The main type of Tape Measure is steel tape, followed by fiber tape, which is the tape that everyone often sees. Many people say it is a cloth ruler, and there is also a waist measurement ruler (tailor ruler/clothing ruler belong to this category). In southern China and Hong Kong, the tape measure is usually referred to as a soft ruler or a pull ruler. The material is PVC plastic and glass fiber, which can prevent the tape from being stretched during use.

Pneumatic diaphragm pump the main application
Pneumatic diaphragm pump is a new type of conveying machinery, is currently the most novel kind of pump (the sentence used in 2001 or so). The use of compressed gas as the power source, for a variety of corrosive liquids, with particles of liquid, high viscosity, volatile, flammable, highly toxic liquid can be smoked exhausted. Pneumatic diaphragm pump has four materials: plastic, aluminum, cast iron, stainless steel. Pneumatic diaphragm pump according to different liquid medium to identify nitrile rubber, neoprene, fluorine rubber, PTFE, polyhexamethylene. To meet the needs of different users. Placed in a variety of special occasions, used to pump a conventional pump can not be aspirated medium, have achieved satisfactory results. 1. Due to the use of air as power, so the flow with the back pressure (outlet resistance) changes and take the initiative to mediate, suitable for medium and high viscosity fluids. Centrifugal pump operating point and therefore set the water as a benchmark, if used for slightly higher viscosity fluid, it is necessary to support reducer or frequency converter, the cost has greatly improved, the same is true for the gear pump. 2. In hazardous, corrosive materials handling, the diaphragm pump can completely separate the material from the outside world. 3. Pneumatic diaphragm pump can be applied to do not want the media is contaminated occasions. 4. Pneumatic diaphragm pump can be used to transport less stable chemical fluid, such as: photographic materials, flocculation and so on. This is because diaphragm pumps have low shear forces and little physical impact on the material. 5. In a flammable and explosive environment with pneumatic pump reliable and low cost, such as fuel, gunpowder and other media delivery, because: First, the ground can not produce sparks after grounding; second, no heat during work, the machine is not Will overheat; Third, the fluid will not overheat because the pneumatic diaphragm pump agitates the fluid to a minimum. 6. In the abominable center of the site, such as construction sites, industrial and mining wastewater discharge, due to the impurities in the sewage and a large composition, the pipeline easy to infarction, so that the pump to form an overloaded environment, the motor heat vulnerable. Pneumatic diaphragm pump through the particles and the flow rate can be adjusted, the initiative to stop the pipeline when the infarction to delay. 7. Other pneumatic diaphragm pump easy to move small size, unnecessary foundation, accounting for the ground is extremely small, easy to install economy. Can be used as mobile material pump.
