Abstract

The invention belongs to the technical field of hydraulic test equipment, and particularly relates to a circulating hydraulic oil source system. The circulating hydraulic oil source system involves a main oil tank, a circulating heating module and a cooling module, wherein the circulating heating module and the cooling module are connected with the main oil tank; and the circulating heating module is connected with a to-be-tested product through an oil supply valve module, and the to-be-tested product is connected with the cooling module through an oil return valve module. According to the circulating hydraulic oil source system, the circulating heating module and the cooling module which are independent of the main oil tank are arranged, all hydraulic oil in the main oil tank does not need to be heated, the hydraulic oil before entering the to-be-tested product is heated, the hydraulic oil flowing back from the to-be-tested product is cooled respectively, and heating treatment and cooling treatment are divided, so that the heating or cooling speed is effectively increased, the requirement for frequent change of the temperature of the hydraulic oil is met, and the temperature control cost is saved.

Description

technical field

[0001] The invention belongs to the technical field of hydraulic testing equipment, in particular to a circulating hydraulic oil source system. Background technique

[0002] Hydraulic oil source is an important part of hydraulic transmission and servo control device. It consists of hydraulic oil tank, hydraulic pump, motor, control valve and pipeline. The pressure, oil temperature and pollution degree of the hydraulic device are controlled. In the prior art, in the process of hydraulic product testing, the hydraulic oil often needs to be stabilized at a certain temperature, and the temperature of the oil source in the experimental site is mainly controlled by centrally controlling the oil source in the oil tank. However, due to the large volume of the oil tank and the large amount of oil for temperature control, the heating and cooling speed is slow, and the cost of temperature control is wasted, so it is difficult to meet the needs of frequent changes in hy...
