The design standard of laboratory ventilator is very important. In order to improve the utilization rate of laboratory, control the cost and quality at the same time, many problems need to be considered at the beginning of the design of laboratory, in which many factors such as the function and ventilation of laboratory need to be considered.
Design Standard of Laboratory Fume Cabinet Purpose:
1: Discharge the volatile gas in the process of honing quality inspection of cylinder block outdoors.
2: The aerosol used in crankshaft flaw detection is discharged outdoors, and the extracted aerosol is filtered by a filtering system to ensure that the discharged gas with color does not affect the surrounding environment.
When designing standard natural lighting for laboratory ventilator, if someone faces the window, there will be glare, while the back will cause shadows on the table, so it is not suitable for the laboratory to have the experimental table parallel to the external wall of the lighting window; when arranging the experimental table, there should be a certain distance between the two.
When the design standard of laboratory ventilation cabinet sets up Island central table disposal pipeline, such as digging trench on the floor and adding cover board, it is easy to maintain, but there will be leakage and fluid accumulation problems; if the floor is directly buried, it is not conducive to maintenance; once the problem arises, it will be cut, checked and replaced, but there will be no leakage and fluid accumulation problems; if the buried pipeline is pierced through the floor, there will be leakage problems, and downstairs. High precision instruments should not be set up.
实验室通风柜设计标准因而为易于埋藏管线，倡议设置半岛式台。 化学实验台选用的长度普通是1.2米/人，假如是有机实验室，普通是1.5米/人;台面高度中国通常为850mm，在美国、西班牙、德国为900-920mm，在日本为800mm;台面宽度通常在600mm-750mm之间，假如是双面的，台面不得超越1500mm。 为确保实验台整体美观，减少台面的拼缝，也便于调试，进步施工进度，倡议台面尽量选用整片台面、规范柜体组合;伸膝凹口宽度坚持在600-1100mm之间;选用的试剂架深度以能并列放置两瓶500ml的中型试剂瓶为宜。
Laboratory ventilation cabinet design standards, therefore for easy burial of pipelines, the proposal to set up a peninsula-type central platform. The length of the chemical test-bed is 1.2 m/person. If it is an organic laboratory, it is 1.5 m/person. The height of the test-bed is 850 mm in China, 900-920 mm in the United States, Spain and Germany, and 800 mm in Japan. The width of the test-bed is usually between 600 mm and 750 mm. If it is double-sided, the central table should not exceed 1500 mm. In order to ensure the overall beauty of the test bench, reduce the joint of the bench, facilitate debugging and improve the construction progress, it is suggested that the bench should choose the whole bench as far as possible and standardize the combination of cabinets; the width of the knee extension concave should be between 600 and 1100 mm; the depth of the reagent rack should be able to place two 500 ml medium-sized reagent bottles side by side.
In the design of ventilation system, the design standard of laboratory ventilation cabinet should include the plane size of the room, the floor, the floor clearance height, the room beam and floor height, the ceiling and floor height, the planned position size of ventilation products in the room, the location size of wall windows, the floor where the roof is, the location size of fans placed on the roof, and the customer's request row. The direction of the air duct and the cross-section size of the exhaust well are well known, and then the planning and design are stopped according to the size. As long as we are familiar with the measurement data of the relevant field, the setting of the ventilator can give full play to its advantages.
