From the structural analysis of hydraulic power unit, it can be divided into two parts: signal control and hydraulic power.The signal control part is mainly used to drive the action of the control valve in the hydraulic power part.The hydraulic power part mainly includes hydraulic pump, motor and hydraulic auxiliary parts.
So, do you know how the hydraulic power unit works in practice?In fact, it works primarily through a combination of other external devices and various internal devices.Generally speaking, it is mainly composed of three parts, forming a system, namely power oil source system.For mechanical equipment, it has many advantages.
In fact, in a hydraulic system, the power unit is a very important part, because it directly determines the operation of the entire system.Moreover, the hydraulic power unit can control any valve switch in the system, and the system switch can be realized quickly.Of course, in daily use, if a system failure is found, it needs to be solved in time to prevent the problem from worsening.
It should be noted that when starting up the hydraulic power unit, it is a good idea to first try a few times, then make sure everything is ok, and then run underground for five to ten minutes.Then it is ready for normal operation.In addition, it is important to note that the cleanliness of the entire system, especially the hydraulic fluid, should not be contaminated prior to operation and therefore should provide a cleaner working environment.
The power unit is mainly used to supply power to the actuator, which is mainly a hydraulic pump. The liquid output by certain control and regulating devices (various hydraulic valves) can be used to perform certain actions of the actuator, such as the hydraulic cylinder.Telescopic or hydraulic motor rotation!
Hydraulic pipeline installation is a major project of hydraulic system equipment installation.The quality of pipeline installation is one of the keys to the normal performance of hydraulic system.
1.Piping design and piping shall be considered as an integral consideration of components, hydraulic components, fittings and flanges connected according to the hydraulic schematic.
2.The pipes used must have clear raw materials. Pipes of unknown materials are not allowed to be used.Performance description of hydraulic power unit
3.Hydraulic systems can cut pipe diameters of 50mm or less.Generally, tubes with diameters of 50mm or larger should be machined.If gas cutting is used, mechanical means must be used to drive part of the tissue formed by gas cutting, and at the same time, to drive out the weld groove.Except for return lines, roll extrusion cutters do not allow cutting pressure.The cut surface of the pipe must be flat to remove burrs, scales, slag, etc.The cutting surface shall be perpendicular to the axis of the tube.
4.Tubes less than 30 mm in diameter can be cold bent.Cold or hot bending can be used when the outer diameter of the tube is 30 to 50mm.When the outer diameter of the tube is greater than 50mm, the thermal bending method is usually used.
5.When hydraulic pipe butt welding, the weld wall must be 0.3~0.5mm higher than the pipe.Indentation in the inner wall is not allowed.After welding, use a shovel or hand-held grinding wheel to flatten the weld on the inner wall.Remove slag and burr to achieve smooth finish.
6.During the whole welding process, wind, rain and snow should be prevented.After welding the pipe, the welding seam with the wall thickness of 5mm or less should be cooled naturally at room temperature. Strong wind or water should not be used for forced cooling.
Select according to the ambient temperature used.In the machine with high ambient temperature or near heat source, oil or flame retardant oil with high viscosity temperature should be preferred.In order to ensure the safety and reliability of hydraulic system under harsh working conditions, oil with good viscosity and temperature characteristics, thermal stability, lubricity and corrosion resistance must be selected.
The power unit is optimized for a variety of applications, such as trucks in harsh environments, heavy-duty operations in long-term use, and other applications that require high performance and quality.This has resulted in an extremely versatile platform that USES standard components to handle most application conditions required by the market, minimizes customer hydraulic component inventory, and significantly reduces the workload of non-standard designs..
