API SHAKER SCREEN

Mud Cleaner for sale system,See Drawing 7 for wiring diagram of Model LW455-842N and LW355-1250N Mud Cleaner, Model LW600-945N’s and varispeed centrifuge’s is in another book, star-delta starting is adopted in this kind of centrifuge, but other principle is the same as Model LW450-842N. start-up order is: Auxiliary motor-main motor-motor of mud filling pump. You must start the machine in this way, otherwise no act take place, stop order is: motor of mud filling pump- main motor 5 min. later Auxiliary motor. 1. Installation, Mud Cleaner Instruction: 4.1 Installation Attached Drawing 1 is structure and Installation schematic diagram of the centrifuge 4.1.1 In order to fully mix recovered liquid, centrifuge should be installed on the top of No.2 tank or any other suitable place, horizontally and firmly. This is most important for recovering charged materials from charged mud. 4.1.2 The four legs of the centrifuge support should be mounted on hard-steel tank’s surface. Please lay channel iron(≥14#) on it if the surface is too mild, then mount the support’s legs on the channel iron. 4.1.3 Sand discharged groove should be popped out of the tank, and water supply pipe should be joined with the groove. The overflow opening of the centrifuge flows vertically to the reflux flume, underflow opening must have a slant of more than 60° in order to ensure that mud is drained off from the centrifuge smoothly. 4.1.4 Mud filling pump should be mounted on a proper position at the back of the sand-desander and slurry-desander, then connect the mud supply hose and mud-feed pipe by a union. 4.1.5 Connect the flushing lines and split-flow lines on mud-feed pipe and box body. 4.1.6 Power switching box should be installed for the centrifuge control system. Forbidden to connect the mains with the control box directly so as to ensure safety. 4.2 Debugging of the centrifuge 4.2.1 Remove any debris which may affect centrifuge running. 4.2.2 Check the strain of the band. 4.2.3 Rotate the pulley of main motor Mud Cleaner manually, check if any obstruction exist between rotating bowl and box or feed pipe ,remove the obstacles if any. 4.2.4 Start auxiliary motor, at the same time, fill some fresh water into the centrifuge through flushing adapter, then run for one minute. because centrifuge has been analogue status tested before delivery, so a thin layer of wall cake which can’t be discharged is stuck on the inner surface of the drum. Part of wall cake will peel off because of vibration during transportation, lead to unbalance of the drum. Serious vibration even stop(caused by main motor’s thermal protection) will occur if you start main motor to rotate in high-speed now. Fill some water in and rotate the auxiliary motor, then peeled wall cake will be soaked and redistributed, and vibration will be eliminated when starting the centrifuge for the first time. The same work should be done if the Mud Cleaner hasn’t been used for a long time,you can refer to here to visit.

The smaller particles, with smaller centrifugal force, cannot be tossed to the inner wall of the Decanter Centrifuge, will be discharged from the overflow pipe with the upward movement of the liquid.

Therefore, inlet pressure is stable at 0.21-0.35 is the necessary and sufficient conditions for a normal work of the shale shaker. try to make the sand pump outlet pressure stabilize in this scale, reducing the underflow hole diameter, the cyclone pressure will larger; otherwise the pressure drop.

But too large proportion of the Desander will accelerate the wearing of sand pumps and cyclones while too small proportion will affect the purification efficiency. Because the centrifugal force and quality is proportional to the speed of the square circle, the heavier particles are tossed to the inner wall of the cyclone under the centrifugal force, then move down to the sand-discharge nozzle.

GNPS752 shaker screen operation and maintenance instruction 1. Summarize 2. GNPS752 Mud Cleaner structure 3. GNPS752 Mud Cleaner technical parameters 4. GNPS752 features 5. Lifting, transportation and installation 6. Operation on Mud Cleaner 7. Mud Cleaner Maintenance 8. Spare parts for GNPS752 9. Enclosed files for GNPS752 1. Summarize Shale shaker GNPS752 is high efficiency shaker. It is designed according to users’ actual demand based on modern technique and principle. GNPS752 takes advantage of double vibration motors in-phase principle. It holding ideal design on structure, and work steadily, operated lasting time without any problem, take rather little cost on maintenance. If choose proper model or parameters, it can work for many kinds of drilling fluid solids control. It is an ideal solution for Oil and gas drilling, HDD, Metallurgy, mining tail mud solids control 2. GNPS752 shale shaker screen structure Please find GNPS752 shaker structure as fig I. It contains pedestal, shaker deck, tension wedge, shaker screen, rubber strip, deck adjustment device, baffle box, tension device, electric cabinet, vibration motor, damping spring. Shale shaker GNPS752 can be used by single or designed as tandem and triplex shaker to be operated at drilling job site 3. GNPS752 Mud Cleaner technical parameters Model: GNPS752 Vibration: Balanced elliptical motion Vibration amplitude: 7mm (double type) Motor power: 1.0+0.4 kW Treating capacity: 25L/S Screen area: 1.35m2 Screens: 750×900，10~150 mesh (Frame screen or Pyramid frame screen) Dimension: 2037×1525×1112mm Weight: 1100kg Resource Box : The author of the article recommends Mud Cleaner pls click here to know.

There are 3/4〃 gas-discharge ball valves at the top of the overflow pipe.  the valves are used to prevent the overflow pipes from siphon phenomenon. It should be halted when start up the desander. And it should be keep open while the machine is working normally.

Normal operation Debugging of the desilter cyclone：make sure the capacity effect of the cyclone by debugging the inlet pipe pressure （0.20-0.40Mpa）. Caution: a stability inlet pipe pressure is an important condition for the normal operation of cyclones.

Cyclones with different specifications under different inlet pressure are corresponding to a certain separating scale and separation efficiency. When the proportion of the mud is changing, the larger the inlet pressure, the larger capacity to mud treatment, and the smaller separation particles.
