An automatic tension controller is a high-precision, fully digital, intelligent tension controller, with more advantages and practicality in application and function. It is anti-interference, much more convenient, and stable. It has extremely high tension control accuracy, which is suitable for use in occasions that have high requirements for the accuracy of tension control.
Characteristics of automatic tension controller
1. High accuracy
The signal can be transmitted via the tension sensor, and then the output signal is processed by the intelligent PID. The actuator can be adjusted to control the changes in the diameter of the tensile scale and the appropriate coil. The output accuracy is as high as 0.1% so that the tension control is more accurate and stable.
2.Single/dual input
Receiving single or dual sensor inputting signal with automatic zeroing and calibration.
3.User-friendly interface
Adopts a full touch screen with simple operation and manual and automatic switching.
4.Strong anti-interference
Metal shell with strong anti-interference capacity without sparks.
5.Parameter password protection
Secret code setting will avoid that errors change the setting parameters.
6.Wide applications
Widely used in many industries such as paper-making, printing, packaging, textile, non-woven fabric, etc. The precision of tension control directly affects the processing quality of the product.

The tungsten carbide has high hardness, high strength, good heat resistance, wear resistance, etc. Typically, the nozzle also often uses the tungsten carbide as the raw material. The carbide nozzle is made by the method of cold pressing combined with vacuum sintering, which causes many problems.
The problems existed in the production process
1. It has a high cost of steel molds and the heat treatment is more difficult.
2. The suppressed equipment needs large tonnage with complex mold.
3. High-temperature sintering deformation, which is not easy to control shrinkage and deformation.
4. It is difficult to follow-up mechanical processing, consuming much work time.
5. The waste rate of the sintering in the production process is high
How to improve the performance
Since the coal chemical slurry has ingredients with strong abrasion and high corrosive, To ensure the slurry output with a certain output pressure and long service life, so require carbide nozzle has excellent characteristics such as wear resistance, high preservative, high strength, high hardness.
By using a high-pure graphite mold, a nickel-plated short branch carbon fiber is added, adopting a vacuum hot pressing process, which will greatly improve the comprehensive performance of the wear resistance and anti-corrosion resistance of the carbide nozzle, as well as longer service life.

Life raft has been widely used in various types of navigation ships, playing an increasingly important role in emergency rescue, which is a safe and effective marine life-saving equipment. Compared with other emergency life rafts, inflatable life raft has the significant advantages of small size, lightweight, easy to use, stable performance, safe and reliability.
The liferaft is life-saving equipment without self-propelled capability, used by the crew in the ship. It is equipment that ships getting away from dangerous areas or emergency evacuation. It can be rapidly released into the water and floats over the surface. All kinds of life rafts have a certain buoyancy and can be protected from wind, rain, waves and sunburning with a ceiling, with food and water for survival. It can be stored at a temperature of -10 to + 65 ° C and applied within the temperature range of -1 to +30 ° C.
Two Types Of Life Raft - Rigid And Inflatable Types
Rigid life raft
The rigid life raft, also known as the traditional life-saving raft, its structure is made of galvanized iron, aluminum alloy plate, stainless steel plate. Then the cover is made from the flame retardant material. The top of the raft is provided with a fixed rigid canopy and an entrance, and the bottom is a wooden lattice. The raft is slipped under the water or put down the water with a hanging raft.
The traditional life raft is simple and cost-effective, but the volume is large, cumbersome less carrier.
Inflatable life raft
The inflatable life raft, which is the most widely used liferaft, can be inflated and opened automatically in a short time. It is made of rubber nylon cloth, which can be folded and stored with lightweight. According to its deployment method, there are two types including throw-over type and davit launched type. The most common is a throw-over life raft, and the davit launched liferaft is mainly used for passenger ships.
The davit launched liferaft is to hang life raft at ship side by launching equipment and go inboard from ship’s deck when inflating and to fall it down on the sea by davit. In case of failure in davit launching equipment, the life raft is also designed to be inflated automatically in the same way as throw-over type. It can be thrown out in an emergency, which can also be thrown into the water. The raft can automatically release and float on the water surface.
The self-inflating life raft is designed, when the sea surface is in the overturned condition since the top of the raft is circular, which can reduce contact surface with water, the center of gravity in the bottom of the life raft, after the inflatability is completed, it can be self-centered.
