Product Description:

SLQS series single stage dual suction split casing powerful self suction centrifugal pump is a patent product developed in this Co.for helping users to settle the difficult problem in the installation of pipeline engineering and equipped with a self suction device on the basis of the original dual suction pump to make the pump to have the exhaust and water-suction capacity. AS of the existing centrifugal pump unit, the user has to do one of the three jobs below when to get the pump suck and start working:
1.mount a foot valve on the water suction pool of the inlet pipeline and close it before starting the pump, then open it when the pump is full of water inside and the air inside is completely exhausted. Under-liquid installation of the foot valve makes overhaul very unconvenient in case of a failure.
2.equip the pump unit with a vacuum pump to lead the water in the suction pool into the pump. Different norms of the pump unit need different norms of the vacuum pump, requiring
a cost not low and thus increasing the engineering cost.
3.mount the pump unit under the sucked in liquid surface,i.e. Inverse pumping, that means the basis of the pump room must be below the ground, i.e. digging hole underground,this makes the engineering cost greatly increased. While the powerful self-suction centrifugal pump can make it satisfied for a user to have the pump normally pumping without use of any of the three ways above-mentioned!
Similar to the common dual suction pump, this series pump is also suitable for a water works, air-conditioning water circulating system, water supply of buildings, irrigation, water draining pump station, electric station, industrial water supply system, Shipping industry etc. To transport pure water or the Liquid of both physical and chemical natures similar to Pure
water.
The series pump have attained 7 kind of patents.
Notice: if it is with mechanical seal devices,the external washing water should be adopted.

Q:Harm of air pump and pump
Minimum starting current when centrifugal pump of such a small impact on the grid but long closed operation will make the liquid in the pump to the pump overheating temperature is too high will lead to the problem of the seal to a certain temperature will cause deterioration of oil bearing bearing caused by excessive wear and even bite dead
Q:How does the centrifugal pump pump and cut the pump?
Check the motor, pump and fasteners in good condition; whether the lubricant is added or not;Disc dynamic coupling, whether or not stuck phenomenon;Open the inlet valve, remove the gas in the pump or pump the gas out of the pump;
Q:Why does the centrifugal pump close the pressure to start?
The motor power is selected according to the rated flow of shaft power points plus 15 to 25%, if the outlet valve is fully open to start, the pump flow may deviate from the amount of fixed lot, pump efficiency also reduces a lot, resulting in shaft power greater than the motor power caused by tripping even burned electric machine.
Q:What is a positive displacement pump? He Weizheng displacement?
The principle and structure of positive displacement pumps are similar to those of hydraulic motors. Positive displacement is the pump outward to provide flow and pressure, that is, conventional pumps. A negative displacement pump is a hydraulic motor that rotates by external pressure and flow.
Q:How do vacuum pumps and pumps work together?
The role of the check valve:"[the water pump impeller is not closed" refers to the pump suction pump before the water without water inlet pipe and water outlet pipe gas should be connected] is a connector, a connector, still can make the level surface, in order to prevent the water flow along the pipe, until it reaches the level of the flush, then increased check valve, or pumping up water will not leak?Vacuum suction principle of self suction pump:Assuming that the pump connected with the water inlet of a sealed container, the container has plenty of water, since the start of a water pump, water is thrown out of the water impeller pump body, water inlet seal vessel due to the extraction of water to form a vacuum cavity, this assumption will be connected to vacuum cavity and exposed to atmospheric conditions of water, water at atmospheric pressure under the effect of entry into the vacuum chamber".....
Q:Suction stroke and lift of water pump
For example: there is a kind of water pump, the model is called "BSP" series, the volume is not large, but the nominal suction process can be 4 meters, it can not add water to 4 meters, it is considered to be relatively high in the micro pumpIn micro pumps, not all pumps have self-priming capacity ("suction stroke")Some centrifugal pumps there is no self-priming ability to use must first do add water. Although some micro pump with self absorption capacity, but "suction" are often the subject of "and the water inlet pipe in all air, can smoke the vertical height of water gap, even only half not so. The pump selection, the absorption process is a relatively important parameter.
Q:What does "efficiency" mean in a water pump catalog?
General pump efficiency is 60% ~ 85%. high efficiency of the pump, indicating the same work, the pump consumes the lowest energy, and vice versa
Q:What's the difference between a centrifugal pump and a centrifugal pump? What are they used for?
As the name suggests, centrifuges are machines that achieve centrifugal effects by centrifugal action. And you say the centrifugal pump is only specific, and the same as the pump
Q:What is the working pressure of the hydraulic pump in the hydraulic transmission system?
The operating pressure of the hydraulic system depends mainly on the load. Generally speaking, the working pressure of the hydraulic system means the highest working pressure of the system. If the pressure is higher than the value of the equipment, the relief valve works to relieve pressure. The actual working pressure of the hydraulic system is determined by the load, which refers to the actual pressure of the hydraulic oil and can be read directly from the pressure gauge. The pressure increases with the increase of the load. You Li's balance can know: the thrust of the cylinder = the load, the thrust of the cylinder = the working pressure of the hydraulic oil, the working area of the cylinder, the working pressure = the load / the area of the cylinder.
Q:Direct connection pump What is straight pump and non direct pump? What's the difference in structure?
What is straight pump and non direct pump? Direct coupled pump shaft and the motor shaft is directly coupled with the coupling and non direct coupled pump: pump shaft and motor shaft through the belt pulley, V-belt connection or other forms of transmission. What is the difference in the structure: the direct coupled pump has the advantages of compact structure, simple installation, but the relatively small power; non direct coupled pump: pump and motor is independent, the two transfer torque through the belt, the structure is relatively large, complex installation, general power is relatively large.
