Long term use Two construction pump Inevitably, wear and tear will result in lower efficiency. Therefore, after the lubricant is used for a period of time, two construction pumps must be replaced in time.
1, I know that lubricating oil, as the name suggests, is used for lubrication, but lubricating oil is also buffered except for lubrication.
When the pressure of engine cylinder rises sharply and suddenly increases the load of piston, piston pin, connecting rod and crankshaft bearing, lubricating oil can cushion the impact load.
This is a well-known main role. Lubricating oil forms oil film on the surface of friction between components, which reduces friction, wear and power consumption among components.
In the two construction, some parts of the pump will generate high-speed relative motion during operation, and the temperature will be higher if they are affected by friction and high temperature combustion. At this point, lubricating oil absorbs part of the heat when it flows through the surface of the component, and is distributed to the atmosphere through the oil dispersing oil heater and the oil pan, and the lubricating oil pumped by the vehicle acts. Cooling function to eliminate lubrication.
4, reduce noise.
The lubricant film between the working surfaces of the cement pump parts can reduce the impact noise between the metal parts, and the liquid lubricating oil has the ability of absorbing vibration.
In addition, what is the effect? Seal.
There is a gap between the cylinder wall of the engine and the piston, piston ring, piston ring and piston ring groove. The existence of these gaps tends to make the mixture in the combustion chamber enter the crankcase, which not only accelerates the degradation of lubricating oil. It can even reduce cylinder pressure and engine output. Lubricating oil can form oil film in the gap of each spare part to ensure the pressure of the cylinder, thereby playing a sealing role.
6, rust prevention and corrosion protection
The two time is that the pump lubricants are adhered to the surface of the parts to avoid direct contact between parts and water, air, gas and so on, and naturally prevent or mitigate the effects of corrosion and chemical corrosion.
