A diesel engine that completes a working cycle through two strokes of the piston is called a two-stroke diesel engine. The oil engine completes a working cycle and the crankshaft makes only one revolution. Compared with a four-stroke diesel engine, it has improved working power. In terms of specific structure and working principle There are also big differences.The basic structure of a two-stroke diesel engine is the same as that of a four-stroke diesel engine. The main difference lies in the valve train. Two-stroke diesel engines do not have an intake valve, and some do not even have an exhaust valve. Instead, a scavenging port and an exhaust port are provided in the lower part of the cylinder; or a scavenging port and exhaust valve mechanism are provided. A scavenging pump driven by a moving part and a scavenging tank for storing compressed air are specially set up, and the gas distribution is completed by the cooperation of the piston and the air port, thereby simplifying the structure of the diesel engine. The figure shows the working principle of a two-stroke diesel engine. The scavenging pump is attached to one side of the diesel engine, and its rotor is driven by the diesel engine. Air is sucked in from the pump, compressed and discharged, stored in a scavenging tank with a larger volume, and maintained a certain pressure in it.The fuel valve test device is an indispensable tool for testing the fuel valve of a diesel engine. Various fuel valve test devices can be selected according to different diesel engine models. DetailIntroduction to marine pumps
Introduction to marine pumpsMarine pumps refer to various pumps for ships that meet the requirements of ship regulations and ship technical conditions. They are often used to transport various liquids such as sea water, fresh water, sewage, lubricating oil and fuel oil on ships.Marine pumps are widely used in modern ships. Generally speaking, a diesel-powered cargo ship requires 36-50 pumps of various types, which account for 20%-30% of the total marine machinery and equipment.1.Marine pumps are widely used in modern ships. According to their different uses, they can be divided into2.General purpose pumps for ships. There are bilge water pumps, ballast water pumps, fire pumps, daily fresh water pumps, daily sea water pumps, hot water circulating pumps; and general pumps that double as ballast, fire fighting, and bilge water pumps.3.Pumps for marine power plants. There are fuel pumps, lubricating oil pumps, sea water pumps, fresh water pumps, hydraulic pumps for steering gears or other deck machinery, feed water pumps for boiler installations, cooling water pumps for refrigeration installations, sea water pumps and condensate pumps for sea water desalination installations.4.Special pumps for special ships. Certain special purpose ships are also equipped with special pumps for their special operational requirements, such as cargo oil pumps for oil tankers, mud pumps for dredgers, salvage pumps on salvage ships, water jet propulsion pumps on water jet propulsion ships, Fishing pumps on non-net fishing boats, etc.5.Pneumatic high-pressure pumps and manual hydraulic pumps belong to the supporting hydraulic pumps for hydraulic tools of diesel engines.

Maintenance of separate hydraulic jack1. The hydraulic oil should be replaced regularly during the use of the hydraulic jack to ensure the cleanliness of the oil and prolong its service life.2. Each time the jack is used, a full-stroke telescopic test run is required for 5 strokes and then run with load. Why do you do this? This can exhaust the air in the cylinder, preheat the cylinder and piston, and effectively avoid the presence of air or water in the system.3. Control the system temperature. Excessive oil temperature will reduce the service life of the seal and may indeed cause the hydraulic jack oil seal to leak. Long-term high oil temperature will cause the seal to permanently deform or even fail completely.4. Protect the outer surface of the piston rod to prevent bumps and scratches from damaging the seals. Frequently clean up the mud and sand on the dust ring of the cylinder dynamic seal and the exposed piston rod to prevent sticking to the surface of the piston rod. Dirt enters the cylinder and damages the piston, cylinder or seal.5. Check the connections of threads, bolts and other parts frequently, and tighten them immediately if they are loose.6. Lubricate the joints frequently to prevent corrosion or abnormal wear in the absence of oil. DetailMany pneumatic high-pressure pumps

DetailAbout marine diesel engines
Marine diesel engines have high thermal efficiency, good economy, easy starting, and great adaptability to various types of ships. They were quickly used as ship propulsion power after they came out. By the 1950s, diesel engines had almost completely replaced steam engines in newly constructed ships. Marine diesel engines have become the main power of civil ships, small and medium-sized ships and conventional submarines. Marine diesel engines can be divided into main engines and auxiliary engines according to their roles in ships. The main engine is used as the propulsion power of the ship, and the auxiliary engine is used to drive the generator, air compressor or water pump.Marine diesel engines are generally divided into high-speed, medium-speed and low-speed diesel engines. The main performance indicators of the three types of diesel engines are listed in the table.The fuel valve test device, pneumatic high-pressure pump, and manual high-pressure pump are the three essential parts of the diesel engine.Marine main engines work under full load conditions most of the time, and sometimes under variable load conditions. Ships often sail in turbulence, so marine diesel engines should be able to work reliably under the conditions of trim 15°~25° and heel 15°~35°. Most ships use supercharged diesel engines, and low-power non-supercharged diesel engines are only used on small boats. Low-speed diesel engines are mostly two-stroke engines, medium-speed diesel engines are mostly four-stroke engines, and high-speed diesel engines have both. The scavenging forms of marine two-stroke diesel engines include backflow scavenging, port-valve DC scavenging and opposed piston port scavenging. High-power medium and low-speed diesel engines widely use heavy oil as fuel, and high-speed diesel engines still mostly use light diesel.Directly drive the propeller, in order to make the propeller have high propulsion efficiency, a lower speed is required. Medium and high-speed diesel engines drive propellers through gear reduction boxes. Gear boxes are generally equipped with a reverse mechanism to achieve propeller reversal, but low-speed diesel engines and some medium-speed diesel engines can reverse themselves. Medium and high-speed diesel engines also realize electric transmission through generator-motor-propeller. When high power is required, multiple engines can be used in parallel, and only one main engine can be used when sailing at low speeds, thereby improving operating economy and reliability. When two main engines are installed on the same ship, they are divided into left and right engines according to the installation position and the steering of the propeller. Detail
