Product Overview:

This is an explosion-proof self-priming oil pump, which can be used to transport flammable and explosive media or seawater.

It has the characteristics of long service life and smooth operation.

1. Overview of 40CYZ-20 Self-priming Oil Pump Products

The explosion-proof self-priming oil pump produced by the unit is the latest product developed after the relevant technical data is digested, absorbed and improved.

Explosion-proof self-priming oil pump is suitable for the oil industry, oil depot, tank truck and other working conditions, respectively transport gasoline, kerosene, diesel and other petroleum products and sea water, clear water, medium temperature -20℃ ~ 80℃, use corrosion resistant mechanical seal can transport corrosive liquid.

II. Product characteristics of 40CYZ-20 self-priming centrifugal oil pump

1, with simple structure, convenient operation, smooth operation, easy maintenance, long life, and has other pumps do not have the characteristics of self-priming function.

There is no need for bottom valve in the pipeline, and only need to ensure that there is quantitative oil diversion in the pump body before working. When it is used for oil tanker or Marine oil pump, it can also be used as tank sweeping pump with good tank sweeping effect.

2. The pump body is made of high quality stainless steel, the seal is made of tetrafluorine mechanical seal, anti-corrosion and durable, the pipeline does not need to install the safety valve, the suction pipeline does not need to install the bottom valve, so the pipeline system is simplified, and the working conditions are improved.

Use of 40CYZ-20 explosion-proof centrifugal oil pump

I. Preparation and inspection before starting:

1. The oil pumps of this series are lubricated with high-quality calcium butter and No. 10 oil respectively according to their operating conditions. If the pump is lubricated with butter, the bearing box should be filled with butter regularly; if the pump is lubricated with oil, the oil level should be fully added.

2. Check whether the liquid storage in the pump shell is higher than the upper edge of the impeller. If it is insufficient, the liquid storage can be directly injected into the pump body from the liquid filling port on the pump shell.

3. Check whether the rotating parts of the pump are stuck or knocked against.

4. Check whether the bottom foot of the pump body and the nuts at the connection are loose.

5. Check the coaxiality or parallelism of the pump shaft and the motor spindle.

6. Check whether there is air leakage in the inlet pipeline. If there is air leakage, try to remove it.

7. Open the inlet valve, slightly (not fully) open the outlet control valve.

2. Stop the pump

1. First close the valve on the outlet line.

2. Turn off the power to stop the pump.

3. In the cold season, the liquid storage in the pump body and the water in the cooling chamber of the bearing body should be emptised to prevent freezing and cracking of the machine parts.
