Type DG: The pumps are suitable for pumping clean water without solid particles or other liquids whose physicochemical property is similar to that of clean water with the temperature range from -20℃~150℃.
Capacity : Q:6~540m2/h
Head : H:33~1056m
Construction: The pump is horizontally installed. The inlet and outlet are under the split surface and in the perpendicular direction with pump central shaft-line, during the course during the course of installation, you needn't to remove the motor and the pipes.
Type SLA is vertically installed the inlet and outlet at a same center line and the case and cover are in the perpendicular direction.
Bearing: Both end of the pump are rolling bearings (type 24SA_18, 16SA_90 could use the sleeve bearings)to support the rotor, the lubrication oil is dilute oil or grease.
Materials of tolerance: The material s of tolerance is cast iron or it can be changed into cast steel and bronze, but it should be signed in the order.
- Q: Know flow and lift how to calculate the pump power?
- The pump power (kw) ={9.61* flow (cubic meters per second) * head (m)}/.Where ETA is device efficiency, including mechanical, electrical loss and other factors, generally between 55%~80%. The smaller the pump, the lower the efficiency.
- 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: The suction pump has a nominal suction range of 30 metersHow deep can a well be sucked?Well, sixteen meters,
- Vacuum pump plus form must not reach a standard atmospheric pressure vacuum, so the general can absorb 8 meters is very good, and the self suction pump itself and loss, the horizontal self-priming pump can suck on basic 4~6 meters is very good, self-priming pump. Suction lift of 30 meters is purely in the Mongolian people, does not comply with the laws of nature, obvious anti science.
- 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: Pump unloading in hydraulic transmission,
- Unloading is pumping oil directly back to the tank, the pressure is very low, energy saving
- Q: Fire control center manually start the fire pump directly, multi line control, called straight up line NHKVV-7*1.5, my understanding is: straight line from fire control center
- 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?
- Re pressure to a given pressure pressure zone water supply, than frequency conversion water pump energy savingFrom a health perspective, a water tank variable frequency water pump, water tank and the atmosphere, easy occurrence of water pollution two, no negative pressure equipment without negative pressure tank and pump and valve fittings etc., no water tank, the whole process of water supply of water is completed in a closed system, with air contact to avoid two pollution problems water supply.From the management point of view, no negative pressure is fully automatic intelligent operation, reduce management costs, no water tank, reducing the trouble of tank cleaning. No negative pressure is the upgrading of variable frequency water pump products
- 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: What are the main performance parameters of the pump?
- The main performance parameters of the pump are:The energy obtained by pumping a unit weight of liquid through a pump. In H, the unit is m.
- Q: What is the difference between an air pump and a water pump?
- A pump is a machine that transports liquids or pumps liquids. It will be the prime mover of the mechanical energy or other external energy transfer to the liquid, the liquid energy increase, mainly used to transport liquids including water, oil, alkali liquid, emulsion, suspension emulsion and liquid metal, but also transport liquid, gas mixtures and liquids containing suspended solids.
