The Root Cause of Hydraulic Cylinder Drift

A popular misconception involving hydraulic cylinders is that if the piston seal is leaking, the cylinder will drift. While a leaking piston seal can be the root cause of cylinder drift, the physics involved are often misunderstood. Fact is, if the piston seal is completely removed from a double-acting cylinder, the cylinder is filled with oil and the ports are plugged, the cylinder will hold.

Understanding PCP Airgun Power Factors

 · This would be the maximum usable dwell (aka duration, the time the valve is open), and it will depend on the pellet weight, barrel length, and other factors. Let's back up a minute… In a conventional PCP, with a "knock open" valve, the valve is held closed mostly by the air pressure inside it (assisted by the valve spring).

Compression and Vacuum

Vacuum is created when each piston travels down the cylinder with the intake valve open and the throttle plate closed. It will change drastically as the engine is running at different RPM and load conditions. It will also change if the compression in a cylinder is lost, or there are air ….

BOOK 2, CHAPTER 8: Directional Control Valves

A 3-position, 4-way valve stops an actuator or allows it to float. The 4-way function is a common type of directional control valve for both air and hydraulic circuits. A 3-position, 4-way valve is more common in hydraulic circuits. The 5-way valve is found most frequently in air circuits. A 5-way valve performs the same function as a 4-way valve.

Control Valve Working Principle

Control valves are valves used to control conditions such as flow, pressure, temperature, and liquid level by fully or partially opening or closing in response to signals received from controllers that compare a "setpoint" to a "process variable" whose value is provided by sensors that monitor changes in such conditions.. Control Valve is also termed as the Final Control Element.

Air Suspension Load Scales

The air suspension system is controlled by the height control valve by maintaining the optimal ride height between the carrying bed of the vehicle and the axles. When weight is applied or removed from a vehicle, the ride height changes and triggers the height control valve to increase or decrease the air pressure into the system to return to.

Pneumatic Solenoid Valves

These valves close all ports in the off position to stop equipment in a locked position with air pressure holding it in place. Often used to extend and then retract a cylinder at different speeds, they create two actions and have two exhaust ports, which allows you to control the speed of each action by attaching a flow control valve to each exhaust port.

Spring Training: Understanding Valvespring Pressure

 · The valve spring pressure measurements you will see are what it has for seat pressure and open pressure. Seat pressure comes from the load that is placed on a valve when it's seated in the closed position. Open pressure is how much load is on a valve when it's at the highest open point and it's being forced to close.

HVAC Design Overview of Variable Air Volume Systems

As the load decreases in a particular zone, the VAV air valve throttles the airflow matching the space requirements. Also when there is a sudden increase in load, the temperature sensor located in the zone will detect a rise in temperature and request the VAV box to open the air valve and increase the amount of cool air ….

In modulating mode the compressor would use 90% of full load power. For load/unload with minimal air storage (1 US Gal per cfm), the compressor would use about 92% of full power. By increasing the air storage to 10 US Gal per cfm, the load/unload compressor will use about 77% of full power.
