Description
Technical field
The utility model is related to a kind of load charger of pressure test, more particularly to suitable for PR2 grades of performances of well head
The load charger of slips casing hanger load test in experiment.
Background technology
In API 6A standards, PR2 performance tests require to carry out load cycle experiment for slips hanger, and in actual oil
In gas production operation, slips casing hanger suspension sleeve weight, which often weighs tens tons, arrives tons up to a hundred, and well head PR2 experiments will use up
Amount, which meets, will carry out the CYCLIC LOADING of load in actual condition, and process of the test, need to tear open repeatedly during CYCLIC LOADING
Weight is filled, working strength is big, and less efficient, potential safety hazard is larger, therefore, be difficult to have found a mass both in process of the test
Meet corresponding weight demands, restrictive condition of the experimental enviroment space to mass size can be met again.
The content of the invention
In order to solve the above problems, the utility model provides a kind of load charger of pressure test, and the device is expired
Technical requirements needed for foot experiment.
In order to achieve the above object, the utility model is achieved through the following technical solutions：
The utility model is a kind of load charger of pressure test, including hydraulic pressure cylinder assembly, on hydraulic pressure cylinder assembly
Reserve two oil pump interfaces, the external imposed load oil pump of an interface, one external to shed load oil pump, piston rod and hydraulic cylinder
Component piston is connected through a screw thread, and is sealed by filler, locking nut and hydraulic pressure cylinder assembly, and piston rod leads to stretch rod
Cross adapter sleeve to be attached with latch, stretch rod is sealed with adpting flange by filler, locking nut, adpting flange and liquid
Connected between cylinder pressure component by shoring, shoring is hydraulic cylinder imposed load and stretches piston rod, stretch rod rear support
Adpting flange, adpting flange is sealed with four-way junction of casing by Stud connection, and by gasket ring, sleeve pipe frock and stretching
Bar is connected through a screw thread, and slips casing hanger is located in four-way junction of casing, jackscrew is tightened after being installed in place, with stationary slip
Casing hanger, pressure testing flange is located on four-way junction of casing, tightens periphery stud.
Further improvement of the utility model is：The load mode of slips casing hanger load is to be added by hydraulic cylinder
Pressure is loaded.
Further improvement of the utility model is：Shoring is two-flap type shoring.
The beneficial effects of the utility model are：The present apparatus can simulate slips casing hanger suspension sleeve in actual production
Weight, by being pressurizeed to hydraulic cylinder to produce active force corresponding with casing wt, is realized to slips casing hanger
Load is loaded, and can meet the test requirements document for carrying out the loading of load cycle test procedure load in well head PR2 experiments to hanger, and
Experiment security, operating efficiency are improved, technical requirements needed for experiment are met.
