The internal and external structure of 1 water resistance test chamber is high-grade stainless steel plate, which has been sprayed. The water inlet end is softened, but the nozzle may be blocked if water stains are left on the nozzle due to frequent cleaning. Every time the test is finished, use air to spray the water in the nozzle.

2. The passive bearing pedestal (ipx1x2) is located above the equipment and has four groups. The bearings should be lubricated with lubricating oil every season.

3. The passive (ipx3x4) position is on the right side of the equipment, and the lubricant shall be applied quarterly

4. The passive chain is located at the rear of the equipment, the upper cover must be opened, the transmission chain position and the upper part of the equipment should be lubricated with chain lubricating oil every season, and the chain lubricating oil should be used every season.

Note: 1. Chain lubricating oil shall not be lubricated with other butter or other solid grease to prevent speed sensor failure.

2. The 60 teeth of the speed sensor and the gear disc shall not be lubricated with any grease.

5. There are two groups of water filters at the inlet side of the shaft seat, which should be soaked in NaCl (salt) for 24 hours every year, and then washed with clean water.

2: The steps are as follows:

1. Open the water inlet valve in the closed state.

2. Remove the left and right sides of the transparent hose.

3. Loosen the black upper cover in a counter clockwise direction Q, pull it up for 10 cm, put 2 kg / bottle of 4 kg sea salt into the bottle, then screw the black upper cover in a clockwise direction, and lock the transparent hose back (the outlet end is not locked at first, and the wastewater drainage pipe needs to be connected at that time), and lock it back in the correct direction according to the water inlet and outlet.

4. When standing for 24 hours, open the water inlet valve, and connect the outlet end with the temporary drainage pipe, the waste water pipe shall be discharged to the water hole.

5. Rinse for 30 minutes.

After 6.30 minutes, connect the water inlet pipe of the water tank to the filter pipe.

7. The small filter element on the left side of the water resistance test chamber depends on the water quality. It can be used for six months. If the filter element is dirty by naked eyes, it needs to be replaced. When replacing the filter element, insert the filter element wrench into the upper end of the filter cup from bottom to top and then turn it anticlockwise. When the filter cup is loosened, hold the filter cup with both hands without using a wrench until the whole filter cup is separated. Take out the filter cup, take out the old filter element, pour out the water, clean the inner liner of the filter cup, and then install the new filter element.

(the round hole in the middle of the filter element must be located in the center of the filter cup) hold the filter cup with both hands, screw it clockwise, and then tighten it with a wrench.

8. When cleaning the floor in the tank, use general floor cleaner. Brush with a brush if necessary,

9. The outer layer of the equipment shall be cleaned with general cotton cloth and water, or water wax when necessary.

Constant temperature and humidity test box is also called constant temperature and humidity test machine, constant temperature and humidity test box, constant temperature machine or constant temperature and humidity test box, which is used to test the performance of materials in various environments and test the heat resistance, cold resistance, dry resistance and humidity resistance of various materials. It is suitable for testing the quality of electronic, electrical, communication, instrument, vehicle, plastic products, metal, food, chemical, building materials, medical, aerospace and other products. Compliance standards: GB / t5170.5-2008, GB / t10586-2006, GB / t2423.1-2008 test a, GB / t2423.2-2008 test B, GB / t2423.3-2006 test Ca, GB / t2423.4-2008 test dB.

Model differentiation

According to the test requirements and standards, the constant temperature and humidity test chamber can be divided into "desk type" and "vertical type". The difference is that the temperature and humidity can be different. The vertical type can do low temperature and drying below normal temperature, while the desk type can only do high temperature and humidity above normal temperature.

Control instrument

The test chamber adopts imported temperature and humidity controller, p.i.d high-precision control, to eliminate long-term unstable operation; humidity is visual display control, to abandon the defects of the original temperature and humidity contrast

display resolution 

Temperature: 0.1 ℃ (display range)

Time: 0.1min

Humidity: 0.1% RH (temperature and humidity test equipment)

Temperature sensor: PT100 platinum resistance thermometer

Control mode: heat balance temperature and humidity control mode

The p.i.d + S.S.R system is used for temperature and humidity control

With the function of automatic calculation, the temperature and humidity change conditions can be corrected immediately, making the temperature and humidity control more accurate and stable

Subsidiary function

Fault alarm, cause and handling prompt function

A fail-safe mechanism 

Calendar timing function (auto start and auto stop)

Self diagnosis function

brief introduction

The constant temperature and humidity test box is suitable for testing the quality of electronics, plastic products, electrical appliances, instruments, food, vehicles, metals, chemicals, building materials, aerospace, medical and other products. This machine is specially used to test the heat resistance, cold resistance, dry resistance and moisture resistance of various materials.

working principle

The main working principle of constant temperature and humidity test box: dehumidification principle; humidification principle; refrigeration principle; heating principle and structure introduction

This equipment selects high-quality materials, uses the most advanced domestic processing equipment processing molding, shell surface spray treatment, beautiful, smooth. Coordinated color matching, angular design, smooth and natural lines. The inner liner is made of imported high quality stainless steel plate with reasonable design and durability. On the premise of meeting the national standards, the equipment is more practical and easy to control on the basis of stable performance in all aspects. Moreover, the equipment is easy to install, easy to operate, and basically does not need routine maintenance.
