1. WQ type submersible sewage pump, JYWQ jywq products are mobile installation and fixed installation of two basic forms. Can be designed according to the national standard drawing 01S305 "small submersible sewage pump selection and installation" selection. The hose connection to the mobile installation only submersible sewage pump motor power n is equal to or less than 7.5kW and exhaust pipe diameter DN is equal to or less than 100mm.
2. Submersible sewage pump with liquid level control device for automatic control. Float type liquid level control box is commonly used in liquid level control device. Installed in the sewage tank (sump) within the liquid level automatic control device should be far away from the water inlet.
3. Single submersible sewage pump weight greater than 80kg indoor sewage pool (wells) repair the hole at the top of the slab or beam should be pre embedded hook for installation and maintenance lifting submersible sewage pump, the chains bearing capacity must have a margin.
4. According to the provisions of the current "standard", in addition to the mobile installation hose connection points with a fabric reinforced rubber hose, submersible sewage pump discharge pipe can be the hard plastic water supply pipe, centrifugal casting nodular cast iron pipe, steel pipe. The bearing capacity of the pipe and pipe fittings shall not be less than 1.2MPa.
5. For building fire elevator set puddle of submersible sewage pump installation, should the two hard pipe is connected with a fixed or two fixed autotransformer type, and the effective volume of the puddle is not less than 2.0m3, submersible sewage pump rated flow not less than 36m³/h.
6. Tcontrol valve, check valve, flexible rubber pipe joint and pressure gauge should be set on the discharge pipe of the submersible sewage pump. National building standard design drawings 01S305 the small submersible sewage pump selection and installation of the "control valve gate valve are recommended for use, can also be in accordance with the needs of the butterfly valve; check valve is recommended to use spherical sewage check valve.
