the water treatment equipment shall be selected according to times of the relatively large water consumption per hour.
1 The discharge side of the pump must be equipped with a valve (ball valve or stop valve， etc.) and a check valve. The valve is used to regulate the operating point of the pump. The check valve can prevent the pump from reversing when the liquid flows back (the long shaft deep well pumps produced by our company are equipped with anti reversing check devices) and prevent the pump from being hit by water hammer
nBaltimore The supply of shaft seal water must be ensured. It is strictly prohibited to operate without water， otherwise the mechanical seal will be burned.
In order to maintain the original treated water volume without increasing the number of water pumps the liquid level in the storage tank can be increased by adjusting the floating ball in the liquid tank. After the liquid level in the storage tank is increased， the he QE curve of the device must move to the right. At this time， the head at the intersection of the two curves becomes smaller and the flow remains
RCape ude The WQ submersible sewage pump has compact overall structure small volume， low noise，Double suction pump remarkable energy-saving effect and convenient maintenance. It can work by diving into the water without building a pump house，portland Submersible sewage pumpFirst breakthrough in ecological and environmental protection greatly reducing the project cost.
Xx Unchanged.
Store in a well ventilated and dry place. If it is stored during idle period， the pump shall be slowly lifted from the water source and drained (especially in cold winter).
And it shall be used according to the quota specified in the manual.
l Slurry pumpInappropriate model is selected when selecting the pump. In actual use， when the load conditions do not match the model of the slurry pump， for example， the pump lift used is too high or too low， which will lead to overload， so we are selecting the pump
X The submersible sewage pump is a kind of pump product which is connected with the motor and works under the water at the same time. Compared with the general horizontal pump or vertical sewage pump， the submersible sewage pump obviously has the following advantages:Compact structure and small floor area. Submersible sewage pump is submerged
Lanalysis Change the oil: if the oil contains water， drain it，Double suction pump change the oil， seal the gasket， and then tighten the screw plug.
gM The submersible sewage pump is a kind of pump product which is connected with the motor and works under the water at the same time. Compared with the general horizontal pump or vertical sewage pump， whether there is sand deposition at the pool bottom， and whether it is necessary to cut off water and clear silt.
Slide evenly and slowly along the guide rail until the active coupling is in place. When the mobile device is selected， the hose shall be sleeved first， and the chain rope shall be threaded into the two lifting rings to lift the electric pump up and down. Be careful not to use the cable as a rope to avoid danger.
Inspection basise Ensure that the electric pump operates normally The electric pump needs to be equipped with a fully active water pump control cabinet when there are no other conditions. Do not directly connect the power grid or use a knife switch to connect the power supply.
T First， let&#;s talk about the familiar vertical slurry pumps. Here we refer to ZJL and SP submerged slurry pumps. Strictly speaking， the submersible slurry pump is also a vertical slurry pump， because its axis is basically vertical when it works，Double suction pump but it can be completely immersed in water when it runs， so it is a good choice
It can be divided into single slurry suction pump and double slurry suction pump; The second is that the slurry pumps can be classified according to the pump shaft and horizontal position of the slurry pump: horizontal slurry pump and vertical slurry pump. The horizontal slurry pumps of Panshi pump are mostly ah，portland Submersible sewage pumpFirst breakthrough in ecological and environmental protection AHR， HH and ZJ
eBaltimore Characteristic ysisStarting mode the starting mode of the water pump control cabinet is divided into: full pressure start， star delta step-down start， auto coupling step-down start， soft start and variable frequency start. Proper starting mode shall be selected according to power supply conditions and other factors.
tH Sewage; QW series submersible sewage pumps are generally equipped with an elbow， and then connect the water pipe as required. We call them mobile， which are mainly used temporarily or do not need to be fixed.
