WQ type non-blocking submersible sewage pump is based on the introduction of foreign advanced technology in our factory, and the joint efforts of scientific research personnel, while seeking the opinions of domestic water pump experts, and repeated improvements and tested performance indicators have reached similar foreign products Advanced level. This product has features such as a simple and unique structure with high efficiency and energy saving. After the product is put on the market, it is welcomed and praised by customers with its unique design and reliable quality. Selected by many units as a substitute for imported products.
GW 型堵塞管道排污泵、 WL 型立式排污泵三大系列是我厂在 WQ 潜水式排污泵的基础上，根据用户的要求及使用条件，方式不同，进行合理设计而成的，其水力模型同 WQ 型泵。 WY type non-blocking submersible sewage pump, GW type clogged pipeline sewage pump, WL type vertical sewage pump are three series of our factory based on WQ submersible sewage pump, according to user requirements and use conditions, different methods, Reasonably designed, its hydraulic model is the same as WQ pump. After the product is put on the market, it is welcomed and praised by customers with its unique design and reliable quality.
Conditions of Use:
40 ℃） PH 值在 4-10 之间。 The electric pump conveys the medium temperature slurry (less than 40 ℃). The PH value is between 4-10 . 2 ％以下。 The volume ratio of the solid phase of the transport medium is less than 2 %.
The head of the submersible pump should not be too low. 80 ％容易引起热保护器工作。 Below the stipulated head 80 %, it is easy to cause the thermal protector to work. Stop the electric pump and even cause damage to the motor.
Structural characteristics and working principle:
This series of electric pump consists of three parts: water pump, seal and electric instructions. The electric instructions are located on the upper part of the pump and are single-phase or three-phase asynchronous electric instructions. The water pump is located below the electric pump. It is a runner-type impeller and volute structure. O 型耐油橡胶密封圈作静密封。 A mechanical seal is used between the water pump and the electric instructions, and each fixed non-return seal uses an O -type oil-resistant rubber seal for static sealing. Ensure the reliability of the electric pump.
The electric pump rotor shaft is made of stainless steel. Ensuring more reliable mechanical strength of the shaft can effectively improve the wear resistance and corrosion resistance of the shaft. It is also easy to repair and disassemble the impeller.
This series of electric pumps are widely used in industrial, agricultural, mining, building construction, municipal environmental protection and other places. Pumps liquids containing solid particles such as short fibers, paper scraps, sand, or software solids. Such as mud water, grey water, domestic wastewater, sewage, dung, etc., it is an ideal water conservancy equipment for agricultural drainage and irrigation, river pond dredging and construction site construction, but it is not suitable for occasions with explosion-proof requirements.
Some specifications use runner impellers. The anti-clogging ability of the pump is greatly improved; some specifications adopt the full head theoretical design so that the electric pump can maintain no overload operation under normal conditions, effectively extending the electric service life.
The introduction of cutting series electric pumps has digested and absorbed foreign advanced technology and carried out novel and unique designs using the shear principle. Long fibers, plastic paper bags, etc. can be cut or torn to keep the pump's flow path unobstructed.
