Q:Operating procedures for measuring pumps
Pressurization(1) for the discharge pressure below 2.0MPa, then the pump stroke length should gradually increase, each increase of 20%, to maintain 15 minutes.(2) for the discharge pressure greater than 2.0MPa, you need a special pressure, to ensure that the pump discharge pressure gradually increased, each time for the final row pressure of 20%.(3) when the pressure is not increased, the stroke of the pump is gradually increased by 20% strokes per time.Note (1) when pressure is applied, the pressure gauge should be observed at the side of the loading side (slow motion)(2) check ammeter, forbid overload
Q:What is a vacuum pump for?
You are not confused by different names. It is mainly used in folding machines, paper cutting machines and water treatment aeration
Q:Significance of water pump model ISO50-160
According to different working principles can be divided into volumetric pumps, vane pumps and other types. Displacement pump is to use its studio volume changes to transfer energy; vane pump is to use the rotating blade and water interaction to transfer energy, there are centrifugal pumps, axial flow pumps and mixed flow pumps and other types.
Q:Working principle and diagram of axial piston pump with pressure compensation variable
The size of the outlet flow pressure compensated variable displacement pump with outlet pressure of approximately in a certain range according to the constant power curve. When the pressure oil from the main part of the channel (a), (b), (c) into the inferior vena cava (d) variable shell, oil by the channel (E) respectively into the channel (f) and (H), when the spring force is greater than the oil (f) into the lower end of the piston ring servo hydraulic thrust area when the oil liquid (H) to the chamber (g), push the variable downward movement of the piston, the pump flow increases. As for the hydraulic servo piston end thrust force ring shaped area is greater than the spring when the servo piston moves upward, blocking channels (H), the (g) (I) through the cavity of the oil cavity pressure relief, at this time, the piston moves up, the variable head angle decreases, the pump flow rate decreases.
Q:Does the control cabinet of the fire control pump need to be related to the fire control room?
Automatic sprinkler, which is mostly used in this device or high water tank, the whole set of equipment must meet the most unfavorable point (the farthest the highest point of water) water pressure of the faucet.
Q:How to select the fire pump?
According to the water quantity form fire flow water supply system fire safety in high-rise building fire hydrant pump lift is 10L/s, accurate algorithm is to say after a simple calculation with each indoor hydrant flow is two 5L/s bolt so to get the most unfavorable point for the calculation unit to calculate the minimum requirements, with the most unfavorable point suppository pressure specifications 0.07MPa, partial loss of the most unfavorable line and the line (according to the equivalent length) and loss (according to the material resistance coefficient), and finally the pump head loss of gravity difference. But we just calculate the construction elevation difference multiplied by 110% to 120% to determine the head {there is a need to know is: conversion head (m), (kg) and MPa kg 1MPa=10 kg = 100m is the vertical water column on unit area pressure conversion
Q:What do you mean by the self coupling device on the pump?
Installation of GAK self coupling device:The installation of automatic coupling submersible sewage pump is mainly the installation of coupling device and the lifting of pump. In the pump before the installation of the rings on the chain, and the pump used for lifting.Installation procedure of coupling device:The coupling frame with four bolts fixed on the pump body; the water outlet pipe is fixed on the substrate; positioning cone mounted on the pipe seat; the lower end of the guide pipe is sleeved in the positioning cone, the upper end is sheathed on the guide rod of the rubber block; the guide rod frame is fixed on the pool wall. The function of the rubber block: the axial compression degree of the rubber block is adjusted by the screw on the guide rod frame, so that the diameter of the rubber block is consistent with the inner diameter of the guide rod, and the guide rod is stable.
Q:Household automatic booster pump, how much pressure can you work automatically?
With the pressure does not matter, because the pressure is small, it is necessary to boost the pump, the water pressure with the pipe flow and the size of the booster pump related
Q:Fire control center manual start fire pump directly, multi line control
Multi line linkage NHBVR-4*1.5 is a positive pressure blower and smoke exhaust machine fire fighting equipment
Q:What's the submersible pump?What is a submersible pump, and what about it?
Not afraid of water, because it is placed in the water itself to cool themselves, you can use for a long time. The amount of water pumped and the height of the water now basically meets the needs of a small amount of individual and a large number of factories. This is the submersible pump, the water pump in the water. You can see.
