Ultimate high quality stainless steel hydraulic sensor

Product description

The variable system of hydraulic excavator mainly adopts the combination of variable pump and quantitative motor to realize the stepless speed change, and both of them are double pumps and double circuits. Depending on whether the variables of the two circuits are related, they can be divided into two kinds: sub-power variable system and total power variable system. Each oil pump in the power variable system has a power regulating mechanism. The flow of oil pump is only affected by the pressure change of its own loop, and has nothing to do with the pressure change of other loops. That is, the two circuits of the oil pump independent constant power adjustment variables, two oil pumps each have a barrel of engine output power; The two oil pumps in the total power variable system are balanced by the total power regulating mechanism, so that the pendulum Angle of the two oil pumps is always the same, and the synchronization variable and flow rate are equal. The total pressure of the system determines the flow rate variation. The power of the two oil pumps is different in the range of variables. Its regulating mechanism has mechanical connecting rod type and hydraulic connecting rod type two forms. The hydraulic pressure sensor detects the changes of the excavator hydraulic system in real time and feeds back to the control system. The control system adjusts the displacement of hydraulic pump and motor according to the change of data, so as to realize variable control, so as to improve the working efficiency of excavator, reduce energy consumption, reduce operation intensity and so on. Specializing in the production of hydraulic high Pressure Transmitter, Water Pressure Sensor, water pump pressure transmitter, CNG/LPG High Pressure Sensor, intake manifold absolute pressure sensor, water purifier pressure transmitter.
