What are the precautions for the use of marine doors?
The weight of the marine door and the width of the door are the main factors in choosing the door closer model, and the common doors are fire doors, wooden doors, aluminum alloy doors, glass doors, steel doors, etc. Usually the weight of the door is small, so choose a model with less power, and vice versa. The frequency of door opening is a factor closely related to product quality, and for frequent use occasions, the sealing performance of the product should be required to be good and long-lasting. The factors that should be considered when choosing a door closer are: the weight of the door, the width of the door, the frequency of opening the door, and the requirements and environment of use.
When the door is opened, the door body drives the connecting rod to act, and the transmission gear rotates, and the rack and pinion piston is driven to move to the right. During the right movement of the plunger, the spring is compressed, as is the hydraulic oil in the right chamber. The check valve ball on the left side of the plunger is opened under the action of oil pressure, and the hydraulic oil in the right chamber flows to the left chamber through the check valve.
The factors that should be considered when choosing a door closer are: the weight of the door, the width of the door, the frequency of opening the door, and the requirements and environment of use. When the door opening process is completed, due to the compression of the spring during the opening process, the elastic potential energy accumulated by the marine door is released, and the plunger is pushed to the left side, driving the transmission gear and the door closer connecting rod to rotate to close the door.
