Respirators are used more and more widely. Respirators are widely used in industrial and medical applications. They are mainly used in fire-fighting, chemical, shipbuilding, petroleum, smelting, factories, mines, etc. Respirators are often used under occupational safety guidelines. Workers are Before using the respirator, professional training is also required. In some workplaces, such as asbestos, or other harmful toxins or harmful chemicals are often required to wear a mask. And individuals are protected from chemical or biological hazards. After other use respirators include medical conditions such as severe asthma or chronic obstructive pulmonary disease (COPD).
In addition, there are also widely used underwater diving equipment, fire fighting fire extinguishers. Widely used in hotels, escape breathing apparatus in public places, emergency escape breathing apparatus.
A medical ventilator is an instrument for breathing a patient. The use of such a device also requires training or instruction before it can be properly used and maintained. When the patient suffers difficulty in breathing, the user wears a simple medical respirator with the help of medical staff. This kind of operation requires the relevant documents for the operation of simple respirator for medical use. Before the use, it must also carry out some tests on the patient, including respiratory and pulmonary function tests, and other physical conditions, as well as regular maintenance, maintenance, and inspection of the respirator. Working condition to ensure that the instrument is working properly
In hot die forging press, the automatic line for host is active the development direction of forging crankshaft production, the production line will be widely used precision shearing blanking, forging (cross wedge rolling) blocking, medium frequency induction heating, finish hydraulic press and other advanced technology, and equipped with robots, conveyor belt,back mold device of the turntable in auxiliaries, such as formation of flexible manufacturing system (FMS).
Through FMS, the work piece and mold can be replaced automatically and parameters can be adjusted automatically.Display and record the data of the thickness and maximum pressure of the Forging Parts and compare it with the fixed value. Select the optimal deformation amount to obtain the quality products.The whole system is monitored by the central control room to realize unmanned operation.The crankshaft forged by this forging method has the full fiber property of internal metal streamline and can increase the fatigue strength by more than 20%.
