2) It is easy to leak oil, the sealing material has different shrinkage at different temperatures, and it is easy to crack at low temperature;

3) The closing force decays with time, and the strength should be adjusted after a period of time; The torsion spring force decreases with the increase of closing times;

4) At low temperature, the hydraulic oil becomes sticky, and the door is not closed in winter, especially in the north;
