Introduction

Duplex filter

Double filter is also called double switch filter. It is composed of two stainless steel filters in parallel. It has many advantages such as novel and reasonable structure, good sealing performance, strong flow capacity, and easy operation. It can accurately ensure the filtration accuracy, and can quickly replace the filter bag, and filter basically no material. consumption, which reduces operating costs.

Application filtering hydraulic oil, lubricating oil, etc.; industrial quenching oil cooling system; RO security filtration, seawater desalination pretreatment, etc.
Filter media water suspended solids, particulate matter, water fouling, bacteria and algae, rust, etc.

Working principle

The double-cylinder switching filter is composed of two single-cylinder filters and a full-bore three-way ball valve. It has a simple structure and is easy to use, so as to ensure the safety of the system. During the working process, when the filter element of the single-cylinder filter is blocked to a certain extent and needs to be cleaned or replaced, the main engine should be stopped to replace the filter element. The disadvantage of the single-tube filter in this regard is that the filter element can be cleaned or replaced without stopping the machine to ensure the normal and continuous operation of the main engine. The characteristic of his work is that when one filter element is blocked and needs to be replaced, it is not necessary to stop the work of the main engine, as long as the three-way ball valve is switched to another filter, the other filter can participate in the work, and then replace the blocked filter. Filter element, the filter cartridge on the filter element side needs to be replaced, and a small amount of leakage is allowed.

Advantages

  • Double filter: Two three-way ball valves are used to assemble two single-cylinder filters on a machine base, and it is not necessary to stop the machine to clean the filter.

    Operate

    Easy installation:

    novel structure, easy and flexible operation, energy saving, high efficiency, closed work, stable operation

  • The double-cylinder switching filter is composed of two single-cylinder filters and a full-bore three-way ball valve. It has a simple structure and is easy to use.

    Structure

    Simple structure:

    The filter element/filter bag is supported by a metal mesh basket inside the filter. The liquid flows in from the inlet, and flows out from the outlet after being filtered by the filter element.

  • Choose good materials

    Material

    Using high-quality materials:

    The double-cylinder switching filter is composed of two single-cylinder filters and a full-bore three-way ball valve. It has a simple structure and is easy to use, so as to ensure the safety of the system.

  • Easy to use

    Convenient

    The equipment is easy to use:

    when one filter element is blocked and needs to be replaced, just switch the three-way ball valve to another filter, the other filter can participate in the work, and then replace the blocked filter element.
