Boiler Tube Repair - Learn some ways to restore Diesel engine high pressure pumps

Proper repair, calibration and Boiler Tube Repair (restoration of high-pressure diesel pumps) will help increase the life and performance of the pump. Let's learn about some common high pressure pump failures as well as how to restore them effectively.

Before Boiler Tube Repair, let's find out what a high pressure pump is?

To restore an effective high pressure boilers (Boiler Tube Repair), you need to learn some general information about this pump in advance. Diesel engine high pressure pump, also known as high pressure oil pump, is a device in the diesel engine fuel system that pumps fuel to high pressure through the high pressure oil pipe to the injector. fuel into the combustion chamber. The task of the high-pressure pump is to help the engine operate at maximum capacity but still save fuel and minimize emissions to the environment.

Classify some common failures and (Boiler Tube Repair) to restore high pressure pumps

In the process of using the high pressure pump (Boiler Tube Repair), some damage will inevitably occur, if detected in time, they will be effectively overcome without resorting to new replacement measures. The following is a solution to restore Diesel high pressure pumps when encountering some common failures.

Boiler Tube Repair - How to restore the high pressure pump when the cylinder and piston plunger is damaged

Damage to the cylinder and plunger piston will cause pump pressure and flow to drop, oil not getting to the injector, or a weak injector. There are many causes of this condition:

• The clearance between the cylinder and the plunger piston is worn out due to friction or using diesel oil that is dirty or mixed with water or has been used for a longer time.

• Piston is worn at the top edge and groove surface of the fuel supply area.

• Cylinders in the surface around the oil holes are worn because these areas are frequently exposed to the high-pressure fuel feed.

• Piston is bent and broken due to pressure, strong impact under high pressure, or it may be due to improper disassembly

The way to restore the high pressure pump (Boiler Tube Repair) in this case is to check for each cause and adjust accordingly.

Boiler Tube Repair - How to restore high pressure pump when damaged valve and high pressure outlet valve seat

Signs to identify this error are when the pressure of the high pressure fuel pump is reduced, the injector cannot inject fuel or the injection is weak, leading to a delay in the fuel injection time. When the engine power is reduced, the exhaust gas will have black smoke.

The cause of this phenomenon may be due to the long-term use of the valve seat and the high-pressure outlet valve base due to friction or dirty fuel. Or it may be due to a weak broken valve spring, worn out valve seat cushion. We can rely on these causes to have effective high-pressure pump recovery (Boiler Tube Repair) measures.

How to restore high pressure pump (Boiler Tube Repair) when pump damaged camshafts, hubs, bearings

We can recognize this situation when we feel the pressure of the pump decrease during operation or there is an unusual wooden sound when the pump is operating. The cause of this phenomenon may be because the pump camshaft is worn due to contact with the bearings, cam lugs, worn pins, broken due to pressure, and great friction after a period of use.

High pressure pumps or any other type of pump will not be able to discharge damage after a process of use. Knowing the cause will help you take measures to restore the pump (Boiler Tube Repair)

safely, less expensively and without having to buy a new pump to replace.
