What components mainly make up the hydraulic transmission part of the aluminum alloy cable tray pipe bender?
Power components: That is, the hydraulic pump, whose function is to convert mechanical energy into hydraulic energy and provide pressurized oil for the hydraulic system. Common types include gear pumps, vane pumps, and plunger pumps, etc. In the aluminum alloy cable tray pipe bender, the appropriate type of hydraulic pump is selected according to factors such as the system's pressure and flow requirements, as well as the working environment. For example, in situations where a higher pressure and relatively smaller flow are required, a plunger pump may be selected; while for cases where a larger flow and relatively lower pressure are needed, a gear pump or a vane pump is more suitable.
Actuating components: Mainly hydraulic cylinders, which are components that convert hydraulic energy into mechanical energy. They achieve the bending action of the aluminum alloy cable tray through the reciprocating motion of the piston. There are various structural forms of hydraulic cylinders, such as single-acting hydraulic cylinders and double-acting hydraulic cylinders, etc. In the pipe bender, the appropriate type and specification of the hydraulic cylinder are selected according to the requirements of the bending process and the structural layout of the equipment. For example, in some situations where a large bending force is required, a large-diameter double-acting hydraulic cylinder will be used to provide sufficient thrust and pulling force.
Control components: Including various valves, such as direction control valves, pressure control valves, and flow control valves.
Direction control valves: Mainly directional control valves, which are used to control the flow direction of the hydraulic oil, thereby changing the movement direction of the hydraulic cylinder and realizing actions such as the bending and resetting of the cable tray. Common directional control valves include solenoid directional control valves, manual directional control valves, and hydraulic directional control valves, etc. Different types of directional control valves are selected according to the automation level and operation requirements of the pipe bender. For example, in pipe benders with a high degree of automation, solenoid directional control valves are often used, and their spool movement is controlled by electrical signals to achieve fast and accurate directional change actions.
Pressure control valves: Such as relief valves, whose function is to limit the maximum pressure of the hydraulic system, prevent the system from overloading, and protect the safety of the equipment. At the same time, by adjusting the pressure setting value of the relief valve, the bending force of the pipe bender can also be adjusted. There are also pressure reducing valves, which are used to reduce the high-pressure oil in the system to the required low pressure and provide stable low-pressure oil for some components or circuits with lower pressure requirements.
Flow control valves: Such as throttle valves, flow control valves, etc., which are used to control the flow rate of the hydraulic oil, thereby adjusting the movement speed of the hydraulic cylinder and achieving the control of the bending speed of the cable tray. During the pipe bending process, according to the different material, specifications, and bending process requirements of the cable tray, the flow control valve is adjusted to precisely control the bending speed to ensure the bending quality.
Auxiliary components: Including oil tanks, oil filters, oil pipes, pipe joints, pressure gauges, etc.
Oil tanks: Used to store hydraulic oil and also play roles such as heat dissipation and sedimentation of impurities. The capacity of the oil tank is determined according to the flow rate and working requirements of the hydraulic system. Generally, it should ensure that the hydraulic oil can circulate in the system and has sufficient heat dissipation capacity.
Oil filters: Installed in the oil circuit of the hydraulic system, they are used to filter out impurities, particles, and other pollutants in the hydraulic oil, ensure the cleanliness of the hydraulic oil, prevent impurities from entering the hydraulic components, and cause component wear, blockage, and other faults, thereby improving the reliability and service life of the system.
Oil pipes and pipe joints: Used to connect each component in the hydraulic system and form a complete oil circuit channel. The material and specification of the oil pipes are selected according to factors such as the system's pressure, flow rate, and working environment. Common types include steel pipes, copper pipes, rubber pipes, etc. The pipe joints should ensure the tightness and reliability of the connection to prevent hydraulic oil leakage.
Pressure gauges: Used to display the working pressure of the hydraulic system. Operators can understand the pressure situation of the system by observing the reading of the pressure gauge, and promptly discover whether there are abnormal pressure changes in the system, so as to carry out adjustments and troubleshoot faults.
