The characteristics of mechanical seals are that they can be used for various equipment, especially equipment such as reactors and pumps. Because such equipment has high sealing requirements and cannot enter impurities, it is used more. The problem of water leakage is really worrying. Water leakage causes the sealing effect of the seal to deteriorate. This is something that many people shy away from. The following five tricks can help you easily solve the problem of leaking seals:

mechanical seal

Reasons for water leakage of mechanical seals:
1. The equipment is too tight. Check the dynamic ring plane of the mechanical seal. If there is a seriously burnt appearance, black plane, and deep marks, the mechanical seal rubber of the pump becomes hard and loses elasticity. This appearance is caused by the over-tightening of the equipment.

2. The equipment is too loose. Check the plane of the dynamic and static rings of the mechanical seal. There is a thin layer of scale on the surface, which can be wiped off, and the surface is basically free of wear. This is caused by the loss of elasticity of the spring and the poor equipment or the axial movement of the motor.

3. Poor water quality. Due to poor water quality, the cartridge-type mechanical seal is rich in small particles and the content of hydrochloride in the medium is high, and the plane or strained surface of the abrasive-wearing mechanical seal has the appearance of grooves and ring grooves.

4. Water shortage operation constitutes dry grinding damage. This phenomenon is more common in the negative pressure at the inlet of the bottom valve type equipment, there is air in the water inlet pipe, and there is air in the pump cavity. After the pump is turned on, the friction of the mechanical seal produces a high temperature during high-speed operation, and cannot be cooled. Check the mechanical seal and the spring tension is normal. , the contact surface is scorched and blackened, and the rubber hardens and cracks.

5. Cavitation. Cavitation mainly occurs in hot water pumps. Since the medium is hot water, the water temperature is too high to generate steam, and the steam in the pipeline enters the high part of the pump cavity. This part of the steam cannot be cleaned, and then constitutes a water shortage operation, the dry grinding of the mechanical seal fails, and the cavitation device automatically discharges. Air valve, switch.

The solution to the leakage of mechanical seals:
1. Disposal method: Adjust the height of the equipment. After the impeller is installed, pull the spring with a screwdriver. The spring has a strong tension.

2. Adjust the height of the mechanical seal and the return spring.

3. Improve water pressure or medium, switch the seal.

4. Drain the air in the duct and the pump cavity, and exchange the mechanical seal.

5. Do not use hot water as much as possible.

Leakage of mechanical seals is not a trivial matter, and it will lead to failure if you do it wrong, so you must find the cause in time when you encounter this problem. Don't litter. There is also the use of seals under the right conditions. And keep the water clean.

When installing a deep well submersible pump, you need to pay attention to the installation steps. Only by following the relevant steps step by step can the pump operate normally underwater. So what are the installation steps of the deep well submersible pump? The editor of SEAKOO will introduce it to you through the article.

Deep well submersible pump

1. Before installing the deep well submersible pump, check whether the power supply voltage meets the specified use standards of the deep well submersible pump.

2. The diameter of the deep well should be slightly larger than the outer diameter of the deep well submersible pump unit, and the actual depth of the well should be measured before installation.

3. Check whether the good platform is suitable for installing the well cover and whether it can bear the weight of the deep well submersible pump unit and the supporting water outlet pipe.

4. Check whether the deep well submersible pump unit is well assembled, and remove the filter screen of the deep well submersible pump before installation.

5. Use a multimeter to check whether the three-phase wires of the deep well submersible pump are connected and whether the DC resistance is approximately balanced.

6. If the protection switch and control cabinet equipment are connected well, the soft-starting step-down control cabinet must be selected if the equipment is of high power. Recommended reading: Long-axis deep well submersible pump models and parameters

7. Install the rubber gasket of the water pipe to be upright, and evenly tighten the bolts without the water-saving pipe.

8. During installation, the cables, and the water pipes should be fastened with plastic tapes or water-resistant ropes on each section of the water pipes.

9. For the installed deep well submersible pump, check the insulation resistance and the connection of the three conductors from the switch in turn and then check the instrument and starting equipment.

10. After the deep well submersible pump runs for the first time for four hours, stop and quickly measure the thermal insulation resistance.

11. After the pump is stopped, it should be restarted after an interval of ten minutes. Do not start frequently to avoid damage to the motor and pump parts.

12. During use, it should be checked regularly. If the following phenomena are found, the machine should be stopped immediately, and then run after troubleshooting.

13. For the products packaged separately by the deep well submersible pump, when assembling and assembling, remove the check valve body of the pump part, and wipe the stop part of the pump connection.

14. The deep well submersible pump should be repaired outside the deep well once a year. Read more: How to install submersible pumps for wells

The above main steps are about the installation steps of the deep well submersible pump. Of course, during the installation, it is still necessary to have the technical support of the installation manual of the relevant enterprise or the relevant technical guidance and to provide more comprehensive guidance for the specific deep well submersible pump, in order to make the Normal installation for deep well diving. As a deep well submersible pump manufacturer in China, SEAKOO provides deep well submersible pumps with stable performance and long service life.
