Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, to make advantage of the present utility model and feature can be easier to be readily appreciated by one skilled in the art, thus more explicit defining is made to protection domain of the present utility model.
Refer to Fig. 1 and Fig. 2, the utility model embodiment comprises: a kind of many turning valves electric device test unit in serviceable life, comprise: support 1 and hydraulic system 100, described support 1 is by upper plate 10, base plate 11 and many root posts 12 assemble, described upper plate 10 is provided with push type dish seat 2, many turning valves electric device 3 is arranged on push type dish seat 2, valve rod 4 is provided with in described push type dish seat 2, described valve rod 4 lower end is by key connecting fastening connecting plate 5, the both sides of described web joint 5 are respectively arranged with guide plate 6, the other end of two pieces of guide plates 6 blocks two heel posts 12 respectively by lining, described valve rod 4 bottom is threaded into pull pressure sensor 7, pull pressure sensor 7 other end is connected with the piston rod 90 of oil cylinder 9 by connecting link 8, be fixed on base plate 11 bottom oil cylinder 9, described oil cylinder 9 is communicated with hydraulic system 100.
Furtherly, be provided with stem nut 20 and the needle bearing 21 of test in described push type dish seat 2, the output shaft of many turning valves electric device 3 is connected by dental inlay with stem nut 20; Described valve rod 4 with stem nut 20 for acme thread is in transmission connection; Two little position-limited racks 60 installed by guide plate 6 on the left of described web joint 5, the guide plate 6 on the right side of described web joint 5 is provided with a large position-limited rack 61; On the left of described support 1, column 12 installs limit switch 13, lower position switch 14 respectively, described support 1 right side uprights 12 is provided with extreme position limit switch 15; The surplus valve 101 for controlling flow is provided with in described hydraulic system 100.
The principle of work of the utility model many turning valves electric device test unit in serviceable life: many turning valves electric device 3(is hereinafter referred to as electric device) when running, electric device 3 output shaft drives stem nut 20 to rotate, valve rod 4 drives guide plate 6 to move up and down along column 12, and drive pull pressure sensor 7, cylinder piston rod 90 move up and down simultaneously.When oil cylinder 9 bottom, oil pocket is full of hydraulic oil, and the surplus valve 101 setting certain pressure makes back pressure to oil circuit, now electric device 3 runs, band ovable valve stem 4 moves down (simulation electric device valve-off), piston rod 90 is driven to move down, the work done of compression cylinder 9 cavity of resorption hydraulic oil, makes hydraulic system 100 pressure increase back down surplus valve 101 drain charge.Otherwise electric device 3 reverse direction operation, band ovable valve stem 4 moves up (simulation Denso opens valve), and drive piston rod 90 to move up, the work done of compression cylinder 9 epicoele hydraulic oil, makes hydraulic system 100 pressure increase back down surplus valve 101 drain charge.
The actual condition of consideration valve opening and closing in operation, underloading is belonged between valve closing stroke 0 ~ 80%, remainder stroke is fully loaded, closes to having established pass to low pressure relief valve during operation, having closed to high-pressure overflow valve two kinds of Pressure relief valves, control conversion by two-position two-way solenoid valve at electric device 3.When closing to operation, when little position-limited rack 60 touches lower position switch 14, two-position two-way solenoid valve action, switch operating oil circuit, at this moment, closes to high-pressure overflow valve as back pressure work.
In addition, hydraulic system 100 parts of electric device life test apparatus are placed on support, and chassis plane distance oil cylinder has certain altitude, makes full use of the potential energy of fuel tank hydraulic oil, when durability test, be full of the upper and lower oil pocket of oil cylinder piston by self-compensating function.In the life test apparatus of high pulling torque many revolutions Denso, oil cylinder oil pocket is by the independent fuel feeding of oil pump.Compare and other power system, the design of this life test apparatus, advanced a lot, improve the operating environment of durability test simultaneously.In Denso durability test, the stress data that we provide according to pull pressure sensor, the constantly back-pressure of adjustment surplus valve, make the load that is subject to during Denso durability test closer to the load of operating mode.
The foregoing is only embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model instructions and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
