篮球比分Hydraulic transmission has many advantages and occupies an important position in the development of electromechanical integration in our country. However, in hydraulic transmission, energy loss (leakage loss, overflow power loss, throttle power loss, friction loss, etc.) is large, and transmission efficiency is low. These energy loss of hydraulic system will become heat, making the system temperature rise, and high temperature will affect the service life of hydraulic components and system reliability, so in the design of hydraulic transmission must consider to improve efficiency. This paper mainly discusses this problem from three aspects.

1. Reasonable selection of power components

篮球比分This mainly refers to the selection of hydraulic pump and motor, which should be matched according to the working load diagram, especially the quantitative pump model should not be too large, so as to reduce energy consumption.

2. Reasonably arrange pipelines

In the layout of the pipeline, as far as possible to shorten the length of the pipeline, reduce the pipeline bending and section of the sudden change, the inner wall of the pipe to smooth, choose a reasonable pipe diameter, use a lower flow rate, can reduce the pressure loss of the system, improve the efficiency of the system.

篮球比分3. Reasonable selection of hydraulic circuit

篮球比分Proper circuit selection can obviously improve efficiency and reduce energy consumption.

1) when the parallel oil supply circuit of double pumps is fast, the two pumps supply oil at the same time. When the operation is fed, the high pressure and small flow pumps supply oil, so as to realize the reasonable use of energy.

2) the accumulator is matched with the small flow pump in the loop of the accumulator to meet the large flow demand of the hydraulic system. When the hydraulic cylinder stops moving, the pump will fill the accumulator with oil; When the hydraulic cylinder works, the pump and accumulator supply oil simultaneously.

篮球比分3) volume speed regulation circuit volume speed regulation circuit does not throttle power loss and overflow power loss of throttle speed regulation circuit, with high efficiency.

篮球比分4) unloading circuit According to the formula N=P Q, such as the output flow of the pump Q. Is zero, or the output pressure P is zero, can make the output power of the pump N is zero and achieve unloading. When each actuator in the system does not work temporarily, if the hydraulic pump is still discharged back to the oil tank with the pressure value set by the overflow valve, it will cause power loss and oil heating, so the no-load operation of the pump can save energy, some hydraulic pumps with large power should be started under light load in order to protect the motor.

5) the open pressure of the remote control balance valve in the remote control balance circuit has nothing to do with the back pressure of the hydraulic cylinder, generally only 30% ~ 40% of the system pressure. The piston downward balance valve is opened by the control oil, the back pressure disappears, and the system efficiency is higher.
