Product Description:

ALD vertical multistage centrifugal pumps are newly developed products to cater for the water supply and discharge in high-rise constructions to the standard of National Fire Bureau GB6245-98.Because of the use of the advanced energy-saving hydraulic model to feature high efficiency and wide performance range; they may better meet the operation requirements of users. Besides, they are structured vertical or segmental to feature safe and stable operation, long service life, small occupation space and easy installation and maintenance.

Working Conditions:
1、 Used to deliver clean water of non-corrosive medium similar to clean water in physical and chemical properties, with the volume of solid insoluble not exceeding 0.1% of unit volume. To deliver medium containing small particles, please specify when placing an order.
2、 Temperature of medium:-15℃~+120℃
3、 Maximum system working pressure not exceeding 2.5MPa.
4、 Ambient temperature shall be lower than 40℃, and relative humidity lower than 95%.

Q:Fully automatic self-priming pump
Yes, add a water level controller.Try electronic water level switch with stable and reliable performance. In Baidu search "electronic water level switch official website", you can find more information, model is BZ201
Q:50 meters deep well with what water pump: home?
For deepwater submersible pumps, ordinary submersible pumps are inefficient.
Q:What's the difference between a cold water pump and a hot water pump?
Cold water pump refers to the pump can be transported below 80 degrees C temperature liquid, known as cold water pump, between 80 degrees C to 120 degrees C, the temperature of the pump is called hot water pump.1, the characteristics of hot water pumpHot water pumps IRG hot water pump which is based on ISG and ISW centrifugal pump series on optimization designed, especially IRG type hot water circulating pump consumption, because the pump adopts a vertical motor is installed in the upper part, and a short frame between the pump and motor, not because of a mechanical seal Water Leakage phenomenon the motor inside the water inlet of the motor burn, but also in the IRG based on the design of the hot water pump mechanical seal in high temperature hot water pump maximum temperature by external tap water cooling device can reach 240 DEG C.2, the characteristics of cold water pumpSeal packing seal or mechanical seal rubber material Ding Qing cold water pump commonly used, the most common packing pump is IS single stage single suction centrifugal pump of the pump is also one of the earliest water pump products, because the filler itself requires liquid cooling and lubricating the pump temperature as the only 80 degrees, and packing seal cold water pump and dripping phenomenon has pollution to the pump body pump base and the surrounding environment, this kind of product has been ISG and ISW centrifugal pump series products replaced, ISG and ISW series of cold water with mechanical seal it has no water leakage phenomenon, and is directly connected with the impeller structure used in the the shaft of the motor, the noise and vibration above is obviously better than that of the old type of IS series cold water pump this kind of pump products commonly used in air conditioning water cycle with so called air conditioning chilled water circulating pump.
Q:Does the water pump pump the coolant into the engine or pump it out?
Strictly speaking, the pump is powered cooling fluid circulation, which is pumped into and out of the water pump is to rely on to complete the engine, the water tank and the pipelines are connected to form a closed loop, the engine cooling water tank, heat release, heat exchange by circulating cooling liquid, and let the power coolant flow up from the water, like the human heart as the power of the arteries and veins are provided by the contraction and relaxation of the heart of the.
Q:What is the difference between a low pressure pump and a high pressure pump?
The specific speed of the high pressure pump is relatively smaller than the speed.Lift is not the same, the same flow, high pressure pump head high.Pump and shaft materials are not the same, high pressure pump raw material demand is higher, to be able to accept greater pressure and torque.The size is different, the pump body of high pressure pump is larger.Bearings can also be different, low pressure pumps are rolling bearings, and high pressure pump power, then some pumps are selected sliding bearings.The support method can also be different, the low-pressure pump is the pump foot support, but the high pressure pump can be the intermediate support.
Q:Is there a water pump with its own flow regulating function?
Pump with adjustable flow depends on your useThe ordinary displacement pump, which has a small flow rate, can set the flow rate per second into the system and is widely used in the laboratory.Large flow regulating flow pump is mainly variable frequency pump, through the electrical signal feedback regulation, change the pump water storage flow.The main thing is to see your flow, and then determine what you want to pump!
Q:A direct type pump model with the coupling type, what is the difference?
The direct type shall be the same shaft of the pump and the motor, and the connecting shaft is a pump and the motor shall be 2 shafts, and shall be connected by a shaft coupling.
Q:TDH what units are present in the pump parameters?
In the pump parameters, TDH is the head of President (Ying Chi).The formula is as follows:TDH (Ying Chi) = total head (Ying Chi) = (- water pressure readings + drainage pressure gauge (drainage dynamic head - water head + (drainage pressure gauge - water pressure elevation correction table elevation correction)
Q:What are the commonly used tools for repairing water pumps?
Because had done a mechanic, and relates to a pump, not including motor repair, commonly used tools: pliers, pliers, adjustable wrench, wrench, screwdriver, bench drill, multimeter, electric iron, Lamar, hammer, ruler, chisel. Commonly used parts: bearings, impellers, screws, terminals, lubricants and so on.
Q:Explore the flow of water pump production process is like?
You should go to the water pump factory visit, than to a vivid books. General settings are specific parameters - three view - model making - modification - Roughing - semi finishing - finishing - material quenching - heat treatment - carburizing - Black - assembly - spray painting - Inspection - Labelling - packaging.
