Product Description:

1. Structure of Shear Pump of Type JQB Description


Shearing pump can mix and process the mud quickly, which can meet the requirements of making mud with high performance. With shearing pump, the mud mixing time can be reduced and the economic benefit of drilling can be improved.


It is used to shear the polymer and clay in the drilling fluid, improving mud performance and decrease "fish eye" which will bring down the in-place permeability and hydrocarbon reservoir production.


Shearing pump applies axial suction stucture, consisting of motor,pump seat, pump shell, impeller,shearing impeller and other components. 


Vee belt and mechanical compound seal guaruantee no leakage. There is a stainless turbine inside(which composes entrance bucket, main impeller, nozzle,catch compartment)and a shearing plate.


2. Main Features of Shear Pump of Type JQB


Shearing pump features: Improve the hydration extent of particles greatly;Save betonies above 30%;Shear, dilute and hydrate the polymer as soon as possible.; Provide a bigger discharge and lift, which satiosifies the requirements of making and processing mud;little mud cake and liquid lost; special shaft seal design; reliable sealing and convenient operation as well as maintenance.

Q:What is a vacuum pump for?
Aquaculture, screen printing machine, photographic plate machine, injection molding machine, automatic feeding machine, paper transport...
Q:How to install, operate and maintain the pipeline booster pump?
When the pump leaks, check it immediately to prevent leakage. If it leaks with the motor connection, replace the mechanical seal. Check that the power is connected. Is the supply voltage consistent with the operating voltage of the pump?. If the above a and B are normal, please remove the pump, open the pump cover, remove the foreign body in the pump, and then pump the lid on, and then tighten it to normal.No water pump, pump installed in the tap water pipeline, such as tap water level in the pump impeller on the plane (horizontal installation) or center line (vertical) below, you should turn off the power supply, to tap water level rise more than the impeller plane or the center line, connected to the power supply, to avoid mechanical damage (automatic no need to turn off the electric type). When the pump used in pumping wells, please check whether the water inlet pipe leak; pump cavity storage is not enough, should be filled with water, whether the suction process is too high, proper adjustment. Check whether the inlet and outlet diameter is too small or blocked. Automatic type after a period of time, there may be automatic failure phenomenon, mainly stainless steel and other metal products in pipes, long-term precipitation to shut off the power supply after unloading, unscrew the top screw, remove the plastic sheet to be cleaned, and then, according to the original reset, the normal debugging, can be re used.
Q:What is the relationship between the minimum suction vacuum of a pump and the required cavitation?
Suction is allowed to pump the vacuum from the distance from the inlet, which is part of the field installation.The manufacturer of cavitation allowance is closely related to the design and process of pump. Estimation formula: cavitation allowance =10.33 meters - allow suction of -0.5 meters (safety).
Q:What are the parts of a pump? How do you classify it?I just want to know
The liquid ring pump: pumping air, the working medium is generally at room temperature water gas lift pump: simple structure of submersible sewage pump: a form of basic principle, performance parameters of centrifugal pump, with it the same. Underwater installation, sound, water cooling condition, screw pump: spiral lower invasion water medium variety formThere are too many kinds of pumps, such as submersible pumps for wells, centrifugal feed pumps, sewage pumps, etc. the submersible pumps are wet, oil immersed, etc.The water pump for automobiles is divided into oil lubrication and grease lubrication,
Q:Common failure treatment of piston pump
Table 15 common troubles and treatment of hydraulic pumpsFault phenomenon, x09 cause analysis, x09 elimination method(1) the pump does not carry oil; the x091. pump does not turn x09 (1); the motor shaft does not rotate1) missed connection power supply2) electrical wiring and component failure, x09 check electrical and troubleshootx09x09 (2) motor heating trip
Q:How is the pump level of submersible sewage pump determined?
Generally as:The bottom elevation of sump sump plus 300 is the water level of pump stopThe top 300 of the sump top elevation is the pump water level
Q:What happens when a centrifugal pump is selected?
First of all, the performance curve of the centrifugal pump is similar to the track of the train, and the train can not run away from the track.Secondly, the performance curves of centrifugal pump mainly include flow head curve, efficiency flow curve, power flow curve. When the pump is ready, the curve is fixed. In practical application, after determining the flow rate, the corresponding lift head, efficiency and power (relative to density) are determined. General requirements for centrifugal pump operating in the vicinity at the highest point of efficiency, the efficiency of the flow curve is similar to parabola, so if the actual operation condition deviated from the rated point, whether large or small, will cause the decline in pump efficiency (generally rated value is less than 15%), increased operating costs.
Q:The suction pump has a nominal suction range of 30 metersHow deep can a well be sucked?Well, sixteen meters,
A standard atmospheric pressure can be 10.33 meters to 30 meters of water, suction is atmospheric pressure there are three standard atmospheric pressure so high? This is impossible in general, remove the vaporization removed 0.5 meters critical yo,
Q:The function of centrifugal pump
6. Stuffing box mainly consists of packing, water seal ring, stuffing box, packing gland and water seal pipe. The function of the stuffing box is mainly to close the gap between the pump shell and the pump shaft. The water in the pump is not allowed to flow outside and the outside air is not allowed to enter the pump. Always keep the vacuum in the pump! When the pump shaft and packing friction heat, it is necessary to rely on water seal to control water into the water ring, so that the filler cooling! Keep the pump running properly. Therefore, in the water pump running inspection process, the stuffing box inspection is to pay special attention to! In the operation of about 600 hours, it is necessary to replace the packing.
Q:What are the causes of pump shock?
3. the water pump set screws loose, adjust the concentric, fastening the foot4. pump into foreign body, open cover overhaul5. the flow is too large or too small, adjust the equipment to control the water output
