Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1-3, the technical solution provided by the present invention is: the utility model provides a zero shearing, super self-priming, high temperature resistance shell fragment sliding plate pump, includes rotor 1, stator 3 and sliding plate piece 2, in this embodiment eight and its divide into two sets ofly installed altogether to the sliding plate piece, and the same sliding plate piece of four block shapes of every group, its structure setting of installing first group draw-in groove and second group draw-in groove respectively. Each group of clamping grooves is provided with a group of sliding plate pieces conforming to the shape of the clamping grooves, the stator 3 is a pump shell, inlet pipes 31 and outlet pipes 32 are arranged on two sides of the pump shell 3 and are used for feeding liquid and discharging liquid respectively, the rotor 1 is provided with at least eight clamping grooves which are respectively a first group of clamping grooves 12 and a second group of clamping grooves 13, the first group of clamping grooves and the second group of clamping grooves are longitudinal grooves, the first group of clamping grooves 12 and the second group of clamping grooves 13 are provided with four clamping grooves, the shape state of the clamping grooves is shown in figure 1, and the sliding plate pieces 2 are arranged in the first group of clamping grooves 12 and the second group of clamping grooves 13 respectively. The built-in slide plate pieces of the four clamping grooves in the first group of clamping grooves are hard wear-resistant slide plates and move up and down along the stator of the pump shell during operation, and the built-in slide plate pieces of the four clamping grooves in the second group of clamping grooves are special elastic damping pieces fixed in a clamping mode; during operation, the four hard sliding plates in the first group of clamping grooves have the functions of conveying media and pressurizing; when the elastic damping sheet in the second group of clamping grooves runs between the inlet and the outlet, the elastic damping sheet is forcibly pressed into the Y-shaped groove on the outer circumference of the rotor by the stator to form local seal, and the whole volume chamber is divided into a vacuum suction area at the inlet pipe part and a high pressure output area at the outlet pipe part.

The inlet pipe 31 and the outlet pipe 32 in the present invention are provided with a protruded pipe opening 33.

The center of the rotor in the present invention is provided with a shaft hole 11 (as shown in fig. 3) for inserting the shaft.

Four of the first set of slots 12 are all rectangular structures.

The front ends of the second set of slots 13 are arc-shaped and are installed in cooperation with corresponding sliding plate pieces.

The working principle of the invention lies in that the change of the working volume formed between the pump cylinder and two adjacent blades on the rotor when the eccentric rotor rotates is used for conveying liquid or pressurizing the liquid. The rotor is a cylinder with radial slots, slide plates are arranged in the longitudinal slots (namely clamping slots), and the slide plates can freely slide in the longitudinal slots. The rotor is eccentrically arranged in the pump body, and when the rotor is driven by the prime motor to rotate, the sliding sheet is tightly pressed on the inner wall of the pump body by virtue of centrifugal force or spring force. In the first half rotation of the rotor, the space surrounded by two adjacent blades is gradually increased to form partial vacuum to suck liquid. Then, half a turn, the space is gradually reduced to press the liquid and to press the liquid into the discharge pipe.

The sliding vane pump has the advantages of compact structure, small overall dimension, uniform flow, stable operation, small pulsation and noise and higher efficiency than a common gear pump. The sliding vane pump has a complex structure and parts are easy to wear.

The slide plate pump of the invention also has the following remarkable characteristics:

1. the vacuum height is increased by about 25 percent compared with the vacuum height of the similar product.

2. The utilization rate of shaft power is high, the input power is low, and the output flow is high.

3. Long service life, few easily-damaged parts and simple maintenance.

4. Compact structure and convenient use.

The sliding plate pump has unique design, has the functions of idle running and forward and reverse running, can empty a pipeline by self-suction without filling and drainage, is compatible with the existing characteristics of volumetric pumps and centrifugal pumps, and breaks through the limitation that the idling is strictly forbidden or high-temperature gas and liquid mixed transportation cannot be realized in the prior art; the structure is simple, the manufacturing cost is low, the use cost is low, the maintenance is simple and convenient, the cost performance is high, and other similar products can be widely replaced in a plurality of processes.
