Characteristics of vertical screw pump:

The special working cavity of the vertical screw pump can transport media containing suspended hard, soft solid particles and long fibers (or solid particles with multiple sharp edges and high wear), as well as media containing long fibers or entrained gases (liquid, solid, gas three-phase).

1. The size of solid particles is related to the eccentricity (e) of the "rotor" of each pump model.

2. The solid concentration can reach 40% by volume (such as 70% for powdered particles).

3. The fiber length is related to the lead of the "rotor" of each type of pump, allowing the longest fiber medium viscosity to reach up to 1000000 mpa. s (cp), which can effectively transport materials. This vertical screw pump has self suction characteristics: it can attract liquid medium through the pipeline and reach a height of 6-8.5 meters. The vertical screw pump product has unique performance, and the pump can also infinitely adjust the bursting (flushing) operation (supplementing or synthesizing various gases and sterilization gases into the medium) while infusion. By using a screw pump to transport and explode gas, various components in the medium are dissolved together.

The speed and flow rate of a vertical screw pump are linearly related, and the pump can have a fixed speed and flow rate. It can also be infinitely variable speed or multi-stage variable speed to meet the requirements of various characteristics of users, with flow accuracy (± 1%), and can be used as a metering pump for laboratories, drug dispensing, ingredients, etc.

The generation of pressure (head) is related to the spiral lead (T) of the "stator". One lead (T) outputs a pressure of 0.6 Mpa (60 meter head) in the differential pressure stage, while the two leads generate a second stage pump pressure of 1.2 Mpa (120 meter head).

According to the requirements of the working conditions, any type of pump can be manufactured, including vertical, inclined, and movable small vehicle mounted types.

The pump has few components and a simple structure, making it easy to disassemble and maintain. Even if it is used for the first time, it can be easily mastered in a short period of time.

The pump cannot operate dry without a medium and damage the hydraulic components of the pump because the "stator" is made of elastic material and the "rotor" is made of metal material. Performance of vertical screw pump:The flow rate ranges from 0.9 5 to 10 3 (m3/h).

The output pressure of conventional products is 0.6 Mpa (60 meter Yang Cheng).

Conventional temperature resistance>80 ° C, user specific requirements can reach 110 ° C

Based on the user's medium and physical properties, our company has developed a relatively complete material system for the selection of "stator, rotor, sheath" and overcurrent components after many years of research and development.

Shaft seal of screw pump: 1. Packing seal of various materials. 2. Single and double end face machine seals with various sealing materials for dynamic and static rings.

Our company can also design and supply supporting devices for users' special needs such as voltage stabilization or drainage.
