Ruber Expansion Joints can reduce vibration and noise, and compensate thermal expansion and contraction caused by temperature change. It is widely used in various pipeline systems.

The pressure control knob on a pressure-cycled ventilator will determine the: A. Pressure at which inspiration ends B. Gradient from the artificial airway to the alveoli C. Effort required to initiate gas flow D. Pressure required to activate the pop-off mechanism

The main functions of the rubber expansion joint include relieving the pressure change of the pipeline system, compensating the influence of the pipeline on temperature change, vibration, installation deviation, and reducing the noise and vibration transmission.

1. The fluid coupling has the function of shock mitigation and torsional vibration isolation. 2. The Hydro-Coupling can improve the starting capacity of the engine, so that it can start with load or no load. 3. The fluid coupling has strong adaptability to the environment and can work in cold, wet, dust and explosion-proof environments.

Nash liquid ring pumps are positive displacement machines achieve compression using a simple design and working principle. The seal liquid forms the ring inside a pump body as the rotor spins creating small chambers for gas to be trapped. The axis of the rotor is eccentric from the body allowing the liquid to almost fill, and then almost empty each rotor chamber during a single revolution, forming the compression of the gas for the pumping action.  Vacuum inlet and atmospheric discharge ports provide flow paths for the gas mixture being handled. The heat of compression of the gas is dissipated into the seal liquid, and some of the liquid flows out to discharge. The exhaust gas and residual water discharge is separated from the gas stream and directed to the house exhaust and returned to the pump respectively. Seal fluid is replaced by a constant flow of cooler seal fluid.

What are the applications for screw blowers? 😀 😎 1.the use of a certain pressure of wind pressure blowing / stirring / blowing objects to achieve a certain process requirements. Such as: flow chemical, homogenization process and pneumatic conveying. 🤓 2.the use of airflow to take away the object surface heat to cool, or take away the object surface moisture to dry. Such as: blast cooling, blast drying. 👤 3.the use of oxygen in the air, for the work surface to provide sufficient oxygen. Such as: blast combustion, oxidation and desulfurization. 💪 4.the lower pressure of the gas pressurization of the higher pressure, in order to meet the subsequent process requirements. Such as: gas pressurization, etc. Such as gas pressurization.

There are two types of convection. Convection is classified as : (i) free or natural convection and (ii) forced convection. When the circulating currents arise from the heat transfer process itself, i.e., from the density differences arising in turn due to temperature differences / gradients within the fluid mass, the mode of heat transfer is called free or natural convection. Examples of natural convection : 1. Heating of a vessel containing liquid by means of a gas flame situated underneath. The liquid at the bottom of the vessel gets heated, expands and rises because its density has become less than that of the remaining liquid. Cold liquid of higher density takes its place and a circulating current is set up. 2. The flow of air across a heated radiator/heat of a room by means of a steam radiator. When the circulating currents are produced by an external agency such as an agitator in a reaction vessel, pump, fan or blower, the mode of heat transfer is called forced convection. Here fluid motion is independent of density gradients. Example of forced convection : Heat flow to a fluid pumped through a heated pipe. In general, higher rates of heat transfer are obtained in forced convection as compared to natural convection owing to a greater magnitude of circulation in the forced circulation.
