Abstract
The utility model discloses a hydro-viscous speed adjustment drive device, comprising a speed adjustment main machine, a hydraulic system and a change-over valve, wherein an oil tube of the hydraulic system is connected with the change-over valve, the change-over valve is a three-way change-over valve and another two terminals of the change-over valve are respectively connected with a pressure difference alarm and the pressure difference is respectively connected with a filter core, a proportioning valve and a control switch and the control switch is connected with an oil box. The hydro-viscous speed adjustment drive device continuously operates when the hydraulic control system is in trouble to ensure normal production of the user.
Description
Technical field
The utility model relates to a kind of speed-regulating actuator, especially relates to a kind of liquid_viscosity regulator transmission device.
Background technique
The liquid_viscosity regulator transmission device is a kind of transmission device of realizing the continuous stepless speed governing, it is according to the principle of mechanics of viscous fluids, utilize the liquid viscosity transferring power, carry out speed governing by changing oil slick thickness, be mainly used in the energy-saving speed regulating and the soft start of the medium-and-large-sized blower fans of industry such as electric power, metallurgy, chemical industry, water pump.But present liquid_viscosity regulator transmission device does not have abating protection device, in case friction plate lost efficacy, equipment can only be shut down maintenance, because operating conditions is abominable, faults such as obstruction appear in hydraulic control system easily, cause the shutdown troubleshooting, influence user's ordinary production.
The model utility content
The purpose of this utility model provides a kind of liquid_viscosity regulator transmission device, remains in operation under the situation that can break down in the hydraulic control system of equipment, guarantees user's ordinary production.
For achieving the above object, the utility model provides a kind of liquid_viscosity regulator transmission device, comprise speed governing main frame, hydraulic system and changing valve, the oil pipe of described hydraulic system links to each other with described changing valve, described changing valve is a three-way change-over valve, two ports in addition of described changing valve are connected with the pressure reduction alarm respectively, and described pressure reduction alarm is connected with filter core, Proportional valve and control switch respectively, and described control switch all links to each other with fuel tank.
Therefore, the utility model adopts the liquid_viscosity regulator transmission device of said structure, remains in operation under the situation that can break down in the hydraulic control system of equipment, guarantees user's ordinary production.
Below by drawings and Examples, the technical solution of the utility model is described in further detail.
Description of drawings
Fig. 1 is the utility model liquid_viscosity regulator transmission device embodiment's a plan structure schematic representation;
Fig. 2 is the utility model liquid_viscosity regulator transmission device embodiment's a forward sight structural representation.
Embodiment
Embodiment
Fig. 1 is the utility model liquid_viscosity regulator transmission device embodiment's a plan structure schematic representation; as shown in Figure 1; comprise speed governing main frame 1; hydraulic system 2 and changing valve 3; the oil pipe 4 of described hydraulic system links to each other with described changing valve 3; described changing valve is a three-way change-over valve; two ports in addition of described changing valve are connected with pressure reduction alarm 11 and pressure reduction alarm 21 respectively; pressure reduction alarm 11 is connected with filter core 12; Proportional valve 13 and control switch 14; pressure reduction alarm 21 is connected with filter core 22; Proportional valve 23 and control switch 24; control switch 14 all links to each other with fuel tank 5 with control switch 24; the control system that is hydraulic system in the present embodiment is two cover control system; even like this because operating conditions is abominable; after the faults such as the control system appearance obstruction of hydraulic system; can make entire equipment continue operation by switching controls switch 14 and control switch 24; thereby the equipment of realization on-line maintenance fault has overcome former design defective in this regard, has increased the reliability of equipment.
Fig. 2 is the utility model liquid_viscosity regulator transmission device embodiment's a forward sight structural representation, the lubrication motor 6 of described hydraulic system and control motor 7 all adopt vertical mounting type, the horizontal mounting type that adopts in the relative existing equipment, lubrication motor and control motor adopt behind the vertical mounting type can with oil pump be connected oil pipe and be installed on fuel tank 5 inside, even like this oil pump be connected pipeline leak, fluid also can directly flow back to fuel tank 5, avoided the generation of oil leakage phenomenon effectively, the noise that produces during oil pump operation is simultaneously also completely cut off by fuel tank 5, has reduced the noise of entire equipment.
Therefore, the utility model adopts the liquid_viscosity regulator transmission device of said structure, remains in operation under the situation that can break down in the hydraulic control system of equipment, guarantees user's ordinary production.
It should be noted that at last: above embodiment is only in order to explanation the technical solution of the utility model but not limit it, although the utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that: it still can make amendment or be equal to replacement the technical solution of the utility model, and these modifications or be equal to replacement and also can not make amended technological scheme break away from the spirit and scope of technical solutions of the utility model.
