OsnablukScissoReason: The lowering speed valve is out of adjustment. Cleaning method: If the lowering speed valve is adjusted, replace it with a new valve.
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, new steel wire ropes will not suddenly break when used under normal circumstances, unless incorrect operation or safety protection devices fail, as the load borne by the steel wire may exceed its breaking capacity. The damage to the steel wire rope of the cargo elevator is mainly gradually formed during long-term use. After a certain period of repeated bending and friction,OsnablukLifting table hydraulic pressure, the steel wire on the surface of the steel wire rope will experience bending fatigue and wear, and the steel wire on the surface layer will gradually break. At this point, if it cannot be used again, it should be replaced in a timely manner to ensure the safety of the hydraulic platform.
After 1500 hours of elevator operation, perform minor repairs to the mechanical and electrical systems.
.Surface paint quality: The paint should be smooth and flat have good adhesion with metal,OsnablukImported hydraulic lifting platform, have uniform color, no bubbles, no cracks, and there should be no wrinkles, pits, paint leakage, and sagging.
Separate: Loading and unloading on different platforms.
Pay attention to checking each steel wire rope for signs of broken wires and loose drums. If it exceeds the relevant rules, it is necessary to replace it immediately. The protection of steel wire ropes should strictly follow the rules of GB5144-85.
When the hydraulic oil is insufficient, the hydraulic pump will experience suction, causing air to enter the hydraulic oil and producing high noise.
In case of strong wind of level 6 or above, rainstorm, thunder, fog and other bad weather, the work at heights in the open air shall be stopped at the boarding bridge.
If the circuit of the device is not disconnected or lowered, it is necessary to check the fuse for repair and replacement.
How many?.The manufacturer of hydraulic cargo elevators reminds the use of guide rail hydraulic lifting cargo elevators. Guide rail hydraulic lifting cargo elevators: Do not stand within the specified range, draw on the guide rail lifting platform, ensure that the work area is free of clothing, and maintain a clean and tidy workplace.
The characteristics of the platform include reliable hydraulic system, simple operation, large load-bearing capacity, and rear hinge support.
Regularly check all wires and cables for damage. It is necessary to wrap and replace the damaged parts in a timely manner.
The electromagnetic coil of the electromagnetic directional valve is not firmly fixed, and frequent separation and suction can also produce high noise.
Discount.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 it is easy to cause the pilot valve performance of the overflow valve to be partially stable, 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 should be replaced.
What are the benefits of hydraulic cargo elevators compared to traditional elevator cargo transportation?
Ensure that there is a suitable power supply at the installation site, and separate maintenance of the distribution box is required. The distribution box should have a leakage switch, it should be suitable for the operating power.
Osnabluk. 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,OsnablukIndoor fixed hydraulic lifting platform, and resonance occurs with components in the circuit. Troubleshooting: Strengthen sealing, repeatedly adjust the pressure, exhaust and clean the valve body several times Make the damping hole unobstructed, 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.
An inverter can also generate high noise. When the power supply voltage is lower than 85% of the rated voltage 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.
The undercut length of the weld mm should not exceed 10% of the weld seam, and the depth should not exceed 0.4mm.
