HaHandmade chiThere are many reasons for unstable workbench descent, such as overload, unstable support,HaHydraulic mobile lifting platform, severe eccentric load, hydraulic oil impurities, etc. In response to the above reasons, it can be solved by reducing the load, adjusting the center of gravity of the load, and replacing hydraulic oil wholesale for hydraulic cargo elevators.
Each brush should be kept clean on its surface, and the brush pressure should be adjusted to ensure that its area is not less than 50%.
Ha.The size of the oil cylinder should be minimized as much as possible while meeting the design requirements. The smaller the diameter of the oil cylinder, the faster the lifting speed.
When the hydraulic system malfunctions, the hydraulic elevator may experience problems with the hydraulic pump, motor, valve, and hydraulic installation after repairing the hydraulic system, which can easily cause vibration and generate significant noise.
.The electromagnetic coil of the electromagnetic directional valve is not firmly fixed, and frequent separation and suction can also produce high noise.
The electromagnetic coil of the electromagnetic directional valve is not firmly fixed, and frequent separation and suction can also produce high noise.
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, also known as a hydraulic lock, 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.
When installing, disassembling, and adjusting the rotating mechanism, attention should be paid to ensuring that the middle line is parallel to the middle line of the gear and its meshing surface is not less than 70%. The meshing clearance should be suitable for the brakes of each mechanism. The clearance between the brake wheels should be regularly checked and adjusted to ensure its flexibility and reliability. There must be no dirt on the friction surface and it must be cleaned with gasoline or diluent.
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, 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!
The classification of lifting platforms is as follows: they are divided into mobile lifting platforms, automatic lifting platforms, folding arm lifting platforms, and sleeve type lifting platforms according to their different modes of movement.
technical service.A hydraulic elevator is a type of elevator equipment consisting of a walking mechanism, hydraulic 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,HaMicro hydraulic lifting platform, throttle valve, hydraulic control one-way valve, and balance 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.
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.
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.
When using hydraulic elevators the main causes of noise are mechanical mechanism failures, hydraulic system failures electrical equipment or component failures, the manufacturer of hydraulic cargo elevators will introduce to you the reasons for the noise generated by hydraulic elevators.
Convenient and efficient.When the hydraulic oil of the equipment is insufficient, it will not cause lifting. At this point, you only need to add enough hydraulic oil to run.
All high-altitude operations must first build scaffolding or take measures to prevent teams from falling before boarding the vehicle bridge.
When the hydraulic oil is insufficient, the hydraulic pump will experience suction,HaHydraulic lifting platform 18 meters, generally mobile equipment takes 2-3 times the high flow rate of pump Z, and fixed equipment takes 3-4 times.
The electromagnetic coil of the electromagnetic directional valve is not firmly fixed, and frequent separation and suction can also produce high noise.
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.
