The basic points of the Directional Coupler assembly process
The Directional Coupler consists of many components. These parts must be assembled into a product to complete the assembly process. The process of completing these components is called the assembly process.
The assembly process of the Directional Coupler is relatively simple compared to other Directional Couplers, and the assembly of the torque type Directional Coupler is basically applied to the interchange method, the dispensing method, the repairing method and the adjusting method. Regardless of the type of process used, the assembly process is basically the same point.
Due to the different production capacity and conditions of the enterprise, the Directional Coupler assembly process will be different in the actual operation. But in any case, the basic process requirements are the same, otherwise it can not meet the requirements of the Directional Coupler and factory test.
The working chamber of the coupling is filled with a certain amount of working fluid (usually No. 20 turbine oil). The working wheel pump obtains the mechanical energy from the motor and converts it into liquid energy to promote the rotation of the turbine. The turbine can convert the liquid into mechanical energy. Output, drive the work of the machine work, from time to time, to achieve from the prime mover to the work machine between the energy transfer.
Adjustable Directional Coupler is able to speed control, through the coupling inside the catheter to change the opening degree of the catheter, thus changing the working fluid within the working fluid filling, in the case of constant motor speed, the realization of the machine without Level control, change the size of the output power. Because the transfer of energy changes, resulting in slip, will make the working fluid heat, it must be equipped with a cooler to cool the working fluid. Couplings are equipped with electric actuators and electric manipulators, and load changes in the signal connection, according to user requirements with automatic speed device. Can achieve speed control remote control or automatic control.

The working fluid of the Directional Coupler is the medium that transmits the torque of the coupling, and how much of the Directional Coupler is filled with the coupling torque and the overload protection.
For the same type and specifications of the coupling, the amount of liquid filled directly affect the size of the coupling torque transmission. Its basic law is in the provisions of the liquid filling range, the more liquid filling the more the coupling torque is greater. When the transmission torque is constant, the more the liquid charge amount, the higher the efficiency of the Directional Coupler, but the starting torque will increase at this time, the overload factor will be correspondingly increased. You can use a different amount of liquid, so that the same specifications of the coupling with several different power motor to match the different requirements of the work machine.
The Directional Coupler's fuel supply with the specified Directional Coupler has its own transmission torque range, known as the power band, the power band with the coupling liquid filling range corresponds. Normally, the Directional Coupler should have a fill range of 60% to 80% of the total volume of the coupler, which can not be exceeded and can not be filled. When the Directional Coupler filling capacity of more than 80% of the volume, the coupling in the rotation, due to overload and rapid temperature rise and pressure, resulting in the expansion of the working fluid volume, the coupling of the internal pressure increases, it will destroy the seal , Causing leakage, and even cause the coupling of the shell cracking, resulting in mechanical damage.
Directional Coupler assembly, the factory test qualified, they have to enter the paint painting process. Its purpose is to make the product has anti-rust, anti-corrosion, beautiful effect. This process seems simple, but to achieve the purpose of the process is very complex, the process of each step is very important process, the specific process requirements are as follows:
1) Before painting the product surface of the burr, Phi front, convex and the transit process of damage to the site of the damaged to meet the requirements.
2) with banana water or gasoline or kerosene, cleaning, wiping the surface of the product throughout the fingerprints, dust, paint, etc., and dry the surface.
3) easy to melt plug, explosion-proof plug end face and nameplate, dipstick, oil mirror, logo, marking, etc. to retain the original color, the original parts or parts to be coated with butter or paper cover, to prevent paint color, And then removed.
4) speed control coupling products to spray primer, fill ash, grinding ash, cleaning, spray paint, must be strictly in accordance with the implementation process.
