Product overview

KZJ series slurry pump is a single-stage single-suction cantilever centrifugal pump, is my company according to the market demand, to comprehensively consider the working characteristics of the specific application system, to absorb the advantages of similar products at home and abroad, developed a new generation of slurry pump. This series of pump adopts excellent hydraulic model design, ensure the pump is more efficient, more reliable operation, longer life, the various performance indexes exceed industry standards, in the domestic leading level.

Application field

Mine: pulp; Metallurgy: slurry, slurry

Coal ash, mortar; Building materials: including sediment pulp

Chemical industry: pulp; Water: sand, gravel, mud

Product features

1, CFD fluid analysis and design, hydraulic performance is good, for the closed impeller impeller, high efficiency, wide flow design, anti-clogging, good resistance to cavitation performance.

2, over-current components are all metal high hardness, abrasion resistant materials, excellent wear-resisting corrosion resistance

3, special rotor axial regulating mechanism, ensure the long-term stable operation of pump in the best condition

4, a variety of sealing type: vice impeller combination + packing seal and mechanical seal arbitrary choice

5, adopted the bracket, short cantilever, the large capacity fuel tank, such as reliability design, the whole machine trouble-free working time increased significantly

6, the thin oil lubrication and reasonable water cooling system, greatly extend the bearing uptime

The working conditions

Discharge aperture: DN = 40 ~ 300 mm; Traffic: Q = 30 ~ 2000 m3 / h. Head: H = 15 ~ 130 m

Medium temperature: 80 ℃ or less commonly, special can reach 110 ℃; Medium concentration: mortar concentration of 45% or less pulp density 60% or less

Mode of transmission: general for direct drive, also can be changed to the rest of the drive way according to the requirements of customers.

Q:What is a positive displacement pump? He Weizheng displacement?
The principle and structure of displacement pumps are similar to those of hydraulic motors. Positive displacement is the pump outward to provide flow and pressure, that is, conventional pumps. A negative displacement pump is a hydraulic motor that rotates by external pressure and flow
Q:Metering pumps related matters
Rotate to stroke length 100% position. This allows the kit to rotate to the back of the drain hole and align the bottom of the pump. Adjust the hydraulic end and diaphragm to the proper position during the pump operation.The duration of the pulse may not be long enough for the reaction time. With respect to the standard pulse width 80msec, the flow monitor pulse width expansion can be activated, increasing the pulse width to 300msec. Activate the smart switch, remove the cover fixed circuit board, remove the jumper X-1. This activates the extended function and allows more time before the failure instructions.Metering pump installed from the exhaust pump head, the use of self suction liquid imbibition. Keep the suction line as short as possible.
Q:What are the characteristics of a pipe shield pump?
Two, reverse circulation type of shielding pump, its bearings, lubrication, cooling and motor cooling fluid flow direction and the basic type is the opposite. The main characteristic of reverse circulation pump is that it is not easy to generate cavitation. It is suitable for conveying liquid which is easy to vaporize. Sometimes it is also called "easy to vaporize" type. Three, high temperature medium temperature of up to 450 degrees. The cooling water jacket is usually added outside the shielding motor, and a cooling sleeve is added to the outer circulation pipe to cool the high temperature circulating liquid to reduce the temperature of the motor and the bearing. In the case of less power, some manufacturers do not use cooling liquid, but the outside of the motor is equipped with fins and the special winding to adapt to the working conditions, the use of temperature generally can not exceed 400 degrees.
Q:Why does the centrifugal pump start with a closed valve and the axial pump starts with an opening valve?
The power of axial flow pump decreases with the increase of flow rate, and it is a steep curve, so the centrifugal pump starts with an open valve.
Q:Roots pump and dry pumpRecently, the work involved in the vacuum pump, do not understand this, is a ads602 vacuum pump
The front stage pump to a certain pressure to start the roots pump, roots pump has advantages of is at the entrance of low pressure gas pumping speed is high, popular point is in high vacuum pumping speed is still relatively large. With the former pump can achieve different limit the vacuum is different.
Q:Which nuclear submarines use the shaftless pump technology?
Shaftless pumping technology and Simulation of shark skin technology are all the next generation of submarine propulsion technology. At present, there is no submarine in the world.
Q:What are the starting and stopping procedures for centrifugal pumps?
Operation method and operation procedure of self-priming centrifugal pumpClick number: 440 release time: 2011-7-24Centrifugal pump method, centrifugal pump operation steps, centrifugal pump use steps
Q:What are the meanings of the vacuum pump, the front pump and the main pump?
The main pump can be understood as a booster pump, used to improve the vacuum mechanical pump with pumping quantity. As the roots pump, diffusion pumps, molecular pump. These can not use (too much pressure) so the need for mechanical pump drainage, the vacuum chamber is pumped into the rough vacuum, then the main pump starts to work.
Q:What are the advantages and disadvantages of the pump control system and valve control system in the hydraulic system?
Valve control system is generally used for open systems, through the proportional valve or servo valve flow changes to control the motor or cylinder actuator action. The advantages of the system are energy saving, heat generation, and control accuracy. The disadvantage is that the system is complex and the cost is higher.
Q:Why adjust the centrifugal pump outlet valve can adjust the flow?
The centrifugal pump at a fixed speed, the head is fixed, adjust the outlet valve to adjust the diversion area
