The control valve is a device which directs the fluid to the actuator. This device would comprise steel or cast iron spool which is positioned inside of housing. The spool slides to different locations inside the housing. Intersecting channels and grooves direct the fluid based on the spool's position.
The spool is centrally situated, help in place with springs. In this particular location, the supply fluid can be blocked and returned to the tank. If the spool is slid to one direction, the hydraulic fluid is routed to an actuator and provides a return path from the actuator to tank. If the spool is transferred to the other direction, the supply and return paths are switched. When the spool is allowed to return to the neutral or center location, the actuator fluid paths become blocked, locking it into place.
Typically, directional control valves are designed so as to be stackable. They generally have one valve per hydraulic cylinder and a fluid input which supplies all the valves within the stack.
To be able to prevent leaking and tackle the high pressure, tolerances are maintained extremely tight. Normally, the spools have a clearance with the housing of less than a thousandth of an inch or 25 µm. In order to prevent jamming the valve's extremely sensitive parts and distorting the valve, the valve block will be mounted to the machine' frame by a 3-point pattern.
The position of the spool can be actuated by mechanical levers, hydraulic pilot pressure, 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 controls the stack of directional control valves by capacity and flow performance. Several of these valves are designed to be proportional, like a valve position to the proportional flow rate, whereas some valves are designed to be on-off. The control valve is amongst the most pricey and sensitive parts of a hydraulic circuit.
In the material handling trade counterbalance forklifts are very common pieces of equipment. They can be commonly found in warehouses and factories all around the world. The leading lift truck makers like for example Linde, Toyota and Mitsubishi all make counterbalance forklifts. They are obtainable in a range of fuel options like diesel, electric or gas. Usually, a counterbalanced forklift truck includes the following parts:
The Cab is the area which has a seat intended for the person operating it and houses the control pedals, levers, steering wheel, a dashboard containing operator readouts and different switches. The Truck Frame is the foundation of the machinery that each of the different parts, mast and counterweight, the axles, wheels, power source are all attached to. The frame can likewise have hydraulic fluid tanks and fuel tanks constructed as part of its assembly. The Mast is the vertical assembly that does most of the work raising and lowering the forklift's load.
Made of heavy iron the counterweight is connected to the rear of the forklift frame. The purpose of the counterweight is to balance the weight being lifted and transferred. Utilizing an electric lift truck, the huge lead-acid battery itself could work as part of or all of the counterbalance. The Power Source can have an internal combustion engine which can be powered by gasoline, LP gas, CNG gas or diesel. Electric forklifts are driven by either fuel cells which provide power to a battery or electric motors. The electric motors could be either AC or DC kinds.
Attachments used for the forks differ in the type of application they allow the forklift to perform. Attachments comprise: carpet poles, pole handlers, side shifters, multipurpose clams, carton clamps, slip-sheet attachments, fork positioners, roll clamps and container handlers. Many manufacturing businesses will specially customize an attachment to be able to satisfy a client need.
When needing to park pallets closely together, the counterbalance lift truck is the best electric lift designed for the job. There are lots of advantages to using a counterbalance lift rather than fork-over and straddle-leg designs. They do have a few disadvantages though. A counterbalanced forklift could lift pallets directly off the floor in view of the fact that there are no stabilization legs to interfere. The main disadvantage of this model of forklift is that the lift height and the weight capacity would usually be less than the various kinds.
