RockySea Petro Spiral Drill CollarIn directional drilling, due to the large deviated well and the large contact area between the drill collar and the borehole wall, problems like sticking and jamming are more likely to happen. The spiral drill collar reduces the contact area between the drill collar and the borehole wall, so it is widely used. Spiral drill collars are not listed in intl standards, but due to its practical value, many manufacturers have produced them.Description The function of

VIEW DETAILSRockySea Petro Pneumatic Diaphragm Metering Pump
Pneumatic diaphragm pump is a new type of conveying machinery, which is the most novel pump in China at present. Compressed air is used as the power source to pump out all kinds of corrosive liquids, liquids with particles, high viscosity, volatile, flammable and highly toxic liquids. The pneumatic diaphragm metering pump is a new product developed by RockySea in recent years and is used in various special occasions.
Application
1. Food Processing/Biological Hygiene/Pharmaceutical
2. Chemical Petroleum
3. Ceramic paint
4. Wastewater treatment
5. Chemical buildings/public facilities
6. Automotive Plating & Polishing
Feature
The Pneumatic diaphragm metering pump of RockySea has the following advantages.
1. Suitable for medium and high viscosity fluids.
2. Applicable to places with harsh environment, such as construction sites
3. In the treatment of hazardous and corrosive materials, the diaphragm pump can completely isolate the materials from the outside world.
4. Reliable and low cost pneumatic pump in flammable and explosive environment.
5. The pneumatic diaphragm pump is small in size and easy to move, does not need a foundation, occupies a very small area, and is simple and economical to install.
6. It can be used to transport and measure fluid with unstable chemical properties, such as photosensitive materials, flocculating liquid, etc.
Working principle
The pneumatic diaphragm metering pump is one kind of positive displacement pump whose volume changes due to the reciprocating deformation of the diaphragm. Its working principle is similar to that of a plunger pump
Two symmetrical working chambers of the pump are respectively equipped with an elastic diaphragm. The linkage links the two diaphragms together. After the compressed air enters the valve from the intake head of the pump, it pushes the diaphragms in the two working chambers to drive the two diaphragms connected by the linkage to move synchronously. At the same time, the gas in the other working chamber is discharged from the back of the diaphragm outside the pump.
Once the end of the journey is reached, the valve distribution mechanism automatically introduces compressed air into another working chamber to push the diaphragm to move in the opposite direction, thus forming a synchronous reciprocating motion of the two diaphragms. Each working chamber is equipped with two one-way ball valves. The reciprocating movement of the diaphragm changes the volume of the working chamber, forcing the two one-way ball valves to open and close alternately, thus continuously absorbing and discharging liquid.
