Abstract

The invention discloses a six-mode double-oil-way oil supply system. The system comprises a six-position five-way electro-hydraulic proportional valve, wherein the six-position five-way electro-hydraulic proportional valve is provided with a first oil inlet, a second oil inlet, an oil return port, a first oil outlet and a second oil outlet; the first oil inlet is connected with a first hydraulic pump oil source through a first oil way; the second oil inlet is connected with a second hydraulic pump oil source through a second oil way; the first hydraulic pump oil source and the second hydraulic pump oil source are both connected with an oil tank; the first oil inlet is connected with a pilot overflow valve or a direct-acting overflow valve; and the second oil inlet is connected with a pilot overflow valve or a direct-acting overflow valve. The six-mode double-oil-way oil supply system is reasonable in whole layout, compact in structure, convenient for control, flexible in control, low in power loss, high in system efficiency and high in economic benefit.

Description

technical field [0001] The invention relates to the field of hydraulic technology, in particular to a six-mode dual oil circuit oil supply system. Background technique [0002] In the past, when the large-scale mechanical equipment in the market was working, the work efficiency was greatly reduced due to insufficient oil supply, and the oil supply system could not provide a suitable oil supply circuit according to the working conditions of the actuators, which seriously affected the working performance of the machine. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a six-mode dual oil circuit oil supply system with strong versatility, reasonable overall layout, compact structure, convenient operation, flexible control, low power loss and high economic benefits. The six-mode dual oil circuit oil supply system provided by the present invention can form different oil supply circuits by changing the logical position ...
