Electronic ignition device for relief combustible gas is a device used in refinery and natural gas gathering station to deal the tail gas and relief natural gas. It is a safe environmental equipment as it can remove the danger brought by the relief combustible gas to the environment.
KOSUN electronic ignition device mainly consists of DN200 (or DN150) gas burner (torch), GDH-2 electric flame igniter, priming apparatus (such as liquefied gas pot, and hose, etc.),and drilling liquid-gas separator (to be matched for drilling engineering).

Jet mud mixer is used to make and mix drilling fluid to change the density and viscosity. This device can satisfy the fluid weighting and mixing of solids control system for 1500m-9000m drilling。 It also is utilized for modest sewage treatment, industrial wastewater remedy and aeration pond.

Decanter centrifuge separates by the work principle of centrifugal sedimentation. The drilling fields usually apply spiral settling centrifuge which works on the basis of different component densities. It mainly removes 2~10μm solid phase from the mud as the last stage in solids control system. It has shared applications in both weighted and unweighted drilling fluids.

A hydrocyclone is most often used to separate "heavies" from a liquid mixture originating at a centrifugal pump or some other continuous source of pressurized liquid. A hydrocyclone is most likely to be the right choice for processes where "lights" are the greater part of the mixture and where the "heavies" settle fairly easily.
The work principle of hydrocyclones is to separate two or several components with different densities with the aid of centrifugal force.

Centrifugal pump has a lot of types, classification method commonly have following several ways
According to impeller number: single stage centrifugal pump, multistage centrifugal pump
1 Single stage pump: there is one impeller on pump shaft.
2 Multistage pump: there are two or more impellers on shaft, and pump total head is the sum of N impeller heads.
According to working pressure: low pressure, middle pressure, and high pressure centrifugal pump
1 low pressure pump: pressure is lower than 100 m water column

A decanter centrifuge operates on the principle of accelerated settling. Particles will settle in a viscous media according to stoke’s low, which in simple form is written as follows:

If a sphere settles in a liquid of known density and viscosity, and the settling rate is measured, then by stokes low the density of the ball or sphere can be calculated if the diameter is known. Or. The diameter can be calculated assuming the density is known.
