The above describes the pressure regulating circuit. This article will show you the specific situation of the decompression circuit, the boost circuit and the unloading circuit.
1, the pressure reduction circuit
1 Function: Make a certain part of the oil circuit in the hydraulic system have a lower stable pressure.
2 Application: control oil circuit, clamping circuit, lubricating oil circuit.
3 main hydraulic components: fixed value pressure reducing valve.
4 Operation method: Connect a pressure reducing valve in front of the oil circuit that needs decompression.
5 common circuits: one-way decompression circuit, two-stage decompression circuit.
2. Booster circuit
1 role: make the pressure of a certain part of the branch in the hydraulic system higher than the system pressure.
2 main hydraulic components: supercharger.
3 common circuits: the boost circuit of the single-acting supercharger and the boost circuit of the double-acting supercharger.
a, single-acting supercharger booster circuit
The single-acting booster circuit is generally only suitable for occasions where the hydraulic cylinder requires a large force in one direction and a short stroke. When the supercharger 1 is left-handed, its high-pressure chamber is replenished from the high-position tank through the check valve, and the cylinder 2 is returned by the internal Spring.
When the supercharger is on the right side, its high pressure chamber outputs high pressure oil, so that the cylinder 2 outputs a large force.
Relying on the supercharger can achieve higher pressures than the system pressure.
Since the area of ​​the left and right chambers of the supercharger is A1>A2, according to the principle of right and left force balance, the pressure of the right chamber is higher than that of the left chamber when extending.
The high pressure provided by the supercharger operates in a single-acting cylinder in the circuit.
b. Double-acting supercharger booster circuit
When the supercharger 2 is right, its high pressure chamber B outputs high pressure oil through the check valve 6, whereas when the solenoid valve is energized, the high pressure chamber A of the supercharger outputs high pressure oil through the check valve 5.
As long as the solenoid valve 1 is continuously switched, the double-acting supercharger 2 can continuously output high-pressure oil.
3, unloading circuit
1 Definition: The hydraulic pump operates with a small output power (close to zero). That is, the hydraulic pump operates at a very low pressure (close to zero) or outputs a low flow (close to zero) pressure oil.
The frequent start and stop of the pressure pump affects the life of the hydraulic pump, and the unloading circuit needs to be set.
3 common circuits:
a. Use the unloading circuit of the neutral function of the three-position reversing valve.
b. Use the unloading circuit of the two-position two-way valve.
