- Q: Fire pump and shower pump flow head selection, high resolution.
- Selection of flow head of fire pump and spray pump:1, the volume is greater than 5000 is less than 10000, the minimum water consumption of indoor fire hydrant is 10L/s
- 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 are the starting and stopping procedures for centrifugal pumps?
- The use of centrifugal pump can be divided into three steps, namely, start, run, stop.Start: you should do the following preparation before starting:(1) check the water pump equipment in good condition.(2) the bearings are filled with oil, the oil level is normal, and the oil quality is qualified(3) all the inlet valves of the centrifugal pump are opened.(4) pump water injection or vacuum pump diversion (except for flow), open the vent valve exhaust.(5) check the leakage of shaft seal. It is advisable to fill the seal with a little drop of water.(6) the motor rotates in the right direction.
- Q: Why can't the inlet of centrifugal pump be negative pressure?
- Therefore, the centrifugal pump inlet pressure can be negative, and negative number, should be used to pump cavitation margin and liquid saturated steam pressure parameters to specific calculation. Sometimes, the liquid saturated steam conveying pressure is very high, such as the 9 m water column, then the minimum pressure of the pump inlet should be equal to 4+9=13 meters, the atmospheric pressure is higher than 3 meters, not only for negative pressure, even higher than the atmospheric pressure to work properly.
- Q: What is the working pressure of the hydraulic pump in the hydraulic transmission system?
- The operating pressure of the hydraulic system depends mainly on the load. Generally speaking, the working pressure of the hydraulic system means the highest working pressure of the system. If the pressure is higher than the value of the equipment, the relief valve works to relieve pressure. The actual working pressure of the hydraulic system is determined by the load, which refers to the actual pressure of the hydraulic oil and can be read directly from the pressure gauge. The pressure increases with the increase of the load. You Li's balance can know: the thrust of the cylinder = the load, the thrust of the cylinder = the working pressure of the hydraulic oil, the working area of the cylinder, the working pressure = the load / the area of the cylinder.
- Q: Bolus dosage of infusion pumpWhat is the purpose of the pill dose control in the special safety standard for infusion pumps? If the risk is not properly controlled, what is the degree of risk? And how can the open infusion pump be used in this regard?
- (three) infusion limited number of pills produced after the dose of obstruction by infusion pump and specification of the matching test, will reach acceptable when the storage pressure of the pressure to determine the alarm blocking. Thus, some have restrictions on the infusion tube blocked after the maximum dose pill may have blocked the trigger before the alarm.
- Q: Harm of air pump and pump
- Minimum starting current when centrifugal pump of such a small impact on the grid but long closed operation will make the liquid in the pump to the pump overheating temperature is too high will lead to the problem of the seal to a certain temperature will cause deterioration of oil bearing bearing caused by excessive wear and even bite dead
- Q: Why is the flow of the pump too small will occur cavitation phenomenon?
- This is because the impeller of the centrifugal pump rotating speed under the drive of the prime mover, when the valve opening decreases, flow rate is too low, can not be taken away by the friction heat generated by the impeller and the liquid completely, make the temperature of the liquid inside the pump. Thus causing liquid vaporization, forming cavitation. Especially in the power plant, the boiler feed pump is more remarkable. Therefore, when throttling regulation, we should set up recirculation system, increase the output flow of the pump to prevent cavitation. When the feed water rate is reduced to 1/3 of the maximum flow rate, the recirculating gate shall be opened so that the flow of the feed pump will be increased properly to ensure that the liquid temperature in the feed pump does not rise.
- Q: Does the control cabinet of the fire control pump need to be related to the fire control room?
- Normal words are needed, but when you check and check, has anyone checked?
- Q: Metering pumps related matters
- 1., exports higher than imports, avoid siphonage2. the pump head and the injection valve require vertical installation3., the attached pipe can be tightened by hand, please do not use the tool; the thread does not use the raw meal belt4. the supply voltage is stable and grounded5. installation environment clean, spacious, well ventilated) 1) metering pump suction is not normal
