Types and structures of automatic dosing machines

Automatic dosing machines specifically include dual-pump single-control combination type, 3-pump dual-control switch combination type, combined type boiler water R value active control device, etc. There are some differences in the structure of each type, which are explained below.

1. Dual-pump single-control combination fully-automatic dosing facility. This facility consists of a metering calibration box, two dosing metering pumps (reserved for each other), a complete set of communication frequency conversion-type fully-automatic dosing control equipment, docking pipes, and gate valves. , base and other components. The capacity of the measurement calibration box is 1M' (customers have special requirements and will be discussed separately). Whether it can be equipped with a stirrer, remote transmission level gauge, liquid level height limit alarm and storage tank material selection is left to the customer or technician. The ministry pointed out that customers can also inquire directly from our company. Storage tank materials include steel, stainless steel, and rubber-lined storage tanks for different medicinal liquids. When ordering, customers must specify the following parameters of the dosing pump: Flow ( 1\/H), pump inlet and outlet load (MPa), pump flow path raw materials (or title and concentration value of transported drugs).

2.3 Pump double control switch combination fully automatic dosing equipment

The automatic dosing machine consists of 2 metering calibration boxes, 3 dosing metering pumps, 3 sets of AC variable frequency fully automatic dosing control equipment, docking pipes, gate valves, bases, etc.

Among the three dosing metering pumps of the fully automatic dosing equipment, pump 3 is the reserved pump for pump 1 and pump 2. Under normal circumstances, pump 1 and pump 2 are driven by two sets of communication frequency conversion type fully automatic dosing control equipment. The dosing metering pump can work in two ways, and the switch on the control cabinet can put the reserved pump into operation.

Customers can refer to the relevant explanations in the aforementioned dual-pump single-control combined fully automatic dosing facility for the standards for providing main parameters for metering calibration boxes, dosing metering pumps, etc.

3. Combined boiler water R value fully automatic dosing facility

The fully automatic dosing equipment is a fully automatic dosing facility used to coordinate phosphate treatment of boiler water (control the R value of boiler water). The fully automatic dosing equipment consists of 3 measuring and calibration boxes, 3 dosing pumps, and a complete set of communication frequency conversion The R-value active control equipment is composed of connecting pipes, gate valves, bases, etc.

The capacity of the three measurement and verification boxes is 1m³, which store sodium phosphate, sodium hydrogen phosphate and sodium hydroxide respectively.

Communication frequency conversion type R value active control equipment includes R value analyzer, automatic dosing control cabinet. Communication frequency conversion type automatic dosing machine control cabinet.
