Q:How many concrete pump tube diameter

High pressure is the outer diameter is Phi 140 Type 150 type low pressure pipeline; pipe diameter is Phi 159 pipeline, high pressure pipeline diameter is phi 168.

Q:I live on the 8 floor. Often there is no water. Life is very inconvenient. What kind of pump do I have to install? What should I pay attention to when I buy it? What's the pump for that brand? Should it be installed in that position?

Installation method of hydraulic pump(1) according to the technological requirements and the cavitation conditions of the pump, the installation height check and the civil engineering of the foundation are carried out.(2) prepare a series of flat washers and wedge gaskets of different thickness before installation.(3) according to the characteristics of the pump conveying medium, determine the material of the gasket at the connection and process the gasket.

Q:Hydraulic pump displacement refers to the pump shaft what?

Displacement of the hydraulic pump refers to the axis of each turn, the volume discharged, called displacement, the unit is ml (ML),

Q:What is cavitation, centrifugal pump cavitation phenomenon how to solve?

In order to make the pump full of liquid, usually in the valve installed at the bottom of the filter screen along the suction pipe, the valve until the end against the valve, strainer prevents the solid material into the normal operation of the pump impeller damage or hinder the pump.

Q:What is the name of the day pump and ground pump? Specific introduction

PumpGround pumps are used very frequently in many large basements, because they have no boom, so they need to be taken over manually. In addition to the site, for those days to pump the high-rise buildings, such as 200 meters or 200 meters altitude, can also take over to transport concrete by pump, but the premise is to have enough power to pump concrete will hit above the height and the length of nozzle can reach the height of the floor.Thus, the day pump and ground pump have their respective advantages. The pump is easy to use, but the ground pump can make up for the height that the pump can not reach. At the same time, the price is relatively cheap, so users can choose the corresponding concrete pump when they are in use.

Q:What are the parts of a pump? How do you classify it?I just want to know

The liquid ring pump: pumping air, the working medium is generally at room temperature water gas lift pump: simple structure of submersible sewage pump: a form of basic principle, performance parameters of centrifugal pump, with it the same. Underwater installation, sound, water cooling condition, screw pump: spiral lower invasion water medium variety formThere are too many kinds of pumps, such as submersible pumps for wells, centrifugal feed pumps, sewage pumps, etc. the submersible pumps are wet, oil immersed, etc.The water pump for automobiles is divided into oil lubrication and grease lubrication,

Q:Common failure treatment of piston pump

x09x09 (3) no connecting key on pump shaft or motor shaft1) break2) missing x091) replace key2) patch keyx09x09 (4) pump internal slide vice stuck1) the clearance is too small2) parts accuracy is poor, assembly quality is poor, gear and shaft coaxial deviation is too large; plunger head clamping; blade perpendicularity difference; rotor pendulum difference is too big, rotor slot has wound or blade has scar, force after fracture and stuck

Q:What are the basic technical parameters of the pump?

Two, pump head H head is the unit weight of the liquid pump pumping from the inlet of the pump (pump inlet flange) to the outlet of the pump (pump outlet flange) energy value. Effective energy is a Newtonian liquid through the pump unit is obtained. The N m/N=m, the height of liquid column pumping liquid. Habits referred to as meters. Three, the pump speed is n RPM pump unit time revolutions, represented by the symbol n, the unit is r/min. four, the pump NPSH NPSH NPSH is also called net positive suction head, said main parameters of cavitation performance. Cavitation has been used a h power of five, the power of the pump. And the efficiency of the pump is usually refers to the input power, which is the prime mover on the pump shaft power, it is also known as the shaft power, denoted by P;

Q:Household automatic booster pump, how much pressure to work automatically, the water pressure and how many kilograms?

Household automatic booster pump is not started by pressure, it is induced water pump, that is boiled water faucet
