What is the mechanical component of the pressure relay in the hydraulic system?

Answer:

Mechanical components: common parts or components such as gears and rack. Hydraulic system is made up of dynamic components (pump), executive components (cylinder or hydraulic motor), control components (valves), auxiliary components and working medium of five parts.
Hydraulic components are tubing, tank, hydraulic pump, hydraulic cylinder, inlet valve and outlet valve
Working principle pressure relay is the hydraulic electrical conversion element which USES the pressure of the liquid to turn off the electric contact. When the system pressure reaches the pressure relay setting value, the electrical signal, make electrical components (such as electromagnet. Motor. Time relay, electromagnetic clutch, etc.), make the oil pressure relief. Reversing, executing the sequence of elements, or turning off the motor to stop the system from working and protecting the system. Pressure relays have plunger type. Diaphragm. Spring tube type and corrugated pipe type four forms of structure. When the relay is lower inlet into the liquid pressure reaches the set pressure value, the fortress, promote column after the displacement by leveraging promoting micro switch. Changing the compression of the spring can adjust the pressure of the relay. Note: pressure relays must be placed in areas where pressure has significant changes to output electrical signals. If the pressure relay is put on the oil circuit, the pressure will not change due to the direct return of the oil to the fuel tank, so the pressure relay will not work.
