specific Embodiment approach 1
[0013] Specific implementation mode one: combine figure 1 Describe this embodiment. This embodiment consists of a hydraulic oil tank 1, an oil suction filter 2, a hydraulic oil pump executive assembly 3, a servo driver 4, a touch screen 6, an alarm light 7, a PLC controller 8, an analog input and output module 9, and a 24V Composition of DC power supply 10;
[0014] Hydraulic oil pump executive assembly 3 includes base 3-1, servo motor 3-2, Oldham coupling 3-3, pressure sensor 3-4, oil pump 3-5, accumulator 3-6, temperature sensor 3- 7. The safety valve 3-8; the servo motor 3-2 and the oil pump 3-5 are installed on the base 3-1, and the servo motor 3-2 is connected to the oil pump 3-5 through the Oldham coupling 3-3. Pressure sensor 3-4, accumulator 3-6, temperature sensor 3-7 and safety valve 3-8 are all installed on the output pipeline of oil pump 3-5; the input port of oil pump 3-5 is connected with the output of oil suction filter 2 The port is connected, and the oil suc...
specific Embodiment approach 2
[0017] Specific implementation mode two: combination figure 1 Describe this embodiment, the difference between this embodiment and Embodiment 1 is that the touch screen 6 is provided with flow mode and pressure mode options; when the flow mode is selected, the PLC controller 8 automatically follows the formula Calculate the speed n of the servo motor 3-2, and let the servo motor 3-2 run at a constant speed n. At this time, the product of the displacement and the speed of the oil pump 3-5 is the output flow; at the same time, the PLC controller 8 outputs the oil circuit according to the oil pump 3-5. The pressure change of the oil pump 3-5 judges whether the output oil passage of the oil pump 3-5 is leaked or blocked; when selecting the pressure mode, first input the pressure setting value, and then the PLC controller 8 is based on the pressure signal data collected by the pressure sensor 3-4, and the output pressure and The relationship between the servo motor 3-2 speed: , ...
specific Embodiment approach 3
[0019] Specific implementation mode three: combination figure 2 To illustrate this embodiment, this specific embodiment adds a box body 11 on the basis of the specific embodiment one; the box body 11 is divided into three layers: upper, middle and lower;
[0020] The alarm lamp 7 and the touch screen 6 are all arranged on the upper panel of the box body 11; the servo driver 4, the PLC controller 8, the analog input and output module 9 and the 24V DC power supply 10 are all arranged in the upper layer of the box body 11; 3 is arranged in the middle layer of the box body 11; the hydraulic oil tank 1 and the oil suction filter 2 are both arranged in the lower layer of the box body 11. Other compositions and connections are the same as in the first embodiment.
[0021] This implementation mode is an integrated design, simple and beautiful, and very convenient to operate;
[0022] working principle:
[0023] Before operating the system, first judge the working condition of the ...
