System to reduce line loss in pressure control hydraulic circuit
A hydraulic system including a first cylinder conduit configured to couple to a cylinder, a second cylinder conduit configured to fluidly coupled to the cylinder, and a bypass conduit fluidly coupled both to the first cylinder conduit upstream of the cylinder and to the second cylinder conduit downstream of the cylinder. The bypass conduit is configured to enable intermittent fluid flow of a hydraulic fluid from the first cylinder conduit to the second cylinder conduit while bypassing at least a portion of the cylinder.
1. A hydraulic system comprising:
a first cylinder conduit configured to fluidly couple to a cylinder;
a second cylinder conduit configured to fluidly coupled to the cylinder; and
a bypass conduit fluidly coupled both to the first cylinder conduit at a first end of the cylinder and to the second cylinder conduit at a second end of the cylinder opposite the first end, wherein the bypass conduit is configured to enable intermittent fluid flow of a hydraulic fluid from the first cylinder conduit to the second cylinder conduit while bypassing at least a portion of the cylinder, wherein the cylinder comprises a rephasing cylinder having a piston, wherein the rephasing cylinder comprises the bypass conduit, and the bypass conduit is configured to enable the intermittent fluid flow of the hydraulic fluid from the first cylinder conduit to the second cylinder conduit while bypassing the piston of the rephasing cylinder.
2. The hydraulic system of claim 1 , wherein the first cylinder conduit, the bypass conduit, and the second cylinder conduit form a portion of a circulation conduit that enables circulating flow of the hydraulic fluid along the circulation conduit that causes the hydraulic fluid to be at a viscosity that minimizes hydraulic losses along the circulation conduit.
3. A hydraulic system, comprising:
a first cylinder conduit;
a second cylinder conduit;
a cylinder fluidly coupled to the first cylinder conduit and the second cylinder conduit;
a bypass conduit fluidly coupled both to the first cylinder conduit at a first end of the cylinder and to the second cylinder conduit at a second end of the cylinder opposite the first end, wherein the bypass conduit is configured to enable intermittent fluid flow of a hydraulic fluid from the first cylinder conduit to the second cylinder conduit while bypassing the cylinder, and wherein the first cylinder conduit, the bypass conduit, and the second cylinder conduit form a circulation conduit configured to enable circulating flow of the hydraulic fluid along the circulation conduit;
a valve disposed along the bypass conduit, wherein the valve is configured to enable intermittent fluid flow of the hydraulic fluid from the first cylinder conduit to the second cylinder conduit while bypassing the cylinder;
a plurality of temperature sensors disposed along the first cylinder conduit, the second cylinder conduit, and the bypass conduit; and
a temperature monitoring system configured to monitor a temperature of the hydraulic fluid based on feedback from the plurality of temperature sensors and to cause blocking of the intermittent flow of the hydraulic fluid from the first cylinder conduit to the second cylinder conduit along the bypass conduit when the temperature reaches a threshold temperature by closing the valve.
4. A hydraulic system for an agricultural implement having a ground engaging tool, comprising:
a first cylinder conduit;
a second cylinder conduit;
a cylinder fluidly coupled to the first cylinder conduit and the second cylinder conduit;
a bypass conduit fluidly coupled both to the first cylinder conduit at a first end of the cylinder and to the second cylinder conduit at a second end of the cylinder opposite the first end; and
a bleed orifice disposed along the bypass conduit, wherein the bleed orifice is configured to enable intermittent fluid flow of a hydraulic fluid from the first cylinder conduit to the second cylinder conduit while bypassing the cylinder while the ground engaging tool is being actuated by the hydraulic system.
5. The hydraulic system of claim 4 , comprising a check valve disposed along the bypass conduit, wherein the check valve is configured to block fluid flow back to the first fluid conduit along the bypass conduit.
6. The hydraulic system of claim 5 , wherein the check valve is disposed upstream of the bleed orifice along the bypass conduit.
7. The hydraulic system of claim 5 , comprising a screen filter disposed along the bypass conduit, wherein the screen filter is disposed upstream of the check valve and is configured to keep contaminants from entering the check valve and blocking fluid flow through the check valve.
8. The hydraulic system of claim 4 , wherein the first cylinder conduit, the bypass conduit, and the second cylinder conduit form a circulation conduit configured to enable circulating flow of the hydraulic fluid along the circulation conduit.
