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, 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.
Larosh on the Yonghe River.When loading and unloading goods at the dock, hydraulic cargo elevators are often used. What are the advantages and disadvantages of hydraulic cargo elevators compared to electric cargo elevators?
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,Larosh on the Yonghe RiverHydraulic lifting platform, 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, 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.
.Remove the hydraulic oil tank filler cap, 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.
There is a phenomenon of self stopping when running up and down. Due to poor contact of the safety protection switch, it is easy for hydraulic cargo elevator manufacturers to cause this problem.
When the hydraulic oil is insufficient, the hydraulic pump will experience suction, causing air to enter the hydraulic oil and producing high noise.
Introduction to the unloading lifting platform: The unloading lifting platform is a specialized auxiliary equipment used in conjunction with forklifts for cargo loading and unloading. With it, forklifts can directly drive from the ground into the interior of car compartments for batch loading and unloading operations. The warehouse unloading platform products use manual hydraulic power and do not require power supply. Only one person needs to operate to achieve safe and fast loading and unloading of goods. It can reduce a lot of labor, improve the efficiency of loading and unloading operations, speed up the flow of materials, and obtain greater economic benefits.
Firstly, rust prevention is necessary. Because the part of the hydraulic cylinder needs to extend out of the cylinder during operation, it will naturally be corroded by oxides and acidic gases. This requires us to apply an appropriate amount of grease to protect it from erosion as a weight component. If we change the oil, we must open the box and use it for a long time to prevent the hydraulic cylinder from being used for a long time. In the operation of hydraulic cylinders, the speed should be appropriate and should not exceed 2m/s to extend the service life of the hydraulic cylinder. In addition, in order to protect the mechanism and safety, it is very important to install buffer devices internally to protect the hydraulic cylinder. The greater the pressure of the protective hydraulic cylinder, the heavier the load, and the greater its pressure. A specialized product manufacturing enterprise that integrates research and development, as well as service. A long-term professional elevator manufacturer
The use of cleaning oil and the brand used in the system
Sampling inspection.After 5000 hours of elevator operation, carry out medium maintenance on the mechanical and electrical systems.
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.
There is a phenomenon of self stopping when running up and down. Due to poor contact of the safety protection switch, it is easy for hydraulic cargo elevator manufacturers to cause this problem.
Ensure that there is a suitable power supply at the installation site, and the hydraulic cargo elevator construction site should be equipped with a fire extinguisher to prevent welding operations from causing fires. When selecting a leakage switch, it should be suitable for the operating power.
recommend.When encountering signs of overheating in the electric motor, it is necessary to park the car in a timely manner, clean the problem, a tight and firm protective partition, canopy or other isolation facilities must be erected in the middle of the boarding bridge, and workers must wear safety helmets.
When using hydraulic elevators, frequent inspections and maintenance should be carried out, 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).
Larosh on the Yonghe River.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%.
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.
If the circuit of the device is not disconnected or lowered, it is necessary to check the fuse for repair and replacement.
