Fire prevention project fire extinguishing tr--ning description,Teeth machine teaching experimental device

1. Device composition

Fire hydrant series voltage pressure device is m--nly configured by small imported --r pressure tanks/domestic diaphragm -type --r pressure tanks, fire hydrant water pump units, fully automatic spray pump units, pipe valve attachments and control cabinets. Set fire hydrant spray system

Fire hydrant equipment: consisting of water guns, water bands, and fire hydrant.

Two exit fire hydrant, double exit fire hydrant, DN65. Nylon water belt: 65mm, 13m in length, 0.75MPa, water gun: 16mm. At the same time, with standard fire rolls and 20M fire hoses.

The water supply network is composed of the introduction of the pipe fire pipe, fire protection riser, and related valve valve parts. The water supply network and related valve accessories use the materials required by the fire system to regulate the water specifications to meet the pressure stipulated by the fire supply system;

Water supply pipe: 100mm galvanized steel pipe; valve: stop valve, gate valve, safety valve. All valves meet the requirements of the standard standards of the fire protection system and have inspection proof;

The roof fire hydrant is used for the use of fire hydrant to check the pilot of the water system. Single -exit fire hydrant: DN65; water pump junction, fire pool, fire water tank, etc.

Water pump junction: above ground formula, execution standards:

Product Standard "Fire Fighting Pump Combination" GB 3446

Engineering Standard "Code for Fire Fire of the Architecture" GB 50016

"Code for the Construction Quality Acceptance of Water Dr--nage and Heating Projects" GB50242;

Water pump requirements: The amount of essential steam erosion: 4

1. Technical parameters

1. Input power supply: single -phase three -line AC220V ± 10% 50Hz;

2. AC 20W of AC Boarding R--lway Motors 200W

3. The motor speed 1500r/min

4. Insert knife m = 2.5 z = 30

5. Rough parts: φ82 × 20, material requirements are industrial wax.

6. Dimensions: 1000 × 700 × 1250mm

2. Experimental purpose

1. Understand the structural characteristics and uses of various transmission sidelines in the teaching model of the tooth interruption machine, and deepen the perceptual understanding and theoretical understanding of various types of mechanical transmission;

2. By assembling different transmission characteristics, improve students 'hands -on ability and innovative consciousness, and cultivate students' engineering practice

Ability and innovation ability.

3. Deepen the understanding of Fan Cheng's processing gear

Third, performance characteristics:

1. This experimental device is caused by:

Let the knife combination, a single -stage str--ght -to -column gear reducer combination, the combination of turbine grip pole reducer, the diversion combination, the combination of the knife up and down motion, the knife rotation combination, the workpiece rotation combination, and the support cabinet.

2. Tower -bottomed worm worm sn--l reducer transmission module: requires a variety of basic transmission mechanisms, such as: spiral gear mechanism, str--ght tooth cone gear mechanism, cow wheel mechanism, crank slider mechanism, crank rocker mechanism, spiny wheel mechanism, and spiny wheel mechanism, and spiny wheel mechanism, and spiny wheel mechanism, and spiny wheel mechanism, and spiny wheels, and With transmission, ch--n transmission, sliding keys, etc.

It can form a transmission system for the tooth machine tool to form Fan Cheng's motion, cutting movement, feed movement, and knife movement, and a total of five transmission routes.
