The Diesel Engine Water Pump's Structure and Operation

Image
  The Structure and Operation of a Diesel Engine Water Pump are as follows: The water pump impeller is inserted in the volute after the casing is formed into a volute shape. Four stud bolts link the water pump bearing seat to the water pump housing, and a pad in the middle prevents water leakage. Two rolling bearings support the water pump shaft on the water pump body, the front end of which is pressed and riveted to the water pump impeller, and the rear end of which is attached to the pulley via the semicircular key on the conical surface. On the water pump bearing seat, there is a screw-cap oil cup; fill it with calcium-based lubricating grease and twist the cup cover frequently to allow the lubricating oil to enter the bearing and lubricate the rolling bearing. When the water seal component rotates, the water seal four-corner plate made of wear-resistant material rubs against the central circular seat surface of the bearing seat to seal, preventing the cooling water from flowing out

Is Buying the OEM Engine Overhaul Rebuild Kit Necessary?

Image
 If you're familiar with Landtopmall, you should be aware that we sell aftermarket diesel engine parts. But do you understand the distinction between aftermarket and OEM parts? Maybe you do, but we get a lot of calls, so no. Genuine aftermarket parts are those that are not manufactured by the engine manufacturer. OEM stands for Original Engine Manufacturer, and it refers to the firm that created and/or sold the original engines. In the large diesel market, for example, Caterpillar and Cummins are the two leading OEMs. When an engine needs to be serviced, the usual assumption is that only the OEM can provide the correct or high-quality parts. Aftermarket parts have a negative reputation for being ragged, not durable, or installed incorrectly. But, what is the reality? True, OEM accessories are the best option, but are they the only ones? OEM Engine Rebuild Kits The Benefits of Purchasing an OEM Rebuild Kit The benefit of purchasing an OEM rebuild kit is that you'll get high-qual

The Common Damage of Diesel Engine Crankshaft and its Inspection and Repair

Image
 The crankshaft's job is to work with the connecting rod to convert the piston's gas pressure into torque and send it to the driven working machine. The crankshaft is subjected to the action of gas pressure as well as the inertial force and moment generated by reciprocating and rotating motion during engine operation. The crankshaft generates complex alternate stresses such as bending, torsion, shearing, tension, and compression as a result of these cyclically changing loads. Bending, twisting, and breaking the crankshaft are common difficulties. The crankshaft journal rotates at a fast relative speed due to high gas pressure and inertial force, making liquid lubrication impossible during alternate working circumstances. As a result, journal wear is unavoidable. The failure of the crankshaft installation to satisfy the standard criteria, inappropriate selection of bearing bushes, and improper use and maintenance will all exacerbate the crankshaft damage during use and maintenan

Why does the Water Tank of a Diesel Engine "Boil"?

Image
 Water and bubbles are streaming out of the diesel engine's water tank coolant filling port, resembling boiling water in a pot. The high temperature of diesel automobiles without a cooling system could be attributed to the radiator's inadequate heat dissipation. The heat dissipation area of the radiator and the windward region of the radiator will be reduced as debris adheres to the radiator's surface, lowering the radiator's heat dissipation capacity. If it is reduced, the temperature of the diesel engine will rise. Cleaning can be done at a 4s shop or a repair shop. It's also conceivable that the thermostat isn't working properly. The thermostat is a device that regulates the coolant flow path. The big and small circulation of the engine will be damaged if it becomes stuck or fails, and the heat of the diesel engine will not be adequately dissipated. The following is to share the failure reasons and processing experience of diesel engine boiling for reference:

Why does the Engine Need Forced Crankshaft Ventilation?

Image
 One of the most important systems on a typical internal combustion engine is the forced crankshaft ventilation system, generally known as the PCV system. The high-pressure combustible mixture and the burned gas in the combustion chamber will more or less enter the crankshaft through the gap between the piston ring and the cylinder when the engine is running because the piston ring is not entirely sealed. blow-by effect unburned fuel gas, water vapor, and exhaust gas are the main components of blow-by gas. If the gas builds up too much over time, it will cause several failures. LandTopMall are professional engine part suppliers , we have many years of experience so we are also able to provide you with better service. First, the oil is diluted, which decreases its performance and speeds up its oxidation and degradation. Second, water vapor from the blow-by gas component condenses in the oil, creating sludge and clogging the oil circuit. Third, the acid gas in the blow-by gas will combin

What is the Function of a Connecting Rod?

Image
 A connecting rod is a component that connects the crankshaft to the pistons in a reciprocating engine. The connecting rod and crankpin turn the piston's reciprocating action into the crankshaft's rotational motion. The connecting rod's primary role is to convey the piston's tension and compression forces. In EC and IC engines, connecting rods are most typically employed. Forged steel is used for the connecting rods. There's an I-beam part in that one. Connecting rods are also made of aluminum alloys. The connecting rods are positioned in particularly equal weight groupings to keep the engine balanced. When the engine pistons and connecting rods are lightweight, the engine will be able to provide higher output while experiencing less vibration. The engine requires a light, stiff, and durable connecting rod to transmit thrust from the piston to the crankpin. Power is transferred from the piston to the crankshaft via the connecting rod. It's necessary to have mech

Why did the Connecting Rod Break?

Image
  Burning of Connecting Rod Bearing The following factors contribute to connecting rod bearing bush burning: high oil temperature (above water temperature), low oil pressure, harsh driving, power loss, black smoke, or even flameout; However, there is an unusual noise, and there is metal dust in the oil pan. Reason: due to a lack of oil, an oil film cannot develop between the journal and the bearing bush, resulting in semi-dry or dry friction. As a result, the temperature rises significantly, leading the bearing bush alloy to melt and bite each other. Low oil volume, blocked oil passages or filters, and low oil pressure; bearing clearance is too small or too large; oil quality does not meet the requirements, such as oil that is too thin, low viscosity, or oil that contains impurities; the engine has been overloaded for a long time, the speed is low, the bearing bush pressure is increased, the oil supply is reduced, the journal and bearing bush are not uniformly worn, the axial wear is u
