Detailed product information

Constructive forms: there are mainly two types: gear and rotary. The type of gear gear is divided into type with internal hook and type with external hook, and the type of rotor usually has the internal and external structure of the rotor engagement.

Principle of work: if you take a gear type as an example, then when operating the engine, the sliding gear on the distribution shaft drives the gear of the oil pump transmission, forcing the active gear to rotate, forcing the driven gear to rotate in the opposite direction and sending oil from the oil intake between the gap between the gap between the gap. teeth and wall wall into the chamber oil release. The oil absorption chamber forms a low -pressure oil tray and continuously rotates to ensure oil supply.

Characteristics of the material: the pump body is usually made of high -strength cast iron or aluminum alloy, which has good wear resistance and heat transfer. Gear or rotors are made of high -quality alloy steel and treated with hardening and grinding. They have high hardness and good strength and can withstand wear at high oil pressure and high speed. The seals are made of oil -resistant rubber or fluorine and other materials that provide good tightness and prevent oil leakage.

Parameters of performance: various models of oil pumps of Shanghai Diesel engines have different flow and pressure speeds. For example, some common models of oil pumps may have a flow rate of 50-100 liters per minute and a pressure of 2-4 bar at a engine speed of 1500-3000 rpm to meet the needs of the engine in lubrication in various working conditions.

Stages of installation

Preparation before installation: Prepare the necessary tools, such as wrenches, screwdrivers, etc. Clean the outer surface of the engine and the location of the oil pump from dust, oil and pollution. Check the appearance of a new oil pump for damage or deformation, check the completeness of all parts and make sure that the model corresponds to the engine.

Disassemble the related details: Drain the engine oil and remove the engine oil tray. If pipes, wires or other components are connected to the oil pump, first remove them and place them for the correct installation in the future.

Install the oil pump: looking through the mounting hole of the oil pump, turn the flywheel to move the cam back, find the gearbox fork and adjust the throttle so that the fork is in the center of the hole. Install the oil pump into the middle position, then carefully install the oil pump on the inner shaft of the crankshaft, combining the mounting holes and installation pin to make sure that the installation is correct. Tighten the installation screws evenly, but do not pull.

Connect pipes and components: correctly connect oil pipes, wires and other components connected to the oil pump, in accordance with the marking and make sure that the connection is reliable and does not allow the risk of weakening or leakage.

Checking and adjusting: After installation, check whether the oil pump is reliably installed and whether the gearbox is correctly touched on the rail. Turn the crankshaft to check the smoothness of the oil pump and the absence of seizure or abnormal resistance.

Add motor oil: add the required amount of engine oil, which corresponds to the specifications through the oil -polling hole. Before starting the engine, the oil level should be within the normal range of the probe scale.

Launch and check: Launch the engine, check whether the oil pressure indicator goes out, and check if the oil pressure is within the normal range. Listen to the sound of a working engine to make sure that the oil pump is working normally, without unusual noise or vibration.

Common errors

The oil pressure is too low: the wear of the internal parts of the oil pump, for example, the wear of the gears or rotors, leads to an increase in the clearance, which leads to an increase in oil leakage and a decrease in pressure. The oil filter is clogged, which increases the resistance of the oil flow and makes it impossible to create normal pressure with an oil pump. If the oil pump pressure restriction valve is faulty, the force of the pressure valve sprout is not enough or the valve core jammed, the oil pressure will be dropped prematurely, which will lead to low oil pressure.

The oil pump does not rotate: the drive gear or the oil pump chain is damaged, for example, the teeth of the gear or chain are broken, due to which the oil pump cannot receive power. Engine failure. For electric oil pumps, a short circuit may take place, a circuit break or the engine control circuit in the engine winding, which leads to the engine failure.

Oil pump leak: the laying of the pump body is aging and damaged, losing its sealing properties, which leads to a leakage of oil through the joint surface between the pump body and the engine cylinders block. Weakened oil pipeline joints or broken oil pipelines can cause oil leakage from the connection. If the seal of the oil pump shaft is damaged, the oil will flow along the pump shaft.

Unusual noise: extraneous objects such as metal garbage, sand, etc., which causes an abnormal noise when working gears or rotors, fall into the oil pump. The oil pump is installed unreliable, which leads to vibration and noise when operating the engine.

If the common malfunctions of the Shanghai Diesel engine oil pump occur, the following malfunctions eliminate the following methods:

Oil pressure is too low

Check the wear of the internal parts of the oil pump: if you suspect that an increase in the clearance is caused by wear of gears or rotors, disassemble the oil pump and using instruments such as a caliper, measure the size of gears or rotors, as well as a gap between them. If the wear is significant, you should replace worn parts or the entire oil pump node.

Check the oil filter: if the filter is clogged, replace it in a timely manner. When replacing, make sure that the filter model corresponds to the engine, and install it in accordance with the correct installation method.

Check the pressure limit valve: disassemble the pressure limit valve and check if the spring force is normal. It can be compared with a new spring valve. If the force of the spring is insufficient, a new spring should be replaced. At the same time, check if the valve core is stuck. If it is stuck, clean the valve core and the valve saddle with a detergent, and then apply the corresponding amount of lubricating oil so that the valve core can move freely.

The oil pump does not rotate

Check the drive gear or chain: for gear oil pumps, check if there are broken teeth or severe wear on the drive gear. If any problems are detected, damaged gears should be replaced. On oil pumps with a chain drive, check the chain for ruptures, sags or wear. If problems arise with the chain, it should be replaced in a timely manner and adjust the tension of the chain.

Check the engine of the electric oil pump: Using the multimeter, measure the engine resistance to determine whether the winding is closed or whether it is short circuit. If the resistance value is abnormal, this means that the engine winding is faulty and the engine must be replaced. At the same time, check the engine control circuit for any problems, such as blocked fuses, faulty relay, weakened linear compounds, etc. Repair or replace the damaged components of the circuit to ensure the normal operation of the engine.

Leakage of the oil pump

Check the gasket of the pump housing: if at the junction of the pump housing and the engine cylinders the oil leak is detected, the oil pump should be disassembled to check the gasket for aging or damage. If problems arise with the laying, replace it with a new one, and during the installation, make sure that the gasket is installed correctly, and the sealing surface is clean and does not have contaminants.

Check the compounds of the oil tubes and oil tubes: check if the compounds of the oil tubes are weakened. If so, tighten them with a wrench. Check if there are cracks or wear on an oil tube. If so, replace it with a new one. When replacing the oil pipe, choose an oil pipe of the right diameter and material, as well as ensure the reliability of the connection.

Check the seal of the oil pump shaft: if the oil flows along the pump shaft, disassemble the oil pump and check if the shaft seal is damaged. If the shaft seal is damaged, replace it with new ones. When installing the shaft seal, pay attention to the direction and installation method to guarantee that the shaft seal is installed in place and is well sealed.

Abnormal noise

Check if there are foreign objects inside the oil pump: disassemble the oil pump and check if there are foreign objects inside, such as metal trash, sand, etc. If outsiders are detected, the inside of the oil pump should be thoroughly cleaned and the details related to it should be checked for damage. In case of damage, it should be replaced in a timely manner.

Check the installation of the oil pump: check if the oil pump fasteners are weakened. If they are weakened, tighten them in accordance with the indicated puffing moment. Check the reliability of the oil pump with the engine and the absence of vibration transmission. If the installation is unreliable, reinstall the oil pump and make sure that it is installed in the correct position and securely fixed.
