Frame shaker screen

Frame shale shaker screen is a familiar oil shaker screen, it is mainly made of steel frame and in the framework of combining two or three layers. The frame stainless steel net cloth frame is made of high strength square steel tube or steel flat to weld, it has several strengthening support bar, the mesh can combined with frame by metal plate or directly bond to the frame. every screen can attach the special rubber stopper to repair the screen damage. Our manufacturer  can produce the size of various specifications according the requirements of customer’s.

Hook strip soft screen

The structure of hook strip soft screen is same as the flat screen, usually it is made of two or three layers stainless steel net cloth close bonding as one. The effective filtration area is bigger than plate screen and the price is lower, but the service life is short, it needs according the different drilling conditions to choose the different screens. Our manufacturer can produce the size of various specifications according the requirements of customer’s.

Wave shaker screen

The surface of wave shaker shaker screen is the unique wave, installation type can be hookstrip or the wedge pressure device of frame. The effective filtrate is 125% to 150% of the same specification of flat screen, so the throughput is increased. Our manufacturer can produce the size of various specifications according the requirements of customer’s.

Flat shaker screen

Now flat shaker screen is the most famous oil shaker screen, it can widely used in different conditions drilling works. The product is made of two or three stainless steel net cloth to bond in the metal scaleboard. At the same time, the screen attach the special rubber stopper to repair the screen damaged, it can effectively save the times and decrease the cost. Our manufacturer has the rich production experience and mature technology, we can produce the size of various specifications according the requirements of customer’s.

High frequency frame shaker screen, drilling fluid shaker screen, all adhesive laminated screen: the product is the easy loss in drilling fluid shale shaker equipment, the contact are of the hole metal flat and screen cloth is painted the organic multicomponent anti-corrosion binder to form the bonding layer, make the screen cloth and hole flat became one, consist of all adhesive laminated screen component.

using the screen overcomes the easy loss factor of now hookstrip laminated screen, make shaker cloth keep in three dimensional fixed condition, and there is not stress concentration condition in the screen, the drainage rate is improved above 20% of now hookstrip screen.

The cost of the product is low, easy to install and dismantle, the drainage rate is big, degassing effective is good, using service life is long and ect. advantages, it is the ideal accessories of shale shaker.

Representative mode shape of screen surface

The common elliptic mode shape

Because the mode shape is fixed exciter on the directly above of the screen box and each locus of import and export moth is round, but the long shaft of elliptic is intersection on the above of screen. The particle moving is good in the export of the screen, but because of the long shaft of elliptic locus in screen export month is tilting, make the speed of drilling cutting is decrease and it is difficult to jump out of the screen, even appearing drilling cuttings accumulation phenomena. Drilling cuttings accumulate increase the through screen opportunity of drilling cuttings, make the solid phase content is increase, if extending the screen, it maybe flow back.

Round mode shape

Because the installation location of exciter in the center mass of screen, the resultant of exciter and mechanical spring according screen center mass. So all mode shape are all approximate round. The normal and crosswise of this kind of shale shake is equal. Screen surface can be installed level, drilling cuttings don’t have accumulation phenomena on the screen surface, it can increase the throughput. In addition, because drilling cuttings are casted to up, but the distance of transportation direction is short, so the speed of the sand transport is slow.

Translation linear mode shape

Each dot of screen box do linear motion, the screen surface is also can installed level, the screm surface has the high speed of solid phase particles transportation, on the screen surface don’t has drilling cuttings accumulation phenomena. Only the vibration direction is reasonable, it also can increase the throughput, this method is widely used in foreign, this is a good mode shape.

Translation elliptic mode shape

Translation elliptic mode shape combined advantages of the round shale shaker and linear shale shaker. Because the elliptic long shaft is inclined to export month direction of shale shaker, each point motion rules are the same, but the transverse amplitude of this kind of mode shape is bigger than vertical amplitude.

Well drilling mud Chinese shale shaker screen

The importance of the screen

The combination property of the drilling fluid shale shaker reflect the sieve size is fine, using life is long and the throughput is big, this conditions are related to the structure and performance of the screen. The screen is a important part of screening task, it is the consumables in drilling fluid, the size of the hole determines the size of the solid phase particles are removed by the shale shaker. Because drilling fluid have corrosive, abrasive resistance and the high temperature,

The specification of the screen

The specification of the screen determines the sieve size, the sieve size is the size of the sieve pore which the particles can pass. Because the oilfield and the related industries learn from the foreign stander, so use the mesh representative the size of the sieve pores, it is said that the number of the sieve pores in one inch width.

For different drilling mud equipments manufacturer will hold their own model

In order to remove the smaller particles in drilling fluid, the material of the screen is the stainless steel wires of the heat treatment, the material of the ancillary shoring structure is steel plate, galvanized sheet, plastic board and ect.

shale shakers. Different type shale shaker will hold different features and superiority.

To develop both precise and accurate process control, DC conducted a battery of tests. These tests included; cure tests by varying time and temperature; bonding strength tests by testing the tensile strength of the cure screens through destructive testing; and chemical exposure tests by immersing a series of screens in chemicals characteristic of the oil & gas industry.
