Dosing device. Dosing device is also known as dosing system and dosing equipment. It is mainly used for the treatment of water supply, furnace water, circulating water, waste water and other industries in power plants, and can also be used in petroleum, chemical, environmental protection, water supply systems and other industries.

The unit combined dosing device mainly includes solution tank, metering (1) and oilfield dosing device. It is mainly used for injection into wellheads and other systems on platforms in oil extraction.

What is a dosing device?

Dosing equipment .

Automatic dosing system Shanghai Sunshine Pump Industry is very reliable.

Automatic dosing system Structure and installation of automatic dosing system Structure and installation of automatic dosing system (automatic dosing device) Automatic dosing equipment uses sensing signals to control the working process of the dosing pump, and this control method requires monitoring instruments such as pH meter and conductivity meter and corresponding sensors. First, the control parameters (pH or conductivity) are set according to the operation needs of the system.

Dosing equipment .Dosing equipment product overview Automatic dosing equipment in electric power, petroleum, chemical industry, metallurgical industry, environmental engineering, dosing equipment is mainly composed of solution box, stirring box (with stirrer), metering pump, liquid level gauge, electric control cabinet, pipeline, dosing device according to the required concentration of chemicals, prepared in the stirring box, stirred evenly by the stirrer and put into the solution box, with a metering pump (dosing pump).

Progressive cavity pumps are positive displacement rotary lobe pumps, which rely on the volume change of the sealing cavity formed by the screw and bushing to suck in and discharge liquids.

The progressive cavity pump can convey lubricating oil, fuel oil, various oils and polymers, and is used to convey viscous liquids. Specific role, you can go to some manufacturers to see, there will be a more detailed introduction, it is recommended that you go to the official website of Shanghai Sunshine Pump Industry, there will be some technicians to solve the problem at any time.

This question shows that you don't know anything about progressive cavity pumps.

Screw pumps are widely used in food, textile, papermaking, Shishan Ming belt oil, chemical industry, shipbuilding, construction, nuclear engineering, Huai wax industry, metallurgy and mining, sewage treatment, etc.

How does a progressive cavity pump work and what is the principle? 1 minute 3D animation, intuitive and easy to understand.

There are mainly pumps composed of screws.

Startup Preparation 1Connect the suction hose 2Connect the outlet pipe 3

Check the oil level 4Check the fuel level5Check the air filter cartridge 6

Check the pre-filled water, and the pre-filled water should be topped up before starting2Initiation Action 1Turn on the fuel switch 2

Open the throttle to 1 2 at 3Close the choke 4Put the engine switch in the on position5

Gently pull up the start handle until there is a sense of resistance, and then pull quickly, pay attention not to hit the engine when putting the start handle back, and gently put back the anti-damage starter. 6.When the engine temperature rises, gradually open the choke 7

Set the throttle to the desired speed position.

Precautions for the use of progressive cavity pumps.

1. The parts of the screw pump should be carefully cleaned and inspected during assembly, and the damaged parts should be replaced;

2. When assembling the two universal joints of the transmission shaft, check whether the sealing ring is damaged and fill the cavity with grease;

3. The correctly installed bearing makes the shaft rotate flexibly and without jamming.

4. Shaft seal installation: when the stuffing box is installed, the packing gland hold-down bolt should be positioned in the housing installation window, so that the wrench can adjust the bolt;

5. When the discharge body is pressed and fixed, the nut should be tightened uniformly;

6. The mechanical seal should be installed carefully, and the end face of the friction pair should be cleaned and coated with grease;

7. When installing the stator, smear the rotor with lubricating oil, and the surface of the inner cavity of the stator is conducive to the installation of the stator;

8. When installing and assembling, the coupling installation deviation: y, 30.

Screw pump is one of the more common types of pump products, in many fields also have a wide range of applications, different kinds of pump products, its structure is not the same, have their own operating characteristics, screw pump is the same, the following will introduce to you the operation characteristics of screw pump.

The progressive cavity pump has strong variable conveying and self-priming ability, and also has the characteristics of reversibility and can transport liquids containing solid particles, so it is widely used in sewage treatment plants. There are at least two screw meshing screws of the screw pump, which can rotate in the shell to realize the suction and discharge of hydraulic pumps, and the screw pump is also a positive displacement pump that can use the screw rotation to make the studio change periodically.

There are many types of screw pumps, according to the number of screws, it can be divided into single screw pumps, twin screw pumps and triple screw pumps, etc., when the active screw rotates, the driven screw of its meshing will also rotate together, at this time, the screw meshing space volume at one end of the suction cavity will gradually increase, at the same time, the pressure will also decrease, under the action of pressure difference, the liquid will enter the meshing space volume, and then the liquid will move continuously along the axial direction in the sealing cavity in one seal chamber after another when the volume volume increases to form a sealing cavity, Up to one end of the discharge chamber, the liquid will be discharged as the volume of the screw meshing space at one end of the discharge chamber gradually decreases.
