Q:Why should the water inlet of water pump be fitted with reducer?
Increasing the pipe diameter can reduce the resistance loss along the path and reduce the suction vacuum of the pump! Before the inlet of the pump is a big diameter, when you reach the suction port, and the pump inlet diameter to be consistent, so the use of reducer joints!
Q:In the design specifications, for example, the water pump requirement is two. What does that mean? Can 3 pumps be opened at once?
Use 2 units and reserve 1 units. You can open 2 at the same time. Can three drive at the same time, depending on your water pipe layout, whether there are three sets of pipes, yes, three units open at the same time.
Q:Why can't vertical water pump use spring shock absorber?
Vertical pump can use spring shock absorber, because the bottom of the vertical pump installation area is small, so many people feel that it can not install spring shock absorber, actually not, and now there is a vertical pump can use the shock absorber;Introduction of spring shock absorber for vertical pump;1 、 spring cover and spring seat for the combination of butyl glue and cast iron, and after baking treatment, good weather resistance.2, according to simple installation, bolts can be used to adjust the height and level.3, can be matched with the pedestal design, can be used in various types of machinery and equipment.4, applicable to all types of pumps, fans, air conditioning boxes, pipes and so on.
Q:Water pump maintenance what should be maintained?
Bearings, seals, impellers - removing dirt
Q:Why should we pump water into a pump when the country uses a pump to pump it?
Because the leather cushion there is not completely sealed the water pump wall, there is a small gap in the contact, so that the piston up and down the air connection, air pressure is equal, can not pump water.And then add water to the gap closed, such upward pull the piston to make the piston below the space increases, but the air and can not go to fill the air pressure decreases, less than atmospheric pressure, only through inhalation of water to supplement water, which is forced by atmospheric pressure wells the water through the pipe and then rise to the pump. So it can be pumped up.
Q:What's the water pump?
Cooling water pumpDetermination of water replenishing pump1) the hourly flow is 4%~5% and the total water quantity is.2) the lift is the replenishment point and the pressure is plus 30~50 kPa.3] water pump to overcome the pressure of the replenishment point and the pressure difference between the make-up water tank, during which the pipeline is not long, you can ignore its resistance4) open system replenishment, no replenishment pump
Q:Why is the minimum liquid temperature allowed at 2 DEG C instead of 0?
It freezes at 0 degrees, and the pump runs and gets stuck.
Q:Domestic pump automatic shut off the water, but also turn around, stop what happened?
You can find a water pump factory people ask, ah, Baidu, find a corporate website, many have online advice. By the way, a site called water industry navigation, pump manufacturers included a lot, and find it may be faster.
Q:Fully automatic self-priming pump
Yes, design according to your different working conditions. For example, water pressure pump is pressure control, water pressure is low will automatically start, the pressure automatically shut down.
Q:How to change the frequency of a water pump with a pump?
I have encountered this problem, 1, check the reverse pump outlet single flow valve is damaged2. Check whether the three wires of the motor are in wrong position and reverse when starting
