Problems solved by technology

As a result, so far, the enterprises that produce water filter pipes have not implemented the national standard on the opening ratio, and most of them are only half of the national standard of 15%, that is, 7-8%, which greatly affects the water output of the motorized well and its service life.

Embodiment Construction

[0020] The well pipe mold of the present invention is controlled by a speed-regulating motor to rotate, and the rotation speed of the well pipe mold is adjusted by the motor, which is a prior art. The well pipe mold is an existing two-half mold mold.

[0021] The manufacturing method of the well pipe of the present invention comprises two kinds, and a kind of well pipe that is used to make the well pipe that does not perforate on the pipe wall such as the well wall pipe, the method steps are as follows:

[0022] (1) Start the motor, the well pipe mold starts to rotate, control the speed at 130-180 rpm, put the concrete mixture into the well pipe mold evenly through the openings at both ends of the well pipe mold, and as the well pipe mold rotates, The concrete mixture will evenly stick to the inner wall of the mold under the action of centrifugal force, and stop feeding when the required wall thickness is reached. The wall thickness varies according to the specifications of t...

Abstract

The invention discloses a method for manufacturing a well casing. The method comprises that: a concrete mixture is evenly put into or poured into a rotary well casing mould through openings at two ends of the well casing mould; and an iron roll is put into a port of the rotary well casing mould to roll the concrete mixture in the well casing mould repeatedly, and the concrete mixture is compacted. The method for manufacturing the well casing has the advantages of simple operation, high concrete strength, little damage to a body of the well casing, and high integrated intensity of the manufactured well casing.

Description

technical field [0001] The invention belongs to the technical field of well pipes, in particular to a method for making well pipes. Background technique [0002] The forming process of the well pipe is mainly produced by the centrifugal method, and a small amount is produced by the suspension roller method. Centrifugal method is divided into double-opening centrifugal steaming method and whole-mold spraying wax centrifugal molding method. The double-opening centrifugal method is made of two halves. The mold has been in production for a long time, and the wear is serious. The joints are prone to grout leakage. The centrifugation time is long, and the separation of stones, sand, and cement grout is easy to occur. The inner wall has serious laitance and the concrete strength is low. Whole mold wax spraying centrifugal molding method is conducive to mechanization of production, but the outer diameter is not easy to control, and the operation technology requirements are relative...
