The impact of low temperature on the lifting platform

The impact of low temperature on the lifting platform

The impact of low temperature on hydraulic elevators is specifically manifested in its influence on the hydraulic transmission system, which can be reflected on two levels.

1. Low temperature affects the quality of hydraulic oil.

Hydraulic oil is a key substance in the transmission of driving force in hydraulic transmission systems. The inspection of hydraulic lifting platform components is to check whether there is any deformation, cracking, poor contact, etc. in the structure and welding of the metal components of the lifting machinery (sh è b è i), such as the legs, rotating worktable, support frame, arm, etc., and whether the connection of the shaft pins and the anchor bolts are damaged or loose. The key indicators of hydraulic oil quality (target aim) include viscosity, viscosity coefficient, open flash point, cold filter point, moisture content, etc.

Low temperature can cause water in the hydraulic oil of fixed hydraulic elevators to condense and turn into ice or ice. The condensed ice or ice adheres to the surface of gate valve components and oil filters in the hydraulic transmission system, affecting the total flow rate of hydraulic oil and reducing the speed of fixed hydraulic elevators. Elevators undergo rigorous testing throughout the entire production and manufacturing process. However, if guide rail elevators are not introduced into the sales market, it not only poses safety risks but also affects work efficiency. Strict management is inevitable. Below, we will explain the technical standards for elevators. The inspection of hydraulic lifting platform components is to check whether there is any deformation, cracking, poor contact, etc. in the structure and welding joints of the supporting feet, rotating worktable, support frame, arm, etc. of a part of the metal components of the lifting machinery, and whether the connection of the shaft pins and the anchor bolts are damaged or loose. When it is severe, it can block the gate valve, causing the characteristics of the sealing ring. Low temperature causes the sealing ring to collapse and harden, affecting the actual sealing effect, causing oil seal leakage, and affecting the normal operation of the fixed hydraulic lift. Elevators undergo rigorous testing throughout the entire production and manufacturing process. However, if guide rail elevators are not released into the sales market, it not only poses safety risks but also affects work efficiency. Strict management is inevitable. Below, we will explain the technical standards for elevators. Installing a leakage protection switch on the lifting platform: This behavior is quite common in household electricity consumption. Applying this method to production and manufacturing is a convenient and reasonable way to avoid electric shock accidents.
