Q: Know flow and lift how to calculate the pump power?
P: the density of refrigerant, when the working fluid is water, P =1ETA - pump efficiency, can not find desirable value =0.8N=30x (200/3600) x9.81x1/0.8=20.44 = 20 (kW)(that is, 20kW motors)
Q: What is a water pump coupling device?
The automatic coupling device of the water pump coupling device has compact structure and small occupation area. The sump pump works because it is submergedThe utility model can be directly installed in a sewage pool, and no special pump house is needed to install a pump and a machine, thereby saving large amounts of land and infrastructure expenses
Q: What are the uses and precautions of magnetic pumps?
5, after the motor starts, slowly open the drain valve, until the pump into the normal working state, and then discharge valve to the desired opening;6, before the pump stops working, should first close the exhaust valve, and then turn off the suction valve.
Q: The water tank of the fish tank does not air out and only has the water outlet
The water pump is cut off, the intake pipe is drawn out, and the water in the air pipe is blown out, then the water pump is put on the surface of the water, and the air inlet pipe is inserted on the surface of the water pipe, and then the water pump is put back into the water, and the water pump is electrified. Try again several times at a time. It should be effective.
Q: What are the reasons for sealing damage of centrifugal pumps?
Three, water shortages caused by running dry grinding damage.This phenomenon is more common in mounted form inlet pressure, inlet air, air cavity pump, pump boot, high temperature operation of the mechanical seal friction at high speed, can not be cooled, check the mechanical seal, the spring tension is normal, the friction surface of charred black, rubber hard cracking.Treatment methods: exhaust the pipe and pump cavity air, replace the machine seal.Four, install too tight, observe the mechanical seal of dynamic and static ring plane, if there is serious burning phenomenon, flat black and deep traces, sealing rubber hardens, lose elasticity.This phenomenon is due to tight installation.Treatment methods: adjust the installation height, impeller installed, with a screwdriver to move the spring, the spring has a strong tension, release after the reset, there is 2-4mm moving distance can.
Q: What does electromechanical vector pump mean?
Commercial buildings: hotels, office buildings, department stores, large saunas, etc.Irrigation: such as parks, playgrounds, orchards, farms, etc.Manufacturing: such as manufacturing, washing equipment, food industry, factories and so on
Q: How can I buy a pump?
Selection principle of pump:1, so that the selected pump type and performance parameters meet the unit flow, lift, pressure, temperature and other requirements, the most important thing is to determine the voltage, the maximum lift, and when the head high reached much traffic.
Q: How many square cables does the submersible pump for 7.5KW need?
According to current I=13A, it is estimated that the cable is less than 10 square meters, so the cable cross section can be calculated at the ampacity of 5A per square meter. The square section of the cable is =13/5=2.6 square. According to the specifications series, optional 2.5 square aluminum cables. When the cable is longer, it is safer to choose 4 square aluminum cables.
Q: Why can't the centrifugal pump pump the vacuum?
Characteristic equation of centrifugal pumpStudy the effect of fluid on centrifugal pump to obtain energy.The experimental condition of u is that the ideal fluid of unit weight bends the flow between blades at infinity.U investigated the mechanical energy balance of the fluid between the adjacent two inlet and outlet sections, that is, the relationship between theoretical pressure head and theoretical flow.
Q: How accurate is the metering pump?
The measuring accuracy of the stable metering pump is as follows:In a diaphragm metering pump, the reciprocating motion of the plunger is passed to the diaphragm through the hydraulic chamber between the plunger and the diaphragm. In order to maintain the normal movement of the diaphragm, the hydraulic chamber is required to keep the volume of the liquid in the space (usually using hydraulic oil) unchanged. In order to ensure that the volume of the formation of membrane movement is always equal to the stroke volume of the plunger pump, so as to maintain the stability of the flow, but in the actual operation of the pump, the plunger seal will inevitably cause leakage at the same time, there may be a gas into the hydraulic chamber
