Horizontal Constant Pressure Fire Pumps XBD-HL Series

Description:

XBD-H series vertical (horizontal) variable-flow constant-pressure fire pump. a new developed product is the third generation based on XBD-HY(TB)series variable-flow constant-pressure fire pump. Combined with advanced technologies from America and Switzerland, and guided by famous professors from Jiangsu University of Science and Technology. Compared with the original tangent fire pump, it is more advanced because it's original in designing in accordance with the principle of the partial emission pump so that its performance and technical conditions are in full conformity with requirements in G6245-1988 Performance Requirements and Testing Methods for Fire Pump newly released by the state.

XBD-H series variable-flow constant-pressure fire pump is mainly used for fixed fire systems in industrial and civil buildings, such as hydrant, automatic sprinkler and water spraying fire extinguishing systems, as well as for water supply systems for domestic sue ,fire control and public domestic sue ,water supply for buildings, civil works, industrial and mining uses, boiler and so on.

Q: I do pump sales ~ only to enter the line soon ~ often asked how many levels of motor? I can't recognize myself! So ask for advice here: 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: where t is in minutes since the pump is started. If the holding tank contains 1000 liters of water when the pump is started, how much water does it hold one hour later?: Water is pumped out of a holding tank at a rate of 4-4e^(-.14t) liters/minute. Lets call that function w(t). So if we integrate w(t) over a time period that will give us the total water removed over that time period. So lets integrate it from t=0 (time when pump started) to t=60 (one hour later): ∫ w(t) from t=0 to t=60 ∫ w(t)=∫ 4-4e^(-.14t)=4t+(4/.14)e^(-.14t) evaluated from 0 to 60 ∫ w(t)=4(60)+(4/.14)e^(-.14*60)-4(0)-(4/.1... ∫ w(t)=211.435 liters removed If the holding tank began at 1000 liters and 211.435 were removed... Remaining water=1000-211.435 ***Remaining water=788.565 liters***

Q: motor overheats but no leak. water just boils in resorvoir. is it hard to do it on my own?: Water pumps have whats called a weep hole, if it's going the weep hole will leak coolant, Could be the belt on the waterpump is not tight eneough to turn the pully.

Q: The at is a 2003 Toyota celica. And how much would it cost to get the water pump and timing belt replaced?: It’s useless to try and get an estimate for the cost of parts and labor for repairs via Yahoo Answers. In a lot of cases we have no idea of what country you’re in, let alone city, state, province or township. Even knowing where you live is of little use as prices for parts and labor can vary wildly within the same area. If you understand the problem and just need parts you can Google for the best prices for parts. Your best solution for getting an estimate of repair costs is by contacting an independent auto repair shop in your area. Don’t go with any of the franchise or chain type auto repair places as they frequently use poorly trained help and many have no mechanical training at all, and dealers have to charge more to cover their high overhead. It’s really best (when possible) to get a personal referral from someone you trust to a local independent shop.

Q: my water pump went bad on my 1997 chevy cavalier, causing it to leak all the coolant it had in the system. i put water in it til i could get new water pump. changed out water pump. attempted getting air out of system. put more concentrated coolant in system than i did water. bad guessing on my part. ran car around block 5 times. it was fine. this morning on the way to work, it started overheating again. my thoughts : more air in system that's not coming out? thermostat REALLY went bad at same time as water pump???? overheating all because of a little too much coolant??? for some crazy reason, my system needs to be suddenly flushed? Your thoughts? one last thing, the car has always ran perfectly normal temp til water pump went bad.: sounds like a air block in the cooling system. leave the radiator cap off and start it. the air will push the antifreeze out but once the air is out it will start to circulate. you will have to add more antifreeze before putting the cap back on. don,t forget to add some to the reservoir.

Q: We use this water pump for about 2 years, and in the last week the circuit breaker trip when we turn on the pump. What should I check first for the problem?: It seems that your breaker has tendency become weak, first I would replace the breaker with a new one of the same amperage. You may have a filter on the supply pipe and if clogged it will draw more.

Q: I Need a water pump, no matter its fountain pump or high stream pump. But the things or you can say the parameters i required in that pump is, 2 inch minimum outlet from where the water come out, pressure 130 or above (in PSI) runs wid a 1 or 2 Horse Powered motor not more then 2HP. And the pressure calculation is flow of the water (130 Psi) , like while water is streaming out.Any one who can sugest some water pumps which can fulfill or near or above to my requirements. thanks alot sir for you kind time.: there okorder

Q: We have 2 1995 E320's that are heating up way too high when running. One has been diagnosed at the repair shop for a malfunctioning fan clutch. They also said that as the car was running hot the water pump and thermostat should also be replaced (??) The water pump is 5.5 hours of labor and I cannot afford it right now. I was wondering how hard to replace it myself. Thanks: I have a 94 E320 in the shop right now with the same issue , running hot but not overheating and i wouldn't even consider replacing the water pump cause i have found the fan clutch not engaging at all . and you need a second opinion . is it possible for a water pump to cause this issue ....yes....is it likely.....NO if the fan clutch is engaging and the car still runs hot but does not overheat the thermostat is most likely not opening completely (sticking) and not allowing proper coolant flow . or you may have an inaccurate CTS .(coolant temp sensor) either way find a place who can properly diagnose your car . i hope this helps you

Q: I have an ls vtec set up on my 89 EF si, I want to install a better oil and water pump. I m thinking of going with GSR. BUt my question is are all years gsr oil, water pump the same? I think my ls Block is from 93-95 acura. which year gsr water oil pump can I use for my motor?. also I have a 2000 si head. do I have to change the timing belt? and Last question is should I use b16, gsr type r pumps? I heard gsr and type r have the same part #. Thanks: you need the GSR/Type-R water pump. This is one of the major causes of LS/VTEC failure. The GSR/Type-R has 22 teeth while the LS/GS has 19 teeth. The extra teeth cause it to spin faster pushing more water through the system. Any time you change something related that uses the timing belt, I ALWAYS install a new timing belt, and tensioner. That way there are no worries later.

Q: I have replaced my water heater and water pump because the owner before me didnt drain it over the winter... but know the water suputers when the pump is on.. when I hook up to city water it works great.. I have not been able to find any leaks.. any ideas???: A lot of the pumps for RVs do cause a slight sputter, Try compleatly filling the water tank, then turning the pump on,. Allow a few minutes to build up pressure and fill the hot water tank, If the sputtering slows, or compleatly stops, your ok. You have to remember that a lot of after market pumps don't work quite as well as an OEM pump. If it's a real bad sputtering, You might need to return the pump.
