Abstract
The utility model discloses a high-pressure sealing piston for a pulse test of an engine body. High-pressure oil is well sealed when high pressure is adopted in the test of the engine body so as to guarantee the stability and consistency of the test pressure. The device is similar to a piston of a real engine in shape and comprises a high-pressure oil bearing surface, a sealing ring groove of two O-shaped rings and a check ring, a guide strip groove, a connecting rod body and a crankshaft journal hole, wherein the piston is installed in a cylinder sleeve. Hydraulic pressure is applied to the high-pressure oil bearing surface and transmitted to the engine body by the crankshaft matched with the connecting rod body and the crankshaft journal hole so as to examine and evaluate the reliability and intensity of the engine body. By adopting the two sealing rings and cylinder sleeves for sealing, the leakage of the high-pressure oil on the edge of the piston caused by deformation of the cylinder sleeve can be avoided.
Description
Technical field
The utility model relates to engine components test equipment field, and particularly a kind of engine body impulse test is used the high pressure sealing piston.
Background technique
In the body hydraulic fatigue test, adopt piston, connecting rod and the bent axle (d-axis) of simulation and cylinder block, crankcase to assemble.Yet the body intensity under the high detonation pressure of simulated engine exists more difficult point and problem.Can know according to tired statistical theory; The on-load pressure of general fatigue test is 1.25-2 a times of real engine pressure of explosion, and pressure acts on piston head, through piston, connecting rod shank and simulation bent axle on-load pressure is passed to body; The general hydraulic oil that adopts withstand voltage Wear-resistant, high-temperature resistant of pressure-loaded medium; For guaranteeing to be loaded into pressure stability and the conformity on the body, therefore, guarantee that in test piston is the problem place of this test stand to the sealing of high pressure oil always.In case because high pressure oil is revealed, not only can not guarantee finally to be loaded into the pressure size on the body, also can cause corresponding danger for testing installation itself.
The model utility content
The utility model provides a kind of engine body impulse test to use the high pressure sealing piston to the oil-tightening difficult point of above engine body test mesohigh, and it is simple in structure, and is practical and convenient.
Be to realize above-mentioned purpose, the high pressure sealing piston of the utility model, the piston of the similar real engine of its shape comprises the supporting plane of high pressure oil, the closure gasket groove of 2 road O type circles and back-up ring, 1 road lead trough of belt, connecting rod shank and crankshaft journal hole.The supporting plane of high pressure oil; The closure gasket groove of O type circle and back-up ring, the guiding trough of belt, connecting rod shank and crankshaft journal hole connect successively; The supporting plane 1 of high pressure oil directly carries the hydraulic oil that is higher than motor detonation pressure 2 multiplication of voltage power, and piston rod body and journal hole and Engine Matching are installed.
This test is installed in the cylinder sleeve of engine with the high pressure sealing piston, adopts the two seals face, prevented to cause the leakage of piston edge high pressure oil because of cylinder-liner distortion.

Embodiment
Fig. 1 is this device high pressure sealing piston plan view, and the piston of the similar real engine of its shape comprises the supporting plane 1 of high pressure oil, the closure gasket groove 2 and 3 of twice O type circle and back-up ring, the trough of belt 4 that leads together, connecting rod shank 5 with and crankshaft journal hole 6.The supporting plane 1 of high pressure oil, the closure gasket groove 2 and 3 of O type circle and back-up ring, guiding trough of belt 4, connecting rod shank 5 and crankshaft journal hole 6 connect successively.The supporting plane 1 of high pressure oil directly carries the hydraulic oil that is higher than motor detonation pressure 2 multiplication of voltage power, and described 5 piston rod bodies and 6 journal holes and Engine Matching are installed.Guiding trough of belt 4 assurance mounting point and directions.
Fig. 3 installs plan view for this device; This test is installed in the cylinder sleeve of engine 7 with the high pressure sealing piston, and high-pressure acts on the supporting plane 1 of high pressure oil, and on-load pressure is through connecting rod shank 5; Crankshaft journal hole 6 links to each other with bent axle, is delivered on the engine crankcase wall.Owing to adopt the closure gasket groove and the cylinder sleeve of twice O type circle and back-up ring to seal, can prevent leakage because of cylinder sleeve 7 distortion causing piston edge high pressure oil.
