ParasaswarCyliFor hydraulic cylinders in hydraulic elevators, it is not practical to change their effective working area A (equivalent to displacement) to adjust the speed. Generally the speed can only be adjusted by changing the flow rate. For variable displacement motors,ParasaswarHydraulic lifting platform, the pre installed equipment should be fixed speed regulation can change both the flow rate and the motor displacement.
After the pre installation is completed, and the positions of cables, and components such as the pre installed frame should be confirmed to be correct before reinforcement work can be carried out. Reinforcement requires welding or screws, and the hydraulic cargo elevator after reinforcement has robustness and safety.
Parasaswar.Below, we will analyze for everyone. According to the market survey and understanding conducted by the editor of hydraulic freight elevator manufacturers, many customers choose hydraulic elevators instead of elevators due to the following reasons: narrow transportation location, which cannot meet the requirements of elevators; Unable to excavate the elevator shaft at the working location; Elevators are expensive and difficult to meet their needs.
This paper briefly introduces some matters that should be paid attention to in the selection of oil tank for hydraulic elevators. The main functions of the hydraulic oil tank for elevators in the hydraulic systems of hydraulic machinery such as elevators and hydraulic elevators are oil storage, separation of air contained in oil and elimination of foam.
.The contact of the travel switch must be firmly opened and closed, and the contact crater should be polished in a timely manner.
After 5000 hours of elevator operation carry out medium maintenance on the mechanical and electrical systems.
Regularly check all wires and cables for damage. It is necessary to wrap and replace the damaged parts in a timely manner.
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.
What technical issues are required for the installation of hydraulic freight elevators? The installation of hydraulic freight elevators is actually quite complex. If you do not understand the equipment pictures designed by the elevator manufacturer and the detailed situation of the hydraulic freight elevator designed by the elevator manufacturer, installation errors may occur, leading to equipment failure of the freight elevator! When installing hydraulic freight elevators, it is necessary to accurately calculate the size of the pit. The guide rail hydraulic freight elevator is a freight elevator composed of chains, guide rail torque tubes, and other components, and wall mounted installation is chosen to enhance the stability of the freight elevator. Choosing the appropriate wall size also requires careful planning.
Motor not running: Check all components of the motor for damage and check if there are any problems with the circuit and wiring.
property right.When the hydraulic oil is insufficient, the hydraulic pump will experience suction, causing air to enter the hydraulic oil and producing high noise.
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,ParasaswarMobile hydraulic lifting platform, 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.
Set up warning lights around the guide rail type hydraulic cargo elevator equipment,ParasaswarHydraulic lifting table lifting, and the warning lights will light up to warn operators when loading and unloading materials. Idle personnel are prohibited from entering the operating range.
Reason: The lowering valve is not tightly closed. Cleaning method: Check if the lowering valve is powered on. If there is no power supply, clear the malfunction of the lowering valve itself or replace the lowering valve. It is necessary to keep the valve of the lowering valve clean and flexible.
Promotion.The contact of the travel switch must be firmly opened and closed, and the contact crater should be polished in a timely manner.
The hydraulic system of the fixed lifting platform of the hydraulic cargo elevator is equipped with anti fall and overload safety protection devices, and operation buttons can be set on each floor and the lifting platform workbench to achieve multi-point operation.
Therefore, in the hydraulic pipeline assembly line, it is necessary to avoid dead bends as much as possible and check the tightness of the sleeve in a timely manner.
Parasaswar.Emergency descent device: When a power driven chain elevator loses power, there should be a device to make the workbench emergency descend.
The manufacturer of the hydraulic cargo elevator tells you the reason and cleaning method: Reason: Overload cleaning method: Reduce the load to clean. Reason: The return valve is not closed. Cleaning method: Tighten the return valve to clean. Reason: The one-way valve of the manual pump is stuck and the return valve is malfunctioning. Cleaning method: Unscrew the bolt at the valve port of the oil pump, conduct maintenance, cleaning, and replace the cleaning hydraulic oil to clean.
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.
