The workover process of a tubing pump involves first connecting the barrel to the tubing and running it into the well at the desired depth. Then, the plunger is inserted into the barrel along with the sucker rod. Compared to rod pumps, tubing pumps are larger in size when used in the same tubing. This design allows for a greater displacement and simpler structure, making them ideal for shallow wells with high production rates.
The THD type of tubing pump has its standing valve directly connected to the barrel and cannot be removed separately. In contrast, the THC or THM types allow the standing valve to be pulled up independently from the barrel. The seating mechanism of the THC pump is cup-type, while the THM uses a mechanical type. These models are particularly suitable for wells that require frequent workovers.

Whether you're working on shallow wells or need frequent maintenance, there's a model available to suit your needs. With a variety of sizes and configurations, they provide reliable performance under different conditions.
Stereo Light Curing Molding - Sla
STEREO LIGHT CURING MOLDING - SLA
It mainly uses photosensitive resin as a raw material, and utilizes the characteristic that liquid photosensitive resin will cure quickly under ultraviolet laser beam irradiation. The photosensitive resin is generally liquid, and it immediately initiates a polymerization reaction and completes curing when irradiated with a certain wavelength of ultraviolet light (250 nm to 400 nm). SLA focuses on the surface of the light-curing material by focusing ultraviolet light of a specific wavelength and intensity to solidify it sequentially from point to line and from line to surface, thereby completing the drawing of a layered cross-section.
