Valve sizing

This paper presents the possible combinations of advantage factors from PFI and GDI system by applying an airassisted injector on Semi-direct Injection System (SDI). Firstly, an adaptor that uses compressed air to improve the atomization of conventional injector and reduce droplet size is made. Secondly, the modifications of intake port by using vortex plate and the other by closing one intake valve increase swirl ratio of in-cylinder air motions which help to form rich mixture around spark plug and lean mixture at other locations.

Bi-reactor open core gasifier was built with the capacity to process approximately 15 kg of briquettes per hour. The reactor was made up of double walled cylindrical body with 300 mm of outer cylinder diameter and 244 mm of inner cylinder diameters excluding the thickness of sheet 6 mm. Both the cylinders were made up of 3 mm M.S. sheet 18 SWG. Another reactor was fabricated with same specifications and both outlets were interconnected. Gate valves were fixed to regulate the air flow rate and control the producer gas.

In our previous study, the small-sized quasi-servo valve using two inexpensive on/off valves was developed and tested. The pressure control type quasi-servo valve was also proposed and tested by using the quasi-servo valve, a pressure sensor and an embedded controller. In this paper, the pressure control type quasi-servo valve is applied to a force control of the pneumatic cylinder, and its control performance is investigated.

Traditionally, blending coals of differing ranks complicates the combustion system design for boilers and requires over-sizing and compromising of optimal performance as individual equipment is required to operate in a non-ideal mode. In such a scenario, effectively, the equipment must try to meet the differing needs of both coals at the same time which means that it won’t be operating as efficiently as would otherwise be the case.

The hydraulic system consists of an oil sump, one or two oil pumps, an air over oil accumulator tank, and piping to the servomotors. Typically, there are two pumps with lead and lag controls so that there is always a backup pump. Some systems will share two pumps between two units so that in an emergency one pump could be used for both units. The accumulator tank is usually sized so that in the event the pumps fail, the gates can still be closed. The size of the valve required to control the large amount of oil...

A Liqui-Mover pump is a positive displacement pressure powered pump with a minimum of moving parts. The pumping action is accomplished using a positive pressure to push the liquid from the pump tank into the return line. The Liqui-Mover pump can handle high temperature and high pressure condensate without difficulty. Liqui-Mover pumps are available in nine sizes. They are available in many configurations, from individual components that are field assembled to complete packaged systems ready for connection to field piping.

Flexible Wedge The flexible wedge gate valve illustrated in Figure 6 is a one-piece disk with a cut around the perimeter to improve the ability to match error or change in the angle between the seats. The cut varies in size, shape, and depth. A shallow, narrow cut gives little flexibility but retains strength. A deeper and wider cut, or cast-in recess, leaves little material at the center, which allows more flexibility but compromises strength.
