Description
Technical field
The utility model relates to hydraulic oil source technical fields, and in particular to a kind of testing machine oil sources.
Background technique
Testing machine generally uses hydraulic servo control system, and hydraulic oil source is major impetus source, by oil pump to fuel tank
Extending and retracting for the discharge control piston rod of interior hydraulic oil, realizes the up and down of crossbeam and stepping up, unclamping for jaw,
Thus clamping, release and stretching, the test such as flexible of metal or nonmetallic materials sample are completed.The execution of different testing machines
Flow needed for element and pressure difference, output flow, which can according to need, carrys out regulated variable hydraulic pump, when output flow is turned down
When, hydraulic oil demand also accordingly becomes smaller, but the oil mass in fuel tank will not tail off as output flow is turned down, now hydraulic
The tankage of oil sources is all bigger, be easy to cause the waste of hydraulic oil in this way, not economic and environment-friendly enough, such as when regulated variable pumps
It is cumbersome to replace fuel tank.
Utility model content
In order to solve the above technical problems, the oil mass in fuel tank can root the utility model proposes a kind of testing machine oil sources
Change according to the size of variable pump output flow, avoids wasting.
Using following technical scheme:
It is passed including motor, the first oil pump, the second oil pump, the first fuel tank, the second fuel tank, controller, flow sensor, liquid level
Sensor and valve, the motor connect with the first oil pump shaft, and the first oil pump is connect with the first fuel tank, and first oil pump connects flow
Sensor, first fuel tank is interior to connect liquid level sensor, and first fuel tank lower part has valve, and the valve passes through oil pipe
The second fuel tank is connected, second fuel tank also passes through the second oil pump and connects the first fuel tank, the motor, the first oil pump, the second oil
Pump, flow sensor, liquid level sensor and valve are connect with controller.
Second fuel tank is placed in the lower section of the first fuel tank, and the valve connects the top of the second fuel tank by oil pipe.
First oil pump is volume adjustable hydraulic pump.
The flow sensor is ultrasonic flow sensor.
First fuel tank connects the first oil pump by oil filter.
It further include bracket, the motor, the first oil pump, the second oil pump, the first fuel tank and the second fuel tank are mounted on bracket
On.
It further include shell, the outer casing inner wall covers soundproof plate.
The utility model has the beneficial effects that
This testing machine oil sources is arranged by two fuel tanks of setting, in oil pump out of the mouth setting flow sensor, in fuel tank
Liquid level sensor, controller etc. make the oil mass in fuel tank that can be become properly, to be also provided with according to the variation of oil pump output flow
Shell with soundproof plate avoids waste and environmental protection.
Detailed description of the invention
The component connection schematic diagram of Fig. 1 the utility model, arrow direction are the direction of running of hydraulic power oil.
The electrical connection schematic diagram of Fig. 2 the utility model.
Specific embodiment
The embodiments of the present invention is specifically illustrated with reference to the accompanying drawing, and attached drawing is only for reference and illustrates use, not structure
The limitation of pairs of the utility model patent protection scope.
As shown in Figure 1, a kind of testing machine oil sources, including motor, the first oil pump, the second oil pump, the first fuel tank, the second oil
Case, controller, flow sensor, liquid level sensor and valve, motor connect with the first oil pump shaft, the oil absorbing end of the first oil pump and
The connection of one fuel tank, the oil outlet of the first oil pump connect flow sensor, connection liquid level sensor in the first fuel tank, under the first fuel tank
Portion have valve, valve by oil pipe connect the second fuel tank, the second fuel tank also pass through the second oil pump connection the first fuel tank, motor,
First oil pump, the second oil pump, flow sensor, liquid level sensor and valve are connect with controller.
Second fuel tank can be placed in the lower section of the first fuel tank, and volume is smaller than the first fuel tank, and valve passes through oil pipe connection second
The top of fuel tank facilitates oil from the first fuel tank and flows to the second fuel tank.Volume adjustable hydraulic pump, flow sensor can be used in first oil pump
Ultrasonic flow sensor can be used, the first fuel tank connects the first oil pump by oil filter, and high-pressure filter can be used in oil filter.
Unidirectional quantitative hydraulic pump can be used in second oil pump.
This testing machine oil sources may also include bracket, and motor, the first oil pump, the second oil pump, the first fuel tank and the second fuel tank are equal
It is installed on bracket.
This testing machine oil sources may also include shell, inside the shell wall cover soundproof plate, motor, the first oil pump, the second oil pump,
The components such as the first fuel tank, the second fuel tank and valve are placed in shell, and noise is generated when preventing oil sources from working.
The course of work:
According to need of work, after adjusting motor and volume adjustable hydraulic pump, when variable delivery hydraulic pump output flow being made to become smaller, flow is passed
When sensor detects that flow is less than the flow threshold of setting, the valve that controller controls the first fuel tank is opened, and flows to hydraulic oil
Second fuel tank, when liquid level sensor detects the oil level of the hydraulic oil of the first fuel tank less than the bottom level limit set, control
The valve that device controls the first fuel tank is closed, the hydraulic oil that at this moment storage temporarily takes less than in the second fuel tank, motor and variable delivery hydraulic
Pump works under less and suitable fuel tank fuel quantity.
According to need of work, after adjusting motor and volume adjustable hydraulic pump, when variable delivery hydraulic pump output flow being made to become larger, flow is passed
When sensor detects that flow is greater than the flow threshold of setting, controller controls the work of the second pump start, from the second fuel tank to the
Oil transportation in one fuel tank, when liquid level sensor detects that the oil level of the hydraulic oil of the first fuel tank is greater than the liquid level upper limit value of setting, control
Device processed controls the second oil pump and stops working, after at this moment the oily almost all in the second fuel tank is extracted into the first fuel tank, motor and change
Amount hydraulic pump works under more and suitable fuel tank fuel quantity.
Above description is merely a prefered embodiment of the utility model, is not intended to limit the utility model, for
For those skilled in the art, various modifications and changes may be made to the present invention.All spirit and original in the utility model
Within then, any modification, equivalent replacement, improvement and so on be should be included within the scope of protection of this utility model.
