Angola hydraulic cylinder,sanitation truck hydraulic cylinder manufacturer,sanitation truck hydraulic cylinder(Angola sanitation truck hydraulic cylinder,produced by Hengyu Hydraulic Cylinder Factory)
sanitation truck hydraulic cylinder are widely used in Angola,because of smooth movement,high work efficiency,excellent fatigue and impact resistance.So our company has designed sanitation truck hydraulic cylinder for customers from Angola.
The assembly work of the sanitation truck hydraulic cylinder has a great impact on the quality of the sanitation truck hydraulic cylinder: each part must be carefully cleaned before assembly; To correctly install the sealing device everywhere: when installing the sealing ring, pay attention to its installation direction to avoid oil leakage due to installation, and its lip should be equipped with a pressure oil chamber. In addition, because it is a YX-shaped sealing ring, it is necessary to pay attention to distinguish between shaft and hole use, do not install wrong; Because the sealing device is matched with the sliding surface, an appropriate amount of hydraulic oil should be applied during assembly; The special wrench should be used when the threaded coupling is tightened, and the torque should meet the standard requirements; After the piston and piston rod are assembled, it is necessary to measure whether the coaxiality and straightness on the full length are out of whack. After assembly, there should be no blocking sensation and uneven resistance when the piston assembly moves.
The sanitation truck hydraulic cylinder is mainly composed of body, piston, piston rod, sanitation truck hydraulic cylinder head, sanitation truck hydraulic cylinder bottom, piston rod head and related auxiliary devices. The piston divides the sanitation truck hydraulic cylinder into two chambers, and moves reciprocally in the sanitation truck hydraulic cylinder with the help of pressure oil. In order to improve its working effect, there is no sealing ring on the piston to eliminate internal leakage, where the piston rod passes through the sanitation truck hydraulic cylinder head, due to the existence of the gap, it is easy to produce external leakage phenomenon, and the dust can enter the sanitation truck hydraulic cylinder through the gap, so the sealing device and dust prevention reason are set. At the same time, in order to eliminate the influence of eccentric load on the work of the piston, all the sanitation truck hydraulic cylinders must be provided with a considerable length of guide sleeve at the extended end of the piston rod. In addition, in the case of faster piston movement, the phenomenon of mechanical collision between the piston and the sanitation truck hydraulic cylinder bottom and the sanitation truck hydraulic cylinder head is serious, so the buffer deceleration should be set at both ends of the sanitation truck hydraulic cylinder The working medium of the sanitation truck hydraulic cylinder: because it works at room temperature, the ordinary oil-type hydraulic oil can be selected; sanitation truck hydraulic cylinder sealing device: The use of Yx sealing ring, polyurethane (PU) and polytetrafluoroethylene (PTFE) materials combined to achieve a good sealing effect; Buffer mechanism of the sanitation truck hydraulic cylinder: The buffer structure of the sanitation truck hydraulic cylinder is to prevent the piston from colliding with the sanitation truck hydraulic cylinder head at the end of the stroke.
In use, the sanitation truck hydraulic cylinder should try to avoid the friction iron powder or iron filings formed by buffering the plunger. When the matching gap of the buffer device is small and the transverse load on the piston rod is large, the sintering phenomenon may be caused. These friction iron powder or the metal fragments that have fallen off as a result of sintering will remain in the sanitation truck hydraulic cylinder.
sanitation truck hydraulic cylinder abnormal sound, hysteresis phenomenon cause and elimination method: the piston rod is extended with abnormal sound and hysteresis, if the sanitation truck hydraulic cylinder is placed for a period of time, the sanitation truck hydraulic cylinder may enter the air, and the movement can be normal after dozens of repeated movements. If it still cannot be eliminated, check whether the load is aligned with the axis of the piston rod; Retracted piston rod installation helps to align the load with the piston rod. If the flow is unstable, it will also lead to abnormal movement of the piston rod. Check the relevant components of the hydraulic system.
The inner diameter of the injection cylinder is 203.2mm and the diameter of the screw is 63.5mm. What is the enhancement ratio?
Oil pressure multiplied by the cross-sectional area of the cylinder is equal to the theoretical output force value, and then multiplied by the efficiency of the cylinder is equal to the actual output force value, and the oil pressure can be calculated by inverting the value input.
What is the problem that the cylinder stroke is not in place?
1. Mechanical cause: the piston rod bends; If there is a synchronous cylinder, the stroke of the two cylinders may be different. 2. Hydraulic reason: the system back pressure is too large; The actuator load increases while the system pressure decreases. The electric is not sent, the reversing valve is not reset or stuck, the oil is too dirty, there is gas in the system, the external inertia load is too large, and the cylinder stroke is not in place.
