WQ series submersible sewage pump is digesting and absorbing foreign advanced technology developed on the basis of success, a team with efficiency and prevent winding, no jam, automatic coupling, the advantages of high reliability and automatic control, solid particles and long fiber waste in lining, has the unique function.
This series of pump discharge water diameter of 50 ∽ 600 mm, flow 10 to 7000 m3 / h, head of 5 ∽ 60 m, 1.5 ~ 315 kw power, through the solid particle diameter of 20 ~ 145 mm.
Uses and features
WQ series submersible sewage pump is mainly used in municipal engineering, industrial, hospitals, buildings, hotels, restaurants and other industries. Used for lining with solid and all kinds of long fiber sludge, waste water, urban sewage (including the occasion of corrosive and erosive medium).
WQ series submersible sewage pump is small in size, compact structure, high efficiency, can according to user requirements for water level automatic control, and equipped with automatic protection device and the control cabinet, double guide rail automatic installation system, etc.
Conditions of use
1, motor rated voltage 380 v, 50 hz frequency three-phase ac power supply.
2, medium temperature does not exceed 40 oc.
3, conveying liquid medium PH value of 4 to 10.
4, transmission medium solid phase volume ratio under 2%.
5, medium density is less than 1.2 x 103 kg/m3
Structural characteristics of
WQ series submersible sewage pump compact structure, and set the various states, according to a protection device, the pump running safety and reliable.
1, the unique design of cable seal ruled out the cable leakage hidden trouble.
2, stator with F class insulation, equipped with thermal protection components.
More than 3, 18.5 KW pump adopts automatic circulating water cooling, to ensure the safe operation of the pumps in the lowest level state.
4, float switch installed at the bottom of the motor chamber under, implement guardianship for motor mechanical seal.
5, of the oil pump and motor chamber top with oil-water probe, implement guardianship for lateral pump mechanical seal, once leakage, control system will alarm protection.
6, bellows type double mechanical seal, the sealing material for tungsten carbide, silicon carbide and tungsten carbide, prevent water from entering the motor and ensuring safe and reliable operation of the motor.
7, vice impeller mechanical seal is used to balance the external pressure, prevent water into the oil chamber, so as to prolong the service life of electric pump.
8, impeller and unique design, big flow to through the long fiber and dirt, anti-clogging, winding, flow ability.
9, impeller and volute fitted with replaceable wear set between the bottom, keep the pump run at optimal efficiency.
The impeller design characteristics
In order to guarantee the smooth of the sewage through, must strengthen the impeller flow surface width, for large pump, can use double blade, three-blade; For a small pump, in the form of single (double) port, it is similar to a cross section bend with the same size, and very good flow characteristics. To avoid the water flow under the condition of low speed may cause jams, coil. This unique design of impeller passage with reasonable volute chamber, make wastewater in paper, textiles, bags and other materials can free pass. Impeller after dynamic and static balance, make the pump in the no-load test run and vibration are not produced in the process of loading.
Install and use
This company produces the diving sewage pump, pump and coaxial, compact structure, high efficiency, easy installation and maintenance, economic operation, strong adaptability, its installation method are mobile and fixed installation, fixed installation is divided into automatic coupling installation with fixed dry installed, installed mobile also called freestyle.
