 Work two pump wheel and turbine fluid coupling cavity called a double-lumen constant filling fluid coupling.

A double-lumen constant filling fluid coupling structure and its characteristicshydraulic manifolds

(1) the structure of the overall structure of the double-lumen constant filling fluid coupling the wheel by two pumps and two turbines, the middle of the two pump wheel has an intermediate connection body, the inner edge of the pump wheel and turbine auxiliary chamber before two single chamber between the flow holes. The small size double-lumen coupling, does not have the intermediate connection member, each of the two pump wheel outwardly some housing to form a space to accommodate two turbine.

(2) the impeller structure dual-chamber hydraulic coupling impeller structure, there are three:hydraulic adaptors

1) impeller structure with single-cavity coupling identical. Equal to the pump wheel and the turbine of the coupling of two single lumen through the intermediate connecting member and the spindle are connected together.

2) the structure of the impeller wit h single-cavity coupling. Usually cascade depth equal to the a 0.09D shallow cavity, the impeller the middle of a baffle ring 3) stamping welding impeller structure. Cascade is approximately equal to an average depth of 0.08D, and shallow outer deep within, which is conducive to reducing the loss of liquid flow contraction. Impeller with the inner ring in the dual-chamber fluid couplings, but the inner ring shallow characteristics. Plus the inner ring may be in order to increase the contact between each of the blades and blade strength and stiffness.

(3) double-lumen constant filling fluid coupling characteristics.

1) the pump wheel torque coefficient due to the different structure of the impeller, the double-lumen constant filling fluid coupling of the pump wheel torque coefficient are not the same.

Impeller structure is the same as the single-chamber, dual-chamber pump wheel torque coupling coefficient is approximately equal to the single-c hamber times the power transfer is also approximately equal to 1 times the single-chamber.

Impeller structure of a shallow cavity, the pump wheel torque coefficient is not equal to 1 times the single-chamber, but about equal to the conventional single-cavity fluid coupling of 1.4 to 1.6 times. The power transfer is approximately equal to 1.5 times of the conventional single-cavity fluid coupling.hydraulic ferrule

2) overload coefficient from the cavity structure, the dual-chamber constant filling fluid coupling equivalent with front auxiliary chamber constant filling fluid couplings, which have characteristics generally contrast, and thus a higher coefficient of overload, especially zero speed overload factor will be higher. The shallow cavity type of dual chamber hydraulic coupling cavity depth, a low torque coefficient, combined flow blocking tape is disposed, and thus the overload coefficient can be us ed with single-chamber hydraulic coupling, and Tg = 2.5 to 4.

3) fluctuations than overloading the working fluid within the fluid coupling for the crowd ring movement, and by the dynamic pressure burst into the auxiliary chamber before transmitting torque decreased, but after that, no after the auxiliary chamber, so the torque again increased, and thus relatively large fluctuations.

4) the axial force. Often fluid-filled can automatically balance the axial force; dual-chamber coupling outside the fuel supply system, oil pressure and oil line toward different reasons and therefore can not completely eliminate the axial force, but you can greatly reduce the axial force.

5) Transmission characteristics. Based on experience, the dual-chamber constant filling fluid coupling should not be vertical with a vertical with a power transfer is significantly reduced, for example, YOXD360 coupling horizontal use pass the 45KW (input speed 1500r/min), but t he vertical use but can not pass 45KW, even 37KW also passed not. The reason for this phenomenon may be affected by gravity, dual-chamber coupling two uneven filled cavity above the cavity due to the fluid-filled to reduce, so pass power reduction, following cavity fluid-filled too much, but has reached the capacity limit, so the overall pass power down. Inner wheel drive double-lumen constant filling fluid coupling can also be outer wheel drive characteristics had no significant effect.

the constant filling fluid coupling can not all oil-filled reasons

(1) constant filling fluid coupling were full of oil, the temperature of the oil expansion will seal Dingfan, break the seal, they may even coupling housing Splitting.hydraulic hose fitting

(2) in order to start or overload time limit torque rise limit of the auxiliary chamber before the rectangular fluid coupling mostly set side auxiliary chamber, after the auxiliary chamber, at the start or overload through the shunt to the auxiliary chamber, so as to reduce the working chamber the full-charge rate to the low transmission torque. If the coupling cavity is wholly filled with oil, during normal operation, these auxiliary chamber is full of oil when starting or overload, the working fluid can not be diverted from the working chambers, which can not reduce the filling rate of the working chamber of the coupling, also unable to reduce the transmission torque coupling lost overload and delay start function. Constant filling fluid coupling fluid-filled, must be in accordance with the regulations and must not be completely filled.hydraulic fittings suppliers

(3) The test proved that constant filling flu id coupling 80% filling rate has reached the maximum transmission power, filling rate of more than 80% of the power, not only can not improve, they may reduce the power.hydraulic fittings manufacturers

(1) various forms of circulation and circulation diversion

  Constant filling fluid coupling the spiral cavity fluid circulation movement is usually referred to as the circulation. Under different conditi ons, circulation different form, by a circulation patterns called to another circulation patterns into circulation diversions.

(2) circulation hazards and measures to eliminate diversion.hydraulic ferrule

  Circulation diversion coupler features an unstable region, resulting torque oscillation output speed fluctuation phenomena, normal fluid coupling transmission cause harm, and therefore must seek to eliminate.

1) choose a higher filling rate coupler Practice has proved that the filling rate of the unstable region. Filling rate more hazard to the conversion of large circulation by the small circulation, the lighter, the smaller the torque ripple. Instead, the fluid-filled volume gradually decreased, gradually widening the unstable region, gradually increase the torque ripple aggravated harm. Therefore, in the selection should be minimal coupling with or without low filling rate. For examp le, when the coupling of the two specifications can pass the unified power, you should choose a smaller size, higher filling rate coupling, to avoid the impact of the unstable region.

2) the installation of a spoiler in the pump wheel and turbine installation of a spoiler is to eliminate one of the methods of the unstable region.hydraulic hose assemblies

3) the improved blade structure in the inner edge of the pump wheel and the turbine, the blade cutting angle so that the flow for large circulation movement, through the vaneless region increased to a certain extent, can also reduce the torque when the large circulation, to reduce the characteristics destabilizing effects. Some improvements in turbine design, take the length of the same blade or size composite cavity, can also abate the impact of the large circulation, reduce the coupling low speed ratio of torque.hydraulic hose fitting

Their structural principle can be divided into the built-in centrifugal slider friction clutch-type, built-in the floating wedge friction clutch type and external centrifugal fly block friction clutch-type, built-in four kinds of hydraulic clutch.

Latching the advantages of hydraulic coupling:

1 run at rated conditions, speed 1, the fluid coupling did not slip losses, the efficiency is approximately equal to 100% energy saving.

2, changing the amount of coupler filled, the regulatable promoter in the case of constant input rotation speed, acceleration time and the transmission torque.hydraulic adapters

In the start segment by the fluid coupling play a role in the startup performance.

O verload, the friction clutch slip, play a security role; further overload, the friction clutch disengaged coupler role of effective overload protection.

Friction clutch to the friction power loss is smaller, in the lockout process temperature rise is small, small wear, longer life expectancy.

Disadvantages:

1, a coupler structure is more complicated, and the cost is relatively increased.

2, built friction clutch lock coupler, due to the friction ring sleeve bonding of friction material wear out in a long-term work, and so over the contaminated oil in the coupler, and effect on bearing life in the coupler.

   Because sometimes do not exactly match the actual operating conditions and calculation conditions, the amount of fluid-filled selected according to the calculation condition may not be suitable for the requirements of the actual operation. For example, transfer of power, the overload factor are likely to be different, which must pass debug to verify the correctness of the fluid-filled, the validation of the project and the method is as follows.

    Rated speed verification method: work machine running at full capacity, with the rotational speed of the the tachometer measurement coupler output shaft or work machine spindle, if nT ≥ 0.96 nd (nT coupling output speed, nd motor speed), then the coupling torque (rated torque is not less than the rated load of the work machine work work machine rated torque rated torque is less than if the coupling, the coupling can not be working at nominal operating conditions, we must increase the slip to reduce the output speed). The coupling rated output speed below standard. The description of the fluid-filled inadequate, appropriate adjustments retry.

    Overload validation experience positive a s followshydraulic fittings manufacturers

(1) working machine or constant filling fluid couplings turbine brake, check the motor overload current, and calculated torque motor overload. If within the allowable range, then the suitable coupling overload coefficient, if the motor overload torque is too large, then the the coupling liquid filled excessive amount appropriate to reduce the fluid-filled retry.china hydraulic hose

(2) the working machine or constant filling fluid couplings turbine brake, measurement speed motor overload, if the motor overload speed ndj = (0.97 ~~ 0.95) nd (nd overload coupling factor for motor rated speed) qualified. If ndj <0.95, nd, excessive amount of coupling fluid-filled if ndj> 0.97nd coupling fluid-filled volume is too small.hydraulic hose and fittings

    Extended sta rt-up time to verify authentication method is as follows: In the process of working machine starts, check the start time. If the start time is too fast, the liquid filled excessive, and if the start-up time is too long, indicating that the liquid filled amount is too small, after adjusting the liquid-filled amount retry until pass up.

Multi-drive coupling filled correctness verification method is as follows

(1) measured with an ammeter various motor running current, the current description of the amount of coupling is filled, by force; low current couplings liquid filled less force is small. Appropriate adjustments since the fluid-filled, until the current basic balance date.

(2) observation of the synchronous operation of the multi-machine drive, high output speed coupling may be appropriate to put a little oil, add a little oil or low output speed coupling appropriate.

(3) measured state coupling output speed, high output speed p ut a little oil should be slightly lower output speed should be a little oil.

 Capable of supporting vertical mounted vertically with vertical mechanical fluid coupling known as the vertical hydraulic coupling. Their classification with the following features:

A vertical hydraulic coupling classificationhydraulic hose

By fluid-filled way, the vertical coupling can be divided into common type, constant filling vertical hydraulic coupling and variable speed vertical hydraulic coupling; divided by type of drive, the vertical hydraulic coupling can be divided into directly connected both transmission and parallel transmission; coupling and power machine installation location points, the vertical fluid couplings can be divided into sitting and hanging stand two.

(1) sitting. The coupling is sitting above the motor.

(2) hanging legislation. The coupling is hanging below the motor.hydraulic manifold block

    Variable speed hydraulic coupling by structural constraints, only hanging Vertical did not sit Vertical, motor coupling above the working machine below the coupling.

B vertical structural characteristics of the fluid coupling

     On the surface, it seems that the vertical hydraulic coupling is used horizontal hydraulic coupling stand up, it is not true, vertical hydraulic coupling has the following characteristics:

(1) coupling down one end of the seal should be strengthened. The horizontal coupling at work, most of the working fluid to work in a loop round at the outer diameter, so the possibility of leakage of the spindle center portion. Vertical coupling mounted vertically, by gravity, down the possibility of leakage of the working fluid. To prevent leaks, must be reliable seal structure, some down one end plus casing.

(2) auxiliary chamber belowhydraulic couplings

1) before the coupling is not started, in the bottom of the auxiliary cavity is filled with the working fluid, and thus reduces the rate of the oil-filled working chamber, so that the starting torque is reduced , the start becomes smooth and soft. Conversely, if the auxiliary chamber is located at the start of the above coupling, the working chamber 100% oil-filled, so that the starting torque and increase the impact and start work machine is not conducive to a smooth start.

2) working fluid overload circulation movement, rely on dynamic pressure and gravity quickly leaked into the bottom of the auxiliary chamber, in a timely manner to protect the motor and work machine from damage when overloaded. If the auxiliary chamber at the top, overloading the liquid flow direction of movement opposite to the direction of the auxiliary chamber, the need to rely on the static pressure to overcome gravity and push the liquid to the top of the auxiliary chamber, and thus the discharge of slow, not as good as the auxiliary chamber below the coupling is sensitive.

3) should be located in the top of the fill plug and fusible plug. Should be set up for the convenience of refue ling and demolition fusible plugs, fuel plug and fusible plug at the top. Below should also be set to put the oil drain plug for oil change. Usually the refueling position of the mouth of vertical coupling is exactly the location of the 80% oil-filled.
