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:Pump suction and pressure side road why should vacuum table and pressure gauge, and what role they have?
The water pressure (vacuum) is measured by the vacuum meter. The pressure gauge is used to measure the pressure at the water end, and the difference between the two is the lift of the pump
Q:I have a mechanical well how to choose the size of the pump
First, determine the size of the electrical well and then the depth. Is it water injection or pumping?The pressure of water injection pump is much higher. If you pump water, it depends on how much water you need every hour Plus you enter the water depth of +10 meters, you can basically a good selection.
Q:Water pump part is stainless steel, which part is it?
The part of the pump head, that is, the part of the flow
Q:What does the temperature range of the pump mean?
Not be too cold or hot water, will be frozen.
Q:When the pump is connected in parallel, will the head and flow change?
Depends on how you do it.If you have a pump, the original network is the same, you add a pump, the result is the head and flow increases, the efficiency also changed, increase the number of head and flow, depending on the network characteristics, network characteristics such as steep increase, economy is also poor, which is not recommended. In fact, the actual flow of two pumps plus the actual lift equal, the problem is that the head, flow point of operation has changed.If it is new design, according to the required flow calculation of the required head, according to the head, half of the flow to select the pump, that is, two pumps flow volume, lift equal.
Q:The diving pump in the aquarium stops and stops on the goldfish
Generally do not close the filter at night, at 56 in the morning when the most likely hypoxia. The sick fish are all fished out. Fast infection
Q:How does a pump pump water?
Centrifugal pump is centrifugal force, and household deep well pump is primary pressure
Q:How many lift pumps should be used for 100 meters tall buildings?
35m lift around. HVAC pump lift is generally between 5~50m, the selection of the head is mainly to see the difference between water pressure. As head of 35m as an example, if the inlet height of 60m, so the theory of height =60+35=95m, if all pipe closed air conditioning water system, and resistance of the equipment for water is equal to the pressure difference is equal to the pump head to choose your height, and out of the water is the same, the resistance loss of lift all into the water. The calculated resistance loss is needed to pump lift. The resistance component (1) chiller resistance at 60-100kpa (2) water collector resistance in 120-200kpa (3) 20-50kpa (4) air terminal equipment body resistance is generally not less than 40kpa so 100m building the resistance calculation of estimated value = (1) 80kp+ (2) chiller resistance pipe, the collector resistance (140kpa+ 3) air terminal equipment 40kpa+ (4) body resistance 50kp=310kpa safety factor of 10% 320x1.1=341kpa H= P/ (head of pressure water density * acceleration of gravity g =352000/ (10m) X9.8 =34.8m fand) so we head for 35 meters
Q:How to change the frequency of a water pump with a pump?
I have encountered this problem, 1, check the reverse pump outlet single flow valve is damaged2. Check whether the three wires of the motor are in wrong position and reverse when starting
