Q:Installation position of check valve for water pump
Check valves are generally installed at the pump outlet and exit control valve position. Self suction pump check valve installed in front of the pump, suction port better!Ordinary centrifugal pump check valve flange from the pump outlet flange is generally 300mm-500mm, its purpose is: when the pump is stopped, to prevent backflow of water to the pump body in the pipeline, resulting in the impeller reversal (generally positive rotation is more impeller impeller and shaft tight) that damage the impeller and pump head. Therefore, the height can not be too high, too high, there are too many water reflux, the consequences can be imagined.But there are self suction pumps, self suction pumps, check valves, flanges, pumps from the body, the outlet flange generally 1 meters to 1.5 meters.This is determined by the structure and working conditions of the self-priming pump. Self suction pump start, the pump is a gas at first, the main purpose is to exhaust the rotation of the impeller, will also play out some of the water, this time need to exhaust gas, water will need to return, if the valve is installed in the 300mm-500mm, then a lot of water can not return to the pump body (can also cause check valve is closed), effect of self suction pump work.Self suction pump check valve installed in the suction port of the pump better, this is not upstairs nine, brother said, must be installed in the export, this is wrong. Installed in the inlet of the purpose: it is time to stop the pump, there is generally no reversal of pump impeller, but to prevent the pipeline inside emptying (fluid inside the pipe can be in pipe) is beneficial to the self suction pump for a restart! Therefore, the self-priming pump check valve is best installed in the inlet pipe of the suction port.
Q:Pump pumping small is what happened?
You are lifting pump or submersible pump ah? Lift pump before pumping water pump, first open the pump and then open the outlet valve, and if there is no pressure, it is time to leave, the sealing performance is not good, check where leakage, and perhaps your pump is broken
Q:Why should the water inlet of water pump be fitted with reducer?
In order to reduce the head loss of water pipe, avoid excessive suction vacuum suction pipe, usually larger than the diameter of the pump inlet diameter, must use reducer connection, installation reducer upper level, under the edge of the flow direction is rising, which can avoid the suction pipe does not accumulate gas.
Q:Yang Chengtai big, the pump power is too small, the water pump will be bad?
Related to water pump structure, when the pump head is higher than the rated pump head, the current will increase, the water discharged from the pump impeller, back to the inlet of water from between the impeller and the casing exceeds the rated value, if it is a high lift pump, clearance between the impeller and the casing is small, the water pump current increases with increasing lift, current too much faster than the rated value, the motor will burn; if it is a low lift pump design, when the clearance between the impeller and the casing of the strict requirements, and even some of the water pump, the outlet is blocked, the pump will not burn. The drinking water pump used on the table, generally used non-toxic latex diaphragm pump, the head is too much, will damage the diaphragm part, the motor because the circuit has protection, the motor is not easy to damage. Generally do not risk good, according to the actual situation, select the appropriate lift, suction pump.Yang Chengtai large! If the pump power is too small! The pump will break! But not necessarily bad, mainly determined by the pump structure.
Q:Pump house should be equipped with those equipment and valves
1. The inlet and outlet of the pump shall be equipped with a control valve, and the outlet shall be equipped with a check valve;2, lower than the pump suction the water tank, water pump entrance to bottom valve, and piping and valves equipped with irrigation. Or equipped with other water pump irrigation facilities.3, more than one pump system should have the total valve and contact valve.4, the corresponding control equipment.
Q:How can I pump the motor insulation?
A submersible pump to shake the insulation, water pump distance more than 20 meters away from the cable distribution box is fixed, at this time to shake the insulation in the distance distribution box can only shake, disconnect the power cable is connected with the shake table, the ground end is connected with the electric box so that the pump shell shake shake, also must be reliable grounding to shake to now, the pump shell grounding not only in the water, it must be a wire connected with a shell or a wire will be immersed in water, this is right insulating shake,
Q:In the design specifications, for example, the water pump requirement is two. What does that mean? Can 3 pumps be opened at once?
May not。Design is in accordance with the "two prepared" design, opened two units, has been able to meet the water supply requirements. And the electrical control parts are in accordance with the opening of two units, has been unable to meet the opening of 3 power distribution needs. The standby pump is only replaced when the running pump is out of order or needs downtime to maintain the water supply.
Q:What is the function of open circulating water pump and shutdown in thermal power plant?
Open pump and closed pump, circulating water pump seems to be the full name of the pump, the industrial pump is to provide industrial water. Both open and closed pumps provide cooling water on the side of the machine, just because the requirements for water quality are different. Closed water is desalted water, while open water is recycled water.
Q:Fire pump control cabinet installation distance, ground height should be how much?
30MC is fine. There are no definite rulesSome drawings of the introduction is explained, because the drainage of the water pump in the case of clogging, may be submerged into the water pump control cabinet, causing some unnecessary trouble
Q:Pump frequent start will reduce the service life, I ask what kind of frequency is called frequent start?
Personally think that the quality of different motors have different effects on the motor, you can try, try a minute it ruined his frequency is a / S
