Q:What's the difference between a cold water pump and a hot water pump?
Cold water pump refers to the pump can be transported below 80 degrees C temperature liquid, known as cold water pump, between 80 degrees C to 120 degrees C, the temperature of the pump is called hot water pump.1, the characteristics of hot water pumpHot water pumps IRG hot water pump which is based on ISG and ISW centrifugal pump series on optimization designed, especially IRG type hot water circulating pump consumption, because the pump adopts a vertical motor is installed in the upper part, and a short frame between the pump and motor, not because of a mechanical seal Water Leakage phenomenon the motor inside the water inlet of the motor burn, but also in the IRG based on the design of the hot water pump mechanical seal in high temperature hot water pump maximum temperature by external tap water cooling device can reach 240 DEG C.2, the characteristics of cold water pumpSeal packing seal or mechanical seal rubber material Ding Qing cold water pump commonly used, the most common packing pump is IS single stage single suction centrifugal pump of the pump is also one of the earliest water pump products, because the filler itself requires liquid cooling and lubricating the pump temperature as the only 80 degrees, and packing seal cold water pump and dripping phenomenon has pollution to the pump body pump base and the surrounding environment, this kind of product has been ISG and ISW centrifugal pump series products replaced, ISG and ISW series of cold water with mechanical seal it has no water leakage phenomenon, and is directly connected with the impeller structure used in the the shaft of the motor, the noise and vibration above is obviously better than that of the old type of IS series cold water pump this kind of pump products commonly used in air conditioning water cycle with so called air conditioning chilled water circulating pump.
Q:What are the categories of pumps?
First, select the pump to meet the requirements of the headThe so-called head refers to the required lift, and not lift the water height, clear this point, the choice of water pumps is particularly important. Pump lift is about 1.15 to 1.20 times the height of lifting water. If the vertical height of a water source to the water is 20 meters, the required lift is about 23~24 meters. When selecting a pump, the pump head should be close to the required head, and the general deviation is not more than 20%. In this case, the efficiency of the pump is the highest, and it is more energy efficient, and the use will be more economical. If the lift on the nameplate is much smaller than the required lift, the pump can not meet the needs of users, even if the water can be pumped, the water is also very poor. But in turn, the high lift pump for low head, there will be heavy traffic, resulting in motor overload, if long time operation, the motor temperature, the winding insulation layer will gradually aging, and even burning motor.Two, select the appropriate flow pumpWater pump flow, that is, the amount of water is generally not too large election, otherwise it will increase the cost of water pumps. Should be selected as needed, such as the use of the user's family self-priming pump, the flow should be chosen as small as possible; if users use the submersible pump irrigation, you can properly select a larger flow.
Q:How to introduce water pump?
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 of technical parameters are flow, suction, lift, shaft power, water power, efficiency, etc.; according to the different principles of work can be divided into volume pumps, vane pumps and other types. Displacement pump is to use its studio volume changes to transfer energy; vane pump is to use the rotating blade and water interaction to transfer energy, there are centrifugal pumps, axial flow pumps and mixed flow pumps and other types.A pump is a machine that transports liquids or pumps liquids.

Displacement pump is to use its studio volume changes to transfer energy; vane pump is to use the rotating blade and water interaction to transfer energy, there are centrifugal pumps, axial flow pumps and mixed flow pumps and other types.1, displacement pump: the use of working chamber volume changes in the period to transport liquid.2: vane pump: the use of blades and liquid interaction to transport liquid.
Q:What is the difference between self-priming and non self suction?
The self-priming condition of the centrifugal pump is that a small water tank is attached to the pump body. Don't use water every time you start. No suction, no water tank. And the use of volumetric Self-priming pumps, such as car cleaning, high-pressure pumps are in this category.
Q:What does water pump mean?
According to use: - water pump, pump, slurry pump, sewage pump, sewage pump, well pump, submersible pump, pump, pump, fire pump and other household. It's a device for pumping liquid.
Q:What is the reason that the water supply of pump is getting smaller?
1, the water pump screen plug, should remove the filter screen sundries.2, the use of lift is too high. Over the pump range, the pump should be adjusted to use height or replace the pump head.3, pump impeller plug or wear, should remove the impeller sundry. Replace the impeller if worn.4, pump outlet pipe blocked by debris, should remove the debris in the pipe outlet.5, diameter and pump does not match, replace the outlet pipe.6, the pump cover gap is too large, increased pump volume loss, should adjust the gap.7, pump body and pump cover leakage, should tighten the pump cover screw, make the pump body and pump cover close coordination.8, the pump speed is low, the use of voltage is too low. Should adjust the voltage to the rated value, replace the thicker cable or avoid peak use.9, water pump diving depth is too shallow, there is air intake, should adjust the diving depth. Pump running depth is not less than 0.5 meters.Yi Mai water pump to help you answer, I hope to help you
Q:How do I calculate the power of the pump?
Power P (kw) =9.81*Q (second cubic meter) *H (head, unit m) / efficiency;The efficiency can be found on the pump nameplate or sample.This is the rated power, if the head down, the flow increases, the power will increase, so the actual motor power is often much larger than this calculation.Generally buy pumps are equipped with motors, manufacturers can refer to the same model or similar models of motor power.
Q:Stop the engine immediately and stop the circulating pump and the condensate pump. What's the harm to the turbine?
The condensed water is also used to air pumping device, steam seal cooler as cooling water, according to rules of turn.The circulating water is also used to supply cooling water to the oil cooler, and the oil temperature will rise.Hazard: exhaust pipe, condensate pipe will burst tube, low pressure cylinder rising temperature for deformation, rotor (shaft seal) may be deformed.
Q:What's the submersible pump?
Zhengzhou sea diving pump. Deep well submersible pump is a fountain, drinking water transportation, irrigation, hot springs, high-rise transport facilities, etc., deep well submersible pump excellent performance, so widely used in various fields.
Q:What is called soft start of water pump?
Close the outlet valve of the pump, open the inlet valve, and can ensure that the water pump "self filling" (the liquid level is higher than the pump inlet pipe under the condition of the water pump start procedure is: to start the motor, to the normal operation of the motor, slowly open the outlet valve, the current gradually increase. But in the unattended operation (valve), and automatically pump, and pipeline diameter and length (in the pipeline water quality will be great), such as the motor start fast, to quickly promote the quality of water (as the train will soon accelerate acceleration), will make the motor starting current is large, causing the motor to trip and the damage of mechanical and electrical. Soft start (soft starter added in the circuit) - that is, slow motor speed, can overcome the above situation.Stop the pump normal order is: close the outlet valve, then stop the motor, such as unmanned operation, the outlet valve is not closed, when the pump stops suddenly, the water inside the tubes (especially vertical pipe), water will quickly turn back, so when the check valve suddenly closed, the fast flowing water suddenly stop by the inertial impact that produces "water hammer" effect and damage of pipeline system, using the "soft stop" should, in the circuit is connected with the soft stop device.
