PwotskFixed hydraulic lifting platformWhat are the main control systems described

The hydraulic lifting platform often checks the connection status of each part, 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.

Electrical equipment or component failures. Hydraulic elevator manufacturers tell you that the main reasons for high noise generated by electric motors are: bent or severely worn motor rotors, or damaged bearings, which cause electric motors to sweep and produce noise; The cooling fan of the electric motor is damaged or not firmly fixed, resulting in high noise; The electric motor is not firmly fixed and can also cause vibration, producing high noise.

Pwotsk.This product has a solid structure, high load-bearing capacity, smooth lifting, easy installation and maintenance and is an ideal cargo transportation equipment for replacing elevators on lower floors.

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

.The main device does not engage. When this fault occurs, check whether the three-phase power supply is normal, 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.

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, 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.

Hydraulic lift cargo elevators belong to high-altitude work equipment. Small shaking of the scissor type structure is normal, but excessive deviation is a symptom. It is necessary to find the cause and make correct judgments in a timely manner. Generally speaking, operations above 8 meters are generally allowed. Due to its own weight, devices above this height begin to vibrate in different ranges. The vibration range depends on factors such as weight, lifting height, and intensity of high-altitude operations.

The installation personnel should confirm and count the equipment details, confirm that there are no omissions in the shipped equipment details, check if the tools are complete, and ensure the smooth progress of the installation process.

Safety advantages: Hydraulic elevators are equipped with the safety devices of traditional traction elevators: overflow valve: it can prevent system pressure from being too high when going up; Emergency manual valve: In case of power failure,PwotskLifting hydraulic platform, it can cause the car to emergency descend to the nearest floor position, causing the car to emergency descend to the nearest floor position, and causing the emergency in the car to descend to the nearest floor position; Pipeline rupture valve: When the hydraulic system's pipeline ruptures and the car stalls and descends, it can automatically cut off the oil circuit and stop descending; Oil temperature protection of oil tanks: When the oil temperature of the oil tank exceeds the standard setting value, the oil temperature protection device sends a signal to stop the use of the elevator and wait for the oil temperature to decrease before starting the elevator. Long term promotion of downgrading manufacturers, 20 year old brand, with price advantages and guaranteed quality!

Set up warning lights around the guide rail type hydraulic cargo elevator equipment, and the warning lights will light up to warn operators when loading and unloading materials. Idle personnel are prohibited from entering the operating range.

Application process.After 5000 hours of elevator operation, carry out medium maintenance on the mechanical and electrical systems.

The downward movement of the hydraulic cylinder (i.e. lowering of heavy objects). 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. To ensure a smooth descent of heavy objects and safe and reliable braking, a balance valve is installed on the return oil circuit to balance the circuit and maintain pressure, so that the descent speed does not change due to heavy objects. The throttle valve regulates the flow rate and the ascending and descending speed. To ensure safe and reliable braking and prevent accidents, a hydraulic control one-way valve, is added to ensure safe self-locking in the event of an accidental rupture of the hydraulic pipeline. An overload sound control alarm has been installed to distinguish between overload or equipment failure.

Oil leakage from the oil cylinder: If it is a problem with the sealing ring, replace the sealing ring. If there are debris or debris on the oil cylinder, it is recommended to replace it with a new one.

The precautions to consider when selecting a hydraulic lift oil tank include: considering the structure of the oil tank the partition in the traditional oil tank cannot settle dirt. 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.

Quality management.Regularly check all wires and cables for damage. It is necessary to wrap and replace the damaged parts in a timely manner.

When using a crane for auxiliary installation, full consideration should be given to whether the on-site environment meets the operating conditions of the crane.

Regularly check all wires and cables for damage. It is necessary to wrap and replace the damaged parts in a timely manner.

Pwotsk.Vehicle mounted lifting platform is widely used for high-altitude operations in hotels,PwotskFreight elevator type hydraulic lifting platform, buildings, airports, sports venues, workshops, warehouses, and other places; It can also be used as temporary high-altitude lighting, advertising,PwotskHydraulic lifting platform lifting cargo elevator, etc.

The contact of the travel switch must be firmly opened and closed, and the contact crater should be polished in a timely manner.

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.
