Effect of temperature on the performance of hydraulic lifting jack for synchronous lifting pushing
No matter it is overhauling vehicles or lifting construction bridges and equipment molds, it is inseparable from the application of hydraulic lifting jack for synchronous lifting pushing. No matter what type of hydraulic jack, it is inseparable from manpower control, which affects manpower and hydraulic The working performance of lifting jack for synchronous lifting pushing is influenced by various external factors such as manpower, temperature, and terrain. For example, in the past cold winter season, will the working performance of the hydraulic lifting jack for synchronous lifting pushing application decrease due to the arrival of winter?
The answer is no, because the components of the hydraulic lifting jack for synchronous lifting pushing are all made of cast iron or cast steel, and are less affected by temperature. Take the screw jack as an example, it is a commonly used lifting tool. It has a simple structure and belongs to the mechanical lifting mode. The force acting on the rocker by manpower is gradually transmitted to the small gear and the large gear, and finally becomes In order to be able to lift the lifting sleeve and the force of the weight, because of this, the temperature has a relatively small influence on its working performance.
On the contrary, the power source of hydraulic lifting jack for synchronous lifting pushing is the hydraulic oil inside the cylinder. When the temperature is too high, the viscosity of the oil will decrease and the lubricity will decrease, which will easily lead to oil leakage. When the temperature is too low, the viscosity will increase. The fluidity of the oil is poor, and even the jacking work cannot be completed.
So to a certain extent, this key element can bring us more inspiration and thinking. When the temperature in the working environment is too high or too low, we can choose to use a hydraulic lifting jack for synchronous with relatively stable performance lifting pushing.
