Las VegasProduThe above are the working principles of three common elevators, and there are also some forms of elevators that are not common, such as cylinder mounted elevators, curved arm elevators, car mounted elevators, etc. Their common feature is the hydraulic principle for operation, because the stability of the hydraulic system can bring better user experience and safer operation to the equipment, which has been favored by many users.
Reason: The lowering speed valve is out of adjustment. Cleaning method: If the lowering speed valve is adjusted, and if the adjustment is ineffective, replace it with a new valve.
Las Vegas.The so-called input hydraulic energy refers to the input flow rate and pressure, and the output machinery is the speed and traction force during linear motion. All these parameters are achieved through changes in working volume, so hydraulic cylinders are a type of volumetric actuator. In order to meet the different needs of various machinery, hydraulic cylinders have different structures and hydraulic capabilities. According to hydraulic capacity, it can be divided into single acting hydraulic cylinders and double acting hydraulic cylinders. According to its structural characteristics it can be divided into plunger hydraulic cylinders and hydraulic cylinders. Telescopic hydraulic cylinders and hydraulic cylinders are both referred to as the heart of hydraulic cargo elevators. How to maintain the heart of a hydraulic cargo elevator? Professional elevator manufacturers guarantee quality, service,Las VegasFixed hydraulic lifting platform,Las VegasManual pressure relief of hydraulic lifting platform, the short circuit ring of the iron core of the device breaks, the surface of the magnetic yoke and armature is skewed, dust or rust is poor, and the device will produce; Buzz&# quo; Noise.
. There is air in front of the pilot valve of the elevator overflow valve noise overflow valve. The damping hole on the main valve core of the overflow valve is blocked by oil dirt, and the pilot valve and valve seat are matched without spring deformation or incorrect installation. The remote control port has excessive oil flow, low or high hydraulic oil viscosity, and resonance occurs with components in the circuit. Troubleshooting: Strengthen sealing, repeatedly adjust the pressure, exhaust and clean the valve body several times, repair or replace the spring, reduce the flow of the remote control port, replace the oil, and other components. The pressure setting of other components should not be similar to the pressure setting of the relief valve. 5. The noise of the elevator pipeline is usually caused by excessive dead bends or loose fixed sleeves in the hydraulic pipeline.
Lifting mechanism: The workbench should be ensured to rise and fall smoothly, and there should be no jumping lifting phenomenon. All moving parts should be flexible when moving and there should be no jamming devices. The lifting system of the elevator is divided into electric or manual hydraulic systems, and there should be no leakage at all components, pipelines, and joints.
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, if possible, please use safety protection measures

Based on the foundation plan, pay attention to alignment, leveling, and alignment to ensure the foundation level and various usage requirements. The access road for external construction elevators should be flat and have sufficient space for equipment parking.
The lifting platform is placed on a horizontal support surface,Las VegasMast type aluminum alloy hydraulic lifting platform, and the concentrated load of MAX load capacity is placed at any position 300mm away from the periphery of the workbench. After lifting 100 times each load-bearing component must not have deformation or cracks.
system.The hydraulic oil used in the system has the same brand, and the oil temperature is between 45~80 ℃. Use a large flow rate to remove impurities from the system as much as possible. The hydraulic system needs to be cleaned repeatedly three times or more, and after each cleaning, the system should be drained while the oil is hot. After cleaning, clean the filter and add new oil after using a new filter element.
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.
The combined platform is often used in small workshops with small volume of goods. However, because this platform needs to complete two functions at the same time, it inevitably increases the distance of handling tools/vehicles in the workshop.
Considering the oil level in the oil tank, when all hydraulic cylinders in the system are extended, the oil level in the oil tank should not be lower than the Z-low oil level, and when the oil cylinders retract, most manufacturers have noticed the above issues. The reason for the introduction is that most users can learn more about the equipment itself when using elevators, in order to facilitate equipment maintenance. Hydraulic cargo elevator manufacturers sincerely hope that you choose a legitimate manufacturer when purchasing elevators, to avoid any worries about after-sales service.
Development Curriculum.A hydraulic elevator is a type of elevator equipment consisting of a walking mechanism, hydraulic mechanism, electric mechanism, and support mechanism. The hydraulic oil forms a certain pressure by the vane pump, and enters the lower end of the hydraulic cylinder through an oil filter, explosion-proof electromagnetic directional valve, throttle valve, hydraulic control one-way valve, causing the hydraulic cylinder to move upwards and lift heavy objects. The return oil at the upper end of the hydraulic cylinder returns to the oil tank through the explosion-proof electromagnetic directional valve, and its rated pressure overflow valve is adjusted. The pressure gauge observes the reading value on the pressure gauge.
When working at heights, except for relevant personnel, no one is allowed to walk or stay below the workplace. Fencing or other protective devices should be installed below the workplace to prevent falling objects from injuring people.
The smoothness of the gearbox, gearbox, external meshing gears, and hydraulic oil are all carried out according to the requirements in the smoothness table.
Las Vegas.After 10000 hours of operation on the hydraulic lift, major repairs will be carried out to the mechanical and electrical systems.
Reason: Manual pump and gear pump have severe oil leakage. Cleaning method: Replace the oil pump sealing ring to clean it. Reason: Gear pump is damaged, The oil pumped out has no pressure. Cleaning method: Replace the gear pump to clean the problem. Reason: Lack of hydraulic oil. Cleaning method: Add enough hydraulic oil to clean the problem. Reason: Circuit open. Cleaning method: Check the button and fuse to clean the problem. Reason: Filter blockage. Cleaning method: Replace or clean the problem. Reason: Support valve or electromagnetic directional valve malfunction. There are two situations: the input voltage of the electromagnetic coil is lack of 220V. The solenoid coil is burnt out and the valve core is stuck. Cleaning method: maintenance or replacement can be used to clean the natural descent of the lifting platform. Reason and cleaning method: one-way valve leakage cleaning method: check the check valve in the valve. Assuming there is dirt on the sealing surface of the check valve. Clean the check valve.
The undercut length of the weld mm should not exceed 10% of the weld seam, and the depth should not exceed 0.4mm.
