Physiological Injury of Aquatic Plants

1. Insufficient Light

During the growth, due to insufficient light, the photosynthetic intensity of aquatic plants will be reduced, the normal growth and development will also be affected.

For example, red water plants such as Ammania gracilis and Rotala macranda, due to insufficient light, the anthocyanins in the leaves will decrease; while chlorophyll will increase, and then gradually become green. In the case of insufficient light, it also shows yellowing, plant slim and fragile, and abnormal growth.

If it is placed under sufficient light, the water plants will slowly return to normal, and the leaf color will turn green, the red water plants will become bright red and dazzling. Therefore, it is necessary to strengthen the light to avoid light lack that affects the normal growth of plants.We provide fish tank led light online shopping  ,RFQ today.

2. Water Temperature (Too High or Too Low)

When the water temperature of the fish tank is too high, the leaves or young parts of the aquatic plants will be damaged, and the phenomenon of fallen leaves or yellowing will occur. Finally, the leaves will easily rot and dissolve.

When the temperature is too low, it will affect the growth and development of most tropical or subtropical aquatic plants. For example, the metabolic function of the plant reduced, and the growth is stagnated. Sometimes necrosis, rotten roots and other symptoms will also occur in the whole plant or part of it.

Here we suggest that better use a thermometer to keep daily accurate data.

3. Phyto Dehydration

Dehydration of aquatic plants is a physiological phenomenon (burning branches), which is mainly caused by excessive fertilization.

Since the total ion concentration in the water is higher than that in the aquatic plants, osmosis occurs, leading to the phenomenon of shrinkage. When it is slight, the leaf shape becomes small, and the young leaves do not curl or stretch; if severe, the whole plant leaves will fall off, and gradually rot, finally die.

Bio-mechanical Injury of Aquatic Plants

1. Snail Animals Injury

Mollusks such as snails are the helper to remove algae from the water tank, but sometimes they also endanger aquatic plants to supplement food sources.

Injured aquatic plants, leaves, and stems are incomplete, which will often affect the ornamental effect. In addition, the injured area is also susceptible to bacterial infection. The only solution is to remove the snails quickly.

2. Fish Damage

Some species of tropical fish use waterweed as a source of food in their place of origin. Nowadays it is raised as an ornamental fish, although it is fed with artificial feed, it still cannot change the habit of eating water grass.

Therefore, avoid raising herbivorous fishes such as tinfoil barb and Eyespot pufferfish in the water tank. Some fish, such as the Clown Loach, do not eat water plants, but they have the habit of digging holes, so they also hurt the roots of aquatic plants.

Background technology of Quadcopter Vibration Isolator manufacture:

Quadcopter includes some special equipment which need stable environment in work engineering, such as inertial measurement device. Influenced by the external air resistance and its own power plant, the four-axis vehicle will generate vibration excitation during flight and transmit it to the specific equipment, which will produce greater vibration on the specific equipment.

The inertial measurement device is one of the core sensors of the four-axis vehicle. It is used to measure the angular velocity and acceleration of the Quadcopter body, and then to calculate the attitude of the Quadcopter. This ensures the safe navigation of the Quadcopter in the external environment. For inertial measurement devices, measurement accuracy is one of the most critical indicators. The noise caused by the vibration of the fuselage is an important factor affecting the measurement accuracy of the inertial measurement device.

The traditional quadcopter vibration isolation of the fixed inertial measurement device by suspending the shock absorber ball and installing the fixed inertial measurement device. However, the natural frequencies of the translational vibration modes of the shock absorber mounted on the suspension ball in three directions are quite different. The so-called three directions are one vertical direction and two horizontal directions. The natural frequencies corresponding to the translational modes in the vertical direction of the vibration absorber are much larger than those corresponding to the translational modes in the two horizontal directions. This makes it impossible to isolate the vibration in three directions simultaneously when the vibration is passed through the vibration absorber, so that the measurement accuracy of the inertial measurement device is poor.

Technological implementation elements:

Based on this, it is necessary to provide a Quadcopter and its vibration absorber to solve the problem that the three-direction vibration can not be effectively isolated at the same time when passing through the vibration absorber and the measurement accuracy of the inertial measurement device is poor.

A vibration absorber is used to connect the fuselage of a Quadcopter and an inertial measurement device. The vibration absorber includes:

The bellows body is used to absorb vibration and deform. The first extension part is arranged at the end of the bellows body, and the first extension part is used to connect the fuselage. The second extension part is arranged on the bellows body far from the end of the first extension part. The second extension is used to connect the inertial measurement device.

The quadcopter vibration isolation and the quadcopter is arranged at the end of the bellows body, and the first extension connects the fuselage. The second extension part is arranged on the bellows body far from the end part of the first extension part. The second extension is connected with the inertial measurement device, so that the fuselage and the inertial measurement device are connected together through the vibration isolation device of thequadcopter. Because the bellows are used to absorb vibration and deform. When the quadcopter vibration isolation is transmitted to the vibration isolation device of the four-axis vehicle, the bellows absorb the vibration and contract or elongate or bend, so that the vibration is transmitted to the inertial measurement device through thequadcopter vibration isolationat a lower frequency. The quadcopter vibration isolation mentioned above greatly increases the horizontal dimension of the quadcopter vibration isolation. This makes the horizontal dimension of the vibration isolation device larger than the vertical dimension, and makes the natural frequencies of the translational vibration modes corresponding to the three directions of the quadcopter vibration isolation basically consistent. It solves the problem that the natural frequencies of the three directional translational modes of quadcopter vibration isolation differ greatly. Because the vibration in three directions can be effectively isolated when passing through the vibration isolation device of four-axis aircraft, the measurement accuracy of the inertial measurement device can be guaranteed, and the problem of poor measurement accuracy of the inertial measurement device can be solved. In the design, the natural frequencies corresponding to the translational modes in the three directions of the fuselage can be adjusted by changing the dimensions, shapes and wall thickness of the bellows.

Hoan is one of the leading quadcopter vibration isolation manufacturers in China, Welcome for enquiry.

At present, the use of industrial vibration damper is very common in industrial production. There are already a lot of industrial manufacturers that use industrial vibration dampers for production. The industrial vibration dampers can play a great role, when used, they can well reduce the vibration sense of the equipment and the noise in the environment. Of course, when choosing, we need to have a careful understanding of the product, and we need to make a comprehensive selection.

Industrial vibration dampers are selected according to the environment and the use of equipment. Industrial vibration dampers should be selected first to understand the environment in which they are used. At the same time, the selection of industrial vibration dampers should require that the quality, installation and after-sale service are guaranteed, so it is important for merchants to find them. Faraday, a special agent providing vibration damper products in Fuzhou, which is very complete in vibration damper products, such as industrial rubber vibration damper, industrial shock absorber, etc., which can be provided in industrial production, and they can also provide good guarantee in after-sales service.

Industrial vibration dampers are screened layer by layer when they are used, because the use in industry is very important for safety, environment and production, so careful selection is needed when using them. So what is the biggest role of industrial vibration dampers in industrial production? In the industrial production, it can reduce the noise and alleviate the sense of vibration in the environment. If it can be used with other shock absorbing equipment, it can also well control the source, which is very important for industrial production. Of course, industrial vibration dampers are designed for use in industrial parks. If the seismic source can be found in the process of use, the vibration damper can be used to block the seismic source, which can play a very good role. Generally, the damping of industrial vibration damper is very good, which can effectively reduce noise, reduce vibration and improve environmental purity. Industrial vibration damper plays an important role in industrial production and is an indispensable auxiliary equipment in industrial production.
