Model classification of pressure test pump

The product model division of pressure test pump is a unified model and specification adopted by the joint design group of pressure test pump of China Ministry of Machinery in the design of enterprises designated by the Ministry of Machinery of Haimen City, Zhejiang Province. Carry out the design concept of the third national standard of pressure test pump products. The first is the national standardization, serialization and generalization of the three standards. The electric pressure test pump of this product is DSY type, so it should be 4DSY type. 4- stands for four-cylinder pressure test pump, DSY- stands for pinyin electricity, measurement and pressure. Tell us about the four-cylinder electric pressure test pump. For example, the 4 DSY/KOOC-0/65/6.3 type pressure test pump has a high pressure flow rate of/KOOC-0/65 liter/hour and a rated pressure of 6.3MPa. The joint design group of the pressure test pump has specified 4 DSY/KOOC-0/65/6.3 type and 4 DSY/KOOC-0/00/KOOC type. Later, in order to improve seven kinds of products, China Huatong Company added a Z in front of the 4DSY model, where Z stands for automatic control. Thus, the current standard: Z4DSY voltage-controlled electric pressure test pump appeared. In order to improve the product specifications, Z4DSY 15/ 100 pressure electric test pump was added.

At the same time, the joint design group of pressure test pump of the Ministry of Machinery Industry stipulates: 2S-SY double-cylinder manual pressure test pump, S-SY single-cylinder manual pressure test pump product, 2- stands for two S, S-SY stands for double-cylinder pressure test pump, and S-SY stands for single-cylinder manual pressure test pump. Three kinds of products with different models and specifications all meet the national standards of industrialization and modernization.

2S-SY two-cylinder manual pressure test pump, 2S-SY6.3, 2S-SY 16, 2S-SY25, 2S-SY40, 2S-SY63 two-cylinder manual pressure test pump, five specifications.

S-SY single-cylinder manual pressure test pump, S-SY6.3, S-SY 16, S-SY25, S-SY40, S-SY63 and S-SY80 single-cylinder manual pressure test. Six specifications and models.

This is the classification of pressure testing pump. More specifically, it is China Huatong Pressure Test Pump Company, which has perfected the patented products of Z2DSY and Z4DSY pressure test pumps for China. The models and specifications are strictly divided as follows:

Z4DSY 165/6.3，Z4DSY 100/ 10，Z4DSY63/ 16，Z4DSY40/25，Z4DSY22/63，Z4DSY 15/。

Z2DSY350/3，Z2DSY200/ 10，Z2DSY 165/6.3，Z2DSY350/ 10，Z2DSY 120/ 16，Z2dsy 70。 Z2DSY 15/80, Z2dsy1510, Z2DSY 15/ 130, and * * * are all double cylinders with high flow rate.

At the same time, four-cylinder products with only one high-pressure flow are divided in detail: Z4DSY800/3, Z4DSY450/5, Z4DSY280/6.3, Z4DSY200/ 10, Z4DSY15016 and Z4DSY80.

Z4DSY50/63, Z4DSY45/80, Z4DSY30/ 100, * * * ten specifications and models.

It is the specification and model of China Huatong Perfect Electric Pressure Test Pump. National standard JB/T 9089- 1999
