Product Description:

Production Introduction:
This model of pump is vastly used for aquariums, mine enterprises, gardens, family spray and irrigation, watering flowerand flush. It is characterized with compact sizes, light weight and convenient use. The float switch can automatically control on and off without people’s supervision. It is also equipped with 1-phase capacitance-operation asynchronism motor.or 3-phase asynchronism motor, the protector in which can automatically cut off the power when it overheat or overcurrent, thus guarantee the security and reliability of pump’s operation even in the atrocious environment.

Function and feature:
Model QDX(P) Stainless steel casing submersible pump is vastly used for aquariums, mine enterprises, gardens, family spray and irrigation, watering flower and flush. It is characterized with compact sizes, light weight and conbenient use. The float switch can automatically control on and off with the chage of water level. It is also equipped with 1-phase capacitance-operation asynchronism motor, or 3-phase asynchronism motor, the protector in which can automatically cut off the power when it overheated or overcurrented, thus guarantee the security and reliability of pump’s operation even in the atrocious environment.

Condition of usage:
1.The depth of the electrical pump below the water is no more than 5m;
2.The temperature of the water is no higher of 40*C ;
3.The PH figure of the water is between 6.5-8.5;

Q:Hydraulic pump displacement refers to the pump shaft what?
Just as you carry a spoon to the water. How much water can you pump at once (every turn)? That's the displacement.
Q:Filter backwash pump for what use, what is the principle of work ah?
Regeneration of the filter medium is required to regain the filtration capacity of the medium. The regeneration process is mainly accomplished by the backwashing pump (the backwash pump is not a special pump, referring to the pump for the completion of the process). The working principle is through the cleaning liquid from the downstream of the filter into the backwash pump (alkali, acid and water), reverse flushing filter medium, cleaning liquid discharged from the upstream, this process can be attached to the dielectric surface and internal impurities washed away.
Q:What are the problems that should be paid attention to when using vacuum pumps?
(8) in the process of running the pump, the bearing temperature shall not exceed the ambient temperature 35C, and the maximum temperature shall not exceed 80C.(9) if the abnormal sound of the vacuum pump is found, the reason should be stopped immediately.(10) vacuum pump to stop using, first shut down valve, pressure gauge, and then stop the motor. (11) vacuum pump in the first month of work, 100 hours after the replacement of lubricating oil, oil every 500 hours after the change.(12) adjust packing gland regularly to ensure the normal condition of drip in packing room. (13) regular inspection of shaft sleeve wear, larger wear should be replaced in good time.
Q:Metering pumps related matters
2) change the metering pump diaphragmTrouble is often encountered when the old diaphragm is removed. Provide some additional advice on how to remove the old diaphragm.After in the pump head loose, remove the pump head before the stroke length adjustment to the 10% position. To ensure that the electromagnetic axis has sufficient pressure to maintain its connection firmly, so that you can unscrew the diaphragm.The pull end torque from the Jack out of the screw. Seize the liquid counter clockwise rotation. There is a slight resistance that can unscrew the diaphragm.Chemical 3 measurement may end in fluid crystallization, resulting in a one-way valve ball and seat valve does not work.In the end inhalation metering pump may have a gas leak. Hydraulic end suction side connector may lack O ring or suction valve connection loose.3) flow monitoring and measurement of a high viscosity medium, in the process of liquid delivery received a flow failure signal, how can we solve this problem?Move the hydraulic end by loosening the 4 pump head screws. Rotating stroke length to 10%, and seize the hydraulic end, and then slide out of the screw hole, then the screws do not touch them, but still control the back and diaphragm. Then rotate the component counter clockwise, with a slight resistance, and the diaphragm will loosen from the electromagnetic axis. If the diaphragm is not loose, use some grease on the contact surfaces of the diaphragm and the electromagnetic shaft. After a few minutes, gently tap the diaphragm with a small plastic hammer. Then proceed again in accordance with the above description.
Q:What's the word "pump"? Is that what advocates mean?RT
What is a "fan"?In recent years, the term "fan" often appears on the newspaper Web page, whether it is a team, a singer, a sports car and a toilet, all of which have their own fans
Q:Piston filling and peristaltic pump filling which precision is high?
If the unit area is large, the accuracy of the plunger is certainly not high. The peristaltic pump is used by means of extrusion roller extrusion pump to promote the solution, this also depends on the unit cross section size, the same motor accuracy is very important.
Q:What happens when a centrifugal pump is selected?
The air pump.The pump itself is mechanical failure.The pump outlet valve core off.Low voltage power.
Q:What is the working pressure of the hydraulic pump in the hydraulic transmission system?
The choice of pressure depends on the size of the load and the type of equipment. Consideration shall also be given to the assembly space, the economic conditions and the availability of components for the actuators.In the case of a certain load, low working pressure, is bound to increase the structure size of the actuator on some devices, the size must be limited, from the perspective of material consumption is not the economy; on the other hand, the pressure to choose too large, the pump, cylinder, valve and other components of the material, sealing and manufacturing accuracy requirements very high, must raise the cost of equipment.
Q:Fire control center manual start fire pump directly, multi line control
The vertical line NHKVV-7*1.5 is the remote starting line of fire controller to fire pump room.
Q:What's the difference between non negative pressure and variable frequency water pump?
When peak water is used, the fluctuation of water pressure will be the same for customers! Because the key to the fluctuation of hydraulic pressure is the flow rate of the pump and the lift of the pump. As long as the flow of the selected pump is large enough, the tank is large enough, the lift head is suitable, and the pressure fluctuation is relatively small. And the selection of non negative pressure and frequency conversion pump group is not directly related. If the municipal tap water pressure and water sufficient (large enough diameter), the use of non negative pressure is better. If the municipal tap water pressure and water shortage, you can only use the frequency converter pump + water tank, no negative pressure can not be used.
