According to the customer inquiry, a lot of customers want to purchase complete sets of products. The advantage of doing so is that for a single user, the procedure is simple and the connection is convenient, the workload can be effectively reduced, the post-maintenance is easy and the after-sale is easy to solve. Therefore, the selection of submersible pump products, in the following to do a simple explanation: Submersible pump complete sets of equipment includes five parts: First, the submersible motor and submersible pump pump parts are collectively known as the crew. This is the theme of complete sets of submersible pump equipment, under normal circumstances, there is no special customer conditions, submersible pumps are generally set at about 3 meters. Second, submersible cables Submersible cables generally occupy a larger part of the entire set of equipment costs. Because now copper prices have been rising, compared with 2008, it has nearly tripled. Select cable standard submersible motor power according to the size and distance of the transmission distance and voltage level to decide, generally divided into a single cable (which is three heart, that is usually said 3 by cable) Such cables are generally suitable for small Squared, cold water, close transmission. In hot water and high-power motors, a single cable * 3 is used for long-distance transmission, which is good for heat dissipation and easy operation. Third, Yang pipe General Yang pipe is divided into two types, when low-lift high-frequency welded pipe, which is what we usually say straight seam pipe or seam pipe. Generally use high-lift seamless fluid pipe, also known as seamless pipe. High-head submersible pump supporting the seamless fluid pipe buckle flange structure with buckle, high pressure, does not produce thorns phenomenon, when the higher head lift pipe and flange connection between the stiffener, better ensure that the lifting The safety and stability of use. Fourth, start the cabinet submersible pump start-up methods generally have three kinds: 1, since the lotus decompression start; 2, soft start; 3, variable frequency start. Since the lotus decompression start cabinet low price, simple operation, the corresponding start is not stable enough. Soft start affordable, start relatively stable, is now a complete set of equipment to choose more products. Variable frequency starter cabinet higher prices, but the start and its stable, energy saving, can change the motor speed, automatic water supply to achieve the purpose. Customers can choose according to their needs, the specific circumstances can consult the company related salesman. Fifth, the attachment Annex contains many, the definition of each manufacturer is not the same, my company is defined as: from the pump downhole until the wellhead outlet all the necessary small pieces. Including: covers, elbows, short tubes, pads, bolts, cable ties, wiring brass, waterproof tape, and so on. In summary, the selection of complete sets of equipment generally include these, of course, some special requirements also need to communicate with the company-related salesman and technical staff to better solve the problem for customers. Select the submersible pump must be based on the actual situation of the scene to choose, so selected pump can be durable.
