The control valve is a tool that routes the fluid to the actuator. This device will comprise steel or cast iron spool which is positioned inside of housing. The spool slides to different positions inside the housing. Intersecting channels and grooves direct the fluid based on the spool's location.
The spool is centrally located, help in place by springs. In this particular location, the supply fluid could be blocked and returned to the tank. When the spool is slid to a direction, the hydraulic fluid is routed to an actuator and provides a return path from the actuator to tank. If the spool is moved to the other direction, the supply and return paths are switched. As soon as the spool is enabled to return to the center or neutral location, the actuator fluid paths become blocked, locking it into position.
The directional control is typically made to be stackable. They generally have one valve for every hydraulic cylinder and one fluid input that supplies all the valves within the stack.
To be able to prevent leaking and handle the high pressure, tolerances are maintained extremely tight. Usually, the spools have a clearance with the housing of less than a thousandth of an inch or 25 µm. So as to avoid jamming the valve's extremely sensitive components and distorting the valve, the valve block will be mounted to the machine' frame by a 3-point pattern.
The location of the spool could be actuated by hydraulic pilot pressure, mechanical levers, or solenoids which push the spool right or left. A seal enables a part of the spool to protrude outside the housing where it is accessible to the actuator.
The main valve block is normally a stack of off the shelf directional control valves chosen by capacity and flow performance. Some valves are designed to be on-off, whereas others are designed to be proportional, as in valve position to flow rate proportional. The control valve is among the most sensitive and pricey components of a hydraulic circuit.
In the material handling business counterbalance forklifts are extremely common pieces of machinery. They can be normally used in factories and warehouses all around the globe. The leading lift truck producers like for example Toyota, Mitsubishi and Linde all make counterbalance forklifts. They are presented in a variety of fuel options like gas, diesel or electric. Usually, a counterbalanced forklift truck consists of the following parts:
The part meant for the operator called the "cab" and houses all of the a dashboard which contains certain readouts, levers, pedals, steering wheel plus various switches. The frame of the forklift is the base for the various components of the machinery including the mast and counterweight, the power supply, the wheels and the axles. The frame can 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 lowering and raising the forklift's load.
The counterweight is a heavy mass of cast iron which is connected to the back of the forklift truck frame. The counterweights' purpose is to offset all the cargo being carried. With an electric forklift, the huge lead-acid battery itself can serve as part of or all of the counterweight. The Power Source could have an internal combustion engine which can be powered by gasoline, LP gas, CNG gas or diesel. Electric lift trucks are powered by either fuel cells that provide power to a battery or electric motors. The electric motors may be either AC or DC types.
Attachments designed for the forks vary in the kind of application they allow the lift truck to carry out. Attachments comprise: multipurpose clams, carton clamps, slip-sheet attachments, fork positioners, roll clamps, container handlers, carpet poles, pole handlers and side shifters. A lot of manufacturing companies will specially customize an attachment in order to satisfy a client need.
When needing to park pallets closely together, the counterbalance forklift is the ideal electric lift utilized for the task. There are a lot of benefits to using a counterbalance lift instead of straddle-leg and fork-over designs. They do have several disadvantages though. A counterbalanced lift truck could carry pallets straight off the ground since there are no stabilization legs to interfere. The main drawback of this unit of forklift is that the lift height and the weight capacity will generally be less compared to the various styles.
