Where is the relief valve on a log splitter?
A hydraulic relief valve controls the maximum pressure which can be created by the pump, and is a safety valve. It is usually located within the housing of the directional control valve.
What is an adjustable detent on a log splitter?
This is the next generation in log splitter valves. The detent is usually what wears out and causes valves to fail. This valve allows user to adjust the kick out pressure to what they need and as detent balls and grooves wear.
How do you adjust a hydraulic valve?
Adjust the relief valve by turning the adjuster clockwise until the reading on the gauge builds to the pressure called for on the machine drawings. This is what is known as the valve “cracking” pressure, which is the pressure at which the relief valve starts to open.
How does a log splitter detent valve work?
The detent valve in a log splitter is the central assembly where the unpressurized hydraulic fluid interacts with the pressurized hydraulic fluid, creating the necessary reactions that make the log splitter work in the first place.
How do you adjust the pump on a log splitter?
Twist the screw on the side of the pump clockwise with a flat blade screwdriver to increase pressure, according to the scale printed or embossed on the side. Turning the screw counterclockwise decreases pump pressure. Raise the guards on the sides and back of the splitter to the upright locked position.
How do you adjust a detent valve?
Do the following:
- Turn off the engine.
- Relieve fluid pressure in the system by cycling the control lever a few times.
- Put the control lever in the neutral position.
- Loosen the locking nut (closest to the valve) on the return detent adjustment bolt.
- Turn the bolt clockwise 1/4 turn to tighten the relief spring.
How do you adjust a control valve?
Open a flow control valve by turning it in the counterclockwise direction. Use the recommended number of turns or fractional turn to open the valve for the desired pressure. Set the valve to the desired pressure by turning it to a specific setting, or by measuring with a pressure meter downstream.
What is the purpose of a detent valve?
A hydraulic valve having a detent mechanism engaging the valve to releasably retain the valve in an open position and hydraulically release the valve to automatically return to a normally neutral position in response to a predetermined pressure in the system.
How do you adjust a hydraulic solenoid valve?
To adjust the spool valve, loosen the valve-locking nut on the side. Removing the locking nut gives you access to the adjustment screw. Turn the screw clockwise to raise the pressure, and twist it counter-clockwise to lower the pressure.
Why does my log splitter bogs down under pressure?
If your splitter is bogging down under pressure or seems weak, chances are there is something not right with how this system is operating in reference to the size of the hydraulic pump and what it is capable of.
How do you adjust a log splitter pump?
How do you tell if a hydraulic valve is open or closed center?
So in a nutshell, open-center systems always have oil flow. Closed-center systems are always under pressure but oil does not flow until you activate a lever asking the system to perform.
How to connect a log splitter?
First lower the beam into the horizontal position. It should automatically lock,but always double check.
How to fix a log splitter?
Troubleshoot – Oil Pump. Knowing precisely what is wrong with your log splitter is the first step to repair.
How to fix the automatic return on a log splitter?
this is my home made log splitter. i put a valve on the cylinder that will auto return after it is fully extended .by doing this it speeds up your cycle time .
What are the parts of a log splitter?
“A log splitter is a piece of machinery or equipment used for splitting firewood from softwood or hardwood logs that have been pre-cut into sections (rounds), usually by chainsaw or on a saw bench. Most log splitter parts consist of a hydraulic or electrical rod and piston assembly and rated by the tons of force they can generate. The higher the pressure rating, the greater the thickness or length of the rounds are split.”
