Description

[0001] The present invention relates to an oil filter for a pump,

The present invention is intended to purify impurities of a fluid directly connected to one side (for example, an upper end) of various pumps including an industrial pump, and at the same time to make a relief valve and a pump always check pump discharge pressure. The relief valve and the vacuum gauge which are externally coupled to the filter body are formed so as to be easily disassembled and assembled so that they can be exchanged and replaced for each part And an oil filter having a direct-coupled pump structure, characterized in that it is excellent in cost reduction due to individual handling of the consumable material during maintenance and secures a convenient and safe workability for an operator.

Fluids typically flow from high to low, but sometimes they need to be transported from low to high and sometimes to high pressure. In this case, it is impossible without supplying energy to the fluid. Therefore, the electric motor converts the energy possessed by the fluid into mechanical energy or converts the mechanical energy into the fluid energy using the fluid (liquid, gas) as the working material, To energize electrical energy to mechanical energy and mechanical energy to the fluid to transfer the fluid to a higher position.

If the fluid machine is classified by the working fluid, it can be classified as a hydraulic machine and an air machine. As a representative model of a hydraulic machine, one type of fluid machine is a pump.

These pumps started to be used in shipbuilding, water supply, drainage, drainage, agricultural irrigation, industrial use, power generation, and various industrial applications .

Industrial pumps are widely used in chemical plants and industrial machinery, as well as heavy chemical industries and agriculture.

Industrial pumps are classified into turbo type, volumetric type, and special type according to their operating principles. The turbo type is a type that directly controls the flow with an impeller, and the way in which energy is transferred by the volume change while the fluid is completely trapped in the chamber or the flow path is called the volumetric type.

The pump type is called the special type, and the pump whose operation principle does not belong to the turbo type or the volumetric type.

Depending on the geometry of the flow path, the turbo pump can be divided into centrifugal, multistage, and axial flow types. Centrifugal and multistage pumps are structurally divided into a vortex pump with a guide collar and a diffuser pump without a vane collet. They are also divided into a single-stage pump and a multi-stage pump according to the number of stages, and the single-stage pump and the multi-stage pump are classified into one suction type and two suction types according to the suction type.

It is desirable that the pumps used for industrial use have the functions required for each application and have a kind of pump and a system for operating it in consideration of safety and economical efficiency.

In order to remove impurities in the fluid, these pumps are adapted to receive the filter member in the oil tank to remove the impurities when the pump is inhaled. Such a filter combining structure may be replaced or replaced by the failure or wear of the filter member It is necessary to carry out replacement and replacement work in the tank, which is a difficult and troublesome task, and in particular, there is a risk that the worker is at risk of safety.
