BeijingHydraulThe development of elevators is at its peak as many manufacturers have chosen more multi-story buildings to fully utilize the site, so they also need a device to facilitate the improvement of goods.
The contact of the travel switch must be firmly opened and closed, and the contact crater should be polished in a timely manner.
Beijing.Today, we will share with you why hydraulic cargo elevators are ideal equipment for transporting goods?
Reason: The lowering valve is not tightly closed. Cleaning method: Check if the lowering valve is powered on. If there is no power supply,BeijingHydraulic aluminum alloy lifting platform, 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.
.Do not use hydraulic lifting equipment with malfunctioning issues. The problem should be resolved before carrying cargo.
Hydraulic elevator manufacturers remind us that the basic principle of the hydraulic elevator speed control circuit is that the system often needs to adjust the movement speed of the hydraulic cylinder and hydraulic motor to adapt to the working cycle needs of the main machine. The speed of hydraulic cylinders and hydraulic motors depends on the displacement and input flow rate. It can be seen that changing the flow rate or displacement can affect the speed of the cylinder and motor.
What are the methods for reducing shaking on lifting platforms? Reducing the shaking of the lifting platform can reduce the psychological obstacles of the operators, ensure the smooth progress of the operation, and also greatly help improve safety. Warm reminder: safety, do not operate blindly. Lifts are widely used in many places, and their working principles vary. Today, we will analyze the working principles of elevators. The types of elevators are generally divided into the following: fixed elevators, This type of elevator uses hydraulic oil cylinders and pump stations to transmit power, in the form of a scissor fork type. According to customer requirements, the length of the support rod for the scissor fork, the number of layers, the angle of the angle axis, and the expansion and contraction of the oil cylinder complete the lifting operation. Its advantages are large load-bearing capacity, and high safety.
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.
Carefully prepare a special construction plan for installation and construction, and provide safety technical disclosure to installation personnel.
Remember not to overload, overload is the root cause of many faults.
Inspection requirements.Regularly check all wires and cables for damage. It is necessary to wrap and replace the damaged parts in a timely manner.
Road noise can also occur if tires are crushed against objects that are prone to noise. The shaking amplitude of the scissor type lifting platform is proportional to its lifting height. The higher the height, the greater the shaking. When using it at a working height of 10 meters, if possible, please use safety protection measures
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.
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 new seal is too tight, 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, 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, open the tank cap.
One of the executing components of the hydraulic cargo elevator system is the hydraulic cylinder. The hydraulic cylinder is responsible for linear lifting or retraction. Its characteristics are light weight, high power, simple structure, convenient maintenance, low motion inertia, frequent commutation,Beijing10 meter hydraulic lifting platform, and convenient remote control. Hydraulic cylinders are widely used in various single acting hydraulic cylinders as an example to analyze the conversion of hydraulic energy into mechanical energy for linear motion.
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.
Beijing.Therefore, the wholesale manufacturers of hydraulic elevators remind that there are three main ways to adjust the speed control circuit: throttling speed control circuit: quantitative pump oil supply, 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.
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, heat dissipation, separation of air contained in oil and elimination of foam.
Load bearing capacity: The lifting platform is placed on a horizontal support surface, and the workbench is evenly loaded to 125% of the maximum load capacity. After lifting 100 times, each load-bearing component must not have deformation or cracks.
