About This

• Uses: The hydraulic machine model is used in the middle school physical demonstration experiment to explain the structure and working principle of the hydraulic machine.
• Structure: This instrument is divided into two types: pressure gauge and pressure gauge. They are composed of three parts and accessories such as large and small cylinders and pressure gauges or angle cut-off valves and bases. The large and small cylinders are fixed on the bottom plate and connected by a conduit. The bottom plate is fixed to the base with the fuel tank.
• Cylinder: The size of the cylinder consists of the upper seat, the cylinder liner (made of plexiglass), the base and the oil-resistant rubber gasket. Each cylinder is tensioned by three tie rods. There is a piston in the cylinder. A handle can be mounted on the upper end of the piston in the small cylinder. The piston portion of the large cylinder expands into a working platform.
• Globe valve and pressure gauge: The angle-type globe valve consists of an intermediate body and a valve and a safety valve and a discharge pipe whose normal pressure has been adjusted to 1.8 ± 0.2 MPa.
• The hydraulic machine with gauge is a pressure gauge seat at this location: it consists of a watch base, a connecting pipe, a valve stem, a pressure gauge and a liquid outlet pipe. Base: mainly composed of fuel tank, oil suction valve, oil pressure valve and conduit
