The hydraulic system reasonably designed by the hydraulic station manufacturer can effectively reduce the energy loss of the system. Generally, the following steps should be followed in the design of the hydraulic system: analysis work-select the correct components-draw the hydraulic system diagram-determine the power components, control components and auxiliary components- -Check calculations, etc.
Hydraulic system
1. Regarding the selection of china Custom Accumulator Manufacturer energy-saving circuits. For example: the unloading circuit is to make the output flow of the hydraulic oil pump flow back to the oil tank under the condition of very low pressure when the hydraulic oil pump does not stop rotating, so as to reduce the power loss, reduce the heating of the system, and prolong the life of the pump and motor; while the pressure maintaining circuit It is to make the system maintain the pressure stably when the hydraulic cylinder does not move or has only a small displacement.
2. Optimize the system organization and make a reasonable layout. On the premise of meeting the performance requirements, combined with the cycle, it is necessary to pay attention to the optimized system structure and rational layout. Simple and dependable. Avoid redundant hydraulic components and pipelines, use an integrated design as much as possible, keep the pipes as short as possible, and minimize the number of joints to reduce the loss of resistance along the way and local, so as to achieve the purpose of energy saving.
3. Regarding the selection of components, the components with high efficiency and low energy consumption should be selected as much as possible. If a variable pump with high efficiency is selected, the pressure can be changed according to the needs of the load to reduce energy consumption, and an integrated valve can be selected to reduce the number of pipe connections. Pressure loss, select a proportional valve with small pressure drop and continuous control, etc.
The quality of the hydraulic oil in the hydraulic cylinder is very important. The better hydraulic oil contains preservatives, which can increase the shelf life of the oil, but if it takes a long time, it needs to be replaced. Otherwise, the preservatives in the hydraulic oil will fail. It will damage the function of the hydraulic press. When replacing the hydraulic oil, the filter must be carefully cleaned, because the filter only filters out the stains and dirt in the oil, and cannot filter other substances contained in the oil.
The density of hydraulic oil will change with the change of temperature. The temperature increases and the density decreases, but the change is small. It is generally considered to be a constant, and the viscosity changes with the temperature. Before use, be sure to keep the hydraulic oil clean, put the oil in a sealed place, and it is impossible to expose to the sun or get wet. When adding oil to the oil tank, you must choose a suitable filter to filter . In the process of adding, be sure to ensure that all containers are clean and clean. If dirt enters the oil, you need to replace the hydraulic oil. Remember, be sure to keep all utensils clean.
In order to reduce the leakage caused by the loosening of the pipe joints subjected to shock and vibration, the following measures can be taken: use shock-absorbing brackets to fix all pipes to discharge shock and vibration; properly arrange pressure control valves to protect all components of the system; increase the number of pipe joints as much as possible. Use quantity, pipe joints should be welded as much as possible; use straight threaded joints, tee joints and elbows instead of tapered pipe threaded joints.
