Production of pollution-free peppers, when pests and diseases occur, it is necessary to use chemical pesticides in a timely and reasonable manner, and chemical pesticides should be used correctly, but the following four points should be used when using:
Do not take insurance drugs. It is necessary to investigate the law of the occurrence of pests and diseases, and timely apply the drugs to the weak resistance of the bacteria and pests, which can reduce the number of prevention and control, and can also receive the best control effect. You must not blindly fight the insurance drugs, three days and a small dozen, seven days a dozen, so that the pepper is seriously polluted.
Improve control techniques. The application of whole field application and whole plant application is the key application of the pest area, and the local application of the plant not only greatly improves the effect, but also saves the dosage. Choose pesticide varieties.
It is necessary to select high-efficiency, low-toxicity and low-residue pesticides, such as dimethoate, trichlorfon, dichlorvos, anti-carboside, chlorothalonil, carbendazim, Jinggangmycin, and rust. It is strictly forbidden to use organochlorine, organic mercury preparations and highly toxic and highly residual pesticides such as methamidophos, carbofuran, methyl 1605, 1059, Suhua 203, 3911. These pesticides are extremely toxic to humans and animals. Rational use of drugs.
Rotate medication and mix it reasonably. Control the frequency and concentration of medication, and observe the safety interval for at least 10 days. Control pesticide residues to meet national standards and pollution-free ecological environment to ensure human and animal safety.

1. Components of dust ring:
Polyurethane, rubber
2. Purpose and function of dust ring:
The dust ring is mainly used to remove dust, sewage and other dirt attached to the piston rod exposed on the external surface of the cylinder and prevent external dust and sewage from entering the hydraulic system. It is suitable for occasions with severe dust and high temperature.
3. Use position of dust ring:
Connection between guide sleeve and piston rod
4. Working principle of dust ring:
1. It has very good scraping effect.
2. Excellent slip performance, high wear resistance and shape stability.
3. It is preferred to be used in hydraulic systems with medium to high loads without creeping effect.
4. Wide temperature application range and good chemical stability (depending on the O-ring material)
5. It is suitable for occasions with severe dust and high temperature.
5. What effects will be caused by improper use or operation of dust ring:
1. Improper selection of cavity support material will wear the cavity and piston rod.
2. The size of the friction pair is inappropriate, causing wear.
3. Improper thread guide angle of cylinder barrel and piston end wear the sealing ring.
4. The seal ring is worn due to improper installation guide angle of the seal.
5. The surface of cavity and piston rod is rough, with scratches and worn seals.
