S 32 X by Schwing - Concrete Pump

Even when the concrete pump is not engaged, this separate hydraulic circuit continues to operate for protection and performance. Redesigned for 800 LPM of oil, the 3 High Flow Control Block is the brain for the all hydraulic system. The block incorporates the Soft Switch into the relief valve and the accumulator manifold into the S3 spool valve

How does a REED Concrete Pump work?

The main pump circuit is equipped with a manifold that is drilled and ported to accommodate the relief valve, check valve, flow control and the pilot operated directional valve. The cycle valve is a directional spool valve with electro hydraulic solenoid operation.


of the system at a pre-determined level. Relief valve protects the hydraulic pump and in turn the prime mover from overload quickly in case the system is exposed to overpressure. That's why, characteristics of such a valve like the other system components are very important in designing the hydraulic system. The basic pressure relief valve is

HPS10 Hydraulic Spray Pump - China Concrete Mixer Pumps

2. Large valve changing direction, makes the main pumping loop quick response, small leakage, good stability,high reliability and high resist contaminative capability. 3. Hydraulic system has safe relief protection,at the same time,when the system pressure is over, the main oil pump cutting device makes itself be protected reliably. 4.

Assemble a Hydraulic Pilot-operated Pressure Relief Valve

Oct 10, 2019 · Relief valves are used to limit maximum pressure in hydraulic systems. When system pressure begins to exceed the pressure setting of the relief valve, a controlled amount of hydraulic fluid by-passes through the relief valve to the tank port and limits the system pressure to the valve setting. The two basic types of relief valves […]

The main system relief valve is set too high. C. The hand pump outlet check valve is sticking open. What happens to the output of a constant-displacement hydraulic pump when the hydraulic system pressure regulator diverts the fluid from the system to the reservoir? The out put pressure reduces, but the volume remains the same.

Most Common Causes of Hydraulic Systems Failure | YorkPMH

Feb 13, 2020 · We can trace most hydraulic issues back to a few common causes, listed below. 1. Air and Water Contamination. Air and water contamination are the leading causes of hydraulic failure, accounting for 80 to 90% of hydraulic failures. Faulty pumps, system breaches or temperature issues often cause both types of contamination.

Pump Compensator Adjustment Procedure

H. Start the system. (Full pump flow will be flowing across the relief valve at this point.) I. Slowly increase the setting of the safety relief valve to approximately 250-300 psi above the desired system operating pressure…as indicated on the pressure gauge. (There will likely be a high pitched squeal or noise from the relief valve. This is
