1, the selection of goggles should be selected by the product inspection agency inspection of qualified products;
6. Prevent heavy fall and heavy pressure, and prevent hard objects from rubbing lenses and masks.
Two types of use of safety protective glasses: amber safety glasses,safety glasses,dark safety glasses,cool safety glasses, anti fog safety glasses Behappy Crafts (suzhou)Co.,Ltd , https://www.jshaoyue.com
2. The width and size of the goggles should suit the user's face shape;
3, lens wear rough, lens frame damage, will affect the vision of the operator, should be replaced in time;
4. Goggles should be specially used to prevent eye diseases;
5, the filter and protection of welding goggles should be selected and replaced according to the requirements of the specified operation;
A. Anti-cementing debris
Mainly used to prevent metal or sand debris and other mechanical damage to the eyes. Lenses and frames should be of solid construction and resistant to impact. The frame of TDAF001 sky shield is equipped with a shielding edge, and there shall be ventilation holes on it. Protective lens can choose toughened glass, adhesive glass or copper wire mesh protective lens.
B. Antichemical solution
Mainly used to protect the eyes from chemical damage caused by irritating or corrosive solutions. Ordinary flat lens can be used, and the frame should be covered to prevent the solution from splashing into. Usually used in laboratories, hospitals and other places, general medical glasses can be universal
Aluminum pneumatic diaphragm pump is a new type of conveying machinery, is currently the most novel kind of pump. The use of compressed air as the power source for a variety of corrosive liquids, with particles of liquid, high viscosity, volatile, flammable, highly toxic liquids, can be exhausted exhausted, the following simple analysis of aluminum pneumatic Diaphragm pump features it! As follows: 1, aluminum pneumatic diaphragm pump without irrigation, suction up to 7m, lift up to 50m, outlet pressure ≥ 6kgf / c ㎡. Flow-wide, through the good performance, allowing QBY pneumatic diaphragm pump can both pumping liquid flow, but also transport some difficult to flow medium, with self-priming pump, submersible pump, shield pump, mud pump and impurity pump and other transport machinery Many advantages. 2, aluminum pneumatic diaphragm pump without rotating parts, there is no diaphragm will be pumping the pumping medium and pump moving parts, working medium completely separated, the media will not be transported to the outside leakage. Therefore pumping toxic, volatile or corrosive media, will not cause environmental pollution and endanger personal safety. 3, the largest particles, the diameter of 10mm pumping mud, impurities, the pump wear little. 4, head, flow through the valve opening to achieve stepless adjustment. (Air pressure adjustment between 1-7kg / c ㎡). 5, aluminum pneumatic diaphragm pump is simple in structure, less wearing parts, the pump structure is simple, easy installation, maintenance, pump delivery medium will not come into contact with the valve, connecting rod and other moving parts, unlike other types of pump Rotor, piston, gear, blades and other parts of the wear and tear and gradually decline in performance. 6, aluminum pneumatic diaphragm pump without electricity, safe and reliable in flammable and explosive places. 7, can be immersed in the media work. 8, aluminum pneumatic diaphragm pump without oil lubrication, even idling, the pump has no effect. This is a big feature of the pump. 9, aluminum pneumatic diaphragm pump easy to use, reliable, open and close the pump simply open and close the gas valve, even if due to unexpected conditions and a long absence of medium-run or sudden shutdown, the pump will not be damaged, once Overload, the pump will automatically shut down, with self-protection, when the load back to normal, but also automatically start running.
