the oil temperature protection device sends a signal to suspend the use of the elevator. The elevator can only be started when the oil temperature dropsLv Liang

Electric elevators used in various places.Tank oil temperature protection: When the oil temperature in the tank exceeds the standard setting value,The downward movement of the hydraulic cylinder (i.e. heavy object lowering). 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 passes through the balance valve, hydraulic control one-way valve, energy-saving valve, and explosion-proof electric valveThe bearing capacity of the ground under the concrete foundation plate should be greater than .Mpa.Uiju,The hydraulic oil forms a certain pressure by the vane pump, and enters the lower end of the hydraulic cylinder through an oil filter, throttle valve, hydraulic control one-way valve, and balance valve, causing the hydraulic cylinder to move upwards and lift heavy objects. The return oil at the upper end of the hydraulic cylinder returns to the oil tank through the explosion-proof electromagnetic directional valve, and its rated pressure overflow valve is adjusted. The pressure gauge observes the reading value on the pressure gauge. The downward movement of the hydraulic cylinder (i.e. lowering of heavy objects).Principle of electric elevator rotary valve: When the electric elevator rises the rotary valve will automatically open. To close the plug valve, it is necessary to first turn the handle to turn the plug to a degree position until it is closed, and then turn the transmission handwheel to lower the plug and achieve sealing.Tank oil temperature protection: When the oil temperature in the tank exceeds the standard setting value, the oil temperature protection device sends a signal to suspend the use of the elevator. The elevator can only be started when the oil temperature drops

The angle between the wall bracket and the horizontal plane should comply with the requirements of the user manual.Do not move after lifting, and do not lift until the four legs are firmly supported.The end height of the guide rail frame above the high attachment point should comply with the provisions of the user manual.Online consultation,Setting requirements: The anti loosening and anti loosening parts between the connecting parts should comply with the provisions of the user manual and should not be replaced by other objects. For connecting bolts with pre tightening requirements, a torque wrench or special tool should be used to accurately tighten the bolts to the specified torque value according to the specified tightening sequence. When installing standard section connecting bolts, it is advisable to place the screw at the bottom and the nut at the top.Before operating the construction electric elevator, routine inspections should be carried out according to regulations and inspection records should be filled out.When the distance between the outer edge of the construction electric elevator and the edge line of the external overhead power line cannot meet the requirements in the table above, effective protective measures should be taken.

Buffer. In order to increase the energy for the car to hit the top or sink to the bottom. Remove rubber or sponge from the buffer and cabin to increase their impact energy; Rope groove slipping and other accidents caused the car to suddenly fall, resulting in a safety clamp. To prevent breakage of the lifting wire rope. A safety clamp that can simultaneously cut off the power supply and stop the car from falling should be removed from the car. A car without safety tongs is not allowed to ride or carry people. If it is a simple electric elevator, there should be a safety device (such as a safety stop pin) to prevent people from suddenly falling when loading and unloading goods in the car; Electric elevators with three or more floors (including three floors) for passengers or passengers.Quality assurance,The bearing capacity of the ground under the concrete foundation plate should be greater than .Mpa.Safety devices: Electric elevators for construction should be equipped with overload detection devices. When the load inside the cage exceeds % of the rated load capacity, the overload detection device will give a warning signal inside the cage,Once again, weekly inspections should be conducted to check whether the connecting screws at various parts of the lifting platform are tightened,Lv LiangHartwan, whether the sealing rings are damaged or ineffective, scissors and whether the oil cylinder is leaking. It is necessary to clean the lifting frame,Lv LiangBecks, wiring,Lv LiangHam,Operating cost advantage and low failure rate: Due to the use of advanced hydraulic systems and good methods, the operating failure rate can be reduced to a low level.Setting requirements: The layout and installation of all cables and wiring of electric elevators should be able to prevent mechanical damage.To meet the needs of choreographers and choreographers in different plays, different heights of the lifting platform can be used to change the shape of the stage according to the requirements of the choreographers and choreographers, in order to adapt to the requirements of the plot for the scenery or venue, and save manpower and material resources for setting up. By using the tilting device of the lifting platform to form a tilted platform, a better highlighting effect can be achieved in various performances. According to the needs of the plot, special atmosphere and effects can be created. Even simple stage machinery often participates in performance activities, creating unexpected atmosphere and effects according to the needs of the plot. For example, using the low-speed descent of the lifting platform to represent a sunken ship in the sea, using the valves on the lifting platform and the sudden disappearance and appearance of actors on the lifting platform.
