Impact of hydraulic jack ventilation on optimal lift and hydraulic elevator performance
Hydraulic lifts have different parts, each of which has a specific task. The oil jack is one of these parts that must be ventilated for better performance over time. Venting the oil jack is not a difficult task; But it requires high experience. Also, if you do not know the types of jacks and the function of these parts, it is not possible to move the cabin.
The importance of recognizing the performance of the oily jack in its ventilation
Knowing the function of the oil jack and its role in the executive system of hydraulic lifts and elevators is a big step to start venting the oil jack inside these devices. These jacks are very easy to operate; But at the same time, they perform complex responsibilities that help to increase the working efficiency of elevators. The presence of air inside the oil jacks of hydraulic lifters increases the speed of the oil oxidation process and the lack of proper control of the jack movement and the spongy performance of this part. For this reason, to exhaust the existing air, there is an emergency exhaust port and a guide bush on the end cap, which are closed by a screw. In general, the main algorithm used in oil jacks of hydraulic lifts is the necessity of the oil not being dense so that it can apply the appropriate force to the oil in it.
Accordingly, the process of moving the cabin by jack includes
◾️ Creating oil flow by hydraulic pump
◾️ Movement of the moving part of the jack by oil flow
◾️ opening of the main channel of oil movement to the hydraulic jack by the control valve
◾️ Oil passing through the pipes and hoses of the cylinder duct and its entry into the jack
◾️ Pushing up the jack shaft by the oil entered with a continuous flow
In other words, if the ventilation of the oil jack installed in the elevators and hydraulic lifts is not done properly, the cabin will move abnormally and upward movements will be observed when the cabin is empty. For this reason, in order to increase the safety of the people inside the cabin and the proper operation of the pistons, airing the oil jack is an important principle in the repair and service of hydraulic elevators and elevators.
The effect of the type of moving the hydraulic lift jack on the basic ventilation
Hydraulic jacks are examples of high-capacity hydraulic cylinders that only work in one direction. In the structure of these parts, instead of a piston, a rod with a large diameter is used, which has a shoulder at the end so that the rod does not separate from the cylinder shell. In fact, the oil jacks of the elevators have only one oil passage, and the oil enters and leaves from only one source.
