Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic control systems, in particular to a ceramic high-pressure grouting and film pressing hydraulic system. Background Art

[0003] The existing laminating machine uses a single oil pump to control the hydraulic system. The pressing and separation speeds of the hydraulic system are too slow. When laminating the ceramic substrate, the pressing speed is slow. During large-scale production, the production efficiency is not enough to meet the existing production needs. If the speed is forced to be increased, the hydraulic system will become unstable.

[0004] Therefore, a ceramic high-pressure grouting film pressing hydraulic system is needed to increase the pressing speed and maintain the stability of the hydraulic system. Utility Model Content

The stacked pressure-maintaining valve is connected to the pressing and separation solenoid valve. The stacked pressure-maintaining valve is used to protect system components. When the system pressure is too high, the pressure-maintaining valve will automatically open to reduce the system pressure and prevent the system components from being damaged; when the system pressure is too low, the pressure-maintaining valve will automatically close to prevent the system components from failing to work normally due to too low pressure. The pressing and separation solenoid valve is used to control the pressing and separation of the oil cylinder.

[0010] Preferably, an overflow valve is provided in the system. The overflow valve is a hydraulic pressure control valve, which mainly plays the role of constant pressure overflow, pressure stabilization, system unloading and safety protection in hydraulic equipment.

[0011] Preferably, a pressure relay is provided in the system, and the pressure relay is connected to the first motor oil pump group and the second motor oil pump group respectively. The pressure relay is a component in the hydraulic system that causes the electric contact to operate when the fluid pressure reaches a predetermined value. The pressure relay can also be defined as a hydraulic component that converts pressure into an electrical signal. The customer can adjust the pressure relay according to their own pressure design needs to achieve the function of outputting an electrical signal at a certain set pressure.
