The function of directional control valves is to be able to direct the fluid to the desired actuator. Usually, these control valves comprise a spool situated in a housing made either from cast iron or steel. The spool slides to different places inside the housing. Intersecting channels and grooves route the fluid based on the spool's position.
The spool is centrally located, help in place by springs. In this particular position, the supply fluid could be blocked and returned to the tank. If the spool is slid to one direction, the hydraulic fluid is directed to an actuator and provides a return path from the actuator to tank. When the spool is transferred to the other direction, the supply and return paths are switched. Once the spool is enabled to return to the center or neutral place, the actuator fluid paths become blocked, locking it into position.
The directional control is usually designed to be stackable. They generally have a valve for each hydraulic cylinder and a fluid input that supplies all the valves in the stack.
To be able to prevent leaking and tackle the high pressure, tolerances are maintained extremely tight. Typically, the spools have a clearance with the housing of less than a thousandth of an inch or 25 µm. To be able to prevent distorting the valve block and jamming the valve's extremely sensitive components, the valve block would be mounted to the machine' frame with a 3-point pattern.
The position of the spool could be actuated by mechanical levers, hydraulic pilot pressure, or solenoids which push the spool right or left. A seal allows a portion of the spool to protrude outside the housing where it is easy to get to to the actuator.
The main valve block controls the stack of directional control valves by flow performance and capacity. Some of these valves are designed to be proportional, as a proportional flow rate to the valve position, whereas other valves are designed to be on-off. The control valve is amongst the most sensitive and costly parts of a hydraulic circuit.
Counterbalance lift trucks are popular pieces of equipment in the material handling business. They are really popular machines found in warehouses and factories around the globe. The leading forklift makers like Toyota, Mitsubishi and Linde all construct counterbalance lift trucks. They are accessible in different fuel choices like electric, gas or diesel. Normally, a counterbalanced forklift truck consists of the following parts:
The Cab is the section which has a seat intended for the individual operating ti and houses the steering wheel, a dashboard containing operator readouts, control pedals, levers and different switches. The Truck Frame is the base of the machine that each of the various parts, the axles, wheels, power source, mast and counterweight are all connected to. The frame could even 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 rear of the forklift truck frame. The counterweights' purpose is to balance the weight being lifted. With an electric forklift, the huge lead-acid battery itself could work as part of or all of the counterweight. The Power Source could have an internal combustion engine that can be powered by diesel, gasoline, LP gas or CNG gas. Electric lift trucks are powered by either fuel cells that provide power to electric motors or a battery. The electric motors can be either DC or AC types.
Attachments designed for the forks differ in the kind of application they allow the forklift to perform. Attachments consist of: carton clamps, slip-sheet attachments, fork positioners, roll clamps, container handlers, carpet poles, pole handlers, side shifters and multipurpose clams. Numerous manufacturing companies would specifically modify an attachment in order to meet a customer requirement.
When needing to park pallets closely together, the counterbalance forklift is the ideal electric lift meant for the task. There are lots of benefits to using a counterbalance lift rather than fork-over and straddle-leg designs. They do have a few disadvantages however. A counterbalanced forklift can carry pallets directly off the floor for the reason 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 styles.
