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, producing high noise.
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,GleevecFixed electric hydraulic lifting platform, 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.
Gleevec.Hydraulic elevators have two working periods and two end dwell times within a working cycle. Working hours refer to the period of lifting and falling objects. The suspension period refers to the period during which the machine temporarily stops working at the required height of rest. Therefore, each working period is divided into three different stages: starting, constant speed lifting, and braking.
Next, the hydraulic cargo elevator manufacturer will explain the maintenance of the mechanical equipment of the elevator: the brakes of each organization should be frequently checked and adjusted to ensure the clearance between the brake pads and wheels is sensitive and reliable. On the surface, there should be no dirt present. If there is dirt, it is necessary to wash it off with gasoline or thinner.
.Protective device: In case of power or oil circuit failure, there should be a safety rope to prevent the workbench from falling out of control. (Allow controlled descent)
Voltage too low: Measure the starter voltage, with an allowable fluctuation range of± 10%.
Lines of various safety equipment
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, the new seal is too tight,GleevecHydraulic lifting platform, 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, it can reduce vibration and noise, and the pipelines should avoid dead bends as much as possible.
In on-site hydraulic elevators, it is difficult to detect the rising position, impact noise,GleevecHydraulic lifting table small, and oil film leakage of hydraulic cylinders. Field observations have shown that the excessive lifting speed of the hydraulic cylinder has led to an increase in failure rate, seriously affecting production efficiency. The unstable hydraulic lifting requires an analysis of the hydraulic oil flow rate. Hydraulic pressing oil has poor quality and contains a large amount of impurities, which can also prevent slow and unstable lifting. In addition, there are other reasons: lifting the composition of the hydraulic ring. Oil pump, safety valve, directional valve, directional valve, one-way throttle valve (without throttling), and lifting cylinder.
The installation personnel should have the qualification for installing hydraulic cargo elevators, carefully implement the special construction plan for installation and construction, and provide safety technical disclosure to the installation personnel for technical design.
Sincere service.The 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.
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, stable lifting, and high safety.
After 5000 hours of elevator operation, carry out medium maintenance on the mechanical and electrical systems.
To consider its capacity generally mobile equipment takes 2-3 times the high flow rate of pump Z, and fixed equipment takes 3-4 times.
market price.The contact of the travel switch must be firmly opened and closed, and the contact crater should be polished in a timely manner.
Cleaning and maintenance: When there is oil in the oil tank or when oil is refilled, it is necessary to ensure the cleanliness of the filter tank cover. Clean the oil and funnel or container before use. Never bring dirty things into the system, only clean oil.
I believe many people want to know about the maintenance issues of guide rail hydraulic lifting platforms, as it is related to their service life. During use, frequently check the connection of each part. If loose, tighten it. When the body is under pressure, the tightness of the connecting bolts of the body should be checked (the pressure state that can be used). All connecting shafts should have split pins and hydraulic cargo elevators should be fully opened.
Gleevec.Check valve leakage: If the natural wear of the check valve exceeds the specified value after long-term use it will cause leakage. Disassemble and clean the check valve, 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 and replace it if necessary.
Therefore, 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.
The contact of the travel switch must be firmly opened and closed, and the contact crater should be polished in a timely manner.
