Description

一种液压发电机A hydraulic generator 技术领域Technical field
本发明涉及液压回油技术领域，具体涉及利用***回油压力实现发电的装置。The invention relates to the technical field of hydraulic oil return, in particular to a device that utilizes system oil return pressure to realize power generation.
背景技术Background technique
液压***是一种以油液作为工作介质，利用油液的压力能并通过控制阀门等附件操纵液压执行机构工作的整套装置，一般包括动力元件、执行元件、控制元件、辅助元件和液压油，动力元件如液压泵：用于把机械能转化为液压能的装置，执行元件如液压缸和液压马达：把液压能转化为机械能的装置，控制元件如液压阀：用于控制液压油压力、流动方向和液流速度的控制元件，辅助元件如油缸、滤油器、油管及管接头、密封圈、压力表、油位油温计等，液压油是液压***中传递能量的工作介质，有各种矿物油、乳化液和合成型液压油等几大类。The hydraulic system is a complete set of devices that uses oil as the working medium, uses the pressure energy of the oil and controls the hydraulic actuator to work through control valves and other accessories. It generally includes power components, actuators, control components, auxiliary components and hydraulic oil. Power components such as hydraulic pumps: devices used to convert mechanical energy into hydraulic energy, executive components such as hydraulic cylinders and hydraulic motors: devices that convert hydraulic energy into mechanical energy, control components such as hydraulic valves: used to control hydraulic oil pressure and flow direction The hydraulic oil is the working medium that transfers energy in the hydraulic system. There are various auxiliary components such as oil cylinders, oil filters, oil pipes and pipe joints, sealing rings, pressure gauges, oil level oil temperature gauges, etc. There are several categories such as mineral oil, emulsion and synthetic hydraulic oil.
液压缸式液压***，如液压升降机，其液压油在工作过程中包括进油和回油两个过程，进油过程是丛工作油缸充满油液推出活塞对外做功的过程，由液压泵提供液压能量，回油过程是油缸活塞退回时，液压油从工作油缸回流到液压***油箱，油缸活塞的退回通常由重力或***中其它储能装置提供能量，如气压缸或带有弹簧的活塞缸。由于某些领域设备对液压***的工作油缸回程工况有速度等方面的要求，因此在液压回路上通常设置有调速装置来进行控制，如节流阀；具有这类液压***的设备，在工作时，回程初期所具有的能量绝大部 分都在回程中被在液压***中的回流节流阀所消耗。对于通过采用节流阀控制回程工况的液压***，液压油在通过节流口时会产生大量热量，并在液压循环过程中不断积累，这也是造成油温升高的主要原因。而油温升高又会影响液压***的工作性能，实际上，多数液压***中为了控制液压油的温度，避免***的液压油温升过高升，通常需在液压***中增设冷却装置，这样的液压***不仅能耗大，而且排出热量大。Hydraulic cylinder type hydraulic system, such as hydraulic elevator, its hydraulic oil includes two processes of oil inlet and oil return during the working process. The oil inlet process is the process in which the working cylinder is filled with oil and pushes out the piston to perform external work. The hydraulic pump provides hydraulic energy. The oil return process is when the cylinder piston is retracted, the hydraulic oil returns from the working cylinder to the hydraulic system tank. The retraction of the cylinder piston is usually provided by gravity or other energy storage devices in the system, such as a pneumatic cylinder or a piston cylinder with a spring. Since some equipment in the field has speed requirements for the return conditions of the working cylinder of the hydraulic system, the hydraulic circuit is usually equipped with a speed regulating device for control, such as a throttle valve; equipment with this type of hydraulic system, When working, most of the energy in the initial stage of the return stroke is consumed by the return throttle valve in the hydraulic system during the return stroke. For hydraulic systems that use throttle valves to control return conditions, hydraulic oil will generate a lot of heat when it passes through the throttle, and it will continue to accumulate during the hydraulic cycle, which is also the main reason for the increase in oil temperature. The increase in oil temperature will affect the working performance of the hydraulic system. In fact, in most hydraulic systems, in order to control the temperature of the hydraulic oil and avoid excessive rise in the temperature of the hydraulic oil in the system, it is usually necessary to add a cooling device to the hydraulic system. The hydraulic system not only consumes a lot of energy, but also emits a lot of heat.
针对上述情况，本创造研究旨在充分利用能量，对液压***能量进行回收，简化液压***，实现液压***的节能减排。In view of the above situation, the purpose of this creative research is to make full use of energy, recover the energy of the hydraulic system, simplify the hydraulic system, and realize the energy saving and emission reduction of the hydraulic system.
