Description
Technical field
The invention belongs to the pressure vessel test technical field, relate to a kind of pressure vessel hydraulic fatigue test equipment.
Background technology
For the pressure vessel that bears alternate load, for guaranteeing its performance, need carry out torture test to pressure vessel, i.e. pressure in accordance with regulations, container is pressurizeed and release repeatedly, until this pressurization repeatedly with till the release number of times reaches some, with this, one of criterion of using as pressure vessel safety.Pressure vessel was carried out the test unit that torture test is adopted in the past, the general test unit of building by the experiment process that GB/T9252 recommended that adopts, but fatigue experimental device according to this flow scheme design, exist solenoid valve and Hydraulic Elements wearing and tearing and premature damage easily, and in release not control during, produce very big impact and noise with commutation from the high-pressure fluid of internal tank.Though, adopt the ratio electromagnetic relief valve to improve hydraulic flow, can control release speed, control is complicated, and the easy wear problems of solenoid valve still exists simultaneously.Why produce above-mentioned deficiency, trace it to its cause, relevant with the hydraulic means that existing test unit is adopted, therefore, it is very necessary to design a kind of novel pressure container fatigue test device.
Summary of the invention
The purpose of this invention is to provide the interior impurity of a kind of prevention container enters in the hydraulic valve, reduce the wearing and tearing of hydraulic valve, improve the serviceable life of hydraulic valve, the release speed of control container inner high voltage medium, reduce release impact and noise, control hydraulic fatigue test system for pressure container easily
Technical solution of the present invention is, a kind of pressure vessel hydraulic fatigue test device, pressurize by oil circuit, pressurize, pressure relief device and Measurement and Control System are formed, the oil circuit pressurization, pressurize, pressure relief device comprises by pipeline connection, motor-driven oil pump 1, solenoid valve 2, surplus valve 3, water-cooled oil cooling machine 6, oil-returning filtering device 7, fuel tank 8 and the pipeline that is connected thereof, Measurement and Control System is by being used for pressure vessel, hydraulic fluid temperature is measured the electro connecting pressure gauge 9 with control, temperature sensor 10, pressure transducer 11, computing machine 12, controller 13 is formed, it is characterized in that: solenoid valve 2 with tried pipeline that container links to each other on be provided with one-way throttle valve 4 and high pressure filtering device 5, on the return line 16 that solenoid valve 2 links to each other with fuel tank, surge tank 17 is housed.
Solenoid valve 2 is an O type function.
Solenoid valve 2 is a M type function.
Solenoid valve 2 is a U type function.
Solenoid valve 2 is a J type function.
The invention has the beneficial effects as follows, be applicable to that pressure vessel inside contains the torture test that impurity needs to carry out elevated pressures again, also be applicable to the transformation of existing pressure container fatigue test device.It has, cost is low, be easy to characteristics such as realization.

Embodiment
A kind of pressure container fatigue test system, its formation comprises: with oil circuit pressurization, pressurize, the pressure relief device be made up of motor-driven oil pump 1, solenoid valve 2, electromagnetic relief valve 3, one-way throttle valve 4, high pressure filtering device 5, water-cooled oil cooling machine 6, oil-returning filtering device 7 and fuel tank 8 of pipeline connection and be used for pressure vessel and hydraulic fluid temperature is measured the Measurement and Control System of being formed with electro connecting pressure gauge 9, temperature sensor 10, pressure transducer 11, computing machine 12, the controller 13 of control.
From pressure transducer 11, electro connecting pressure gauge 12, the signal of temperature sensor 10 all links to each other with computing machine by lead, when give as required computing machine 12 input data necessary with for information about after, requirement according to computing machine 12, controller 13 is in the oil pump 1 that starter motor drives, the P mouth that can make solenoid valve 2 be communicated with the A mouth that is tried the pipeline 15 that container links to each other, the pressure signal that is tried container is sent to by pressure transducer 11 and carries out computing in the computing machine 12, when the pressure display pointer that reaches the upper limit pressure set in the computing machine 12 or electro connecting pressure gauge 9 when the force value that transmits by pressure transducer 11 contacts with upper limit pressure qualification pointer, computing machine 12 sends action command by controller 13 automatically to solenoid valve 2, each mouthful of solenoid valve 2 is in off-state, tried container and be in packing state, when pressurize begins, instruction from computing machine 12 opens electromagnetic relief valve 3 by controller 13, from the hydraulic oil of oil pump 1 by water-cooled oil cooling machine 6, oil-returning filtering device 7 enters fuel tank 8; When pressurize reaches official hour, computing machine 12 sends action command by controller 13 to the other end of solenoid valve 2, the A mouth of solenoid valve is communicated with the T mouth, the pressure medium that is tried in the container returns fuel tank 8 by high pressure filtering device 5, one-way throttle valve 4, solenoid valve 2, surge tank 17, water-cooled oil cooling machine 6, oil-returning filtering device 7 and each section associated line successively, regulate one-way throttle valve 4, can regulate release speed, high pressure filtering device 5 isolation are tried, and impurity enters in the hydraulic valve in the container; Reduced in the computing machine 12 display pointer of the threshold pression set or electro connecting pressure gauge 9 when contacting when trying container inner pressure with threshold pression qualification pointer, computing machine 12 sends action command by controller 13 automatically to solenoid valve 2, each mouthful of solenoid valve 2 is in off-state, tried container pressurize under threshold pression.In step-down and lower limit pressure maintaining period, electromagnetic relief valve 3 is in opening all the time.When the lower limit that reaches regulation after the dwell time, computing machine 12 is pressed said process once more, accepts and send instruction, by boosting-running order of pressurize-step-down-pressurize, carries out repeatedly, reaches being tried the purpose that container carries out torture test.Adopt electromagnetic relief valve 3 can pass through computing machine 12, accurate and regulated at will is tried the upper and lower limit pressure of container.
