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, so that the descent speed does not change due to heavy objects. The throttle valve regulates the flow rate and the ascending and descending speed. To ensure safe and reliable braking and prevent accidents, 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.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.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,Swarth20 meter hydraulic lift, which cause electric motors to sweep and produce noise; The cooling fan of the electric motor is damaged or not firmly fixed, resulting in high noise; The electric motor is not firmly fixed and can also cause vibration producing high noise.Excellent quality,The elevator itself has a simple structure and is easy to maintain, which has been favored by a large number of enterprises and individual customers. Hydraulic elevator is a multifunctional heavy loading and unloading mechanical equipment. The lifting system of hydraulic elevators is driven by hydraulic pressure, also known as hydraulic powered elevators.Optional configuration of fixed lifting platform: The fixed lifting platform can be equipped with auxiliary devices according to usage requirements, and can be combined in any combination, such as the safety protection device of the fixed lifting platform; Electrical methods; Form of work platform; Power form, etc. The correct selection of various configurations maximizes the functionality of the lifting platform and achieves effective use.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.
If the circuit of the device is not disconnected or lowered, it is necessary to check the fuse for repair and replacement.Latest quotation, draw on the guide rail lifting platform, prohibit any idle personnel from entering the work area, ensure that the work area is free of clothing, and maintain a clean and tidy workplace.Low power consumption: Hydraulic elevators are driven by the pressure generated by their own weight, greatly saving energy. Long term improvement of various brand products such as elevator manufacturers, with complete designated products and quality assuranceThe smoothness of the gearbox, gearbox external meshing gears, and hydraulic oil are all carried out according to the requirements in the smoothness table.Swarth,After hours of elevator operation, carry out medium maintenance on the mechanical and electrical systems.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 %.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.
The quality is very good, really good, SwarthHydraulic lifting platform frame the same as the picture, the packaging and quality are also very good,
