Greenhouse planting is very common in agricultural production and is considered to be a very reliable and stable way to increase crop production. Generally speaking, the temperature of the greenhouse is higher than that of the open air environment, such as the cultivation of vegetables and fruits in the greenhouse, the temperature is generally around 20-25 degrees. This temperature is also a suitable temperature environment for the occurrence of pests and diseases. Therefore, it is easier to produce pests and diseases in greenhouses. In order to achieve green pest control and help greenhouses grow green and high-yield, Top Yunnong has launched insecticidal lamps for greenhouses- Greenhouse insecticidal lamp . There are a lot of pests in vegetable greenhouses. Common varieties include aphids, whiteflies, noctuids, leaf miners, etc. The induced diseases include fusarium wilt, downy mildew, virus disease, powdery mildew, rust, gray mold, etc. And so on, all of these can reduce the yield of vegetables and affect the quality of vegetables. The insecticidal lamp in the greenhouse traps and kills many kinds of pests and the quantity is large, which can greatly reduce the amount of eggs laid by the pests, reduce the base and density of the insect population, and the effect is remarkable. After application, it can effectively reduce the number of insects in the greenhouse and avoid the damage caused by the pests in the greenhouse. At the same time, this green and environmentally friendly green insecticidal method is more in line with the needs of green production in the greenhouse, which greatly improves the cultivation of agricultural products in the greenhouse. the value of. Greenhouse insecticidal lamp is a green prevention and control equipment for insecticide in greenhouses. It uses the characteristics of insect phototaxis to fundamentally solve the problem of single function of traditional night trapping methods in limited space. The innovation of lamps also avoids the problems of pesticide use and residues, guarantees the improvement of quality and yield, and vigorously promotes and applies greenhouse insecticidal lamps, which will help promote the green ecological development of facility agriculture and improve the ecological benefits of facility agriculture in various regions. Economic and social benefits promote the rapid development of characteristic agriculture in various regions. Marine Electro-hydraulic Windlass The windlass is installed on the main deck of the ship's bow, which is used for the ship to lift the anchor and drop the mooring cable.

Windlass can be divided into manual, electric, hydraulic, pneumatic, etc. according to the driving form.
The windlass can be divided into several specifications such as φ12--φ120mm according to the diameter of the anchor chain.
Windlass can be divided into single-sided and double-sided according to the distribution of drums.
The windlass is mainly composed of base, bracket, chain wheel, brake, chain wheel, gearbox, electric control system (except manual windlass), etc. Electric windlasses have electric motors, and hydraulic windlasses have hydraulic pump stations.
The main technical indicators of the windlass include the diameter of the anchor chain, the nominal speed of the anchor, the rated load, the supporting load, several levels of speed change, electrical system, etc. The installation of the windlass on the ship should ensure that the wrap angle between the anchor chain and the sprocket is 117-120°.
Electric windlass
The electric motor directly drives the windlass, and the drive shaft is driven by the gear box to work, and the structure is simple; it is generally suitable for windlasses with an anchor chain diameter of 16mm-93mm.
hydraulic windlass
It is suitable for windlass with anchor chain diameter of 16mm-120mm. Hydraulic windlasses are also called electro-hydraulic windlasses. It drives the oil pump with a motor, drives the motor with high-pressure oil, and then drives the transmission gear through a reducer (or no reducer). To make the windlass run, its structure is relatively compact and its volume is small. Now there has been an automatic hydraulic windlass, which is equipped with an anchor chain length sensor. When the anchor chain needs to be thrown out, the windlass will automatically stop; , can automatically decelerate; the anchor will automatically stop when it enters the anchor chain drum and is properly received.
