Abstract
The invention is a delay coupler, comprising electric motor input flange, after auxiliary chamber cover, pump wheel, rotating casing, turbine, output shaft, connection channel and flow regulating valve, where the electric motor input flange, after auxiliary chamber cover, pump wheel and rotating casing are fixedly connected into an organic whole, the turbine and output shaft are fixedly connected into the other organic whole, two ends of the connection channel are mouthed at the after auxiliary chamber cover and the pump wheel, and the flow regulating valve is arranged on the connection channel. The invention regulates the speed and time of the working liquid entering in the working cavity, thus achieving the delay starting effect, meeting the usage demand of large inertia machine.
Description
Technical field
The present invention relates to a kind of coupler, belong to hydraulic transmission technology field.
Background technique
Because hydraulic transmission component has and improves transmission quality and energy-conservation function, so be widely used, used hydraudynamic drive on now existing over one hundred kind of machinery, all obtained significant technical economic benefit.Hydraudynamic drive is mainly used in industries such as automobile, engineering machinery, mining machinery, petroleum machinery, chemical machinery.Hydraulic transmission component commonly used is a fluid coupling, and its basic theories is that basic flow of working medium in coupler is to flow in the active chamber and the outer mobile velocity field in chamber, and its velocity field is decided by the geometric parameter of coupler basic structure.Load limiting type of constant filling fluid coupling has following handling characteristics as a kind of common fluid coupling:
1. improve the startability of motor, improve the electric motor starting ability;
2. protection motor and equipment prevent motor overload;
3. smooth starting load reduces impact and vibrations in the running;
4. the mean allocation of load in the time of coordinating the multimachine driving when multi-machine parallel connection moves.
The main application area of load limiting type of constant filling fluid coupling is as follows:
1, conveying mechanism, elevating mechanism, Hoisting Machinery;
2, mining machinery.
The performance characteristics of load limiting type of constant filling fluid coupling is to utilize the Maximum Torque of motor to come starting load, realizes startup rapidly, but is difficult to adapt to the machinery of big inertia.For example centrifugal machine starts the restriction that will be subjected to mechanical strength and other operating modes at short notice, must carry out slowly to start.And the coupler that can satisfy this type of demand do not arranged at present as yet.
Summary of the invention
The object of the present invention is to provide a kind of time delay type coupler, geometric parameter by redesign fluid coupling basic structure, the dimensionless performance of its time delay type coupler and the performance characteristic of work mechanism are matched, reach the start-up course that prolongs work mechanism, guarantee the reliability of whole transmission device.
For reaching above-mentioned purpose, the present invention adopts following technological scheme,
A kind of time delay type coupler, comprise motor input flange, back accessorial housing cover, pump impeller, transcapsidation, turbine, output shaft, connecting passage and flow control valve, wherein said motor input flange, back accessorial housing cover, pump impeller and transcapsidation are fixedly connected into an integral body, described turbine and output shaft are fixedly connected into another integral body, the two ends of described connecting passage are opened on back accessorial housing cover and pump impeller respectively, and described flow control valve is located on this connecting passage.
The present invention regulates by Flux Valve Control and enters the speed and the time of the working liquid body in the active chamber, thereby has reached the effect of delayed startup, has satisfied the mechanical user demand of big inertia.
Description of drawings
Fig. 1 is an embodiment of the invention time delay type coupler structural representation;
Fig. 2 is the A portion enlarged view of Fig. 1.
Embodiment
As shown in Figure 1 and Figure 2, a kind of time delay type coupler, comprise motor input flange 1, back accessorial housing cover 2, pump impeller 3, transcapsidation 4, turbine 5, output shaft 6, connecting passage 7 and flow control valve 8, wherein said motor input flange 1, back accessorial housing cover 2, pump impeller 3, transcapsidation 4 are fixedly connected into an integral body, described turbine 5 and output shaft 6 are fixedly connected into another integral body, certain clearance is left on pump impeller 3 and turbine 5 planes, does not have direct mechanical connection between two integral body.The two ends of described connecting passage 7 are opened on back accessorial housing cover 2 and pump impeller 3 respectively, and described flow control valve 8 is located on this connecting passage 7.
After active chamber injected working solution, when prime mover drove pump impeller 3 rotations, working solution obtained kinetic energy and pressure energy under the drive of pump impeller 3 blades, formed the liquid of high-voltage high-speed and rushed at the blade of turbine 5, made turbine 5 follow pump impeller 3 to rotate in the same way.Pump impeller 3 is the kinetic energy and the pressure energy of the mechanical energy conversion liquid of input, the mechanical energy that turbine 5 then can convert the kinetic energy and the pressure of liquid to output again, thus realize the transmission of power.
Compare with existing load limiting type of constant filling fluid coupling with power, the present embodiment time delay type coupler suitably strengthens oil reserve, enters the speed and the time of the working liquid body in the active chamber by flow control valve 8 regulating and controlling, thereby has reached the purpose of delayed startup.
Below common fluid coupling and coupler of the present invention, on the butterfly seperator, be applied as its delay performance of example explanation.Comparing result is as shown in table 1.
| Type | Power (unit) | Rotating speed | Former inrush current peak value | Existing inrush current peak value | Former starting time | Existing starting time |
| The butterfly seperator | 15kw | 1480r/min | 60A | 40A | 90 seconds | 200 seconds |
As can be seen, the embodiment of the invention-time delay type coupler can prolong starting time and the current peak when reduce starting effectively from this table.
