During operation, the high-temperature oil in the hydraulic system of the on-board crane flows through the hydraulic oil cooling device, and the heat is efficiently heated in the heat exchanger and the forced cold air. In exchange, the temperature of the hydraulic oil is lowered to the working temperature to ensure that the main engine can continue to work normally and the on-board crane work can be performed smoothly. Assume that your lorry crane is operating slowly after working for a period of time. Lifting ability can be reduced. The hoisting will initially present a slippery hook. The hydraulic oil heating gripper will indicate that the hydraulic radiator of your lorry is in doubt. Assuming that it is not replaced in time will not only constitute continuous leakage of hydraulic oil, but also will reduce the service life of hydraulic components and will greatly increase engine fuel consumption. Then, what should we pay attention to when replacing the hydraulic radiator with the vehicle? The time required for the installation of a hydraulic radiator onboard the vehicle satisfies the following requirements: 1, radiator device good ventilation 2. The cooling fan should be separated from the device wall by more than 30 cm. 3, the pipe diameter is necessary to cooperate with the radiator tooth mouth can not be reduced 4. Use direct heads as much as possible to reduce oil return resistance 5, as much as possible to reduce the device pipe bending times The description of the high temperature of the hydraulic system in the truck crane (with truck crane truck) 1, the mechanical attack thermal deformation, hydraulic components in the coefficient of thermal expansion is not the same as the moving parts of the smaller space and stuck, resulting in failure of the action, affecting the hydraulic system's transmission accuracy, resulting in deterioration of the quality of the parts. 2. The air pressure of the oil is reduced, dissolved air in the oil escapes, and cavitation occurs, resulting in a decrease in the working function of the hydraulic system. 3. Reduce the viscosity of the oil and increase the leakage. The volumetric power of the pump and the power of all systems will be significantly reduced. As the viscosity of the oil is reduced, the oil film of the moving parts such as the slide valve is thinned and cut, and the frictional resistance increases, resulting in increased wear. 4. Accelerate the oxidative change of the oil and separate the asphalt material to reduce the service life of the hydraulic oil. Disengagement blocks the orifices of the damping and the slit-type valve ports, resulting in the pressure valve being stuck and unable to move, the metal lines extending and bending, or even breaking. 5. Deformation of rubber seals, accelerated aging failure, reduced sealing function and service life, constitute a leak. [Company]: Cheng Li Special Purpose Vehicle Co., Ltd.

Melamine Powder is an organic compound with the formula C3H6N6 as Rubber And Plastic. This white solid is a trimer of cyanamide, with a 1,3,5-triazine skeleton. Melamine Glazing Powder like cyanamide, it contains 67% nitrogen by mass, and its derivatives have fire retardant properties due to its release of nitrogen gas when burned or charred. Melamine Resin Powder can be combined with formaldehyde and other agents to produce melamine resins. Such resins are characteristically durable thermosetting plastic used in high pressure decorative laminates such as Formica, melamine dinnerware, laminate flooring, and dry erase boards. Melamine foam is used as insulation, soundproofing material and in polymeric cleaning products, such as Magic Eraser.
Melamine Moulding Powder is sometimes illegally added to Ethylene-Vinyl Acetate food products in order to increase the apparent protein content.Ingestion of melamine may lead to reproductive damage, Pvc Resin or bladder or kidney stones, and bladder cancer. It is also an irritant when inhaled or in contact with the skin or eyes.
