Why more and more customers choose domestic Repeater?
The relay is a kind of hydraulic transmission device which uses the kinetic energy of the liquid to carry out the energy transfer. It uses the liquid oil as the working medium to transform the kinetic energy of the mechanical energy and the liquid through the pump wheel and the turbine, thus connecting the prime mover and the working machine Power transmission.
Foreign Repeater supply cycle for 6-12 months or so, from the order, office, production, customs, delivery, are very inconvenient, and domestic Repeater supply cycle is only about a month, you can achieve Delivery.
Foreign Repeater ordered accessories and wearing parts for a long time, and domestic Repeater can be achieved stock. Foreign Repeater if there are quality problems, aftermarket is very cumbersome. Communication will take a long time, come is even more distant thing. And domestic Repeater are at least "three bags" year, there are quality problems, in two months can reach the scene, communication is very convenient.
Speed-type Repeater if there are quality problems, generally can be divided into two categories, one relay leak oil leakage phenomenon, the second is the relay bearing damage.
Leading to bearing damage for several reasons, one bearing quality failed. Second, the balance of the Repeater itself is not good, causing vibration, the third is the strength of the site installation is not good. Fourth, the field installation coaxial degree is not good.
Foreign Repeater supply cycle for 6-12 months or so, from the order, office, production, customs, delivery, are very inconvenient, and domestic Repeater supply cycle is only about a month, you can achieve Door-to-door, foreign Repeater ordering accessories and wearing parts for a long time, and domestic Repeater can be achieved stock. Foreign Repeater and accessories, sales price is about 10 times the price of domestic Repeater, domestic Repeater can meet the requirements of the use of the site, the localization of the country and enterprises can save a lot of money to improve the business Economic benefits.
The pump wheel and the turbine of the Repeater form a closed working chamber which allows the liquid to circulate, and the pump wheel is mounted on the input shaft and the turbine is mounted on the output shaft. When the power machine drives the input shaft to rotate, the liquid is thrown out by the centrifugal pump wheel. This high-speed liquid enters the turbine and then drives the turbine to rotate, passing the energy from the pump wheel to the output shaft. The final liquid returns to the pump wheel, forming a cycle of flow.
Repeater by the liquid and the pump wheel, the turbine blade interaction to produce changes in the momentum moment to pass the torque. While the turbine will be the oil kinetic energy and potential energy and turn into the output shaft of the mechanical energy, in order to achieve the flexible transmission of energy. The rotating housing is connected to the pump wheel, and a radially displaceable spoon tube is placed in the rotating housing. During operation, the oil in the chamber rotates with the same rotation speed of the pump wheel as the rotating housing, and the oil ring rotates at a peripheral speed Fixed does not turn (can only move) of the emerald filter guide tube, the head end of the mouth, the kinetic energy becomes a bit of energy, oil ring oil from the diversion tube outflow.
Repeater overload, the oil temperature and pressure increased sharply, the rubber seal quickly aging, sealing performance deterioration, oil leakage to reduce the torque, resulting in starting difficulties. Conveyor reducer bevel gear shaft is connected with the relay, the structure is irrational, heavy, easy to install and handling the process of bending caused by bending deformation; factory only for static balance Test, in the high-speed operation, due to unbalanced additional load and shaft vibration, so that the working state of the shaft deteriorated. When the Repeater is started, the force and stress of the shaft are deteriorated, resulting in spline deformation. After the use of Repeater, there will still be burned motor accident, mainly the lack of understanding of the performance of equipment and the use of incorrectly caused; the input characteristics of the Repeater to determine the motor operating conditions, in the i = 0 workers When the operation is running, the oil in the Repeater must be vented to prevent the motor from being overloaded for a long time.
The transmission efficiency of the Repeater is equal to the output shaft speed multiplied by the output torque (output power) multiplied by the input shaft speed by the input torque (input power). The output torque is equal to the input torque minus the friction torque, so its output torque is always less than the input torque. The relay input shaft and the output shaft are connected with the liquid, and there is no rigid connection between the working members. General Repeater normal operating speed ratio of 0.95 or more can get a higher efficiency. Repeater Pike filter characteristics due to the working chamber and the pump wheel, the turbine shape is different. If the relay of the oil vent, the coupler is in a disengaged state, can play the role of clutch. After the pump wheel and the turbine are assembled, an annular cavity is formed which is filled with working fluid. Pump wheel is usually in the internal combustion engine or motor drive under the rotation, driving the working fluid to do more complex centripetal force movement. Can, oil ring oil from the diversion pipe outflow.
