Jersey Hydraul
Jersey HydraulThe noise and oil level of the elevator oil cylinder are too low. From the air at the connection of the oil filter or joint to the oil, the coupling inside the oil cylinder is loose. The internal fault of the oil cylinder is that the installation of the oil cylinder motor is not concentric. From the motor, the air and oil at the moving shaft are blocked. The oil return pipe of the oil filter is loose, and the air or oil pipe is on the oil surface, filter the oil, lock the return oil pipeline, and extend the return oil pipeline below the oil level. If there is air mixed in the oil or the air in the hydraulic cylinder is not completely discharged, it will cause cavitation under high pressure and cause significant noise. At this point, it is necessary to exhaust the air in a timely manner.
Road noise can also occur if tires are crushed against objects that are prone to noise. The shaking amplitude of the scissor type lifting platform is proportional to its lifting height. The higher the height, the greater the shaking. When using it at a working height of 10 meters, if possible, please use safety protection measures
Jersey .When maintaining hydraulic components, the workbench must be clean. The purpose of the inspection tool.
Pre install equipment, maintain unobstructed access roads and sufficient parking space before pre installation. Some hydraulic cargo elevators require heavy lifting assistance for installation, some require equipment such as forklifts for installation, and some can be pre installed manually. When it is necessary to install with the assistance of a truck crane and a forklift, full consideration should be given to whether the on-site environment meets the working conditions of the truck crane.
.After the pre installation is completed, the pre installed equipment should be fixed, and the positions of cables,Jersey Indoor hydraulic lifting platform, oil pipes, and components such as the pre installed frame should be confirmed to be correct before reinforcement work can be carried out. Reinforcement requires welding or screws, perform minor repairs to the mechanical and electrical systems.
Therefore, the wholesale manufacturers of hydraulic elevators remind that there are three main ways to adjust the speed control circuit: throttling speed control circuit: quantitative pump oil supply, using flow valves to adjust the flow in and out of the actuator to achieve speed control; In the volume throttling speed control circuit, the oil is supplied by the pressure limiting variable pump, and the flow rate into the actuator is adjusted by the flow valve to adapt the flow rate of the variable pump to the regulated flow rate of the speed control valve.
When encountering signs of overheating in the electric motor, it is necessary to park the car in a timely manner, clean the problem, and continue running. The motor bearings should be smooth and outstanding.
Therefore, the oil should be replaced regularly to ensure that the additives are effective. The filter can only absorb a limited amount of dirt particles and other impurities from the oil. Replace the filter according to the recommended cycle to keep the system clean.
Hydraulic cargo elevators have been used in some high-altitude operations in recent years, and now some hydraulic cargo elevators are gradually mentioned as large machinery such as tower cranes, there are still certain limitations such as height and improving the quality of goods, which have certain constraints.
Statistics.Stable and widely applicable cargo lifting equipment is mainly used for transporting goods between height differences in production lines; Material online and offline; Adjust the height of the workpiece during assembly; High altitude feeder feeding; Lifting of components during assembly of large equipment; Large machine material and cutting; The warehouse loading and unloading site is equipped with forklift and other transportation vehicles for rapid loading and unloading of goods.
The installation personnel should have the qualification for installing hydraulic cargo elevators, carefully implement the special construction plan for installation and construction, and provide safety technical disclosure to the installation personnel for technical design.
Stability: The workbench should evenly withstand 125% of the MAX load capacity and be stable at the MAX elevation.
The hydraulic elevator overflow valve can also generate high noise. When air is mixed in hydraulic oil, the overflow valve is stuck or severely worn, the spring of the overflow valve is fatigued and deformed, resulting in unstable pressure regulation of the overflow valve and the relief time of the overflow valve is too short, causing air to vibrate inside the pilot valve and generate noise. So we need to regularly clean the overflow valve. When the overflow valve is damaged or severely worn it is easy to cause the pilot valve performance of the overflow valve to be partially stable, it should be replaced.
details.New reference wiring diagram 2. Elevator leg noise. Mobile elevators should open the legs before operation. In this case, if the legs lack butter, noise will be generated.
Any work carried out at a height of 2 meters or above should be considered as work at height. Any work that can be done in advance on the ground must be done on the ground to minimize high-altitude operations.
Oil leakage is a common malfunction. Due to loose joints or damaged sealing rings, oil leakage may occur. Therefore, this fault can be solved by tightening the oil leakage joint or replacing the damaged sealing ring.
Jersey .The speed circuit is the circuit that switches the motion speed and speed of the actuator in the hydraulic system of the guide rail hydraulic lifting platform. Mainly including valves,Jersey Fixed hydraulic platform, pumps, and actuators. The commonly used speed circuits include speed circuits, high-speed circuits, and speed switching circuits.
The optional configurations of a fixed lifting platform include manual hydraulic power, rolling or motorized roller tracks, safety contact bars to prevent foot rolling, organ type safety protective covers, manual or motorized rotating workbenches, hydraulic overturning workbenches, safety support rods to prevent the lifting platform from falling, stainless steel safety nets, electric or hydraulic lifting platform walking power systems, and universal ball countertops.
Regularly check all wires and cables for damage. It is necessary to wrap and replace the damaged parts in a timely manner.
