What should be paid attention to in the installation and use of shear pump
shear pumpWhat should be paid attention to in the installation and use of? one of the pumps required when handling shear pump drilling fluid. Applied to solid-liquid separation system to improve the performance of drilling fluid, then, let's understand what should be paid attention to in the installation and use of shear pump!
1 )shear pumpInstallation
The shear pump is installed on the same base as the motor, but when the user uses it, he only needs to install the whole on the pry bar of the drilling fluid tank. Basic level, reliable, avoid vibration.
Make the installation position of the pump as close as possible to the shear tank, shorten the length of the suction pipe, and reduce the suction loss.
2) Use of shear pump
Before starting the shear pump, please check the wiring of the power supply so that the direction of rotation of the shear pump is consistent with the direction of rotation indication attached to the shield.
Open the valve in front of the pump suction port, fill the pump with liquid, loosen the exhaust plug, discharge the air in the shear pump, and prepare to start.
It is strictly forbidden to use centrifugal pump to pump the active drilling fluid, so as to prevent the solid particles and barite in the drilling fluid from damaging the shearing impeller. It is strictly forbidden to run the cut-off pump by air. On the one hand, idle running accelerates the wear of the shear impeller. On the other hand, many shear pumps use mechanical seals. Airrunning will aggravate the friction pair wear of the mechanical seal and disable the shear pump shaft seal.
Turn on the shear pump and add polymer chemicals such as polymer and clay through the shear mixing funnel. Quickly hydrolyze with drilling fluid gun to make it uniform. The fluid containing the polymer and clay is fed into the drilling fluid system using a shear pump. When stopping the pump, close the valve at the suction port. In winter, the liquid of the volute and the decompression cover of the centrifugal pump must be pumped out to prevent freezing and cracking.
shear pumpIt is a new type of product designed and manufactured according to the actual production requirements of the lubricating oil and grease industry. It is mainly suitable for the transportation and shearing of lubricating oil and grease in the processing technology of lubricating oil and grease. It is an ideal transportation and pressure equipment for lubricating oil and grease industry.
The main working parts of the shear pump are composed of stator and rotor. Under the action of centrifugal force and hydraulic pressure, the stator performs strong shearing, centrifugal extrusion, impact crushing, liquid layer friction, uniform turbulence and other comprehensive effects on the material, so that the non-phase solid phase, liquid phase, gas phase and other media can be uniformly circulated in an instant, making the original product a stable high-quality product.
Shear pump is also known as homogeneous pump, emulsion pump, mixing pump, and pump, which has a high shear type emulsion pump, also known as high shear type homogeneous pump. In the high-speed operation of the motor, the material moves at high speed in the very narrow gap between the rotor and the stator. Under the action of mechanical movement and centrifugal force, the material is uniformly mixed by high-speed shear, and then ground and crushed, stirred and emulsified. The equipment has strong transportation capacity, good mixing and emulsification effect, less investment and quick effect. It is one of the indispensable equipment in the current mixed transportation process. The conveying capacity is about 0.3MPa.
