Problems solved by technology
The pressure gauge elbow is an accessory used to connect the pressure gauge and the equipment or pipes measured by the pressure gauge. It is used to buffer the instantaneous impact of the measured medium on the spring tube of the pressure gauge, and at the same time reduce the temperature of the measured medium. The accumulator can only bypass part of the flow pulse in the pipeline, and cannot effectively prevent the propagation of the oil pressure pulsation in the pipeline caused by the change of the working load; the existing pressure gauge bend and accumulator The structure of the energy device cannot effectively solve the problems of hydraulic pulsation and temperature rise when hydraulic motors are used in agricultural cutting machinery

The invention relates to a heat-dissipating pipeline of an energy storage hydraulic motor self-adaptive to load change. The heat-dissipating pipeline comprises an oil inlet pipe connected to an oil inlet of the hydraulic motor. The oil inlet pipe, of a spiral pipe structure, is suitable for converting reverse impact kinetic energy generated by sudden increase of a load of the hydraulic motor intocompression potential energy of liquid oil in the spiral pipe and elastic deformation potential energy of the spiral structure of the pipeline and storing the compression potential energy and the elastic deformation potential energy in the position of the oil inlet pipe. The elastic deformation potential energy of the oil inlet pipe is released or accumulated in real time along with fluctuation ofthe load of the hydraulic motor for supplementing impact action of the hydraulic motor to the load. The heat-dissipating pipeline provided by the invention has the beneficial effects that the spiralpipe structure of the oil inlet pipe can convert the impact kinetic energy of pressure pulsation generated in a hydraulic pipeline into the potential energy of the spiral pipe and storing residual energy in pressure pulsation in the liquid oil of the oil inlet pipe and the elastic deformation of the spiral pipe, and the oil inlet pipe can stretch along with pressure pulsation to balance the pressure pulsation, so that the condition that the pulsation is propagated along the pipeline is reduced.
Description
technical field [0001] The invention relates to a heat dissipation pipeline of an energy storage hydraulic motor adaptive to load changes. Background technique [0002] At present, hydraulic motors are often used in agricultural cutting machinery to drive high-speed rotating knives to cut crops. However, due to uneven distribution of crops and differences in strength and toughness of crops, the load on the knives during cutting varies greatly; The hydraulic motor generally adopts the gear motor structure, and the hydraulic pipeline itself has pressure pulsation, coupled with the load change on the tool, the main wave and harmonic components of the pressure fluctuation inside the gear motor are more complicated, so that the gear motor The floating seal works unstable, leading to increased oil leakage inside the motor; on the other hand, the pressure fluctuations caused by load changes will propagate along the pipeline to other hydraulic piping systems or hydraulic components,...
