In summer, the ambient temperature is high. If the oil is selected improperly, the oil pressure may be too low, and if it is severe, the engine may be damaged. Therefore, the vehicle must pay attention to the correct selection and use of lubricants.
The environment temperature is relatively high, and the engine is often in a high temperature state, which easily causes the lubricating oil to degenerate, the viscosity decreases, and the lubrication function is lost. Therefore, in the summer, special attention should be paid to the engine cooling system to ensure that it can work normally and avoid high temperature overheating of the engine.
The viscosity of lubricating oil changes with the increase of temperature, that is, the viscosity of the lubricating oil is reduced when it is heated, and it is easy to cause the lubricating oil to be consumed too quickly. Therefore, special attention should be paid to the inspection of the dipstick in summer, and if there is a defect, it must be added in time.
Heavy or relatively old cars can often use 50 or 20w/50 oil. Avoid excessively low oil viscosity caused by oil viscosity, causing unnecessary failure. Also pay attention to the engine water temperature and oil pressure at any time. If there is any abnormality, you should stop immediately to find out the reason. After troubleshooting, you can continue driving.
Slewing Controller is a kind of Tower Crane slewing control device, combined speed and voltage regulation and eddy current speed controling. The slewing control block control the speed of eddy current torque motor, to make the tower crane slewing mechanism start, working and stop smoothly. This kind of Slewing Controller is used to regulate and control the speed of three-phase torque motor of AC 50Hz, voltage 380V.
HRCV slewing controller is a hoisting slewing controller developed by our company according to service condition of customer.
The main technical feature as follows:
(1) This product combined the controller and thyristor module,the connection of the users is simple and easy.Prevent the damage of the controller and thyristor module caused by mis-wiring of the customer.
(2) Realize the best optimization of AC voltage control curve and DC voltage control curve.
(3) With the function of inching during operation, realize the accuracy.
(4) The electronic components adopt the imported industrial grade chip, on the control panel directly with power supply and direction indicator light.
(5) Adopt the coating treatment on the printed circuit board,enhance the dust prevention and anti-condensation capacity of the circuit board.
