Description

An energy-saving spring-type hydraulic power machine

technical field

The invention relates to the technical field of power machines, in particular to an energy-saving spring-type hydraulic power machine.

Background technique

Hydraulic power machine is a type of hydraulic engine. Hydraulic engine refers to an engine that uses liquid as a working medium and uses the pressure energy of liquid to transmit power.

An engine is a machine that can convert other forms of energy into mechanical energy, including internal combustion engines (gasoline engines, etc.), external combustion engines (Stirling engines, steam engines, etc.), electric motors, and the like. For example, internal combustion engines usually convert chemical energy into mechanical energy. The engine applies to both the power generating device and the entire machine including the power device (eg gasoline engine, aero engine). The engine was first born in the United Kingdom, so the concept of the engine is also derived from English, and its original meaning refers to the kind of "mechanical device that generates power".

A complete hydraulic system consists of five parts, namely energy device, execution device, control and adjustment device, auxiliary device, and liquid medium. Hydraulics are widely used in industrial and civil industries due to their large transmission power, easy transmission and configuration. The function of the actuators (hydraulic cylinders and hydraulic motors) of the hydraulic system is to convert the pressure energy of the liquid into mechanical energy, so as to obtain the required linear reciprocating motion or rotary motion. The function of the energy device (hydraulic pump) of the hydraulic system is to convert the mechanical energy of the prime mover into the pressure energy of the liquid.

When the traditional hydraulic power machine is stopped, the internal hydraulic oil will not stop flowing immediately, resulting in a long stoppage process, and external braking is required. However, the external braking has certain safety hazards. If mistakes are made in the operation process, it is easy to cause safety accidents.

In addition, some hydraulic power machines are equipped with electronically controlled braking devices. Since the devices require power supply, an additional power supply mechanism needs to be installed, which leads to the need for power machines to consume more energy and increases production costs.
