Hydraulic Elevator Oil Cooler

　　 When the hydraulic system of the hydraulic elevator is working, the oil plays a double function of lubricating and passing power. As the temperature rises, the oil's viscidity declines. If the oil film in the lubricating part has been destroyed, the leakage of oil increases, the sealing material ages in advance and the pressure of saturation oil steam rises. All of these affect directly the elevator precision, comfort, car loading and also the cooling effect of the oil-soaked electrical machine in the pump. If the elevator runs long time under high temperature, the oil will be oxidated, sedimentation will appear, and the movement of the pump and valve may be disturbed. When the oil temperature is over high, the hydraulic system may even go into the protection mode which will cause the accident of locking people in.

　　The hydraulic system works by vertical rise and fall. According to the law of conservation of energy, all the energy input into the system will go in to the system in the form of heat. If the natural cooling can not maintain the oil temperature in the permitted range, the oil cooler must be installed to take a obligatory cooling.

　　For the technical requirement of the hydraulic system, our factory takes the international-lead technology for heat exchanger, and developed the new generation -XFL series elevator condenser on the base of LK type oil cooler. It cools the air to keep the working oil at the set temperature and guarantees the hydraulic system work properly and continuously. The new style cooler has a much smaller size, and weight but higher Energy Efficiency Rate. The installation is very convenient with installation size, oil outlet, oil inlet match the oil container in other country .All the date of the cooler arrive at the level of similar foreign product.

(1)Air cooling; Stable and reliable effect;
(2)Working temperature can be freely set from 0℃ to 99.9℃;
(3)Show the oil temperature in the oil tank at any real time so that the changing of
        the oil temperature can be known directly;
(4)When the temperature arrives at the up limit, the cooler start to work when the
        oil temperature declines to the bottom limit, the air conditioner power off
        automatically.
＊We can add the oil filter according to the need of customers (precision is 10 micron),
   which can clean the pollutant automatically.
