At present, in the hydraulic system of construction machinery, the commonly used oil change method is by cycle or by train number. The hydraulic system of some construction machinery requires that the hydraulic oil be replaced when the motorcycle is 1200. surface want to buy Cycloidal motor of overhead crane Grid 6 has reference value. For the maintenance of the hydraulic system, the parameters in Table 7 of the used hydraulic oil can better explain the problem. If the three items in Table 7 generally exceed the limit, the hydraulic oil shall be replaced. Except that the solid particles exceed the limit, that is, the hydraulic oil shall be replaced if the solid particles exceed the limit. During field inspection of oil, empirical inspection shall be carried out first, and whether to continue quantitative inspection shall be determined according to the observed oil pollution. According to the test results, determine the solution Cycloidal motor of overhead crane Price What measures shall be taken for oil pressure (half oil change, full oil change or filtration). Thus, the quality of hydraulic oil in the hydraulic system can be guaranteed, so as to reduce system failures and improve the reliability of the system.
Of course, you can increase the traffic want to buy Cycloidal motor of overhead crane Increase the speed, but how much will affect the service life. As long as it is within the rated power range, there is no problem. If the oil pressure reaches the rated pressure and the speed increases, it will exceed the power range it can withstand. Of course, it will damage the service life of the cycloidal hydraulic motor. Just like not eating so much hard food, it will damage the stomach. Increasing the flow can only increase the speed in a limited way, from 500 to 900, change the model of the motor, increase the flow of the cycloidal motor, increase the speed without control, increase the internal oil pressure, increase the internal leakage, directly reduce the efficiency, and damage the motor. Above Huzhou Price Ming can try, and consult the cycloid hydraulic motor expert if he thinks the error is found.
Cycloidal hydraulic motor structure: the internal meshing gear pair consisting of rotor and stator, cycloidal needle wheel, as the meshing pair, has a torque generating part. The stator, together with the spacer and the rear cover, is fixed on the housing to form seven cavities that are only connected with the oil holes on the housing one by one. A distribution mechanism consisting of an oil distribution sleeve and a housing. Two oil distribution sleeves Huzhou Cycloidal motor of overhead crane The ring groove is respectively connected with the oil inlet and return ports of the housing, and its longitudinal groove has twelve oil ports, Cycloidal motor of overhead crane Price Six oil ports and the oil distribution hole of the housing form the oil distribution link. The splines at both ends of the linkage shaft are respectively connected with the rotor and the output shaft, which is used to transmit torque and ensure that the oil sleeve is synchronized with the output shaft. The function of the output shaft is to output the torque generated by the rotor through the linkage shaft and drive the oil distribution device to rotate synchronously.
The output pressure of the hydraulic motor also depends on the load. Rated pressure Pn: the rated pressure refers to the working pressure that the hydraulic motor can withstand during continuous operation. It can want to buy Cycloidal motor of overhead crane To ensure the volumetric efficiency and service life of the hydraulic motor. Working pressure P: the working pressure is the actual pressure of oil input when the hydraulic motor is working Cycloidal motor of overhead crane Price power. Its value depends on the size of the load. However, the maximum working pressure is determined by the safety valve in the hydraulic system. The throttle adjustment value must not exceed the maximum pressure value of the hydraulic motor. The third is the maximum pressure: the limit pressure that the motor is allowed to overload in a short time. Pn ≤ Pmax value.
During the operation of hydraulic transmission, the hydraulic actuator can be adjusted steplessly in a large range by adjusting the control valve, and the speed range can reach 2000 meters. Good operation ability and rapidity. The liquid is elastic and can absorb impact, so the hydraulic transmission movement is even and stable; It is easy to realize fast starting, braking and frequent reversing. Reciprocating rotation want to buy Cycloidal motor of overhead crane The reversing frequency of rotary motion can reach 500 times/minute, and the reciprocating linear motion can reach 1000 times/minute. It is easy to control operation and realize overload protection. The hydraulic system with convenient operation and control is convenient for automatic control, remote control and overload protection; Automatic lubrication during operation, which is beneficial to Huzhou Price Heat dissipation, prolong service life. It is convenient for automation and electromechanical hydraulic integration. Hydraulic technology is easy to combine with electric control and electric control technology to form an electromechanical hydraulic integration composite system to realize automatic cycle work.
Along the revolution direction of the rotor, the volume of the tooth cavity at the front side of the connection between the rotor and the stator becomes smaller, which is an oil discharge cavity, and the volume at the rear side becomes larger. When the connecting line passes through the two tooth roots of the rotor, the oil inlet ends and the largest tooth cavity appears. When the connecting line passes through the two tooth tops of the rotor, the oil drainage ends and the smallest tooth cavity appears. In order to ensure the continuous rotation of the rotor, it is necessary to have the same regular oil distribution mechanism to cooperate with it, so that the tooth cavity at the front side of the connecting pipeline is always connected with the oil drain port, and the rear side is connected with the oil inlet port. As mentioned above, the oil distribution mechanism consists of a housing and an oil distribution sleeve. The 12 longitudinal grooves (x) on the oil distribution sleeve and the 12 intervals formed by the oil distribution groove face the root and top of the rotor through the positioning device, which proves that when the largest and smallest cavities occur, the oil distribution hole of the housing can be closed, thus separating the oil inlet groove and oil outlet groove of the oil distribution sleeve.
