Kyle BridgeCanThere is air in front of the pilot valve of the elevator overflow valve noise overflow valve. The damping hole on the main valve core of the overflow valve is blocked by oil dirt, and the pilot valve and valve seat are matched without spring deformation or incorrect installation. The remote control port has excessive oil flow, low or high hydraulic oil viscosity, and resonance occurs with components in the circuit. Troubleshooting: Strengthen sealing, exhaust and clean the valve body several times, Make the damping hole unobstructed, repair or replace the spring, reduce the flow of the remote control port, replace the oil, and other components. The pressure setting of other components should not be similar to the pressure setting of the relief valve. 5. The noise of the elevator pipeline is usually caused by excessive dead bends or loose fixed sleeves in the hydraulic pipeline.
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.
Kyle Bridge.When working at heights, except for relevant personnel no one is allowed to walk or stay below the workplace. Fencing or other protective devices should be installed below the workplace to prevent falling objects from injuring people.
There are many reasons for unstable workbench descent, such as overload, unstable support, 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.
.When the hydraulic lifting platform is working, the load cannot exceed its rated load. When it is raised to a certain height, the larger the mass of the object, the greater the shaking
Hydraulic lifting table: the hydraulic lifting table is widely used in various industrial enterprises and production lines such as automobile, container, mold manufacturing, wood processing, chemical filling, etc., to meet the lifting needs of different operation heights, and can be equipped with various table forms (such as ball, roller, rotary table, steering, telescoping), and with various ways (separate, linkage, explosion-proof), it has stable and accurate lifting, frequent starting The characteristics of large load capacity effectively solve various lifting and lowering difficulties in industrial enterprises, making production operations smooth.
The contact of the travel switch must be firmly opened and closed, and the contact crater should be polished in a timely manner.
The electromagnetic coil of the electromagnetic directional valve is not firmly fixed, and frequent separation and suction can also produce high noise.
Hydraulic oil deteriorates or produces impurities. After long-term use of oil pressure, there may be impurities or deterioration in the oil. Sampling inspection should be carried out to see if there are solid particles, discoloration, and odor. If necessary, the oil should be changed. There may be blockage in the hydraulic pipeline of the hydraulic cargo elevator. The hydraulic pipeline is also a very important part, and it is necessary to check whether the hydraulic pipeline is smooth. Focus on checking whether each type of hydraulic valve includes one-way globe valve, electromagnetic directional valve,Kyle BridgeSmall hydraulic lifting and leveling, proportional control valve, overflow valve, etc. If there are problems, the hydraulic valve should be cleaned or replaced in a timely manner.
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, it is easy for hydraulic cargo elevator manufacturers to cause this problem.
When the hydraulic lifting platform is working, the load cannot exceed its rated load. When it is raised to a certain height, the larger the mass of the object, the greater the shaking
Surface paint quality: The paint should be smooth and flat, have good adhesion with metal, have uniform color, no bubbles, no cracks,Kyle BridgeHydraulic lifting platform supplier, and there should be no wrinkles, pits, paint leakage, and sagging.
The above are the working principles of three common elevators, and there are also some forms of elevators that are not common such as cylinder mounted elevators, curved arm elevators car mounted elevators, etc. Their common feature is the hydraulic principle for operation, which has been favored by many users.
new product.Remove the hydraulic oil tank filler cap, filter cover, inspection hole, 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.
Ensure a good power supply at the installation site, install a separate distribution box, and when using the distribution box, the electrical leakage switch must meet the requirements for construction elevators. If the installed construction elevator is variable frequency, the leakage switch should be compatible with the frequency converter when selecting it.
Surface paint quality: The paint should be smooth and flat, have good adhesion with metal, no bubbles, no cracks, and there should be no wrinkles, pits, paint leakage, and sagging.
Kyle Bridge.The smoothness of the gearbox, gearbox, external meshing gears, and hydraulic oil are all carried out according to the requirements in the smoothness table.

The remote control port has excessive oil flow, low or high hydraulic oil viscosity, and resonance occurs with components in the circuit. Troubleshooting: Strengthen sealing, repeatedly adjust the pressure, exhaust and clean the valve body several times, Make the damping hole unobstructed, repair or replace the spring reduce the flow of the remote control port, and other components. The pressure setting of other components should not be similar to the pressure setting of the relief valve. 5.
