Background technology
The primary cut-out hydraulic mechanism is very high to the cleannes requirement of hydraulic system, and impurity content can not surpass 0.08 gram/platform in every circuit breaker hydraulic system of national Specification.At present domestic have only 90% can reach this standard, average content 0.071 gram/platform.Impurity can cause the product leakage of oil, frequently suppress even influence the stability and the reliability of product in the circuit breaker hydraulic system.How removing the impurity in the hydraulic system, is the key technology that improves hydraulic mechanism, and domestic manufacturer mainly by improving the machining accuracy of parts, strengthens and improve the cleannes that parts deburring means are controlled hydraulic system now.This means are difficult to the Control of Impurities of hydraulic system is arrived the demand of primary cut-out to hydraulic mechanism.
The utility model content
The purpose of this utility model provides the external constant voltage flusher of a kind of hydraulic mechanism, can thoroughly remove or reduce the intrasystem impurity of primary cut-out hydraulic mechanism.
The technical solution of the utility model is: the external constant voltage flusher of a kind of hydraulic mechanism, this device comprises motor, supply reservoir, oil extraction fuel tank and is loaded on the high-pressure oil pump of motor output end, supply reservoir is provided with and is used for the oil inlet pipe that is communicated with the hydraulic mechanism oil draining system, supply reservoir is communicated with the oil extraction fuel tank by filter, the oil extraction fuel tank is communicated with the oil-in of high-pressure oil pump by oil exit pipe, the oil-out of high-pressure oil pump is communicated with by the normal high-pressure system of fuel feed pump and hydraulic mechanism, is provided with Pressure gauge on fuel feed pump; Oil exit pipe is provided with pressure switch apparatus, also is provided with travel switch in this pressure switch apparatus.
On described supply reservoir, oil level indicator is housed.
Described motor is an alternating current machine.
This device also comprises casing, and motor and high-pressure oil pump are arranged at the bottom in the casing, and supply reservoir and oil extraction fuel tank are arranged at the middle and upper part in the casing, and two fuel tanks form at interval by a longitudinal baffle, and described filter installment is on dividing plate.
The utility model designs at the existing present situation that can not totally thoroughly remove impurity in the primary cut-out hydraulic mechanism system.This flusher can provide various flushing pressures according to the difference of using hydraulic mechanism.This device design has enough big fuel tank, for the each action of primary cut-out hydraulic mechanism provides the hydraulic oil of clean cleaning that hydraulic system is washed, and hydraulic mechanism is moved the hydraulic oil that has impurity of the discharging oil inlet pipe by supply reservoir at every turn be recovered to this device, use by filtration cycle, thereby thoroughly remove the intrasystem impurity of primary cut-out hydraulic mechanism.After using the flushing of this device, impurity content can both reach the national standard of 0.08 gram/platform, average content 0.033 gram/platform in the circuit breaker hydraulic system.Pressure switch apparatus by control motor startup and stop to be controlled to be the size that hydraulic mechanism provides hydraulic fluid pressure, thereby provide different force value according to the hydraulic mechanism of different model.Pressure gauge monitors the pressure of flusher, is convenient to direct read-out system force value.
