As a hydraulic equipment, hydraulic motor has been widely used in many factories. Generally, we should master the assembly skills of the hydraulic motor: the hydraulic system should want to buy Crane cycloid motor Correct machining and assembly. The mounting surface of the hydraulic valve on the oil block should be straight, and the sealing surface of the sealing groove should be finished to avoid radial scratches. The preload of the connection between the hydraulic valve and the oil circuit block and the connection between the oil circuit blocks shall be sufficient to prevent surface separation. The hydraulic equipment shall be inspected according to relevant standards before assembly Crane cycloid motor manufactor Check the pressure leakage of system components. If problems are found, corresponding measures shall be taken. If the problem is serious, it should be replaced. Accurately formulate the assembly process documents of hydraulic equipment, configure necessary assembly tools, and strictly follow the assembly process. Keep the hydraulic components, accessories, sealing parts and pipe fittings clean to prevent contamination, and check the integrity of the sealing surface and connecting threads. The hydraulic connector should not be tightened too tightly, otherwise some parts will be severely deformed or even broken, causing leakage. Avoid damaging sealing parts during assembly.
The valve control system controls the flow by changing the opening of the valve throttle, thus controlling the speed of the actuator. Usually, the reason for low efficiency is the existence of throttling and overflow losses. Almost all mechanical equipment adopts valve control system. The pump control system can realize the stepless control of speed by changing the displacement of variable displacement pump, or control the flow through the combination of multiple constant displacement pumps to achieve the stepwise control of speed. The reason for high efficiency is that there is no throttling or overflow loss. It is widely used in high power hydraulic devices such as pressure processing machinery and plastic machinery. The actuator control system controls the flow by changing the variable hydraulic motor flow of the actuator, or through the joint work of multiple quantitative hydraulic motors, or by changing the action area of the composite hydraulic cylinder. Similar to the pump control system, this system has high efficiency because it has no throttling and overflow losses. It is suitable for traveling machinery, press and other hydraulic equipment.
When the high-pressure oil enters the oil distribution shaft and enters each plunger cylinder hole of the working section through the oil distribution window, the corresponding plunger set is pushed against the curved surface of the cam ring L (housing), Zhongshan Crane cycloid motor The cam ring surface gives a reaction force to the plunger at the contact position. This reaction force N acts on the common plane where the cam ring surface contacts the roller. This normal reaction force N can be decomposed into radial force PH and circumferential force T, which are balanced with the hydraulic pressure at the bottom of the plunger, while the circumferential force T overcomes the load torque, want to buy Crane cycloid motor Drive cylinder 2 to rotate. Under this working condition, the cam ring and oil distribution shaft do not rotate. At this time, the plunger corresponding to the oil return section of the cam gear moves in the opposite direction, and the oil is discharged through the oil distribution shaft.
Generally, rolling bearing or hydrostatic sliding bearing, hydraulic want to buy Crane cycloid motor Since the pressure motor works under the condition of input pressure oil, it does not need to have self-priming capacity, but it needs to have a certain initial air tightness to provide the necessary starting torque. The existence of these differences makes the structure of the hydraulic motor and the hydraulic pump relatively close, but they cannot work reversibly. The classification of hydraulic motors can be divided into gear type, impeller type, plunger type and other types according to the structure type. According to the rated speed of the hydraulic motor, it can be divided into high speed and low speed. The rated speed exceeds 500r/min Zhongshan Crane cycloid motor High speed hydraulic motor, while the rated speed is lower than 500r/min, it belongs to low speed hydraulic motor.
The radial piston hydraulic motor uses a cam ring with a special curve to make each plunger reciprocate several times within one cycle of cylinder block rotation, which is called multi action want to buy Crane cycloid motor Internal curve radial plunger hydraulic motor (referred to as internal curve motor) is used. The internal curve motor has the advantages of small size, light weight, radial force balance, small torque ripple, high starting efficiency, stable operation at very low speed, etc. It has been widely used Crane cycloid motor manufactor In marine machinery. Working principle of inner curve motor: the inner wall of the cam ring (housing) is composed of x evenly distributed curved surfaces with the same shape. Each curved surface with the same shape can be divided into two symmetrical sides. The side that allows the plunger set to extend outward is the working section (oil inlet section), and the opposite side is called the oil return section. The number of reciprocating times of each plunger per revolution of the hydraulic motor is equal to the number of curved surfaces of the cam ring x (x is called the number of times of action of the motor).
