Overview

Product Details

The CYZ-A self-priming centrifugal oil pump produced by our unit is a pump product developed through digestion, absorption, and improvement based on relevant technical data at home and abroad. This self-priming centrifugal pump is an ideal product for the petroleum industry, land oil depots, and oil tankers, and is suitable for use as a marine cargo oil pump, bilge pump, fire pump, ballast pump, and machine cooling water circulation. It is used to transport petroleum products such as gasoline, kerosene, diesel, and aviation kerosene, as well as seawater and clean water, with a medium temperature of -20 ℃ to 140 ℃. If transporting chemical liquids, corrosion-resistant mechanical seals can be used instead.
Product features of CYZ-A self-priming centrifugal oil pump:

This pump belongs to the self-priming centrifugal pump, which has the advantages of simple structure, easy operation, stable operation, easy maintenance, high efficiency, long service life, and strong self-priming ability. 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. When used on oil tankers or water transport vessels, it can also serve as a cleaning pump with good cleaning effect.
This self-priming centrifugal pump is refined from high-quality materials and sealed with a hard alloy mechanical seal, which is durable. 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.

Instructions for using CYZ-A self-priming centrifugal oil pump

（1） Preparation and inspection work before starting:
1. This series of oil pumps uses high-quality calcium based butter and No. 10 engine oil for lubrication according to the working and operating conditions of the pump. 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 whether the rotating parts of the pump are stuck or bumped.
4. Check if there is any looseness in the nuts of the pump body feet and various 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.
（2） Stop the pump
Firstly, the gate valve on the discharge pipeline must be closed.
2. Stop the pump from rotating.
During 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.
