The system can realize the oil supply by multiple pumps with different models and specifications in a hydraulic system and meet operation requirement.
Description
Technical field
The utility model relates to a kind of wagon drill hydraulic oil interflow system that is, the many valves of the many pumps of particularly big flow interflow system.
Background technique
In the prior art, flow surpasses on the 300L/min market product seldom in high-capacity pump and the large-capacity valve, and technology is not overripened yet.At the super-flow (more than the 2000L/min) of realizing hydraulic system is a difficult point technically.Producer's technology customized is immature and cost is very high.
Summary of the invention
The purpose of this utility model is to overcome above deficiency, a kind of many valves of the many pumps of big flow interflow system that is used for wagon drill is provided, under present high-capacity pump, the jejune situation of valve, satisfy the requirement of big flow in the wagon drill hydraulic system, improved the working efficiency of wagon drill.
The purpose of this utility model realizes by following measure, the many valves of the many pumps of a kind of big flow interflow system, its actuator 3 connects hydraulic control multi-way valve 1, hydraulic control multi-way valve 2, hydraulic control multi-way valve 4 and manual multiple-way valve 5 by pipeline respectively, and manual multiple-way valve 5 connects metering pump 6; Load feedback type hydraulic control multi-way valve 1 link variable pump 7, hydraulic control multi-way valve 2, hydraulic control multi-way valve 4 link variable pumps 8, variable displacement pump 9 and variable displacement pump 10, each hydraulic control multi-way valve and variable displacement pump all join with fuel tank.
The flow specification of above-mentioned hydraulic control multi-way valve is 90-220L/min, and variable pump delivery specification is 60-105cm
3/ rev.Realized that same actuator can change the quantity of oil feed pump easily, and oil pump can be a plurality of models and different size.
Above-mentioned actuator 3 is big cylinder diameter oil cylinder, and the oil cylinder cylinder diameter is 180mm.
The structure of above-mentioned manual multiple-way valve 5 is a 3-position 4-way multichannel hand-operated direction valve.
The utility model working principle is: various dissimilar pumps such as variable displacement pump 6, variable displacement pump 7, variable displacement pump 8, variable displacement pump 9, variable displacement pump 10 collaborate to carry out work to control executing mechanism 3 by dissimilar multidisc multiple directional control valves such as hydraulic control multi-way valve 1, hydraulic control multi-way valve 2, hydraulic control multi-way valve 4 and manual multiple-way valves 5.Variable displacement pump adopts the load feedback mode, and when induced pressure was lower than 24MPa, metering pump can collaborate with variable displacement pump easily, and when induced pressure was higher than 24MPa, because the pressure limit of metering pump own, this moment, metering pump can not be worked.
In sum, adopt the many valve combinations of conventional many pumps to replace high-capacity pump, valve, satisfied the big traffic requirement of hydraulic system, reduced the manufacture cost of equipment, improved the reliability of hydraulic system.
