[Asia Pump Network News] Submersible sewage pump is a pump and motor Siamese, and at the same time dive into the work of the sub-pump products. It plays a very important role in various industries such as municipal engineering, industry, hospital, building, restaurant, water conservancy construction, etc. Therefore, it is highly favored and loved by consumers. However, due to the lack of consumers in the purchasing process due to the lack of relevant technical knowledge and guidance of professionals, often know what is wrong, and the purchase is not satisfied with the appropriate submersible sewage pump. So understand the submersible sewage pump option is particularly important. Impact of submersible sewage pump selection four major factors 1, head: vertical height, horizontal distance, elbow and other factors will affect the submersible sewage pump head. Under normal circumstances, the selected submersible non-clogging sewage pump should be less than 20% of the required lift; lower than the required head would not hit the water, higher than the rated lift will make the submersible pump exceeds the rated flow access, the motor will appear Overcurrent caused by the heat or even burn the machine accident. 2, flow: submersible sewage pump selection is to take into account the occurrence of heavy rainfall, typhoons and other weather, will give waterlogging and other business conditions, the design of the flow must ensure that special circumstances occur, the general requirements of the main pump and auxiliary pump. 3, the size and mode: WQ type submersible sewage pump plus elbow size is generally larger, to take full account of the size of the sump, if too small will cause heat is not timely and so on, there are two submersible pump installation The way that the mobile installation and the coupling installation, in which the mobile installation is relatively simple, just pull the pump with rope hanging into the sewage pool, the coupling installation is more complex, under the guidance of manufacturers, of which auxiliary devices: Gourd, stainless steel chains, rails, etc. must be equipped. 4, the power supply voltage: three-phase power supply motor voltage is 380V; single-phase power supply motor voltage is 220V. Commonly used civilian electricity 220V single-phase sewage pump, industrial enterprises generally choose 380V three-phase sewage submersible pumps, mining enterprises generally choose 660V / 1140V explosion-proof type. Above is the submersible sewage pump purchase some of the basic methods, I hope your purchase to provide some help. This article belongs to Industrial Internet (Xiamen) Technology Co., Ltd.

Bolt
Stainless steel bolts are divided into hex bolts, hex flange bolts, hex socket bolts, U bolts, weld Stud bolts, wing bolts, carriage bolts, Eye Bolts and so on.
A stainless steel bolt fastener is a type of mechanical fastening device made from stainless steel material. It is designed to secure two or more objects together by applying torque or tension. Here are some ways to describe a stainless steel bolt fastener:
1. Material: The fastener is made from high-quality stainless steel, which provides excellent corrosion resistance and durability.
2. Shape: It typically has a cylindrical body with a threaded shaft and a head at one end.
3. Size: The size of the bolt can vary, ranging from small to large, depending on the application requirements.
4. Thread: The bolt features a threaded shaft, allowing it to be screwed into a corresponding threaded hole or Nut.
5. Head: The bolt's head is usually hexagonal or square-shaped, providing a gripping surface for a wrench or socket to tighten or loosen the bolt.
6. Strength: Stainless steel fasteners are known for their high tensile strength, ensuring a secure and reliable connection.
7. Finish: The bolt may have a polished or brushed finish, giving it a sleek and aesthetic appearance.
8. Versatility: Stainless steel bolt fasteners are widely used in various industries, including construction, automotive, and manufacturing, due to their resistance to corrosion and ability to withstand harsh environments.
9. Longevity: Due to their stainless steel composition, these fasteners have a longer lifespan compared to other materials, making them ideal for applications that require durability and longevity.
Remember to provide specific details about the bolt's dimensions, such as length, diameter, and thread size, if necessary, to accurately describe the fastener.
