Q:The reason why the pump is overloaded
(1) the influence of the basic installation on the equipment.The quality of equipment foundation installation has great influence on the quality of equipment operation. Iron pad placed properly, causing around the foot bolt hanging device, in alignment and fastening process for iron pad hanging, tighten anchor bolts will cause deformation of crosshead slide in the crankcase, the cross head is blocked in the operation of reciprocating load increases when the chute.W5 type reciprocating vacuum pump in the structural design of the cylinder body is cylinder, and the piston, intake and exhaust valve after the heavy weight in the foundation design without considering the cylinder support or hanger, the cylinder will be in a suspended state, because the weight of the crankcase cylinder will cause deformation of the cylinder and slide and slide the concentric degree of difference, so that the cross head is blocked in the slideway and the piston reciprocating operation is blocked during the reciprocating motion in the cylinder caused by the increase of the load.According to the above analysis, inspection found that the vacuum pump end of the cylinder body is slightly lower than the end of the crankcase, cylinder pad iron is low, deformation of crosshead guide foot bolts, the cross head caused by load increases in the slideway and the piston in the cylinder reciprocating operation is blocked, this is one of the reasons causing motor overheating.(2) cylinder and valve coking;The influence of process, cylinder and valve of reciprocating pump is easy to coke, Coke will cause the piston cylinder and piston in reciprocating cylinder operation when the load increases the valve is blocked; coking will cause poor exhaust, the valve closed lax, increasing load, low vacuum degree; clearance at the cylinder piston striking the cylinder will cause coke it will increase the load of cylinder, valve has found the phenomenon of coking, which is mainly caused by the low degree of vacuum.
Q:What are the categories of pumps?
As long as you see, you need flow, lift, power
Q:Submersible pump reverse impact on the pump
Water pump is easy to burn out.Submersible pump is an important equipment for deep well water extraction. When in use, the whole unit dives into the water. The extraction of groundwater to the surface is water, mine rescue, industrial cooling, irrigation, water lifting, ship ballast, also can be used in fountain landscape, hot water submersible pump for hot spring bath, but also can be applied to the extraction of groundwater from wells, can also be used in rivers, reservoirs, canals and other water projects. Mainly used for irrigation and high mountain areas, drinking water, but also for the central air conditioning cooling, heat pump, cooling pump unit, city, factories, mines, railways, construction site drainage use. The general flow can be achieved (5m per hour, fand fand ~650m) head can reach 10-550 meters.There are several kinds of electric submersible pump, in line package is oil immersed and water invasion there is dry must first read the instructions before use, cannot be wrong, not long before use, must have to make the impeller turn, or because of long time card dead burning.Before the pump is opened, the suction pipe and pump must be filled with liquid. 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 continuously from the outflow discharge tube.
Q:How to remotely control submersible pumps?
This is relatively easy to implement, to a remote control within the specified scope control, and use mobile phone SMS or ringing control, you make a phone call or Clockwork SMS can control the submersible pump switch, the switch is not used since a ran. This remote control switch products, in the Alibaba, my family has used, it is convenient, not expensive, more than 100.
Q:Is there a water pump with its own flow regulating function?
It has a water pump with adjustable flow capacity, I used it. Can also landing professional production pump manufacturers web site inquiries.
Q:What is the function of the backflow pipe of the fire pump?
Generally, it is used to test the fire pump. The procedure is to start the fire pump - turn on the return pipe - return the water to the pool. The purpose of the installation is to prevent damage to the pipe caused by the excessive pressure caused by the pump.
Q:Why does the pump head decrease when the pump flow rate increases?
First of all, the power of the pump is determined by the motor. When the power is certain, work must be done. According to w=mgh, the flow determines mg, the head is h, you think, if the flow rate is large, is the head smaller?. This is theoretical, and at the same time, you see, the water pump characteristic curve can also see that the flow rate increases, the corresponding smaller head.
Q:What is the difference between a low pressure pump and a high pressure pump?
The specific speed of the high pressure pump is relatively smaller than the speed.Lift is not the same, the same flow, high pressure pump head high.Pump and shaft materials are not the same, high pressure pump raw material demand is higher, to be able to accept greater pressure and torque.The size is different, the pump body of high pressure pump is larger.Bearings can also be different, low pressure pumps are rolling bearings, and high pressure pump power, then some pumps are selected sliding bearings.The support method can also be different, the low-pressure pump is the pump foot support, but the high pressure pump can be the intermediate support.
Q:What's a small soft pipe for a submersible pump in a fish bowl? How do you use it?
The little air hose is had to pump in pump operation, to play the role of oxygen, generally want to let the oxygen hose head above the water, or to go into the air, and lose the function of oxygen, if the tank is large enough, every day to open the filter pump. Use hose plus oxygen does not matter.
Q:Domestic pump does not turn, but the motor is energized what is the problem?
This is the start capacitor is damaged, or start the coil break, it is recommended to check if the coil wire in the end can be connected, if left in the tank to replace the coil, if the capacitor is a replacement can (470V, 10uF).
