  • Dynamic Flow Balancing Valve

    Function: The dynamic flow balance valve keeps the flow constant between 31-600KPa. Role: Keep the flow through the valve constant. Theory: When the incoming flow pressure P1 increases, the sleeve of the valve sleeve moves downward, compressing the spring inside the valve bladder, and reducing the flow area of the valve hole at the bottom of the valve bladder, that is, reducing the Kv value of ...

  • Plastic Pressure Switch

    Pressure switch is a simple pressure control device. When the measured pressure reaches the rated value, the pressure switch can give an alarm or control signal. ...

  • Digital Pressure Gauge

    [Technical Name] Digital pressure gauge [Background] The energy storage equipments of the gun, such as the reclaimer, balancer and accumulator, have greater working pressure. If the pressure can not meet the technical requirements, the gun can not operate normally. Therefore, in the daily service of artillery, it ...

  • Improved Particle Counting Accuracy in Manifold Monitoring

    Abstract Many particle counter users are unaware that – during traditional manifold sampling – the monitor undercounts the ambient particle concentration. Because of the additional vacuum created by the manifold pump, the particle concentration is substantially lower in the air sampled than in the ambient cleanroom air. Unless the system adjusts appropriately, this ...

  • Gas mixing and blending equipment – Case Study

    How They Work A specific gas blend within a chamber must be produced by a procedure known as ideal gas mixing (or gas blending). In this example, synthetic air composition is maintained at a mix ratio of 78% N2, 21% O2 and 1% Ar. A miniature Human/Machine Interface (HMI) with LCD touch screen monitors and controls the system automatically. The HMI communicates to ...

  • High voltage switchgear SF6 maintenance – Case Study

    Just like the main circuit breaker in your home, city grids have main on/off switches called switchgears. When these high voltage switchgears open or close, huge "lightning-like" arcs of electricity are created. If not maintained correctly, these sparks can causewidespread power outages and pose a safety risk. To avoid these dangerous sparks, power companies have traditionally filled the sealed ...
