The connection between the oil cylinder and the actuator and the connection between the oil cylinder and the oil pipe cannot be the same, because there must be some differences between the connection between the oil cylinder and different products. In addition, during the use of the oil cylinder, it is necessary to avoid scratches, Hohhot Hydraulic machinery Because if this problem occurs, it will affect the normal use of the oil cylinder. At present, there is no software for designing hydraulic cylinders, but there are design standards for hydraulic cylinders, and it is necessary to design hydraulic cylinders according to these standards. So far, Hohhot Hydraulic machinery Price There is no software for designing hydraulic cylinders, but there are design standards for hydraulic cylinders.
Before removing the hydraulic cylinder, depressurize the hydraulic circuit. Otherwise, when the oil pipe joint connected with the oil cylinder is loosened, Hohhot Hydraulic machinery The high-pressure oil in the circuit will be ejected rapidly. When the hydraulic circuit is depressurized, first loosen the hand wheel or pressure regulating screw at the overflow valve to unload the pressure oil, and then cut off the power supply or power source to stop the hydraulic device. During unloading, prevent damage to the thread at the top of the piston rod, the thread at the oil port, the surface of the piston rod, the inner wall of the cylinder liner, etc. Hohhot Hydraulic machinery Price In order to prevent the piston rod and other slender parts from bending or deformation, the skid shall be used to support and balance during placement.
There are many hydraulic components on construction machinery, and sufficient hydraulic oil is required. When the hydraulic oil needs to be replaced due to its deterioration after a long time of use, some people mistakenly believe that it is only necessary to drain the oil in the hydraulic cylinder Hohhot Hydraulic machinery Top up with new hydraulic oil. However, there are still many old hydraulic oils left in the hydraulic oil pipe and hydraulic control valve at this time. When the equipment is used, the mixing of new and old oils will speed up the deterioration of new oils. The correct oil change procedure should first drain the hydraulic oil in the hydraulic cylinder, clean the hydraulic cylinder, and then add new hydraulic oil, Hohhot Hydraulic machinery Price Then remove the circuit header, start the engine and run at low speed to make the oil pump work and operate each mechanism separately.
If the piston rod of the hydraulic cylinder is not treated in time after being pulled, the normal use will be affected if it is light, and the operation will not be possible if it is heavy. The repair methods we adopt are local polishing to repair light draw marks, welding and manual polishing to repair heavy draw marks. Hohhot Hydraulic machinery Through quenching and tempering treatment, the comprehensive mechanical properties of the cylinder piston rod with good strength and toughness matching were obtained. Hohhot Hydraulic machinery Price The purpose of surface hardening is to obtain high surface hardness to support the chromium plating layer on the surface, so as to improve the wear resistance and corrosion resistance of the piston rod.
1. There are many factors that cause this problem. First, measure the pressure of the main system to see whether the pressure of the main system in the pressure holding state is consistent with the initial setting. Check the hydraulic oil and suction oil filter before measuring the pressure, Hohhot Hydraulic machinery Replace or clean it. Secondly, check the main overflow valve of the reversing control multi way valve to see if it is damaged or blocked by foreign matters, Hohhot Hydraulic machinery Price Clean it. If your pump is a gear pump, the problem should be minor in general. 2. Next, let's look at the traffic problem.
It is suitable for hydraulic transmission of construction machinery, lifting, transportation machinery and mining machinery. Hydraulic transmission principle - oil is used as working medium, Hohhot Hydraulic machinery The movement is transmitted through the change of sealing volume, and the power is transmitted through the pressure inside the oil. 1. Power part - converts mechanical energy of prime mover into pressure energy (hydraulic energy) of oil. For example: hydraulic pump. 2. Executive part - converts the oil pressure energy input by the hydraulic pump into the mechanical energy driving the working mechanism. For example: hydraulic cylinder, hydraulic motor. 3. Control part - used to control and adjust the oil pressure Hohhot Hydraulic machinery Price Flow rate and flow direction. For example: pressure control valve, flow control valve.
