into main memory (memory), that is, CPU only exchanges data with main memory, so the speed of main memory determines the running speed of the system to a great extent.
2、Introduction of Throttle Principle
Under the same stopping conditions, the buffer has a short time. Most of the kinetic energy is stored in oil through accumulator, and the other part is consumed by heat through throttling. In theory. The best way of throttling is trapezoidal convex and porous. In this paper, we must consider the structure, function, cost and other factors to determine the optimal buffer performance scheme from the theoretical design, and use radial distribution throttle orifices to achieve the throttling of the buffer process. Although the piston accumulator is not as sensitive as the leather bag accumulator, and has high requirements for cylinder block processing and piston seal performance, the design can achieve the integration of buffer structure, reduce the cost and compact structure. Therefore, the piston accumulator is finally selected.
3、Elevator Hydraulic Buffer Distance
In order to prevent the traction drive elevator from overspeeding in the upward running process of the car and causing the elevator to rush to the top, the upper end station forced deceleration switch, upper limit protection switch, upper limit protection switch, up-going overspeed protection device and counterweight buffer are installed on the elevator as safety protection devices. The upper limit protection switch and the upper limit protection switch are used to protect the elevator safety by braking. When the brake of elevator car fails at the level of the highest station and the weight of counterweight is greater than the weight of the car, the lift will slide up to the top of the car. When the car is at the level of the highest station, for the energy storage buffer, the distance between the top of the buffer and the collision plate of the counterweight device should be 200 MM-350 mm, and for the consumption. Energy buffer, the distance should be 150 mm - 400 mm.
The above is about the elevator buffer performance and principle. The whole content introduces that the elevator is actually a very complex product. Its internal structure and internal structure are also quite complex. For ordinary people, as long as we understand the basic principles, if the elevator appears phase. If the accident happens, we can make some simple judgments in time.
