A vertical partition should be installed along the longitudinal axis of the oil tank, with a space left between one end of the partition and the end plate of the oil tank to connect the gaps on both sides of the partition. The inlet and outlet of the hydraulic pump are arranged on both sides of the partition at the disconnected end, so that the distance Z between the inlet and return oil is far The hydraulic oil tank has more heat dissipation effect.
The use of cleaning oil and the brand used in the system
Mayday.When working on scaffolding without scaffolding or without railings, if the height exceeds 5 meters, safety belts must be used or other reliable safety measures must be taken.
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.
.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.
Therefore, 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.
Before installation, the installation personnel should confirm the infrastructure such as the foundation and shaft, pay attention to alignment, leveling, and alignment points, filter cover, inspection hole, hydraulic oil pipe and other parts to avoid dust when removing the system oil pipe. Clean the disassembled parts before opening them. When disassembling the hydraulic oil tank filler cap, first remove the soil around the tank cap, loosen the tank cap, and remove any remaining debris from the joint (do not rinse with water to prevent water from seeping into the tank). After confirming cleaning, open the tank cap.
The load of goods and the tonnage of goods transported at once also affect the lifting speed. The optimal value for transporting goods on a lifting platform is speed. If it is too heavy, and frequent separation and suction can also produce high noise.
Lets see. 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, 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.
Due to damage to the gear pump of the lifting cargo elevator equipment and no pressure lifting. Replace the gear pump.
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.
. The hydraulic oil enters the upper end of the hydraulic cylinder through the explosion-proof electromagnetic directional valve, and the return oil from the lower end of the hydraulic cylinder returns to the oil tank through the balance valve, hydraulic control one-way valve, throttle valve, and explosion-proof electromagnetic directional valve. In order to ensure a smooth descent of heavy objects and safe and reliable braking, a balance valve and balance circuit are installed on the return oil circuit to maintain pressure and ensure that the descent speed is not affected by changes in heavy objects. The throttle valve regulates the flow rate and the lifting speed. To ensure safe and reliable braking and prevent accidents a hydraulic one-way valve, also known as a hydraulic lock, is added to ensure safe self-locking when the hydraulic pipeline bursts. Install an overload sound alarm to distinguish between overload or equipment failure.

Therefore, maintaining the hydraulic cylinder is an important part of the entire hydraulic system maintenance. In addition, hydraulic cylinders are equivalent to the heart of the hydraulic system,MaydayHydraulic scissor type lifting platform, making it difficult to repair heart problems. Therefore,Maydayfork lifter, maintenance of hydraulic cylinders should be cautious. Professional elevator manufacturers have advanced technology, more affordable prices, and more discounts. Welcome to consult
Users should arrange dedicated personnel to operate hydraulic elevators, formulate usage details and safety precautions for hydraulic elevators based on their own situation, and hang them on the
Mayday.There is noise inside the hydraulic cylinder. When replacing the hydraulic oil, there was air in the hydraulic cylinder due to an operational error. Under high pressure, it is easy to generate cavitation and high-frequency noise. When the rod is bent or replaced with a new seal, which can also produce significant noise. If it is a problem of tight sealing, the noise can be reduced after running in for a period of time. If the rod is bent, it needs to be corrected. In addition, hydraulic pipelines should use hoses as much as possible, even when arranging pipelines, it can reduce vibration and noise, and the pipelines should avoid dead bends as much as possible.
When using hydraulic elevators, frequent inspections and maintenance should be carried out, which not only extends the service life of the hydraulic elevator, 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).
