Fluid coupling between the input shaft and the output shaft by liquid contact

Fluid coupling between the input shaft and the output shaft by liquid contact, work does not exist rigid connection between components. Hydraulic coupling features are: to eliminate shock and vibration; output speed lower than the input speed, two-axis speed difference with the increase of the load; overload performance and good starting performance, Hydraulic hose fittings  load is too large to enter when stalled still rotating shaft, without causing damage to the power machine; when the load decreases, the output shaft speed increases until close to the input shaft speed. Hydraulic coupling transmission efficiency equal to the output shaft speed multiplied by the output torque (power output) and the input shaft speed multiplied by the input torque (input power) ratio. General hydraulic coupling normal operating conditions when the speed ratio above 0.95 can obtain higher efficiency. Because of the characteristics of the fluid coupling working chamber and the pump wheel, and the shape of the turbine are different. If the oil vent fluid coupling, coupler is in disengaged state, can play the role of the clutch.

Fluid coupling

Fluid coupling fluid as the working medium in a non-rigid couplings, also known as hydraulic couplings. Hydraulic coupling of the pump wheel and turbine liquid can form a closed working chamber circulating pump wheel mounted on the input shaft, turbine mounted on the output shaft. Power machine (engine, electric motor, etc.) to drive the input Hydraulic ferrules rotates, the liquid is thrown centrifugal pump wheel. This high-speed fluid into the turbine after the turbines rotate the energy obtained from the pump wheel to the output shaft. Finally liquid return pump wheel, forming a cycle of flow. Hydraulic coupling by the liquid and the pump wheel, turbine blades interaction of the change in angular momentum transfer torque. Its output torque equal to the input torque minus the friction torque, so that its output torque is less than the input torque constant.

Hydraulic coupling

Fluid coupling is an energy-consuming mechanical control devices, speed deeper (lower speed) the greater the loss, especially constant torque load, since the original transmission input power constant, the speed loss into a loss of power ratio increases. For fan and pump load,  Hydraulic adapters load torque at speed squared rate changes, the original transmission input power measured at the square of speed decreased, loss of power is relatively small, but the output power is reduced by the cube of speed ratio, speed efficiency is still low. Governor hydraulic coupling efficiency curve shows the average efficiency of around 50%

Fluid coupling model works

is a hydraulic coupling passing the liquid medium speed machinery and equipment, and its active input shaft is linked with the original conveyor, driven output shaft and load shaft coupling, by adjusting the pressure of the liquid medium, so that the output shaft speed to be changed. Ideally, when the pressure tends to infinity, the output speed and input speed is equal to the equivalent steel couplings. When the pressure decreases, the output speed is reduced accordingly, continuously changing the medium pressure, the output speed can be lower than the input speed steplessly. Fluid coupling Hydraulic ferrules power control speed and efficiency of the principle of fluid coupling according to the above characteristics, can be equivalent to the model shown ispeed power control principles that drive speed changes, in essence, the result of mechanical power adjustment. Therefore, the output speed of the hydraulic coupler reduced, the actual output power is reduced. The governor during the original transmission fluid coupling speed does not change, assuming constant load torque, the original mechanical power transmission remains unchanged, then the difference between the input power and output power go of it, apparently by hydraulic coupling in the form of heat loss out. Therefore, we can not simply that hydrodynamic coupling speed is "lost turn", while the actual power is lost. Let the original transmission power of PM1, the output power of PM2, loss of power was is a fluid coupling energy-consuming mechanical control devices, speed deeper (lower speed) the greater the loss, especially constant torque load, since the original transmission input power constant, the speed power loss loss increases proportionately. For fan and pump load, the load torque at speed squared rate changes, the original transmission input power measured at the square of speed decreased, loss of power is relatively small, but the output power is reduced by the cube of speed ratio, speed efficiency is still low. Governor hydraulic coupling efficiency curve shows the average efficiency of around 50%

In the high-pressure hose for withholding, you always will have withheld too tight or too loose phenomenon, and these phenomena often lead to an adverse effect on high-pressure hose. Today we say that it would withhold the amount of the size of what impact Hydraulic pipe fittings. We carried out through the following detailed understanding.High pressure hose and fittings assembly and withhold the amount of the withholding rate of improper selection or joint structure and material, size selection is unreasonable, can lead to high pressure hose and fittings withholding too tight or too loose, the joints can cause early damage.Assembly, if the withholding amount is too small, the high pressure hose between the connector and the weight is too loose, the role of the hydraulic pressure hose during the initial period there may emerge from the connector; if withholding excessive, fittings and hose too tight, easily lead to localized damage the hose inner being, cracks, pressure oil from the ruptured directly into the wire layer, and then he went along the gap between the wire coat tail spray, or until he went somewhere along the wire layer build up, so thatHydraulic adapters drum kits produced even rupture. Hose and connectors in the assembly, if the withholding too fast, easy to cause damage to the inner rubber layer and wire breakage, so that premature failure of the hose in use.The above information is very detailed description of the size of the amount withheld for the use of high pressure hose impact, so we should use this withholding considerable attention, he dosage size is accurate, whether the mutation will produce high pressure hose, etc. issues that should be close attention.

contact with high pressure hose

A micro oil-resistant high-pressure hose.Such high pressure hose, mainly used in coal mine hydraulic bracket, dosage particularly large, some large mines, the amount to tens of millions a year, and say it is very terrible, there are times, I Inner Mongolia, in a large warehouse to see mine that a lot of high-pressure hose, looks like a hill heap. In particular, some caliber 152, and 204 large winding hose, each root to all kind of scary to see the value of money. That fight was convinced Hydraulic pipe fittings isquitelarge.Secondly,interms of performance and practical with low agricultural equipment.Second, high oil and high-pressure hosSuch high pressurehose,mainlyusedinconstructionmachinery, the use of high strength, high frequency. Strong corrosion resistance and pressure resistance. We can see a lot of construction vehicles, Jic hydraulic fittings, particularly evident, it is now everywhere, not only that, the excavator head is getting bigger, the job has become increasingly pursuit of high intensity, heavy, frequent trend.

High pressure hose hidden precautions

First, choose a brand, quality assurance of enterprise, quality assurance, sales and service companies have good general manufacturing, high quality requirements.Second, pay attention to high-pressure hose assembly installation and operation. Not blindly cut production.Third, the high-pressure hose for industrial products, the use Hydraulic hose fittings be aware of their required product specifications. Blindly buy is one of the factors causing quality problems.Fourth, as the user, but also pay attention to high-pressure hose storage conditions.

risk factors of high pressure hose

Two. Operation using unreasonable: the premise of quality assurance, if used properly, will greatly shorten the high pressure hose to life. Practical work, much of the damage is dueJic hydraulic fittings hose caused by improper use. (A) subject to frequent and intense pressure shocks. High pressure hose to burst, not generally caused due to too much pressure under static, but with the stress intensity and frequency of shocks related. Construction machinery in operation, hydraulic tubing will be repeated sudden increase or decrease, and thereby constitute a frequent tubing pressure shocks, resulting in damage to seals ministries intensified, blistering and cracking high-pressure hose and fittings loose leakage. Therefore, in operation, the valve stem can not be pulled too much, must be gentle. (2) use of the oil temperature. Engineering machinery operation, the hydraulic system power loss due to fluid leaving the heat, coupled with the impact of the outside temperature (especially in the summer), make the oil dramatically. Fluid temperature is higher, the more easy to aging rubber elasticity variation, strength and sealing performance, high pressure hose will soon burst. Thus, in operation, when the hydraulic system in the temperature is too high, too fast, it is timely to identify the reasons, be excluded; summer jobs, especially in continuous operation, should take the necessary measures to cool. (3) high-pressure hose selection, installation is unreasonable. Hydraulic pipe fittings the high-pressure hose, high pressure hose chosen length of wire layers, joints must be reasonable shape and size, and should minimize the degree of bending of high pressure hose; tighten the connector nut, do not allow high pressure hose distorting, too large bending and twisting will greatly reduce the service life of high-pressure hose; prone to some friction parts should take protective measures to prevent high pressure hose wire layer due to wear and impact. Furthermore due to wire corrosion, reducing wear thin led force, causing burst.

risk factors of high pressure hose

First, the manufacturing quality is poor(A) high-pressure hose is oilresistant rubber inner tube wall, in the middle of braided steel wire (steel braided hose) or winding wire (wire winding hose). Poor quality of the hose will appear: plastic wall of uneven thickness; steel braided too tight (wire stroke is small), too loose (steel travel large) or wire root too few; hose pressurized deformation (elongation, shortening or bending deformation) larger (national standard steel stroke control of plus or minus 3); airtight plastic outer lead Hydraulic pipe fittings (main manifestations: Lu steel); inner plastic seal is poor leaving the high pressure oil easily into wire layer; adhesion layer and layer of wires inadequate. The above conditions can cause the hose to withstand reduced, eventually appears at the wall of the weak burst. Especially in the inner layer, poor air tightness, then a pressure, it leaks, then the pressure directly burst.(2) high-pressure hose and connector assembly withhold the amount and mode selection withheld improperly. Or joint structure, material, size Hydraulic tube fittings, can lead to pressure hose and fittings too tight or too loose, causing early damage joints. Assembly, if the withholding amount is too small, that withhold joints between the weight of too loose with the hose when under the effect of the hydraulic hose during the initial period there may emerge from the joint; withheld if excessive, then withhold joints and hose too tight, easily lead to the hose inner layer of localized damage, deformation, cracks, high pressure oil from the weak rupture directly into the layer of wires, and then he went along the gap between the wire coat tail ejected, or along the wires of the layer has been Somewhere he went to build up, so that the outer plastic drum kits produced even rupture. Hose and connectors in the assembly, if the withholding too fast, easy to cause damage to the inner rubber layer and wire breakage, so that premature failure of the hose in use. In addition, the joint design is unreasonable, jerry, processing of poor quality, can also cause damage to the inner glue; if improperly fitting material selection, not reach high pressure hose assembly requirements. Will shorten the life of high pressure hose.

intubation accounted

According to statistics, intubation accounted for about 30% of the total number of forgings, the establishment of intubation CAD ​​/ CAM system is a rewarding job. Meanwhile, intubation Jic hydraulic fittingsJic hydraulic fittings, easy descriptions and definitions, so early intubation CAD ​​/ CAM systems most of these die from the start. Currently, intubation CAD ​​/ CAM system has entered the practical stage. System include: forging design, shape description, forging fixture design, drawing die, NC NC program preparation.Intubation working part of the mold, such as mold cavity is designed according to the shape of the product components.

Mold CAD / CAM process plan involvesHydraulic ferrules Hydraulic ferrules the mold structure and content such as NC programs. Intubation process analysis and process scheme is based on the determination of intubation process feature geometry and based on complete. Mold structure designed especially for working parts mold design, depends on the shape of intubation. In the mold structure design, geometric modeling system based on established products geometric model, you can complete concave cavity and punch shape design, the resulting mold surface for the mold machining to provide a foundation. In addition to working part shape design, the shape of the mold parts designed to use the same geometric modeling techniques. Prepared by the machining program to determine the machining tool trajectory, but also need to establish mold parts geometry. Therefore geometric modeling is mold CAD / CAM is a key issue for achieving mold CAD / CAM foundation. Degrees.
