The use of solar insecticidal lamp to kill insects has the advantages of environmental protection, pollution-free, labor saving, etc. It is very suitable for large-scale promotion and application in pollution-free agricultural production. If supplemented with biological pesticides to control pests, it can fully meet the requirements of the State Forestry Administration. Caterpillars and other leaf pests require pollution-free control, which can play a very important role in the protection of environmental resources and the sustainable development of agriculture. Economic, ecological and social benefits are very significant. In addition, in recent years, with the continuing hot tourism, solar insecticidal lamps have also been applied to some areas with frequent cultural activities in key scenic spots. Its application has effectively avoided the impact of chemical control on tourists and met the development of modern society. need.

Solar insect killer

With the application of solar insect killer lamps becoming more and more widely used, the safe use of solar insect killer lamps is increasingly concerned by users and users. To increase the safety of solar insect killer lamps, let's talk about solar energy killers. The safe use of insect lamps.

1. Establish a responsibility system, unified management In the process of using solar insecticidal lamps, it is necessary to fix special person management, establish a management system that combines people and lights, and special persons are responsible for the opening, closing, collection, recording and analysis of solar insect light. Processing, etc., regularly clean the solar insecticidal lamp and check the working status of the insecticidal lamp.

2. Eliminate potential safety hazards and prevent the loss and damage of solar insect killer lamps.
In the process of using solar insecticidal lamps, it is necessary to focus on the investigation of potential safety hazards of solar insecticidal lamps to prevent the loss of power cords and the loss of insecticidal lamps.

3. Appropriately appraise the application scope and types of solar insecticidal lamps In areas where insect pests are strong, the insect report light can be set for monitoring and warning for a long period of time. For some inconveniently connected areas, the use of solar insecticidal lamps is an ideal choice. . In addition, in places with better economic conditions, insecticidal lamps with higher configuration and higher degree of automation can also be used to save manpower.

In short, the safe use of solar insecticidal lamps must establish strict regulations and requirements. The staff also need to be familiar with the working process of solar insecticidal lamps and be familiar with their use methods and precautions in order to achieve the purpose of safely using solar insecticidal lamps. , The advantages and effects of solar insecticides in the prevention and control of green insect pests have been brought into play.

Stud Bolt

In Petro and chemical industry for flange connections Stud Bolts and Hex Bolts are used

The quantity of bolts for a flange connection will be given by the number of bolt holes in a flange, diameter and length of bolts is dependent of flange type and Pressure Class of flange.

Stud Bolt length are defined in ASME B16.5 standard. The length in inches is equal to the effective thread length measured parallel to the axis, from the first to the first thread without the chamfers (points). First thread is defined as the intersection of the major diameter of the thread with the base of the point.

1) Standards: Based on DIN & ANSI & JIS & IFI

and per drwing

2) Material: carbon steel, alloy steel, stainless steel

3) bolt Size: M4-M42,3/8"--7/8"

4) bolt Surface: Plain,Zinc ,HDG,DAC,Geomet

5) bolt Thread: UNC, UNF, Metric Thread

6) bolt Quality control : ISO 9001

7) bolt Package : Small box ,Poly Bag,Carton+Pallet
