FAQ

What should be used to pay attention to the use of mechanical pumps?
Overall: large pump should first do a good job of the foundation, to find a good whole, fixed, and motor, pump should be added good oil, the first test of the motor, and then conjoined tests
What are the constant pressure pumps?
Chlorine booster pumpThe pressure range of chlorine booster pump is large, and different pump can be used to obtain different pressure area. The input air pressure is adjusted and the output pressure is adjusted accordingly. High pressure can be reached, gas 90Mpa. Wide range of flow, for all types of pumps only 0.1Kg pressure can work smoothly, at this time to obtain the minimum flow, adjust the intake volume can be obtained after a different flow. Easy to control, from simple manual control to fully automatic control, can meet the requirements. Automatic restart, regardless of what causes the pressure drop in the pressure loop, will automatically restart to supplement leakage pressure and maintain constant loop pressure. Safe operation, gas driven, no arc and spark can be used in dangerous situations.s
What are the parts of a pump? How do you classify it?I just want to know
Before opening the pump suction pipes and pumps must be filled with water. Open the pump, the impeller rotating speed, which leaves the liquid together with the rotation under the action of centrifugal force, the left outside impeller injection, injection of the liquid in the pump shell gradually slow the spread of indoor speed, the pressure gradually increased, and then from the pump outlet. The outflow discharge tube. At this time, in the leaves at the center of the vacuum area of low pressure liquid was thrown to the surrounding formation there is no air and no liquid, liquid pool at the surface of the liquid under the action of atmospheric pressure, through the suction pipe into the pump, the liquid is continuously pumped up from the liquid pool is also continuous outflow from the discharge pipe.Mainly by the impeller, pump shell, pump shaft, bearings and packing sealing devices and other componentss
How accurate is the metering pump?
The measuring accuracy of the stable metering pump is as follows:In a diaphragm metering pump, the reciprocating motion of the plunger is passed to the diaphragm through the hydraulic chamber between the plunger and the diaphragm. In order to maintain the normal movement of the diaphragm, the hydraulic chamber is required to keep the volume of the liquid in the space (usually using hydraulic oil) unchanged. In order to ensure that the volume of the formation of membrane movement is always equal to the stroke volume of the plunger pump, so as to maintain the stability of the flow, but in the actual operation of the pump, the plunger seal will inevitably cause leakage at the same time, there may be a gas into the hydraulic chambers
Fire hydrant pump button, under what circumstances do not need to install?
The installation of hydrant pump buttons depends on the type of water supply:(1) municipal water supply; (in this case, do not have to install)(2) there is a fire pump; (must be installed)s
What are the internal losses in centrifugal pumps? How did they come about?
Volume loss: loss due to leakage;3. mechanical losss
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.s
Pump operator's responsibility Sharing the rules, responsibilities, etc..
1., consciously abide by the traffic control department management rules, to achieve civilized driving, safe driving.2. responsible for the daily maintenance, cleaning and cleaning of the pump truck, and ensure the equipment is in good condition.s
