Oil temperature control system of hydraulic oil tank

Abstract

The invention relates to an oil temperature control system of a hydraulic oil tank. The oil temperature control system of the hydraulic oil tank comprises the hydraulic oil tank provided with a hydraulic oil pump; an oil outlet pipeline of the hydraulic oil pump is provided with an overflow valve; an electric heater is further arranged in the hydraulic oil tank; the oil outlet pipeline is provided with a heat exchanger; an oil inlet A of the heat exchanger communicates with an oil outlet of the hydraulic oil pump; an oil outlet B of the heat exchanger communicates with the hydraulic oil tank; in addition, a water tank is further arranged and internally provided with an electric water pump; a water outlet of the electric water pump communicates with a water inlet C of the heat exchanger through a pipeline; and a water outlet D of the heat exchanger communicates with the water tank. The oil temperature control system of the hydraulic oil tank heats hydraulic oil through the electric heater, and the problem that the temperature of the hydraulic oil is too low is solved; the heat exchanger and the water pump are adopted, and the oil temperature of the hydraulic oil tank is fast and accurately controlled; and while the test condition is guaranteed, time is saved and work efficiency is improved. The hydraulic oil pump and an oil return filter are adopted for performing forced filtration on the hydraulic oil of the hydraulic oil tank, pollution of a hydraulic system is avoided, the service life of the system is prolonged, and cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of hydraulic test, and in particular relates to an oil temperature control system of a hydraulic oil tank of a hydraulic test stand. Background technique [0002] Keeping the oil temperature of the hydraulic oil in a reasonable range is of great significance to the accuracy of the test results of the hydraulic test bench. At present, the hydraulic oil tank equipped on the hydraulic test bench generally does not have a temperature control system. In order to meet the temperature conditions of the test, the method of throttling or overflow is used to increase the temperature of the hydraulic oil at the beginning of the test, which wastes energy and time. When the system temperature exceeds When the temperature is high, the hydraulic oil is cooled by stopping and waiting, which is a waste of time and low work efficiency. Contents of the invention [0003] In order to realize rapid and accurate control of the...

At present, the hydraulic oil tank equipped on the hydraulic test bench generally does not have a temperature control system. In order to meet the temperature conditions of the test, the method of throttling or overflow is used to increase the temperature of the hydraulic oil at the beginning of the test, which wastes energy and time. When the system temperature exceeds When the temperature is high, use the method of stopping and waiting to cool down the hydraulic oil, which is a waste of time and low work efficiency
