High-low-temperature oil cooling machine used in cooperation with test of traction motor

Abstract

The invention relates to a high-low-temperature oil cooling machine used in cooperation with test experiment of a traction motor. The high-low-temperature oil cooling machine can simulate the influences of high temperature and low temperature to motor starting, motor thermal expansion, motor coil resistance value, motor lubricating performance, motor durability and motor heat dissipation, so that the performance of the traction motor when operating under actual working conditions is mastered. An upper computer transmits an operation command to the oil cooling machine, then the effect that the requirements of the command can be met in the aspects of temperature, flow and pressure can be accurately guaranteed, and accordingly the working condition parameters required by the test can be better simulated, the data of the traction motor in the actual using process are obtained, and data support is provided for the improvement of the motor. A user can accurately simulate the working conditions as long as the user is familiar with the operation of the upper computer, and the convenience and comfort of user operation are also achieved.

Description

technical field [0001] The invention relates to a high and low temperature oil cooler used for traction motor test experiments, especially it can simulate high temperature and low temperature for motor start-up, motor thermal expansion and cold contraction, motor coil resistance, motor lubrication performance, and motor durability , The effect of motor heat dissipation, so as to grasp the performance of the traction motor under actual working conditions. Background technique [0002] At present, the oil coolers used in the traction motor test experiment are all normal temperature oil coolers, which cannot meet the requirements of the experiment itself for temperature changes, so that the working conditions and performance curves of the traction motor under high or low temperature conditions cannot be obtained. Defects in the current product: 1. Cannot simulate high temperature and low temperature; 2. Can only manually adjust the flow rate, and cannot output the flow rate acc...
