Understanding the Oil Pump
Ah, the oil pump. The unsung hero of the injection molding machine. Without it, the world of plastic manufacturing would be in shambles. Well, maybe not shambles, but certainly not as smooth and efficient as it is today. So, let’s take a moment to appreciate this small yet mighty component of the machine.
Function of the oil pump:
The oil pump is responsible for, you guessed it, pumping oil. But it’s not just any oil; it’s the lifeblood of the machine. This oil ensures that all the moving parts are well-lubricated, preventing unnecessary friction and wear. Think of it as the machine’s personal massage therapist, keeping everything running smoothly. Without the oil pump doing its job, the injection molding machine could throw a hissy fit and malfunction, causing a whole lot of headaches for everyone involved.
Components of the oil pump:
Now, let’s dive into the juicy details of what makes up this vital component. The oil pump consists of various parts that work together harmoniously to keep the machine going strong. We have the pump body, the rotor, the crescent-shaped suction port, the discharge port, and of course, the gears. These gears do the heavy lifting, literally, as they rotate and create the necessary pressure to pump the oil throughout the machine. It’s like a well-choreographed dance, with each part playing its unique role to keep the show running smoothly. So, next time you see an injection molding machine in action, take a moment to appreciate the oil pump silently working its magic behind the scenes. Trust me, it’s a major player in the grand scheme of things. And remember, keep that oil pump well-maintained, and it will reward you with precise, efficient, and high-quality plastic products. Now, let’s move on to the not-so-fun part – the common causes of damage to the oil pump. Brace yourself, folks, this could get ugly.
Causes of Oil Pump Damage
The oil pump is the “heart” of the injection moulding machine’s hydraulic system. Therefore, at any time when the hydraulic system problems, we will often blame the problem on the oil pump. In fact, in terms of the cause of oil pump damage, because of the lack of oil pump itself caused by the phenomenon is rarely seen. More correctly, when the working condition of the pump deteriorates, it shows that in the hydraulic system, has hidden other problems of a symptom.
1. Air mixing
Air mixing, refers to a kind of bubble in the system of hydraulic oil in the spread of the phenomenon. When the oil system is compressed air bubbles facing the pump outlet pressure, this rupture effect will occur. This rupture effect will cause the pressure side plate inside the pump, wear-resistant side plate and other metal surfaces near the rupture point of the peeling phenomenon, and lead to extremely high temperatures in place.
Due to the air mixing phenomenon, the pump will produce a loud sound like thunder and lightning. The pitch of this noise increases as the pressure rises, and excessive air mixing can lead to emulsification of the hydraulic fluid (due to the large amount of water in the air). In addition, the compression of the air in the hydraulic fluid causes problems such as poor operation of the hydraulic components.
The possible ways of getting air into the pump:
1. Bad shaft seal.
2, the tank to the pump inlet part of the joint leakage.
3, the oil level is too low or return to the oil tank of the return pipe is installed on the oil surface, resulting in the oil tank of the hydraulic oil bubbles, not yet eliminated its bubbles when it is sucked back into the pump.
Is when the pressure is reduced to saturation vapour pressure below the presence of hydraulic fluid in the fluid occurs in a local cavitation phenomenon. To put it more simply, if the hydraulic oil is not completely filled with the space that should be occupied, i.e. there is a vacuum in the oil circuit, it will cause this cavitation phenomenon.
The noise caused by cavitation is similar to the noise caused by the air mixing phenomenon. The cavitation phenomenon is caused by the following factors:
1, pump and electric motor mismatch problem, resulting in pump speed is too high.
2, pump suction pipe too long, or for the suction port is limited.
3, the viscosity of the hydraulic oil is too high.
4, the tank on the discharge port is blocked.
5 Check the pump suction filter.
Any foreign matter in the circuit of a hydraulic system can adversely affect the efficiency of the hydraulic components and their circuits. Contamination can be solid, liquid or gaseous.
Most contaminants will cause frictional movement between the work piece and the tight clearance of the work piece, resulting in accelerated wear and cracking of the work piece.
Sources of contamination in the oil circuit can be broadly divided into
1. cast cylinder, oil block, oil tank interior, pipe joints, etc.
2. oil seal or O-ring embrittlement fracture.
3. Hydraulic oil deterioration at high temperature for a long time, resulting in oil contamination.
4. pump due to air mixing or cavitation caused by metal surface stripping material.
Because of more than the specified upper limit temperature, and cause fluid viscosity change a thermal phenomenon. Overheating will cause accelerated oxidation of the hydraulic fluid and make the hydraulic fluid viscosity deterioration, and cause a chain reaction, thus causing overheating of the real cause must be ruled out, so that the effective correction of this problem.
Causes of overheating:
1, overload operation, overpressure use.
2, caused by air mixing and cavitation phenomenon.
3, caused by oil contamination.
5. Excess pressure
Refers to the operating pressure is greater than the design pressure of the pump. Overpressure will make the pump internal workpiece suffered a great force and cause early damage to the internal workpiece.
Above is the impact of the injection moulding machine oil pump use of the reason analysis, in general, the oil pump by the external environmental factors have a greater impact, camel pack editorial reminder, in the use of must do a good job of maintenance and repair, in order to extend the use of the oil pump period.
