Technical field
The utility model relates to a kind of anti-explosion product pressure test device, particularly a kind of anti-explosion product water test unit.
Background technology
Used hydraulic testing equipment before the explosion-proof electrification engineering department is the homemade old-fashioned simple machine of a cover, and its principle of work (step) is:
First with a water pump separately to test shell (being tested body) water filling, fill with water after, housing is carried out closed processes;
2. suppress to housing by force (forcing) pump, treat that pressure is raised to regulation and requires (ordinary test requires pressure 1MPa), in 10 seconds of termination of pumping pressurize, then release of pressure discharges water.
This overlaps testing equipment, has complicated operation in the process of using, and the force (forcing) pump flow is little, pressing time long (needing tens minutes such as the combined switch housing), the problems such as pressurize is unstable, release of pressure time length.
Wherein, pressurization, long, the pressurize of release of pressure time are unstable to be to need the problems that solve emphatically.Because according to requirement of experiment, reach in the 1MPa situation at pressure, pressurize got final product in 10 seconds.If pressurization, release of pressure overlong time can increase the distortion of explosion-proof casing to a certain extent, if be out of shape excessive, can directly affect core body assemble and the later stage working strength of housing; If pressurize is unstable, just be not easy to find the problems such as weld seam trachoma that explosion-resistant enclosure exists in welding process, pore.
Summary of the invention
The purpose of this utility model is to improve the defective of prior art, and a kind of anti-explosion product water test unit is provided.This device has solved well in the hydraulic testing and has pressurizeed, the release of pressure time is long, the problems such as pressurize is unstable make the pressurized time shorten of test shell (being tested body) within 30 seconds, have greatly reduced the stress deformation time of explosion-proof casing, satisfy requirement of experiment, improved work efficiency.
For achieving the above object, the utility model provides a kind of anti-explosion product water test unit, and described device comprises tested body, water pump, inlet pipeline and outlet pipeline; Described tested body is provided with tensimeter A, and this tensimeter A links to each other with described tested body by operation valve A; One end of described inlet pipeline is connected with the water inlet of described tested body by operation valve B, and the other end is connected with the water delivering orifice of described water pump by adjusting reduction valve;
Also be provided with tensimeter B on this inlet pipeline, described tensimeter B is connected with inlet pipeline by operation valve C;
Described outlet pipeline is connected with the water delivering orifice of described tested body by operation valve D.
Further, described water pump is lift greater than 110 meters centrifugal pump.
Further, link together by rapid-acting coupling between an end of described inlet pipeline and the operation valve B; Link together by rapid-acting coupling between the other end of described inlet pipeline and the described adjustment reduction valve.
Further, link together by rapid-acting coupling between described outlet pipeline and the operation valve D.
Further, the water inlet place of described water pump is provided with operation valve E.
Principle of work of the present utility model is: at first select lift greater than 110 meters centrifugal pump, at the water delivering orifice of water pump the adjustment reduction valve is installed, adjusting the reduction valve top hole pressure is that testing requirements pressure 1MPa(is that tensimeter B is shown as 1MPa), guaranteed the highest experimental pressure of tested body.Open all operation valves (A-E) during work, open water pump toward the interior water filling of tested body, after the outlet pipeline water outlet, adjust the flow of operation valve D, attention can not close fully that (according to characteristics curve of centrifugal pump, when flow was zero, discharge pressure was zero, exit of pump pressure was maximum when flow was very little), tensimeter A indicating value begins timing when reaching 1MPa, switches off the pump during 10 second, and release discharges water.At this moment because water pump is out of service, the water in the tested body can get final product rapid pressure release by two pipelines of inlet and outlet pipe in 2～3 seconds.
The utility model is compared with existing product, has following actively useful effect:
1, with water-filling and pressure pump unification, pressurization in the hydraulic testing, long problem of release of pressure time have been solved.
2, water inlet and the water outlet at test shell (being tested body) increases operation valve, can be by two rapid pressure releases of pipeline of inlet and outlet pipe.
3, by this technological transformation, test specimen pressurized, pressurization have been solved well in the hydraulic testing and the problem such as the release of pressure time is long, pressurize is unstable, greatly reduce the stress deformation time of explosion-proof casing (being tested body), satisfied requirement of experiment, improved work efficiency.
