Ordinary employees developed plunger pump Versail extractor successfully
Stage special electric hoist belongs to chain electric hoist, also called hoist. The stage electric hoist is designed and manufactured in strict accordance with the requirements of touring performances and touring exhibitions. The surface is treated with black paint, bright and durable. The 110-volt control circuit is heat-treated. Adjustable screw limit switch, higher reliability, chain galvanized, not easy to rust, lubricating grease is installed in the gear box to prevent oil droplets from penetrating into the stage, the motor of the hoist is sealed in the aluminum steel ring cylindrical shell It is suitable for connecting with various controllers and circuit distributors.
The characteristics of stage chain electric hoist: advanced performance structure, small size, light weight, reliable performance, convenient operation, wide application range, very convenient for lifting heavy objects, loading and unloading work, maintenance equipment, lifting goods, it can also be installed in Suspended I-beams, curved tracks, jib crane guide rails and fixed lifting points for lifting heavy objects.

Because the piston pump is often washed by high-pressure hydraulic water, it is easy to pierce irregular grooves and pitting and damage. Usually, the Versail extraction hook is used for extraction and replacement, but the three damaged bearings of the Versail seat will be broken, which will cause the Versail extraction hook to be scrapped. It can't be used after 3-5 times. Forcibly extracted with other tools, although the damaged Verne seat can be taken out, it will cause damage to the inlet valve cavity of the plunger pump, which will reduce the pump efficiency during operation. Therefore, in the production and maintenance process, it is urgent to develop a new type of Versail extractor to solve the problem of difficult extraction of damaged Vernier.
Workers' technician Du Shengli often suffers from difficulty in extraction of the Verni seat and damage to the inlet valve cavity during the maintenance work of the daily injection pump. According to the principle of moment force, he relied on the torque generated by the nut and the screw to successfully develop a new type of Versail extractor, which can be used to extract the damaged Versail seat by lifting the two fixed round end bases connected to the Versailles. the goal of.
Since April 2007, after repeated trials by Du Shengli and his companions, the new Versail seat extractor has been successfully tested on the 3ZP piston pump and has been widely used in the Sancai Center. Completely solved the problem of difficult extraction of damaged Versailles. The time for extracting Vernier from the new Versail extractor has been reduced from less than half an hour to less than 10 minutes, and the number of repeated use has been greatly improved. It can only be increased from 3-5 times to more than 15 times. The cost of valve core and valve seat is 50,000 yuan, and the pump efficiency of the plunger pump is increased by 4 percentage points. At the same time, the on-site operation intensity of the worker can be reduced, the workload can be reduced, and the maintenance time of the equipment can be greatly shortened.
scope of application
The stage chain electric hoist generally has a lifting capacity of 0.1-7.5 tons and a lifting height of 3-50 meters.
