CYZ-AtypeSelf priming oil pumpProduct Features

1Self suctionoil pumpIt has the characteristics of simple structure, easy operation, stable operation, easy maintenance, high efficiency, long service life, and has self-priming function that other pumps do not have. There is no need for a bottom valve in the pipeline. Before operation, it is only necessary to ensure that a certain amount of oil is stored in the pump body. Equipped with the function of "one-time drainage, lifelong self-priming", used for oil tankers or shipsoil pumpWhen used, it can also serve as a cabin cleaning pump with good cleaning effect.
2Self suctionoil pumpIt is made of high-quality materials and sealed with hard alloy mechanical seals, which are durable and long-lasting. The discharge pipeline does not require the installation of a safety valve, and the suction pipeline does not require the installation of a bottom valve, thus simplifying the pipeline system and improving working conditions.

CYZ-AtypeSelf priming oil pumpWorking principle and structural description

CYZ-ASelf suction centrifugationoil pumpBoth adopt an axial return pump body structure. The pump body is composed of a suction chamber, a liquid storage chamber, a scroll chamber, a liquid return hole, a gas-liquid separation chamber, etc. After the pump starts normally, the impeller sucks the liquid in the suction chamber and the air in the suction pipeline together, and is completely mixed in the impeller. Under the effect of centrifugal force, the liquid carries the gas to the outer edge of the scroll chamber, forming a white foam belt with a certain thickness and a high-speed rotating liquid ring on the outer edge of the impeller. The gas-liquid mixture enters the gas-liquid separation chamber through a diffusion tube. At this point, due to the sudden decrease in flow rate, lighter gases are separated from the mixed gas-liquid mixture, and the gases continue to rise and be discharged through the pump outlet. After degassing, the liquid returns to the storage chamber and enters the impeller again through the reflux hole. It mixes with the gas sucked in from the suction pipeline inside the impeller again and flows towards the outer edge of the impeller under the action of the high-speed rotating impeller…As this process repeats itself, the amount of air sucked into the pipeline decreases until the gas is completely absorbed, completing the self-priming process, and the pump is put into normal operation. Due to its unique exhaust capability, this pump is able to transport liquids containing gases,No need to install a bottom valve, it has good cleaning function when used on oil tankers.
Some pumps also have cooling chambers at the bottom of their bearing bodies. When the bearing heats up and causes the temperature rise of the bearing to exceed70℃ At this time, coolant can be injected through any coolant pipe joint outside the cooling room for circulating cooling. The sealing mechanism inside the pump to prevent liquid leakage from high pressure to low pressure area is the front and rear sealing rings. The front sealing ring is installed on the pump body, and the rear sealing ring is installed on the bearing body. When the pump has been running for a long time and the sealing ring wears out to a certain extent, which affects the efficiency and self-priming performance of the pump, it should be replaced.

CYZ-AtypeSelf priming oil pumpinstructions

(one).Preparation and inspection work before starting:
1.This seriesoil pumpAccording to the working condition of the pump, high-quality calcium based butter and10Lubricate the engine oil, if
Pumps lubricated with butter should regularly add butter to the bearing box. For pumps lubricated with engine oil, if the oil level is insufficient, add enough grease
It's.
2.Check if the liquid storage inside the pump casing is higher than the upper edge of the impeller. If it is insufficient, it can be directly supplied to the pump body from the filling port on the pump casing
Inject liquid into the pump and do not start it when the liquid is insufficient, as the pump may not function properly and the mechanical seal may be damaged.
3.Check if the rotating parts of the pump are stuck or bumped.
4.Check for loose nuts at the pump body feet and connections.
5.Check the coaxiality or parallelism between the pump shaft and the motor shaft.
6.Check if there is any air leakage in the inlet pipeline, and if there is any, try to eliminate it.
7.Open the valve of the suction pipeline and slightly open (not fully open) the outlet control valve.
(two).Stop pump
1.Firstly, the gate valve on the discharge pipeline must be closed.
2.Stop the pump from rotating.
3.In the cold season, the liquid stored in the pump body and the water in the cooling chamber of the bearing body should be emptied to prevent freezing and cracking of the components.
