1. Pay attention to oil change
Summer falls, according to the lowest temperature in the field to select the fuel and smooth oil. such as the lowest temperature in-10 ℃ above, can be selected minus 10th diesel, lower than-10 ℃ should be selected higher marking diesel, prevent the formation of high temperature initiator of the poor oil, so that the machine can not start and operate normally. At the same time, the oil is also required for the equipment for summer special oil, to increase the start-up resistance to ensure smooth. Due to the low temperature in summer, the hydraulic oil viscosity increased, the hydraulic pump suction pressure increase, the formation of oil supply shortage, the impact of the performance of the operation of the correctness and sharpness of components, so also to choose the regular model of hydraulic cylinder oil.
2. Don't forget to preheat
For the initiator, when the start-up of high temperature due to the oil viscosity, will form a short smooth oil in the absence of the smooth point, not all over the various, when the initiator high-speed operation, light to form the crankshaft, camshaft and rocker shaft and other wear intensified, heavy will form a pull cylinder, burning tile and other major incidents. Therefore, the initiator to idle running a period of time after the start-up, after the water temperature to continue to add load. The same is true of the hydraulic system preheating. Through the low temperature, hydraulic oil viscosity, so that oil suction difficult, the lack of pump oil, the impact of performance components of the strength and sensitivity. If the load, because of the negative pressure is too large, can also make plunger pump copper hinge pull bad, forming a big incident. At the same time because of the hydraulic pressure is a smooth dependence of hydraulic oil, because of the lack of pump oil, smooth poor, will greatly affect the pump and motor life hydraulic cylinder. So start the initiator, should not add the load to the hydraulic cylinder parts operation several times, so that all the performance components of the move several, to ensure that all hydraulic components have hydraulic oil through, to prevent the control valve attack card lag formation of the construction work of concrete thermal physical parameters measuring instrument.
3. Add Antifreeze
The temperature landing, equipment oil cylinders, hydraulic pipe joints, such as sealing parts will be cracked compressed formation of leakage, the transmission of connectors, bolts will also be affected by high temperature formation strength, stiffness landing, such as the initiator side of water seal cover plate leakage, drive shaft screw loose, pin cohesion and so on. Therefore, to strengthen the review, timely invention of the problem, the small hidden dangers to remove, to prevent the cause of large failures. At the same time to enhance the task of the remaining, high temperature of smooth fat activity poor, butter more timely to compensate. About water-cooled initiators, should be in time to change the antifreeze, to prevent frost cracking organism, cooler incident attack. Every day before and after work will be rigorous review to prevent the attack of man-made incidents, to ensure the normal operation of equipment, to ensure the normal summer construction.
