Causes: 1. The pump is damaged, and the pump body is overheated and produces noise. 2. The control valve is closed tightly or the oil supply and return system is blocked, and local overheating occurs. 3. The safety valve is opened, and the valve cries or hisses, and local overheating occurs. 4. The distribution rotary valve is excessively leaking, and the valve chamber is overheated, and it is very hot when touched by hand. 5. The hydraulic motor crankcase is excessively leaking, and the single oil drain pipe is leaking special-purpose Danfoss cycloid motor Treatment method for excessive leakage and high oil level: 1. Check the condition of the ball joint 2. Check the sealing condition of the cylinder piston 3. Check the viscosity and operating temperature of the oil 4. Check the contact surface between the oil pan and the housing 5. Check the surface between the connecting rod and the eccentric wheel Danfoss cycloid motor Manufacturer 6. Check the wear of the oil pan and whether the two oil cavity channels at the inlet and outlet of the casting are connected

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 special-purpose Danfoss cycloid motor 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 Danfoss cycloid motor Manufacturer 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.

The hydraulic motor has two circuits: the hydraulic motor series circuit and the hydraulic motor braking circuit. These two circuits can be classified into the next category. One of the series circuits of hydraulic motors: three hydraulic motors are connected in series with each other, and a reversing valve is used to control the start stop and steering. The flow through the three motors is basically the same. When the displacement is the same, the speed of each motor is basically the same. The oil supply pressure of the hydraulic pump city in Guangxi Manufacturer High, small pump flow, generally used for light load and high speed. Serial circuit II of hydraulic motor: each reversing valve in this circuit controls one motor, each motor can work independently or simultaneously, and the rotation direction of each motor is also special-purpose Danfoss cycloid motor optional. The oil supply pressure of the hydraulic pump is the sum of the working pressure difference of each motor, which is applicable to the condition of high speed and small torque.

The ignition time of internal combustion engines can be compared with this. It can be seen from the working principle of the cycloidal hydraulic motor that the oil sleeve and the rotor rotate synchronously, and the accuracy refers to the accuracy of the oil distribution link matching with the rotor to rotate the oil inlet, seal and discharge. There are many factors special-purpose Danfoss cycloid motor It will affect the oil distribution accuracy, such as the asymmetry of the rotor spline and cycloid tooth shape, the relative position accuracy of the stator sleeve needle hole and bolt hole, and the relative position asymmetry of the pin hole and spline on the output shaft and its internal spline, Danfoss cycloid motor Manufacturer The relative position accuracy of the longitudinal oil groove and the relative wedge groove of the coupling, and the asymmetry of splines at both ends of the coupling. As long as the above factors are controlled within the tolerance range, they will not have a great impact on the oil distribution accuracy, because all processing errors will not be offset.
