SH(R)/SM(R)/SL(R)/SHH(R) Series Slurry Pumps

SH(R)/SM(R)/SL(R)/SHH(R) series mud pump is a horizontal heavy-duty slurry pump. The horizontal slurry pump is a suspended wall centrifugal slurry pump, which is suitable for conveying abrasive or corrosive slurry. It is widely used in metallurgy, mining, petroleum, chemical industry, coal, electric power, transportation, river dredging, building materials and municipal engineering departments. Its structural characteristics, according to the scope of use can be divided into heavy-duty slurry pump, light-duty slurry pump, gravel pump and lining rubber pump, horizontal slurry pump is designed to deal with high abrasive, high density mud, with excellent wear life, while maintaining efficiency in the wear cycle, providing a suitable total operating cost.

Product Introduction

The horizontal slurry pump is a suspended wall centrifugal slurry pump, which is suitable for conveying abrasive or corrosive slurry. It is widely used in metallurgy, mining, petroleum, chemical industry, coal, electric power, transportation, river dredging, building materials and municipal engineering departments. Its structural characteristics, according to the scope of use can be divided into the following forms:

1. Heavy-duty slurry pump has thicker bearing parts and is equipped with heavy-duty brackets, so it is suitable for conveying strong abrasion, high-concentration slurry or low-concentration high-lift slurry. Within the maximum allowable working pressure range of the pump, it can be used in multi-stage series. The above type of pump can also be used for a certain corrosive slurry.

2. The light-duty slurry pump has high speed, small size and light weight, and is suitable for conveying fine particles, low-concentration slurry or corrosive slurry. The weight concentration of the conveying slurry is generally not more than 30%, and it can also be used to convey high concentration and low abrasive slurry.

3. The gravel pump has a large flow passage, which is suitable for conveying gravel, mud and slurry with large solid particles.

4. The flowing parts of the rubber lining pump are made of rubber material. Its pump body, pump cover and transmission parts are common to heavy-duty slurry pumps and light-duty slurry pumps. Suitable for conveying fine particles and corrosive slurry.

Structure Description

The above various types of horizontal slurry pump in addition to the pump head part (including pump body, pump cover, impeller, etc.) structure is different, the rest of the structure is similar, using the same series of transmission parts. Below according to the pump head part, shaft seal part and transmission part, respectively, describes its structural characteristics.

1. Pump head part

Heavy-duty slurry pump and light-duty slurry pump are of double-shell structure, I .e. the pump body and pump cover are provided with replaceable wear-resistant metal lining (including impeller, sheath, guard plate, etc.). The pump body and cover are made of gray cast iron or ductile iron according to the working pressure, and are connected by bolts in the vertical opening. The pump body has a stop and is connected with the bracket by bolts. The discharge outlet of the pump can be installed in eight angles of rotation. The front and rear cover plates of the impeller are equipped with back blades to reduce leakage and improve the service life of the pump.
The rubber-lined pump is also a double-shell structure. The pump body and pump cover are equipped with replaceable wear-resistant and corrosion-resistant rubber lining (including impeller, front sheath, rear sheath, etc.). The pump body and pump cover are common to the pump body and pump cover of heavy-duty slurry pump and light-duty slurry pump, and their transmission parts and installation forms are also the same.
Gravel pump for single pump shell structure (I. e. without liner). The pump body, pump cover and impeller are made of wear-resistant metal. The connection of the pump body and the pump cover adopts a special clamping structure, and the pump outlet direction can be rotated at will, which is convenient for installation and disassembly.
The inlet of each type of pump is horizontal, and the pump rotates clockwise from the transmission direction.

2. Shaft seal part
There are two types of shaft seal, auxiliary impeller shaft seal and packing shaft seal.

(1) Auxiliary impeller shaft seal: For single-stage pumps or multi-stage series-connected first-stage pumps when the positive pressure value at the pump inlet is not greater than 10% of the pump outlet pressure value, auxiliary impeller shaft seal can be used. The auxiliary impeller shaft seal has the advantages of no shaft seal water, no dilution of slurry, and good sealing effect.
Point.

(2) packing shaft seal: packing shaft seal structure is simple, easy maintenance. However, shaft seal water must be used, and packing shaft seal can be used for working conditions that are not suitable for auxiliary impeller shaft seal.

3. Transmission part
All kinds of horizontal slurry pumps adopt the same series of transmission parts, including brackets and bearing components. The pump shaft has large diameter, good rigidity, short cantilever, and will not bend and vibrate under harsh working conditions. The bearings are selected according to the transmitted power. Heavy-duty single-row or double-row conical roller bearings and cylindrical roller bearings can bear the maximum axial and radial loads of the pump. The bearings are lubricated with grease, and sealing end covers are provided at both ends of the bearing body, labyrinth sleeve and labyrinth ring, can effectively prevent the slurry and other dirt into the bearing, to ensure the safe operation of the bearing, with a high life.

Structural breakdown

shaft seal design

SM, SAH, SHH, SL series pumps can adopt a variety of shaft seal types: auxiliary impeller dynamic seal, material seal, mechanical seal and all kinds of special combination seal.

Vice impeller dynamic seal

Using the pressure seal generated by the impeller and the auxiliary impeller in series, the packing or the mouth sealing ring is used as the stop seal.

Packing seal

regular shaft seal form, suitable for various working conditions, can be equipped with PTFE packing, graphite packing and other special materials, used in corrosive or high temperature conditions. Can be equipped with spray welding ceramic sleeve, suitable for strong abrasion conditions.

mechanical seal

International leading sealing technology, no leakage sealing effect. Container structure, easy to install and replace, different structural forms to adapt to different working conditions. Commercial wipe vice materials using high hardness ceramic and alloy materials, mechanical seal and seal box design and match the medium flow state, so it has high wear resistance and shock resistance, in a variety of harsh conditions can achieve customer satisfaction of the sealing effect.
