Directional Coupler Should Be Checked And Maintained On A Regular Basis
Sep 01, 2017

Directional Coupler should be checked and maintained on a regular basis
Directional Coupler to regularly check the tank oil level and timely replenishment of the oil, the new machine for the first time after 500 hours of operation should be removed from the oil filter filter cleaning, combined with the work machine downtime for maintenance, regular cleaning oil pump and oil filter, to regular Check the oil quality, the timely replacement of qualified work oil; if the Directional Coupler box of oil drained, you can unscrew the box input, the output of the lower part of the drain hole plug, can also be loaded at the drain hole The
Directional Coupler if there are quality problems, generally can be divided into two categories, one Directional Coupler leakage leaking phenomenon, the second is the Directional Coupler bearing damage.
Leading to bearing damage for several reasons, one bearing quality failed. Second, the Directional Coupler itself is not good balance, causing vibration, the third is the intensity of the field installation is not good. Fourth, the field installation coaxial degree is not good. In order to solve the above problems, the Directional Coupler achieves or even exceeds the quality of the original imported product. Can do the following treatment: First, the sealing problem, the use of imported seals. Second, the bearing problem, the use of imported bearings. Third, the Directional Coupler whole dynamic balance processing.
Directional Coupler Spare Parts Directional Couplers are usually made of aluminum alloy and are not allowed to be tapped directly with hammers, regardless of installation and removal. Installation should be in the machine and the engine shaft coated with grease. There are special installation and removal tools. Linearly connected Directional Coupler should pay attention to test and correct the coaxial axis of the motor shaft and the working shaft, flexible coupling of the Directional Coupler, coaxial degree tolerance should be less than 0.3mm below the larger Directional Coupler specifications , The higher the power machine speed, coaxial degree of tolerance should be smaller. The pulley-type Directional Coupler is usually cantilevered on the power shaft, fixed with a tightening bolt, and the bolts should be reversed to the power steering. The factory design of the Directional Coupler with a removable screw hole, with a special screw when the demolition of the Directional Coupler from the top of the machine shaft down. Generally use oil medium. Working fluid Recommended: hydraulic oil, hydraulic transmission oil, refrigeration oil, motor oil, mechanical oil. Coal mine application Directional Coupler using water and flame retardant liquid as the medium. Directional Coupler output steering is consistent with the power steering, the power machine can be reversed, but should avoid a sharp reversal reversal. The maximum amount of liquid is not allowed to exceed 80% of the total volume. Regularly check the quality of the working medium and the elastic block of the friction, the timely replacement.
Couplings, also known as couplings, are mainly used to connect the transmission shaft of each mechanism. Due to the different mechanical equipment, the function of various couplings is also slightly different, such as in the forklift coupling is used to transmit the transmission and drive The power between the bridges. 3t below the forklift due to the longitudinal dimension of the transmission system is short, generally using rigid connection structure, that is, from the engine - clutch - transmission - coupling shell - drive axle are bolted, that is, from the engine to the drive axle is a rigid overall Rigid overall middle, using gear coupling.
Directional Coupler repair by filling the way, vertical Directional Coupler can be divided into ordinary type, limited moment vertical Directional Coupler and speed control type vertical Directional Coupler; according to the type of transmission, vertical Directional Coupler Divided into direct drive and parallel drive two; according to the Directional Coupler and power machine installation location points, vertical Directional Coupler can be divided into two kinds of sitting and hanging. Vertical couplers that can be vertically mounted vertically with vertical mechanical couplings are called vertical Directional Couplers. Its classification and characteristics are as follows:
The variable speed Directional Coupler is limited by the structure, and only the vertical type is not mounted, that is, the motor is above the Directional Coupler, and the working machine is below the Directional Coupler.
Vertical Directional Coupler structural features From the surface point of view, it seems that vertical hydraulic coupling is a horizontal Directional Coupler stand up to use, Directional Coupler to the next end of the seal to be strengthened. Horizontal Directional Coupler at work, most of the working fluid in the circular circle diameter work, so the spindle center of the possibility of leakage is small. The vertical Directional Coupler installed vertically, by gravity, the possibility of working liquid leakage down. In order to prevent leakage, must use a reliable sealing structure, and some to the next end of the cover.
