4. Check to make sure plant is secured before leaving the premise. 3-2.2 BACKWASH SYSTEM Backwashing of the filter consists of up flow water wash followed by a rinse cycle. Backwashing is normally run automatically by setting the timer at predetermined interval to activate backwash cycle. The filter can also be manually backwashed.
The flow of water to the oil cooler of governor oil system is maintained automatically by an electromagnetic valve and globe valve which facilitates repairs and servicing. A pressure gauge located after the electromagnetic valve indicates the pressure of the cooling water being fed to the oil cooler. Another pipe carries technical water to the guide bearing oil cooler, on the outlet pipe from the guide bearing cooler, a flow failure relay has been provided to give a signal in case of flow-failure through the pipe. The outlet pipe discharges water from the cooler into the drainage channel. 2.4.1 Oil pipe lines of the governing
In order to function, the motion detection system is comprised of a capacitive sensor, a motion sensor, a wireless signal, and a solenoid valve. First and foremost, the capacitive proximity sensor is the medium through which the AAA system is activated and deactivated. Thus, it is essential to obtain a comprehensive understanding of the sensor and its working principle (refer to figure 1 in Appendix A). The capacitive sensor is a point-level sensor, which indicates whether the substance is above or below the sensing point. A sensor that is designed for point level detection will detect liquid at a certain point in a tank or vessel.
To adjust the liquid level, liquid flow from the chimney tray is sent off to the bottom section through the control valve which similar to the conventional distillation column used. Through this manner, the vapor split ratio control can be accomplished intentionally
The agitation speeds were manually set and maintained throughout the course of experimentation. The reactor has an anchor type blade stirrer which was used for slurry agitation in all the tests conducted in this investigation. The pressure inside the reactor was monitored using a fitted pressure gauge. In order to obtain the desired pressure in the reactor vessel, the pressure of oxygen gas added to the reactor vessel was regulated by the pressure regulating valve fitted to the oxygen
hat is used to impart energy to a fluid through centrifugal force. Thus, stripped of all refinements, a centrifugal pump has two main parts: (1) a rotating element, including an impeller and a shaft, and (2) a stationary element made up of a casing, casing cover, and bearings. In a centrifugal pump, the liquid is forced by atmospheric or other pressure into a set of rotating vanes. These vanes constitute an impeller that discharges the liquid at its periphery at a higher velocity. This velocity is converted to pressure energy by means of a volute (see Figure 1) or by a set of stationary diffusion vanes (see Figure 2) surrounding the impeller periphery.
Briefly describe the stages of a typical cleaning cycle. 1. Pressure Hold Test: we must make sure the vessel is integral; 2. Water Pre-rinse: remove gross contaminants, dissolve soluble items. It depends what is in the vessel.
The spindle is rotated with mechanasim envoloped through a calibrated spring. The spring’s viscous drag offored by the resin against the spindle is measured by its deflection which in turn and calculated by transducor . Viscosity is measured in units of centipoise. Procedure:- The Viscometer is auto zeroed by removing the spindle and pressing any key. Set speed as designated in product specification.
The multiplexer is used to overlap the input signals and pass them onto the next block. The output from the mux is given to the fuzzy logic controller with rule viewer block. The rules which are written using Fuzzy Inference System (FIS) are loaded to the fuzzy logic controller. The fuzzy logic controller with rule viewer displays the complete fuzzy inference process during simulation. The first input to the valve subsystem is received from the fuzzy controller block and the second input consists of a constant block containing the value 0.5 which is the maximum inflow of the tank.
Then the valve at the bottom of the calibrated tank was closed and noted the time required for the water to rise between two marks using a stopwatch. As soon as the water level reaches the top mark the valve was opened and the energy meter reading was taken. Repeated the whole experiment with by increasing discharge pressure till it reaches the maximum discharge pressure. 4. Observations & Results Energy meter when pump is run empty (kW1) = 0.014 kW Height difference between suction and discharge pressuring tapings (Z) = 93 cm Volume of calibrated tank (V) = 12 ltr Observation
