Abstract

The invention discloses a hydraulic system for a sand washer. The hydraulic system comprises an oil tank, a first motor, a second motor, a first oil pump, a second oil pump, a first filter, a first valve group, a water cooler, a second filter, a second valve group and a third motor, wherein an air filter, a temperature sensor, the first filter and a floating ball liquid-level meter are arranged on the oil tank; an electromagnetic overflow valve, a pressure stabilization valve, a blockage alarm device and a pressure adjustment valve are arranged on the first valve group. According to the hydraulic system, the oil pumps are driven by the motors; hydraulic oil enters a hydraulic motor through a valve block to drive a roll crusher to rotate, so that overload of the motor can be effectively prevented, and the service life of a main unit is prolonged; the filters can keep the hydraulic oil clean and not polluted; the water cooler can cool the hydraulic oil; the stability of the work of the hydraulic system is improved, and the service lives of parts are prolonged; a liquid level switch can sound a high-liquid-pressure alarm and a low-liquid-pressure alarm to prevent the liquid level of the oil liquid from being too high or too low.

Description

【Technical field】 [0001] The invention relates to the technical field of mechanical equipment for double-roll machines, in particular to the technical field of hydraulic equipment for double-roll machines. 【Background technique】 [0002] Over the past few years, the development of our industrial products has reached sublimation, and the development of the double-roll machine industry has also continued to heat up. The rise of artificial crushing production has made the product popular quickly, and it has been recognized by everyone almost overnight. Now the demand for this equipment in the market continues to increase, which shows its popularity. At present, the development of the construction industry continues to heat up, and the demand for high-quality and fine sand and gravel aggregates is also imminent. Some ores with medium hardness and The rock can only be processed and used after being crushed by a double-roller machine, so it needs to be crushed by a double-roller m...
