Abstract
Provided is a manual hydraulic type universal tester which is used to test strength performances of various materials and mainly improves the shortcomings of a complex structure, a large volume and a high cost existing in prior hydraulic testers. The utility model modifies the electric hydraulic system of the electric hydraulic type universal tester in prior art to the manual hydraulic oil pump and then is composed by a frame, a piston cylinder, a reversing valve and a pressure display instrument. Therefore, the utility model has both test functions of tension and compression and conducts strength test to the undemountable parts in the 'abdominal' of the device as well as the parts inner side thereof. The utility model has the advantages of no electric power consumption, a simple structure, convenient carrying and a low cost.
Description
The utility model relates to a kind of universal hydraulic testing machine that is used for the test material strength character.
Prior art generally adopts the electric hydraulic testing machine to stretching, compression, shearing, crooked equicohesive detection of material, as: YJS series pressure testing machine, the WE Series Hydraulic formula universal testing machine that LJ series tension tester and tension and compression are had both.All be to constitute by framework, motor, motor speed regulation system, hydraulic oil pump, valve body group, fuel reserve tank, piston cylinder, pressure display instrument table.Obviously, its volume, weight are all very big, can only be provided in the laboratory.To detecting such as production process, the used scene of production teams and groups, power free countryside is detected and all can not be used, and particularly the inside of some equipment, member is carried out the detection of " intraperitoneal ", and is powerless especially.And these testing machine prices are also higher, are generally 3~60,000 yuan/platform.
The purpose of this utility model provides a kind of without electric power, and volume is small and exquisite, is easy to carry, hand-hydraulic formula universal testing machine with low cost.
The purpose of this utility model reaches by following measures: a kind of hand-hydraulic formula universal testing machine is to be made of framework, piston cylinder, reversal valve, pressure display instrument table, it is characterized in that: hydraulic oil pump is the manual hydraulic oil pump without electric power.The operator starts the handle of hydrodynamic pressure oil pump with hand, makes the oil pump pressure oil output go driven plunger to finish and draws, presses work, and material is carried out intensity detection.By the test speed of the test method defined of act.std, the drawing of manual hydraulic oil pump output, pressure can satisfy various detections need.Also save simultaneously the electric hydaulic part of electrodynamic type hydraulic dynamometer, realized the purpose of this utility model.
The utility model compared with prior art, and is simple in structure, and volume, weight, cost have all reduced more than 60%.
The utility model is described in further detail below in conjunction with drawings and Examples:
Fig. 1 is the structural map of vertical hand-hydraulic formula universal testing machine.
Fig. 2 is the structural map of horizontal hand-hydraulic formula universal testing machine.
Fig. 3 is the hydraulic schematic diagram that the utility model comprises the manual hydraulic oil pump structure.
Among the figure: 1. framework; 2. piston cylinder; 3. reversal valve; 4. pressure display instrument table; 5. manual hydraulic oil pump; 6. handle; 7. detected material; 8. plunger case; 9. oil sucting one-way valve; 10. press oily retaining valve; 11. accumulator.
Among Fig. 1, piston cylinder 2 is vertically placed, and can detect materials samples.Be suitable do the vertical of indoor application or weighting platform formula hand-hydraulic formula universal testing machine.
Among Fig. 2, piston cylinder 2 horizontal positioned are horizontal hand-hydraulic formula universal testing machine.But it is the sample of test material not only, and " intraperitoneal " that also can be placed on equipment, member carries out the detection of situ strength to non-dismountable part.This moment, shape, the size of framework 1 will need design by detecting.Present embodiment is the requirement of the industry standard CJ/T3002-92 " polyurethane foam plastic prefabricated direct-buried thermal insulation pipe " according to the Ministry of Construction, detects pressure on the product body, draws the special-purpose testing machine of performance.
Among Fig. 3, manual hydraulic oil pump is made of accumulator 11, plunger case 8, handle 6, oil sucting one-way valve 9, the oily retaining valve 10 of pressure.Be reduced volume, simplify oil circuit, plunger case 8 is immersed in the hydraulic oil, and volume is little and oil-proof.The hydraulic system principle: on the handle 6 of raising one's hand, oil sucting one-way valve 9 is opened, and presses oily retaining valve 10 to close, plunger case 8 is by accumulator 11 oil suctions; Handle 6 is depressed, and two retaining valves exchange worker's shape and pose, and plunger case 8 is pressed oil, through reversal valve 3 to piston cylinder 2 fuel feeding.The stretching of piston cylinder 2, the operating state of compression are by reversal valve 3 controls.
Claims (2)
1. hand-hydraulic formula universal testing machine, be in metal framework, piston cylinder, reversal valve, pressure display instrument table be by the hydraulic pressure installation that is linked in sequence, it is characterized in that: supplying with test is the hand hydraulic oil pump with the hydraulic oil pump of pressure oil.
2. hand-hydraulic formula universal testing machine according to claim 1, it is characterized in that: the plunger case of hand hydraulic oil pump and accumulator are concentric structures, and are immersed in the hydraulic oil.
