The function of directional control valves is to be able to direct the fluid to the desired actuator. Normally, these control valves comprise a spool located inside of a housing made either from steel or cast iron. The spool slides to different locations within the housing. Intersecting channels and grooves route the fluid based on the spool's location.
The spool is centrally located, help in place with springs. In this particular location, the supply fluid can be blocked and returned to the tank. When the spool is slid to a direction, the hydraulic fluid is directed to an actuator and provides a return path from the actuator to tank. If the spool is transferred to the other side, the return and supply paths are switched. Once the spool is allowed to return to the center or neutral location, the actuator fluid paths become blocked, locking it into position.
The directional control is typically intended to be stackable. They normally have one valve for every hydraulic cylinder and a fluid input which supplies all the valves within the stack.
To be able to prevent leaking and handle the high pressure, tolerances are maintained really tight. Normally, the spools have a clearance with the housing of less than a thousandth of an inch or 25 µm. To be able to avoid distorting the valve block and jamming the valve's extremely sensitive parts, the valve block will be mounted to the machine' frame by a 3-point pattern.
The location of the spool could be actuated by mechanical levers, hydraulic pilot pressure, or solenoids that push the spool left or right. A seal allows a portion of the spool to stick out the housing where it is accessible to the actuator.
The main valve block is usually a stack of off the shelf directional control valves chosen by capacity and flow performance. Some valves are designed to be on-off, while others are designed to be proportional, as in valve position to flow rate proportional. The control valve is among the most sensitive and expensive components of a hydraulic circuit.
In the material handling business counterbalance forklifts are really common pieces of equipment. They can be normally found in factories and warehouses all around the globe. The leading lift truck makers such as Mitsubishi, Linde and Toyota all construct counterbalance forklifts. They are accessible in a variety of fuel choices like for instance electric, gas or diesel. Typically, a counterbalanced forklift truck contains the following components:
The Cab is the area that has a seat for the person operating it and houses the steering wheel, a dashboard containing operator readouts, control pedals, levers plus a variety of switches. The Truck Frame is the foundation of the equipments that each of the different parts, power source, mast and counterweight, the axles, wheels are all attached to. The frame could also have fuel tanks and hydraulic fuel tanks constructed as part of its assembly. The Mast is the vertical assembly that does the majority of the work raising and lowering the forklift's load.
The counterweight is a heavy mass of cast iron that is connected to the back of the forklift truck frame. The counterweights' objective is to offset the cargo being lifted. Using an electric forklift, the large lead-acid battery itself can operate as part of or all of the counterweight. The Power Source could have an internal combustion engine that could be powered by CNG gas, diesel, gasoline or LP gas. Electric forklifts are driven by either fuel cells which provide power to electric motors or a battery. The electric motors may be either AC or DC types.
Fork attachments are different types of material handling attachments which are offered including carpet poles, pole handlers, side shifters, multipurpose clams, carton clamps, slip-sheet attachments, fork positioners, roll clamps and container handlers.
When needing to park pallets closely together, the counterbalance forklift is the best electric lift utilized for the task. There are many advantages to using a counterbalance lift instead of straddle-leg and fork-over designs. They do have a few disadvantages however. A counterbalanced lift truck can lift pallets straight off the floor as there are no stabilization legs to get in the way. The main disadvantage of this model of forklift is that the weight capacity and lift height will normally be less compared to the various styles.
