Customized Elevator Oil Buffer Spring Hydraulic Counterweight Energy Dissipation Type for Elevator Safety Device

The selection of elevator oil pressure buffers requires comprehensive consideration of multiple factors. The following are the specific details:

The selection of the buffer is closely related to the rated speed of the elevator. Generally speaking, the higher the rated speed of the elevator, the more energy the buffer needs to absorb. For example, for an elevator with a rated speed of 1.0 m/s, a small - sized oil pressure buffer that can meet the corresponding energy absorption requirements can be selected. For high - speed elevators with a rated speed of 2.5 m/s or even higher, large - capacity and high - performance oil pressure buffers are required to ensure effective absorption of the kinetic energy of the elevator in an out - of - control state.

Elevators with a large load capacity have a greater overall mass. In the event of a fall or other situations, the energy generated is greater. Therefore, compared with an elevator with a rated load capacity of 1000 kg, an elevator with a rated load capacity of 2000 kg needs to select an oil pressure buffer that can withstand greater impact forces and absorb more energy.

The self - mass of the elevator car is also an important basis for buffer selection. The mass of cars varies with different models and specifications. For example, a car made of stainless steel with luxurious decoration will have a greater mass than a car made of ordinary carbon steel with simple decoration. When selecting a buffer, the specifications and models of the buffer need to be determined according to the actual mass of the car to ensure that the buffer can adapt to the actual situation of the car.

The size and structure of the elevator hoistway determine the installation space for the buffer. If the space at the bottom of the elevator hoistway is relatively narrow, an oil pressure buffer with a smaller external size and a compact structure needs to be selected to ensure smooth installation. Conversely, if the installation space is relatively 充裕,some buffers with better performance but relatively larger volumes can be selected.

Well - known brands with reliable quality should be selected. Well - known brands usually have more advanced production processes and stricter quality control systems, and their products have better performance and stability. For example, the oil pressure buffers under well - known international elevator brands such as Schindler and Otis have a good reputation and high recognition in the market.

On the premise of meeting the safety performance requirements of the elevator, price is also a factor to be considered. The prices of oil pressure buffers vary greatly among different brands and specifications. It is necessary to comprehensively compare the performance, quality, and price of the products and select a buffer with high cost - effectiveness to achieve a balance between economic benefits and safety performance
