TJP sewage lifting equipment I. Introduction "underground toilet sewage lifting equipment integration" is the Pan-green shares independently developed specifically for underground sewage lifting toilet intelligent products, with 52 national patents. On the design ideas revolutionized the traditional way of promotion, the "solid-liquid separation," "backwash", "integration", "intelligent" and so the concept of the perfect combination of intelligent design a series of sewage lifting equipment. "Solid-liquid separation" is the sewage completely separated from the debris and sewage, sewage impellers never come into contact with its killer: wrapping material, hard, to ensure the normal use of the environment of the pump, greatly extend its life, maintenance rate is very low; "backwash" is the use of pump pressure, through a precise calculation of the hydraulic model and will remain in the solid-liquid separation discouraged debris recoil, elevated to the municipal pipe network, as well as a stream of water at the pump pressure backwash bottom of the tank, so that sewage sludge may no hiding place, was promoted to the outdoors with the water pipe network; "integration" is the device as a whole integrated structure, no new cesspools, small footprint, low investment; "intelligent" means it is fully automated operation, without human care and operation of the fault also has an automatic alarm function. Second, the principle introduced integrated intelligent underground toilet sewage lifting equipment are tanks, lift pump, auxiliary drain pump, control cabinet and the corresponding solid-liquid separation equipment, water distribution, valves and other components. Third, the device components to enhance the pump 1. Introduction: When the lift pump designed for built-in, the use of submersible sewage pump; when the external design, the use of vertical sewage pump dry. 2. Case: 304 stainless steel, bottom and side panels 2mm thick, the upper box to open an exhaust pipe connected to the use of the best outdoor or drainage connection with the building ventilation system; the bottom of the box opened outfall, diameter of DN25, 304 stainless steel ball valve manual control, easy maintenance and inspection when emptying sewage; relying on the top side of the box open with three pumps, cable outlet hole gauge, and the hole is equipped for easy threading of the line card; box can withstand a maximum pressure generated by the corresponding amount of sewage treatment, corrosion-resistant. 3. The solid-liquid separation device: 304 stainless steel, built-separator tube, bottom with reinforcement. The backwash means: 1) solid-liquid separation apparatus backwash: 304 stainless steel, connected to the bottom of the solid-liquid separator, connection angle <5 °; 2) means backwash tank: 304 stainless steel, mounted on the solid-liquid separating apparatus and an upper side portion, when the high pressure water pump start flushing tank bottom. 5. triple safety device: 304 stainless steel, plays the role of water diversion, sewage reflux device under special circumstances. Wall smooth, no glitches phenomenon, equipped with top water inlet filter, equipped with ventilation tube reflux device. 6. Valve: 304 stainless steel, DN100-SN150, pressure range: 0.6-1.0Mpa, valve manufacturing, connection and operation of compliance with the relevant national standards. 7. pipes and water distribution: 304 stainless steel, wall thickness 2mm, DN25-DN150. Fourth, the device model illustrated example: TJP (S) -15-20-2.2 / 2 (W) TJP: Pan brand sewage lifting equipment integration (S): None: Standard S: villa special type T: a special type 15: Nominal flow (m3 / h) 20: Equipment upgrading lift (m) 2.2: single pump power (KW) 2: number of pump units (W): None: Pump Built-in; W: Pumps External five, equipment selection Points 1, built-in dual-pump (TJP): suitable for underground shopping malls, supermarkets, hotels, subway stations, and other public health * places, equipment installed in the same layer or a layer of toilet facilities pit floor. Pit installation need to configure an auxiliary pump for discharge device seepage pits, stormwater runoff and other auxiliary pump is generally used in the float comes sewage pumps, installed in a small sump sump, recommended size is 500 * 500 * 500mm, auxiliary pump outlet connected directly to the equipment, the total outlet. 2, built-in dual pump (TJPT): suitable for bathroom drainage flow smaller venues (such as: high-end clubs, shopping malls, supermarkets and other staff toilet, does not apply to inter-medium-sized public health). Equipment is typically installed on the same device layer toilet pit. Pit installation need to configure an auxiliary pump. 3, double-pump external TJP (W): equipment installed on the ground floor under the toilet. General unworthy auxiliary pump (non-installed in the pit). 4, a single pump built-in (TJPS): only applies to a single bathroom (a toilet, a wash basin) place (villa private clubs, etc.). Equipment is generally installed in the same layer device pit, need to reprovision one auxiliary pump. 5, Villa double pump (TJPS): only applies to luxury villas, private bathroom with floor drain underground clubs. Equipment is usually installed in the pit equipment, need to reprovision an auxiliary pump; double pumps run alternately, more secure and reliable. Six, select 1. Single pump capacity built-in: the capacity should be considered one of the main pump power plus an auxiliary pump power; 2. Built-in dual pump: electric capacity should consider two main pump power plus an auxiliary pump power ; 3. Dual pump External: Power capacity should consider two main pump power; 4. Villa Two pumps: electric capacity should consider two main pump power plus an auxiliary pump power. Seven, installation technical notes TJP: 1. equipment using pit installation, the default shall be reserved for the pit. Reserve pit dimensions see installation size table, requiring pit area flat; 2. equipment in place, the application of low-end foundation anchor bolts are fixed; 3. equipment outlet valve should be installed so that the device routine maintenance and repair; 4. The device should be connected to the outdoor vent pipe connected to the building drain or ventilation systems; 5. reserve pit installation convenience requirements of the upper lid open, easy maintenance, overhaul, open manhole cover breather after half an hour, before its operation; 6. The pit should have a 500 * 500 * 500mm drainage pit, install auxiliary pump for maintenance of equipment; 7. Other outstanding issues, please refer to the corresponding specifications civil, structural, equipment installation. TJP (W) series of ground-mounted installation requirements schematic Technical note: 1. External sewage lifting equipment can only be used on the ground-mounted (non-pit installation), the requirements remain flat ground; 2. equipment in place, the basis of the requirements of the land base of the foot bolts fixed; 3. equipment outlet valve must be installed in order to equipment maintenance and repair; 4. snorkel equipment should be connected to the outdoors or connected with the building ventilation and drainage systems; 5. gutter next to the device shall be provided for easy maintenance drainage and emergency drainage; 6. Other aspects of regulatory requirements, refer to the appropriate civil engineering, construction, equipment installation. TJPS / TJPT series pit installation diagram Installation Requirements Technical note: 1. equipment used during the ground-mounted, require ground remain flat; 2. equipment in place, the base foundation with anchor bolts are fixed; 3. The equipment must be installed on the outlet valve, so that the device commissioning and maintenance; 4. snorkel equipment should be connected to or connected with the building outdoor ventilation and drainage systems; 5. Equipment shall be provided next to the gutter, drainage and ease of maintenance of emergency drainage; 6. equipment used pit When installed, the need to pre-reserve pits.
