For applications requiring assured and high pressure hydraulic fluid flow, cam-actuated radial piston pumps are highly specialized hydraulic pumps. Though these types of pumps are not usually found in standard cargo trucks on highway trucks, they are common on specialized utility vehicles. Below are some of the particular applications where you might locate a cam-actuated radial piston pump on a highway truck:
Tow Trucks
Winches and booms used for lifting and towing vehicles commonly use high-pressure hydraulic systems in tow trucks. A radial-piston pump activated by a cam may thus be used to operate them more efficiently.
Garbage Trucks
The compactors and lifting mechanisms of garbage trucks that lift waste containers normally work with hydraulic systems. In this case, a radial-piston pump driven by the cam can provide the high intensity required for those activities.
Construction and Utility Trucks
Cam-actuated radial piston pumps could be utilized by some construction or utility trucks fitted with hydraulic cranes, booms or diggers. These assist to run these heavy duty attachments at needed power levels plus control.
Concrete Pumping Trucks
Hydraulic systems move materials through concrete pumping trucks that dispense it onto construction sites. The presence of this device is vital in order to maintain pressure required for smooth movement of concrete.
Fire Trucks
Often fire engines have hydraulic systems to open up extending ladders or for operating other unique equipment. In such instances, a cam actuated radial piston pump can form part of the hydraulic system.
Position within Truck
Where exactly the pump is situated depends upon its application as well as design of the truck. However, most times they are positioned near power take-off (PTO) unit so as to easily tap power from vehicle’s engine directly. For instance; cable fastening is done using frame rail bolts while others have brackets which hold them to protect against debris from road elements like water or dust because they’re mostly found outside the chassis . Cabling and hydraulic lines are used to connect the pump to various actuators and hydraulic cylinders around the truck.
Why Use Cam-Actuated Radial Piston Pumps?
The application of these pumps in high pressure situations is due to their ability to deliver reliably high pressures. Multiple pistons encircling a central cam design that is often used in these pumps makes it possible for them to handle imbalances of pressures than other types of hydraulic pumps. The latter feature is crucial for applications requiring consistent and reliable supplies of hydraulic fluid at high pressures.
Other Factors
However, despite being more costly compared to other forms of hydraulic pumps, cam actuated radial piston pumps are cost effective over time because they are built for durability and performance especially in tough conditions.
In brief, cam-actuated radial piston pumps are not generally available on each highway truck but they are integral in specialized vehicles, which need dependable hydraulics systems operating under high pressure. Most times, this pump is close by a truck engine or PTO unit where mechanical energy gets converted into hydraulic one efficiently for different high-pressure purposes.
