Product details

The CYZ-A self-priming pump is an ideal product for the petroleum industry, land oil depots, and tank trucks. It is also suitable for use as a cargo oil pump, bilge pump, ballast pump, and machine cooling water circulation for transporting petroleum products such as gasoline, kerosene, diesel, and aviation kerosene, as well as seawater and clean water. The medium temperature ranges from -20 ℃ to 80 ℃. If transporting chemical liquids, corrosion-resistant mechanical seals can be used instead.

Advantages of CYZ-A self-priming oil pump

1. The CYZ-A self-priming oil pump 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. Used for oil tankers or transportation
When on a water vessel, it can also serve as a tank cleaning pump with good cleaning effect.
2. It is refined using 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.
3. The oil pump is suitable for transporting various oils, such as heavy oil, diesel, and lubricating oil. It is equipped with copper gears to transport low point liquids, such as gasoline and benzene. Our unit also produces stainless steel gear pumps that can transport beverages and corrosive liquids.
4. The CYZ-A self-priming oil pump can also be applied to those containing hard particles or fibers, and is suitable for various viscosities. The temperature can reach up to 300 ℃. If you need to transport high-temperature liquids, please use a high-temperature resistant gear pump, which can transport liquids below 300 ℃.
5. The CYZ-A self-priming oil pump has multiple pump types with simple and compact structures, easy to use and maintain, and good self-priming performance, which helps to prevent the need to inject liquid before each pump start.
6. Some oil pumps achieve lubrication automatically through the conveyed liquid, so there is no need to add additional lubricating fluid during daily operation.
7. The CYZ-A self-priming oil pump uses an elastic coupling to transmit power, which can compensate for small deviations caused by the installation of the oil pump. When subjected to inevitable hydraulic impact during pump operation, it can provide improved buffering effect.

CYZ-A self-priming oil pump structural type

Adopting a pump body structure with the same axis for liquid return, the pump body consists of a suction chamber, a storage chamber, a vortex chamber, a liquid return hole, a gas-liquid separation chamber, etc. The pump's bearings adopt single row radial ball bearings. Some pumps have cooling chambers at the bottom of their bearing bodies. There are sealing rings in the high and low pressure sections inside the pump. The shaft end adopts mechanical seal.

CYZ-A self-priming oil pump requires use

（1） Preparation and inspection work before starting CYZ-A self-priming oil pump:
1. According to the working and operating conditions of the pump, high-quality calcium based butter and No. 10 engine oil should be used for lubrication. If a butter lubricated pump is used, butter should be regularly added to the bearing box. If an oil lubricated pump is used, the oil level should be sufficient
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 are stuck or bumped.
4. Check for loose nuts at the base of the body and at each connection point.
5. Check the coaxiality or parallelism between the shaft and the motor spindle.
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.
