4. Requirements for Box Room Components (Mechanical)

⑴ Deuterium gas box chamber

The opening and closing direction of the box door is facing the box door, and the hinge component is opened to the right. Large load-bearing capacity, it is recommended to use no less than one set of guide rail slider components;

The chamber is made of steel structure, consisting of the chamber body and an outer frame reinforced with SUS304 material. Whole welding production.

Thickness of the container body: ≥ 10mm        

Strengthen the thickness of the frame: ≥ 18mm

Strengthen the frame height: ≥ 80mm

The surface inside the box is smooth and clean, without obvious burrs or sharp angles, and the box does not corrode or produce related pollutants;

There are dedicated grooves on the outer surface of the box for laying hydraulic pipelines in the box room;

The outer surface of the box shall be decorated with smooth stainless steel wrapping with a thickness of not less than 1.5mm;

The top of the container room is equipped with lifting lugs for hoisting;

The front end face of the box chamber is flat and equipped with a sealing strip (which can be installed on the box door or the box chamber). It is required to be able to seal tightly after clamping with the box door, maintain pressure after pressurization and vacuuming, and the pressure difference change should not exceed 1%;

Install rotating hydraulic cylinders on all four sides of the front end face of the chamber; Two handwheels are installed on the left and right sides respectively;

⑵ Box room door

The box door opens to the right. Facing the compartment, the hinge component is installed on the right side of the compartment; The left side and top surface are equipped with phase pipeline connection ports;

The door of the compartment is made of steel structure, consisting of a body and reinforcing ribs, with a material thickness of SUS304. Whole welding production. The cabinet door is installed on the cabinet through hinge components. Due to frequent daily use, it is required that the box door be easy to open and close, and the phenomenon of door sinking is strictly prohibited;

Thickness of the container body: ≥ 20mm        

Strengthen the thickness of the frame: ≥ 18mm

Strengthen the frame height: ≥ 80mm

The inner surface of the box door is smooth and clean, without obvious burrs or sharp angles, and there is no self corrosion or generation of related pollutants;

The outer surface of the box door shall be decorated with smooth stainless steel wrapping with a thickness of not less than 1.5mm;

Visual window, located vertically in the middle of the box door, equipped with one circular visual window with a diameter of 110mm;

The inner end face of the box door is flat and equipped with a sealing strip. (Either the compartment or the door should be equipped); The sealing strip is provided by our company;

On the left side of the box door, there is a stainless steel handle that is securely installed;

The reinforcing rib of the box door is placed on one side of the box, that is, the reinforcing rib and the sealing ring are on the same side.

⑶ hinge components

Due to the direct connection between the compartment and the door through hinge components. The box door is wider and heavier, so the hinge component needs to use a guide rail slider component; The slider component uses the ultra heavy load category for the guide rail, and the slider uses the ultra heavy load roller category; The bearing uses heavy-duty tapered rollers, genuine SKF; The load-bearing shaft is made of 38CrMoAlA nitride steel and requires quenching, tempering, and nitriding treatment;

The connection between the hinge component, guide rail fixing plate, and the box chamber should be bolted first, adjusted for positioning, and then welded together; The connection between the connecting plate and the box door should be bolted first, and then welded and reinforced;

⑷ Locking device

The sealing between the box door and the box chamber is now manually assisted by clamping, and then clamped by rotating the hydraulic cylinder to achieve the final sealing and long-term pressure holding requirements;

Auxiliary clamping of the box chamber, with a stainless steel handwheel with a diameter of not less than 180mm on each side of the box chamber door for locking;

Each compartment has a total of 17 rotating hydraulic cylinders, distributed and installed on the four sides of the front end face of the compartment. The opening and closing of the chamber require the hydraulic cylinder to work simultaneously. Due to the small stroke and large quantity of hydraulic cylinders, in order to ensure safe operation, it is required that the clamping and loosening of hydraulic cylinders can be manually adjusted for speed, that is, the main pipeline needs to be equipped with a speed control valve.

Rotating hydraulic cylinder, using HSC-63 model;

The hydraulic cylinders from the hydraulic station to the box room need to be numbered and arranged according to the specifications outside the box room due to the large number of hydraulic pipelines; (It is recommended to strengthen the groove of the box room for pipeline laying) Hydraulic pipes should be equipped with High-quality high-pressure resistant oil pipes, and it is recommended to use stainless steel hard pipes; Easy to arrange on the exterior surface of the box;

For the convenience of operation and the standardization and cleanliness of the site, the four buttons for clamping, releasing, emergency stop, and displaying the working status of each hydraulic cylinder in the hydraulic station need to be centralized on our corresponding machine operation panel.

⑸ Component requirements:
