Submersible borehole pump for 4 inch is mainly composed of the following characteristics: One type is a motor equipped with F insulation, high temperature, temperature, leakage and other sensor protection devices, which has high safety. In addition, the motor and pump adopt a structure. The pump seal adopts double mechanical seals. The mechanical seal directly in contact with water adopts tungsten carbide material. Then, the casting seal adopts tungsten carbide material, and the static seal adopts 0-ring seal, which has good sealing performance. , The pump can be directly submerged into the water, with good cooling performance and space saving. Then, the cable uses heavy-duty rubber flexible cable, which has good mechanical strength and pollution. The cable and the cable pressure plate are sealed with a sealing ring, which is very reliable.

Submersible borehole pump for 4 inch is installed in three stages:
Generally speaking, the installation of Submersible borehole pump for 4 inch is divided into three stages: preparation before installation, installation on the oil well, and installation of the axial flow pump. Let's briefly introduce these three stages.
First, prepare for installation of Submersible borehole pump for 4 inch:
The pre-installation preparation work is mainly to check and measure the submersible axial flow pump and the predetermined installation position of the construction site. Determine the installation coordinates and oil well pivot baseline by measuring the installation position and drainage line of the submersible axial flow pump. However, the Submersible borehole pump for 4 inch itself needs to be checked for various parts.
The next thing I want to introduce is the installation on the oil well.
It is necessary to install the oil well fixing bracket, but before that, determine the reference point of the equipment outlet, and install the oil well fixing bracket according to the reference point. Then there is the operation of the oil well hoisting position. In this process, it needs to be completed manually in cooperation with the crane. Please note that it is easy to collide with other objects in long oil wells, so be careful during the hoisting process. It can also work normally after reaching the oil well hoisting position. After reaching the lifting position of the oil well, fix and correct the oil well.
After all the above work is completed, the axial flow pump should be installed. Hang the axial flow pump on the wellhead. This work is also done manually with the crane. Then, along the oil well, slowly drip the axial flow pump onto the support at the bottom of the oil well, correct it, tighten the bolts, and fix it.
These are the three stages in the installation of Submersible borehole pump for 4 inch. It doesn’t look too complicated, but there are many things to pay attention to in actual work. Each stage has to bear this stage, so there can be no mistakes in each stage. The combination of care and technology.
