1. Transmission of rotational torque

The engine flywheel is the active part of the clutch, and the driven disc and the driven hub containing the friction plate are connected with the driven shaft by the rolling spline shaft. If the spring is clamped, the driven disc is clamped on the end surface of the flywheel of the water pump.

2. Engine torque

That is, it is transmitted to the driven disk by the friction effect between the water pump flywheel and the surface of the driven disk, and then sent to the driving wheel through the driven shaft and a series of components in the transmission system. The greater the clamping force of the spring, the greater the torque that the clutch can transmit.

What are the requirements for the installation environment of the compact rack? How to maintain it?

The compact rack is mainly used in enterprises, books, archives and other places. It has large storage capacity, large occupied area and good storage quality. In order to better preserve archive data, many companies will choose different racks according to different storage items. For example: base map rack, voucher rack, file rack. So what are the requirements for the installation environment of the dense rack? How to maintain it?

Environmental requirements for rack installation

1. The storage place must be waterproof and moisture-proof, because most of the documents are paper. If they are placed in a humid place, even if they have the functions of moisture-proof and dust-proof, they cannot be stored for a long time.

2. Generally, the suitable temperature for storing files is 14-24°C-2°C, and the relative humidity is 45%-60%-5%. The temperature and humidity within this range are better.

3. The size of the space is limited. The installation of the compact rack requires a large area. If the space is small, the compact rack cannot be placed or moved, and it is inconvenient to take documents.

4. The height of the space during the installation of the compact shelf is 30 cm higher than the height of the actual compact shelf. For example, the height of the compact shelf is usually 2.3 meters, and the height of the archive room during installation should be above 2.6 meters. Lower clearance for installation and air circulation.

Floor load-bearing requirements of the installed floor

1. When installing the rack, it is important to consider the load-bearing of the floor and the floor. The usual rack requires a load of at least 200 kilograms per square meter, and the rack manufacturer will consider the size, placement and user requirements between the documents. needs to determine its weight.

2. Therefore, you must measure it carefully during installation. If it fails to meet the load-bearing standard, you can consider how to reinforce it before you can install it. If the load-bearing of the floor or floor cannot be determined, the load-bearing test of the archives should be carried out in time.

Maintenance method of compact rack

Mobile shelving

1. Avoid collisions

After purchasing the compact rack, you should pay special attention to it. When carrying it, you should put it down gently to avoid contact with hard objects. It can’t be put together with hard objects, and it can’t be moved often after placing it, and the floor must be flat.

2. Clean and dust

How much do you know about the types of stereoscopic grow rack systems?

In order to save space and facilitate management, plant planting has become more and more three-dimensional, and various three-dimensional soilless cultivation equipment has sprung up. Many farmers who want to engage in soilless cultivation have no idea what types of three-dimensional grow rack systems are available and how to choose them. Now let me give you a general understanding.

Cascading planter

This is the simplest form of three-dimensional soilless cultivation equipment, that is, to let the plants grow out of the ground plane, and move from the tiled state into the upper and lower stacked space to achieve the effect of intensive planting and management.The characteristics of this form are that the structure is simple and popular, the planting scale is highly flexible, and the management of water, fertilizer, light, wind and temperature is relatively convenient.

Ladder Planter

This form is to stagger the layers of the planting racks, and at the same time compress the depth of each layer.In addition, the soilless cultivation equipment is made of a ladder structure, which is more suitable for planting climbing vines or plants that need to be suspended, such as cucumbers, melons, tomatoes, and strawberries.

Grow racks

A-line planter

Two ladder-type planters are assembled back-to-back, which is the A-shaped planter. In addition to the advantages of ordinary ladder type, this three-dimensional soilless cultivation equipment has the characteristics of stable structure, large planting volume and beautiful shape. But it will be more troublesome when arranging the lighting conditions on both sides of the A word. If it is a pyramid aeroponics equipment, it is also necessary to rotate the tower body according to the position of the sun in order to take care of the planting of multiple surfaces.

Column planting stand

As the name implies, the planting frame of this form is distributed around the column on all sides, with a fan-shaped opening and a spiral upward shape. With different colors, among the three-dimensional soilless cultivation equipment, the appearance is relatively advanced.

WHAT ARE THE PRECAUTIONS WHEN FEEDING CALCIUM HYDROXIDE EQUIPMENT?

Calcium hydroxide equipment is mainly used to produce calcium hydroxide and other chemical products, and almost the entire production is carried out on this equipment. When feeding, you must pay attention to the relevant requirements, and there are also many things to pay attention to.

PRECAUTIONS WHEN FEEDING CALCIUM HYDROXIDE EQUIPMENT

1. The calcium hydroxide equipment cannot meet the classification requirements of micropowder in the cement grinding system, mainly because the specific gravity of the micropowder is much smaller than that of the cement, so the equipment has a weak ability to identify the micropowder.

2. When entering the negative pressure operation, the grinding material is fed from the inlet of the calcium hydroxide equipment of the distributor, and meets the vortex airflow entering the primary air outlet. After being fully dispersed by the suspension dispersing mechanism, the fine powder enters the grading area through the secondary air outlet in the airflow. The resulting horizontal vortex field is graded.

3. The discharge temperature is controlled at about 45 degrees Celsius, and the water content of the discharge is controlled at about 1%. In this way, the agglomeration of finished products is prevented, and the efficiency of powder selection and the waste of slag discharge are improved.

4. The fine powder enters the rotating cage, and the negative pressure air is pumped into the subsequent dust collector from the fine powder outlet, and the finished product is collected by the dust collector. The coarse powder falls into the cone, is discharged through the coarse powder outlet, and returns to the mill for grinding again.

What factors will affect the heat sealing effect of valve bag making machine

The valve pocket bag making machine can bond the bottom by heat sealing and gluing. At present, the heat sealing process is widely used in the market. Many factors will affect the heat sealing effect of the valve bag. Factors will affect the heat sealing effect of valve bag making machine!

Factors affecting the heat sealing effect of valve bag making machine

1. Heat sealing layer material

The type, quality and thickness of the heat-sealing layer material have a decisive influence on the heat-sealing strength. The thickness of the heat sealing layer material is generally between 20 and 80 μm, especially 100 to 200 μm. The commonly used heat sealing materials for composite packaging include CPE, EVA, CPP, hot melt adhesive and other blending modified films or ionic type. Resin co-extrusion. The heat sealing strength of the same heat sealing material increases with the heat sealing thickness, and the thicker the surface layer material, the greater the heat sealing strength.

HT120-IA Paper Tube Machine

2. Heat sealing temperature

The heat sealing temperature affects the direct heat sealing strength, and the unevenness of the melting temperature of various materials directly determines the heat sealing temperature. The practically selected heat-sealing temperature is often higher than the melting temperature of the heat-sealing material, which is affected by the heat-sealing pressure, the bag-making speed and the thickness of the composite substrate. The smaller the heat sealing pressure, the higher the required heat sealing temperature; the faster the machine speed, the higher the required heat sealing temperature. If the heat-sealing temperature is lower than the softening point of the heat-sealing material, it is difficult to make the heat-sealing layer truly seal. If the heat sealing temperature is too high, it will reduce the heat sealing strength of the seal and the impact resistance of the bag, and it is easy to damage the melt extrusion of the heat sealing material at the welding edge.

WHAT ARE THE BASIC PRINCIPLES OF THE FORGING PROCESS?

Forging is a processing method that uses a forging machine to apply pressure to a metal blank to plastically deform it to obtain a forging with certain mechanical properties, certain shape and size. Forging (forging and stamping) is one of the two major components.

Through forging, defects such as as-cast looseness produced by the metal during the smelting process can be eliminated, and the microstructure can be optimized. At the same time, due to the preservation of the complete metal streamline, the mechanical properties of forgings are generally better than those of castings of the same material. So do you know the three basic principles in the forging process? Below, the relevant personnel of Chinese professional forging manufacturers will give you a detailed introduction, let’s learn about it together!

Rocker arm forgings

1. THE PRINCIPLE OF CONSTANT VOLUME

When forging each forging, the material should be calculated first, and the material should be cut according to the weight and fire consumption of the forging. (The basic formula for calculating the material G = ρV G – the weight of the billet ρ – the specific gravity of the material V – the volume of the billet) When calculating the material, the volume of the raw material must be calculated (due to the different specific gravity of various raw materials) and then multiplied by the specific gravity to get the forgings The weight of any forging is closely related to the volume before and after forging, such as pier thickening, drawing length, punching, mandrel drawing length, shoulder pressing, misalignment, bending and twisting during forging. Its overall volume remains the same, but the shape is changing, such as from a circle to a square, from a square to a circle, from an octagonal to a circle, etc., but the volume remains unchanged.
