Description
Technical Field
The utility model relates to a immersion multistage centrifugal pump's field, concretely relates to modified CDLK immersion multistage centrifugal pump body structure of intaking.
Background
In recent years, with the rapid development of economic construction and the acceleration of urbanization process in China, equipment is manufactured more and more, machine tool equipment is brought more and more, the requirement of a special pump for a machine tool is indirectly driven, and the CDLK of our department is a special pump specially provided for the machine tool equipment and mainly used for circularly conveying cutting fluid of the machine tool. The quality of the performance of the machine tool directly influences the machining quality of the machine tool. At present, manufacturers such as grand Fuji and the like in the market have related products for sale, and similar technical schemes are adopted.
However, after the existing product is used by a customer, part of the customers feed back that the filter screen at the inlet of the existing CDLK immersion type multistage centrifugal pump is easy to block in the process of conveying cutting fluid, so that the customers need to frequently clean the filter screen, and the maintenance time and cost are increased.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to overcome the not enough of prior art existence, and provide a modified CDLK immersion multistage centrifugal pump body structure of intaking, have simple structure, convenient to use, safe and reliable's advantage.
The purpose of the utility model is accomplished through following technical scheme: the improved water inlet body structure of the CDLK immersion type multistage centrifugal pump comprises a water inlet body shell, a filter screen, a base, a screen mesh, a pressing plate and screws, wherein a plurality of connecting lugs are uniformly distributed on the outer wall of the water inlet body shell and are used for being fixedly arranged at a water inlet of a pump body in a matching manner with connecting bolts; the lower part of the water inlet body shell is inwards sunken to form a groove, and the base is sleeved on the groove, so that the water inlet body shell and the base are detachably connected and fixed; the lower surface of the base is provided with a bottom water inlet, and the silk screen is fixedly arranged on the bottom water inlet through a pressing plate and a screw, so that bottom filtration is realized; evenly set up a plurality of side inlet openings along the base lateral wall, the filter screen is embedded to be installed at the inner wall of base to with each side inlet opening laminating, realize side and filter.
As a further technical scheme, a plurality of protruding points are uniformly distributed along the inner wall of the top of the base and used for being matched with the grooves to fix and position the base.
The utility model has the advantages that:
1. the structure is simpler and more convenient, the operation is simple and convenient, and the installation and the maintenance are convenient;
2. the water inlet hole surface is increased, so that the phenomenon that the filter screen is completely blocked can be effectively solved, and the efficient and stable operation of the water pump is realized;
3. split type design, in the pump assembling process, do not assemble the base in advance, intake body assembly test accomplishes the back, uses the paper of sealing to seal inside residual water, avoids liquid outflow to the wrapping bag lead to the rust problem of pump body surface, and the base assembles at the customer scene.
