Products Overview of Non-negative Pressure Water Supply System
1. no negative pressure (no suction) automatic water supply equipment directly use the municipal pipeline network as water source, forming a continuous airtight relay pressurization water supply patterns, completely avoid lowering the water quality caused by the traditional secondary pressurization water supply system, completely ensure the water quality of the municipal water.
2. make full use of municipal water pressure itselfe, make up the pressure difference, effectively and maximize the frequency conversion effect.
3. traditional secondary pressurized water supply way, the water is tapped into reservoir, which leads to original pressure wasted and reduces the neighboring user pressure, while this equipment directly fill pressure to original water pressure, so as to realize the optimal limited pressurization, guarantee the adjacent pipe pressure was not affected.
Performance Characteristics of Non-negative Pressure Water Supply System
1, directly connected with the municipal pipeline, no reservior needed.
2, small volume, occupies little space, convenient installation.
3, water tank, pumps are made of stainless steel, no secondary pollution.
5, the water pressure is steady, won't cause adjacent user pipe pressure fluctuations.

- Q:What's the difference between a double suction pump and a single suction pump?
- From the literal sense to understand, double suction pump is the impeller at both ends of the water inlet, and the single suction pump is from the impeller at one end of the water.Dual suction is mainly used in the process of large flow and low lift. When the pump flow is greater than or equal to 280m3/h, the caliber of 200mm or more, if the use of a single suction pump, then the speed requirements of about 1450rpm in order to achieve the suction requirements. However, if the double suction pump is used, the size and weight of the pump are reduced, and the speed can be increased, the volumetric efficiency is increased, and the reliability of the equipment is improved.Single suction pump, also known as end suction pump, single suction pump flow is relatively small. The same flow, single suction of small size, but the axial force, bearing a large burden. The cost of single suction pump is low, the price is reasonable, widely used, but in many ways it is not as good as double suction pump. If the inlet pressure is higher, the general choice of double suction wheel can be solved. Because the axial force balance of the impeller of the single suction pump is a big problem.
- Q:I have a 1992 Pontiac Sunbird LE. It has 4 cyl. and it has 98,000+ miles on it. I took it in to get the oil changed and they inspected the car for a noise it was making. Found out the water pump was gone and the timing belt was worn. Need replacement on both. They quoted me 670.00 for the repair! STEEP! The part should cost about 20.00 max. How do I replace the water pump myself? And the timing belt? Do I need special tools? If I can't do it pretty easily myself, how much should I pay for the repair? I'm not made of money, but I need my car to run to get me to work everyday! I can't afford much, so anything around 200-300 is probably the most I can spend on the repair. What should I do?
- On okorder , your timing belt with cost $15.99 and your water pump will cost $35.19 for a new one. Keep in mind that most shops charge more than that as this is how they make a profit. Depending on what their labor charge is, that doesn't sound too far out of line. I just did a timing belt and water pump on a Chrylser with a 3.5 today and it cost about $600 to do that. The water pump on your car is driven by the timing belt and is not an easy task to accomplish if you have no idea what you are doing. You can easily destroy this engine. If you are not sure how to replace an air filter, this would definately be out of range.
- Q:I just had the water pump replaced, now less than a week later it is overheating again and sometimes blowing cold air. What does this sound like it would be?
- Thermostat.
- Q:yesterday the electric went out for a while we had some big storms and now the water doesnt work, the pump is running but there is no water coming out, i need help on how to fix it, please. hurry
- You might need a new foot valve. That keeps the water from draining back into the well. Depending on what type of pump you have, could be at the bottom of the well. To bleed the well, you need to remove the plug on the motor...it looks like a nut...about 3/4. You remove that and fill with water...when its full, turn the pump on and keep filling it till it gushes out...put the plug in (with new teflon tape) and it should work. Be careful not to touch the electrical, could get shocked. Its easy if the foot valve is good.
- Q:i used my water fountain pump for the first time yesterday and I've had it for 10 years and i used it yesterday it worked with the water and everything was fine!then the next day i wanted to turn it on , it went on it started vibrating but it wasn't pumpingwhen i had it on the other day the water was dirty but it was workingi cleaned it the filtershould i put vinegar to clean it ?and what else should i do!??? Help :#92;thank you!

- Q:Two sewage pumps switch from each other, start with float switch control, the first sump, when the water is full, the first start, the second rotation to second units start, so the cycle of alternating
- The puddle is full, the float switch is closed, and the relay J1 works to drive the first motor. The J1's work makes the intermediate relay 'J' work and locks itself, preparing for the work of the second machines. The water level is lowered to the required minimum position, the ball is broken, the motor is stopped and the motor is stopped. When the water level rose to the highest position again, the floating ball closed again, the relay J2 and self-locking relay J2 to drive second motors, instant intermediate relay are opened, when the water level again be reduced to the lowest position, float off, the motor stops working, stop by working in front of the intermediate relay. The whole circuit back to the original state. So that the two motors work alternately.It should be noted that the circuit diagram for simple to understand, only painted the control circuit, there is no main circuit, there is no missing phase, leakage, over-current and other protection, the actual installation needs to be installed. There is the role of time relay is to ensure that the relay J2 normal work, the intermediate relay is disconnected, so that the motor 2 does not occur wrong action, time relay can be set to a few seconds, or even less than a second. Intermediate relay can also be controlled by time relay, and its time is also set very small, so as to avoid J2 short time possible power supply.
- Q:it just go? I was told that my water pump had leaked at least for awhile before it went and if it had been in the garage someone competent should have noticed it. Then other people have told me No it just goes.whats accurate?
- You can have a small leak for a long time before a complete failure. Some cars, it's harder to inspect the front of the block than others. It's possible that even a good mechanic wouldn't have noticed it if all he's doing is a quick oil change. You might have noticed it yourself: a water pump leak would leave you with a sweet smell after you park. You might even notice it while driving, if the fumes get pulled into the car.
- Q:My car is 3 years old and it only has 18,000 miles on it and I just got it back from the repair shop at the dealership because the water pump broke. They replaced the water pump and something else that was recalled. But I looked online and found water pumps should last a long time. What might have happened to it, and what would cause it to break?
- sometimes crap breaks. if this water pump lasts 18,000 then you have a serious design flaw.. or you are doing something as the driver to break it. But sometimes you get a dud, it happens. not to worry. that's why you get a new car, warranty is awesome.
- Q:Water pump 50HZ impeller and 60HZ what is different, why not the same?
- 50HZ motors are usually not damaged if they run on a 60HZ circuit, but the speed will increaseConversely, the 60HZ device runs on the 50HZ circuit, and the speed drops.Because of their different frequency, make them synchronous speed rotating magnetic field winding is different, so the rotor induction (induction motor) speed will be different, the pump will naturally lift Gao Shaoxu, and often will not cause damage to the equipment, because many things are in the 50HZ 60HZ.Second, for synchronous motors, the increase and decrease of speed is much more obvious than that of induction motors, because their rotor and motor are synchronous and keep synchronous speed
- Q:i installed a new pump don't know how to increase water pressure and to what what pressure it should be set
- This is very simple i would sugest the pressure to be set betwene 60 to 70 NO MORE THAN 70. 1. turn off power to pump (ether the circut breaker or a switch near the pressure switch) you dont want to weld the wrench to the switch. 2. remove the cover to the pressure switch its self (usly one #2 phillips screw) 3. now you will see 4 wires under some sloted screws nearest to the front of the switch, behint that is 1 or 2 bolts with a spring and a nut. 4. if you see 2 bolts you will want to turn the nut on the larger one to the right. you will want to tighten it about 1 to 2 full turns. (the same goes if there is only one bolt also) 5. now open the valve that is on the tank untill you here the switch click. then close the valve. 6. turn the power back on tio the pump and watch the pressure gauge on the tank. i DO NOT RECOMEND MORE THAN 70PSI. 7. if it goes over the pressure you want repete steps above exept loosen the nut in about 1/4 to 1/2 turns untill you reach the desired pressure 8. if it does not reach your desired pressure then you do the same thing exept tighten the nut in 1/4 to 1/2 turns untill you attain your desired pressure. 9. when the pressure is reached, replace cover so you dont risk rusting the contacts. if you need more help feel free to email me. and i will assist you in any way that i can.
