Hydraulic wrench working principle and application overview
A hydraulic torque wrench (hydraulic wrench) is a professional bolt tightening tool which is powered by hydraulic pressure and provides high torque output. It is used to install and disassemble bolts. It is often used to tighten and loosen bolts larger than one inch. The maximum output torque of the hydraulic torque wrench can reach 110000Nm, which not only improves the working efficiency, reduces the labor intensity, but also greatly improves the installation quality, and is also conducive to on-site safety management.
The use of hydraulic wrenches is very extensive. In the construction, maintenance and repair work of shipbuilding, petrochemical, construction, electric power, mining, and metallurgical industries, hydraulic wrenches are a very important tool for the installation and disassembly of large-size bolts. There is no substitute for other tools. Not only is it easy to use and light, but the torque provided is huge and accurate. Torque repeatability is around 3%. According to relevant statistics, about 50% of equipment operation failures are caused by bolt problems, and the number of major equipment accidents caused by bolting problems is also very alarming. Therefore, in the process of equipment installation, overhaul and repair, bolts are tightened. Solid and dismantling torques are required to be more stringent in most cases, and manual methods are difficult to achieve. Hydraulic bolts are the ideal choice for bolts with large torques.
The hydraulic torque wrench is composed of a working head, a hydraulic pump and a high-pressure oil pipe. Through the high-pressure tubing, the hydraulic pump transmits power to the work head, which drives the tightening or loosening of the rotating nut of the work head. Hydraulic pumps can be powered by electricity or compressed air.
The working head of a hydraulic wrench consists of three parts: a frame (also called a housing), a cylinder, and a transmission component. The output force of the cylinder, the cylinder piston rod and the transmission part constitute a pair of motion. The distance from the center of the cylinder to the center of the transmission part is the arm of the hydraulic wrench. The output of the cylinder is multiplied by the arm, which is the theoretical output torque of the hydraulic wrench. Due to the frictional resistance, the hydraulic wrench The actual output torque is less than the theoretical output torque.
Hydraulic wrenches are driven hydraulic torque wrenches and hollow hydraulic wrenches two series. Drive-type hydraulic torque wrenches are used with standard sleeves. They are universal hydraulic wrenches and have a wide range of applications. The hollow hydraulic wrench has a thin thickness, which is particularly suitable for a relatively narrow space. Applicable to electricity (nuclear power, wind power, hydropower, thermal power), ships, metallurgy, transportation, cement, construction, aviation and other fields.
Since the hydraulic wrench is often used in a narrow space and a very inconvenient transportation during the construction process, the size and weight of the wrench are the most important indicators. In order to reduce the size of components, the use of high-strength alloy materials and heat treatment are common methods.
For the use of high-strength alloy materials and heat treatment methods to achieve the purpose of reducing the size and weight of the parts. Due to the current widespread global trade, the difficulty of finding high-strength materials is not very difficult. However, in order to increase the strength of one part, heat treatment and surface treatment must also be adopted. It is desirable that the strength of the parts is more than 1000 MPa and stable, and for the material The uniformity of the strength is also extremely high (mainly due to the irregularities of the internal parts of the hydraulic drive wrench). At present, domestic enterprises are still difficult to achieve the strength of the internal parts of the hydraulic drive wrench above 1000 MPa, even if they can be achieved individually. It is difficult to achieve batch stability. It is also necessary to learn more from similar products abroad, invest more manpower and funds in a longer period of time, and try and experiment with materials and heat treatment.
The Super Bright LED Grow Light features LED technology that has an optimised light spectrum for plants. Ideal LED Grow light suitable for all stages of plant growth,especially the vegetative and flowering stage. LED Grow Light can be used as a primary lighting or as a supplemental lighting source or supplemental lighting in dark areas in an indoor grow room environment. LED Grow strip light comes in 24VDC and produces very little added heat, reducing the cost of cooling. This saves energy over standard HPS lighting solutions and reduces cost of operations in indoor grow operations.
With conventional indoor lighting such as Metal Halide, compact fluorescent and LED, the rigid light fixture is on the top of the plant projecting the lighting down onto the plant with great light loss and light efficiency at the side and bottom of the plant. However with the LED Grow Strip light can shape around a plant to deliver lighting in all areas with the optional Bendable Aluminium Channel and Liner adjustable Channel system. The strip can be cut at marked intervals and shaped to create different grow structures for side lighting plant material. This delivers maximum power and precise lighting to areas that are difficult to reach with traditional light fixture.
Advantages

Appliation:Greenhouse, Hydroponics,Aeroponics,Home Garden,Farm,Vegetable Shed,Botanic Garden,Flower Exhibitions,Horticulture,Hydroponics, Hemp Cultivations,Medical Plants Cultivations,etc.
Warnings:
1.lndoor use only.
2.To avoid being damaged,do not use water or drip irrigation while using.
3.Sunshine lighting time should be 12-18 hours.
4.While irradiating the plants,the height of led grow lamp is not less than 10 inches,low height will cause the destruction of plants.
5.Highly hang the lamp will weaken the energy and affect the growth cycle of the plants, so the lamp should not be hung too high.
6.While taking care of the plants, please spray the leaves and branches 2-3 times everyday,to ensure the the plants do not wrinkle a wither, and have no phenomenon of few fruit, and hard pericarp.

Tell you the truth at the end
Some famous Led sellers announced that they are USA OEM, which is clearly a lie. 90% of led grow lights are made in China, even though you don't want to believe, but it is true. They stock larger amount of led lights from Chinese factory, then sell them online by sticking with their own logo. So don't be fooled by the so-called US OEM.
Truth 2
Some famous led sellers exaggerated the function of Led grow lights. We just want to inform you that if you did not change the traditional growing method, you would not get the high yield. Because the led grow light can not play the full role during the traditional growing method. So communicating with growers who have experienced this then you can try it yourself. Please remember that the growing method is the key point for the high yield.
Truth 3
Do not buy cheap led grow lights any more or some which looks like our lights. The lamp will be put on the market to be designed and tested, and this period is at least six-months or more, what are the details what you won't see. Furthermore, the materials we use are not cheap, such as "Cree" chip and Led Lens. Those two parts can be able to ensure the high output. So do not believe that such $xx.99 can buy led grow lights. It's unbelievable.
