Product Description:

Conventionally, the discharge of domestic sewage in the construction basement, when sewage is unable to flow into sewage pipeline by gravity itself, there shall be provided with sewage collecting basin and sewage pump to discharge it to outdoor manhole. But this type of sewage discharge embodies many drawbacks in practical application, such as dirt easily deposited and clogged, need of regular manual cleaning, sewage pump often blocked and damaged by impurities, pollution to ambient environment by the foul smell during cleaning, and so on. Therefore, this type of sewage discharge has been proven nonideal.

WQP sewage powerful discharge equipment is a new generation product developed by our technical R&D personnel. It takes into consideration of the practical application conditions on site and focuses on the objectives to be economical, practical, environmental friendly and highly effective. It uses its filtration function to make the impurities and solid particles contained in sewage well stopped in impurity depositing chamber. When the water level inside collector tank reaches the preset level for pump start, sewage pump will be started to discharge the water in tank and the impurities in depositing chamber together into outdoor manhole. When the water level inside collector tank reaches the preset level for pump stop, sewage pump will stop. Here, a cycle of sewage discharge is completed. Every time in the process of discharge, the impurities inside depositing chamber can be cleared once. This has avoided impurity deposit and regular manual cleaning. As impurity does not go through the sewage pump, so that there cannot be any damage to pump caused by clogging. This equipment has been greatly favored by both new and regular customers.

Features:

Outstanding discharge capacity and no clogging. The sewage doesn't go through the impeller of sewage pump and there cannot be any clogging in sewage pump. This can lengthen the service life of pump. Besides, the discharge diameter is not limited by the size of impeller passage, and the maximum diameter of sewage can reach the 80% of the diameter of discharge pipeline. Environmental protection and no pollution. As sewage is stored and discharged under enclosed state, there will be no overflowing and foul smell, and no pollution to the ambient environment. In domestic sewage discharge pipeline, one-way valve can effectively resist the backflow of foul smell. . Free from cleaning. Sewage and dirt are firstly separated and then discharged together through back flushing function. Every time the equipment runs, dirt will be discharged once. Meanwhile, water tank can be cleaned once by self-flushing function. This has really realized the effect to be free from deposit and cleaning, and has greatly reduced the labor and expenses of daily maintenance. . Improvement of utilization rate in constructions. Products are designed with compact structure, elegant profile, small occupation space for easy installation and less space, which has greatly reduced the expenses of operation and civil engineering. . Automatic control system. The system is provided full-automatic control, manual/automatic switchover, timed alternated operation of primary and auxiliary pumps, automatic startup on high and low water level, failure warning, etc., which is suitable for building automation design. In addition, man-machine interface can be provided upon request to carry out visualized remote regulation, monitoring and maintenance.

Q:What is the 10KV pump unit?
10KV should refer to the motor start voltage value, ultra high voltage start, the general pump more than 160KW of the motor, the voltage used in 6KV, you motor should be more than 300KW
Q:How should the water pump breaker be selected?
Schneider circuit breaker is not selected, I do not know how much current to drive the 11kw pump, and there is no other load?
Q:What is the defection of water pump
The structure of the water pump and water pump water.Because: when the pump head exceeds the rated head, pump current will increase, the water discharged from the pump impeller, back to the inlet of water from between the impeller and the casing exceeds the rated value, if it is a high lift pump, clearance between the impeller and the pump shell is very small, the current increases with increasing lift, current exceeds the rated value too soon many motor will be burned.
Q:Relationship between power and flow of sewage pump
If you simply want a formula that satisfies your everyday application, the following will meet the requirement:N= y QH/1000,The severe gamma liquid, cattle - ETA / m3; efficiency; N- kW; H- head, power meters;Q- volume flow per cubic meter / second; divided by 1000 is the change of power W to kW;Attachment: gravity is the density of an object multiplied by gravity. Acceleration is expressed as a force in terms of the weight of a unit;The formula is applicable to situations where the calculation is not high and applicable to any liquid known or known to be heavy;The formula is reduced to three simplifications:1, ignoring the pump impeller, shaft and other friction losses;2, ignore the pump flow loss;3, ignore the pump pipe, as well as mechanical heat loss;As a result of the above three loss in the process, material, liquid delivery the same condition can be simplified as a coefficient, then adjust the ETA - efficiency coefficient, can satisfy the application value.The deduction principle of this formula is relatively simple, and the mechanical work of the pump is considered to be transferred to the mechanical energy of the liquid completely;That is, N= gamma QH, at this time, all the mechanical energy that water possesses;Electrical and mechanical energy conversion efficiency exists, then divided by the conversion efficiency ETA is obtained;N= y QH/1000;Special attention is needed. - though the efficiency represents the input electric energy and water energy ratio; but the relationship between the two have many effects, the structure of pump, pump body, liquid material feeding. If the above formula is used to estimate, it should be revised according to the actual situation.
Q:What does water pump mean?
The pump is the pump, and pump the water where you want it
Q:Under what circumstances should we set up fire pool and fire pump room? Is it necessary to have a building?
Public construction property
Q:Should the no-load power of the pump be equal to the rated power?
Not equal to.1. Calculate the shaft power of centrifugal pump:Pa = HQ P /102 KWType H - pump rated lift, m;Q - rated flow of the pump, m3/s;P -- medium density, /m3 kg;Efficiency -- pump rated conditions (ETA = ETA ETA ETA m h V, m -- h -- mechanical efficiency, hydraulic efficiency,ETA V - volume efficiency);Pa - shaft power under rated working condition of pump, KW.2, determine the motor powerP=KPa/.Among them, P--- motors are equipped with powerShaft power under rated condition of Pa-- pumpETA - pump drive efficiency, general pump is using direct drive 1.K-- original motive power margin coefficient (shaft power less than 15KW, 1.25; 15 Pa > 55KW, 55KW > 1.15;, 1.1)
Q:30kW what is the flow rate of the pump?
Without a lift, how can I calculate it for you?
Q:22KW pump motor direct start circuit breaker and contactor size? Concrete calculation method
22KW the water pump motor is 380V. 22KW rated current is about 44A, 10 square copper wire is enough, the motor will often start off ah, if it is not available for DZ108-63 50A, CJX2-50 50A contactor is 380V.Pump motor (pump motor) according to the structure classification, should be divided into horizontal motor and vertical motor. Because of the work characteristics of pump starting torque is relatively small, the starting frequency is relatively small, relatively long time continuous operation and other characteristics, so the majority of pump motor asynchronous motor cage rotor or synchronous motor.The pump motor should be selected according to the selection of shaft power; motor shaft power power is greater than one level; for example: axle power is 15KW, select the motor should be: 18.5KW for motor with very few, according to the actual working conditions. 2 pole motor is generally used in the head of micro height, flow is not large (calculation is more complicated). Large flow, small lift occasions can choose 4 pole motor. Super large flow, lower head select 4 or 6 pole motor, when choose six pole motor, power can be reduced according to the shaft power of a grade.
Q:Intelligent pump controller, water is full water transfer automatically shows the next pool of water shortage, what is the matter?
The sensor is out of order or the line is out of contact.
