Pneumatic valve does not work, the failure phenomena and reasons are as follows: 1. No power, no power to the pneumatic valve input, check the input power. 2. The air pressure is low, check the pressure of the air compressor storage tank-the outlet pressure of the pressure reducing valve at the outlet of the air storage tank-the inlet pressure of the pneumatic valve. 3. The solenoid coil is burned out and re

Its hydrocarbon-free suction chamber makes the diaphragm pump particularly suitable as a backing pump with a turbomolecular pump. Even a two-stage diaphragm pump can achieve an ultimate pressure of approximately 5 hPa. For the backing pump of a turbomolecular pump, this is sufficient. The clean vacuum is particularly suitable for analysis and R&D applications. Because there is no gas ballast, the diaphragm pump

Diaphragm vacuum pumps are dry vacuum pumps. The connecting rod driven by the crankshaft moves the diaphragm tensioned between the upper cover and the housing. The space between the upper cover and the diaphragm forms a suction chamber. Diaphragm pumps require inlet and outlet valves to achieve the target gas displacement. A pressure control shutoff valve made of elastomer material constitutes this valve. Since the

The muffler can be divided into three types: resistive muffler, resistive muffler and impedance compound muffler according to the principle and structure of sound elimination. 1. Resistant muffler Resistant muffler is an expansion room, resonance room and other muffler units formed by pipes, partitions and other components inside. Sound waves are reflected and interfered during propagation, reducing the sound ener

We provide muffler. If you are interested in this, please contact us to learn more about muffler. The sound elimination principle of the muffler is to use the appropriate combination of the cavity and the tube to achieve two functions to muffle the sound: one is to use the sudden change of the pipe section (that is, the change of the acoustic impedance) to reflect the sound wave propagating along the pipe back tow

1. The muffler is mainly composed of muffler tube, muffler film, upper and lower sealing plate, rain cap, throttle tube, throttle plate, connecting tube, support, lifting ring, nameplate and other parts. 2. It has the characteristics of convenient installation, good noise reduction effect and long life. 3. The muffler can be independently supported, and can expand freely during operation and shutdown, so that t

The muffler in car of a car is the main component of driving noise treatment. The muffler in car mainly eliminates noise by reducing and attenuating the pulsation of exhaust pressure. According to the principle of interference, the muffler of the beater has two basic ways of silencing: absorption and reflection. 1. Absorption muffler: reduce the energy of the exhaust gas by the friction between the glass fiber, st
