Description
Technical field
The utility model relates to a kind of dynamic balancing high temperature hydraulic test device.
Background technique
At present, the used hydraulic system of logger must be in the environment of high temperature (up to 200 ℃) reliably working, for guaranteeing that instrument can must carry out the high-temperature operation experiment to instrument, to confirm the functional reliability of this instrument under the condition of high temperature at reliably working under the hot environment before work.Carry out high temperature experiment, just need to use high temperature hydraulic oil, generally adopt high temperature pump from fuel tank, to extract and provide high temperature hydraulic oil to instrument.This just need be placed into high temperature pump and motor in the fuel tank of high temperature hydraulic oil.The fuel tank of use is open oil groove in the present high temperature experiment, because the volatilization of high temperature hydraulic oil is severe, the gas toxicity of being volatilized is bigger, has carcinogenic possibility, so use open oil groove bigger to the human injury.In addition, people are confined to the normal temperature state for the relation of hydraulic oil volume and pressure usually, do not understand for the relation of hydraulic oil volume and pressure under the condition of high temperature, during especially specific to a temperature value, have no way of especially learning.This just makes that experiment has certain blindness, also can be not enough owing to hydraulic oil condition of high temperature downforce state is prepared, cause line fracture, and bring the tremendous economic loss.
The model utility content
The technical problems to be solved in the utility model provides a kind of high temperature hydraulic oil volatilization and can testing hydraulic innage temperature state lower volume and the dynamic balancing high temperature hydraulic test device of pressure dependence of preventing.
In order to address the above problem, the utility model provides a kind of dynamic balancing high temperature hydraulic test device, comprising:
Sleeve, described sleeve is provided with the pouring orifice that is used for oiling in described sleeve, and described pouring orifice is provided with detachable sealing screw;
End cap, described end cap fixing seal are arranged on described sleeve one end, and described end cap is provided with port connection that is communicated with inside and outside oil circuit and the pressure-bearing electric coupler that is communicated with interior external circuit;
Piston, described piston slipper seal suit are arranged on the interior end away from described end cap of described sleeve.
Further, also be provided with the afterburning structure that is used for the described piston of push-and-pull on the described piston.
Further, described afterburning structure comprises the bolts and nuts of pair of matched, and described bolt connection is arranged on the side of described piston away from described end cap, the detachable fixedly connected described sleeve of described nut.
Further, also be provided with the motor that is used to export the high temperature pump of high temperature hydraulic oil and power is provided for described high temperature pump in the described sleeve, with controlled, described high temperature pump is exported high temperature hydraulic oil by described port connection to the outside to described motor by described pressure-bearing electric coupler energising.
The utlity model has following advantage:
1, the utility model adopts sleeve, end cap and piston, has not only realized the sealing to high temperature hydraulic oil, prevents the hydraulic oil volatilization, but also can dynamically adjust the shared volume of this high temperature hydraulic oil, balanced hydraulic oil pressure.In addition, but by to the monitoring of the piston active state relation of testing hydraulic innage temperature state lower volume and pressure also.
2, the utility model also can be exerted pressure to the hydraulic oil in the utility model according to actual needs voluntarily.
Description of drawings
Below in conjunction with accompanying drawing mode of execution of the present utility model is described further:
Fig. 1 shows a kind of dynamic balancing high temperature of the utility model hydraulic test apparatus structure schematic representation.
Embodiment
As shown in Figure 1, the utility model comprises sleeve 1, end cap 2 and piston 3.Sleeve 1, end cap 2 and the piston 3 inner cavitys 8 that form a sealing, filled high-temperature hydraulic oil in this cavity 8.
Also be provided with the high temperature pump 7 that is used to export high temperature hydraulic oil in the sleeve 1 and for high temperature pump 7 provides the motor 6 of power, motor 6 by 22 energisings of pressure-bearing electric coupler with controlled, high temperature pump 7 by port connection 21 to outside output high temperature hydraulic oil.
When using the utility model monitoring instrument, starting electrical machinery 6 and high temperature pump 7 provide high temperature hydraulic oil to the utility model external instrument.This moment, hydraulic oil can not volatilize, and was completely enclosed within the sleeve 1, had realized the environmental protection of experiment.
Piston 3 suits are arranged on sleeve 1 an interior end away from end cap 2, can slide in sleeve 1.Carry out slipper seal by seal ring is set between piston 3 and the sleeve 1, prevent hydraulic fluid leak in the sleeve 1.Piston 3 can slide by exert pressure push-and-pull piston 3 of the external world, also can pass through the effect of internal hydraulic pressure oil pressure, thrust piston 3 slips.
The utility model adopts sleeve 1, end cap 2 and piston 3, has not only realized the sealing to high temperature hydraulic oil, prevents the hydraulic oil volatilization, but also can dynamically adjust the shared volume of this high temperature hydraulic oil, balanced hydraulic oil pressure.In addition, but by to the monitoring of the piston 3 active states relation of testing hydraulic innage temperature state lower volume and pressure also.
In the utility model, also be provided with the afterburning structure 4 that is used for push-and-pull piston 3 on the piston 3, so that piston 3 is carried out the push-and-pull operation.The utility model also can be exerted pressure to the hydraulic oil in the utility model according to actual needs voluntarily.
