if you find that the sewage pump has abnormal sound, you should stop immediately to check the cause PE gas pipe. When the sewage pump wants to stop using, first turn off the gate valve pressure gauge and then stop the motor. Within the first month of operation, the sewage pump will change the lubricating oil every hour after hours, Change the oil once, often adjust the packing gland to ensure that the dripping and leakage in the packing room is normal (it is appropriate to leak in drops), and regularly check the wear of the shaft sleeve. After the wear is large, replace the sewage pump in time. When it is used in cold winter, after stopping, unscrew the drain plug at the lower part of the pump body to drain the media to prevent frost cracking

a submersible sewage pump adopts an automatic liquid level control device for automatic control. In addition to the floating ball liquid level switch, if the sewage contains no or only a small amount of suspended impurities, the input pressure sensor and supporting secondary instruments can also be selected. The automatic liquid level control device installed in the sewage pool (sump) should be as far away from the water inlet as possible, 2. The weight of a single submersible sewage pump is greater than kg. 1. Strengthen standards and regulations. The building above the manhole of the sewage pool (sump) in the studio is also concentrated in the aspect of engineering strength. The hook should be embedded on the plate or beam for lifting the submersible sewage pump during installation and maintenance. 3. According to the provisions of the current relevant specifications, Except that the connection part of the movable installation hose adopts fabric reinforced rubber hose, the discharge pipe of the submersible sewage pump can adopt hard water supply plastic pipe, centrifugal casting ductile iron water supply pipe, steel pipe, steel plastic composite pipe, etc., and the pressure bearing capacity of the pipe and pipe fittings should not be less than MPa. IV. the installation method of the submersible sewage pump used in the sump of the fire elevator of the building should adopt two hard pipe connection fixed type or two fixed self coupling type, and the effective volume of the sump should not be less than m, The rated flow of submersible sewage pump shall not be less than m/h

v. control valves, check valves, flexible rubber pipe joints and pressure gauges should be set on the discharge pipeline of the submersible sewage pump. Gate valves are recommended for the control valves in the national building standard design atlas s "selection and installation of small submersible sewage pumps". In order to ensure the construction quality of the secondary circuit wiring installation project with digital display and microcomputer control, and promote the improvement of the engineering construction technology level, To ensure the safe operation of panel and cabinet devices and secondary circuits, this specification is formulated. This specification is applicable to the construction and acceptance of the circuit wiring installation works of all kinds of distribution boards, protection panels, control panels, cabinets and complete sets of cabinets, as well as the secondary Jinan servo control cabinet suppliers. The installation works of panel and cabinet devices and secondary circuit wiring should be constructed according to the approved design, When handling and installing panels and cabinets, safety measures such as shockproof and moisture-proof measures should be taken to prevent frame deformation and paint damage. If necessary, the installation equipment and vulnerable components can be removed and packaged separately for transportation. When the product has special requirements, it should also comply with the provisions of the product technical documents. The panels and cabinets should be stored indoors or in a dry place that can be protected from rain, snow and sand. The installation equipment and electrical components with special storage requirements should be kept according to the provisions

the equipment and apparatus used must be qualified products that meet the current national technical standards and have qualification certificates. The equipment should have nameplates. After arriving at the site, the equipment and apparatus should be subject to acceptance inspection within the specified period, and should meet the following requirements: first, the packaging and sealing should be good; second, the unpacking inspection model and specification should meet the design requirements, the equipment should be free of damage, the accessories and spare parts are complete; third, the technical documents of the products are complete; fourth, the appearance inspection should be qualified according to the requirements of this specification, The safety technical measures during construction shall comply with the provisions of this specification and the current relevant national safety technical standards and product technical documents. The construction of construction works related to the installation of panel and cabinet devices and secondary circuit wiring shall meet the following requirements: the construction quality of building structures related to the installation of panel and cabinet devices and secondary circuit wiring

it shall comply with the relevant provisions of the current national construction and acceptance specifications. When there are special requirements for the equipment or design, it shall also meet the requirements. 2. Before the installation of the equipment, the construction project shall meet the following conditions: the construction of the roof and floor slab is completed, and no leakage is allowed; Finish the indoor ground work, and there is no ponding and sundries in the indoor ditch; The embedded parts and reserved holes shall meet the design requirements, and the embedded parts shall be firm; Jinan automation engineering manufacturer has completed the installation of doors and windows; When carrying out decoration work, the decoration work that may damage the installed equipment or cannot be carried out after the installation of the equipment is completed. For three pairs of equipment with special requirements, the construction works should meet the following conditions before installation and commissioning: all decoration work is completed and cleaned; If special facilities such as air conditioning or ventilation devices are installed, they should be installed and put into operation. After the construction of secondary circuit wiring, the Jinan automatic control cabinet supplier should have safety technical measures to prevent the damage of weak current equipment when testing the insulation. After the installation and commissioning of the control cabinet
