Description

Foundry goods water pressure resistance testing table
Technical field
The utility model relates to a kind of foundry goods water pressure resistance testing table.
Background technology
In the production of casting factory, by checking the seepage situation of shell class mo(u)lded piece under certain pressure to judge the quality of this foundry goods, usually by water pressure resistance that foundry goods is advanced, tested in the past.When water pressure resistance is tested, conventionally just gland bonnet is fixed on casing, without any safety precautions in the situation that, to topped up with water in casing, then the moving pressue device of armrest loads suitable hydraulic pressure; Because the intensity of some shell class foundry goods is uneven, and the controllability of manual pressure is poor, tend to cause when shell class foundry goods water pressure generation is tested, housing cracking or gland bonnet are ejected outside housing by larger pressure, cause the economic loss that testing crew is injured and larger.
Summary of the invention
Problem to be solved in the utility model is to provide a kind of water pressure resistance testing table.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of water pressure resistance testing table, comprises testing table casing, water supply mechanism and at least one sealing mechanism;
This testing table casing has a base plate, with bottom edge four side plates connected vertically and be connected in the top board of side plate.
Described sealing mechanism comprises gland bonnet, electric pushrod, gland bonnet is arranged on the opening part of foundry goods housing to be detected, described electric pushrod is fixed on testing table casing, and its push rod end stretches into testing table box house press seal lid, and sealing covers and also establishes a water inlet;
Described water supply mechanism comprises that water tank, feed pipe, high-pressure hydraulic pump, tensimeter, described feed pipe one end are communicated with water inlet, and the other end is communicated with water tank, and described high-pressure hydraulic pump, tensimeter are separately positioned on feed pipe.
As further improvement of the utility model, on described gland bonnet, be also provided with voltage stabilizing mouth, described voltage stabilizing mouth connects a surplus valve by pipeline, and this surplus valve can regulate foundry goods internal pressure to be detected.
As further improvement of the utility model, described water inlet also connects a drainpipe, which is provided with draining valve, this drainpipe is communicated with water tank, and the setting of drainpipe, after making to detect, water in foundry goods flow into water tank, not only easy to operate, and using water wisely.
As further improvement of the utility model, the junction of described gland bonnet and foundry goods box opening to be detected is provided with O-ring seal.
Advantage and the good effect that the utlity model has are: a kind of water pressure resistance testing table is provided, and this testing table possesses following advantage:
(1) adopt electronic clamping, install, convenient disassembly is quick;
(2) this testing table is provided with casing, and the accident that can effectively avoid gland bonnet to be ejected hurting sb.'s feelings occurs, and has improved the safety of operation;
(3) adopted surplus valve controlled pressure, good reliability, pressure can fine adjustment:
(4) adopt high-pressure hydraulic pump to supply water, the pressure of test current is steady, and work efficiency is high.
Accompanying drawing explanation
Fig. 1 is the structural representation of embodiment 1.
In figure: 1, testing table casing 2, electric pushrod 3, surplus valve 41, the first gland bonnet
42, the second gland bonnet 5, water tank 6, draining valve 7, tensimeter
8, high-pressure hydraulic pump 9, water inlet 10, foundry goods housing 11, voltage stabilizing mouth
12, feed pipe 13 drainpipes
Embodiment
As shown in Figure 1, the present embodiment relates to a foundry goods housing with three openings, therefore comprises testing table casing 1, water supply mechanism and three sealing mechanisms;
This testing table casing comprises a base plate, with bottom edge four side plates connected vertically and be connected in the top board of side plate.
Described sealing mechanism comprises gland bonnet, electric pushrod 2, gland bonnet is manufactured according to foundry goods shell nozzle shape to be detected, it is arranged on the opening part of foundry goods housing 10 to be detected, its junction is provided with O-ring seal, on the first gland bonnet 41 of the first sealing mechanism, also establish a water inlet 9, second sealing mechanism the second gland bonnet 42 is provided with voltage stabilizing mouth 11, and this voltage stabilizing mouth connects a surplus valve 3; Described electric pushrod 2 is fixed on testing table casing 1, and its push rod end stretches into the inner also press seal of testing table casing 1 lid;
Described water supply mechanism comprises water tank 5, feed pipe 12, high-pressure hydraulic pump 8, tensimeter 7, drainpipe 13, described feed pipe 12 one end are communicated with water inlet 9, the other end is communicated with water tank 5, high-pressure hydraulic pump 8, tensimeter 7 are separately positioned on feed pipe, water inlet platoon water pipe 13, drainpipe is communicated with water tank, and drainpipe is provided with draining valve 6.
Using method:
Three gland bonnets are fixed on the opening part of casing, make whole casing form a confined space.Foundry goods housing to be detected is fixed in the casing of testing table (as figure position), control the push rod end top tight sealing lid of electric pushrod 2, close draining valve, open high-pressure hydraulic pump, water flows into casing along pipeline, surplus valve is first discharged the air in casing, treats that surplus valve has water to overflow, and regulation relief valve raises die-casting, by tensimeter, indicate current foundry goods enclosure interior pressure to be measured, reach after predetermined pressure, keep one end time, during this, observe whether seepage of each surface of foundry goods housing to be measured.Observe completely, close high-pressure hydraulic pump, regulation relief valve, reduces pressure gradually, opens draining valve the water in foundry goods housing to be measured is emitted, and controls electric pushrod, takes out foundry goods housing to be measured, pulls down gland bonnet.
Above embodiment of the present utility model is had been described in detail, but described content is only preferred embodiment of the present utility model, can not be considered to for limiting practical range of the present invention.All equalization variations of doing according to the utility model scope and improvement etc., within all should still belonging to this patent covering scope.
