Roller Shutter Profile Extrusion Dies
Aluminum alloy rolling shutter
Composition
Because the aluminum alloy of aluminum alloy roller shutters has low density but relatively high strength, which is close to or exceeds that of high-quality steel, aluminum alloy doors have good plasticity and can be processed into various profiles. They have excellent electrical conductivity, thermal conductivity and corrosion resistance, so they are widely used. Used in the door industry, its usage is second only to steel. Aluminum alloy rolling shutters are used in various places such as shops, high-end residential areas, commercial streets, corporate gates, anti-theft windows, bank entrances, etc. Aluminum alloy is the most widely used non-ferrous metal structural material. Anti-theft aluminum alloy rolling shutters can be repaired. Good anti-corrosion performance, after use, can significantly reduce the wear and noise during operation of rolling shutter doors and windows, and increase the service life of components.
Advantage
1. Safety
This product uses reversal technology when encountering obstacles. When it touches people, cars, etc., it will automatically reverse and return; ensuring the safety of the owner's body and property!
2. Strong
The door panel material is made of high-strength color steel imported from abroad. It is formed into one piece by special hydraulic work, and its strength is twice that of ordinary rolling shutters. The concave and convex parts are just tightly connected to each other, and the curvature is reduced by half!
3. Mute
Both sides of the rolling shutter door are made of special aluminum alloy, which has high strength, smooth trajectory, and the entire integrated door shape. There is almost no sound during use. In such an environment, the silencing rope is replaced, making it perfectly silent!
4. Beautiful
The appearance of the door piece is very three-dimensional and prominent, neatly arranged; the protruding part is of appropriate size, the motor is not exposed, and the whole is simple and beautiful!
5. Easy
It uses high-quality anti-fatigue torsion springs internally. Both sides rise and fall at the same time. It has good balance and long life!
6. Practical
Strong and durable, beautiful appearance, high strength, high toughness, corrosion-resistant aluminum alloy double (single) layer curtain, made of aluminum alloy, resistant to hits and scratches, blocking malicious intrusion from outside the door, and more effective security protection.
The appearance of the aluminum alloy rolling shutter door adopts electrostatic powder spraying process, which has strong weather resistance, anti-aging, rain resistance and corrosion resistance, and has a service life of more than 20 years.

(2) oil pump and motor installed in the low board, crane crane, the sling must be suspended in the ring on the floor. Single-lift pump head must be hanging in the import and export of flange pipe, the pump shaft does not withstand external forces.
　　
(3) Pump installation should be selected in a dry and bright place, with the management staff to see the pump in operation. If the pump needs to be close to the wall installation, it must be reserved for easy disassembly and overhaul. Do not install the pump in damp, sun and windy places. If the installation site is flooded, the pump must be above the maximum water level.
　　
(4) The oil pump should be fixed on a solid base, so as to avoid loosening and vibration of the pipe and bolt to prevent deformation of the bottom plate. As a separate pump head mounted on the machine, you must choose the least vibration on the place.
　　
(5) Before installing into and out of the oil pipe, kerosene must be used to flush the inner wall of the pipe. No sundries are allowed. If such substances enter the pump body, the gear will be damaged. Pump inlet and outlet pipe size should not be less than the size of the pump inlet and outlet diameter. Into the pipe should be slightly larger diameter, into the pipe should be as short as possible, the elbow bend radius should be relatively large, the valve on the pipeline gate valve should be used to reduce resistance.
　　
(6) There is no need to install the bottom valve in the oil pump because of the great resistance of the bottom valve. However, it is suggested to install a metal filter at the inlet of the inlet pipe to prevent the sundries from entering the pump body. The effective area of ​​the oil filter should not be smaller than the pipe diameter Double, into the oil pipe outlet should be cut into 45. bevel.
　　
(7) Shaft and motor shaft should be installed concentric, when the installation of concentricity is not good, the rotation may have the clutch caught off.
Gear pump in the installation of what are the requirements?
(1) Before installing the pump, check whether the pump body and the motor are damaged during transportation, such as whether the motor is damp, whether the dust cover of the pump's inlet and outlet is damaged and dirt enters the pump chamber.
