Q:What should I pay attention to when buying a pump?
Four, packing inspection1. with the pump supply documents shall include: product certification, specification, packing list, agricultural pumps (such as submersible pumps, centrifugal pumps, mixed flow pumps, self-priming pump etc.) should be "Three Guarantees certificate", the implementation of the production permit (such as pump submersible pump, high pressure pump, high temperature pump 5 pump) we should have a production license.2. plugging of the orifice, to withstand wind and rain invasion, and should be strong, can withstand accidental damage.3. pumps and all supplied bulk parts supplied with the pump shall have the required identification number and shall be clear.4. pairs of oil lubricated bearings, bearings tank oil should be discharged, and fixed with "need oil filling" warning signs.
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:Significance of water pump model ISO50-160
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. Pump performance parameters include flow, suction, lift, shaft power, water power, efficiency and so on;
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 is the pumping property of concrete?
Pumping capacity means that fresh concrete can be transported by concrete pump, and concrete construction can be carried out with high efficiency. 'pumping' is a qualitative statement
Q:How many kinds of pumps are available and the operating principles of various pumps?
There are many kinds. See what divides.According to the working principle can be divided into: the power type pump, also called pump or impeller vane pump, depending on the dynamic effect of the rotation of the impeller on the liquid, the continuous energy transfer to the liquid, the liquid kinetic energy (mainly) and the pressure will increase, then converting kinetic energy into pressure energy through the discharge chamber, and can be divided into centrifugal pump, axial flow pump, partial flow pump and vortex pump etc..
Q:What's the meaning of the pump head in the water pump, please advise, thank you
The pump head of the centrifugal pump refers to the shell that contains the impeller and impeller, and also includes the shaft part that drives the impeller. It can be used as the part of the motor and shaft coupling and the base.
Q:What are the starting and stopping procedures for centrifugal pumps?
Operation method and operation procedure of self-priming centrifugal pumpClick number: 440 release time: 2011-7-24Centrifugal pump method, centrifugal pump operation steps, centrifugal pump use steps
Q:What is pump suction work?
Pump is mainly used to transport liquid, including water, oil, acid and alkali liquid, emulsion, suspension emulsion and liquid metal, etc., also can transport liquid, gas mixture and liquid containing suspended solids.
Q:What are the uses and precautions of magnetic pumps?
5, after the motor starts, slowly open the drain valve, until the pump into the normal working state, and then discharge valve to the desired opening;6, before the pump stops working, should first close the exhaust valve, and then turn off the suction valve.
