  • Engine Exhaust Back Pressure

    The Swiss VERT program determined maximum back pressure limits in order to allow DPFs to be fitted to a wide variety of equipment [1319]. Table 1 outlines the VERT recommended back pressure limits for a range of engines sizes. The exhaust pressure for large engines was limited to low values due to valve overlap and high boost pressure

  • Relationship of Design Pressure, Test Pressure & PSV Set Point

    MAWP of the equipment is the set point for the relief device. The set point pressure is the pressure at which the valve is forced from its seat. From that initial release to its full discharge there is a 10% increase above set point. While a piping system can use the set point of a pressure relieving device on an equipment item it is connected

  • How It Works: Pressure Loss | Schlumberger

    Jan 08, 2015 · Pressure loss that occurs along the direction of flow in a pipe is caused by fluid friction—both internal in the fluid itself and with the piping surfaces—piping restrictions, or sudden changes in the geometry of the flow path. Thus, pressure loss is directly related to fluid velocity, specific gravity, viscosity, and the pipe interior's size, shape, and roughness.

  • WHAT PRESSURE RADIATOR CAP RATING SHOULD I USE? – …

    We get asked this question daily and it seems most people misunderstand what the pressure cap does. The cap pressure rating has nothing to do with regulating your engine coolant temperature, nor will it make your engine run cooler. Let's take a pan of water and heat it up. The water heats up and boils and 212 degrees. Now let's take a pressure cooker and do the same thing. The water will

  • Fuel Pressure Explained - Injector Dynamics

    Effective pressure is what injector flow rate is ultimately based off of. When an engine is idling, there is a vacuum in the intake manifold. This vacuum pulls fuel out of the injectors, and increases the effective pressure across the injector to a pressure higher than the rail pressure itself. When a supercharged or turbocharged vehicle is in

  • How to increase pressure in a hydraulic system - Quora

    Answer (1 of 3): One way is to use a pump with a higher pressure rating. The pressure in a system is, first and foremost set by the load. If the pump cannot produce the pressure the load requires, if it's a fixed displacement pump, then the system relief valve limits maximum pressure. That valve

  • What are the reasons for the slow action of excavator

    Because the excavator works with soil most of the time, the piston of the main pump regulator is easy to be stained with oil, which causes the piston to block, reduces the pump pressure of the main pump, reduces the output power, and makes the excavator move slowly.

  • Back pressure - Wikipedia

    Back (or backpressure) is a resistance or force opposing the desired flow of fluid through pipes, leading to friction loss and pressure drop.The term back pressure is a misnomer, as pressure is a scalar quantity, so it has a magnitude but no direction.The fluid is what is directed, tending to flow away from high-pressure regions and toward low-pressure regions.

  • The Hydraulic Pump - How Caterpillar Backhoe Loaders Work

    In a backhoe, power is just flow rate multiplied by hydraulic pressure. The pressure is determined by the operation being performed -- lifting heavy objects or busting through hard ground requires higher pressure than does moving an empty bucket. Relief valves determine the maximum pressure in the hydraulic system.
