Hydraulic system for 10m sand washer

Abstract

The invention discloses a hydraulic system for a 10m sand washer. The hydraulic system comprises an oil tank, a motor, a valve group, an air cooler and an oil return filter. An air filter, a pressure gauge, a temperature sensor and a liquid level switch are installed on the oil tank. The motor is installed on the oil tank. An oil pump is installed at the front end of the motor. The power of the motor is larger than or equal to 45KW. The revolving speed of the motor is larger than or equal to 1450r / min. An oil suction filter is installed on the oil pump. The rated flow of the oil pump is larger than or equal to 105L / min. A one-way valve is installed on one side of the valve group. The oil pump is connected with the one-way valve through a connecting pipe. One side of the air cooler is connected with the valve group through a connecting pipe. The other side of the air cooler is connected with the oil return filter through a connecting pipe. By using the motor with power which is larger than or equal to 45KW to drive the oil pump, 30MPa pressure at most can be provided for the system, the hydraulic system is enabled to be capable of driving the 10m sand washer, the overload of the motor can be effectively prevented and the service life of the main machine is prolonged.

Description

【Technical field】 [0001] The invention relates to the technical field of mechanical equipment for sand washing machines, in particular to the technical field of hydraulic equipment for sand washing machines. 【Background technique】 [0002] In the past few years, the development of our industrial products has reached sublimation, and the development of the sand washing machine industry has also continued to heat up. The rise of artificial sand production has made sand washing machines quickly popular, and they have 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 sand and gravel aggregates is imminent. The impurities in the sand affect the quality of the sand, so a sand washing machine is needed to wash it. [0003] Sand washing machine is a washing equipment for artifici...

Problems solved by technology

However, the current sand washing machine uses a motor to drive the gearbox to drive the wheel of the sand washing machine, which is mechanically driven. The motor in this sand washing machine is easily overloaded, causing the motor to burn out and shortening the service life of the main machine. Therefore, it is necessary to use The hydraulic drive system is used to replace the traditional motor system. However, most of the hydraulic drive systems on the market can only drive sand washing machines about 6 meters long, and cannot drive larger sand washing machines. Sand washing machines are more efficient in cleaning sand and gravel. Low, unable to meet the large demand for sand and gravel in the market
