Universal three-screw pump with wide application

Product Features:

1.The screw units is rotating along with the external prime mover.

2.The spiral groove of the screw opens periodically,and the volume of suction cavity increases,resulting into a vacuum.

3.The medium is absorbed into the spiral groove and sealed in the spiral groove.

4.Along with the rotation of screw,the medium moves toward the outlet along the axial line of the screw.

5.The medium is pumped out.This is the operating principle of screw pump.


Heavy oil pump is used to transfer heavy oil coal tar and boost injection combustion. Heavy oil pump is specially designed for deep processing of coal tar.

Heavy oil pumps, heavy oil pumps are suitable for high temperature 200 C impurity resistance, pressure stability, coal tar pump pressure holding time is long and so on. Heavy oil pumps and coal tar pumps have made corresponding improvements in material quality of main components and shaft end seals according to the characteristics of price quality. Heavy oil pumps and coal tar pumps make coal tar pumps more suitable for specific media. The service life of heavy oil pumps is more than 10 times that of the same general gear pumps. Heavy oil pump is a kind of volumetric pump. Its remarkable advantages are simple structure, small volume, high speed, stable and reliable operation, small pressure fluctuation, stable flow, low noise and high efficiency. It is a high viscosity heat preservation screw pump.


Performance  Viscosity:3.0 ~ 1500 mm2/s

Flow:5 ~ 5300 L/min

Maximum Pressure:4.0 Mpa

Maximum Temperature:150 ℃

 

When the triple screw pump is stored or shut down for a long time, it must be protected against corrosion. In this case, both inside and outside of the pump should be protected and sealed, and the effect of protection depends on the position of protection and the storage conditions of the pump.

Usually the pump does not need special protection. If additional requirements arise, special storage of pumps and spare parts can be carried out during the planned storage period as required by customers.

External protection is sprayed by paint or spray gun.

Protection Points: All untreated bare metal or unpainted parts and components.

The protective agent is poured into the pump to achieve the purpose of protection. To this end, first of all, a flange cover is used to seal the suction port of the pump. When filling the pump with preservatives, it is ensured that the discharge port of the pump is higher than the suction flange. At the same time, the pump is driven slowly in the opposite direction of the pump rotation. The filling process must be continued until the protective agent reaches the sealing line of the outlet flange and there are no bubbles. Then close the outlet flange of the pump.
