Q: How to adjust the flow of piston pump?: Changing the size of the current in the solenoid valve can change the angle of the tilting element, and then change the stroke length of the plunger in the pump cylinder, that is to say, to change the flow of the pump. An inclined angle is called a quantitative pump, and the angle of inclination can be changed, which is called a variable pump.

Q: A residential building with a floor height of 11 stories and a roof height of 33 meters. The height of the water tank is 37.7 meters. The basement is -3.3 meters, only set fire hydrant, fire pump only consider the indoor fire water, fire flow should be 10l/s. Now select a fire pump, concrete should be much traffic, big head, flow determine how? How to determine the head, I hope to say some more detailed, thank you, and there is to explain this question, why is the fire pump lift 120?. Thank you: 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 are the causes of pump shock?: 6., water pump relatively serious cavitation, improve the water level of the water tank, reduce water output7., impeller and motor rotor imbalance, overhaul8. pump shaft bending or abrasion overhaul

Q: What are the characteristics of a pipe shield pump?: Four, high melting point in the pump hydraulic side and the motor side with a jacket, the jacket can be steam or a certain temperature of liquid to prevent high melting liquid crystallization. The outer circulation pipe of the pump should also be insulated (heating) jacket. Five, high pressure shielding pump shell is a high pressure container, so that the pump can withstand high system pressure. In order to support the shield under internal high pressure, the stator coil itself can be used to bear the pressure. Can also be made in high temperature and high pressure under the operation of the canned pump. Six, since the suction port of the pump impeller center is much higher than that in stopping the pump, when inhaled NO liquid in the tube, the impeller and the increase of the pump chamber is filled with liquid, and then start without irrigation, the pump can work. Self-priming pumps are especially suited for extracting liquids from underground containers. In addition, according to different methods can be divided into liquid type, mud type, high pressure pipeline type, as well as for ships, nuclear power plants and absorption refrigeration devices for various types of canned pumps. Can also be divided into vertical, horizontal, online and single-stage, multi-level and other different types.

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: Types and differences of pumps: (I) volumetric typeClassification reciprocating rotary typeThe basic principle of reciprocating action by the piston in the cylinder in the cylinder volume changes again, with the suction and discharge of fluid in the shell or the rotor rotating member rotates, the volume of work between rotor and casing changes to the suction and discharge fluid, such as piston pump gear pump, screw pump(two) blade type;The main structure of vane pumps and fans is rotary, bladed impellers and stationary housings that rotate fluid through the impeller to do work, thereby enabling fluids to obtain energy

Q: Do you have a suction pump higher than 9 meters?: This screw self-priming pump suction process can be more than ten meters or more, my family is using this

Q: What flowmeter is installed after the pneumatic diaphragm pump?: Compressed air source, the general pneumatic diaphragm pump starting gas source for 0.1~0.2mpa,The maximum working pressure is 0.7~0.8mpa, so in this pressure range, you can use the air filter relief pressure valve gas pipe, adjusting for air pressure, when the pressure is bigger, diaphragm movement faster, so the greater the flow, and vice versa

Q: How to maintain and repair the booster pump of pipeline pump?: I. installationAssembly and disassembly1. scrub all the spare parts to be cleaned.2. mechanical seals are installed on the main shaft of the motor, and a small amount of clean turbine oil or 20 oil is added to the surface of the mechanical seal.

Q: What is the difference between centrifugal pump and self suction pump? Which is better?: In order to prevent the filling liquid into the pump shell because of gravity flow in the low groove, in the pump suction pipe at the entrance of a non-return valve (valve); if the location of the pump below the liquid level in the tank, then start without irrigation pump.Self-priming pump is a self-priming centrifugal pump, centrifugal pump is a kind of.Specific choice of a pump, depending on your specific parameters and conditions of use.
