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:What are the new regulations in the design of main and auxiliary water bin and water pump room in coal mine?
The main water bin must have a main bin and an auxiliary warehouse. When a sump is cleaned, another water tank can be used normally.When the normal water inflow is below 1000m3/h, the effective capacity of the main water tank should be able to accommodate the normal discharge of 8h.The effective capacity of the main water bin can be calculated by pressing type in the mine where the normal water inflow is greater than 1000m3/h:V = 2 (Q+3000)Effective capacity of V-- main water bin in type m3;Q-- mine hourly normal water inflow, m3.However, the total effective capacity of the main water storage tanks shall not be less than the normal water inflow of 4h.The effective capacity of the water tank in the mining area shall be able to accommodate the normal water inflow in the 4H mining area.There is a big difference between the maximum water inflow and the normal water inflow in the mine. The drainage capacity and the water storage capacity should be specially designed.The water inlet chamber should be set up. A sedimentation tank shall be provided for the filling of water sand, hydraulic coal mining and other gushing water with a large amount of impurities. The water storage capacity of short positions must often remain above 50% of total capacity.
Q:What's the difference between a cold water pump and a hot water pump?
Water seal and sealing quality is different?
Q:Pump adapter joint net outside tube, what is the principle?
At once the room after the fire, the internal fire pool once water shortage, the water tank can be within the fire truck hit the water chamber through the pump adapter connected to the fire extinguishing effect.
Q:Explore the flow of water pump production process is like?
You should go to the water pump factory visit, than to a vivid books. General settings are specific parameters - three view - model making - modification - Roughing - semi finishing - finishing - material quenching - heat treatment - carburizing - Black - assembly - spray painting - Inspection - Labelling - packaging.
Q:How to identify the motor series of pumps
Look at the speed, see the modelFor example, the actual 1430r/min synchronous speed is 1500 rpm, the speed formula: speed = time (60 seconds) * frequency (50HZ) divided by the number of pole pairs one pole of 2 pole, which can be calculated 3000 83019 1500=2 on pole or 4 pole motor.See model is more straightforward: for example motor model is Y 132 M- 4Y, three-phase asynchronous motor, the three-phase asynchronous motor product name: YR for winding type asynchronous motor; YB explosion-proof induction motor; YQ high starting torque of asynchronous motor.  132, a high center (mm)M code, frame length4, the number of polesFrom the motor nameplate marked, you can see that the motor is 2, model FW12-2, speed 2840
Q:Why is the water pump smaller than the pipe diameter?
In order to reduce the water outlet resistance of pump outlet.The statement should be: if your pump has been selected, then the outer outlet pipe caliber than the water pump outlet diameter one.
Q:How do I know the pump pressure?
The "H=100M" in the parameter is the pressure index of the pump. "H" is the height of the head and the height of 100m. Since the 10M lift is approximately equal to 1Kg/cm2 pressure. Your pump is 10Kg/cm2 pressure.Q=18 M3/H, that is, 18 cubic meters of traffic per hour;H=100M, that is, rated head 100M, high head;P=4.0 KW, that is, the motor power is 4 kw.
Q:2 pumps parallel, lift the same, pump head is not stacked?
2 pumps parallel, lift the same, pump head is not stacked?;Answer: the head can not be superimposed, that is, a lift and a pump, but the pumping speed (flow) is two times a taiwan.2 pumps in series, the same flow, pump head is not stacked?.Answer: the head can be superimposed, that is, the pump head is two times as much as a pump, but the pump speed is the same as that of a pump.
Q:The role of water replenishing pump in circulating system
In the circulatory system, the replenishment pump acts as a means of circulating water to the heating system and to supplement the water lost by the circulatory system. Most heating systems use a constant pressure pump to ensure that users of any degree of the system can normally cycle hot water.The fire unit is normally there are many, including the general use of the unit: water supply pump, fire pump, filling, pressure relief valve, pressure sensor, one-way valve, fire tank must maintain the required pressure, when the pressure drop or leak, the pressure sensor will fire a signal to the irrigation control cabinet, and control the cabinet module will give a water pump signal, such as a water pump after receiving the signal will immediately start running, to the fire in the irrigation water, irrigation water until the fire to the set pressure, the fire control cabinet will give irrigation pressure sensor signal, let the water pump will automatically stop running. Water pump and pressure regulating pump the same principle, are used for replenishment pressure.
