For the mobile crushing station, its working process is closely related to the level of oil pressure, and too high or too low oil pressure will cause production failures and changes in output. So, what are the reasons for the low oil pressure of the mobile crushing station? This article will give you a detailed analysis:
Reason 1, insufficient oil, if the amount of oil in the mobile crushing station is insufficient, the amount of pump oil in the oil pump is reduced, resulting in a drop in oil pressure, which will aggravate the wear of the crankshaft and bearing, cylinder liner and piston;
The second reason is that the engine temperature is too high, which will not only cause the oil to become thinner, so that the oil pressure will drop, but also cause the aging and deterioration of the oil in the mobile crushing station;
Reason three, the oil pump stop or insufficient pump oil, the oil pump drive gear and drive shaft fixed pin break or mating key off, as well as the oil pump suction foreign matter and pump oil gear stuck, will cause the oil pump stop phenomenon, this time the oil pressure of the mobile crushing station will drop to 0, When the gap between the oil pump shaft and the bushing, the gap between the gear end face and the pump cover, the tooth side clearance or the radial clearance exceeds the allowable value due to wear, it will lead to the reduction of the pump oil and the decrease of oil pressure;

Reason four, after long-term use of the engine of the mobile crushing station, the coordination gap between the crankshaft and the connecting rod bearing will gradually increase, which is also one of the reasons for the drop in oil pressure;
Reason five, the oil filter is blocked, this time the oil filter base on the safety valve is opened, the oil is not filtered and directly into the main oil passage, if the opening pressure of the safety valve is adjusted too high, the oil filter is blocked, the safety valve can not be opened in time, so the oil pump pressure increases, the internal leakage increases, the oil supply in the main oil passage decreases, causing the oil pressure to drop;
Reason six, oil return valve damage or failure, generally speaking, in the use of mobile crushing station, if the oil return valve spring fatigue softening or improper adjustment, the valve seat and steel ball mating surface wear or by dirt stuck and closed loosely, the oil return amount will increase significantly, the oil pressure of the main oil passage will also decrease;
Reason seven, oil radiator or pipeline oil leakage, this phenomenon will also cause a drop in oil pressure, if the mobile crushing station in use, the pipeline is blocked by dirt, will also increase the resistance and reduce the flow of oil, oil pressure drop;
The oil pressure sensor of the mobile crushing station fails or the oil pipe is blocked, and the oil pressure gauge will show that the oil pressure drops;
For the mobile crushing station, if the oil is too dirty, too sticky, it is easy to block the oil tray, in the use of the station, when the engine is running at low speed, the oil pump is not large, the main oil channel can still establish a certain pressure, the oil pressure will be normal, but when the accelerator is running at high speed, The amount of oil absorption of the oil pump will be significantly reduced due to the excessive resistance of the suction cup, which will cause the display value of the oil pressure gauge to decline;

Reason 10, the oil grade is not correct or the quality is unqualified, different types of mobile crushing station need to use different oil in the production, if the oil grade of the equipment is not correct or the quality is unqualified, it will cause a decline in oil pressure and a decline in the working performance of the equipment;
11, the pressure regulator set pressure is low, this time the oil can not be effectively transmitted to the lubrication parts, resulting in mechanical failure, but if the oil pressure is too high, it will increase fuel consumption, increase the load to the oil pump and lubrication parts, damage the oil seal and cause oil leakage;
This paper mainly introduces the reasons for the low oil pressure of the mobile crushing station, the analysis of this problem is more detailed, mainly from 11 aspects, and a detailed introduction to these aspects, in the actual production, to avoid the wrong operation of these aspects, can effectively avoid the phenomenon of low oil pressure, and then ensure the smooth working process of the mobile crushing station.
