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 adjust the flow of piston pump?
The oil pan with oil liquid through the suction port and the piston cylinder; from 180 degrees to 360 degrees, the piston cylinder volume decreases, so the oil liquid in the pan with oil discharged from the outlet of the liquid. The pump works continuously as long as the drive shaft rotates.
Q:Working principle and diagram of axial piston pump with pressure compensation variable
Adjust the flow characteristics, the first limit screw to the top, according to the flow and pressure changes in the required range, adjusting the spring set, the initial flow pressure began to change to meet the requirements, then the limit screw to the ultimate pressure when the flow is no longer changed, the relationship between flow and pressure the changes are determined by the pump itself.
Q:What should I pay attention to when buying a pump?
There are hundreds of water pump manufacturers in China, some of the family owned private enterprises are assembled in some areas, and the quality of the products is very good and bad, which makes it difficult to choose and buy. The main points are as follows:First, according to the required flow, lift, shaft power, efficiency, the necessary cavitation margin (or suction) and the use of conditions, the initial determination of the pump type, name, select the rated value and the required parameters of the same pump.
Q:Advantages and disadvantages of canned pumps
The graphite bearing lubrication medium, make the operation less noise and manual, reduce maintenance costs; in recent years, bearing material added with silicon carbide SIC, super hard, life is better than that of graphite bearing.The vertical structure can be installed on the pipeline like a valve, the installation is convenient and quick, and the motor and the impeller can be drawn out only when the utility model is used, and the pipeline is not needed to be removed.The utility model can be installed and run with a shock absorber or a damping pad, so that the pump is less noisy at running time.
Q:Water pump does not produce water, what are the reasons?
The reason why centrifugal pump does not produce water:1. pump inlet or sink, water tank water shortage.2. water pump pipe blocked or valve not open.
Q:What should be used to pay attention to the use of mechanical pumps?
Overall: large pump should first do a good job of the foundation, to find a good whole, fixed, and motor, pump should be added good oil, the first test of the motor, and then conjoined test
Q:What is the lift of diaphragm pump?
Hello, pneumatic diaphragm pump head is liquid, the energy obtained through the pump is called the head, it is related to the flow rate and pump speed, liquid density.Please adopt.
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:Why can't the centrifugal pump pump the vacuum?
Running process: depending on the centrifugal pressure of the liquid in the impeller, the liquid is sucked into the liquid, and the liquid in the pump shell has the conversion of the energy form, so that the fluid can obtain the mechanical energy mainly with the static pressure.The characteristics of the system: the suction diameter than out of large diameter, the general valve installed.
