Abstract

The invention discloses a hydraulic testing system which comprises a first hydraulic pump and a first motor, wherein the hydraulic pump is driven by the first motor; an oil suction opening of the first hydraulic pump is communicated with an oil tank; an adjustable safety valve, a high-pressure filter and a pressure meter are arranged at an oil outlet of the first hydraulic pump. The hydraulic testing system also comprises an oil return pipe, wherein an oil intermingling pipe is connected in series between an outlet of the high-pressure filter and the return oil pipe; a stop valve is also arranged on the return oil pipe. According to the hydraulic testing system, a high-displacement oil intermingling pump and a low-displacement pressure pump are arranged, so that the good oil intermingling effect is achieved, and energy is saved during pressurizing.

Description

Hydraulic test system
Technical field
The present invention relates to a kind of hydraulic test system, particularly a kind of for pipeline string oil and the hydraulic test system suppressed, belong to hydraulics field.
Background technique
The turbidity test of hydraulic system are particularly important to hydraulic system, no matter be that loader or other mechanical hydraulic systems all need pipeline to clean before assembling, conventionally the method adopting is string oil, also need in addition to hydraulic pipe line and hydraulic system suppress test detect hydraulic pipe line and system whether exist reveal with and bearing capacity, the complicated string oil of current hydraulic test system mechanism needs different systems with suppressing, and the test of hydraulic system bothers very much.
Summary of the invention
The object of this invention is to provide a kind of hydraulic test system, particularly a kind of for pipeline string oil and the hydraulic test system suppressed.
Technological scheme: a kind of hydraulic test system, comprise the first oil hydraulic pump and the first motor, described the first oil hydraulic pump is driven by described the first motor, the inlet port of described the first oil hydraulic pump is communicated with fuel tank, the oil outlet of described the first oil hydraulic pump is provided with adjustable safety valve, and high pressure filter and pressure gauge also comprise return tube, the outlet that string oil pipe string is connected on described high pressure filter also, between described return tube, is also provided with stop valve on described return tube.
Preferably, on described return tube, be also provided with return filter.
Preferably, also comprise the second motor of the second oil hydraulic pump and described the second oil hydraulic pump of driving, the inlet port of described the second oil hydraulic pump is communicated with described fuel tank, and its oil outlet is communicated with the oil outlet of described the first oil hydraulic pump, and described the first hydraulic pressure pump delivery is greater than described the second hydraulic pressure pump delivery.
Working principle: between high pressure filter described in needs string oil and the hydraulic tube connecting band suppressed and described return tube, when string oil, regulate described safety valve to suitable pressure, open described stop valve, start described the first motor, described the first motor drives described the first oil hydraulic pump, thereby goes here and there oil.
While suppressing, start described the second motor, described the second motor drives described the second oil hydraulic pump, closes described stop valve, heightens gradually the setting value of described safety valve, until required pressure, sees whether hydraulic pipe line occurs the phenomenons such as leakage of oil at then pressurize a period of time.
Because described the first hydraulic pressure pump delivery is greater than described the second hydraulic pressure pump delivery, the first oil hydraulic pump fuel feeding described in when oil string, the oily effect of the large string of flow is better, uses the more happy festival time energy of the second oil hydraulic pump of small displacement while suppressing.
The present invention makes to go here and there oily better effects if by the string oil pump of large discharge capacity and the pressuring pump of small displacement are set, happy festival time energy more while suppressing.
Brief description of the drawings
Fig. 1 is embodiment of the present invention schematic diagram.
Embodiment
Below in conjunction with drawings and Examples, the invention will be further described:
Embodiment one:
As shown in Figure 1, a kind of hydraulic test system, comprise the first oil hydraulic pump 1 and the first motor 2, described the first oil hydraulic pump 1 is driven by described the first motor 2, and the inlet port of described the first oil hydraulic pump 1 is communicated with fuel tank 3, and the oil outlet of described the first oil hydraulic pump 1 is provided with adjustable safety valve 4, high pressure filter 5 and pressure gauge 6, also comprise return tube 7, the outlet that string oil pipe 8 is serially connected in described high pressure filter 5 also, between described return tube 7, is also provided with stop valve 12 on described return tube 7.
On described return tube 7, be also provided with return filter 9.
Also comprise the second motor 11 of the second oil hydraulic pump 10 and described the second oil hydraulic pump 10 of driving, the inlet port of described the second oil hydraulic pump 10 is communicated with described fuel tank 3, its oil outlet is communicated with the oil outlet of described the first oil hydraulic pump 1, and the discharge capacity of described the first oil hydraulic pump 1 is greater than the discharge capacity of described the second oil hydraulic pump 10.
Working principle: between high pressure filter 5 described in needs string oil and the pipe connecting band suppressed and described return tube 7, when string oil, regulate described safety valve 4 to suitable pressure, open described stop valve 12, start described the first motor 2, described the first motor 2 drives described the first oil hydraulic pump 1, thereby goes here and there oil.
While suppressing, start described the second motor 11, described the second motor 11 drives described the second oil hydraulic pump 10, close described stop valve 12, heighten gradually the setting value of described safety valve 4, until required pressure, then pressurize a period of time, check whether string oil pipe occurs the phenomenons such as leakage of oil.
In addition to the implementation, the present invention can also have other mode of executions, and all employings are equal to the technological scheme of replacement or equivalent transformation formation, all drop in the protection domain of requirement of the present invention.
