How to maintain the constant temperature and humidity test chamber?

The constant temperature and humidity test chamber is the most used instrument in environmental reliability tests at present. It is widely used in electronic, electrical, military, plastic, hardware, chemical industry, and other industrial fields, such as electronic components, auto parts, notebook computers, and other virtual climate environment tests.

Routine maintenance of constant temperature and humidity test chamber:

First, open the door of the test chamber and turn on the main power downward.

Turn the drain valve to the open position, the water is discharged into the lower water tank by the return pipe, and all the water is discharged into the lower water bucket.

Pull out the return pipe, connect the motor with the power plug, and pull out the outlet pipe of the return pipe.

At this time, the outlet of the motor will leak is a normal phenomenon. Please press the outlet of the motor with your finger and quickly pour out the water in the bucket.

In this way, all parts of the constant temperature and humidity test chamber can be cleaned.

After cleaning, put the lower bucket into the positioning return pipe, and plug the connecting head of the power line of the pumping motor and the outlet pipe of the pumping motor back into the return pipe.

Open the lower bucket cover, pour in distilled or pure water, drain valve to turn (close) position.

Turn on the power supply of the switchboard, water will be automatically pumped from the bucket, and the motor will pump water to each part of the waterway system.

What incubator should I use for fungi?

图片
There are many different types of incubators and the choice of the incubator should depend on what is being cultured. If the microorganism to be cultured is aerobic, then a normal incubator is sufficient; if it is anaerobic, then you need to buy an anaerobic incubator; if it is algae or fungi, it is better to have a light incubator. A light incubator is a piece of high-precision constant temperature equipment with light function; a light incubator is a special constant temperature incubation device for the cultivation of bacteria, molds, microorganisms, and breeding tests, especially practical for biological engineering, medical research, agriculture, and forestry science, aquaculture, animal husbandry and other fields engaged in scientific research and production use of the ideal equipment.　 The main technical parameters of the fungal incubator in the microbiology room of the laboratory require 1: Temperature requirements: 2 ~ 48 c, the temperature inside the incubator temperature u

Laminar flow Cabinet architecture introduction

图片
Laminar Flow Cabinet Clean Bench, also known as laminar flow Cabinet, can be mainly divided into two- person single, single side double side, horizontal vertical, etc. The structure is divided into the box, table, bracket, support foot, exhaust pipe, HEPA filter, pre-filter, etc.   Laminar flow cabinet design should have sufficient strength and stiffness, the weight should be light under the premise of good stability, the joints should be tight, according to the needs of the support foot can be self-locking structure universal wheel, but for the high requirements of seismic workbench without support feet and universal wheel, the operating area of the working surface can be made independent of the box platform. The inner surface of the single table is made of three sides of the wall. The wall surface is smooth and the joint is sealed. The glass and metal connection parts should also be sealed. The negative pressure air duct should be designed so that the air duct, plenum, filter, and su

The Control system is the core of the constant temperature and humidity chamber

The Control system is the core of the constant temperature and humidity chamber , it determines the temperature rise rate of the text chamber, precision, and other important indicators. Now the controller of the test chamber mostly adopts PID control, but also a few adopts PID and fuzzy control phase combination control mode. Because the control system of the thermostatic oscillator basically belongs to the category of software, and this part in the use of the process, generally there will be no problems. In the constant temperature and humidity chamber refrigeration principle diagram, we introduced the temperature and humidity chamber refrigeration system several important components of the working path. So how do these components work? The refrigerant is adiabatically compressed to a higher pressure by the compressor, and the work is consumed to raise the exhaust temperature. After that, the refrigerant isothermally exchanges heat with the surrounding medium through the refrigerant c
