Q:What are the ways of hydraulic pumps?
There are several ways:Direct flow mode, such as external gear pump;Port plate, such as vane pump, axial piston pump, etc.;
Q:Double floor sewage pump circuit diagram of a small problem
Question 3 when the water level is low, when the 1KA is connected, the pump will run depending on where your SS selector switch is located. Its left and right position, running pump and standby pump definition is different, left position is 1#, running 2# standby, right position is 2# running, 1# standby. Only inIn case the high level switch 2KA is connected, the standby pump may work at the same time.
Q:Direct connection pump What is straight pump and non direct pump? What's the difference in structure?
Direct connected pump: pump impeller installed directly on the motor shaft, it looks like a whole, relatively compact, simple installation, but the general power is relatively small (big bad processing connection, but not absolute);Non direct pump: pumps and motors are independent of each other, through the coupling torque transmission, the structure is relatively large, complex installation, to adjust the level / concentricity and so on, the general power is relatively large
Q:What are the constant pressure pumps?
Constant pressure pump is also called the booster pump, the name is used for booster pump, its main purpose is water heater booster, with tall low pressure, sauna, bath and other pressure in the apartment, the lack of water pressure, solar automatic pressurization and so on.
Q:Does the reservoir water heater press the booster pump (high marks)?
60 liters of water storage should be able to drive two bathrooms at the same time bath! Water storage water heater generally does not need booster pump, as long as there is a little pressure, the water heater is filled with water, as long as the tap water can do. You can turn off the hot water valve and see only the amount of water in the cold water. If hot water is much smaller than cold water, it is the reason for the heater. Can you check the water mixer is normal, the one-way valve is installed in reverse.
Q:How many pumps does the 80cm tank use?
Mainly look at the flow of the pump, all pumps have flow signs, such as 15L/HThe above is I at random, meaning that 15 litres per hour. You should calculate the volume of your cylinder, that is, the length of the tank, the width and the height of the water surface, the unit is cm. The result is 1000, which is the volume of your fish tank
Q:Why can the centrifugal pump hold down the pressure?
The pump before starting to pump shell and the water pipe filled with water, and then start the motor, the pump shaft to drive the impeller and water do high-speed rotation, centrifugal water movement, was thrown to the outer edge of the impeller, the pressure water pipeline flow through the volute pump into the pump shell.
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:Any center of the pump
For the first time, the pump and motor were placed on the base and not fastened (Cu Zhaozheng);Second times, the pump and motor have been tightened, the inlet and outlet flange bolts are not fastened;Third times, the pump runs 24 hours later.
Q:What are the differences between the sewage pump and the clean water pump?
The main difference between the sewage pump and the clean water pump is that:Impeller and runner design, as well as other parts of the configuration are very different.1., in order to prevent clogging of sewage pump, the main design of large flow channel, so naturally lead to relatively low efficiency, so the head is generally not high. Clear water pump flow smaller, smaller clearance, the head is relatively high.
