DresdenHydraulWhen using hydraulic elevators, frequent inspections and maintenance should be carried out, but also enables it to exert greater power during operation. Of course, hydraulic elevators also have their own regular repair times and protection methods: regular protection (carried out per shift).
Motor not running: Check all components of the motor for damage and check if there are any problems with the circuit and wiring.
Dresden.Check valve leakage oil pipe check valve leakage. The solution is to carefully check whether the one-way valve is functioning properly. If it is not normal, it is recommended to replace the one-way valve with a new one.
The hydraulic lifting platform often checks the connection status of each part, and if there is any looseness it should be tightened. The connection bolts of the machine body should be checked for tightness when the elevator body is under pressure (the compression condition can be formed by rotating the arm). All connecting shafts need to have split pins and need to be fully opened.
.When using hydraulic elevators, the main causes of noise are mechanical mechanism failures, hydraulic system failures, electrical equipment or component failures, etc. Today, the manufacturer of hydraulic cargo elevators will introduce to you the reasons for the noise generated by hydraulic elevators.
Volume speed control circuit: Speed control is achieved by adjusting the displacement of a variable pump or variable motor.
Oil leakage from the oil cylinder: If it is a problem with the sealing ring, it is recommended to replace it with a new one.
The electromagnetic coil of the electromagnetic directional valve is not firmly fixed,DresdenAluminum alloy hydraulic lifting platform, and frequent separation and suction can also produce high noise.
Hydraulic oil deteriorates or produces impurities. After long-term use of oil pressure, there may be impurities or deterioration in the oil. Sampling inspection should be carried out to see if there are solid particles, discoloration, the oil should be changed. There may be blockage in the hydraulic pipeline of the hydraulic cargo elevator. The hydraulic pipeline is also a very important part, and it is necessary to check whether the hydraulic pipeline is smooth. Focus on checking whether each type of hydraulic valve includes one-way globe valve, electromagnetic directional valve, proportional control valve, overflow valve, etc. If there are problems the hydraulic valve should be cleaned or replaced in a timely manner.
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, becoming a better choice for some high-altitude operations. However, there are still certain limitations, such as height and improving the quality of goods, which have certain constraints.
Safety production.The lifting platform is a multifunctional heavy loading and unloading mechanical equipment, which can be divided into fixed and mobile, guide rail and curved arm types. Fixed types include scissor elevators, chain elevators, loading and unloading platforms, and attached electric construction platforms.
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.
The manufacturer of the hydraulic cargo elevator tells you the reason and cleaning method: Reason: Overload cleaning method: Reduce the load to clean. Reason: The return valve is not closed. Cleaning method: Tighten the return valve to clean. Reason: The one-way valve of the manual pump is stuck and the return valve is malfunctioning. Cleaning method: Unscrew the bolt at the valve port of the oil pump, conduct maintenance, cleaning, and replace the cleaning hydraulic oil to clean.
Before installation, the installation personnel should confirm the infrastructure such as the foundation and shaft pay attention to alignment, leveling, and alignment points, and confirm that the foundation meets the requirements before construction.
Meticulous workmanship.The 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, Mixing air into the oil to eliminate: The concentricity should be adjusted to within 0.1MM. The coupling should be repaired or the oil pump should be replaced to increase the oil volume above 400mm in the oil filter and joint positions. The rotating shaft sealing ring should be replaced to clean the oil filter screen, 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.
The hydraulic system of the fixed lifting platform of the hydraulic cargo elevator is equipped with anti fall and overload safety protection devices,DresdenGuide rail hydraulic lifting platform,DresdenFixed hydraulic lifting platform, and operation buttons can be set on each floor and the lifting platform workbench to achieve multi-point operation.
The main device does not engage. When this fault occurs, whether the internal and external emergency stop button switches, the electric lock switch are turned on, whether the three-phase electrical phase sequence is correct, and whether the relay working indicator light is on.
Dresden.Separate: Loading and unloading on different platforms.
The hydraulic lifting platform often checks the connection status of each part, and if there is any looseness, it should be tightened. The connection bolts of the machine body should be checked for tightness when the elevator body is under pressure (the compression condition can be formed by rotating the arm). All connecting shafts need to have split pins and need to be fully opened.
Hydraulic elevator manufacturers remind us that the basic principle of the hydraulic elevator speed control circuit is that the system often needs to adjust the movement speed of the hydraulic cylinder and hydraulic motor to adapt to the working cycle needs of the main machine. The speed of hydraulic cylinders and hydraulic motors depends on the displacement and input flow rate. It can be seen that changing the flow rate or displacement can affect the speed of the cylinder and motor.
